by laparotomy or open way
The colectomy by open way is sometimes called “hemicolectomy” or “segmentary colectomy by laparotomy”
It is the surgical operation most employed for the treatment of cancers of the colon. This intervention consists in removing the portion reached of the colon just as the lymphatic ganglia neighbouring years the framework of an open surgery.
The intervention is done by an opening (incision) practised in the abdomen, and one carries out the ablation of the part reached of the colon as well as small portion of the healthy colon on both sides of that Ci.
Usually, approximately the quarter or one the third of the colon is removed, but all depends on the size and the site of the tumour.
The ends of the healthy parts are then braided (bent together)
It is important to withdraw more a large number of lymphatic ganglia to determine the stage of cancer and the operational post treatment which is appropriate.
