Recurrent pyogenic cholangitis: disease characteristics and patterns of recurrence

Area of Science:

• Gastroenterology and Hepatology
• Surgical Gastroenterology
• Biliary Tract Diseases

Background:

• Recurrent pyogenic cholangitis (RPC) involves repeated biliary infections, stones, and strictures.
• Management focuses on treating infections, clearing obstructions, and preventing bile stasis.
• Treatment options include operative (hepatectomy, biliary drainage) and nonoperative (ERCP, PTC) approaches.

Purpose of the Study:

• To compare the outcomes of operative versus nonoperative management for RPC.
• To evaluate the long-term effectiveness and recurrence patterns of RPC treatments.
• To identify factors influencing treatment failure in RPC patients.

Main Methods:

• Retrospective analysis of 80 consecutive RPC patients.
• Comparison of initial and long-term failure rates between operative and nonoperative groups.
• Multivariate logistic regression to identify significant factors associated with treatment failure.

Main Results:

• Operative treatment showed significantly lower initial (10.2% vs. 32.3%) and long-term (20.4% vs. 61.3%) failure rates.
• Bilaterality of disease and nonoperative treatment were significant predictors of failure (OR: 8.101, P=0.007; OR: 26.843, P=0.001).
• Median time to failure was longer with operative (48 months) versus nonoperative (20 months) management.

Conclusions:

• Operative management, particularly hepatectomy, is a durable and preferred option for long-term RPC resolution.
• Biliary drainage procedures are also effective, while nonoperative treatments offer shorter disease-free intervals.
• Understanding recurrence patterns and disease extent is crucial for optimizing RPC management.
