Stepwise inflation of a luminal balloon, in which the CSA and pressure were measured by means of impedance planimetry and perfused low-compliance manometry, provided the distension stimulus. The parameters of elasticity were computed from steady state values of these measurements. The steady state pressure-CSA and pressure-radius relations were nonlinear. At the lowest and highest luminal pressure load of 1 and 10 kPa, the steady state CSAs were 39 \u00b1 3 and 91 \u00b1 4 mm2, respectively. The circumferential tension-strain distribution was nonlinear and showed an exponential behaviour that fitted well to the function tension = a\u00b7eb\u00b7stram. Differentiation of the function yielded the wall stiffness which also showed an exponential behaviour.<\/jats:p>","DOI":"10.1159\/000201333","type":"journal-article","created":{"date-parts":[[2009,2,7]],"date-time":"2009-02-07T01:50:30Z","timestamp":1233971430000},"page":"174-179","source":"Crossref","is-referenced-by-count":8,"title":["Pressure-Cross-Sectional Area Relations and Elasticity in the Rabbit Oesophagus in vivo"],"prefix":"10.1159","author":[{"given":"H.","family":"Gregersen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L.L.","family":"Christensen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,2,5]]},"container-title":["Digestion"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/201333","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000201333","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T08:42:24Z","timestamp":1777538544000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000201333"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,2,5]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000201333","archive":["Portico"],"relation":{},"ISSN":["0012-2823","1421-9867"],"issn-type":[{"value":"0012-2823","type":"print"},{"value":"1421-9867","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,2,5]]}}}
