ON RECENT PROGRESS IN PEDIATRIC SURGERY IN HOKKAIDO

Recent progress in pediatric surgery is most remarkable among the speciffc fields of surgery in Japan. In order to look back on this progress, I compared the therapeutic results of neonate and infant surgery in Hokkaido in the period between 1974－1978 with those between 1959－1965.
The operative rate of neonate during the recent 5 years has increased almost two times the rate of the past seven years (between 1959－1965). On the other hand, the recent mortality in neonate surgery has decreased to one half of the period between 1959－1965. Among the operative mortalities of the main pediatric diseases in the recent 5 years, it has decreased from 40% of the past seven years (1959－1965) to 27.3% in esophagus atresia, from 69.6% to 19.8% in congenital intestinal atresia, from 88.9% to 63.0% in gastrointestinal rupture, from 37.5% to 15.0% in congenital diaphragmatic hernia, and from 91. 7% to 58.3 % in omphalocele. In biliary atresia there was no improved case before 1965, but the rate of improvement is 31.4% since 1974.
The factors of such progress are recent improvement of diagnostic and operative techniques, preand postoperative management (for example, hyperalimentation etc.), and advancement in investigations of pathophysiology of pediatric surgical diseases.
