Surgery for bowel cancer takes about two hours, and with anesthesia and recovery time, it may take about three hours. Bowel cancer surgery is now a relatively routine surgery, usually performed laparoscopically, which is a minimally invasive surgical treatment method, or some units may choose robotic surgery. Overall, bowel cancer surgery does not take long, usually about two hours to complete. However, anesthesia is needed before the surgery, and anesthesia recovery is needed after the surgery, so both of them may take about three hours combined. In addition, after the surgery, most patients return to the ward in a conscious state.
