What should you know about open bowel resection?

The surgeon removes the affected segment and nearby tissue when needed, then examines the specimen to guide diagnosis and further care. The operation may be considered for bowel cancer, a blockage, bleeding, inflammation or another structural problem. The exact extent depends on the location of disease and the condition of the remaining bowel.

A stoma brings bowel contents through an opening in the abdominal wall into a bag. It may be temporary or long term, depending on healing and the operation. [Bowel Resection](/treatments/surgical-oncology/colectomy/) describes the procedure, while [Colonoscopy](/treatments/cancer-screening/colonoscopy/) may help investigate bowel symptoms before surgery.

Your team will explain fasting, bowel preparation, medicines and whether you need to stop or adjust any medicine. Plan for help with meals, washing and transport after discharge. Early walking, breathing exercises and gradual eating may be part of recovery, according to your surgical instructions. Keep the incision clean and follow the stoma nurse’s advice if a stoma is present.

Ask when the pathology result is expected, what foods and activities are suitable, and how bowel changes should be recorded. Do not change medicines or wound care without checking with the surgical team.

Contact the surgical team urgently for increasing abdominal pain, a swollen or hard abdomen, repeated vomiting, fever, worsening wound redness, pus, heavy bleeding, chest pain, breathlessness, or a stoma that changes colour or stops working with new pain. Use the emergency service for severe or rapidly worsening symptoms.

Ask which bowel segment will be removed, whether the ends can be joined, when a stoma might be needed, how the incision will be managed, what pathology may show, and which treatments could follow. Ask who to call after discharge and what symptoms require urgent review.
