Colostomy (or intestinal opening) refers to a particular surgical treatment for retrieving one end of the colon (large intestine) from the abdominal wall. Stools drain into the bag adjacent to the abdomen, called a stoma appliance. This is basically done after bowel resection, bowel blockage and injuries. Colostomy is basically performed when the patient is under general anesthesia, with a big surgical cut or several small cuts (laparoscopy) in the abdomen, depending upon the procedure to be executed. Generally, the cut is made at the center of the abdomen, and if required, the bowel repair is also done. Colostomy can be short term or permanent.
