High-resolution esophageal manometry.High-resolution esophageal manometry is a novel tool in the diagnostic armamentarium ar·ma·men·tar·i·um n. pl. ar·ma·men·tar·i·ums or ar·ma·men·tar·i·a The complete equipment of a physician or medical institution, including drugs, books, supplies, and instruments. for dysphagia. Esophageal manometry is the standard method of diagnosing achalasia Achalasia Definition Achalasia is a disorder of the esophagus that prevents normal swallowing. Description Achalasia affects the esophagus, the tube that carries swallowed food from the back of the throat down into the stomach. and other esophageal motility disorders. (1) Manometry manometry /ma·nom·e·try/ (-e-tre) the measurement of pressure by means of a manometer. anal manometry is also the most accurate method of identifying the lower esophageal sphincter lower esophageal sphincter n. A ring of smooth muscle fibers at the junction of the esophagus and stomach. Also called cardiac sphincter. for pH catheter placement, ensuring valid 24-hour monitoring data. For demonstration purposes, we performed high-resolution manometry on a normal patient with the ManoScan 360 36-channel catheter system (Sierra Scientific Instruments; Los Angeles). This catheter is equipped with 36 circumferential sensors that can simultaneously record pressure along the entire esophagus in most patients. The results are shown in real time as a spatiotemporal graph and pressure profiles for quantitative wave amplitudes (figure, A and B). This catheter has the potential to not only enhance our ability to diagnose and manage pharyngeal and esophageal dysmotility, it may also make possible biofeedback treatment to facilitate a safer swallow. The procedure is well tolerated. [FIGURES A-B OMITTED] Reference (1).Murray JA, Clouse RE, Conklin JL. Components of the standard oesophageal manometry. Neurogastroenterol Motil 2003;15:591-606.
