background: subjective assessment of primary achalasia is not accurate. we aimed to evaluate surface of barium retention in the objective assessment of these patients. materials and methods: subjective and objective esophageal functions of 99 patients with primary achalasia were evaluated initially and 43 of them were reevaluated one month after balloon dilation. results: predilation: â  9cases...

Chronic inflammatory demyelinating polyneuroradiculopathy (CIDP) is an immune mediated disorder characterized by progressive developing or relapsing symmetrical motor or sensory symptoms in more than one limb over a period of two months. Achalasia, as a primary esophageal motility disorder, is also characterized by increasing the tone of lower esophageal sphincter, absence or incomplete sphinct...

a correlation stud on the subjective criteria versus lower esophageal sphincter pressure in idiopathic achalasia

BACKGROUND Sleeve gastrectomy may alter esophageal motility and lower esophageal sphincter pressure. AIM To detect manometric changings in the esophagus and lower esophageal sphincter before and after sleeve gastrectomy in order to select patients who could develop postoperative esophageal motilitity disorders and lower esophageal sphincter pressure modifications. METHODS Seventy-three pati...

The purpose of this study was to determine the relation between posturally increased intra-abdominal pressure and lower/upper esophageal sphincter pressure changes in patients with gastroesophageal reflux disease. We used high resolution manometry to measure pressure changes in lower and upper esophageal sphincter during bilateral leg rise. We also examined whether the rate of lower and upper e...

Studies were performed in anesthetized opossums to determine the influence of binding of circulating gastrin with a high titer gastrin antiserum on lower esophageal sphincter pressure. Gastrin antiserum or control antiserum was administered intravenously in successive doses of 0.02, 0.1, and 0.5 ml/kg on separate days. The lower esophageal sphincter pressures were measured for 1 h before and fo...

HYPOTHESIS Anatomic changes induced by large hiatal hernia may alter esophageal pressure topography measurements made during high-resolution manometry. DESIGN Retrospective study. SETTING Single-institution tertiary hospital. PATIENTS Ninety patients with large (>5 cm) hiatal hernias on endoscopy were compared with a control group of 46 patients without hernia selected from the same datab...

BACKGROUND Bariatric operations may alter esophageal motility; however, there is a paucity of studies of the esophageal motility with high resolution manometry. AIM To study patients after Roux-en-Y gastric bypass for morbid obesity with high resolution motility. METHODS Were included 18 asymptomatic patients (17 women, mean age 53 years) after undergoing to Roux-en-Y gastric bypass for mor...

The interaction of gastrin and secretin, in the regulation of human lower esophageal sphincter competence, was studied in 54 normal subjects. A dose-response curve, for the lower esophageal sphincter, was constructed from the rapid intravenous injections of synthetic gastrin I (amino acid sequence 2-17). This curve was sigmoid shaped and showed a peak response that was 460.0 +/-24.0% (mean +/-2...
