MIS for Gastrointestinal Conditions

Colon Resection

Each year more than 600,000 surgical procedures for colon diseases are performed in the United States. Today, many colon surgeries can be completed with a minimally invasive surgery (MIS) approach. The vast majority of surgeries performed on the colon are for cancer, diverticulitis, Crohn's disease and colitis.

In 1990, LifeBridge Health's Dr. Peter Geis became one of the first surgeons in the nation to perform a minimally invasive colon resection.

In most laparoscopic colon resections, surgeons repair and/or remove portions of a patient's colon through small openings in the abdomen while watching an enlarged image of the patient's internal organs on a television monitor. Depending on the length and complexity of the procedure, patients usually leave the hospital in a few days and return to normal activities more quickly than patients recovering from open surgery.


MIS is also being used for fecal diversion with the creation of an ileostomy, an opening between the surface of the skin and the small intestine, and a colostomy, an opening between the surface of the skin and the colon. Fecal diversions are often used to treat complex rectal or anal problems and poor control of bowels (incontinence). If a patient has had an ileostomy or colostomy that must be closed, MIS may be used to easily reverse and close the ileostomy or colostomy with a very short hospitalization.

Other Procedures

Other common gastrointestinal MIS procedures include small bowel resection, appendectomy/cecectomy and various procedures on the stomach.
