ANORECTAL RECONSTRUCTION BY ELECTROSTIMULATED GRACILOPLASTY AS PART OF ABDOMINOPERINEAL RESECTION

AIMS: To report the outcomes of anorectal reconstruction by electrostimulated graciloplasty as part of abdominoperineal resection, on data prospectively collected over 10 years. PATIENTS AND METHODS: Twenty-three abdominoperineal resections were associated to coloperineal pull through, double graciloplasty and loop abdominal stoma. Fifteen patients also received an implantable pulse generator, either for unsatisfactory result after external-source intermittent electrostimulation and biofeedback (five cases) or during graciloplasty (10 cases). Follow-up was to a maximum of 10 years. Functional outcome was followed up in sixteen patients who underwent stoma takedown. RESULTS: Mean actuarial survival at 5 years was 72.3%. Satisfactory results (score < or =8) occurred in 75% of patients (three without and 13 with stimulator) in the early stages, decreasing to 57% at 1 year and gradually increasing up to 100% at 5 years and over. CONCLUSIONS: Total anorectal reconstruction yields a good functional outcome over time. Thus, despite, and because of, a high complication rate and a great drain on resources, it should be considered a suitable procedure only for selected, strongly motivated patients.
