OBJECTIVE: To investigate the effectiveness of endorectal advancement flaps for middle and low rectovaginal fistulas. METHODS: A retrospective cohort of 57 patients who underwent surgery via an endorectal advancement flap in the RVF between July 2007 and March 2022 was generated. The clinical features of the patients were reviewed. The associations between fistula closure and diverse clinical parameters, including age, body mass index, diameter of the fistula, prior repair, pathological type, diverting stoma and operative method, were analyzed. RESULTS: Congenital ( CONCLUSION: The endorectal advancement flap is safe and effective for removing simple rectovaginal fistulas at the middle and lower positions. A diameter greater than 1 cm is an independent risk factor for this surgical technique, and sphincteroplasty may be a better choice for this condition.
