Fistula- overview, causes, symptoms, types, and treatment

A fistula is an abnormal connection between two organs or veins that is formed by a tunnel-like opening. Fistulas can develop in a variety of locations across the body. Fistulas involving the vaginal and urinary systems are the most prevalent in women and are caused by protracted or obstructed childbirth, pelvic surgery damage, infection, inflammation, or radiation treatment in the pelvis or genital area.



FISTULAS TYPES

ANAL AND PERIANAL FISTULAS

  • An abnormal connection between the anal canal's epithelialized surface and the perianal skin.
  • An anorectal fistula is a connection between the anal canal and the skin around the anal entrance.
  • When a hole develops between the rectum or anus and the vagina, it is called a rectovaginal or anovaginal fistula.
  • A colovaginal fistula is a connection between the colon and the vagina.

URINARY TRACT FISTULAS

  • Openings within a urinary tract organ that are aberrant, or a link between a urinary tract organ and another organ that is abnormal.
  • The bladder and the uterus form a vesicouterine fistula.
  • A vesicovaginal fistula is formed when a hole forms between the bladder and the vagina.
  • The urethrovaginal fistula is a connection between the urethra and the vagina.

OTHER TYPES

  • An enteroenteric fistula is a connection between two sections of the intestine.
  • An enterocutaneous or colocutaneous fistula is a connection between the small intestine and the skin, or between the colon and the skin.
  • Fistulas, if left untreated, can be distressing, debilitating, and cause more injury to your health. Fistulas are linked to nerve injury, infection, and kidney failure.

What causes fistula

  • The creation of a fistula on the human body can be caused by a number of factors. As previously noted, some may form spontaneously, while others may be the result of an injury or surgery.
  • The most frequent type of fistula, anal fistula, can develop gradually over time. A fistula can sometimes occur between the gut and the vagina. This is also natural.
  • Those suffering from gastrointestinal disorders such as Crohn's disease, colitis, and irritable bowel syndrome, on the other hand, are more likely to develop a fistula near the anus. After childbirth, women may also develop a fistula between the anus and the vagina.
