Impact of Prolonged Operative Time on Minimally Invasive Colorectal Surgery Outcomes

Prolonged operative time was found to be associated with longer length of stay and higher probability of complications in minimally invasive colorectal surgery. However, the negative impact of prolonged operative time on outcomes was less pronounced in minimally invasive approaches compared to open surgery. Each additional hour of operative time above the median for a given operation was associated with a relative risk of longer length of stay for both open and minimally invasive approaches.
