All the women underwent para\u2010aortic lymphadenectomy, and nodes were assessed for metastasis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Thirty\u2010five women had pathological para\u2010aortic node metastasis. The sensitivity, specificity, and positive and negative predictive values of CT for the diagnosis of metastasis were 42.9, 96.1, 75.0 and 86.0%, respectively. These values were 60.0, 82.0, 47.7 and 88.2% for palpation, and 91.4, 69.5, 45.1 and 96.7% for intraoperative ultrasonography, respectively. If para\u2010aortic lymphadenectomy had been performed only when enlarged lymph nodes were detected on CT then the number performed would have been reduced from 163 to 20 (12.3%); however, node metastasis would have been missed in 20 out of 35 women. On the same basis, the number of lymphadenectomies performed would have been 44 (27.0%) and metastasis would have been missed in 14 women on palpation during surgery, and 71 lymphadenectomies (43.6%) would have been performed and metastasis would have been missed in three women on intraoperative ultrasonography.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Intraoperative ultrasonography is a highly sensitive tool with which to diagnose lymph node metastasis. Its high negative predictive value allows avoidance of unnecessary para\u2010aortic lymphadenectomy in women with ovarian and uterine corpus malignancy. Copyright \u00a9 2008 ISUOG.
