Abstract

Background:

Anterior sagittal anorectoplasty (ASARP) has been a standardised operative treatment for anorectal malformation (ARM). This retrospective study was undertaken to evaluate patients with perineal fistula (PF) and vestibular fistula (VF) treated by ASARP in our institution.

Patients and Methods:

Twenty patients (PF, n = 14; male, n = 8 and female, n = 6 and VF, n = 6) were evaluated. Eighteen patients underwent primary ASARP without protective colostomy. Two patients underwent colostomy because of intestinal atresia and suspected of other type ARM. The age range of operation was from 4 months to 5.0 years. Sixteen patients (PF, n = 13; male, n = 7 and female n = 6 and VF, n = 3) over 3 years of age were evaluated according to the Krickenbeck classification.

Results:

Operative complications occurred in one patient. Minor wound dehiscence occurred in six patients. Mucosal prolapse occurred in two patients. According to the Krickenbeck classification, amongst male patients with PF, all patients had voluntary bowel movements (VBMs) and two patients had Grade 1 soiling, while four patients had Grade 2 constipation. Amongst female patients with PF, all patients had VBM and no soiling, one patient had Grade 1 and two patients had Grade 2 constipation. In patients with VF, one patient was continent with Grade 1 soiling. One patient had Grade 2 and two patients had Grade 3 constipation.

Conclusions:

ASARP without colostomy carried a risk of wound dehiscence. The ASARP technique provided normal or moderate outcomes for VBM and soiling. However, in about half of patients, defecation management with laxative therapy was required to achieve a normal condition.
