Human upper esophageal sphincter pressure profile
American Journal of Physiology-Gastrointestinal and Liver Physiology, 1980The pressure profile of the upper esophageal sphincter was characterized in nine normal subjects. Directionally oriented intraluminal pressures were recorded, at 0.5-cm intervals over a 6-cm segment that encompassed the sphincter, by a high-fidelity low-compliance recording system.

Controlled twitch mouth pressure reliably predicts twitch esophageal pressure
Respiratory Physiology & Neurobiology, 2007The present study hypothesized that twitch mouth pressure (TwPmo) can reliably predict intrathoracic pressure swings reflected by twitch esophageal pressure (TwPes) using a controlled and automated trigger technique. TwPmo, TwPes, and transdiaphragmatic pressure (TwPdi) following bilateral anterior magnetic phrenic nerve stimulation were measured in 21

[Esophageal pressure and transpulmonary pressure monitoring].
Zhonghua wei zhong bing ji jiu yi xue, 2018Esophageal pressure monitoring provides a minimally invasive method to assess the pleural pressure, which can be used to differentiate the lung and chest wall mechanics. The information of transpulmonary pressure, work of breathing, intrinsic positive end-expiratory pressure and respiratory muscle performance can facilitate the proper setting of ...

Clinical significance of esophageal variceal pressure in patients with esophageal varices
Journal of Hepatology, 1994In 40 patients with esophageal varices, esophageal variceal pressure was assessed endoscopically using a pneumatic pressure sensor. The effects of vasopressin or nitroglycerin on variceal pressure and endoscopic findings were also assessed in two groups of seven patients.

Correlation of lower esophageal mucosal ring and lower esophageal sphincter pressure
Digestive Diseases and Sciences, 1994We assessed the relationship of lower esophageal sphincter pressure (LESP) to presence and absence of lower esophageal mucosal ring (LEMR) in 66 patients to determine if the LEMR was more likely related to prolonged sphincter hypotension. This potential relationship is of interest because LEMR may be due to reflux esophagitis.

Lower esophageal sphincter pressure in Chagas' disease
Digestive Diseases and Sciences, 1990It is known that lower esophageal sphincter (LES) pressure in patients with idiopathic achalasia is higher than in normal subjects, but in patients with Chagas' disease, who have esophageal disease with similar clinical, manometric, and radiologic results, studies of LES pressure show contradictory findings. We measured the LES pressure in 118 patients

Abnormal esophageal pressures in reflux esophagitis: cause or effect?
The American journal of gastroenterology, 1986Thirteen patients with gastroesophageal reflux disease underwent esophageal manometric evaluation during acute exacerbations and disease remission to evaluate lower esophageal sphincter and peristaltic pressure in response to treatment. No change was noted in lower esophageal sphincter pressure (15.2 +/- 2.6 mg versus 14.3 +/- 1.8 mm Hg) or peristaltic

Manometric features of eosinophilic esophagitis in esophageal pressure topography.
Neurogastroenterology and motility, 2011Although most of the patients with eosinophilic esophagitis (EoE) have mucosal and structural changes that could potentially explain their symptoms, it is unclear whether EoE is associated with abnormal esophageal motor function. The aims of this study were to evaluate the esophageal pressure topography (EPT) findings in EoE and to compare them with ...
