Abstract
Hirschsprung’s disease is a developmental disorder of the enteric nervous system and is characterized by absence of ganglion cells in the distal colon resulting in a functional obstruction. The aim of this study is to evaluate the postoperative outcome and to find the period required for normal defecation pattern after transanal endorectal pull-through
operation for congenital megacolon (stabilization period). Thirty cases diagnosed as congenital megacolon were subjected to full history taking with more consideration of the different items that are related to this study.
The history included Maternal history, present history that included delayed passage of meconium, bowel habits and nature of constipation. Abdominal examination was performed to detect sings of obstruction and per rectal examination to exclude any anomalies.
Investigations were performed in the form of routine labs; complete blood
picture, coagulation profile and urine analysis. Barium enema was done in all cases to show the extent of aganglionic segment. Rectal biopsies for suspicious cases were taken. The 30 patients underwent one-stage transanal endorectal pull-through (TERPT) operation for congenital megacolon
The most frequent complications reported in our study were entero-colitis that was relieved by conservative management, perianal excoriation that relieved by
topical measures in form of hygroscopic agents and zinc oxide in olive oil lotion, stricture in few patients which respond to repeated dilatation for 8 weeks and incontinence that was spontaneously improved within 10 weeks.
Failure was considered when there were persistent constipation, abdominal
distension, aganglionic proximal segment of the resected bowel and/or when barium enema revealed picture of megacolon.
