Removal of bile duct stones during endoscopic retrograde cholangiopancreatography (ERCP) usually includes papillotomy. Papillotomy is associated with occasional complications and in addition, the longterm sequelae of papillotomy in young patients having laparoscopic cholecystectomy remain unclear. As an alternative to papillotomy, this study prospectively evaluated the efficacy and safety of en...

Intraductal papillary neoplasms of the bile duct (IPNBs) are recognized as a distinct type of biliary tumor. We herein discuss the possible mechanisms underlying the development of multiple tumors in patients with IPNBs through a case presentation and literature review. A 64-year-old woman initially underwent extended right hepatectomy for IPNB in the right hepatic duct. Although the surgical m...

AIM To evaluate the feasibility and reliability of endoscopic transpapillary bile duct biopsy for the diagnosis of biliary strictures. METHODS A total of 360 patients (241 men) who underwent endoscopic retrograde cholangiopancreatography for biliary strictures with biopsy from April 2012 to March 2016 at Tokyo Medical University Hospital were retrospectively reviewed. This study was approved ...

This study aims to review the causes of intrahepatic and extrahepatic bile duct dilatation. Based on review of medical literature, a scientific classification of the causes is proposed. Intrahepatic and extrahepatic bile duct dilatation can be divided into two categories: congenital and acquired. The former includes the five classical Todani’s congenital types. The latter can be sub-classified ...

BACKGROUND Major bile duct injury is the most worrisome complication of cholecystectomy. There is no detailed data about the incidence or treatment-related costs of bile duct injuries in Turkey. We aimed to determine prevalence and therapeutic costs of patients with major biliary duct injuries managed in our department, and further estimate a projection of these parameters at the national level...

The technique of intraductal ultrasonography (IDUS) of the bile duct with a thin-caliber probe and a ropeway system has provided excellent images of the bile duct and periductal structures and is an easy transpapillary approach. In addition, once the guide wire is inserted into the bile duct, IDUS and transpapillary biopsy after endoscopic retrograde cholangiopancreatography can be performed in...

BACKGROUND Laparoscopic exploration of the common bile duct is becoming more popular, although endoscopic sphincterotomy remains the usual treatment for bile duct stones. However, loss of the biliary sphincter causes permanent duodenobiliary reflux, and recurrent stone disease and biliary neoplasia may be a consequence. METHODS A systematic literature review was conducted to compare laparosco...

BACKGROUND/AIMS Bile leakage is an uncommon but serious complication of cholecystectomy. The aim of this study is to evaluate the efficacy of the endoscopic management of bile leakage after cholecystectomy. METHODS A total of 32 patients who underwent endoscopic retrograde cholangiopancreatography (ERCP), because of bile leakage after cholecystectomy, from January 2000 to December 2012 were r...

Cystic dilatation of the common bile duct constitutes a rare congenital malformation prevalent in people of Asian origin with a female predominance. Its classification follows that of Todani. The commonest form, found in 80% of cases, is type I. Common bile duct cysts are often diagnosed in 2 out of 3 cases, during childhood with adult forms often rare. We hereby report the case of a cystic dil...

Common bile duct perforation has been reported in adults after invasive procedures. Spontaneous common bile duct perforation is a rare entity as a cause of acute abdomen in adults. A few cases due to choledocholithiasis have been reported as a cause of spontaneous perforation. We report an adult patient who presented with acute abdomen after spontaneous common bile duct perforation due to unkno...
