Duodenal atresia and gastric antral web. A significant lesson to learn.

We report the case of a child who had a duodenal atresia and also a gastric-antral web. The two conditions are not known to be associated. The child had a duodenoduodenostomy for the duodenal atresia that had been diagnosed on a "double bubble" appearance at antenatal ultrasound scan. She eventually had a second laparotomy due to persistent gastric outlet obstruction, at which a pyloroplasty was performed and an antral web excised. The child remains well four months after discharge. This case has taught us several salutary lessons, which we consider relevant to share with colleagues.
