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

BACKGROUNDIntraductal 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, with morphological variations and occasional invasion.CASE SUMMARYWe present a patient with obstructive jaundice who was diagnosed with IPNB using cholangioscopy during endoscopic retrograde cholangio-pancreatography. Using the SpyGlass DS II technology, we were able to define tumor extension and obtain targeted Spy-byte biopsies. After multidisciplinary evaluation, the patient was scheduled for surgical resection of the tumor, which was radically removed.CONCLUSIONCholangioscopy appears to be crucial for the rapid and clear diagnosis of lesions in the bile duct to achieve radical surgical resection.
