| oesophagogastric orifice | The trumpet-shaped opening of the oesophagus into the stomach. Synonym: ostium cardiacum, cardiac opening, oesophagogastric orifice. (05 Mar 2000) |
| oesophagogastric ring | A congenital anatomic narrowing in the lower 1/3 of the oesophagus that is the result of inappropriate embryological development of the oesophagus. Symptoms include difficulty swallowing and chest pain (under the sternum). Treatment involves the use of a fibreoptic endoscope using a dilator to open up the narrowed segment of the oesophagus. (27 Sep 1997) |
| oesophagogastric vestibule | The dilated aboral portion of the oesophagus, just above the cardiac orifice; usually it corresponds to the lumen of abdominal part of the oesophagus although its relation to the diaphragm is variable. Synonym: oesophagogastric vestibule. (05 Mar 2000) |
| oesophagogastroanastomosis | Anastomosis of oesophagus to stomach, usually following oesophagogastrectomy. Synonym: oesophagogastroanastomosis, gastroesophagostomy. Origin: oesophagus + G. Gaster, stomach, + stoma, mouth (05 Mar 2000) |
| oesophagogastroduodenoscopy | A procedure that enables the examiner (usually a gastroenterologist ) to examine the oesophagus ( swallowing tube), stomach, and duodenum ( first portion of small bowel ) using a thin flexible tube (a scope ) that can be looked through or seen on a TV monitor. Also called upper endoscopy (12 Dec 1998) |
| oesophagogastromyotomy | Treatment of oesophageal achalasia by longitudinal division of the lowest part of the oesophageal muscle down to the submucosal layer; some muscle fibres of the cardia may also be divided. Synonym: cardiomyotomy, oesophagogastromyotomy, Heller myotomy. Origin: oesophagus + G. Mys, muscle, + tome, incision (05 Mar 2000) |
| oesophagogastroplasty | An operation on the cardia of the stomach. Synonym: oesophagogastroplasty. Origin: cardio-+ G. Plastos, formed (05 Mar 2000) |
| oesophagogastrostomy | Anastomosis of oesophagus to stomach, usually following oesophagogastrectomy. Synonym: oesophagogastroanastomosis, gastroesophagostomy. Origin: oesophagus + G. Gaster, stomach, + stoma, mouth (05 Mar 2000) |
| oesophagogram | A roentgenogram of the oesophagus. (05 Mar 2000) |

| oesophagology | Study of the structure, physiology, and diseases of the oesophagus. Origin: oesophagus + G. Logos, study (05 Mar 2000) |
| oesophagomalacia | Softening of the walls of the oesophagus. Origin: oesophagus + G. Malakia, softness (05 Mar 2000) |
| oesophagomycosis | A fungous infection of the oesophagus. Origin: oesophagus + G. Mykes, fungus, + -osis, condition (05 Mar 2000) |
| oesophagomyotomy | Treatment of oesophageal achalasia by longitudinal division of the lowest part of the oesophageal muscle down to the submucosal layer; some muscle fibres of the cardia may also be divided. Synonym: cardiomyotomy, oesophagogastromyotomy, Heller myotomy. Origin: oesophagus + G. Mys, muscle, + tome, incision (05 Mar 2000) |
