Objective:
To investigate the safety and efficacy of ERCP combined with single-operator cholangioscopy (SOC) for the management of common bile duct stones and transpapillary gallbladder polyps.
Methods:
In this retrospective case series, we analyzed 10 patients with common bile duct (CBD) stones and gallbladder polyps who were treated with ERCP combined with SOC between May 2022 and September 2024. The technical and clinical success rates, polyp resection rate, methods of cystic duct cannulation, total procedure time, polyp resection time, and the complication rate were recorded and analyzed.
Results:
Both the technical success rate and the clinical success rate of SOC-guided gallbladder polyp removal were 100%. Among the 10 patients, gallbladder access was achieved using guidewire-assisted SOC in 3 patients and direct SOC entry into the cystic duct in 7 patients. The mean overall procedure time was 53.0 ± 14.2 min, and the mean polyp resection time was 20.80 ± 11.02 min. The diameter of the polyps ranged from 2 to 8 mm. Pathological examination revealed 5 inflammatory polyps, 1 adenomatous polyp, and 4 cholesterol polyps. No intraoperative or postoperative complications occurred. During a follow-up period of 3 to 28 months, no recurrence of gallbladder polyps was observed.
Conclusion:
Transpapillary gallbladder polyp resection using ERCP combined with SOC represents a minimally invasive technique that appears to be technically feasible and safe. This approach has the potential for broader clinical adoption.
