Primary biliary stones: diagnosis and management

Area of Science:

• Gastroenterology
• Hepatobiliary Surgery
• Diagnostic Imaging

Background:

• Primary biliary stones pose significant clinical challenges, often presenting with acute cholangitis or abdominal pain.
• A history of biliary surgery is common in patients with primary biliary stones, indicating complex disease progression.
• Diagnosis frequently involves multiple imaging modalities, including endoscopic retrograde cholangiopancreatography (ERCP), ultrasonography, and computed tomography (CT).

Purpose of the Study:

• To retrospectively review the treatment outcomes for primary biliary stones.
• To evaluate the efficacy of a systematic and aggressive management strategy for primary biliary stones.

Main Methods:

• Retrospective analysis of 96 patients managed between 1991 and 1996.
• Utilized diagnostic tools such as ERCP, ultrasonography, and CT.
• Employed surgical interventions including hepatic resection and intraoperative choledochoscopy.
• Constructed hepaticocutaneous jejunostomy (HCJ) for postoperative management.

Main Results:

• Intrahepatic stones were present in 95% of patients; 35% had biliary strictures.
• 16% of patients had concomitant cholangiocarcinoma.
• Hepatic resection was performed in 57% of cases; 73% had HCJ constructed.
• Postoperative choledochoscopic extraction successfully eradicated residual stones in 23% of patients.
• Morbidity was 29%, with one hospital death (cholangiocarcinoma patient).
• Stone recurrence was observed in only three patients during follow-up.

Conclusions:

• An aggressive, systematic treatment approach for primary biliary stones yields satisfactory early results.
• Key components of the successful strategy include hepatic resection, HCJ construction, and postoperative choledochoscopy.
• Complete eradication of biliary stones is achievable with this comprehensive management plan.
