A novel ultrasound technique was used to determine OGJ opening, before and after atropine, in 12 normals. An ultrasound probe, a solid\u2010state pressure transducer and an infusion tube were placed inside a 20\u2010mm diameter bag, which was placed across the OGJ. At various bag pressures ultrasound transducer was pulled across the bag. Acquired B\u2010mode ultrasound images were converted into M\u2010mode image to display the oesophagus, OGJ and stomach. At low bag\u2010pressure (&lt;20\u2003mmHg), the OGJ but not oesophagus and stomach, is collapsed around the bag. Increasing bag pressure results in gradual opening of the OGJ from distal end. M\u2010mode image identified the narrowest region of OGJ and corresponding cross\u2010sectional area (CSA) was measured. Mean bag pressure to initial OGJ opening was 18\u2003mmHg. Linear relationship between bag\u2010pressure and OGJ\u2010CSA was observed. Atropine reduced opening bag pressure and shifted the OGJ pressure\u2010CSA curve upward without altering slope, i.e. compliance. Our novel ultrasound technique to study the OGJ opening function shows two distinct components; firstly, related to the tonic OGJ contraction and secondly, to passive or viscoelastic properties of the OGJ.<\/jats:p>","DOI":"10.1111\/j.1365-2982.2006.00763.x","type":"journal-article","created":{"date-parts":[[2006,3,8]],"date-time":"2006-03-08T09:55:50Z","timestamp":1141811750000},"page":"376-384","source":"Crossref","is-referenced-by-count":7,"title":["Oesophago\u2010gastric junction opening function: assessment using ultrasound imaging and the effects of atropine"],"prefix":"10.1111","volume":"18","author":[{"given":"J.","family":"Liu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.","family":"Takeda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"I.","family":"Dogan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"V.","family":"Bhargava","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.
