Understanding Surgical Procedures : Hemicolectomy

Colectomy procedure to remove one side of the colon is hemicolectomy

Understanding Surgical Procedures : Hemicolectomy – Hemicolectomy involves surgical removal of a partof the colon (large intestine). Depending on the part of the colon that is removed, the operation is named as right hemicolectomy (removal terminal 10 cm of small intestine, caecum, ascending colon and part of transverse colon), left hemicolectomy (removal of part of transverse colon, descending colon), sigmoid colectomy and transverse colectomy.

This operation is performed for a number of conditions such as colon cancer and non-cancerous conditions i.e. Crohn’s disease

complicated diverticular disease.

The modern surgery for colon cancer involves “central (at the origin) ligation” of arteries supplying the colonic segment to completely remove the draining lymph nodes as part of surgical specimen.

Hemicolectomy can be performed by open, laparoscopic or robotic techniques.

Our technique of central vascular ligation (CVL) and dissecting the plane for complete mesocolic excision (CME)

Hemicolectomy Surgical Procedures

Hemicolectomy is generally considered a safe surgical procedure. However, like any surgical procedure, it does carry some risks, including anastomotic leaks, wound infection and bleeding. At Max Super speciality Hospital, Saket, New Delhi we have analyzed our outcomes of colorectal surgery. We have evaluated surgical outcomes on validated international quality benchmarks / scoring systems – American College of Surgeons NSQIP risk calculator and Colo Rectal POSSUM score (England). Our outcomes are comparable to best of International standards. We are happy to share that cost of colorectal surgery at our center is only a fraction of that incurred at well-endowed western medical centers. Our results have been well received at national (Annual Conference of Indian Association of Surgical Gastroenterology, AIIMS, New Delhi 2019) international (Society of American Gastrointestinal & Endoscopic Surgeons Annual Conference 2019 at Baltimore, USA – and further we have published our results in prestigious Journal of Minimal Access Surgery.


We were invited to present our technique of laparoscopic right hemicolectomy for ileo-colic Crohn’s disease at World Congress of International Society of Surgery at Vienna, Austria 2022.
