LES Manometry
|
The Lower Esophageal Sphincter (LES) consists of smooth muscles which are normally contracted to maintain closure. On swallow, the LES opens and relaxes. To investigate the LES, a pressure catheter is pulled from the stomach through the LES into the esophagus. The LES investigation is primarily intended to perform the Rapid Pull Through technique, where the catheter is pulled out of the stomach into the esophagus at a constant speed by means of a puller device. In case 4 or more channel are measured radially, the obtained data can be used to create a three dimensional image of the LES. |
