It is sometimes possible to perform the surgical treatment during a diagnostic examination. During laparoscopy, the surgeon removes the visible endometriosis sites as carefully and as completely as possible without harming the healthy tissues and the intact, neighbouring organs.

This precise, meticulous, microsurgical technique, which often makes use of laser technology, can only be performed by a skilful and well-trained gynaecologist.
