Duodenal atresia: not always a double bubble

Abstract: A newborn infant with a prenatal diagnosis of duodenal atresia and abdominal radiographs demonstrating air in distal bowel is presented. An upper gastrointestinal series revealed complete duodenal obstruction and duodenal atresia was confirmed at surgery. The significance of distal bowel gas and the embryological development of this unusual entity is discussed.

“…This finding is best visualized in cases of duodenal atresia or severe stenosis in which the proximal, left-sided bubble represents air and fluid in the stomach and the distal, right-sided bubble represents air in the dilated segment of the proximal duodenum [12]. Variations of this radiographic finding may be seen including the presence of distal bowel gas depending on the degree and location of obstruction [13]. Ultrasound can also be used in the antenatal period to raise suspicion of duodenal obstruction by demonstrating fluid filled structures in the upper abdomen with a paucity of fluid distally [12].…”

“…Oesophageal and duodenal atresia make up a major part of congenital lower and upper gastrointestinal system emergencies with an incidence of 1 in 2500–3000[ 9 ] and 1 in 10,000,[ 10 ] respectively, and jejunoileal atresia in the lower gastrointestinal system is the most common emergency cases with an incidence of 1in 5000. [ 11 ] In our study group, most also had oesophageal and small intestinal atresias, which made up approximately one-third of cases.…”

“…Unlike more distal small bowel (jejunal/ileal) atresia which is believed to be caused by an ischemic episode, DA is believed to result from the failure of the recanalization of the bowel lumen following the phase of epithelialization, proliferation, and subsequent vacuolization of the alimentary tract during embryonic development [ 6 8 ]. Between the 30th and 60th days of embryonic development, growth and differentiation of the alimentary tract are proceeding at great speed.…”
