Upper esophageal sphincter during transient lower esophageal sphincter relaxation: effects of reflux content and posture.
Although some studies show that the upper esophageal sphincter (UES) contracts during transient lower esophageal sphincter relaxation (TLESR), others show that it relaxes. We hypothesized that the posture of the subject and constituents of gastroesophageal reflux (GER) may determine the type of UES response during the TLESR. High-resolution manometry and esophageal pH/impedance recording were p...
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 کامل[Transient lower esophageal sphincter relaxation and the related esophageal motor activities].
Transient lower esophageal sphincter (LES) relaxation (TLESR) is defined as LES relaxation without a swallow. TLESRs are observed in both of the normal individuals and the patients with gastroesophageal reflux disorder (GERD). However, TLESR is widely considered as the major mechanism of the GERD. The new equipments such as high resolution manometry and impedance pH study is helped to understan...
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...
