BACKGROUND: 10% of patients who undergo a cholecystectomy go on to develop post-cholecystectomy syndrome (PCS). The majority of these patients may suffer from extra-biliary or unrelated organic disorders that may have been present before cholecystectomy. The numerous aetiological causes of PCS result in a wide spectrum of management options, each with varying success in abating symptoms. This systematic review aims to provide a summary of the causative aetiologies of post cholecystectomy syndrome, their incidences and efficacy of available management options...

A novel type of interstitial tissue cells in the biliary tree termed telocytes (TCs), formerly known as interstitial Cajal-like cells (ICLCs), exhibits very particular features which unequivocally distinguish these cells from interstitial cells of Cajal (ICCs) and other interstitial cell types. Current research substantiates the existence of TCs and ICCs in the biliary system (gallbladder, extrahepatic bile duct, cystic duct, common bile duct and sphincter of Oddi). Here, we review the distribution, morphology and ultrastructure of TCs and ICCs in the biliary tree, with emphasis on their presumptive roles in physiological and pathophysiological processes...

Backgrounds/Aims: Postcholecystectomy syndrome represents a heterogeneous group of symptoms and findings in patients who have previously undergone cholecystectomy. It is rare and under-reported in Saudi Arabia. It can be attributed to many complications such as bile duct injury, biliary leak, retained common bile duct stones, recurrent bile duct stones, and bile duct strictures. In this study, we aimed to analyze the causes and evaluate the approach to postcholecystectomy syndrome in our local Saudi Arabian community because of the vast number of cases encountered in our hospital for gallbladder clinical conditions and its related complications...

BACKGROUND AND OBJECTIVES: Prophylactic antibiotics are frequently administered for transarterial chemoembolization (TACE) of hepatocellular carcinoma (HCC). In patients without previous biliary instrumentation, infection risk from TACE is low. We hypothesized that there is a negligible rate of infection in these patients without prophylactic antibiotics. METHODS: We reviewed consecutive patients undergoing TACE between 7/1/2013-6/15/2016. All patients had an intact Sphincter of Oddi, received no peri-procedural antibiotics, and had 30+ days follow-up...

BACKGROUND: Whether preserving sphincter of Oddi (SO) function by endoscopic papillary balloon dilation (EPBD) is beneficial for preventing recurrent common bile duct stone disease (CBDS) is controversial. The aim of this study was to measure sphincter of Oddi (SO) function by using SO manometry, and to evaluate the association with recurrent CBDS. METHODS: Patients with suspected CBDS who underwent successful EPBD were included. These patients underwent SO manometry at two months after EPBD with bile duct clearance...

INTRODUCTION: Although measuring the pressure of the sphincter of Oddi and the bile duct is considered to be an important examination, called Sphincter of Oddi manometry (SOM), some complications related to the SOM device remain unsolved. MATERIAL AND METHODS: To decrease adverse complications, we developed a 0.46 mm manometry and we performed some in vitro studies. RESULTS: We successfully developed a 0.46 mm SOM. The diameter is the thinnest size used in endoscopic examinations...

In this review article important and frequently used investigation methods for gastrointestinal functional diagnostics are presented. Some other rarely used special investigations are also explained. The hydrogen breath test is simple to carry out, ubiquitously available and enables the detection of lactose, fructose and sorbitol malabsorption. Furthermore, by the application of glucose, the test can be carried out when there is a suspicion of abnormal intestinal bacterial colonization and using lactulose for measuring small intestinal transit time...

Post-endoscopic pancreatitis (PEP) is the most common complication of endoscopic retrograde cholangiopancreatography (ERCP). Depending on the presence of risk factors, PEP can occur in 4,1% to about 43% of patients. According to the European Society of Gastrointestinal Endoscopy (ESGE) guidelines, only three to patient-associated risk factors have been identified: suspected sphincter of Oddi dysfunction (SOD) (OR 4.09), female gender (OR 2.23), and previous pancreatitis (OR 2.46). Another three procedure-associated factors include cannulation attempt duration > 10 minutes (OR 1...

Irritable bowel syndrome (IBS) is the most common gastrointestinal (GI) disorder worldwide, however treatment options for diarrhea-predominant IBS (IBS-D) remain limited. Eluxadoline, a µ- and κ-opioid receptor agonist and δ-opioid receptor antagonist, was recently approved for the treatment of IBS-D. A novel compound first described in 2008, eluxadoline was shown to normalize GI transit, with a subsequent phase I demonstrating its safety and tolerability in healthy adults. In 2016, two randomized, double-blind, placebo-controlled phase III trials studying eluxadoline use at 75 mg and 100 mg twice daily over 26 weeks demonstrated a significant improvement in stool consistency and many global symptoms of IBS...

Clinically, acupuncture affects the motility of the extrahepatic biliary tract, but the underlining mechanisms are still unknown. We applied manual acupuncture (MA) and electrical acupuncture (EA) separately at acupoints Tianshu (ST25), Qimen (LR14), Yanglingquan (GB34), and Yidan (CO11) in forty guinea pigs (4 groups) with or without atropinization under anesthesia while Sphincter of Oddi (SO) myoelectric activities and gallbladder pressure were monitored. In both MA and EA groups, stimulation at ST25 or LR14 significantly increased the frequency and amplitude of SO myoelectrical activities and simultaneously decreased the gallbladder pressure as compared to the pre-MA and pre-EA (P < 0...

Recurrent bile duct stones is the most common complication after gallstone surgery and the incidence is about 4-24%. Sphincter of Oddi laxity will lead to duodenal content flow into the bile or pancreatic duct. Patients with recurrent bile duct stones and Oddis sphincter laxity were intractable. Here we sought to present the possible and helpful surgical treatments for such patients. Prospective randomized clinical trial are needed for evaluating the outcome of surgical treatments.

OBJECTIVE: Suspected sphincter of Oddi dysfunction (SOD) is a well-known risk factor for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP). The indication of ERCP for suspected SOD patients was very low in Japan compared to other countries. Therefore, the risk of PEP may be different in Japanese SOD patients. The objective of this study was to evaluate the risk of PEP in suspected biliary type SOD in Japan. METHODS: From December 1996 to January 2017, 72 patients were suspected as having biliary type SOD, by questionnaire, liver function tests, hepatobiliary scintigraphy, abdominal ultrasonography, upper gastrointestinal endoscopy, endoscopic ultrasonography and magnetic resonance cholangiopancreatography...

BACKGROUND AND AIMS: Sham procedures in endoscopy are used with the intention of controlling for placebo response, potentially allowing more precise evaluation of treatment effect. Nevertheless, this type of study may impose significant risk without potential benefit for those in the sham group. The aim of the current study was to systematically review and analyze the endoscopic literature to assess the safety of sham controls. METHODS: MEDLINE and Embase databases were searched for endoscopic sham procedures for all dates to July 2017...

Pancreaticobiliary maljunction is a congenital malformation in which the pancreatic and bile ducts join outside the duodenal wall, usually forming a long common channel. Because the action of the sphincter of Oddi does not regulate the function of the pancreaticobiliary junction in patients with pancreaticobiliary maljunction, two-way regurgitation occurs. Reflux of pancreatic juice into the biliary tract is associated with a high incidence of biliary cancer. Biliary carcinogenesis in patients with pancreaticobiliary maljunction is thought to follow the hyperplasia, dysplasia, then carcinoma sequence due to chronic inflammation caused by pancreatobiliary reflux...

Cholecystokinin (CCK) is an important neuro-intestinal peptide hormone produced by the enteroendocrine I-cells in the upper part of small intestine. Protein- and fat-enriched food plays an important role in triggering CCK secretion from the intestine. Carbohydrates stimulate only small amounts of CCK release. The CCK-1 receptor (CCK-1R) is largely localized in the gallbladder, sphincter of Oddi, pancreas, small intestine, gastric mucosa, and pyloric sphincter, where it is responsible for CCK to regulate multiple digestive processes including gallbladder contraction, pancreatic secretion, small intestinal transit, and gastric emptying...
