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...

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...

Glucagon is well acknowledged as a sphincter of Oddi relaxant for both diagnostic and therapeutic uses in choledocholithiasis, and an empiric treatment for β-blocker overdose. Although it has been implicated in inducing cardiovascular crises in patients with asymptomatic pheochromocytoma, adverse effects in other patient populations have not been characterized. This case report describes a patient with hypertension controlled on β blockers who, after glucagon administration during an intraoperative cholangiography, experienced hypertensive emergency despite adequate pain control...

BACKGROUND: Postoperative pancreatic fistula represents the most important complication after distal pancreatectomy. The aim of this study was to evaluate the use of a preoperative endoscopic injection of botulinum toxin into the sphincter of Oddi to prevent postoperative pancreatic fistula (German Clinical Trials Register number: DRKS00007885). METHODS: This was an investigator-initiated, prospective clinical phase I/II trial with an exploratory study design. We included patients who underwent preoperative endoscopic sphincter botulinum toxin injection (100 units of Botox)...

Dysfunction of the sphincter of Oddi is a rare disease that causes about 20% of recurrent idiopathic pancreatitis. In order to suspect its existence, it is mandatory to have ruled out all other causes of acute pancreatitis. Then, the disease needs to be classified by degree of dysfunction and have a manometry performed as it is considered the gold standard of diagnosis. Manometry is used to guide treatment and its method of choice is usually an endoscopic sphincterotomy. In this article a case of recurrent pancreatitis is discussed, which after a thorough study that ruled out other etiologies, was diagnosed as a pancreatic-type dysfunction of the sphincter of Oddi...

INTRODUCTION: The most common cause of gas under diaphragm is hollow viscous perforation. In 10% of cases it can be due to rare causes, both abdominal and extra-abdominal, one of them being intra abdominal infection by gas forming organisms. PRESENTATION OF THE CASE: A 51 year old male patient, a poorly controlled diabetic, presented with a second episode of severe pain abdomen and abdominal distention, with lower abdominal tenderness. Plain Xray of the abdomen in erect posture showed gas under the right dome of diaphragm and ultrasound abdomen confirmed gross pneumoperitoneum...

Post-cholecystectomy syndrome and the concept of a causal relationship to sphincter of Oddi dysfunction, despite the controversy, has presented a clinically relevant conflict for decades. Historically surgeons, and now gastroenterologists have expended tremendous efforts towards trying to better understand the dilemma that is confounded by unique patient phenotypes. Areas covered: This review encompasses the literature from a century of experience on the topic of post-cholecystectomy syndrome. Relevant historical and anecdotal experiences are examined in the setting of insights from evaluation of recently available controlled data...

Background Acute pancreatitis is the most common complication after ERCP, occurring in about 4 % of the procedures. Only the placement of pancreatic duct prosthesis and the use of nonsteroidal anti-inflammatory drugs (NSAIDs) have shown benefit in the prevention of post-ERCP pancreatitis (PEP). Although the benefit of rectal administration of indomethacin or diclofenac is recommended by some studies and society guidelines especially in a selected group of high-risk patients, there is so far, no standardization of time or route of NSAID administration...

BACKGROUND: Relaxing the sphincter of Oddi (SO) is an important process during endoscopic retrograde cholangiopancreatography (ERCP) procedures. This issue suggests that the easier the sphincterotomy and cannulation, the more post-ERCP complications decrease. AIMS: To compare the relaxant effects of ataciguat (a novel soluble guanylyl cyclase activator) and zaprinast (an inhibitor of phosphodiesterase 5) on sheep SO in vitro, thus testing whether they can be used during ERCP...
