Omentum flap as a spacer before carbon ion radiotherapy for gynecological recurrences. A technical note

Abstract

Re-irradiation of pelvic recurrent gynecological cancer is a challenge due to the proximity of high-radiation-sensitive organs, such as the bowel and the urinary tract. Hadrontherapy for re-irradiation emerges as a safe and effective treatment with a mild rate of morbidity of surrounding normal tissue. To improve the dose to the tumor, a prophylactic displacement of organs at risk is needed, and a multidisciplinary approach is recommended. In this technical note, we report a surgical technique of omentum spacer placement for patients enrolled for carbon ion radiotherapy as re-irradiation for recurrent gynecological tumors.
