We evaluated the usefulness of ultrasonographic studies in the diagnosis of pleural adhesion before surgery in 120 patients with lung cancer. Sensitivity, specificity, and accuracy were 63%, 81%, and 72%, respectively, in the realtime diagnosis of pleural adhesion in 58 patients with ultrasonographic findings indicative of lung tumor; they were 31%, 80%, and 68%, respectively in 62 patients whose ultrasonographic findings were not indicative of lung tumor. Sensitivity was significantly higher in patients with ultrasonographic findings indicative of lung tumor than in those with negative findings (p>0.05). Our results indicate that ultrasonographic diagnosis of pleural adhesion is feasible: its specificity was about 80%, whether lung tumor was present or not.
