USE OF EXPANDERS FOR PROTECTION OF VISCERA DURING IRRADIATION OF PELVIC TUMORS IN CHILDREN

The authors describe a new technique for radioprotection of pelvic vis cera by placement of expanders in the subperitoneal area before irradi ation of pelvic tumors. They use round shape sub-cutaneous expanders, the volume corresponding to children's weight. Seven patients were tre ated with excellent results, and minor complications: 2 rectitis due t o unsatisfactory displacement of rectum by the balloon. There were no complications related to the device itself. The prosthesis was easy to withdraw. This method seems a safe and effective technique in protect ing viscera.
