Anterior colon resection

The operation often involves the sigmoid colon, upper rectum or both. Surgeons may use the term anterior resection rather than anterior colon resection, so the operative plan is the clearest guide to the exact segment involved.

The surgeon removes the affected bowel with nearby tissue selected for the condition being treated. The bowel ends may then be joined in an anastomosis. Some people need a temporary or lasting stoma, where bowel is brought to an opening on the abdomen for waste to enter a bag.

The procedure may be open or performed through smaller abdominal incisions. Its extent depends on the abnormality's location, previous surgery, bowel health and whether nearby structures are involved.

Before admission, confirm the instructions for eating, drinking, bowel preparation and regular medicines. Tell the surgical team about blood-thinning medicines, diabetes treatment, allergies, smoking, previous abdominal operations and any new illness.

After surgery, the care plan may include pain relief, breathing exercises, gradual movement and a staged return to food. Follow wound and stoma instructions, avoid straining beyond the team's limits, and record changes in bowel function that you want to discuss at follow-up.

Call the surgical team promptly for increasing abdominal pain or swelling, fever, repeated vomiting, a wound that becomes red or drains fluid, inability to keep fluids down, or an unexpected reduction in stoma output.

Seek urgent care for sudden breathing difficulty, chest pain, fainting, heavy bleeding, a rigid or severely painful abdomen, or rapidly worsening illness. Use the discharge contact provided by the hospital when the concern is related to the recent operation.

Ask which bowel segment will be removed, whether nearby lymph nodes or organs are part of the plan, how the bowel will be rejoined, and under what circumstances a stoma might be needed. Clarify how pathology findings could affect further treatment and when normal activities can resume.
