RESUMO
OBJECTIVE: To compare CO(2) and normal saline as distention media in office diagnostic hysteroscopy. METHODS: The outcome of more than 6000 office hysteroscopies was analyzed. We used carbon dioxide or saline as distension medium. Minor hysteroscopic techniques were performed when indicated. RESULTS: The major indication was abnormal uterine bleeding (45%). Satisfactory hysteroscopy was achieved in 92. 4% with CO(2) and in 98.3% with saline (P<0.05). Local anesthesia was used in 54 patients (1.5%) with CO(2) and in three patients (0. 1%) with saline (P<0.001). Four hundred and two women (16.3%) underwent hysteroscopic procedures under saline hysteroscopy. Endometrial polyps were removed in 281 patients, 75 IUDs were removed, 14 fibroids were extracted, uterine septa were excised in 11 cases and mild and moderate adhesions were transected in 21 patients. CONCLUSION: Saline office diagnostic hysteroscopy offers at least all the advantages of the CO(2) hysteroscopy, and gives the possibility to easily 'find and treat in situ' many of the lesions observed.
