ABSTRACT
BACKGROUND: The use of nonradiation endoscopic retrograde cholangiopancreatography (NR-ERCP) for choledocholithiasis is still limited. Hereby, we introduced our experience of digital cholangioscopy (DCS)-assisted NR-ERCP for retrieval of common bile duct stones.
METHODS: Altogether, data of 132 patients who underwent DCS-assisted NR-ERCP for choledocholithiasis were collected. Procedure details, complications, and short-term follow-up were reviewed and analyzed and were compared with those of conventional endoscopic retrograde cholangiopancreatography (ERCP).
RESULTS: Routine stone extraction and laser lithotripsy were planned in 116 and 16 patients, respectively. Biliary access was successfully achieved by standard biliary cannulation and by advanced techniques in 99 and 33 patients, respectively. Complete stone removal was achieved in a single session in all patients. Routine stone extraction was performed in 117 patients, and laser lithotripsy was applied in 15 patients, among whom 14 patients with planned lithotripsy and 1 unexpected impacted stone found during the procedure. Unexpected right localized intrahepatic stones and purulent cholecystitis were found in 1 and 3 patients, respectively. Three mild and 1 moderate pancreatitis, 5 cases of hyperamylasemia, and 2 cases of leukocytosis occurred as complications. Short-term follow-up revealed no stone residual. Procedure details, technical success, and complications were not statistically different than conventional ERCP.
CONCLUSIONS: DCS-assisted NR-ERCP is technically feasible, efficient, and safe for retrieval of common bile duct stones. This novel method is superior to conventional ERCP on detecting unexpected concomitant biliary diseases.
