- Abstract
Background: Nonradiation, digital cholangioscope (DCS)-assisted endoscopic intervention for cholelithiasis has not been widely performed. For this study, we aimed to report the feasibility, efficacy, and safety of an established DCS-guided lithotomy procedure. Methods: Data relating to biliary exploration, stone clearance, adverse events, and follow-up were obtained from 289 patients. The choledocholithiasis-related outcomes via the DCS-guided procedure were subsequently compared to those via conventional endoscopic retrograde cholangiopancreatography (ERCP). Results: Biliary access was achieved in 285 patients. The technical success rate for the exploration of the common bile duct, the cystic stump, the hilar ducts, and secondary radicals was 100%. Moreover, the success rates were 98.4%, 61.7%, and 20.7%, for the exploration of the cystic duct, complete cystic duct, and gallbladder, respectively. Suspicious or confirmed suppurative cholecystitis, cholesterol polyps, and hyperplastic polyps were detected in 42, 23, and 5 patients, respectively. Stone clearance was achieved in one session in 285 (100%), 11 (100%), 13 (100%), 7 (100%), 6 (100%), and 3 (14.3%) patients with choledocholithiasis and hepatolithiasis, cystic duct stump stones, nondiffuse located intrahepatic lithiasis, a single cystic duct stone, a single gallbladder stone, and diffuse located intrahepatic lithiasis, respectively. Complete stone clearance for diffuse intrahepatic lithiasis was achieved in 19 (90.5%) patients, and fractioned re-lithotomy was performed in 16 (76.2%) patients. One patient developed mild acute cholangitis, and 12 developed mild pancreatitis. Stones recurred in one patient. Compared with conventional ERCP, DCS-guided lithotomy has the advantages of clearing difficult-to-treat choledocholithiasis and revealing concomitant biliary lesions, and this technique has fewer complications and a decreased risk of stone recurrence. Conclusions: The technical profile, efficacy, and safety of nonradiation-guided and DCS-guided lithotomy are shown in this study. We provide a feasible modality for the endoscopic removal of cholelithiasis.
