BACKGROUND Bile duct stones after hepaticojejunostomy are considered a troublesome adverse event. Although percutaneous transhepatic procedures using a cholangioscopy is performed to treat these bile duct stones, a peroral endoscopic procedure using a short, double-balloon enteroscope (sDBE) is an alternative. This study aimed to compare the immediate and long-term outcomes of both treatments f...

Biliary adenomas that are usually found in surgically removed gallbladders are rare, but can also occur in the extrahepatic biliary tree. We present a case series of extrahepatic bile duct adenomas at our institution, along with a review of the literature. All three patients with extrahepatic biliary adenomas (two in the common bile ducts, one in the hepatic duct) were female with a mean age of...

choledochoduodenostomy (EUS-CDS) is reported with increasing frequency [1]. While stent migration into the bile duct is a possible complication of EUS-CDS, it has not previously been reported. We describe a case of complete stent migration into the bile duct, where the stent was successfully retrieved by inserting an endoscope directly into the bile duct after balloon dilation of the duodenal f...

A 98-year-old woman with a medical history of cholecystectomy (12 years ago), partial gastrectomy (10 years ago), pacemaker implanted, and acute coronary syndrome was admitted to hospital for right upper quadrant colicky pain and moderate cholestasis (AST: 37 IU/L, ALT: 25 IU/L, ALP: 164 IU/L, GGT: 65 IU/L, total bilirubin: 0.7 mg/100). An abdominal ultrasound scan revealed an important dilatat...

Artificial intelligence (AI) research in endoscopy is being translated at rapid pace with a number of approved devices now available for use luminal endoscopy. However, the published literature AI biliopancreatic predominantly limited to early pre-clinical studies including applications diagnostic EUS and patient risk stratification. Potential future cases are highlighted this manuscript optica...

A 75-year-old woman with hypertension presented with acute suppurative cholangitis. Chest radiography revealed severe kyphosis. Abdominal computed tomography revealed a large stone impacted in the common bile duct (CBD). The patient underwent emergent endoscopic retrograde cholangiopancreatography, and cholangiography revealed a large stone (7×3 cm) in the CBD that could not be captured using a...

We describe the histological and histochemical changes of the common bile-duct mucosa in specimens obtained by means of peroral cholangioscopy, 1-12 years after choledochoduodenal anastomosis. Our findings--hyperplasia of the superficial epithelium, metaplastic goblet cells containing predominantly acid sialomucins, and pyloric-like gland formation containing neutral mucins--express a morpholog...

We report a very rare case of benign biliary stricture with calcification and porcelain gallbladder, causing difficulty in differential diagnosis. A 64-year-old man was referred for further examination of jaundice. Computed tomography showed calcifications in the gallbladder wall and the common bile duct. Endoscopic retrograde cholangiopancreatography revealed narrowing and a filling defect in ...

A 73-year-old man with a history of liver transplantation developed cholestasis. No abnormality was seen on magnetic resonance imaging. Percutaneous cholangioscopy via a left-sided transhepatic tract (●" Fig.1) demonstrated carpet-like villous change with biopsies showing highgrade dysplasia in the right and left ducts. Intraductal ultrasound (IDUS) showed a T1 lesion, with bile duct wall thick...

A 34-year-old female with a history of advanced pulmonary sarcoidosis and right-sided heart failure presented with chronic, postprandial right upper quadrant pain, and weight loss. Endoscopic biliary drainage was deemed to be the most appropriate therapeutic option for her chronic cholecystitis. Endoscopic retrograde cholangiopancreatography utilizing the SpyGlass cholangioscopy system allowed ...
