|| <p>Okabayashi's radical extensive hysterectomy is one of the excellent operations for carcinoma of the cervix. In this study on the postoperative complications during the recent 5 years, we obtained the following results. 1. In the total of 861 cases studied, the primary mortality amounts to 1.2 per cent, the incidence of the uretero-vaginal fistula 2.7 per cent, the pelvic abscess 16.8 per cent, and the lymphocyst 23.3 per cent. 2. On comparing the results with our previous ones as well as those of
other investigators, it is found that satisfactory results have been obtained due to the advent of various antibiotics in recent years and also due to a marked
advance made in the technics of blood and fluid administration as well as anesthesia.
3. Since the various complications have not completely been overcome and they still pose an important problem, an effort should be made toward a better postoperative care in order to prevent the complications.</p>
