In this retrospective study carried out covering the period, 1978-1991, 62 neonates were seen, diagnosed and treated for intestinal atresia which included: duodenal atresia and stenosis, small bowel atresia and atresia of large bowel. Locations of obstruction were duodenal in 17 patients, jejunal in 25 patients, jejuno-ileal in 5 and colon in two. Duodenal atresia was noted in 9 infants and duodenal stenosis due to annular pancreas, Ladd's bands with malrotation of bowel in 8. Associated anomalies which were observed were anorectal malformations in 2 and malrotation in 2 infants. Birth weights ranged from 1450 gm to 3000 gm. Prematurity was recorded in 11 infants. Diagnosis of intestinal atresia in our patients was made clinically and radiologically. Intestinal atresia in neonates was differentiated from other causes of obstruction such as Meconium Ileus, Hirschsprung's disease, neonatal volvulus, rectal atresia in anorectal malformations. Treatment of infants with intestinal atresia was surgical. Surgical techniques used depended on pathological findings. In 36 patients, complications such as functional obstructions with vomiting and failure to thrive, malabsorption, aspiration, bronchopneumonia, sepsis were observed. Overall mortality rate in our cases was 25 (41.9%) out of 62 patients.
