Abstract:
Objective To evaluate the accuracy of intraoperative ultrasonography (IUS) in judging the relationship between central bronchogenic carcinoma and pulmonary vessels and in predicting the resectability of the tumor. Methods Intraoperative ultrasonograpy(IUS) and preoperative CT scanning were performed in 30 patients of central bronchogenic carcinoma. The relationship between vessel and tumor as assessed by IUS and preoperative CT were quantified and scored with a ranging from 0-4 respectively, and then the resectability of the tumor and optimal surgical method were predicted according to the scores. Results The accuracy of CT and IUS to determine tumor-vessel relationship was 72.3%(141/195) and 81.0%(171/211), respectively (P=0.037). The sensitivity of CT and IUS in predicting the resectability of tumor was 91.3%(21/23) and 95.6%(22/23), respectively, the specificity was 28.6%(2/7) and 57.1%(4/7), respectively, and the accuracy was 76.7%(23/30) and 86.7%(26/30), respectively. The accuracy of CT and IUS in predicting surgical strategy was 53.3%(16/30) and 63.3%(19/30), respectively(P=0.432). Conclusion IUS is a useful method in predicting the resectability of centrally located bronchogenic carcinoma.
