Abstract:
Objective To evaluate intraoporative ultrasonography (IOUS) of liver tumors. Methods In this study, 45 patients with liver tumors were examined by the IOUS(Logiq 500 scanner with a dedicated 5 ～ 7.5 MHz linear-array intraoperative transducer), and the results of IOUS were compared with those of preoperative ultrasonography (PHILIPS HDI 5000 scanner with a 3.5 ～ 5 MHz convex-array transducer) and computed tomography (CT). Results For tumors with a diameter ≥ 1 cm, the detection rate of IOUS was 100%, which was higher than that of preoperative ultrasonography and CT (100% vs 89.80% and 97.96%), though there was no statistical significance(xc2 = 3.372 ,P >0.05 and Fisher exact probability was 1.00) ; For tumors with a diameter < 1 cm, IOUS had a significantly higher detection rate than preoperative uhrasonography and CT(90.70% vs 62.79% and 74.42%, respectively,the former x2= 9.382, the latter x2 = 3.957, both P < 0.05) ;The total detection rate of IOUS was significantly higher than that of preoperative ultrasonography and CT (95.65% vs 77.17% and 86. 96%, respectively, the former x2 = 13.378, the latter x2 = 4.381, both P < 0.05). All the detected lesions underwent surgical resection or intratumoral injection of ethanol with the guidance of IOUS. Conclusions Compared with preoperative imaging examination, IOUS not only can enhance the detection rates of preoperatively overlooked lesions, but also can provide more valuable information to guide the surgical procedures.
