In the case of suspected intussusception, what is the next best step in management?

In cases of suspected intussusception, performing an air contrast enema is considered the next best step in management because it serves both diagnostic and potentially therapeutic purposes. An air contrast enema involves introducing air into the bowel while simultaneously using contrast material that can enhance imaging. This method allows for the visualization of the intestine on X-rays, helping to confirm the diagnosis of intussusception by revealing the characteristic signs, such as the "target sign" or "doughnut sign" seen on imaging.

Additionally, during the procedure, the pressure from the air can sometimes reduce a non-complicated intussusception, offering a less invasive treatment option before considering surgical intervention. This is particularly beneficial in children, where intussusception is more common and can often be treated non-operatively if detected early.

The preferred choice focuses on less invasive methods before progressing to more invasive options, which is critical in managing pediatric patients effectively while minimizing risks associated with surgery. The other available options do not align with the immediate, effective approach typically taken in such situations.
