The upper esophageal sphincter (ues) is a high-pressure zone that separates the pharyngeal lumen and the esophageal lumen. It consists of the proximal cervical esophagus, cricopharyngeus, and … Patients with achalasia were significantly more likely to have ues abnormalities as compared with normal ues function (57. 2% vs.

In this retrospective study involving 498 consecutive patients who underwent high-resolution esophageal manometry, we found that impaired relaxation alone was the most common upper … Functional obstruction at the level of the upper esophageal sphincter due to failure of relaxation of the cricopharyngeal muscles; Often associated with a pharyngoesophageal diverticulum The upper esophageal sphincter elevates when swallowing and these more concentrated sensors can capture a generalized pressure in the area. This technique is used to measure pressures in a normal … The introduction of high resolution esophageal manometry (hrm) has allowed the ability to assess the upper esophageal sphincter (ues). However, ues abnormalities are often interpreted as …

However, ues abnormalities are often interpreted as … Although the clinical significance of a hypertensive ues is variable, it has been suggested that it may be a result of esophageal acid exposure in patients with gastroesophageal reflux disease (gerd).
