Outcome of surgical treatment for recurrence of biliary stones

Abstract

Background: Cholelithiasis is one of the most common digestive disease, a chronic recurrent hepatobiliary disease whose pathological bases are impaired cholesterol, bilirubin and bile acid metabolism. Management of recurrent biliary stones is difficult because of the precense of deepseated intrahepatic ductal stones and ductal strictures, which are often multiple. Purpose: The objective of this study is to evaluate the efficacy and safety of surgical treatment for recurrence of biliary stone patients. Patients and Methods: Prospective analyses of the patients of recurrent biliary stones (common bile duct and intrahepatic) at Department of GI Surgery, Hue Univesity of Medicine and Pharmacy Hospital and Department of GI Surgery, Hue Central Hospital from 01/2019 to 06/2022. We evaluated the data according to outcome measures, characteristics and treatment results of recurrent cholelithiasis patients. Results: 52 patients were included into the study, mean age of the patients was 53.6±16.5 years. 44 patients (84.6%) had previous choledocholithotomy and T tube drainage during 24 months. Common bile duct stones were 69.2%, intrahepatic gallstones were 65.4%. Type of surgery included: choledocholithotomy and T tube drainage were 55.8%, left hepatectomy plus drainage were 32.6%. There was no operative mortality. Complication occurred in 13.4% of patients and half the complications involved wound ìnfection. With regard to residual stones after operation by cholangiography, there are 6 patients obviously showed residual gallstones. Follow-up examination during 3-6 months showed 90.1% of patients with good results. Conclusion: Surgical management of recurrent biliary stones (common bile duct and intrahepatic) were safe and effective. Key words: Gallstones, residual gallstones, relapse gallstone.
