A colostomy is a medical procedure performed to divert one end of the colon (part of the bowel) through an opening in the stomach. Colostomy is performed to treat bowel cancer, Crohn’s disease, Diverticulitis, anal cancer, vaginal cancer or cervical cancer, bowel incontinence, and Hirschsprung’s disease. A stoma or surgical opening is created in the abdomen, and the upper part of the colon is attached to the stoma. Colostomy closure refers to the surgery in which the colostomy is closed, usually about 2 to 3 months after the main repair of the defect/disease. In this procedure, the hole in the abdomen is closed and the two sections of the colon are reconnected.
