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.

Enrollment

The regular hours cohort includes cholecystectomies performed during the day shift at the Institution during Monday through Friday, not inclusive of national holidays.
The after hours cohort includes cholecystectomies performed outside of the day shift at the Institution during Monday through Friday, on the weekend, or during a national holiday.
With the patient under general anesthesia, several small incisions are made in the abdomen. Ports are placed, the abdomen is insufflated, and the da Vinci Robotic Surgical System (Intuitive) is docked to the patient and used to complete the cholecystectomy according to the surgeon's standard of care.

Conversion to open
The rate of conversion of the cholecystectomy to open, defined as robotic-assisted surgery converted to an open approach.
Time frame: Intra-operative
Number of adverse events
Intra-operative or post-operative adverse events related to the cholecystectomy
Time frame: Intra-operative through the 30 day follow-up period
Re-admissions
Re-admissions to the hospital related to the cholecystectomy through the 30 day follow-up period
Time frame: After discharge from the hospital post-procedure through the 30 day follow-up period
Re-operations
Re-operations related to the cholecystectomy through the 30 day follow-up period
Time frame: After the procedure but prior to discharge, through the 30 day follow-up period
Operative time
Operative time, defined as first incision to closure of the incision
Time frame: Intra-operative
Use of intra-operative imaging
The rate of use of intra-operative imaging, including indocyanine green fluorescent imaging and cholangiography
Time frame: Intra-operative
Length of Hospital Stay (LOS)
How long the patient was admitted to the hospital
Time frame: From admission to discharge, up to approximately one week
