XXXX in Waterston C neonates: a 30-year perspective.

@entity1 @entity154 @entity834 @entity3465 @entity55 @entity354 @entity4423
Two hundred and seventy-eight @entity1 with @entity154 have been managed at the Columbus @entity1 's Hospital since 1955. Fifty-four (20%) have been classified as high risk using Waterston's criteria of birth weight, @entity154 , and @entity55 . The @entity1 have been divided into group I (n = 27, 1955 to 1969) and group II (n = 27, 1970 to 1984) to reflect the onset of mechanical ventilation and effective neonatal intensive care. The mean birth weight of @entity1 in group II was significantly less than in group I (1,753 +/- 390 g v 1,950 +/- 505 g, P less than .05). The incidence of @entity3465 , measured by gestational age, has significantly increased with 9 of 27 (33%) @entity1 in group II and 2 of 27 (7%) @entity1 in group I less than 32 weeks gestation (P less than .05). The presence or severity of @entity154 was not significantly different in groups I and II. Twenty @entity1 in group I and 22 @entity1 in group II underwent definitive management of their @entity154 . Operative survival was 30% in group I and 74% in group II (P less than .05). Long-term survival was 15% in group I and 64% in group II (P less than .05). Early postoperative complications included @entity55 , @entity834 , or stricture. The most frequent complications in long-term follow-up were recurrent @entity55 , which were observed in 9 of 16 @entity1 . @entity4423 or @entity354 was documented in five of these @entity1 ; four were managed successfully with positional or pharmacologic manipulations while one required an antireflux procedure. Thirty percent (5/16) are asymptomatic.(ABSTRACT TRUNCATED AT 250 WORDS)
