Comparison of Different Endoscopic Methods Used for Managing Choledocholithiasis in Patients with End-Stage Renal Disease Undergoing Hemodialysis.

Background And Aim: Endoscopic sphincterotomy (EST), endoscopic papillary balloon dilation (EPBD), and endoscopic sphincterotomy plus balloon dilation (ESBD) are all techniques used to manage choledocholithiasis. We aim to analyze the efficacy and safety of these techniques for treating choledocholithiasis in patients undergoing hemodialysis (HD).

Methods: We performed a retrospective study of 80 patients with end-stage renal disease (ESRD) on HD who underwent endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis management between August 1st, 2012, and December 31st, 2020, at a medical center in southern Taiwan. These patients were divided into three groups: EST (n = 21), EPBD (n = 28), and ESBD (n = 31). Post-ERCP complications, including pancreatitis, bleeding, cholangitis, and perforation, were reviewed for analysis.

Results: There were no significant among-group differences in the rate of complete stone clearance and hospitalization day after ERCP. Patients in the EST group had a higher post-ERCP complication rate than was the case in the other groups (p = 0.016). ESBD significantly reduced post-ERCP bleeding, compared with that occurring with EST (OR 0.07; 95% CI, 0.01-0.72, p = 0.026). There were no significant among-group differences in the rates of pancreatitis and cholangitis. There were no ERCP-related perforations or deaths in this study.

Conclusions: EST, EPBD, and ESBD are efficient methods for treating choledocholithiasis in ESRD patients. ESBD was found to lead to a lower risk of bleeding than EST, and the rate of pancreatitis or cholangitis was comparable for EST and EPBD. Our results suggest that ESBD is the best choice of treatment of choledocholithiasis in patients with ESRD undergoing HD.
