Background: Endoscopic sphincterotomy (ES) is an effective therapeutic procedure for common bile duct (CBD) stone clearance but it carries a substantial risk of recurrent stones at long-term outcome.
Aim of the study: To evaluate the rate of CBD stones recurrence after primary complete endoscopic clearance, and to identify the risk factors of recurrence.
Methods: Between January 2002 and December 2016, 2255 patients with CBD stones who underwent successful ES and complete stone clearance were studied retrospectively. Recurrent CBD stone, was defined by the confirmation of the presence of CBD stone at least 6 months after previous complete CBD stone clearance by ES. The risk factors for recurrent CBD stones and mean time interval between initial ES and stone recurrence were analyzed.
Results: In Total, 2255 patients we included. The median follow up period was 89 (6-187) months. Recurrent CBD stones appeared in 159/2255 (7.05 %) patients after a median time interval of 22 (6-216) months following ES. Stone recurrences were observed on multiple occasions in 20 patients (0.88%). On the univariate analysis, the significant risk factors related to recurrent CBD stone were male sex (P = 0.001), previous history of cholecystectomy (P = 0.001) multiple CBD stones (P = 0.001), large CBD stone (P = 0.001) the presence of periampulary diverticulum (P = 0.001) and stone crushing using mechanical lithotripsy (P = 0.001)
Conclusion: Recurrence of CBD stones is an identified long-term risk after ES and stone clearance.
