Manometry

Manometry is a diagnostic procedure that measures the pressure within various parts of the body's gastrointestinal tract. This technique is commonly used in the evaluation of conditions affecting the esophagus, stomach, and rectum.

Overview

Manometry involves the use of a thin, flexible tube (manometer) that is passed through a body opening or a small incision. The manometer is equipped with pressure sensors that can detect and measure the pressure exerted by the muscles and sphincters of the gastrointestinal tract. The data collected by the manometer is then interpreted by a medical professional to diagnose various conditions.

Procedure

The procedure for manometry varies depending on the part of the body being examined. For esophageal manometry, the manometer is passed through the nose, down the esophagus, and into the stomach. For rectal manometry, the manometer is inserted through the anus and into the rectum. The patient may be asked to perform certain actions, such as swallowing or squeezing, to test the function of the muscles and sphincters.

Uses

Manometry is used to diagnose a variety of conditions, including:

• Achalasia: A condition characterized by difficulty swallowing due to a lack of normal muscle contractions in the esophagus.
• Gastroesophageal reflux disease (GERD): A condition in which stomach acid frequently flows back into the esophagus, causing irritation.
• Hirschsprung's disease: A condition that affects the large intestine and causes problems with passing stool.

Risks

While manometry is generally considered safe, there are some risks associated with the procedure. These may include discomfort or pain, nosebleeds, and, in rare cases, perforation of the gastrointestinal tract.
