Exchange of an occluded nasojejunal tube facilitated by angioplasty balloon-induced rupture.

We describe a method of exchanging a blocked nasojejunal (NJ) tube involving the use of a percutaneous transluminal angioplasty balloon to rupture the tube, followed by insertion of a guidewire through this rupture to create a guide for subsequent placement of a modified NJ tube. We used this technique in a child with a critical need for an NJ tube, in whom routine guidewire exchange was not feasible because of tube obstruction as well as the patient's anatomic abnormalities. This technique might also be useful for other patients in whom standard techniques are ineffective.
