| oesophageal stenosis | Stricture of the oesophagus. (12 Dec 1998) |
| oesophageal stricture, acute | A narrowing or closure of the normal opening of the swallowing tube leading to the stomach, usually caused by scarring from acid irritation. Acute, complete obstruction of the oesophagus occurs when food (usually meat) is lodged in the oesophageal stricture. Patients experience chest pain, and are unable to swallow saliva. Attempts to relieve the obstruction by inducing vomiting at home are usually unsuccessful. Patients with complete oesophageal obstruction can breathe, and are not at any risk of suffocation. Endoscopy is usually employed to retrieve the meat and relieve the obstruction. (12 Dec 1998) |
| oesophageal stricture, chronic | A longstanding narrowing or closure of the normal opening of the swallowing tube leading to the stomach, usually caused by scarring by acid irritation. Narrowing of the oesophagus. A common complication of chronic gastroesophageal reflux disease (GERD). Severa procedures are available for stretching (dilating) the strictures without having to resort to surgery. One of the procedures involves placing a deflated balloon across the stricture at the time of endoscopy. The balloon is then inflated, thereby opening the narrowingcaused by the stricture. Another method involves inserting tapered dilators of different sizes through the mouth into the oesophagus to dilate the stricture. (12 Dec 1998) |
| oesophageal strictures | <radiology> Lye (NaOH, Drano), acids, drugs, tetracycline, doxycycline (Vibramycin), quinidine, potassium (KCl), vitamin C (ascorbic acid), iron tablets (FeSO4), cromolyn sulfate (inhalant), Clinitest tablets (for urine testing of diabetics), epidermolysis bullosa (in kiddies!!), increased risk of oesophageal carcinoma (12 Dec 1998) |
| oesophageal trauma | <radiology> Emetic trauma: mucosal: Mallory-Weiss syndrome, intramural: intramural dissection, transmural: Boerhaave syndrome, non-emetic trauma: instrumentation, blunt trauma to chest, penetrating trauma, taco tear (12 Dec 1998) |
| oesophageal ulcer | A hole in the lining of the oesophagus 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) |
| oesophageal ulceration or diverticula | <radiology> Oesophagitis, reflux, infection, caustic agent, drug-induced, radiation, oesophageal diverticula, intramural pseudodiverticulosis (12 Dec 1998) |
| oesophageal ulcers | Circular erosions in the lining of the oesophagus. (27 Sep 1997) |
| oesophageal varices | Abnormal dilation of the veins in the oesophagus that occurs as the result of cirrhotic liver disease. Oesophageal varices are prone to bleed due to their fragility. See: cirrhosis. (27 Sep 1997) |
| oesophageal veins | Series of veins draining the submucous venous plexus of the oesophagus; proceding inferiorly from the cervical portion of the oesophagus, they drain to the inferior thyroid vein, the superior intercostal veins, the azygos, accessory hemiazygos and hemiazygos veins, all of which are ultimately tributaries of the superior vena cava; the most inferior oesophageal veins, from the cardiac portion of the oesophagus, drain via the oesophageal branches of the left gastric vein, a tributary of the portal vein. Thus, the submucosal veins of the inferior oesophagus form a portocaval anastomoses, and are subject to the formation of varicosities in portal hypertension. Synonym: venae oesophageae.

| 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) |
