Operative ultrasound examinations were performed using a 7.5-MHz transducer during nine operations for advanced gastric cancers and during six for early cancers. Normal stomach wall showed five layers that corresponded to histologic structures. Fourteen of 15 tumors, including nonpalpable early cancers, were localized with ultrasonography. In addition, both depth of penetration and lateral wall extension of the gastric cancers were precisely determined with this technique. Our preliminary results indicate that high-resolution operative ultrasonography may become a diagnostic aid during gastric cancer operations.
在9例进展期胃癌手术和6例早期胃癌手术过程中，使用7.5兆赫的探头进行术中超声检查。正常胃壁显示出与组织结构相对应的五层结构。包括不可触及的早期癌症在内的15个肿瘤中有14个通过超声检查得以定位。此外，利用该技术能够精确测定胃癌的浸润深度和侧壁延伸情况。我们的初步结果表明，高分辨率术中超声检查可能会成为胃癌手术中的一种诊断辅助手段。
