Agenesis of the gallbladder in duodenal atresia: two case reports

Agenesis of the gallbladder not associated with biliary atresia is quite rare. We wish to report two patients with gallbladder agenesis in association with duodenal atresia without biliary atresia. Liver biopsy in one patient was notable for an absence of both inflammation and ductal pathology. The unremarkable postoperative course included normal direct bilirubins and a HIDA scan that demonstrated very good bile excretion into the duodenum. Both children are doing quite well in follow-up.
