Colorectal cancer surgery: planning and recovery

The exact operation depends on whether the tumour is in the colon or rectum, how close it is to the anal muscles, whether it involves nearby organs, and whether cancer has spread. Surgery may use keyhole, robotic, or open access according to anatomy and clinical need.

After the affected bowel segment is removed, the surgeon may join the healthy ends. A stoma brings bowel through an opening in the abdomen so waste enters a bag. It may protect a healing join or be necessary when a safe reconnection is not possible; it can be temporary or long term depending on the operation.

If colorectal cancer has reached the liver, a specialist team may consider liver-directed surgery in selected circumstances. Drug treatment or radiotherapy can also be placed before or after an operation, especially for rectal cancer or disease beyond the bowel.

Give the surgical team a complete medicine list and disclose blood thinners, diabetes treatment, allergies, smoking, sleep apnoea, and previous abdominal operations. Follow instructions on eating, drinking, bowel preparation, and medicine timing. A stoma nurse can mark a comfortable site and teach bag care if a stoma is possible.

Plan practical help for the first part of recovery. Walking, breathing exercises, pain control, nutrition, and gradual return of bowel activity support recovery. Follow lifting and wound-care limits, and record changes in stool or stoma output.

Contact the surgical team urgently for fever, worsening abdominal pain, repeated vomiting, increasing abdominal swelling, inability to pass stool or wind, a wound that becomes red or drains pus, heavy rectal bleeding, or a sudden major change in stoma output. Chest pain, severe breathlessness, fainting, or a painful swollen calf requires emergency assessment.

After discharge, some tiredness and changing bowel frequency can occur, but symptoms that intensify rather than settle should be reported. The team should provide a direct contact route and instructions specific to the operation.

Ask which bowel segment will be removed, whether nearby organs may be involved, and what would make a stoma necessary. Discuss the planned surgical approach, pain relief, expected bowel changes, pathology review, recovery restrictions, and the possibility of additional cancer treatment. If a temporary stoma is proposed, ask what must happen before reversal can be considered.
