Colon surgery is used to treat several different conditions, and the reason for surgery determines how the operation is planned. Common reasons include colon cancer, large polyps that cannot be safely removed during colonoscopy, repeated or complicated diverticulitis, a blockage, bleeding, and selected inflammatory bowel conditions. This page is retained for general education; colon surgery is not a current Zadeh Surgical service.
What does colon surgery remove?
A colectomy removes part or all of the large intestine, also called the colon. Most operations remove the diseased section along with an appropriate margin of healthy tissue. The surgeon may then reconnect the two healthy ends. That connection is called an anastomosis.
In some situations, the bowel cannot be reconnected safely at the same operation. The surgeon may create an opening on the abdomen, called a colostomy or ileostomy, so waste can leave the body into a pouch. An ostomy may be temporary or permanent depending on the diagnosis and circumstances.
Why might a polyp or cancer require surgery?
Many polyps are removed during colonoscopy. A large or difficult polyp may require surgery when it cannot be completely removed through the colonoscope or when testing suggests cancer. For colon cancer, the operation generally removes the involved portion of colon and nearby lymph nodes. Additional treatment depends on the final stage and pathology results.
When is surgery considered for diverticulitis?
Diverticula are small pouches that can form in the wall of the colon. When a pouch becomes inflamed or infected, the condition is called diverticulitis. Many episodes improve without surgery. An operation may be considered for a blockage, perforation, fistula, repeated attacks that significantly affect quality of life, or a complicated infection that cannot be controlled safely by other means.
Open, laparoscopic, or robotic colectomy
An open colectomy is performed through one larger abdominal incision. Laparoscopic and robotic operations use a camera and instruments through several smaller incisions. The choice depends on the disease, prior operations, body anatomy, urgency, surgeon experience, and whether another procedure is needed at the same time.
A small-incision approach can support recovery in appropriate patients, but the central goals are safe removal of the diseased bowel, a reliable bowel connection when one is created, and treatment that is appropriate for the diagnosis.
What can recovery involve?
Hospital stay and recovery vary substantially. The team monitors pain control, movement, return of bowel function, nutrition, and signs of infection or a problem with the bowel connection. Before surgery, attention to smoking, nutrition, anemia, diabetes, medications, and physical conditioning can reduce avoidable risk.
Symptoms after colon surgery deserve clear instructions.
Contact the treating team for worsening abdominal pain, repeated vomiting, fever, a swollen abdomen, increasing wound redness or drainage, shortness of breath, or other symptoms listed in the discharge instructions.
