Fewer than 20 patients born with situs inversus and duodenal atresia have been reported in the literature. We present a patient with this condition. A newborn baby presented shortly after birth with persistent bilious vomiting. An abdominal radiograph showed a right-sided stomach bubble and a second bubble on the left - Typical of duodenal atresia but with mirror image configuration. Laparotomy confirmed the diagnosis of situs inversus abdominalis, which was also demonstrated by contrast studies and ultrasound. Duodeno-duodenostomy was performed and the patient discharged on day 8 postoperatively. Situs inversus is associated with other congenital malformations including splenic malformations, left-sided liver and cardiac abnormalities; it is rarely associated with duodenal atresia. Duodenal obstruction in the presence of situs inversus has been described, including obstruction due to a web, stenosis, pre-duodenal portal vein and complete atresia. The patient presented in this paper had a duodenal web in the second part of the duodenum. Before undertaking surgery it is important to establish the presence of associated gastrointestinal and cardiac abnormalities.
