[Use of endoscopy for sacral resection: a clinical case].

A case of clinical application of endoscopy in the course of surgery for sacral resection is discussed. Video-assisted frontal approach was used to ligate internal ileac vessels and to detach the fore end of tumor. Subsequently, the sacrum was removed via back access.

They developed within 3 months in 64% and their frequency was significantly higher in cases of repeat surgery, resection of proximal tibia with subsequent endoprosthetic replacement of defective knee joint as well as adjuvant polychemotherapy.
