Popis: Introduction Rectovaginal fistulas (RVFs) account for approximately 40% of anorectal complications from obstetrical trauma. Treatment can be challenging requiring multiple surgical repairs. Interposition of healthy transposed tissue (lotus or Martius flap or gracilis muscle) has been used for recurrent RVF. We aimed to review our experience with gracilis muscle interposition (GMI) for post-partum RVF. Methods A retrospective analysis of patients who underwent GMI for post-partum RVF from February 1995 to December 2019 was undertaken. Patient demographics, number of prior treatments, comorbidities, tobacco use, postoperative complications, additional procedures, and outcome were assessed. Success was defined as absence of leakage from the repair site after stoma reversal. Results Six of 119 patients who underwent GMI did so for recurrent post-partum RVF. Median age was 34.2 (28-48) years. All patients had at least 1 previously failed procedure [median: 3 (1-7)] including endorectal advancement flap, fistulotomy, vaginoplasty, mesh interposition, and sphincteroplasty. All patients underwent fecal diversion prior to or at initial procedure. Success was achieved in 4/6 (66.7%) patients; 2 underwent further procedures (1 fistulotomy and 1 rectal flap advancement) for a final 100% success rate as all ileostomies were reversed. Morbidity was reported in 3 (50%) patients, including wound dehiscence, delayed rectoperineal fistula, and granuloma formation in one each, all managed without surgery. There was no morbidity related to stoma closure. Conclusions Gracilis muscle interposition is a valuable tool for recurrent post-partum RVF. Our ultimate success rate in this very small series was 100% with a relatively low morbidity rate.
