Various types of fistulas include: * Blind: Only one open end; may also be called sinus tracts. * Complete: Both internal and external openings. * Incomplete: An external skin opening that does not connect to any internal organ. Although most fistulas are in forms of a tube, some can also have multiple branches. Location Types of fistula can be described by their location. Anal fistulas connect between the epithelialized surface of the anal canal and the perianal skin. Anovaginal or rectovaginal fistulas occur when a hole develops between the anus or rectum and the vagina. Colovaginal fistulas occur between the colon and the vagina. Urinary tract fistulas are abnormal openings within the urinary tract or an abnormal connection between the urinary tract and another organ such as between the bladder and the uterus in a vesicouterine fistula, between the bladder and the vagina in a vesicovaginal fistula, and between the urethra and the vagina in 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 small intestine and the colon as a colocutaneous fistula. The following list is sorted by the International Statistical Classification of Diseases and Related Health Problems.

This results in improperly oxygenated blood. * (I67.1) Cerebral arteriovenous fistula, acquired * (I77.0) Arteriovenous fistula, acquired * (I77.2) Fistula of artery J: Diseases of the respiratory system * (J86.0) Pyothorax with fistula * (J95.0) Tracheoesophageal fistula, between the trachea and the esophagus. This may be congenital or acquired, for example as a complication of a tracheostomy. K: Diseases of the digestive system Duodeno Biliary Fistula * (K11.4) Salivary gland fistula * (K31.6) Fistula of stomach and duodenum * (K31.6) Gastrocolic fistula * (K31.6) Gastrojejunocolic fistula – after a Billroth II a fistula forms between the transverse colon and the upper jejunum (which, post Billroth II, is attached to the remainder of the stomach). Fecal matter passes improperly from the colon to the stomach and causes halitosis. * Enterocutaneous fistula: between the intestine and the skin surface, namely from the duodenum or the jejunum or the ileum. This definition excludes the fistulas arising from the colon or the appendix. * Gastric fistula: from the stomach to the skin surface * (K38.3) Fistula of appendix * () Anal and rectal fissures and fistulas * () Anal fistula * () Anorectal fistula (fecal fistula, fistula-in-ano): connecting the rectum or other anorectal area to the skin surface. This results in abnormal discharge of feces through an opening other than the anus. * (K63.2) Fistula of intestine * Enteroenteral fistula: between two parts of the intestine * (K82.3) Fistula of gallbladder * (K83.3) Fistula of bile duct * Biliary fistula: connecting the bile ducts to the skin surface, often caused by gallbladder surgery * Pancreatic fistula: between the pancreas and the exterior via the abdominal wall M: Diseases of the musculoskeletal system and connective tissue * (M25.1) Fistula of joint N: Diseases of the urogenital system * (N32.1) Vesicointestinal fistula * (N36.0) Urethral fistula * Innora:between the prostatic utricle and the outside of the body * (N64.0) Fistula of nipple * (N82) Fistulae involving female genital tract / Obstetric fistula * (N82.0) Vesicovaginal fistula: between the bladder and the vagina * (N82.1) Other female urinary-genital tract fistulae * Cervical fistula: abnormal opening in the cervix * (N82.2) Fistula of vagina to small intestine * Enterovaginal fistula: between the intestine and the vagina * (N82.3) Fistula of vagina to large intestine * Rectovaginal: between the rectum and the vagina * (N82.4) Other female intestinal-genital tract fistulae * (N82.5) Female genital tract-skin fistulae * (N82.8) Other female genital tract fistulae * (N82.9) Female genital tract fistula, unspecified Q: Congenital malformations, deformations and chromosomal abnormalities * (Q18.0) Sinus, fistula and cyst of branchial cleft * Congenital preauricular fistula: A small pit in front of the ear.
