Traumatic cloaca.

Deep laceration of the perineum after an obstetric injury may result in a cloacal deformity of the anus and vagina, causing complete fecal incontinence. A surgical technique consisting of reconstruction of the perineal body (perineoplasty) with puborectalis interposition and overlapping external sphincteroplasty is described to correct the defect and restore continence. This procedure has been used on 43 patients in a 10-year period with excellent anatomic and physiologic results.
