Direct visualization of biliary stump polyp in a boy with recurrent pancreatitis after surgery for pancreatobiliary maljunction associated with choledocal cyst

Area of Science:

• Gastroenterology and Hepatology
• Surgical Endoscopy

Background:

• Pancreatobiliary maljunction (PBM) is a congenital anomaly with potential for biliary and pancreatic duct complications.
• Accurate diagnosis and assessment of PBM are crucial for appropriate management.

Purpose of the Study:

• To demonstrate the utility of direct cholangioscopy in evaluating patients with pancreatobiliary maljunction.
• To visualize the junctional anatomy and identify any associated pathological changes.

Main Methods:

• Direct cholangioscopy was performed in patients diagnosed with pancreatobiliary maljunction.
• The procedure involved cannulation of the bile duct and insertion of a small endoscope for direct visualization.

Main Results:

• Direct visualization of the pancreatobiliary junction was achieved.
• The technique allowed for detailed assessment of the common channel and biliary/pancreatic ductal anatomy.
• Potential findings such as reflux or mucosal abnormalities could be identified.

Conclusions:

• Direct cholangioscopy provides a unique and detailed view of the pancreatobiliary junction in PBM.
• This endoscopic approach can complement other imaging modalities for comprehensive evaluation and treatment planning in PBM patients.
