Anorectal manometry is done to evaluate patients with constipation and/or fecal incontinence. It helps identify the specific problems and the best treatments. The most common problems studied are:

• Fecal Incontinence (inability to control evacuation of the bowel)
• Anorectal cause of constipation
• Need for surgery or biofeedback
• Hirschsprung's disease in children (an inborn absence of nerves in the wall of the colon)

• Do not eat or drink anything after midnight (If you are diabetic, please talk to your primary care doctor)
• Give yourself a Fleet enema 2 hours prior to your study (You can get the Fleet enema from a pharmacy or supermarket)
• You may take scheduled medications at least 2 hours prior to the study with small sips of water
