Prognostic factors in neonatal intestinal obstruction: a prospective study of Nigerian newborns with bowel obstruction.

The management of neonatal intestinal obstruction in developing countries remains challenging, but the results are relatively less rewarding compared with results of treatment of this condition in industrialized countries. This study is an attempt to evaluate, using acceptable scientific methods, some of the factors that are believed to influence survival in neonatal intestinal obstruction, including those that are not peculiar to developing countries alone. Sixty-five babies treated for intestinal obstruction at the Lagos University Teaching Hospital, Lagos, Nigeria, formed the subjects for the study. The levels of obstruction, which were congenital in all cases, spanned the entire intestinal tract from the duodenum to the anus. Forty-one babies survived and 24 died, a survival rate of 63%. Employing Student's t test, there were no significant differences in the gestational age and birth weight between survivors and nonsurvivors, whereas significant differences do exist with respect to the age at operation and admission serum bicarbonate levels, P less than .05 and P less than .001, respectively. Analysis of the levels of obstruction and nature of operative procedure using the chi-square test shows no significant differences between the two groups. However, there is significant difference in the percentage of major associated congenital problems, P less than .01, which was higher in nonsurvivors.
