Il Sang Shin et al. Comparison of disposable digital single-operator cholangioscopy versus direct peroral cholangioscopy for the diagnosis of intraductal superficial lesions of the bile duct
Disposable digital single-operator cholangioscopy (D-SOC) and direct peroral cholangioscopy (D-POC) using an ultraslim endoscope were compared in this study, which included 38 patients with suspected biliary disease. D-SOC had a higher technical success rate than D-POC (100% vs. 92.1%), without statistical significance, and a significantly shorter procedure duration (11 vs. 19 minutes). Conversely, D-POC had a marginally higher superficial lesion detection rate (34.2% vs. 28.9%) and higher visualization quality (P = 0.03).
