Esophageal Manometry is a diagnostic procedure that measures the pressure and movement of the esophagus and its sphincters. A thin, pressure-sensitive tube is passed through the nose, down the esophagus, and into the stomach. The patient swallows water, and the tube measures the muscle contractions and relaxation of the esophagus and its sphincters. This test is used to diagnose conditions such as achalasia, esophageal spasms, and gastroesophageal reflux disease (GERD).

Anorectal Manometry is a diagnostic procedure that measures the pressure and function of the muscles in the rectum and anus. A thin, flexible tube with a balloon at the end is inserted into the rectum. The tube measures muscle contractions, relaxation, and the coordination of the anal sphincter and pelvic floor muscles during activities like squeezing and bearing down. This test helps diagnose conditions such as chronic constipation, fecal incontinence, and Hirschsprung's disease.
