Laparoscopic Training Opportunities in an Emergency Biliary Service.

Background And Objectives: Optimizing single-session management of biliary emergencies whilst maximizing laparoscopic training opportunities is challenging. We analyzed training opportunities available in an emergency biliary department and its impact on service provision and patient outcomes.

Methods: A single surgeon's practice of 2049 emergency laparoscopic cholecystectomies and common bile duct explorations was prospectively analyzed. Training involved a modular stepwise approach incorporating access, gallbladder bed dissection, pedicle dissection, intra- corporeal tying, and cholangiogram ± common bile duct exploration. Training cases were identified, trainee involvement ascertained, and parameters predictive of a training case were established.

Results: Thirty percent of laparoscopic cholecystectomies were performed in part or completely by trainees, with a training component in 30% of bile duct explorations. Trainee involvement increased mean operating time by approximately 10 minutes. There was no difference in minor (5% vs 5%, = .8) or major complications (1% vs 0.9%, = .7) on trainee versus consultant cases. Postoperative hospital stay was greater in consultant cases (2.87 vs 4.44 days, = .0025).Multivariate analysis identified predictors of trainee cases including lower age (OR, 1.3; 95% CI, 1.1-1.7), female sex (OR, 1.6; 95% CI, 1.3-2), normal-weight subjects (OR, 1.54; 95% CI, 1.3-1.9), lower difficulty grade (1-2) (OR, 1.8; 95% CI, 1.4-2.2), and American Society of Anesthesiologists score ≤ 2 (OR, 1.8; 95% CI, 1.4-2.4).

Conclusions: Surgical training is possible in a singlesession biliary emergency service without significantly impacting theatre utilization times or early patient outcomes. Further dedicated studies will allow individual learning curves to be determined.
