Martius advancement flap for low rectovaginal fistula: Short- and long-term results

Abstract

Aim Many surgical approaches have been described for the treatment of low rectovaginal fistulae (LRVF); however, all are associated with a high recurrence rate and a poor function. The Martius flap technique was first described in 1928 and has since been modified for the treatment of LRVF. The aims of this study were to evaluate the short- and long-term results of the Martius flap procedure. Method Twenty patients who underwent the Martius flap procedure between 2000 and 2010 were retrospectively included. Operative results and morbidity were evaluated. Quality of life (SF-12 score), quality of sexual life [Female Sexual Function Index (FSFI) score] and anal continence (Wexner score) were determined. Results Crohn's disease was the predominant aetiology (n=8, 40%). The Martius flap was mostly harvested from the left side (n=14, 66.7%). The morbidity rate was 15% (n=3), and the mean hospital stay was 7.7±3.7days. At a mean follow up of 35months, the success rate was 65%. Seven patients still had an LRVF: in patients with Crohn's disease the success rate was 50% (4/8). Fifteen patients (75%) answered the three questionnaires. Quality of life score was in the normal range: physical component summary score (PCS: 46.7±9) and mental component summary score (MCS: 44.7±11.3). The median (range) FSFI score was 5 (2-31.7). Eight patients (53%) deemed cured suffered no incontinence. The Wexner score was significantly higher in the presence of a persisting LRVF (2.6±5.5 vs 13.4±3.78) (P=0.0018). Use of a right-sided flap was associated with a higher success rate (P=0.0442). Conclusion The Martius flap procedure for LRVF, had a success rate of about 60% and a low morbidity. © 2011 The Authors.
