What to expect from rectal cancer surgery for rectal cancer

The surgeon removes the rectal tumour with a margin of nearby tissue and may assess nearby lymph nodes. The remaining bowel may be connected to the lower rectum or anus. If that join needs protection while it heals, a loop stoma may divert stool through an opening in the abdomen; the surgical team explains whether reversal may be considered.

After surgery, bowel habits can change. You may have urgency, frequent small bowel movements, loose stool, constipation or difficulty controlling gas. A stoma nurse can teach pouch care, skin protection and signs of leakage. Recovery also includes managing the incision, regaining movement and gradually returning to food.

Before admission, ask which medicines to take, when to stop eating or drinking, and whether bowel preparation is required. Arrange help with meals, transport and lifting after discharge. In hospital, follow the walking, breathing and wound-care instructions; increase activity gradually and avoid heavy lifting until cleared.

Eat and drink according to the surgical team’s plan. Record bowel movements, stoma output if present, pain and temperature. A dietitian or continence specialist can help if food triggers urgency or stool remains difficult to manage. Attend pathology and follow-up appointments so the next treatment decisions can be discussed.

Contact the surgical team promptly for increasing abdominal pain, repeated vomiting, a swollen abdomen, worsening wound redness, pus, or a stoma that changes colour. Seek urgent care for heavy bleeding, fainting, breathing difficulty, or inability to pass stool or gas with worsening pain.

Ask what operation is planned, whether a stoma is likely, how bowel function may change, and which activities are restricted at home. Clarify wound care, pain medicines, pathology timing, follow-up, and the number to call for urgent concerns.
