Clinical Outcomes of Single Operator Endoscopic Biliary Interventions: An Analysis of Indications, Technical Success, and Safety in a Consecutive Case Series

ABSTRACT Background: Endoscopic biliary intervention, predominantly ERCP, is a core therapeutic modality for pancreatobiliary disorders, but outcomes remain dependent on indication selection, imaging, operator experience, and institutional support. Methods: This retrospective consecutive case series analyzed 112 patients undergoing endoscopic biliary intervention by a single operator. Demographic profile, indications, biochemical parameters, pre-procedural imaging, technical success, procedural outcomes, and immediate complications were assessed. Results: The mean age was 54.1 +/- 17.1 years, and 70 patients (62.5%) were male. The commonest indication was combined cholelithiasis and choledocholithiasis (30.4%), followed by isolated choledocholithiasis (14.3%). MRCP or CT was available before intervention in 87.5% of patients. Technical success was achieved in 105 of 112 procedures (93.8%). The most frequent procedural outcomes were stent placement for drainage (54.5%) and CBD clearance with stenting (30.4%). No immediate post-procedural complications were documented. Conclusion: Single-operator endoscopic biliary intervention achieved high technical success and excellent immediate safety in a mixed tertiary-care caseload. Prospective multicenter studies with standardized quality indicators and delayed adverse-event follow-up are required to validate these findings.
