    Abstract:
    Fifty-two women with a rectovaginal fistula were managed over a period of 15 years. All the fistulae were caused by obstetric injury commonly resulting from breakdown of the repair of complete perineal tears or from unrecognised injury during forceps or precipitate delivery. In five patients the fistula healed spontaneously within 12 weeks of the injury. Thirty-nine patients underwent transvaginal purse-string repair by standard technique and eight patients had perineoproctotomy and sphincteroplasty for large fistulae associated with anal incontinence. Surgical repair was successful in all the 47 patients including two patients who had previous failed repair elsewhere. The routine postoperative follow-up period of the patients ranged between 6 months and 8 years. There were no residual symptoms of anal sphincter weakness in the patients treated with transvaginal purse-string repair. Two of the patients who underwent perineoproctotomy and sphincteroplasty complained of varying degrees of postoperative incontinence of flatus that resolved by 8 weeks postoperation. In our experience the transvaginal purse-string method of repair for small, low rectovaginal fistulae proved highly satisfactory with 100% cure rate. Perineoproctotomy and sphincteroplasty for larger fistulae associated with anal incompetence was equally successful with minimal postoperative morbidity.
