Does Down syndrome affect the outcome of congenital duodenal obstruction?
Congenital duodenal obstruction (DO) has a well-known association with Down syndrome (DS) and other congenital malformations. Previously reported series on DO have not examined the influence of DS on associated congenital malformations and postoperative morbidity and mortality. We report on a retrospective study of all children born with DO over an 11-year period to investigate this. A total of 79 patients with DO were studied: group 1 consisted of 51 (64.6%) children without DS, and group 2 consisted of 28 (35.4%) children with DS. There was no significant difference in mean gestational age and birth weight between groups 1 and 2. A coexisting congenital malformation was found in 68% of patients. Gastrointestinal malformations were the most common in group 1 (71.1%), and cardiac malformations were the most common in group 2 (81.5%). The mean time to reach full intragastric feeds was 12 days, with no significant difference between the two groups ( p=0.383). Seven (8.9%) patients developed a postoperative complication, with no significant difference between both groups ( p=0.853). A total of 11 patients died: six (12%) in group 1 and five (28%) in group 2, with no significant difference between the groups ( p=0.454). DS does not influence the morbidity and mortality of DO but does carry a higher incidence of congenital cardiac abnormalities. Delayed mortality was a result of coexisting congenital cardiac and respiratory disease.
