Abstract

Most enterocutaneous fistulas are caused by complications of abdominal surgery that may result from anastomotic failure, poor blood supply, or iatrogenic bowel injuries. Mortality rates are high when associated sepsis and malnutrition are uncontrolled. Fistulas that occur late and those that recur spontaneously present more difficulty and may close spontaneously in less than 30% of cases. Mortality rates in patients with complex enterocutaneous fistulas may reach 60% to 80%. When traditional conservative surgeries of fistulous tract excision, bowel mobilization, and resection with primary end‐to‐end anastomosis fail, a more aggressive approach is required. The rectus abdominis muscle flap has been extensively studied and used in a wide variety of abdominal, vaginal, and perineal repairs. We report successful closure of complex enterocutaneous fistulas with a rectus abdominis muscle flap in a complicated case.
