Does pyloric stenosis cause yellow bile in the vomit?

No: Bile is green. Babies with pyloric stenosis also have hyperbilirubinemia and this can cause the gastric secretions to take on a yellow hue.

Not bile: Technically, there can be no bile in the emesis of a patient with pyloric stenosis. The pylorus is the muscular valve that controls exit of contents from the stomach. When the pylorus is stenotic, it is virtually closed, and the patient vomits out all gastric contents. Bile enters the GI tract in the duodenum downstream from the pylorus and stomach, so it can't be in the emesis of such a patient.
