“…Although many intussusceptions are located in the transverse colon and although a mass is often visible on the supine radiograph, the movement of air into the ascending colon and cecum often outlines the intussusceptum when it is located in the proximal transverse colon or when it has not reached the transverse colon and is located within the ascending colon or cecum, thus expediting subsequent care (Fig 4). Unlike previous investigations that used KUB with upright views (3,8), our results indicate that the KUB plus leftside-down decubitus set is helpful in the diagnosis and care of patients suspected of having intussusception. Initial radiographs provide important information in patients presenting with abdominal findings and important management information in those with intussusception, such as the presence of high-grade small-bowel obstruction and the presence or absence of free air.…”
