Conisation as an important point in the diagnosis and treatment of pre-invasive neoplasy

110 cases of conisation carried out in the Obstetric and Gynecological Clinic of the University of Padua between 1.1.74 and 31.12.82 have been considered. The operations were always performed on completion of diagnostic assertions comprising colpocytology, colposcopy and biopsy, this last undertaken upon indications from both colposcopic and colpo-cytological examinations. The comparison of the histological sample with the serial on the cone, with the cytological, colposcopical and bioptic ones, correspond in the importance of the lesion in almost 90% of cases. The reliability of the diagnosis by the three methods associated and then integrated by the conisation therefore approaches 100%. Prophylaxis carried out in this way allows a personalisation in the operation which, though respecting radicality, must be as non-demolitary as possible.
