The current nonoperative management of ileocolic intussusception includes hydrostatic and pneumatic reduction, both performed under fluoroscopic monitoring. Recently, a new technique — ultrasoundguided reduction — replaced the conventional approach in our institution. Over a 20-month period, 46 intussusceptions were diagnosed sonographically in 40 patients. In all cases, reduction was attempted under ultrasound guidance by means of a normal saline enema. In 42 cases (91) reduction was successful and only four patients had to be operated (two resections, two manual reductions). Complications did not occur. this technique permits distinct visualization of the entire process, providing a clear and detailed echogram of the fluid-filled large and small intestine. We established the following definite criteria of reduction: disappearance of the target, demonstration of the ileocecal valve, visualization of the fluid reflux, and fluid filling of small bowel loops. The presented technique for the reduction of intussusception without radiation exposure is reliable and safe, and appears to be one of the most promising methods for the nonoperative treatment of ileocolic intussuscept
