Endoscopic diagnosis of intraductal papillary mucinous neoplasm of the bile duct [PDF]

Journal of Hepato-Biliary-Pancreatic Sciences, 2009
AbstractBackground/PurposeIntraductal papillary mucinous neoplasm of the bile duct (IPMN‐B) is considered an uncommon tumor. The purpose of this study was to evaluate the diagnostic utility of endoscopic cholangiography (ERC) with subsequent peroral cholangioscopy (POCS) and/or intraductal ultrasonography (IDUS) for this tumor.MethodsFrom December 1991

Efficacy of Endoscopic Ultrasound‐guided Fine Needle Biopsy With Simplified Macroscopic On‐site Evaluation (With Video)

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Background and Aims With advances in preoperative chemotherapy and comprehensive genomic profiling, endoscopic ultrasound‐guided fine needle biopsy (EUS‐FNB) has become vital for diagnosing pancreatic and peridigestive tract lesions. However, evidence remains limited regarding the performance of new‐generation puncture needles and simplified ...

A huge intraductal papillary mucinous carcinoma of the bile duct treated by right trisectionectomy with caudate lobectomy

World Journal of Surgical Oncology, 2009
Background Because intraductal papillary mucinous neoplasm of the bile duct (IPMN-B) is believed to show a better clinical course than non-papillary biliary neoplasms, it is important to make a precise diagnosis and to perform complete surgical resection.

Intrahepatic and extrahepatic intraductal papillary neoplasms of bile duct [PDF]

Korean Journal of Hepato-Biliary-Pancreatic Surgery, 2013
There has been an increase in the number of reported cases of biliary neoplasm of the hepatobiliary system characterized by markedly dilated and multifocal papillary epithelial lesions of the bile ducts or cystic biliary lesions with or without mucin secretion, and mucinous lesions or tumors, possibly due to recent advances in radiological diagnosis ...

The Importance of the Gel Immersion Method to Successfully Identify the Jejunojejunal Anastomosis Site After Roux‐Y Reconstruction With Double‐Balloon Enteroscopy‐assisted Endoscopic Retrograde Cholangiopancreatography: A Case Report

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT The gel immersion method improves endoscopic visualization by displacing debris and blood with a viscous gel. Although it is commonly used in procedures such as endoscopic mucosal resection and endoscopic submucosal dissection, its use in double‐balloon enteroscopy‐assisted endoscopic retrograde cholangiopancreatography (DBE‐ERCP) has rarely ...

A case of intraductal papillary neoplasm of the bile duct that developed 38 years after choledochoduodenostomy with invasive adenocarcinoma and lymph node metastasis

Surgical Case Reports, 2019
Background Intraductal papillary neoplasm of the bile duct (IPNB) is a bile duct neoplasm characterized as a precursor lesion of cholangiocarcinoma. An invasive component is present in approximately 40 to 80% of reported cases and lymph node metastasis ...

Intrahepatic gallbladder duplication mimicking a hepatic cyst: A case report

SAGE Open Medical Case Reports, 2023
Gallbladder duplication is a rare anomaly of the biliary tree. Implications of misdiagnosis include unwarranted surgery and morbidity such as when liver resections are done suspecting cystic intraductal papillary neoplasm of the bile duct.

Epidemiology and outcome of individuals with intraductal papillary neoplasms of the bile duct

World Journal of Gastrointestinal Oncology, 2023
Intraductal papillary neoplasm of the bile duct (IPNB) is a rare distinct subtype of precursor lesions of biliary carcinoma. IPNB is considered to originate from luminal biliary epithelial cells, typically displays mucin-hypersecretion or a papillary growth pattern, and results in cystic dilatation[1].
