What type of vomit is typically seen in children with intussusception?

In cases of intussusception, bile-stained vomit is often observed in children. This occurs because intussusception involves a portion of the intestine telescoping into another part, leading to an obstruction. As a result, the normal passage of intestinal contents is disrupted. When this obstruction occurs, digestive fluids, including bile, can back up and spill into the stomach, causing the vomit to take on a yellow-green appearance due to the presence of bile. This can be a significant indicator of bowel obstruction in the pediatric population and is critical for healthcare providers to recognize in order to prompt further evaluation and management.
