A polyp is a projection (growth) of tissue from the inner lining of the colon into the lumen (hollow center) of the colon. Different types of polyps look different under the microscope. Polyps are benign (non-cancerous) growths, but cancer can start in some types of polyps.
Colectomy can be used to treat a variety of diseases, including removal of colon or rectal cancer or large polyps (growths that arise on the lining of the colon), diverticular disease, inflammatory bowel disease (Crohn’s disease or ulcerative colitis), or bleeding that cannot be stopped.
members affected by hyperplastic polyposis (multiple hyperplastic polyps), the polyps may lead to colon cancer. Other types of polyps include adenomatous polyps, from which 95% of colon cancers arise. These polyps are larger than hyperplastic polyps. Hamartomatous polyps and inflammatory polyps are two other types of benign colon polyps.
The most common location for Crohn's disease to manifest is the last, or terminal portion, of the small intestine, also known as the ileum. If Crohn's disease patients received surgery for an ileo-anal pouch, the surgeons would eventually have to undo their work and create an ileostomy.
Lateral internal sphincterotomy is an operation performed on the internal anal sphincter muscle for the treatment of chronic anal fissure. The internal anal sphincter is one of two muscles that comprise the anal sphincter which controls the passage of feces.
Rectopexy is a surgical procedure used to correct rectal prolapse, a condition characterized by a weakening of the muscles that hold the rectum in place. Though the exact cause of this problem is unknown, there are several conditions that may contribute to its development.
