Extrahepatic Bile Duct Polyps Combiled with Choledocholithiasis: A Report of one Case

Aim: Bile duct polyps is a rare biliary disease, which may lead to bile duct stones and may play an important role in the occurrence and development of cholangiocarcinoma. Calculus of bile duct is a common disease in China and common causes including multiple polyps of the biliary tract and other factors. Therefore, we here to investigate the relationship of both diseases and to summarize some measures to prevent the occurrence of polyps. Method: We here describe a 49-year-old man presented with yellowing of skin and sclera and the pain in the upper abdominal area. We performed exploration of common bile duct + choledocholithotomy and T-tube drainage and polyps were not detected. Result: Yellow staining of skin and sclera reappeared after operation 2 months. The bile duct mucosa was rough and there was amount of black stones under choledochoscopy. Unexpectedly, at the confluence of the right and left hepatic ducts and at the left hepatic duct, there was a sessile polyp respectively. We electrocoagulated the polyps and removed the stones. The biliary tract was flushed with saline on the second day after operation and the total bilirubin was rapidly decreased. Conclusion: Therefore, we think that bile duct polyps and calculus of bile duct may be causality and influence each other, resulting in disturbance of bile duct dynamics and inducing biliary tract diseases
