Origin of fistulaMiddle English from Latin
(plural fistulas or fistulae or fistulæ)
- (medicine): The skin is regarded as an organ, so the definition includes the abnormal connection of an intenal organ to the body's exterior (as in, for example, enterocutaneous fistulas).
- Sometimes, a fistula will be intentionally created; for example, an arteriovenous fistula is sometimes created to ease the treatment of a patient with end stage renal failure.
OriginSee also: fístula
