One well-known form of an artificial stoma is a colostomy, which is a surgically created opening in the large intestine that allows the removal of feces out of the body, bypassing the rectum, to drain into a pouch or other collection device. The historical practice of trepanation was also a type of stoma.he point of exiting is what is known as the stoma. For greatest success and to minimize negative effects, it is preferable to perform this procedure as low down in the tract as possible, as this allows the maximal amount of natural digestion to occur before eliminating fecal matter from the body.
A colostomy is a surgical procedure to divert one end of the large intestine (colon) through an opening in the abdominal wall (tummy). The end of the bowel is called a stoma. A pouch is placed over the stoma to collect waste products that usually pass through the colon and out of the body through the rectum and anus (back passage). A colostomy can be permanent or temporary.
