Colon surgery problems that can occur include the following: damage to the spleen, perforation of the stomach and/or intestines, injury to the bladder and the connecting tubes, injury to the internal female organs (including the uterus and ovaries), unexpected difficulties resulting in a temporary or permanent colostomy, hernias through the incision, or abdominal wall disruption or breakdown that would require additional surgery.

It is important to discuss possible complications with your surgeon prior to your operation.²²

Complications of open surgery can include muscle stripping, organ failure, blood clotting, or injury to blood vessels.

Because of the larger incision, patients undergoing open surgery require a longer recovery period.²²

It is important to choose a surgeon who has advanced training in laparoscopic techniques. Complications of a minimally invasive procedure can include bleeding, a leak where the colon was reconnected, injury to or perforation of organs (such as the small intestine, ureter, or bladder), injury to blood vessels, a blood clot in the lung, trocar injuries, or infection.

It is possible that a surgeon might need to convert from a minimally invasive procedure to an open surgery during the operation. This decision is made by the surgeon and is based on what is best for the patient.²²
