Background and Aims The option for performing ERCP and laparoscopic cholecystectomy (LC) for the management of choledocholithiasis in the same operative session is often overlooked. We compared the success, safety, and cost of ERCP and LC when performed in either a single session or in separate sessions. Methods We conducted a retrospective cohort study at a U.S. tertiary care hospital. We identified patients undergoing ERCP and LC between April 2011 and August 2014 in either a single operative session (n = 33) or in 2 separate sessions within a 30-day period (n = 80). Technical success, total anesthesia duration, operative time, length of hospitalization, cost of care, and morbidity and mortality were evaluated. Results Bile duct clearance was achieved in all patients at ERCP in the same-session cohort. The separate versus single-session groups, respectively, did not differ in terms of total procedure times (mean ± SD = 142 ± 64 vs 142 ± 58 min; t test, P =.98), anesthesia duration (251 ± 64 vs 225 ± 69 min; P =.06), or overall cost (49.3 ± 24.5 vs 42.3 ± 23.2 ×1000 USD; P =.167), but hospitalization was longer in the separate-sessions group (6.2 ± 3.3 vs 4.8 ± 2.6 days; P =.03). The rates of adverse events were similarly low (7% vs 2%, P =.70). Conclusions Performing single-session ERCP and LC is safe, effective, economically viable, and reduces hospital stay compared with performing ERCP and LC during separate sessions.
