Traumatic deficient perineum: surgical management and outcome from a single center.

Abstract

Deficient perineum is a disruption of the perineal body and distal rectovaginal septum presenting with anal incontinence and a range of urogenital symptoms. There is scarce reported outcome of this condition with management often delayed and with a variety of surgical alternatives. This study aims to determine faecal continence outcomes after long-term surgical repair. Patients were included for analysis after surgical repair between 1989 and 2012. Cases were preoperatively assessed by endosonography and anorectal manometry with a record of their continence with the Cleveland Clinic Incontinence Score (CCIS). Surgical repair comprised an overlapping repair of the external anal sphincter (EAS) with levatorplasty. There was selective use of internal anal sphincter (IAS) suture and/or advancement perineoplasty for soft tissue reconstruction. Patients were clinically evaluated for functional outcomes with comparison of their postoperative CCIS. There were 20 patients (median age 55.5years; range 29-81years) with a median duration of incontinence symptoms of 174 (range 1-540)months. All patients had an EAS and IAS defect with 14 (70%) undergoing an IAS suture and 10 (50%) a Corman-style anoplasty. Over a median follow-up of 137.2 (range 13-322)months, there was a significant decrease in the recorded median preoperative vs. postoperative CCIS 18, range 13-20 vs. 2, range 0-10, respectively; p < 0.001) with 18 (90%) satisfied with the functional outcome. Faecal diversion was not used in any of the patients. Experienced delayed repair of a traumatic cloaca is associated with an acceptable functional outcome at medium- to long-term follow-up.
