Over a period of 3 3/4 years, hydrostatic reduction of ileocolic intussusception was performed under sonographic guidance in 47 cases (a total of 41 consecutive patients). The enema consisted of a mixture of isotonic electrolyte solution and water-soluble contrast medium (9:1 ratio) and was given at a hydrostatic pressure of 80-100 cm water. Reduction was successful in 83% of cases (n = 39). Even initially remaining ileo-ileal intussusception could finally be reduced in two cases. No complications were observed. Since, in comparison with other conservative methods of reduction, the success rate was not substantially worse (versus that of pneumatic reduction) or was even higher (versus that of barium enema reduction), the method described can be recommended for wider use because of the substantial reduction in radiation exposure.
