Bilious Emesis in the Pediatric Emergency Department: Etiology and Outcome

The objective of this study was to describe the emergency department (ED) diagnoses in an unselected pediatric population with bilious emesis. In a multicenter, prospective, observational case series, a convenience sample of patients less than 21 years old with yellow or green emesis were assembled. Clinical review of each case was performed 2 weeks or longer after ED disposition. Two hundred twenty-seven patients with 230 ED encounters were enrolled. Of the 189 encounters (82.2%) with follow-up, 20 had surgical disease (10.6%; 95% C.I. 6.6%, 15.9%). There was no significant association between the color of the emesis and surgical disease (OR=2.3; 95% CI, 0.68, 8.6).
