This document discusses intussusception, which is the invagination of one part of the intestine into another. It is most common in infants and toddlers, with 90% occurring in children within 3 years of age. There are different types including general, specific, anatomic. Treatment involves admission, hydration, antibiotics, and intervention such as intussusception reduction through open surgery, USG guided hydrostatic reduction, or C-arm guided pneumatic reduction. C-arm guided pneumatic reduction has benefits such as being quick, ensuring procedure completion under anesthesia with less risk of complications compared to other methods. Exploration surgery may be needed if reduction fails or there are issues like bowel gangrene or perforation.
