عنوان مقاله [English]
Hirschsprung's disease is a developmental disorder of the enteric nervous system, characterized by functional obstruction. Absence of ganglion cells in the distal colon resulting in a functional obstruction. The aim of this study was to evaluate the results and complications of one-stage transanal endorectal pull-through (OTEPT) in the management of patients with Hirschsprung's disease.
Materials and Methods
A total of 40 children (31 boys and 9 girls) aged 3 days to 60 months underwent OTEPT procedure over a period of two-years at Dr. Sheikh pediatric Hospital. This study was approved by the local committee of Medical Ethics. Median follow up period was 9.10 months (range, 3 to 33 months).
Mean operation time recorded 101.60 mins (range, 25 to 270 minutes). Hirschsprung's disease developed conventional in 55% (short segment in 30%), Ultra-short in 32.5% and long segment in 12.5%. Mean length of resected bowel measured 17.31 cm, 2 patients underwent laparatomy because of extension of aganglionic segment beyond the sigmoid colon. Mean NPO time and need to rectal tube after the operation were 4.35 and 4.41 days, respectively. 8 patients required urinary catheters after the operation with the mean remaining time of 3.30 days, 20% needed ICU care after surgery and mean hospital stay was 5.76 days. Post-operative complications included entrocolitis (n=2) and abdominal distension (n=1). One patient expired due to non surgical reason (heart failure).
OTEPT procedure is a safe method with low incidence of postoperative complications. In Hirschsprung's disease confined to the rectosigmoid region, the hazard and morbidities associated with laparatomy and colostomy are avoided with this technique.
