| oesophageal web | A cribriform or web formation in the oesophagus caused by an irregular atrophy. (05 Mar 2000) |
|---|---|
| oesophageal webs and rings | <radiology> Congenital web, web secondary to bullous disease, cervical web, Plummer-Vinson (Patterson-Kelly) syndrome, mucosal (Schatzki) ring (12 Dec 1998) |
| tertiary oesophageal contractions | <radiology> Disordered up-and-down movement of bolus, 5-10% of normal adults in 4-6th decade, location: distal 2/3 of oesophagus aetiology: presbyesophagus, diffuse oesophageal spasm, hyperactive achalasia, neuromuscular disease: diabetes, Parkinsonism, ALS, MS, thyrotoxic myopathy, myotonic dystrophy, obstruction of cardia: neoplasm, distal oesophageal stricture, benign lesion, surgery (repair of HH) findings: spontaneous repetitive nonpropulsive contraction (yo-yo motion), corkscrew appearance, compartmentalization of barium (rosary bead, shish kebab) (12 Dec 1998) |
| tracheo-oesophageal fistula | <radiology> Type: Frequency, Description A: 10%, oesoph atresia without fistula B: 1%, oesoph atresia with upper fistula C: 80%, oesoph atresia with LOWER fistula D: 2%, K type: atresia with upper and lower fistulae E: 7%, H type See also: VATER syndrome (12 Dec 1998) |
| juxta-oesophageal pulmonary lymph nodes | Several nodes of the posterior mediastinal group located along either side of the oesophagus; they receive lymph from both the oesophagus and the lungs. Synonym: nodi lymphatici juxta-oesophageales pulmonales. (05 Mar 2000) |
| ulcer, oesophageal | A hole in the lining of the oesophagus (tube-like organ leading from the throat to the stomach) corroded by the acidic digestive juices secreted by the stomach cells. Ulcer formation is related to h. Pyloridus bacteria in the stomach, anti-inflammatory medications, and smoking cigarettes. Ulcer pain may not correlate with the presence or severity of ulceration. Diagnosis is made with barium X-ray or endoscopy. Complications of ulcers include bleeding and perforation. Treatment involves antibiotics to eradicate h. Pyloridus, eliminating risk factors, and preventing complications. (12 Dec 1998) |
| lower oesophageal sphincter | <anatomy> A muscular sphincter located at the junction of the oesophagus and the stomach. On closure the lower oesophageal sphincter prevents the back wash (reflux) of stomach acid into the oesophagus where it may damage the mucosa. See: gastrooesophageal reflux disease. (16 Mar 1998) |
