The clinical experience of 137 patients treated by one pediatric surge
on at HanYang University Hospital over 12 years was analyzed. The sex
ratio was 3.6:1 with male predominance. Neonatal Hirschsprung's diseas
e (HD) occurred in 70 cases (51.1%). One hundred fourteen cases (83.2%
) were short-segment and 23 cases (16.8%) were long-segment disease, o
f which 4 cases were total colon aganglionosis. Symptoms were abdomina
l distension, vomiting, constipation, and delayed passage of meconium.
Family history was noted in 4 cases: 3 involved siblings and 1 involv
ed relatives. All patients were male and had short-segment diseases. T
here were 3 pairs of monozygotic twins discordant for HD. Seventy-seve
n two-stage Duhamel operations were performed at the age of 121 +/- 41
.3 days. Primary Duhamel operations were performed on 30 children. Ano
rectal myectomies were performed on 12 cases of short rectal aganglion
osis. The incidence of enterocolitis was 25.5% preoperatively and 10.1
% postoperatively. Complications after the Duhamel operation were inte
stinal obstruction (3), wound disruption (4), and septum reformation (
3) with fecaloma formation in the blind rectal pouch. Rowel function w
as normalized within 3 months in 77.3% and within 1 year after operati
on in 91.6%. Duhamel operation with a GIA stapler after preliminary co
lostomy could be done at the age of 104 days on average with good func
tional results and with acceptable morbidity. Primary Duhamel operatio
n could be done safely on the patients whose conditions were diagnosed
after 90 days of life with good results. There was no mortality after
Duhamel operation. Copyright (C) 1995 by W.B. Saunders Company
