Abstract

Congenital duodenal obstruction (DO) is a frequent cause of congenital intestinal obstruction in the newborn, occurring in 1 per 5,000-10,000 live births, and affecting boys more commonly than girls. DO is the result of either intrinsic or extrinsic lesions. Figure 39.1 shows the various types of DO. Intrinsic DO may be caused by duodenal atresia, stenosis, diaphragm, perforated diaphragm, or a wind-sock web. The wind-sock web is a duodenal membrane that balloons distally as a result of peristalsis from above. Extrinsic DO may be caused by annular pancreas, mal-rotation, or preduodenal portal vein. Although the annular pancreas forms a constricting ring around the second part of the duodenum, it is not believed to be the cause of DO and there is usually an associated atresia or stenosis in patients with an annular pancreas (Fig. 39.2).
