| tracheoesophageal fistula | A congenital anomaly where the upper oesophagus ends (atresia) and does not connect with the stomach and the lower oesophagus connects to the trachea (tracheoesophageal fistula). A common complication seen shortly after birth is an aspiration pneumonia. Infants will demonstrate excessive salivation, gagging and coughing with feeding, poor feeding and a bluish discolouration to the skin (cyanosis). Treatment involves the surgical repair of the oesophagus before the child can take anything by mouth. (27 Sep 1997) |

| H-type tracheoesophageal fistula | <gastroenterology, surgery> A rare form of congenital tracheoesophageal fistula in which there is no oesophageal atresia, manifest as aspiration pneumonias. Synonym: H-type tracheoesophageal fistula. (05 Mar 2000) |
|---|---|
| tracheoesophageal | Relating to the trachea and the oesophagus. (05 Mar 2000) |
| tracheoesophageal puncture | A small opening made by a surgeon between the oesophagus and the trachea. A valve keeps food out of the trachea but lets air into the oesophagus for oesophageal speech. (12 Dec 1998) |
| tracheoesophageal speech | A form of alaryngeal speech obtained by a surgical technique which creates a shunt between trachea and oesophagus, allowing pulmonary air to generate upper oesophageal and pharyngeal mucosal vibrations as a substitute for vocal cord vibrations when the larynx is surgically removed. (05 Mar 2000) |
| abdominal fistula | A tract leading from one of the abdominal viscera to the external surface. (05 Mar 2000) |
| amphibolic fistula | A complete anal fistula opening both externally and internally. (05 Mar 2000) |
| anal fistula | A fistula opening at or near the anus; usually, but not always, opening into the rectum above the internal sphincter. (05 Mar 2000) |
| anorectal fistula | <surgery> An abnormal tube-like passage connecting the anal canal and the rectum. May result from injuries, abscesses or inflammatory processes (for example cancer, Crohn's disease). (27 Sep 1997) |
| arterio-arterial fistula | Abnormal communication between two arteries. It may result from injury or occur as a congenital abnormality. (12 Dec 1998) |
| arteriovenous fistula | <surgery> The surgical joining of an artery and a vein under the skin for the purpose of haemodialysis. Larger arteriovenous shunts can place strain on the heart since arterial blood is diverted back to the venous circulation before it has a chance to deliver nutrients and oxygen to the body tissues. (27 Sep 1997) |
| A-V fistula | <surgery> The surgical joining of an artery and a vein under the skin for the purpose of haemodialysis. Larger arteriovenous shunts can place strain on the heart since arterial blood is diverted back to the venous circulation before it has a chance to deliver nutrients and oxygen to the body tissues. (27 Sep 1997) |
| biliary fistula | Abnormal passage communicating with the biliary tract. (12 Dec 1998) |
| bladder fistula | An abnormal passage in the bladder or between the bladder and another organ. (12 Dec 1998) |
| blind fistula | A fistula that ends in a cul-de-sac, being open at one extremity only. Synonym: incomplete fistula. (05 Mar 2000) |
| B-P fistula | Communication between a bronchus and the pleural cavity; usually caused by necrotizing pneumonia or empyema; also may follow pulmonary surgery or irradiation. Synonym: B-P fistula. (05 Mar 2000) |
