| Ileostomy Stoma surgery could be required when all or part of colon (large intestine) is removed as a result of inflammatory bowel diseases such as ulcerative colitis or Crohn's disease. Stoma is a bud like artificial structure created when the opening of the bowel is stitched to the skin of the abdomen. A pouch can then be connected to the stoma to have the waste collected. When the surgical procedure involves the large intestine (colon), the stoma surgery is called colostomy; when the small intestine is involved (ileum), it is called ileostomy. |
