Q

Algorithm for bilious emesis?

A

If baby is vomiting bile, get a babygram and look at the bowel. If there are multiple air fluid levels, then baby has intestinal atresia caused usually by maternal cocaine use causing intrauterine infarctions. Treat with surgery. If baby just has a double bubble sign then baby has duodenal atresia or annular pancreas. Treat with surgery. If baby has double bubble sign AND normal air in bowel then malrotation has occured. Get an enema to reveal and an upper GI series if negative to confirm. If either or positive, it’s malrotation and emergency surgery must be done. If negative, urgent surgery.
