Inclusion criteria
Inclusion criteria: Patients in whom common bile duct stones were identified on pre-procedural imaging (computed tomography, magnetic resonance cholangiopancreatography, ultrasonography, endoscopic ultrasonography, or balloon enteroscopy-assisted ERCP) and who were considered to require endoscopic stone removal. Patients with surgically altered anatomy (excluding Billroth I reconstruction). Patients with a distal bile duct diameter >=8 mm. Patients with a modified American Society of Anesthesiologists physical status (mASA-PS) classification of II or lower. Patients aged >=18 years who provided written informed consent to participate in the study.
Exclusion criteria
Exclusion criteria: Patients in whom discontinuation of antithrombotic agents was considered difficult. Patients with cholangitis, severe jaundice (total bilirubin >5 mg/dL), or pancreatitis. Patients in whom single-session stone removal was considered difficult, including those with stacked stones, stones >15 mm in diameter, Mirizzi syndrome, or concomitant biliary stricture. Patients with a history of pancreatitis following balloon enteroscopy-assisted ERCP (BE-ERCP). Patients who were pregnant or possibly pregnant. Patients who were deemed unsuitable for participation in this study by the principal investigator or sub-investigators for medical or safety reasons.
