Dilated common bile duct is commonly associated with main duct Intraductal Papillary Mucinous Neoplasm of the pancreas

BMC Gastroenterology, 2023
Background Dilatation of common bile duct (CBD) is mostly pathological and mainly occurs secondary to mechanical causes. We aimed to explore the prevalence of CBD dilatation in Intraductal Papillary Mucinous Neoplasms of the pancreas (IPMN) among ...

Neuroendocrine Tumor of the Common Bile Duct: Case Report

Case Reports in Oncology, 2021
Carcinoma of the extrahepatic biliary tract accounts for <2% of all cancers. Neuroendocrine tumor of the extrahepatic bile duct is very rare, and there are <200 cases reported since 1959. The preoperative diagnosis is infrequent (5.12%).

Common bile duct lesions - how cholangioscopy helps rule out intraductal papillary neoplasms of the bile duct: A case report

World Journal of Gastrointestinal Endoscopy, 2020
BACKGROUND Intraductal papillary neoplasm of the bile duct (IPNB) is a rare variant of bile duct tumors, characterized by an exophytic growth exhibiting a papillary mass within the bile duct lumen and it can be localized anywhere along the biliary tree ...

Direct peroral cholangioscopy with red dichromatic imaging 3 detected the perihilar margin of superficial papillary extension in a patient with intraductal papillary neoplasm of the bile duct

DEN Open, 2023
Intraductal papillary neoplasms of the bile duct (IPNB) are a tumor derived from bile duct epithelium that tends to spread laterally and non‐invasively. Surgery is the first‐choice treatment for IPNB.

Surgical Treatment of Intraductal Papillary Neoplasm of the Bile Duct: A Report of Two Cases and Review of the Literature

Frontiers in Oncology, 2022
Intraductal papillary neoplasm of the bile duct (IPNB) is a rare bile duct tumor characterized by intraductal papillary or villous neoplasms covered by neoplastic epithelium with fine fibrovascular stalks in the dilated bile ducts (1).

An impossible biliary drainage? Fistulization of a degenerated intraductal papillary mucinous pancreatic neoplasm to the common bile duct

Endoscopy, 2022
Intraductal papillary mucinous pancreatic neoplasms (IPMNs) are very common lesions. International guidelines recommend surveillance or more invasive management according to precise criteria [1].

Poorly Cohesive Carcinoma of Common Bile Duct: A Rare Histological Type of Cholangiocarcinoma

Clinical Medicine Insights: Case Reports
Biliary tract carcinomas (BTC) are malignant epithelial neoplasms subdivided anatomically into: gallbladder carcinomas and carcinomas of the bile duct or cholangiocarcinomas (CCA); including intrahepatic, hilar/perihilar, and distal CCA.

Intraductal papillary neoplasms of the bile duct: stepwise progression to carcinoma involves common molecular pathways [PDF]

Modern Pathology, 2014
Intraductal papillary neoplasms of the bile duct are still poorly characterized regarding (1) their molecular alterations during the development to invasive carcinomas, (2) their subtype stratification and (3) their biological behavior. We performed a multicenter study that analyzed these issues in a large European cohort.

A rare case of resection of a mucinous cystic neoplasm originating from the extrahepatic bile duct with cholangioscopic imaging

DEN Open
A 29‐year‐old woman was admitted to our hospital for examination of obstructive jaundice and an extrahepatic bile duct lesion. Contrast‐enhanced computed tomography revealed a 20 mm cystic lesion with a thin external capsule in the common hepatic duct ...
