Central Mesocolic Excision (CME) for Colon Cancer

For colon cancer, simply removing the tumour is not enough. The surrounding tissue and lymph nodes must also be removed to lower the chance of recurrence. Central Mesocolic Excision (CME) is a modern technique that does exactly that.

What it involves

The surgeon removes the cancerous section of colon together with the “mesocolon” (the tissue that contains lymph nodes and blood vessels). Blood vessels are tied off close to their origin, ensuring complete clearance.

Why it matters

This thorough approach leads to higher lymph node removal, which improves staging accuracy and reduces the risk of cancer returning.

Benefits

Studies show better long-term survival compared with more limited resections.

What to expect

CME can often be done through keyhole (laparoscopic) or robotic surgery, meaning faster recovery, less pain, and shorter hospital stay.

Patient FAQ – CME

• Who is a candidate? Patients with colon cancer who are suitable for surgical removal of the tumour.
• What are the risks? Risks are similar to other bowel surgeries: leakage at the join (anastomosis), infection, bleeding, or bowel obstruction.
• How long is recovery? Most patients stay in hospital for 2–3 days and take 2–4 weeks for full recovery.
