AimThe rectovaginal fistula (RVF) is relatively uncommon and by clinical manifestations grave illness. The surgery treatment of RVF is extremely demanding and represents the subject of frustration for many surgeons. Miscellaneous etiology of RVF and various heights of fistula in a rectovaginal septum are crucial for the choice of surgical procedure. Despite targeted treatment, more than one-half of rectovaginal fistulas recurs. We evaluated the frequency of recurrences after surgical treatment by modified Martius graft and its influence on continence and quality of life. The necessity of concomitant colostomy when performing modified Martius graft was the secondary aim.MethodWe collected and analyzed 8 years of data from our patient database. There were admitted 21 female patients with diagnosis RVF to the Surgery department of Faculty Hospital Trnava. Unfortunately, only 5 patients, concerning the etiology of disease and clinical state, were indicated for surgery by modified Martius graft. All RVFs were low and a defect in the rectovaginal septum wouldn't exceed 1.5 cm in diameter.ResultsDue to the small sample and non-confirmation of normality in all variables, nonparametric comparison tests were chosen for paired samples differences. We used the Wilcoxon sign-rank test and counted the effect sizes expressed the success of the treatment. Each female patient with low RVF included in this study has healed. The mean value of a complete healing of RVF in our cohort was 12 weeks. We had discovered one recurrence after surgery, that was successfully repaired by contralateral modified Martius graft. The significant decrease of Wexner fecal incontinence score in the observed group (p<0.05, r=0.639) and slightly elevated Cleveland Clinic Constipation Scoring System (p<0.05, r=-0.577) were confirmed. The protective colostomy was performed just once. Only two sections of the SF-36 Health Survey - the physical functioning and the bodily pain, were without significant changes. The rest of the watching sections of SF-36 have changed significantly.ConclusionTreatment of low rectovaginal fistulas (LRVF) by modified Martius graft is followed by a low percentage of recurrences. It should be the first-line therapy in the algorithm of surgical treatment of LRVF, without the necessity of protective colostomy (Tab. 2, Fig. 3, Ref. 27).
