本研究应用彩色多普勒超声术前检测７４例胃窦肿瘤对肝的浸润及胃左动脉旁淋巴结肿大程度，并将对肝的浸润程度分为四型。检测结果与手术病理对照符合率为８３．８％，且有较高的敏感性和特异性。我们认为彩超判定胃窦肿瘤未浸润或仅粘连至肝，胃左动脉旁淋巴结未肿大或轻度肿大为手术适应症；彩超判定胃窦肿瘤轻度浸润肝，胃左动脉旁淋巴结中度肿大为手术相对适应症；彩超判定肿瘤明显浸润肝或左动脉旁淋巴结重度肿大为非手术适应症。
In this study, color doppler ultrasonography was used to detect the extent of hepatic infiltration and left gastric artery lymph node enlargement in 74 cases of gastric antrum tumors, and the degree of liver infiltration was divided into four types. The coincidence rate between the test results and the surgical pathology was 83.8%, and the sensitivity and specificity were high. We believe that color Doppler ultrasound imaging determines that the gastric antrum tumor is infiltrated or only adheres to the liver. The absence of enlarged or slightly enlarged gastric lymph nodes around the left gastric artery is an indication for surgery. Color Doppler ultrasonography identifies gastric antrum tumors with mild invasion of the liver, and the left gastric artery is adjacent to the lymph nodes. Swelling is a relative indication for surgery; Color Doppler ultrasound imaging indicates that the tumor is significantly infiltrated with the liver or the para-aortic lymph nodes are heavily swollen as non-surgical indications.
