DefinitionColostomy is a surgical procedure that brings one end of the large intestine out through the abdominal wall. Stools moving through the intestine drain into a bag attached to the abdomen.Alternative NamesIntestinal openingDescriptionThe procedure is usually done after bowel resections, bowel obstruction, or injuries. The colostomy may be temporary or permanent.Colostomy is done while you are under general anesthesia (unconscious and pain-free). It may either be done with a large surgical cut in the abdomen, or with the use of a small camera and several small cuts (laparoscopy).The type of approach used depends on what other procedure needs to be performed. In general, the surgical cut is made in the abdomen. The bowel resection or repair is performed as needed.See also:Intestinal
