Introduction and hypothesis
This video demonstrates a technique for using a pedicled gracilis muscle flap to repair rectovaginal fistula.
Methods
We present the case of a 48-year-old woman diagnosed with rectal cancer 2 years earlier. She underwent neoadjuvant chemoradiation followed by ultralow anterior resection. Six weeks after surgery, a fistula was identified at the anastomotic site. Preoperative planning with urogynecology, plastic surgery, and colon and rectal surgery teams deemed a pedicled gracilis muscle flap to be the best approach for this patient due to the rich blood supply and the patient’s prior history of pelvic irradiation. The gracilis muscle is suitable due to the proximity of its vascular pedicle to the perineum, length, and minimal functional donor-site morbidity. We discuss techniques used to interpose a gracilis muscle flap between the rectum and vagina to repair a rectovaginal fistula.
Conclusion
Using the gracilis muscle is a viable option for repairing rectovaginal fistulas, especially in the setting of prior pelvic radiation. A multispecialty approach may be beneficial in complex cases to determine the optimal approach for repair.
