Manometry is the study where a pressure sensing thin probe is passed from the nose or anus to study the pressure of esophagus, lower esophageal sphincter, rectum and anal canal.
Esophageal manometry
Esophgeal manometry is performed by nasal route, to study the pressure in esophagus and lower esophageal sphincter
Indication of esophageal manometry are :
- Dysphagia – in pateints with normal UGI endoscopy, motor disorders are common cause in this setting, which can be diagnosed by manometry.
- Gastroesophageal reflux- Low esophgaeal sphincter pressure predisposes to acid reflux symtopms.
Anorectal manometry
Anorectal manometry is done by the anal route.
Indications of anorectalmanometry are:
- Anal incontinence
- Chronic constipation because of neuronal diseases
24 hour pH study
24 hour pH study is indicated in patients with suspected gatroesophageal reflux disease. 24 hour pH study is an ambulatory study, where pH probe is passes through the nose to lower esophagus, probe has to be kept in situ for 24 hours. All the reflux episodes from stomach to esophagus leads to change in esophageal pH, which are sensed by pH probe, and are recorded in data recorder, which is later studied.
