Abstract
AIM: To investigate the application of intraopera-tive ultrasound to surgery for liver neoplasms.
METHODS: Intraoperative ultrasound was used to scan 78 patients with liver neoplasms. The results of intraoperative ultrasound were compared with those of preoperative ultrasound and computed tomography (CT)/enhanced CT.
RESULTS: Of 65 patients suffering from liver cancer, intraoperative ultrasound determined all cases, whereas preoperative ultrasound and CT/enhanced CT missed 10 and 6 cases, respectively. For diagnostic accuracy of liver hemangioma, intraoperative ultrasound was better than preoperative ultrasound and CT/enhanced CT (92.31% vs 69.23% and 76.92%, respectively). For small-sized foci with diameters ≤ 1.0 cm, intraoperative ultrasound had a statistically significant better detection rate than preoperative ultrasound or CT/enhanced CT (90.48% vs 59.52% and 69.05%, respectively, both P < 0.05). Intraoperative ultrasound could also better ascertain lesions with diameters bigger. The detection rate was 96.36%, which was significantly higher than that of preoperative ultrasound (74 ......
