ABSTRACT
A Clinic study was made on 140 cases of acute appendicitis in children under the age of 15 which were treated at National Seoul Hospital during the past 10 years from Jan. 1971 to dec. 1980. The following results were obtained. 1) The disease is relatively uncommon under the age of 6, and showed a progressive increase from 6 to 15 years old. The ratio between male and female was within 1.5:1 and there was no significant difference in the seasonal distribution. 2) The duration from onset to admission was within 24 hours in imperforated group and within 48 hours in a perforated one. 3) The over-all perforation rate was 13.6%. 4) The average leukocyte count was 10,000~15,000/mm and leukocytosis was noted in 70.7%. In 56.7% of cases neutrophil count was above 75%. 5) The complications occurred mainly in a perforated group and they were wound infection. 6) The average hospital days were 5.3days in an imperforated group and 10.2 days in a perforated one. 7) There was no mortality.
