Summary
Biological mesh interposition for rectovaginal fistula (RVF) showed disappointing results, with a low primary success rate. Further surgical interventions were required for most patients to achieve healing.
Area of Science:
- Surgical innovation
- Gastroenterology
- Pelvic reconstructive surgery
Background:
- Rectovaginal fistula (RVF) presents complex treatment challenges.
- Limited data exists on biological mesh interposition for RVF management.
Purpose of the Study:
- To evaluate the efficacy of biological mesh interposition in treating rectovaginal fistulas.
- To analyze surgical outcomes and complications associated with this technique.
Main Methods:
- Retrospective analysis of patients undergoing biological mesh interposition for RVF.
- Success defined by absence of fecal/mucous discharge and stoma.
Main Results:
- Ten patients with recurrent RVF (90%) were included; median 2.5 prior closure attempts.
- Primary success rate was 20%, with 70% achieving final success after reoperation.
- Postoperative morbidity occurred in 70% of patients, with 20% experiencing major complications.
Conclusions:
- Biological mesh interposition for RVF yielded disappointing results.
- Healing rates were lower compared to alternative methods like gracilis muscle interposition.
