BACKGROUND: This study aimed to evaluate the outcomes and complications of secondary hepatolithiasis following choledochoenterostomy to guide suitable management.
METHODS: The study analyzed 127 patients from a 2017 national survey conducted by the Ministry of Health, Labor, and Welfare. The 2023 cohort study assessed residual stones, recurrences, cholangitis, cholangiocarcinoma, and prognosis.
RESULTS: The median follow-up duration was 48 months. Balloon endoscopy-assisted endoscopic retrograde cholangiography (BE-ERC) was the most common treatment, achieving complete stone clearance in 84.4% of patients. Anatomical hepatectomy was the most common surgery. Predictors of residual stones were stone number ≥10 (odds ratio [OR], 7.480; p = .028) and stone diameter ≥10 mm (OR, 5.280; p = .020). Predictors of stone recurrence during follow-up were biliary strictures (hazard ratio [HR], 3.580; p = .005) and cholangitis (HR, 2.700; p = .037). Predictors of cholangitis during follow-up were biliary stricture (HR, 5.016; p = .006) and dilatation (HR, 3.560; p = .029). Any treatment for hepatolithiasis reduced cholangitis occurrence (HR, 0.168; p = .042). Balloon dilation combined with stenting for ≥3 months improved biliary strictures in 57.1% of patients.
CONCLUSION: This study recommends BE-ERC as the first-choice treatment for secondary hepatolithiasis. Stone removal and relief of biliary strictures and dilatation are crucial to prevent stone recurrence and cholangitis after treatment.
