Manometry evaluates the esophagus’ muscular contractions – their amplitude and wave action – and the pressure, location and relaxation of the LES. Surgeons need to know whether the motility of the esophagus is poor when considering a fundoplication.
Types of Manometry
- Anorectal manometry - measuring pressure in the anal canal and rectum for patients presenting with incontinence or constipation.
- Esophageal manometry - measuring pressure in the esophagus for patients presenting with chest pain or painful spasms of the esophagus.
- Antroduodenal manometry - measuring pressure in the stomach and small bowel, using radioactive markers, for patients presenting with nausea, abdominal bloating or pain.
