She is concerned that her son has had intermittent periods of severe abdominal pain over the past several days that has been associated with emesis and currant jelly stool. Of note, the family lives in a rural part of the state, requiring a 2 hour drive to the nearest hospital. He currently appears to be in significant pain and has vomited twice in the past hour. On physical examination, a sausage-shaped mass is noted on palpation of the right upper quadrant of the abdomen. Ultrasound of the abdomen was consistent with a diagnosis of intussusception. An air-contrast barium enema was performed, which confirmed the diagnosis and also successfully reduced the intussusception. Which of the following is the next best step in the management of this patient?? A: Discharge to home with follow-up in 3 weeks in an outpatient pediatric gastroenterology clinic, B: Repeat barium enema q6 hrs to monitor for recurrence, C: Keep patient NPO and initiate work-up to identify lead-point, D: Admit to hospital for 24 hour observation for complications andor recurrence, E: Pursue urgent surgical reduction with resection of necrotic segments of bowel,  <response>: This is a clinical vignette about an 8-month-old boy with intussusception that was successfully reduced with an air-contrast barium enema. The key findings are that the child lives far from the hospital, had severe abdominal pain with vomiting and currant jelly stools, and a sausage-shaped mass was palpated on physical exam. Ultrasound and air-contrast enema confirmed the diagnosis of intussusception and successfully reduced it. The question asks for the next best step in management. Choice A is incorrect because the child should be observed for recurrence given the distance to care and severity of initial presentation. Choice B is incorrect because repeated enemas would expose the child to unnecessary radiation without clear benefit. Choice C is incorrect because lead point evaluation is not routinely needed after successful reduction. Choice D is correct because 24 hour admission for observation is recommended to monitor for recurrence, which can happen in up to 10 of cases. Choice E is incorrect because urgent surgery is not indicated after successful nonoperative reduction.D: Admit to hospital for 24 hour observation for complications andor recurrence
