Anal manometry, (a small catheter placed into the anus to record pressure as patients relax and tighten the anal muscles) can demonstrate muscle strength.
Nerve function test for nerves supplying anal muscles
What can be done to correct the bowel incontinence?
Avoid Constipating medications
Muscle strengthening exercises
Biofeedback to help patient sense when stool is ready to be evacuated and help strengthen the muscles.
Surgical muscle repair
When there is nerve damage or anal muscles are damaged beyond repair, an artificial sphincter may be implanted. The artificial sphincter is a plastic, fluid filled doughnut that is surgically implanted around the damaged anal sphincter. This artificial sphincter keeps the anal canal closed. When an individual wants to have a bowel movement, the fluid can be pumped out of the doughnut to allow the anal canal to open.
