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...

Aviation-related mechanism may exist in the post-cholecystectomy syndrome (PCS) of aircrew patients. The aim of this study was to test this hypothesis on vivo rabbit model and to explore the mechanism by using a novel telemetric method. We constructed a bile duct-to-intestinal bridge bypass on 30 rabbits, with a telemetry implant attached to the Oddi's sphincter. Then a telemetric recording sys...

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 ...
