Various distal pressures were applied to the experimental model filled with water, and the flow was recorded with a high-speed camera. The volume and maximum height of the refluxate through the pylori of two different sizes (7.5\u00a0mm, 15\u00a0mm) in two different postures (upright, semi-Fowler) was measured by analyzing the video clips.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>For the large pylorus setting, when the pressures of 20, 30, and 40\u00a0mmHg were applied in the upright position, the volumes of the refluxate in the RS\/PM tubes were 87.7\u2009\u00b1\u20091.1\/96.4\u2009\u00b1\u20091.7\u00a0mL, 150.8\u2009\u00b1\u20091.1\/158.0\u2009\u00b1\u20093.2\u00a0mL, and 156.8\u2009\u00b1\u20093.3\/198.0\u2009\u00b1\u20094.7\u00a0mL (p\u2009&lt;\u20090.05), and the maximum heights were 101.6\u2009\u00b1\u20094.8\/113.4\u2009\u00b1\u20092.9\u00a0mm, 151.4\u2009\u00b1\u20092.2\/165.4\u2009\u00b1\u20091.5\u00a0mm, and 166.1\u2009\u00b1\u20091.7\/193.7\u2009\u00b1\u20096.6\u00a0mm (p\u2009&lt;\u20090.05).
