A 4-week-old term boy presented to the emergency department (ED) with recurrent bilious emesis. He had a history of neonatal abstinence syndrome, related to his mother’s use of Subutex (a form of suboxone that is considered safer during pregnancy) for her opioid addiction, and a Ladd procedure at Day 7 of life for intestinal malrotation with volvulus. He had been discharged from the hospital 4 days earlier, after recovery from surgery.
He had been doing well until the prior evening, when he developed “yellow-green” emesis and appeared to have intermittent abdominal pain. His parents said that he was refusing to take formula and he’d had frequent bilious emesis. They also noted he’d had 1 wet diaper in the past 12 hours and appeared “sleepier” than usual.
In the ED, the patient was listless, with thin and tremulous extremities. His fontanelle was flat, and his pupils were equal, round, and reactive. His mucous membranes were dry, skin was mottled, and capillary refill was delayed. His cardiopulmonary exam was normal. His abdomen was soft, mildly distended, and diffusely tender to palpation, with well-healing laparotomy scars. His reflexes were normal, with slightly increased tone. No bruising was noted.
An acute abdominal series, including an AP view chest x-ray (FIGURE 1), was obtained to rule out recurrent volvulus, free air, or small bowel obstruction.
