Treatment and postoperative complication of 420 patients with congenital megacolon.
OBJECTIVE
Hirschprung's disease is still one of the most important problems of pediatric surgery and its treatment has its own different complications and difficulties. Therefore, pediatric surgeons use different methods in each case. The objective of this study was to review the advantages and disadvantages of the Swenson's procedure over the past 20-years.


METHODS
In this survey, we reported 420 patients who in a 20-year interval (from 1981-2000) with the net diagnosis of Hirschprung's disease, were admitted to the pediatric surgery ward of Taleghani Medical Center, Tehran, Iran and operated on by Swenson's procedure. This survey has been carried out in 2 parts with descriptional method using patients' files and analytical method by using patients' observation and questionnaires. In the first step, they were 420 patients and in second step 216 patients were studied and the results of the first 10 years (190 cases) and the results of the second 10 years (230 cases) were analyzed alone and compared with each.


RESULTS
The results revealed wound infection in 17 cases in the first 10 years (14.2%), with18 cases in the second (7.9%) giving a mean of 10.7%. Anastomosis leakage was 6.8% in the first and 2.2% in the second 10 years with a mean of 4.2%. Septicemia was 3.6% in the first and 0.9% in the second period with a mean of 4%. Intestinal obstruction was 4.2% in the first and 2.1% in the second 10 years with a mean of 3%. There was no mortality during the surgery and for one month after. The results of late complications are: rectal anastomosis stricture, 13% in the first and 3% in the second 10 years with a mean of 7.6%; inguinal hernia of 1.6% in the first and 0.4% in the second period with a mean of 1% and finally, the death rate due to enterocolitis was 1.6% in the first and 0.9% in the second 10 years. Altogether, 87% of patients and their parents were satisfied with bowel habits after operation; 10% were relatively satisfied and 3% were not satisfied at all. Age distribution at the time of diagnosis: 50% of 0-1 months; 23% of 1-12 months and 27% were above one-year-old. Three hundred and eleven patients (74%) were male and 109 (26%) were female. The youngest patient was 3-days-old and the oldest was a 14-year and 3-month-old boy. The most common denerved part of the intestine was sigmoid colon with 54.4% prevalence.


CONCLUSIONS
Our results show that Swenson's method is a successful procedure in the treatment of Hirschprung's disease.
