Purpose:
The aim of this study was to evaluate the clinical outcomes and postoperative anorectal function in the patients with high/intermediate imperforate anus (HIA/IIA) treated in our institution. In addition, we report our novel procedure, laparoscopically assisted anorectoplasty with anterior perineal incision (LAARP-API), which allows direct approach to the anterior edge of the puborectal sling and muscle complex, and is useful for the creation of a pulling-through route for the rectal pouch.
Methods:
From 1976 to 2016, 22 patients with HIA and 43 patients with IIA underwent sacroperineal/sacroabdominoperineal pull-through anorectoplasty (SP/SAP), Potts procedure (Potts), SP with API (SP-API) or LAARP-API. Clinical data and anorectal function of those patients were retrospectively evaluated using the Japanese clinical score.
Results:
Of the 22 cases of HIA, 15 were treated by SAP, 2 were SP and 5 were LAARP-API. Of the 43 cases of IIA, one was treated by SAP, 31 were SP, two were Potts and nine were SP-API. The mean score of anorectal function of HIA/IIA both increased with age. In IIA, the score after SP-API was significantly higher than the score after SP.
Conclusion:
Long-term outcomes of our anorectoplasty for HIA/IIA are good with excellent anorectal function score.
