PURPOSE Recently, cholangioscopy using narrow band imaging (NBI) has been used as a diagnostic modality for better visualization in hepatobiliary malignancies; however, there are few reports on it. Our aim is to evaluate the effectiveness of cholangioscopy using NBI in hepatobiliary malignancies. METHODS Between January 2007 and December 2016, 152 cholangioscopies using percutaneous approach ...

Intrahepatic lithiasis is a rare condition in Western countries, and the majority of reported cases to date have been associated with extrahepatic biliary tract gallstones and hereditary cystic disorders, such as Caroli disease. The usual clinical presentation consists of repeated episodes of cholangitis, which can be complicated by liver abscess and sepsis. The management of intrahepatic galls...

Clearance of a difficult biliary stone can be obtained using various interventional techniques such as endoscopic sphincterotomy followed by papillary large balloon dilation, mechanical lithotripsy, peroral cholangioscopy-assisted intraductal electrohydraulic/laser temporary plastic stent insertion, percutaneous transhepatic cholangioscopy-guided and extracorporeal shock wave lithotripsy. We he...

Aim. To demonstrate our own experience of performing transfistula cholangioscopy and removing bile duct stones. Materials Methods. From 2017 to 2019, 230 patients with functioning external biliary drains underwent antegrade cholangioscopy. Preliminary dilatation straightening the fistulous tract were required in 37 patients. Results. Bile stones detected 158 (68.7%) During cholangioscopy, remov...

Ninety percent of patients with intraductal biliary stones are successfully treated with sphincterotomy and subsequent stone extraction. However, technical difficulty increases with stone size and giant stones require fragmenation to facilitate endoscopic removal. For stones too large to be engaged in a basket for mechanical lithotripsy laser and electrohydraulic lithotripsy have been proposed ...

Postoperative biliary stricture is a relatively rare but serious complication of biliary surgery. Although Rouxen-Y hepaticojejunostomy or choledochojejunostomy are well-established and fundamental therapeutic approaches, their postoperative morbidity and mortality rates have been reported to be up to 33% and 13%, respectively. Recent studies suggest that percutaneous transhepatic intervention ...

Endoscopy is the first-line therapy for most post-liver transplantation anastomotic biliary strictures. Passage of a guidewire through the stricture is done under fluoroscopic guidance. Although anastomotic biliary strictures are usually short, they can be tight, fibrotic, and angulated, sometimes not allowing guidewire passage. Additional interventions (percutaneous transhepatic cholangiograph...

Conventionally, choledocholithiasis is managed by endoscopic retrograde cholangiopancreatography (ERCP), and it accounts for at least 50% of the approximately 52000 ERCPs performed in the UK each year [1–5]. Bile duct stone clearance traditionally involves the performance of ERCP with biliary sphincterotomy (or sphincteroplasty), followed by the removal of stones from the biliary tree using an ...
