Causes of Fitsula

Fistula is an abnormal connection developed between two organs, glands, arteries or veins. It usually develops in response to clogged glands or abscesses.

  • Crohn’s disease: it is a gastrointestinal disorder known as inflammatory bowel disease. This causes pain and swelling of lining of gastrointestinal tract. Development of gastro-intestinal fistula is one of the complications of IBD. Abscess formation causes development of abnormal opening into gastrointestinal tract that drains out the excess fluid formed.
  • Exposure to Radiation: Treatment of cancer involves radiation therapy to kill the abnormal cells produced due to hyper-proliferation of the cells. Fistula may develop due to cancer cells itself or it can be an aftermath result of treatment of cancer. 
  • Sexually transmitted disease: Sexually transmitted diseases cause viral infection and decrease the immunity of the body. Thus, making the body more susceptible to develop infections. Common STD’s like Syphyillis and Chlamydia are more prone for the formation of anal fistula to deplete the excess formed fluid.   
  • Abnormal growth of cells: Metastasis causes formation of fistula. The abnormal growth of cells within the glands or in the visceral organs leads to the formation of fistula. Abnormal growth may result in the formation of fistula or the abnormal growth may be due to the formation of fistula.
  • Diverticulitis: diverticulitis causes formation of fistula between the colon and bladder or between colon and vagina in ladies. The abscess ruptures into the adjacent organs or veins that lead to the formation of diverticulitis fistula. 
  • Trauma: in a physical trauma, the knife or gun (bullet) tears the skin layers and enters the abdomen that results in the formation of fistula.
  • Clogged glands: the internal glands are filled with excess fluid, fistulas formed to drain out the excess fluid clogged.
  • Abscesses: formation of fistula is an advantage for proper functioning of the glands or organs. The excess fluid or pus formed within the organ or gland oozes out into external environment through this tunnel like structure called fistula.
  • Surgery: perforation to the membranes or glands result in the formation of fistula.  Most of the times fistula is formed post-surgery or operation. Cancer surgeries or gastrointestinal surgery initiates the formation of fistula.
  • Malnutrition: an Enterocutaneous fistula is an abnormal development of tunnel like structure between stomach, small intestine, large intestine and the skin facilitates the passage of gastro-intestinal contents to flow onto the skin. Body nutrition is managed by total parenteral nutrition, calories and proteins replacement.
