Complete Mesocolic Excision with Central Vascular Ligation for Colon Cancer
September 5, 2026
Treating colon cancer, such as a tumour of the caecum or ascending colon, is no longer just a standard right hemicolectomy.
What the Technique Involves
Complete mesocolic excision with central vascular ligation ligates the feeding blood vessels of the tumour right at their origin, so that every draining lymph node is removed along with the complete mesocolic fascia. The dissection extends beyond the fascia itself to ensure nothing is left behind.
The Evidence Behind It
This technique has been published in international journals and is associated with better overall survival compared with the standard approach. It can be performed laparoscopically, with the feeding vessels ligated at their origin and the retroperitoneal fascia taken along with the specimen.

This guide is based on a live Jivo Masterclass: Dr. Kaushal Kishore Yadav taught doctors across Africa on June 15, 2025.
FROM THE LIVE Q&A
Dr. Yagaram
Followed up: in a setup where frozen section pathology is not available, how can a surgeon be confident of a clear margin, and how should the patient be followed afterward?
Dr. Kaushal Kishore Yadav
Follow the natural avascular surgical plane, doing sharp dissection between the internal and external sphincter. On gross examination, aim for about one centimetre of margin at the lowest extent of the tumour, or three to five centimetres higher up depending on where the tumour is located. Stay within the correct surgical plane and the margin should come back clear; the final histopathology report, once it arrives, confirms this.

Frequently Asked Questions
Working in a region with very limited healthcare infrastructure, asked what to do when none of the described tests (MRI, CT, PET-CT, tumour markers) are available locally.▼
Do whatever is genuinely achievable under your own control. If something cannot be done locally, it is better to refer the patient to a centre where it can be done with precision, because cancer gives only one real chance to get the treatment pathway right.
Asked Dr. Yadav to clarify the name of the surgical technique he had just described for colon cancer.▼
It is called complete mesocolic excision with central vascular ligation, sometimes shortened to CME with CVL. The feeding blood vessels of the tumour are ligated right at their origin so that all the draining lymph nodes and the complete mesocolic fascia are removed together; this has been published in international journals and is associated with better survival than the standard technique.
Relayed a case: a patient with sigmoid colon cancer who has liver metastases only. How should a case like this be managed?▼
If the liver metastases are limited, roughly one to three, and can be completely removed, liver metastasectomy can be done at the time of the primary surgery or as a second stage. If the liver is diffusely involved in both lobes, there is no role for curative surgery and only palliative chemotherapy is appropriate. If instead there is peritoneal-only spread with no other site involved, cytoreductive surgery combined with HIPEC gives a survival advantage of about fifty percent in colorectal cancer, provided the disease is limited and combined with chemotherapy before and after.
Explained what an online OPD is, for doctors wanting to bring a relevant patient to Dr. Yadav.▼
When a Jivo doctor partner has a relevant patient, they collect the case details and share the information with the Jivo team in advance. The patient is invited to the partner doctor's own clinic, where Dr. Yadav then joins the consultation by video call, so the consultation is guided jointly by doctors in both India and Africa.
Relayed a French-speaking participant's request: will the session recording and presentation be shared afterward?▼
Yes. The webinar recording link will be shared with participants, and Dr. Yadav's presentation, in English, will also be shared.
What is complete mesocolic excision with central vascular ligation?▼
A technique for colon cancer that ligates the tumour's feeding blood vessels at their origin and removes the complete mesocolic fascia along with all draining lymph nodes.
Does this technique improve survival compared to standard colon cancer surgery?▼
Yes, it has been published in international journals and is associated with better overall survival than the standard technique.
Can complete mesocolic excision be done laparoscopically?▼
Yes, the feeding vessels can be ligated at their origin and the retroperitoneal fascia taken along with the specimen using a laparoscopic approach.
