Out of 182 naonatal surgical cases, which I had experienced between 1973 and 1987, 161 (excluding inguinal hernia, phimosis, accessory ear and superficial mass) were analized about the sex, diagnosis, birth weight, operative mortality and cause of death. As the birth weight decreases, the proprotion of female cases increses. Main diseases of the cases weighing more than 1,500g at birth were common congeninal anomalies such as imperforate anus, Hirschsprung's disease, intestinal atresia and Bochdalek hernia. On the other hand, congenital anomalies extremely decreased and perforation of the G-I tract increased in the cases weighing less than 1,500g at birth. Sixty percent of this goup was NEC. The mortality rate was tremendously different with birth weight (more than 1,500g ; 14% , less than 1,500g; 56%) . The main cause of death was sepsis arizing from perforation of the G-I tract (over 50% of died cases) .Improving the management for perforation of G-I tract is important to decrease the mortality rate at present. 1,500g (Birth weight) is proper dividing line for clinical analization of the Low-Birth-Weight surgical cases.
