Abstract: Objective To investigate the clinical efficacy of endoscopic retrograde cholangiopancreatography (ERCP) in the treatment of common bile duct (CBD) stones and to analyze the risk factors associated with postoperative stone recurrence, so as to provide evidence for recurrence prevention and optimization of treatment strategies. Methods Clinical data of patients with CBD stones treated by ERCP at the PLA Joint Logistics Support Force No.904 Hospital from January 2022 to December 2024 were retrospectively analyzed. According to whether recurrence of CBD stones occurred during follow-up, patients were divided into a recurrence group (n=16) and a non-recurrence group (n=55). Baseline characteristics, ERCP-related factors, postoperative complications, and short-term outcomes were compared between the two groups, and independent risk factors for postoperative recurrence were explored. Results A total of 71 patients were included, comprising 16 patients in the recurrence group (22.5%) and 55 patients in the non-recurrence group (77.5%). The mean age of the recurrence group was (68.4 ± 9.2) years, which was significantly higher than that of the non-recurrence group[(61.7 ± 10.5) years, P<0.05]. The proportion of patients with diabetes mellitus was 43.8% (7/16) in the recurrence group, higher than 18.2% (10/55) in the non-recurrence group (P<0.05). Regarding ERCP-related factors, the maximum stone diameter in the recurrence group was (1.5 ± 0.4) cm, significantly larger than that in the non-recurrence group[(1.1 ± 0.4) cm, P<0.05]. The proportion of multiple stones was 68.8% (11/16) in the recurrence group, higher than 36.4% (20/55) in the non-recurrence group (P<0.05). The rate of biliary stent placement was 56.3% (9/16) in the recurrence group, compared with 27.3% (15/55) in the non-recurrence group (P<0.05). The postoperative hospital stay was longer in the recurrence group[(9.4±2.1) days] than in the non-recurrence group[(7.6±1.8) days, P<0.05]. On postoperative day 3, ALT[(78.5±21.3) U/L] and TBil[(32.6±8.4) μmol/L] levels in the recurrence group were significantly higher than those in the non-recurrence group[(61.2±18.7) U/L and (24.1±6.9) μmol/L, respectively; P<0.05]. The postoperative residual stone rate was 25.0% (4/16) in the recurrence group, significantly higher than 5.4%(3/55) in the non-recurrence group (P<0.05). The clinical cure rate was 75.0% (12/16) in the recurrence group, lower than 92.7% (51/55) in the non-recurrence group (P<0.05). Multivariate logistic regression analysis demonstrated that age ≥65 years (OR=2.84, 95%CI: 1.12~7.21), diabetes mellitus (OR=3.16, 95%CI: 1.18~8.46), maximum stone diameter ≥1.5 cm (OR=4.02, 95%CI: 1.45~11.18), multiple stones (OR=2.67, 95%CI: 1.01~7.06), and biliary stent placement (OR=2.91, 95%CI: 1.09~7.79) were independent risk factors for postoperative recurrence (P<0.05). Conclusion ERCP is a safe and effective treatment for CBD stones; however, there remains a certain risk of postoperative recurrence. Advanced age, diabetes mellitus, a higher stone burden, and biliary stent placement significantly increase the risk of stone recurrence. Enhanced perioperative management and postoperative follow-up are warranted for high-risk patients to reduce recurrence and improve long-term outcomes.
