[Interventional radiology of the digestive system].

The authors report on the use of interventional radiology modalities in the treatment of some gastrointestinal diseases (intussusception, stenosis, hemorrhage, etc). The results are compared with literature data relative to both interventional radiology and conventional therapeutic procedures. In our series, hydrostatic reduction of ileocolic intussusception was successful in 60% of cases. Transluminal dilatation with a balloon catheter was attempted in 108 patients with alimentary tract stenosis and was successful in 93. Hemorrhage and ischemia can be treated by means of transcatheter therapy (vasopressin, embolization) and percutaneous angioplasty. Percutaneous gastrostomy appears to be an effective alternative to surgical gastrostomy. Tapeworm infections can be cured by intraduodenal injection of "Gastrografin" (Schering). The success achieved in the different applications is such as to suggest a wider use of interventional radiology procedures, for they offer a more favorable cost/benefit ratio and often yield better results than conventional techniques.
