This quote from "The SAGES Manual of Pediatric Minimally Invasive Surgery" by Danielle S. Walsh, Todd A. Ponsky, Nicholas E. Bruns -
"Review of the KID data found a 1.67 odds ratio of small bowel resection with operative intervention delayed until hospital day 3–14, and no difference in small bowel resection between operating on day 1 versus day 2. It is recommended that stable patients without concerning signs of perforation, strangulation, or peritonitis can be safely managed conservatively for 48 h in children over 2 years and 24–48 h in children less than 2 years of age [18]. It is crucial that these patients are closely observed for signs of deterioration in either their physiology or abdominal exam and receive prompt operative management at recognition of these changes. If patients do not improve over the observation period, it is recommended that they also receive operative intervention [18]."
