Laparoscopic surgery occupies an increasingly important place in the d
iagnosis and staging of gynaecological cancers. It allows repeated com
plete investigation of the abdomen and retroperitoneum : macroscopic e
xamination of the peritoneum, cytology, biopsies, infracolonic omentec
tomy, appendicectomy, pelvic and para-aortic lymphadenectomy, without
interfering with therapeutic procedures (simple or radical hysterectom
y) which can be associated. In cancers of the endometrium, it is part
of a surgical strategy associating vaginal hysterectomy. In ovarian ca
ncers, it is essentially applied to restaging of insufficiently explor
ed apparent stage I tumours. In operable cervical cancer, it guides th
e therapeutic protocol and surgical indication by allowing interiliac
lymphadenectomy. In advanced cervical cancers, it is used to detect pa
ra-aortic lymph nodes.
