“Placement of the Stoma Site. The stoma site on the abdominal wall should be placed away from the rib cage because, with the child’s growth, the distance between the two tends to become shorter. A gastric access device that is too close to the ribs will cause discomfort and interfere with care. Additionally, pivoting motion resulting from breathing and moving can lead to stoma enlargement and leakage. In small children, the linea alba tends to be broad and very thin and also should be avoided as an exit site. The stoma site on the stomach should be in the mid-body—away from the greater curvature, because the proximity to the transverse colon can lead to a gastrocolic fistula; away from the fundus, to allow for a possible future fundoplication; and away from the presumed site of the gastric pacemaker, near the splenic hilum. It is critical to avoid the antrum to prevent pyloric obstruction by the catheter tip and interference with gastric emptying. A stoma in this position is also more likely to leak. Placements that exert downward traction on the stomach, particularly along the greater curvature, can interfere with the angle of His at the esophagogastric junction and therefore should be avoided.” — Pediatric Surgery (Springer Surgery Atlas) by Prem Puri, Michael E.

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]."
