Ileocolic intussusception: hydrostatic reduction in the presence of the dissection sign.
Hydrostatic reduction of an ileocolic intussusception has not been reported when barium dissects around the intussusceptum as opposed to pushing it retrograde. Consequently, this development is considered an indication to discontinue hydrostatic reduction. We have studied a baby in whom draining the colon caused a seemingly irreversible dissection of barium to disappear so that hydrostatic reduction of the intussusception was easily accomplished when the colon was refilled with barium.
