Keyur Desai, Joshua D Wermers, Nebiyu Beteselassie
Lemmel syndrome occurs when a duodenal diverticulum causes obstructive jaundice due to a mechanical obstruction of the common bile duct. Additional pathophysiologic processes may also contribute to the development of Lemmel syndrome. These include duodenal diverticula causing dysfunction of the sphincter of Oddi as well as compression of the common bile duct by duodenal diverticula. It is uncommon for duodenal diverticulum to become inflamed. We report the case of a 25-year-old female presenting with unintentional weight loss and fatigue...

Aarthi Rajkumar, Albina Piya
BACKGROUND Gallbladder agenesis (GA) is an extremely rare anatomic anomaly with a reported incidence of less than 0.5%. It is usually asymptomatic, but can present with features of biliary colic and cholecystitis. We present here a case of GA in a patient with recurrent biliary colic.  CASE REPORT A 24-year-old African American woman presented with recurrent episodes of right upper-quadrant abdominal pain. During her first episode, she was found to have elevated transaminases and clinical features of cholecystitis, but ultrasound did not visualize a gallbladder and she was discharged with a diagnosis of biliary colic...

PURPOSE: To determine the outcomes of laparoscopic cholecystectomy as a treatment for biliary dyskinesia in children. METHODS: With ethics approval, a retrospective chart review was performed on children (<21 years) at a single center diagnosed with biliary dyskinesia (defined as gallbladder ejection fraction [EF] <35% and/or pain with cholecystokinin [CCK] on cholescintigraphy, in the absence of gallstones or cholecystitis on ultrasound) and treated with laparoscopic cholecystectomy between March 2010 and February 2016...

BACKGROUND: This series of patients with a history of Roux-en-Y gastric bypass (RYGB) and cholecystectomy presented with symptoms consistent with obstructive biliary disease and massive biliary dilation of ≥15 mm, suggesting a structural cause. Findings from laparoscopic-assisted transgastric (TG) ERCP were a normal-appearing ampulla without structural lesions or stones, suggesting a functional cause instead. STUDY DESIGN: Patients who underwent TGERCP from January 2008 to October 2016 and had a surgical history of RYGB and cholecystectomy were identified from an institutional database...

REVIEW
J Tack, D A Drossman
The functional gastrointestinal disorders (FGIDs) are the most common disorders seen in Gastroenterology clinical practice. The Rome process has generated consensus definitions of FGIDS, allowing to subdivide patients into diagnostic categories based on the symptom pattern. The Rome IV consensus, presented in 2016, is the most recent update of this diagnostic scheme. This article summarizes the main changes, which include the use of epidemiology-based symptom thresholds to define FGIDs, characterization of FGIDS as disorders of Gut-Brain interaction, and updates of criteria for esophageal disorders, irritable bowel syndrome and Biliary and Sphincter of Oddi disorders based on scientific and technical progress made over the last decade...

Irritable bowel syndrome (IBS) is a prevalent functional gastrointestinal disorder which represents a major cost to healthcare services. IBS-D patients represent about one-third of the IBS population and are currently treated with antispasmodics, loperamide, bile acid sequestrants and antidepressants. Alosetron and rifaximin are also available in USA, ramosetron in Japan, Korea and Thailand and ondansetron as an off-label treatment. Areas covered: This article focuses on eluxadoline, a novel pharmacological agent that has recently been approved by both the FDA and EMA for treatment of patients with IBS-D...

Pancreaticobiliary maljunction (PBM) is a congenital malformation in which the pancreatic and bile ducts join anatomically outside the duodenal wall, usually forming an abnormally long common channel. In PBM, since the long common channel defeats the effect of the sphincter of Oddi, pancreatobiliary reflux frequently occurs, resulting in high rates of biliary tract cancers. We present the case of a 68-year-old female with advanced gallbladder cancer concomitant with bile duct cancer associated with PBM without biliary dilatation that had an extremely rare configuration showing a connecting duct without a long common channel...

INTRODUCTION: Duodenal gangliocytic paragangliomas are rare neoplasms often arising in proximity to the major duodenal papilla of Vater. These neoplasms are considered to have a benign behavior with lymph node metastases being a rare phenomenon and distant metastatic disease even more so. Resection of the tumor is the only definitive therapy. PRESENTATION OF CASE: A 67year old male presented to a referring hospital with symptoms of fatigue and malaise. Evaluation with CT imaging revealed a 3...

The sphincter of Oddi (SO) is a smooth muscle valve regulating the flow of biliary and pancreatic secretions into the duodenum, initially described in 1887 by the Italian anatomist, Ruggero Oddi. SO dysfunction (SOD) is a broad term referring to numerous biliary, pancreatic, and hepatic disorders resulting from spasms, strictures, and relaxation of this valve at inappropriate times. This review brings attention to various factors that may increase the risk of SOD, including but not limited to: cholecystectomy, opiates, and alcohol...

Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most widely used pharmacological prevention strategy for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP).(1,2) Experimental data suggest that NSAIDs, a group of inhibitors of PTGS1 (cyclooxygenase-1 or COX-1) and PTGS2 (cyclooxygenase-2 or COX-2), can prevent PEP through inhibition of phospholipase A2 which plays a key role in triggering inflammatory response in the pancreas.(3) Given accumulating evidence from clinical trials, peri-procedural use of rectal NSAIDs is considered as an established strategy for prevention of PEP, at least for patients who have risk factors for PEP including younger age, suspected sphincter of Oddi dysfunction as an indication, and a history of pancreatitis...

This study aimed to investigate the expression and function of BKCa channels in the Sphincter of Oddi (SO) in a rabbit model of hypercholesterolemia (HC). New Zealand white rabbits were randomly divided into 2 groups: the control group was fed standard chow (n = 18) whereas the high-cholesterol group was fed cholesterol-enriched chow containing 1.5% cholesterol (n = 18). The serum cholesterol level was significantly greater in the HC groups than in the control group, but there was no significant difference in body weight between the control and HC groups...

Sphincter of Oddi dysfunction is caused by stenosis or dyskinesia of the sphincter of Oddi, leading to blockage of bile drainage from the common bile duct. We present the case of a 16-year-old female with chronic abdominal pain who underwent laparoscopic cholecystectomy for cholelithiasis but continued to experience abdominal pain, nausea, and vomiting along with persistently elevated ALT and AST levels. Postoperative abdominal ultrasound was nondiagnostic. Esophagogastroduodenoscopy showed mild reflux esophagitis and mild chronic Helicobacter pylori-negative gastritis...

BACKGROUND AND AIMS: Biopsy of the ampulla of Vater may be performed to evaluate for ampullary adenomas, suspected ampullary tumors and immunohistological staining for autoimmune pancreatitis. Ampullary biopsies are commonly performed at the time of endoscopic retrograde cholangiopancreatography (ERCP). Due to the well-established complication rate following ERCP, the contribution of ampullary biopsy as a potential independent risk factor would require a controlled comparison. METHODS: A matched-pairs, case-control analysis was performed for patients undergoing ERCP with or without ampullary biopsy...

Liver function assessment by hepatocyte-specific contrast-enhanced magnetic resonance imaging is becoming a new biomarker. Liver function can be assessed by T1 mapping (reduction rate) and signal intensity measurement (relative enhancement ratio) before and after GD-EOB-DTPA (gadoxetic acid) administration, as alternative to Tc-99m galactosyl serum albumin scintigraphy, 99m Tc-labeled mebrofenin scintigraphy, and indocyanine green clearance test. Magnetic resonance imaging assessment of liver function can enable diagnosis of cirrhosis, nonalcoholic fatty liver disease associated fibrosis and steatohepatitis, primary sclerosing cholangitis, toxic hepatitis, and chemotherapy and radiotherapy-related changes, which may be only visible on hepatobiliary phase images...

Acute pancreatitis (AP) is a potentially serious disease whose incidence is on the increase. Pancreas divisum does not meet the required criteria to be considered an aetiological factor. Sphincter of Oddi dysfunction may be another cause of idiopathic AP. Less invasive methods cannot replace Sphincter of Oddi manometry in diagnosis. Almost half of patients with systemic inflammatory response syndrome develop organ failure, but the mechanisms involved are not completely understood. Obesity is a risk factor for severity in AP; the cause could be the presence of free unsaturated fatty acids, which have pro-inflammatory activity...
