Manometry
The manometry is a diagnostic procedure used to examine the pressures at different levels or strength of contraction of various organs such as the esophagus, the final section of the intestine, urethra or pelvic floor. This test involves the introduction of a thin, thin tube with holes, which at its end can expect a deflated balloon is inflated once the probe positioned at the desired location by a motion sensitive receptors that are connected to a computer wherein the activity detected is recorded. In the case of esophageal manometry, the movements of the esophagus and esophageal sphincter register to check its operation if the patient has trouble swallowing or chest pain, which is the more frequent use of this test. Although, now also used to measure and detect possible complications arising from lack or excess pressure in the colon ( anorectal manometry ) or urethra (urinary manometry ).
