Manometry is a diagnostic technique used to measure pressure within the gastrointestinal tract. It involves the insertion of a thin, flexible tube with pressure sensors along its length into the gastrointestinal tract, typically through the nose or mouth. The tube is then advanced through the esophagus, stomach, and small intestine, and pressure measurements are taken at various points along the way. Manometry can be used to evaluate the function of the esophagus, stomach, and small intestine, and can help diagnose conditions such as achalasia, gastroesophageal reflux disease (GERD), and gastroparesis. Manometry can also be used to evaluate the efficacy of treatments for these conditions, such as medications or surgical interventions. There is only very little use in the field of critical care medicine.
