Colo-rectal surgery is performed at the most of cases by laparoscopy or robotic surgery and involves a resection of a segment of colon or rectum with subsequent anastomosis. This anastomosis can be protected by a temporary ileostomy in case of low rectal resection, of recently protected by a stent.
In case of malign pathology, a correct lymphadenectomy is very important, to optimize the postoperative chemotherapy result and the survival. The lymphadenectomy is a criteria of quality of the oncological surgery.
In case of benign pathology, the resection is limited to the affected segment, like in case of diverticular disease, where the segment of the resected colon is limited to the distribution of the diverticulum. In case of Crohn disease with stenosis on the last portion of the ileal loop, the ileo-colic resection is minimal in term of length, to preserve the maximum of the digestive tube in case of disease progression and later reoperation. For benign pathology, the lymphadenectomy is not essential.
