Appendico-vesicocolonic fistula: A case report and review of literature

Incidental Appendico-Ileal Fistula in a Patient With Adhesive Intestinal Obstruction: A Case Report

“…The appendix can develop fistulous communication with any intra-abdominal organ, including the colon, rectum, ileum, urinary bladder, ureter, uterus, vagina, etc. [6][7][8][9][10][11]. Appendico-ileal fistula is very rare with anecdotal case reports in English literature [6,8,9].…”

“…Colonoscopy is a useful investigation to detect colonic pathologies, visualization of the appendiceal orifice, and the opening of the fistulous tract in case of appendico-colonic or appendico-rectal fistula [10]. Cystoscopy helps identify the site of an appendico-vesical fistula [11].…”

“…The crucial steps of the surgery include the dismantling of the fistula, appendectomy, and primary repair of the affected organs, such as the ileum, vagina, or bladder. The surgery can be performed by minimally invasive techniques [11], but in most of the previous reports, open surgery was performed due to its complexity [10]. Alternatively, percutaneous drainage can be offered to patients with appendicular abscesses who are hemodynamically unstable or not suitable for emergency surgery [12].…”

“…The exact incidence is not known as there are only case reports and series published in the English literature. Depending on the affected organ, fistulous communication has been reported between the appendix and urinary bladder, ileum, rectum, and vagina [6][7][8][9][10][11]. It can be due to acute or chronic appendicitis, cystic fibrosis, or Crohn's disease.…”
