胃窗超声造影检查在胃癌术前分期中的局限性分析

Limitations of oral ultrasonic contrast agent for preoperative diagnosis of gastric carcinoma

目的分析胃窗超声造影检查在胃癌术前分期中的局限性,以提高其超声诊断的准确性。方法回顾性分析119例胃癌患者的120个癌结节行术前胃窗超声造影检查结果,以术后病理检查为金标准,对胃窗超声造影检查存在的误诊、漏诊原因进行分析。结果胃窗超声造影检查119例胃癌的120个癌结节中,漏诊4例,T分期误诊34例,误诊率为28.3%;N分期误诊60例,误诊率为50.4%;M分期漏诊4例,漏诊率为3.4%。结论准确地分析胃窗超声造影检查对胃癌术前分期的误诊、漏诊原因,并采取相应对策以提高超声诊断的准确性。

Objective To analyse the limitations of oral ultrasonic contrast agent for gastric carcinoma to improve the accuracy of diagnosis. Methods Medical records of 119 patients with gastric cancer were retrospectively reviewed to identify misdiagnoses and their contributing factors during preoperative ultrasound of 120 cancer nodules using oral ultrasonic contrast agent. Results Of the 120 nodules,four were not detected,34（28.3%）were misdiagnosed in the T stage,60（50.4%）were misdiagnosed in the N stage,and 4（3.4%）were not detected in the M stage. Conclusion Understanding the reasons for preoperative misdiagnosis of gastric carcinoma using oral ultrasonic contrast agent and adopt corresponding measures may improve diagnostic accuracy.
