Intrapelvic prosthesis to prevent injury of the small intestine with high dosage pelvic irradiation

Abstract

The major complication to delivering tumoricidal dosages of radiation to the pelvis is radiation damage to the loops of the small intestine located within the radiation field. To exclude the small intestine from the pelvis after extensive pelvic surgical treatment, prosthetic materials are used. A transabdominal baffle made of prosthetic mesh separates pelvic and abdominal cavities. A Silastic implant, usually used in the reconstruction of the breast, is used in the pelvis to occupy space. In so doing, all of the small intestine can be excluded from the pelvic cavity and dosages of radiation to 6,500 rads can be administered.
