SubjectNCEBP 2: Evaluation of complex medical interventions
BACKGROUND/PURPOSE: Usually, anorectal malformations (ARM) are treated in 2 or 3 stages for fear of disturbed wound healing and subsequent damage to the anal sphincter complex. The aim of this study was to assess the feasibility, safety, advantages, and follow-up of an anterior or posterior sagittal anorectoplasty in low-type ARM (rectoperineal or rectovestibular), performed without colostomy. MATERIALS AND METHODS: Prospective collection of data regarding demographics, VACTERL (Vertebral-, Anal-, Cardiac-, Tracheo-Esophageal-, Renal-, Limb malformations) screening, perioperative measurements, surgeons, and complications. RESULTS: In 35 consecutive children (13 boys, 22 girls), repair of a low-type ARM was performed without colostomy. There were 13 boys and 10 girls with a rectoperineal and 12 girls with a rectovestibular fistula. The median age at operation was 4 months (range, 0-73 months); 34% being performed in the newborn period. Seventeen children had one or more other congenital anomaly. Preoperatively, all patients had rectal washouts with oral and rectal neomycin, and perioperative antibiotics, either 24 h (prophylaxis) or for 2 to 5 days. An anterior or posterior sagittal anorectoplasty was performed. Postoperatively, 9 children had no enteral feeding and total parenteral nutrition (TPN). All children had postoperative anal dilatations according to the Pena scheme. Two children (both with rectoperineal fistula) had a wound abscess; in the first child (with renal insufficiency), a colostomy was performed and in the other child a successful correction of the anoplasty was done. In 7 children (4 rectoperineal, 3 rectovestibular fistulae), the anus eventually healed after minor wound dehiscence. There was 1 anal stricture, after a median follow up of 14 months (range, 1-84 mo). After therapeutic antibiotics (2-5 days), 11% (2/18) had some degree of wound infection, versus 41% (7/17) after either no antibiotics or after prophylactic antibiotics (24 hours). Patients with TPN did not seem to profit with regard to wound healing and one patient experienced a central line related sepsis. At last follow-up, 12 children needed regular laxatives and/or enemas. Anal dilatations were well accepted above 6 months, and a trend was seen towards less need for laxatives when dilatations were continued longer. CONCLUSION: Repair of a low-type ARM without colostomy, with therapeutic antibiotics, and followed by a long period of postoperative anal dilatations has low morbidity and good outcome, which does not seem to be improved with TPN.
