Abstract:

End stage liver disease (ESLD) is a multi-system disease that complexly and mutually interacts with other body organs. The heart is one of the organs most adversely affected by liver disease both directly and indirectly. Cardiac dysfunction in the setting of cirrhosis may contribute to mortality as high as 50% post liver transplantation. The spectrum of heart diseases associated with liver cirrhosis includes 3 major groups:

1.            Underlying heart disease aggravated by cirrhosis

2.            Heart disease that is caused by a pathologic process that concomitantly affects the heart and the liver

3.            Cirrhosis-associated cardiac disease, which may be vascular, myocardial or pericardial.

Liver transplantation while considered the definitive treatment of patients with ESLD, can independently contribute to further deterioration of pre-existing cirrhosis-associated cardiac dysfunction. These adverse effects occur as a result of acute changes in loading conditions, and the liberation of inflammatory cytokines and other mediators during graft reperfusion. Furthermore, following liver transplantation there is an increased risk of adverse cardiac events associated with chronic immunosuppressive therapy. Thus, such patients require a thorough cardiac evaluation prior to being deemed acceptable liver transplant candidates.

A thorough cardiac evaluation of liver transplant candidates is a challenging task, however. Altered cardiac response to stress, the heterogeneity of cardiac disease in liver transplant candidates, and the paucity of well-designed studies investigating preoperative cardiac testing; all explain the current lack of agreement on a single best screening strategy to optimize perioperative and postoperative outcomes.

This talk will discuss the following: profiles of cardiac dysfunction in ESLD, short and long term cardiac dysfunction associated with liver transplantation, and the preoperative evaluation of liver transplant candidates in light of the current evidence, appraising its limitations. Also, this talk will propose avenues for future investigation of cardiac function in liver transplant candidates.

Abstract:

Colorectal cacner is the second cause of death in the world and genomic alteration palys an importan role in this desase. Much of the underlying genetic ‘cancer driver’ mutations in sporadic colorectal cancer (CRC) have not been characterized by race.

Here, we report the identification of distinct novel variants from CRC patients in mismatch repair (MMR) genes MHS3 and MSH6, and APC. We developed a panel of 20 frequently altered colon cancer genes for targeted sequencing in 138 colon tissues using next generation sequencing to examine 98.8% of the targeted exons and splice junctions at a depth of sequencing that allowed for high confidence variant calling. After alignment and variant calling, we annotated the variants with information from the 1000 Genomes Project, COSMIC, Polyphen2, and PFAM domain and transcription factor motifs. Excluding synonymous SNVs, 212 deleterious variants in adenoma, 760 in advanced adenoma, and 2624 variants in tumors were detected. Novel variants (1591 and 1363) were found in MMR genes (MSH6 and MSH3) and APC gene, respectively. These findings further highlight the relevance of APC gene in CRC onset but also the potential underestimation of the MSI-H in sporadic CRC as many of the novel mutations in MMR genes detected here were of a deleterious nature with an therapeutic interest.

Abstract:

The new Anopress© device has been promoted as a portable, quick and reliable new device which can reproduce easily pressures measurements of the anal canal. The aim of these studies was to formulate normative data for this newer device by recording the anorectal function in asymptomatic subjects. We also intended to assess its practicality and acceptability in daily clinic in symptomatic patients.

Anorectal function was assessed in 150 asymptomatic volunteers using the Anopress©. All volunteers were tested in a standardised way in accordance with the study protocol and normative values were obtained. Sixty patients with faecal incontinence were retrospectively evaluated. A cohort of other 60 patients had both Anopress and high resolution manometry.

Further statistical analysis allowed calculation of normal values for this newer device. All the patients tolerated the procedure. When comparing the two manometric evaluations, there were significant differences in terms of pressures likely due to the different technology of the two machines.  

Anopress© appears to be an easy, quick and a straightforward way of measuring anal canal pressure. One of the main advantages is the solid state probe which is able to represent the pressures of the whole anal canal. This newer device is also portable and we could use it easily in clinic at the bedside.

Title: Biosimilars in inflammatory bowel disease: A review of post-marketing experience

Time : 13:45-14:45

Speaker
Biography:

Dr. Vito Annese achieved his MD in 1981 and subsequently the CCST in Internal Medicine and Gastroenterology at the Catholic University of Rome Italy. He has over 30-years of experience in gastroenterology, with specific interest in functional and inflammatory bowel disorders. He authored more than 250 peer reviewed publications. In the last 10-years he has been head of Gastroenterology at the Research Hospital of S. Giovanni Rotondo and at the University Hospital Careggi of Florence and aggregate professor at the University of Foggia and Florence in Italy. Since September 2016 is Consultant Gastroenterologist at the Valiant Clinic of Dubai.  

Abstract:

The introduction of anti-tumor necrosis factor alpha (anti-TNFa) antibodies about two decades ago, has revolutionized the management of inflammatory bowel disease (IBD). However, they are also expensive and their cost can lead to restricted access for many patients. Inflximab has been the first anti-TNFα agent to be used and the first to lose the patent, whereas CT-P13 (Celltrion) has been the first infliximab biosimilar to be available. The clinical trial program of CT-P13 have been performed in patients with ankylosing spondylitis (AS) and rheumatoid arthritis (RA). Both were randomized, double-blind, multinational trials with 30 weeks of treatment, subsequently followed-up to 54 weeks with a further open-label 48-week extension and switch from infliximab to CT-P13. All these studies have demonstrated pharmacokinetic equivalence and clinical efficacy in both AS and RA up to 102 weeks, also after switching. The indication of CT-P13 has been extended since 2013 by EMA and more recently by FDA and Health Canada also to IBD.

So far no controlled trials are available in IBD, therefore we have made an extensive review of the available open label case series of IBD patients treated across the world. More than 600 IBD patients were evaluated, 39 in paediatric age, and 183 switched from inflximab. In most cases, only a clinical evaluation was performed. The mean efficacy was 72%, the rate of adverse events 10.4%, and the rate of infusion reactions was 5.5%. These findings are very much comparable to the experience with infliximab, waiting for the data of the controlled trials.

Abstract:

Sleeve gastrectomy is traditionally performed with the aid of 5 to 7 abdominal trocars. We aim to present our experience concerning laparoscopic sleeve gastrectomy for morbid obesity, with a more minimal invasive approach, using three ports- trocars. Laparoscopic Sleeve Gastrectomy (LSG) is traditionally performed using 5 to 7 abdominal trocars. By reducing the number of trocars, parietal trauma, pain and hernia risks can be minimized.We present our 3-year experience concerning LSG for morbid obesity using three trocars, with emphasis on a simple suture-based trocar-free liver retractor. Methods: We retrospectively analyzed 65 patients who underwent LSG for morbid obesity, from May 2014 to December 2016. Three trocars are typically used: one 10-mm periumbilical optical trocar and two 12-mm trocars on the midclavicular lines. A suture is percutaneously inserted and fixed to the right crus of the diaphragm. Careful traction lifts the left hepatic lobe offering better surgical field and access to the gastroesophageal junction. A gauze is used to protect liver parenchyma from possible injury. Furthermore, sectioning and stapling of the stomach is performed before the gastroepiploic division, reducing the need of another left sided trocar. Results: All the patients had an uncomplicated recovery. No liver injury or wound problem was mentioned. Conclusions: The placement of a suture at the right crus of the diaphragm can reduce the number of trocars, leading to less postoperative pain, risk of hernia and better cosmetic outcome without compromising the safety of the operation or the rate of postoperative complications.

Abstract:

Objective

To determine differences in procedure duration, length of stay, outcomes and cost based on types of surgery in the year 2004-5 and 2014-15.

Methods

The study design was a 10 year interval retrospective study conducted in a district hospital in Queensland, Australia. Data were extracted from hospital record for the years 2004-5 and 2014-

15.  Incomplete and inaccurate data were excluded from the study and a total of 247 records were included in final analysis. Fischer’s exact test, Chi-square test and Mann-Whitney U test with 0.05 level of significance were used. Odds ratio with 95% confidence interval were also calculated.

Results

Patients treated with laparoscopic surgery had significantly shorter hospital stay than those treated with mini-open surgery (p<0.001), and it was consistent for both time period. Antibiotic use and postoperative complications were significantly higher in mini open cholecystectomy cases (p<0.05). In both time period, laparoscopic cholecystectomy showed significantly less inpatient complications compared to mini open cholecystectomy. Lack of cost components restricts direct comparison of cost, however increased complication, antibiotic use and longer stay suggests high indirect cost in patients treated with mini open cholecystectomy.

Conclusion

Laparoscopic cholecystectomy has become the preferred management of acute cholecystitis. This research provides evidence on improved intraoperative and postoperative outcome in laparoscopic cholecystectomy compared to mini open cholecystectomy. Shorter hospital stay, less postoperative complications and less antibiotic use make this technique more cost-effective. However, longitudinal study using cost effectiveness analysis in future will provide robust conclusion.

Title: What can a new endoscopic Ling classification do for achalasia?

Time : 12:45-13:15

Speaker
Biography:

Yaqi Zhai, MD, chief doctor of department of Gastroenterology and Hepatology of Chinese PLA General Hospital, has completed his MD degree at the age of 26 years, from Chinese PLA medical school. He was dedicated to digestive endsocpic tunnel technique and had published more than 10 papers in reputed journals. He was also a member of academic group of Capsule endoscopy and enteroscopy of CSGE.

Abstract:

Peroral endoscopic myotomy (POEM) is a new minimally-invasive endoscopic method for achalasia, being expected to be the first treatment choice with satisfactory short and morderate term outcome.  We performed our first POEM in Oct 2010, and gradually found not all the achalasia patients were eligible and euqually safe to undergo POEM. Although achalasia had been staged or classified on radiography or manomentry, there was no endoscopic classification. We retrospectively analyzed the endoscopic features of 976 achalasia patients in our endoscopic center, and proposed a new endoscopic Ling classification. Acorrding to presence of muti-ring,crescent-like structure and diverticulum, achalasia was divided into three subtypes:type â… , type â…¡(a,b,c), type â…¢. Then prospective study enrolling 341 patients with POEM was performed to evulate the clinical value of the achalasia. Patients with different Ling subtypes suffered the similar degree of symptoms according to Eckardt scores. Yet the Ling classfication had significant correlation with symptom duration and lower esophageal sphincter pressure (LESP). The patients with longer duration were more likely to developed Typer â…¡c and â…¢. And LESP of these Typer â…¡c and â…¢ patients was obviously lower than the others. The overal success rate of POEM was 97.7% within 1-year follow-up and there was no significant difference among different subtypes. Whereas Ling classficaiton had significant correlation with complications, such as gas-related adverse and mucosal perforation. Ling â…¡c was showed to have the highest risk of complication and a modified POEM with short tunnel was demonstrated effectively by us.

Abstract:

With increasing incidences of hepatitis, fibrosis and cirrhosis due to lifestyle changes, food habits, drug adverse effects, alcoholic and fatty damage, it is relevant that focus should now be on prophylactic and preventive measures, to take care of day to day factors causing cellular injury and inflammatory processes. Traditional foods and traditional therapeutic systems the world over including Ayurveda point to the benefits of regular herbal intake, which indirectly provided a prophylactic antiinflammatory activity and show antiarthritic action.

Slurry comprising herbal extracts was prepared by suspending in a solution of the excipients, dissolved or suspended in sufficient water and lsopropyl alcohol (IPA) to make the slurry sprayable. After milling through a machine adapted for grinding suspension in order to reduce the particle size of extract, the suspension was applied on the excipient pellets in the classic pharmaceutical fluidized bed coating device, which consists simply of a vertical cylinder with an air-permeable bottom and an upward spraying nozzle close above the bottom, or a downward-spraying nozzle mounted above the product mass. The temperature of the fluidizing air was balanced against the spray rate to maintain the mass of pellets at the desired level of moisture and stickiness while the coating was built up. A finishing layer over the extract layer of 1 % of an anti- static ingredient such as talc or silicon dioxide, simply dusted on the surface of the pellets and other coats were applied.

The pellets were made palatable and coloured with colourants and flavours added to increase patient compliance for daily intake as prophylactic food, and optimized for uniformity of content, dissolution and moisture content, and then for anti-inflammatory and hepatoprotective activity. The Hepatoprotective pellet (HDT) treatment stimulated hepatoprotective effects that were proven by attenuating serum AST and ALT activities. The antioxidant activities of the HDT pellets can ameliorate oxidative stress contributing to the amount of intracellular antioxidant enzymes, which was confirmed by GSH and CAT assay. Centrilobular necrosis, lymphocytes infiltration and steatosis were apparent in CCl4-treated group, whereas administration of the HDT significantly reverses these abnormal indexes. This indicates that HDT can ameliorate oxidative stress to preserve hepatic function and hepatic injury induced by CCl4.

Abstract:

Background: Sacroccygeal pilonidal sinus disease (SPSD) is a worldwide health problem, affecting young adult, mainly male, with a tendency for recurrence. Various modalities have been used for treating this condition. Karydakis procedure is one of most commonly used asymmetric flap for treating this condition.

Objective: the study aimed to evaluate Karydakis procedure with tie-over compressing sutures instead of routine use of drain in treatment of SPSD

Design: prospective randomized controlled clinical study conducted between January 2010 and January 2015.

Settings: the study was conducted in Minia university hospital.

Patients: the study included 154 patients. Patients were randomly assigned into 2 groups. Each group included 77 patients.

Interventions: Group 1 operated by standard Karydakis procedure and group 2 by Karydakis procedure with tie-over compressing sutures without drain.

Main outcomes and measures: incidence of seroma formation, wound complications length of hospital stay, off-work time and recurrence rate

Results: all patients discharged on the same day of surgery in group 2 VS. mean hospital stay of 4.9 ± 2.4 day in group 1. No patients developed seroma in group 2 VS. 7.8% in group 1. 1.3% developed wound infection in group 2 VS. 9.1% in group 1. The average time for return to work in group 2 was 10.2 ± 1.4 days VS. 12.6 ± 4 days in group 1. No recurrences were noted in group 2 VS. 2.6% in group 1

•           The limitations: The feedback about postoperative pain and patient's satisfaction about the scar were not investigated. The extent of the disease on both group were not investigated. Relatively short duration of follow up to accurately weight recurrence rate.

Conclusion: Karydakis flap with tie-over compressing interrupted sutures without drain is safe, one day surgery with least complications rate.

Speaker
Biography:

Daorong Wang, Chief Physician, Professor, Ph.D.Supervisor. The deputy director at the Gastrointestinal Center and department of Gastrointestinal Surgery at Subei People's Hospital of Jiangsu Province, China

Abstract:

This review aimed to summarize the basic research on and clinical applications of uncut Roux-en-Y gastrojejunostomy. We reviewed the available literature on uncut Roux-en-Y gastrojejunostomy, which is a modification of the Billroth IIwith Braun’s anastomosis in which a jejuna occlusion is fashioned to avoid Roux stasis syndrome. In this paper, we present the findings of our literature review. The original uncut technique was associated with dehiscence or recanalization of the jejunal occlusion, and was therefore not widely applied. However, with recent improvements in the method of jejunal occlusion, the uncut Roux-en-Y reconstruction may be an appropriate alternative for digestive tract reconstruction after distal gastrectomy. The uncut Roux-en-Y gastrojejunostomy is a controversial yet promising method of gastrointestinal reconstruction after distal gastrectomy.

Abstract:

Single Port Laparoscopic Surgery (SPLS) is a technique which is increasing in popularity. The benefit of SPLS in complex Crohn’s disease (CD), which includes a significant cohort of young patients sometimes needing multiple operations, has not been comprehensively assessed. This study analyses our experience with this technique.

Patients who underwent SPLS for CD were included. Data were collected prospectively from January 2013 to December 2015. Ileocolic resections, right hemicolectomy, small bowel stricturoplasties and resections were included in the complex CD cohort. Primary and re-do operations were analysed separately.

Seventy-five patients were included in the study: (59 ileocolic resections, 16 small bowel stricturoplasty/resections). Of the total, 41 were primary resections and 34 were re-do resections. The median age was 39 years (Range 14 years – 74 years), and the median hospital stay was 7 days (Range - 3 days – 28 days). The total complication rate was 31.5% most of which were Clavien-Dindo type 1 and 2.  There was no difference in operating time, average blood loss, conversion rates, complication rate and hospital stay, between those who had primary or redo surgery.

In our experience SPLS can be performed safely in patients with complex Crohn’s disease even in redo surgery. There may be some technical advantages to the procedure in this group of patients

Abstract:

Cancers caused by immunosuppressant drugs represent a minority of the incident cancers observed in patients with IBD. Thiopurines can promote cancer in several different ways, such as carcinogenic mutations of cell DNA, impaired tumor-cell immune-surveillance, reduced number and/or function of immune cells, and facilitating the proliferation of cells with microsatellite instability. However, several studies conducted in referral centers and adequately powered nationwide studies have suggested that cancer risk in general is not increased. In a recent meta-analysis, the overall standardized risk ratio (SIR) for lymphoma considered in the population studies was significantly increased in IBD patients receiving thiopurines, (5.7, 95% CI 3.2-10.1), but not in former users or patients who had never used these drugs. The absolute risks were globally higher by a factor of 2 to 3 in men compared with women, irrespective of age and drug exposure. The highest absolute risks for lymphoma (any type) were found in patients over 50 years (2.6/1000 patients) and in males under the age of 30 (estimated crude risk: 1 to 2/1000 patients). Hepatosplenic T-cell lymphomas (HSTCLs) occur almost exclusively in males under the age of 35 who are exposed to thiopurines. However, over 80% of the cases of HSTCL occur after the first 2 years of combination therapy of thiopurines with anti-TNF. Data suggesting an excess risk of non-melanoma skin cancer (NMSC) in IBD patients being treated with thiopurines have emerged from several studies conducted in the last five years and a recent meta-analysis, which found a pooled adjusted HR for NMSC in thiopurine-treated IBD patients of 2.3. The carcinogenic effect of thiopurines has been attributed to increased UVA-induced DNA damage, increased production of reactive oxygen species in skin epithelial cells. Since 1995, several studies have investigated the cancer risk associated with TNF-alpha antagonists used in IBD. Most patients treated with these agents in these studies also used (or had used) thiopurines, so it is difficult to attribute the findings to anti-TNF therapy alone. More recently an adequately powered nationwide study in Denmark have confirmed the data of meta-analysis and pooled analysis for infliximab and adalimumab excluding an excess of risk. It is not clear whether concomitant anti-TNF treatment increases the risk of thiopurine-associated lymphoma, except for the hepatosplenic T-cell variety. The results of a recent meta-analysis indicate that the risk of melanoma is mildly increased (37%) in IBD patients, independent of the use of biologic therapy. In a large nested case-control study performed with data from a large health insurance claims database, the use of TNF-alpha antagonists was independently associated with an increased melanoma risk in patients with IBD (OR=1.9; 95% CI, 1.1-3.3), but in a Danish cohort the adjusted odds ratio was non-significant. Reliable data regarding risk of cancer and therapy with Methotrexate and Cyclosporine in IBD are lacking. Data on methotrexate related to rheumatologic experience do no report an excess risk of solid cancer or hematological malignancies. Calcineurin inhibition is associated with an unequivocal excess risk of cancer in the post-transplant state, but is generally dose and duration-dependent; therefore, is not an issue for IBD.

Title: Transient Elastography in Non-cirrhotic Portal Fibrosis: A Comparative Study With Child A Cirrhosis In a Tertiary Care Centre

Time : 16:45-17:10

Speaker
Biography:

Mohammed  Noufal B has completed his MBBS and MD internal medicine from The Tamilnadu  Dr MGR Medical University. He is currently pursuing his post graduate course,DM  in medical gastroenterology at  the Madras Medical College Chennai,India.He has published  papers in reputed journals and conducting various research studies.

Abstract:

Introduction: Pneumatic dilation (PD) is considered to be the first line nonsurgical therapy for achalasia. The principle of the procedure is to weaken  the lower  esophageal sphincter by tearing its muscle fibers by generating radial force which is done endoscopically  without fluoroscopic control using  a low-compliance balloon such as  Rigiflex dilator . It has the advantage of determining mucosal injury during the dilation process, so that a repeat endoscopy is not needed to assess the mucosal tearing.

Aim: To study the series of cases of  achalasia  cardia, managed  by pneumatic dilatation and observe their efficacy, outcomes and complications presenting  in our centre during the period of July 2015 to 2017

Methods: 27 cases of achalasia cardia  which presented to our centre during July 2015 to 2017  and  managed by endoscope guided  pneumatic dilatation were retrospectively analysed and their outcomes were observed.

Results: 25 of 27 patients with achalasia presented with dysphagia for solids or liquids. 20 patients had regurgitation and vomiting. Weight loss of more than 5 Kg was observed in 10 patients. History of  nocturnal cough was present in 7 patients. 35 dilatations were performed in 27 patients. All patients had  relief of dysphagia and regurgitation within 24 hours. Barium swallow within a week of dilatation  showed a decrease in the maximum  diameter of the oesophagus from 42.4 + 11.4 mm to 30.5 + 10.5 mm and increase in the diameter of the narrowed lower segment  from 2.45 + 1.5 mm to 11.4+ 2.2 mm. None of the patients  showed a hold up of  barium after dilatation. 20 patients complained of retrosternal  pain during  procedure but none persisted for 24 hours. No perforations were encountered during the study. There was no procedural mortality .

Conclusion: Endoscope-guided PD is an efficient and safe nonsurgical therapy with results comparable to other treatment modalities.

Dr. Thinakarmani has completed his MBBS at 23 years of age from pondicherry university and MD internal medicine from Manipal university (Gold medal with award for best outgoing students ), currently working us senior resident( Final year DM post graduate ) at institute of medical gastroenterology at Madras medical college, chennai, tamilnadu, india. He has presented many papers at national conferences all around India.

Abstract:

Background and Aims

Pancreatic injury remains a complicated condition requiring an individualized case by case approach to management. In this study, we aim to analyze the varied presentations and treatment outcomes of traumatic pancreatic injury in a tertiary care center

Materials and Methods

All consecutive patients hospitalized at our center with traumatic pancreatic injury between 2013 and 2017 were included. The American Association for Surgery of Trauma (AAST) classification was used to stratify patients into five grades of severity. Outcome parameters were then analyzed based on the treatment modality employed.

Results:

Of the 35 patients analyzed, 26 had an underlying blunt trauma with the remaining 9 presenting due to penetrating injury. Overall in-hospital mortality was 28%. 19 of these patients underwent exploratory laparotomy with the remaining 16 managed non-operatively. 9 patients had severe injury ( >grade 3) – of which 4 underwent endotherapy, 3 had stents placed and one underwent an endoscopic pseudocyst drainage. Among those managed non-operatively, 3 underwent a radiological drainage procedure.

Conclusion:

Mortality rates were clearly higher in patients managed operatively. This is likely a result of significantly higher degrees of major associated non-pancreatic injuries and not just a reflection of surgical morbidity. Despite this, surgical management remains the mainstay of therapy, especially in higher grades of pancreatic injury. However we would like to emphasize that endoscopic intervention definitely remains the preferred treatment modality when the clinical setting permits.

This is especially applicable in cases of main pancreatic duct injury with ascites as well as pseudocysts.

Abstract:

Background: Sigmoid volvulus is a very rare condition causing intestinal obstruction in pregnancy associated with extremely high rate of morbidity and mortality for both mother and fetus, early diagnosis based on clinical judgment and use of modern imaging modalities are required for achieving better results and avoiding any surgical intervention. Case report: We report the case of a 23-week pregnant lady, present with severe abdominal distention and constipation, diagnosis was achieved using magnetic resonance image, emergency flexible sigmoidoscopy with detorsion of volvulus done successfully with no complication to the mother or fetus, she was maintained on stool softener and remained well on follow-up. Discussion: We have reviewed the available literature on this topic, as of 2017, less than 100 cases had been reported since first reported case in 1885, most of them ended by surgical resection of gangrenous part of the colon and the need for colostomy. One case had been managed by endoscopy is reported in Brunei. Sigmoid volvulus is the most cause of intestinal obstruction during pregnancy accounting for up to 44% of reported cases. Delay in diagnosis usually goes back to similarity between common gastro-enteric symptoms in pregnancy that can mask truly obstructive one, and also hesitate in use of radiologic image for evaluation.

Conclusions: Effective management represents a challenge, as a delayed presentation and diagnosis will lead to catastrophic feto-maternal complications. A high incidence of clinical suspicion and timely intervention are the key to a favourable outcome.

Abstract:

Introduction

Portal vein thrombosis(PVT) has become an increasingly recognisable disorder during evaluation of cases of abdominal pain with usage of widespread imaging techniques.PVT can result due to various clinical conditions like Chronic liver disease,Infections,malignancies and hypercoagulable states. The objective of this study is to observe the clinical presentation and to do the etiological work up of cases of PVT in a tertiary care centre.This can aid in early diagnosis and expert intervention thereby reducing the morbidity in cases of PVT.

Patients and Methods

The study is a cross- sectional observational study done on patients having PVT,who presented to Institute of Medical Gastroenterology,MMC & RGGGH,during the period of Jan 2016 - July 2017were taken up for the study.The clinical presentation of the above patients were observed and their etiological work up done.

Results

Totally 45 cases were taken into study.

27 were males and 18 were females.

Clinical presentation--The main symptoms were,abdominal distension(18 patients,51%),abdominal pain(10 patients,27%) pain associated with diarrhoea and vomiting(5 patients,14%) pain with nausea and anorexia(3 patients,8%).

Etiological work up showed—Chronic liver disease(24 patients,54%)prothrombotic states(9 patients,20%) local factors,prothrombotic risks and idiopathic causes(12 patients,26%).

Detection of PVT were done mostly by Portal vein Doppler(32 patients,72%) computed tomography(13 patients,27%).

Conclusions

Higher incidence of PVT were seen among patients with chronic liver disease.Prothrombotic  states like myeloproliferative disorders and coagulation defects were the next common causes detected.PVT presenting as plain abdominal pain, pain associated with nausea, vomiting and diarrhoea  were seen in patients as well,thereby suggesting that PVT is an important differential diagnosis in patients presenting as abdominal pain with a negative work up for common causes.With the help of widespread and improved Imaging techniques,earlier diagnosis of PVT can be achieved  and early intervention can greatly reduce the morbidity of patients.

Sibithooran K has completed his under-graduation from Sri Devaraj Urs Medical College, Kolar and his Masters in Internal Medicine from the Manipal University. He is currently a Resident of Gastroenterology at Madras Medical College, Chennai.

Abstract:

Aims: To retrospectively analyze the indications and the success rates of the ERCP procedures done for pancreatic diseases in our tertiary care center.

Materials & Methods: All the patients who underwent ERCP procedure for pancreatic diseases during August 2015 to July 2017 were included in the study and the details were analyzed.

Results: A total of 83 patients underwent ERCP for pancreatic diseases. The indications were symptomatic pancreatic pseudocysts (21), symptomatic pancreatic duct strictures in CCP (17), Intra ductal calculi (15), Pancreatic ductal leak with pancreatic ascites (12), pancreatic divisum with F/O CCP (11) and Traumatic pancreatitis (7). About 15 Patients of Pseudocysts, 14 with pancreatic ductal strictures, 9 with intra ductal calculi, 8 with pancreatic duct leaks eventually required surgical intervention either due to failed procedure or persistent symptoms. However, among the 18 patients who had pancreatic divisum and traumatic pancreatitis only two ended up requiring surgical intervention with 16 of them being successfully treated with ERCP.

Discussion: ERCP’s main benefit is the minimally invasive nature in the management of pancreatic and biliary diseases. However, the complex nature of the technique demands a long learning curve. ERCP is done increasingly for pancreatic diseases in our centre and the results are very encouraging especially pancreatic divisum and traumatic pancreatitis where the cure rate approaches 90%. There is a 66% cure rate among the patients who have pancreatic ductal leaks with pancreatic ascites. Among the other indications for ERCP in pancreatic diseases the cure rates are less than 40% and most of them required a surgery at the end.

Conclusion: ERCP proved to be an effective minimally invasive technique among patients who had pancreatic divisum and traumatic pancreatitis.

Hameed Ur Rehman Habib Ur Rehman, a core medical trainee working in Gastroenterology department at Chesterfield Royal Hospital in East Midlands,  UK. 

Abstract:

We report a case of a 59-year-old male, with no past medical history and foreign travel, who presented with a 1 week history of left arm weakness and numbness followed by an inability to contract his biceps for duration of 48 hours. These symptoms occurred after eating Pork Ribs at a local restaurant 2 weeks ago. On presentation, he was jaundiced and his liver function tests demonstrated a hepatitis-like picture. He had a positive hepatitis E PCR result. His diagnosis was brachial neuritis secondary to acute hepatitis E infection. Viral hepatitis E infection has been reported in 10% of patients with brachial neuritis. According to the most recent case report, an article published in April 2017 in the Journal of NeuroVirology, only 9 such cases have been reported in the UK. We therefore possibly reported the 10th case of hepatitis E associated brachial neuritis in the UK in a non-immunocompromised patient without any past medical history. This case again reminds us to consider hepatitis E infection in a patient presenting with neurological signs and deranged liver function tests.

Dr. Pujarini Dash is working as a SERB NPDF Post-Doc Fellow in tumor microenvironment and animal models lab, Institute of Life Sciences, Bhubaneswar, India, under the mentorship of Dr. Shantibhusan Senapati. She is primarily investigating the role of CAFs’ secretome in pancreatic cancer.

Abstract:

Macrophage migration inhibitory factor (MIF) is a cytokine having multiple functions in different types of cancers including pancreatic cancer (PC). Induced expression of MIF in PC tissue and its high expression in PDAC-derived exosomes provide strong rationale to investigate its association with PC. Cancer associated fibroblasts (CAFs), the major population of tumor microenvironment, are known to play crucial role in PC growth, progression and survival. The objectives of this study were to investigate the expression status of MIF and its receptors in CAFs and how their level of expression gets regulated in presence of inflammatory stimuli. To explore the secretome of human CAFs, a global proteomic profiling was carried out which showed that CAFs express MIF. To check the expression status of MIF and its receptors in CAFs in clinical scenario, CAFs were isolated from PC tissue of cancer patients through outgrowth method. Expression analysis of MIF and its receptors in CAFs (through qPCR, Western blot, immunofluorescence and FACS) and also in PC tissues in situ (through immunohistochemistry) show that CAFs express MIF. As inflammation is a contributing factor to MIF production and also has effect on PC, we further checked the expression of MIF and its receptors in CAFs following stimulation with LPS and TNF-a through qPCR, which showed that these inflammatory stimuli up-regulated the expression of both MIF and its receptors. Our ongoing work will shed light on the role of MIF in CAF’s pathophysiology, which may open up possibilities for targeted therapeutic strategies for PC.

Mohammed  Noufal B has completed his MBBS and MD internal medicine from The Tamilnadu  Dr MGR Medical University. He is currently pursuing his post graduate course,DM  in medical gastroenterology at  the Madras Medical College Chennai,India.He has published  papers in reputed journals and conducting various research studies.

Abstract:

Introduction: Pneumatic dilation (PD) is considered to be the first line nonsurgical therapy for achalasia. The principle of the procedure is to weaken  the lower  esophageal sphincter by tearing its muscle fibers by generating radial force which is done endoscopically  without fluoroscopic control using  a low-compliance balloon such as  Rigiflex dilator . It has the advantage of determining mucosal injury during the dilation process, so that a repeat endoscopy is not needed to assess the mucosal tearing.

Aim: To study the series of cases of  achalasia  cardia, managed  by pneumatic dilatation and observe their efficacy, outcomes and complications presenting  in our centre during the period of July 2015 to 2017

Methods: 27 cases of achalasia cardia  which presented to our centre during July 2015 to 2017  and  managed by endoscope guided  pneumatic dilatation were retrospectively analysed and their outcomes were observed.

Results: 25 of 27 patients with achalasia presented with dysphagia for solids or liquids. 20 patients had regurgitation and vomiting. Weight loss of more than 5 Kg was observed in 10 patients. History of  nocturnal cough was present in 7 patients. 35 dilatations were performed in 27 patients. All patients had  relief of dysphagia and regurgitation within 24 hours. Barium swallow within a week of dilatation  showed a decrease in the maximum  diameter of the oesophagus from 42.4 + 11.4 mm to 30.5 + 10.5 mm and increase in the diameter of the narrowed lower segment  from 2.45 + 1.5 mm to 11.4+ 2.2 mm. None of the patients  showed a hold up of  barium after dilatation. 20 patients complained of retrosternal  pain during  procedure but none persisted for 24 hours. No perforations were encountered during the study. There was no procedural mortality .

Conclusions: Endoscope-guided PD is an efficient and safe nonsurgical therapy with results comparable to other treatment modalities.

Abstract:

Background and Aims

The liver is integral to lipid metabolism and a compromise in its function leads to perturbations in these pathways. In this study we hope to determine the correlation between CLD severity and its effect on lipid parameters. We also look at the etiology specific effects on lipid levels.

Materials and Methods

This is a retrospective cross sectional analysis of 250 patients with cirrhosis compared to 250 healthy age and sex matched controls. Severity assessment of CLD using MELD and Child-Pugh scores was performed and etiological details collected. A questionnaire was used to obtain patient demographic details and lastly a fasting lipid profile (Total, LDL, HDL cholesterol, Triglycerides and VLDL) was obtained.

Results

All components of the lipid profile declined linearly with increasing severity of CLD as determined by MELD and Child-Pugh scores. Lipid levels were clearly lower in CLD patients as compared to healthy controls. Interestingly, preliminary analysis indicated that CLD of different etiologies had differential effects on Lipid profiles – This aspect is under further analysis.

Conclusions

All components of the lipid profile were definitely lower in CLD patients as compared to controls and demonstrated an inverse correlation with increasing severity. The utilization of this parameter as a prognosticating aid requires further study. Additionally preliminary analysis indicates that various CLD etiologies appear to have specific effects on the lipid profile – a finding under further analysis.

Title: An overview of potential pathophysiological mechanisms in food hypersensitivity

Time : 12:00-13:00

Speaker
Biography:

Gülen Arslan Lied is a consultant gastroenterologist and professor at the Haukeland University Hospital, Department of Gastroenterology in Bergen, Norway. She has engaged in active research since 2001 and she supervises many PhD candidates and master students in field of gastroenterology and human and clinical nutrition. Her fields of interests include clinical trials in interactions between nutrition and gut microbiota, inflammation, functional gastrointestinal disorders (irritable bowel syndrome) including nutritional and allergo-immunological aspects, food allergy and intolerance (food hypersensitivity), and experimental studies (food allergy model in mice and colitis models induced by DSS or TNBS in rats).

Abstract:

Majority of the patients with perceived food hypersensitivity have irritable bowel syndrome (IBS), and a significant proportion of IBS patients also attribute their gastrointestinal complaints to food items. Different factors such as disturbed intestinal fermentation, enteric dysmotility, post-infectious changes and altered microbial flora in the colon as well as psychological disturbances likely play a role in the pathophysiology and symptoms generation in patients with food hypersensitivity. The management of these patients should be interdisciplinary.

The results of our more than 10 years’ interdisciplinary research program dealing with such patients showed that food allergy was seldom diagnosed despite extensive examinations. The majority of the patients fulfilled the diagnostic criteria for irritable bowel syndrome. In addition, most suffered from several extraintestinal health complaints and had considerably impaired quality of life. However, psychological factors could explain only approximately 10% of the variance in the patients’ symptom severity and 90% of the variance thus remained unexplained. Intolerance to low-digestible carbohydrates was a common problem and abdominal symptoms were replicated by carbohydrate ingestion. A considerable number of patients showed evidence of immune activation by analyses of B-cell activating factor, dendritic cells and “IgE-armed” mast cells. In addition, a number of other studies in these patient groups indicate that local, systemic and mucosal immune systems are activated. During the presentation, the role of these potential factors including management of these patients will be  reported in patients with perceived food hypersensitivity.

Abstract:

Gastric volvulus is an uncommon condition. It occurs mainly as a result of congenital laxity of the stomach's attachments and might be accompanied by a diaphragmatic hernia. This sometimes causes the stomach to herniate into the thorax. It can be mesentricoaxial or organoaxial, former being rarer. We present our 2 patients who were managed with minimal invasive surgery. We managed two patients with gastric volvulus, both had mesentricoaxial gastric volvulus. One of the patient also had diaphragmatic hernia in which repair was done with mesh hernioplasty. Both patients recovered well from surgery. The average hospital stay was 3 days. Mesentricoaxial gastric volvulus is a rare disease and very few cases have been reported in the literature and there are combined endoscopic and laparoscopic approaches for treatment. In secondary volvulus, the diaphragmatic defect has to be repaired, preferably with mesh. Gastropexy is performed in all cases. Even though worldwide experience in laparoscopic surgery for gastric volvulus is limited, the results are encouraging. Based on our experience, laparoscopic management seems to be safe and feasible in the rare case of mesentricoaxial gastric volvulus.
