Manometry using gas-perfused catheters is a suitable alternative. There have been only a few publications about this.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec id=\"j_med-2018-0036_s_007_w2aab3b7d432b1b6b1aab1c16b2Aa\">\n                  <jats:title>Objectives and methods<\/jats:title>\n                  <jats:p>The results for esophageal manometry in 1700 patients were retrospectively analyzed based on the clinical reports and the manometry data.

The indications for esophageal manometry were GER symptoms in 58.5% (pathological DeMeester score in 41.8%), dysphagia in 12.4%, and already known achalasia in 8.9%. Motility disorders could be found in 40% of the patients with GER symptoms (51% of the patients with pathological DeMeester score), and in 88% of achalasia patients. The resting LES pressure was 8.9\u00b15.94 mmHg with GER symptoms, 16.4\u00b112.79 mmHg without GER symptoms, and 26.8\u00b114.03 mmHg with achalasia.

The suitability of gas perfusion with helium for esophageal manometry depends on physical and technical requirements, such as a constant gas flow, a dead space in the transducer, and the catheter being as small as possible. In consideration of this, the detection of the pressure changing in swallowing acts is excellent. The measured LES pressures are generally lower than with other methods like with water-perfused or solid-state catheters, possibly because of the higher compliance in a gas-filled surrounding. The normal values in gas-perfusion manometry are comparable but not identical with the values of other manometric methods.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1515\/med-2018-0036","type":"journal-article","created":{"date-parts":[[2018,6,15]],"date-time":"2018-06-15T22:16:32Z","timestamp":1529100992000},"page":"232-236","source":"Crossref","is-referenced-by-count":0,"title":["The esophageal manometry with gas-perfused catheters"],"prefix":"10.1515","volume":"13","author":[{"given":"Sven","family":"H\u00f6hne","sequence":"first","affiliation":[{"name":"Martin-Luther-University Halle-Wittenberg, University Hospital , Clinic of Pediatric Surgery , 06120 , Halle , Ernst-Grube Street 40 , Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin","family":"Arndt","sequence":"additional","affiliation":[{"name":"Martin-Luther-University Halle-Wittenberg , Department of Operative and Conservative Medicine in Children and Adolescents , Clinic of Pediatric Surgery, Laboratory of Function Diagnostic , Halle , Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Viola","family":"Hesse","sequence":"additional","affiliation":[{"name":"Martin-Luther-University Halle-Wittenberg , Department of Operative and Conservative Medicine in Children and Adolescents , Clinic of Pediatric Surgery, Laboratory of Function Diagnostic , Halle , Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","published-online":{"date-parts":[[2018,6,14]]},"reference":[{"key":"2022042708342984470_j_med-2018-0036_ref_001_w2aab3b7d432b1b6b1ab2b1b1Aa","doi-asserted-by":"crossref","unstructured":"Bredenoord AJ, Fox M, Kahrilas PJ, Pandolfino JE, Schwizer W, Smout AJ; International High Resolution Manometry Working Group: Chicago classification criteria of esophageal motility disorders defined in high resolution esophageal pressure topography.
