High-Resolution Anorectal Manometry

High-resolution 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)

To prepare for the study:

  • 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
