a 65-year-old female presenting with hepatobiliary cystadenoma (hc) comprised of multiple cysts in the liver and a non-specific epigastric pain is reported herein.  ultrasound study demonstrated dilated common bile duct (cbd) and intrahepatic bile ducts, plus two spherical stone-like bodies filling defects in the proximal cbd. sphincterotomy and basket performed for the patient were not success...

are rare, and occur when there is bile stasis and a nidus for stone conglomeration [1,2]. Endoscopic examination of the bile duct has traditionally been difficult and is not routinely performed. We report the first case of management of recurrent bile duct stones using an ultrathin upper endoscope. A 54-year-old woman presented for endoscopic retrograde cholangiography (ERC) for removal of bili...

A double or accessory common bile duct (ACBD) is a rare congenital anomaly. We report the case of a 60-year-old American Asian male, who was found to have a double or duplicated common bile duct after being admitted for evaluation of a pancreatic mass. A duplicated bile duct has the same mucosa histologically as a single bile duct. However, the opening of a duplicated bile duct lacks a sphincte...

BACKGROUND AND STUDY AIMS Endoscopic sphincterotomy (EST) is effective, but recurrent bile duct stones are a common late complication. Because there are still no effective therapies for preventing this complication, some patients have experienced bile duct stone recurrence many times. We describe herein a method of abdominal massage to treat patients with prior cholecystectomy who have experien...

A 32-year-old male, a known case of alcohol related chronic non calcific pancreatitis, was referred to us for pancreatic endotherapy for relief of intractable abdominal pain. The cross sectional imaging studies had revealed an irregularly dilated main pancreatic duct. The examination of the major duodenal papilla revealed the presence of two separate orifices at endoscopic retrograde cholangiop...

Laparoscopic cholecystectomy is now a gold standard treatment modality for gallstone diseases. However, the incidence rate of bile duct injury has not been changed for many years. From initial classification published by Bismuth, there have been many classifications of common bile duct injury. The initial classification, levels and types of bile duct injury, and currently combined vascular inju...

The patient was a 70-year-old male whose chief complaints were obstructive jaundice and weight loss. Abdominal imaging studies showed a 2.5 cm sized mass at the distal common bile duct, which was suggestive of bile duct cancer. Eccentric enhancing wall thickening in the transverse colon was also shown, suggesting concomitant colon cancer. A colonoscopy revealed a lumen-encircling ulcerofungatin...

CONTEXT In our previous pancreatic cancer mouse models, we have used surgical orthotopic implantation of human pancreatic tumors to establish clinically relevant fluorescent mouse models of pancreatic cancer. OBJECTIVE Since exocrine pancreatic cancer is thought to arise from the cells lining the ducts of the pancreas, we hypothesized that direct injection of tumor cells into the common bile ...

Motor activity of the sphincter of Oddi has been evaluated in 34 patients who underwent ERCP examination. Manometric recordings from the common bile duct and the sphincter of Oddi were performed with a polyethylene triple lumen catheter. At ERCP 16 patients had undamaged biliary ducts; six had undergone cholecystectomy and six had gall bladder stones; 18 patients had common bile duct stones; ni...

Introduction: Ascariasis by Ascaris lumbricoides is a cosmopolitan disease. Biliary ascariasis is unusual in our country. We report a case of biliary ascariasis revealed by biliary colic. Observation: A 22-year-old woman with no particular history was received for biliary colic associated to vomiting without fever or bowel disorders. On examination, there were pain and defense at the right uppe...
