6-Hour Antroduodenal Manometry

The purpose of a 6-hour antroduodenal manometry is to measure pressures in the stomach and small intestines before and after you eat. The measurements provide specific information on how your stomach and small intestines are working. The most common problems studied are:

  • Dyspepsia (painful digestion)
  • Chronic intestinal pseudo-obstruction, in which the symptoms and signs of an intestinal obstruction are present, yet there is no evidence of mechanical blockage
  • Gastroparesis (stomach paralysis)
  • Prediction of drug effect
  • Small intestinal bacterial overgrowth
  • Systemic diseases affecting GI motility (e.g., diabetes mellitus and progressive systemic sclerosis)
