Abstract:
Objective:To evaluate the efficacy and safety of digital cholangioscopy-assisted non-radiation endoscopic retrograde cholangiopancreatography (ERCP) for common bile duct stones.Methods:Clinical data of patients who underwent digital cholangioscopy-assisted non-radiation ERCP for common bile duct stones from May 2019 to September 2021 were reviewed. The baseline data, the success rate of cannulation, the one-time success rate of endoscopic stone removal, the operation time, total hospital stay, complications, and recurrence of bile duct stones were analyzed.Results:A total of 170 patients were included, and bile duct stones were detected in 156 (91.8%) patients with the long diameter of 7.7±4.1 mm under preoperative imaging examination. Bile duct stones were detected under choledochoscopy and were successfully removed by using digital cholangioscopy through non-radiation ERCP. The success rate of cannulation was 100.0% (170/170) . The one-time success rate of endoscopic stone removal was 96.5% (164/170), and 6 patients (3.5%) received secondary stone removal for large stones (long diameter>30 mm).The time of biliary exploration and whole non-radiation ERCP were 9.6±2.7 min (6-24 min) and 35.9±17.3 min (13-85 min), respectively. The total hospital stay was 6.3±2.2 days (5-10 days). Postoperative pancreatitis occurred in 3 patients (1.8%), all of whom were mild and resolved after symptomatic treatment. No recurrence of bile duct stones was seen in any patient over 1-month postoperative follow-up.Conclusion:Digital cholangioscopy-assisted non-radiation ERCP is safe and effective for common bile duct stones without ray exposure, which is worth of promotion.
