摘　　要：目的探讨胃间质瘤诊断中采用彩色多普勒超声的价值。方法本研究选取2021年1月至2023年2月在唐山市人民医院经手术病理证实胃肠间质瘤的200例患者为研究对象,其中20例患者不符合纳入标准,28例患者不愿参与研究,9例患者中途退出,最终纳入143例患者作为研究对象,将其分为良性胃间质瘤组(n=87)、恶性胃间质瘤组(n=56)。两组均实施彩色多普勒超声检查,以病理学检查结果为金标准,分析彩色多普勒超声对胃间质瘤的诊断准确率,并比较两组间的肿块直径、形状、边界、内部回声、腹腔淋巴结肿大、肿块内收缩期峰值血流速度、血流的阻力指数及CDFI血流分级。结果彩色多普勒超声检查准确率与病理检查结果差异无统计学意义(P>0.05)。良性胃间质瘤超声特征中肿块直径≥5 cm、形状不规则、边界不清晰、内部回声不均匀、腹腔淋巴结肿大的发生率低于恶性胃间质瘤(P<0.001)。良性胃间质瘤的肿块内收缩期峰值血流速度和血流的阻力指数均小于恶性胃间质瘤患者,良性胃间质瘤肿块内CDFI血流分级低于恶性胃间质瘤患者(P<0.001)。结论彩色多普勒超声在诊断胃间质瘤中有较高价值,可为医师制定手术方案提供参考。Objective To investigate the value of color Doppler ultrasound in the diagnosis of gastric stromal tumor.Methods In this study,143 patients with surgically pathologically confirmed gastrointestinal stromal tumors in Tangshan People's Hospital from January 2021 to February 2023 were prospectively selected as the study objects,among which 20 patients did not meet the inclusion criteria,28 patients did not want to participate in the study,9 patients dropped out,and finally 143 patients were included as the study objects.They were divided into benign gastric stromal tumor group(n=87)and malignant gastric stromal tumor group(n=56).Color Doppler ultrasound was performed in both groups,and the diagnostic accuracy of color Doppler ultrasound for gastric stromal tumor was analyzed using pathological findings as the gold standard,and the mass diameter,shape,boundary,internal echo,abdominal lymph node enlargement,peak systolic blood flow velocity within the mass,resistance index of blood flow,and CDFI blood flow grading were compared between the two groups.Results There was no significant difference between the accuracy of color Doppler ultrasonography and pathological findings(P>0.05).The ultrasonic characteristics of benign gastric stromal tumor showed that mass diameter≥5 cm,irregular shape,ill-defined border,uneven internal echo and enlarged abdominal lymph nodes were less frequent than those of malignant gastric stromal tumor(P<0.001).The peak systolic blood flow velocity and resistance index of blood flow within the masses of benign gastric stromal tumor were smaller than those of malignant gastric stromal tumor,and the CDFI blood flow grading within the masses of benign gastric stromal tumor was lower than that of malignant gastric stromal tumor(P<0.001).Conclusion Color Doppler ultrasound has higher values in the diagnosis of gastric stromal tumor and can provide reference for physicians to develop surgical plans.
