A multi-center retrospective chart review of short-term outcomes associated with robotic-assisted cholecystectomies performed during regular hours and after-hours.
The study is a retrospective multi-center chart review study of short-term patient outcomes through 30 days after robotic-assisted cholecystectomies performed during regular hours and after-hours. The primary outcomes include the rate of conversion to open, rate of intra-operative adverse events, the rate of post-operative adverse events relating to the cholecystectomy within 30 days, and re-admissions and re-operations relating to the cholecystectomy within 30 days. In addition, operative time, the rate of use of intra-operative imaging, and the hospital length of stay will be collected as secondary outcomes.
