Laparoscopy/Keyhole surgery vs Open surgery

Colectomy by open surgery

CLASSIC COLECTOMY

by laparotomy or open surgery.

The colectomy by open surgery is also called a  « hemicolectomy » or « segmental colectomy by laparotomy ».

It is the most frequently employed surgical operation for treating colon cancer. This open surgery operation involves removing the portion of the colon which is affected, as well as the adjacent lymphatic ganglions.

The surgery involves making an incision in the abdomen, and removing the affected part of the  colon along with some small surrounding parts of the healthy colon.

Normally, a quarter or a third of the colon is removed, but this depends on the size and location of the tumour.

The ends of the healthy parts are then sewn together.

It is important to remove as many lymphatic ganglions as possible in order to determine the stage of the cancer and the post-operative treatment required.

Colectomy by laparoscopy/keyhole surgery

MINI INVASIVE COLECTOMY

COELIOSCOPY or LAPAROSCOPY

A Colectomy carried out using a video endoscope introduced by coelioscopy, and subsequently a laparoscopy.

This minimally invasive technique is recommended for early stage cancers.

It involves removing the portion of the colon which is affected, as well as the adjacent lymphatic ganglions, by making several small incisions in the abdomen wall through which the necessary instruments and surgical tools are introduced, rather than making one long incision. 

One of the instruments is a  fiber-optic endoscope which has a light and tiny camera at the end enabling the images to be viewed on a video monitor.

Once the affected part of the colon has been resected, one of the small incisions is enlarged in order to remove it.

As the incisions made are much smaller than for an open surgery colectomy,  the patient recovers more quickly and endures less pain than after a classic operation for removing the colon by open surgery.

A colectomy by laparoscopy/keyhole surgery is just as successful at treating an affected colon as by open surgery, but must be undertaken by a surgeon specialising in the technique.
