In anatomy, a fistula (pl.: fistulas or fistulae /-li, -laɪ/; from Latin fistula, "tube, pipe") is an abnormal connection (i.e. tube) joining two hollow spaces (technically, two epithelialized surfaces), such as blood vessels, intestines, or other hollow organs to each other, often resulting in an abnormal flow of fluid from one space to the other.[2][3][4] An anal fistula connects the anal canal to the perianal skin. An anovaginal or rectovaginal fistula is a hole joining the anus or rectum to the vagina. A colovaginal fistula joins the space in the colon to that in the vagina. A urinary tract fistula is an abnormal opening in the urinary tract or an abnormal connection between the urinary tract and another organ. An abnormal communication (i.e. hole or tube) between the bladder and the uterus is called a vesicouterine fistula, while if it is between the bladder and the vagina it is known as a vesicovaginal fistula, and if between the urethra and the vagina: a urethrovaginal fistula. When occurring between two parts of the intestine, it is known as an enteroenteral fistula, between the small intestine and the skin as an enterocutaneous fistula, and between the colon and the skin as a colocutaneous fistula.[3]
A fistula can result from an infection, inflammation, injury or surgery.[5] Sometimes a fistula is deliberately surgically created as part of a treatment, for example in the case of an arteriovenous fistula for hemodialysis.[6]
The treatment for a fistula varies depending on the cause and extent of the fistula, but often involves surgical intervention combined with antibiotic therapy. In some cases the fistula is temporarily covered using a fibrin glue or plug. A catheter may be required to drain a fistula.[3]
Globally, every year between 50,000 and 100,000 women are affected by one or more fistulas relating to childbirth.[7] In botany, the term is most common in its adjectival forms, where it is used in binomial names to refer to a species that is distinguished by one or more hollow or tubular structures. Monarda fistulosa, for example, has tubular flowers.[8] The term was first used in the 14th century.[2]
