INTRODUCTION Pancreas divisum is the most common congenital pancreatic anomaly; occurring in approximately 7.5% of the general population. It is recognized as a potential risk factor for recurrent acute pancreatitis, and possible chronic pancreatitis. Pancreas divisum results from the failure of fusion of the ventral and dorsal ductal system. The hypothesis of our study was that pancreas divisu...

Background: It has been reported that several species of Helicobacter colonize the biliary tract of animals and human, but their participation in hepatobiliary diseases are not established. This study is undertaken to determine if Helicobacter genus members, especially with regard to H. pylori, could be detected in the bile and gallbladder diseases. Methods: Thirty-eight gallbladder tissues and...

BACKGROUND Intraoperative assessment of biliary tract anatomy is relevant for a number of benign and malignant hepatobiliary diseases. During biliary reconstruction, drainage of all relevant bile ducts is imperative to prevent atrophy of undrained segment, cholangitis and secondary biliary cirrhosis. Intraoperative cholangiography, though widely used for intraoperative imaging of the biliary tr...

BACKGROUND Cholangiocarcinomas (CC) as well as gallbladder cancers are relatively rare and intractable diseases. Clinical, pathological, and epidemiological studies on these tumors have been under investigation. The current status and/or topics on biliary tract cancers have been reported in the East West Association of Liver Tumor (EWALT), held in Milano, Italy in 2015. SUMMARY All the author...

The rise of minimally invasive surgical techniques during the past 20 years has been one of the more dramatic developments in modern medicine. Minimally invasive procedures are now widely accepted for treatment of diseases involving many different organ systems. Minimally invasive procedures may be more common and more accepted in the treatment of diseases of the biliary tract than in any other...

BACKGROUND The ras gene family (H-ras, N-ras and K-ras) are oncogenes that mutate frequently in human cancer, specially in tumors of the biliary tract and pancreas. AIM To determine the frequency of K-ras gene codon 12 mutation in pancreatic and biliary tumors. MATERIAL AND METHODS Samples of 35 gallbladder, 15 ampulla of Vater, 10 biliary tract and 9 pancreatic tumors, were analyzed. The t...

Intestinal perforation from a migrated biliary stent is a known complication of endoscopic biliary stent placement. We present a case of stent migration and resultant duodenal perforation after stent placement for a malignant biliary stricture in a 52-year-old woman. We review the current literature on the diagnosis and management of stent migration and intestinal perforation after endoscopic s...
