Primary Outcome Measures

Name	Time	Method
Intraoperative time, in minutes, defined as the time from incision to completion of wound closure. Multiple studies have shown that surgeries resulting in complications had longer operative times than those that did not, and higher BMI is correlated with longer operating time, with a 14% increase in the likelihood of complications for every 30 min of additional operating time.[At time of surgery ]
