A colostomy is an opening where the large intestine is attached to the abdominal wall. A replaceable bag that encloses the colostomy is worn by the patient to collect stool.
Possible risks and side effects of surgery depend on several factors, including the extent of the operation and a person’s general health before surgery. Problems during or shortly after the operation can include bleeding from the surgery, infections at the surgery site, and blood clots in the legs. There is a minor but real risk of leakage from the bowel stitch line. Also there are chances of urinary retention. There may be ‘adhesion’ formation & distension of the belly.
When you wake up after surgery, you will have some pain and will need pain medicines for a few days. For the first couple of days, you may not be able to eat or you may be allowed limited liquids, as the rectum needs some time to recover. Most people are able to eat solid food again in a few days.
