    Abstract:
    PURPOSE: This retrospective study was undertaken to evaluate the feasibility of primary anorectoplasty without a covering colostomy using the anterior sagittal anorectoplasty (ASARP) or posterior sagittal anorectoplasty (PSARP) technique in patients having vestibular and perineal fistulae, its complications, results, and remote outcome in our institute. METHODS: From January 2000 to June 2007, patients with vestibular and perineal fistulae subjected to single-stage surgical correction at our institute were reviewed retrospectively from the data available in hospital records and follow-up complaints of patients and their parents in the outpatient department. Patients who had undergone a staged repair were excluded from the study. All patients were assessed for immediate and delayed complications including continence of the neorectum. RESULTS: From January 2000 to June 2007, 123 patients having vestibular (94) and perineal fistulae (29), age range from 28 days to 10 years, were subjected to primary repair either by the ASARP (34) or PSARP (89) technique. Follow-up period ranged from 3 months to 7 years. Mortality was nil. Constipation (25.68%) was the major long-term problem. Incontinence occurred in 1 patient (1.85%), who also had associated sacral agenesis. A total of 98.15% of patients were continent with stool frequency of 1 to 4 per day. Recurrence of fistula (0.81%), anal stenosis (6.76%), mucosal prolapse (2.70%), and anterior migration of the neoanus (1.35%) were the other major problems. Other minor problems like wound infection, superficial wound dehiscence, transient constipation, and diarrhea, etc, were successfully managed by local wound care, antibiotics, laxatives, enema, anal dilatation, and dietary changes. CONCLUSION: Primary anorectoplasty either by PSARP or ASARP is feasible in vestibular and perineal fistulae without covering colostomy. Associated sacral agenesis/hypoplasia, redundant rectosigmoid or pouch colon, and wound infections with dehiscence are the major confounding factors affecting overall outcome. Better outcome in terms of continence can be achieved by careful surgical technique and follow-up along with proper toilet training. Complication rate was greater in cases of vestibular fistula than of perineal fistula, regardless of technique used. Some sort of laxatives and enema are often required. Dilatation of the neoanus for varying periods is also needed.
