摘要
目的研究术中超声对肝脏肿瘤患者手术治疗的作用。方法应用５．０－ＭＨｚ特殊超声探头，对４９例患肝脏肿瘤或其他疾病可疑肝脏转移肿瘤的患者在开腹探查手术中进行术中超声检查。根据术前影像学检查（包括体外经皮超声、核磁共振成像和计算机断层扫描）及术中评定（包括肉眼观察、双手触诊及术中超声），对术前影像学检查与术中超声方法进行对比分析。结果术中超声、体外经皮超声、计算机断层扫描、核磁共振成像的敏感性分别为１００％（２３／２３）、７４％（１７／２３）、７４％（１４／１９）和７５％（６／８），特异性分别为１００％（２６／２６）、１００％（２６／２６）、９３％（１４／１５）和６７％（２／３）。７例（１４％）肝脏肿瘤患者经术中望诊、触诊均未发现病灶，仅靠术中超声检查才得以确定。结论术中超声是检查发现肝脏肿瘤的最敏感、特异的方法，它有助于肝脏肿瘤，尤其是肝脏隐匿性或微小病灶（＜２ｃｍ）的手术治疗。
Objective The purpose of this study was to evaluate the
impact of intraoperative ultrasound (IOUS) on the management of patients with neoplasms of the
liver. Methods Forty nine patients received operations for liver tumors were examined
intraoperatively with 5.0 MHz special ultrasound transducers during surgical exploration of the
abdomen.Preoperative imaging studies including percutaneous ultrasound ( n=49 ),magnetic
resonance imaging ( n=11 ) ,and computed tomography ( n=34 ) were taken to compare with
intraoperative ultrasonography for the evaluation. Results Sensitivity for detection of hepatic
neoplasms showed in intraoperative ultrasound ,percutaneous ultrasound,magnetic resonance
imaging and computed tomography as 100%(23/23),74%(17/23),74%(14/19),and 75%(6/8)
respectively.Specificity showed 100%(26/26),100%(26/26),93%(14/15),and 67(2/3) respectively.
Conclusions Intraoperative ultrasound was the most sensitive and specific method for
detection and surgery of liver neoplasms,especially the occult neoplasms and small size
lesion(<2 cm).# Corresponding author
