Upper Esophageal Sphincter Resting Pressure Varies during Esophageal Manometry
BACKGROUND The upper esophageal sphincter is composed of striated muscle. The stress of intubation and the need to inhibit dry swallows during an esophageal manometry test may lead to variations in basal pressure of this sphincter. Upper esophageal sphincter is usually only studied at the final part of the test. Was observed during the performance of high resolution manometry that sphincter pre...
متن کاملSleeve sensor versus high-resolution manometry for the detection of transient lower esophageal sphincter relaxations.
Transient lower esophageal sphincter relaxations (TLESRs) are the most important mechanism by which gastroesophageal reflux occurs, and sleeve sensor manometry is the gold standard for detection of TLESRs. The aim of this study was to evaluate manometry with closely spaced sideholes (high-resolution manometry) for the detection of TLESRs as an alternative. In 12 patients with gastroesophageal r...
متن کاملHigh Resolution Manometry and pH step-up method on the localisation of the lower esophageal sphincter.
Ambulatory pH-recording is one of the key diagnostic studies in gastroesophageal reflux disease. It is recommended that the pH-probe is inserted 5 cm above the proximal border of the lower esophageal sphincter (LES) and the latter should be determined optimally with manometry [1]. However, some studies have shown that the pH step-up especially done in the supine position could be almost as accu...
متن کاملHow to Perform and Interpret Upper Esophageal Sphincter Manometry
Manometry of the pharynx and the upper esophageal sphincter (UES) provides important information on the swallowing mechanism, especially about details on the pharyngeal contraction and relaxation of the UES. However, UES manometry is challenging because of the radial asymmetry of the sphincter, and upward movement of the UES during swallowing. In addition, the rapidity of contraction of the pha...
متن کاملHigh-Resolution Manometry Reveals Normal Esophageal Motility, Including Lower Esophageal Sphincter Function, After Vagus Nerve-Preserving Gastrectomy
Objective: We developed two new methods to preserve lower esophageal sphincter (LES) function and the vagus nerve in performing total gastrectomy (TG) and partial cardiectomy (PC) for patients with early-stage gastric cancer. We used two methods compared to standard TG and evaluated outcomes using high-resolution manometry (HRM) to analyze esophageal function. Methods: We used HRM to evaluate 3...
