Common bile duct strictures associated with chronic pancreatitis

Area of Science:

• Gastroenterology and Hepatology
• Surgical Oncology

Background:

• Chronic pancreatitis frequently leads to common bile duct (CBD) strictures, potentially causing significant hepatobiliary disease.
• Alcohol-related chronic pancreatitis is a common cause of CBD obstruction requiring intervention.
• Biliary tract strictures are an under-recognized complication of chronic pancreatitis, necessitating prompt diagnosis and management.

Purpose of the Study:

• To report on the surgical management of common bile duct (CBD) strictures in patients with chronic pancreatitis.
• To evaluate the efficacy of operative biliary or pancreatobiliary decompression in patients with CBD obstruction.
• To highlight the importance of surgical intervention for biliary strictures to prevent severe hepatobiliary complications.

Main Methods:

• Retrospective review of nine patients with chronic alcohol-related pancreatitis and CBD obstruction undergoing operative decompression.
• Diagnostic imaging included percutaneous transhepatic cholangiography (PTC) and endoscopic retrograde cholangiopancreatography (ERCP) to delineate biliary anatomy.
• Surgical procedures included biliary decompression, pancreatic pseudocyst (PPC) drainage, and pancreatic duct decompression (Peustow procedure).

Main Results:

• All nine patients underwent successful biliary decompression, with eight also receiving simultaneous PPC or pancreatic duct decompression.
• Percutaneous transhepatic cholangiography (PTC) and endoscopic retrograde cholangiopancreatography (ERCP) accurately delineated abnormal CBD anatomy in 89% of cases.
• No perioperative mortality was observed, and all patients reported subjective improvement in symptoms post-surgery.

Conclusions:

• Surgical management of biliary strictures in chronic pancreatitis is effective in relieving obstruction and preventing hepatobiliary complications like cholangitis and secondary biliary cirrhosis.
• Cholangiography (PTC or ERCP) is crucial for diagnosing and characterizing biliary strictures, while percutaneous biopsy confirms hepatic morphology changes.
• Simultaneous treatment of associated pancreatic pathology, such as pseudocysts, can be performed with minimal added morbidity, improving overall patient outcomes.
