Objective  To investigate the risk factors for delayed discharge following same-day choledochoscopic lithotomy for residual stones after biliary tract surgery. Methods  The clinical data of 607 patients with residual stone after biliary tract surgery admitted to the Day Surgery Center of West China Hospital of Sichuan University between July 2019 and July 2022 were retrospectively collected. According to whether the patients were discharged on the same day, they were divided into same-day discharge group and delayed discharge group. The differences in gender, age, first surgical procedure (surgical method, hepatectomy or not, intraoperative choledochoscopy or not), choledochoscopic lithotomy (first choledochoscopy or not, lithotomy method, number of stones and site of stones), operation duration, hospital stay, hospital cost, and postoperative complications (fever, poor drainage, and T tube dislodgement) between the two groups were compared and analyzed. Multiple logistic regression model was used to analyze the risk factors for delayed discharge following same-day choledochoscopic lithotomy. Results  All patients were admitted and discharged within 24 h, among them, 557 cases (91.8%) were discharged on the same day and 50 cases (8.2%) were discharged the next day. The results of multiple logistic regression analysis showed that choledochoscopy for the first time [odds ratio (OR)=2.359, 95% confidence interval (CI) (1.303, 4.273), P=0.005], lithotomy after electrohydraulic lithotripsy [OR=1.857, 95%CI (1.013, 3.402), P=0.045], and multiple stones (number of stones ≥2) [OR=2.741, 95%CI (1.194, 6.288), P=0.017] were independent risk factors for delayed discharge. Conclusion  The operation of same-day choledochoscopic lithotomy is mature, and choledochoscopy for the first time, lithotomy after electrohydraulic lithotripsy, and multiple stones (number of stones ≥2) are independent risk factors for delayed discharge.
