What surgical operations are done to treat bowel incontinence?

Depends on cause: For example, incontinence caused by inflammatory bowel disease is often treated medically, with surgery (removal of part or all of the colon) as a last resort. Celiac disease, caused by a gluten allergy, can often be treated by changing diet. Incontinence caused by an anatomic problem such as a disrupted anal sphincter can be treated with physical therapy or surgery.

Several options: In the past, we overlapped the anal sphincter muscle. This had high complication rate and wasn't very effective. Now we have secca, which is an outpatient procedure which stiffens the sphincter muscle. We also have interstim, which is a very effective, low risk outpatient treatment where a nerve stimulator is inserted into the nerve that controls continence. See a colorectal surgeon.
