Rectovaginal Fistula Repair Following Vaginoplasty in Transgender Females: A Systematic Review of Surgical Techniques.

Abstract

Background: Rectovaginal fistula (RVF) remains a complex complication following gender-affirming vaginoplasty. This review aims to evaluate RVF repair techniques and outcomes following vaginoplasty. Methods: A systematic review was performed per PRISMA guidelines. Ovid MEDLINE, Ovid EMBASE, Cochrane, and Web of Science were queried for records pertaining to RVF repair following vaginoplasty. Study characteristics, operative details, and demographics were collected. Outcomes included RVF repair method, recurrence rate, and complications. Results: Among 282 screened citations, 17 articles representing 41 patients were included. Rectovaginal fistula repair methods identified included 4 conservative management approaches (n = 12 patients), primary closure with or without fistulectomy and ostomy (n = 22), 10 reconstructive surgical techniques (n = 18). The most common reconstructive techniques were V-Y full-thickness advancement with rectal flap (n = 5) and infragluteal fasciocutaneous flap (n = 4). Median time to recurrence was 6 months (interquartile range 7.5). Reported RVF repair complications included RVF recurrence (n = 5, 14.7%) and wound complication or dehiscence (n = 2, 5.88%). Three cases of RVF recurred after primary closure with or without fistulectomy and ostomy, while 2 cases of recurrence followed reconstruction. Conclusion: There remains a high level of variability in the approach to RVF repair following vaginoplasty. Reconstructive surgical techniques may be a more optimal solution without necessitating ostomies, but this decision must be considered in the context of RVF location, individual patient expectations, and clinical presentation.
