(Greek: anus, rectum)
Large bowel resection is surgery to remove part of your large bowel. The large bowel connects the small intestine to the anus. It is also called the large intestine or colon.
In most cases, the bowel is cleaned before the surgery with enemas and medication.
The surgery is performed while the patient is under general anesthesia. A cut is made in the abdomen. The diseased part of the large bowel is removed and the two healthy ends of the bowel are sewn back together (resected). Then the cut is closed.
If the entire colon and rectum is removed, it is called a proctocolectomy.
A bowel resection may be performed as a traditional "open" procedure or as a minimally invasive laparoscopic procedure.
To aid in the healing of the bowel, a temporary opening of the colon through the abdominal wall may be created. This is called a colostomy. The end of the bowel near the small intestine is then passed through the abdominal wall, and stitched in place. A drainage bag (stoma appliance) is placed around the opening.
In most cases, the colostomy is temporary and can be closed with another operation at a later date. If a large portion of the bowel is removed, the colostomy may be permanent.
The large bowel absorbs a significant amount of water from digested food. When the colon is bypassed by a colostomy, loose or liquid stool (feces) will collect in the drainage bag. Careful skin care and a well-fitting colostomy bag are necessary to reduce skin irritation around the colostomy.
2. The surgical removal of the entire colon and rectum and the creation of an end ileostomy.
An ileostomy is an operation that makes it possible for feces (human wastes) to leave the body, after the colon and rectum are removed, in which an opening is made in the abdomen and the bottom of the small intestine (ileum) attaches to it.
Another explanation of an ileostomy states that it is an opening into the ileum, the lower part of the small intestine, from the outside of the body; therefor, an ileostomy provides a new path for waste material to leave the body after the colon and the rectum have been removed.
