摘要
目的评价四维超声成像在诊断胃癌术前分期中的临床价值。方法对46例胃镜检查疑诊胃癌患者进行四维超声检查,然后基于统计分析对比分析两种诊断结果。结果46例胃镜检查疑诊胃癌患者中病理确诊41例,符合率89.1%(41/46);四维超声诊断胃癌37例,符合率80.4%(37/46),经卡方检验对两种检查结果进行统计分析,结果两者在胃癌诊断准确率上无明显的差异。另外,四维超声在胃癌术前分期中与病理诊断分期对比,准确率78.4%(29/37)。其中,早期胃癌4例,四维超声诊断准确率为50%(2/4),进展期胃癌33例,超声诊断准确率为81.8%(27/33)。结论进展期胃癌四维超声和胃镜诊断的准确率较高,但四维超声检查无创、可重复,且在胃癌术前分期诊断中有独特的优势。
Objective To analysis the clinical value of four-dimensional （4D） ultrasound used for preoperative staging of gas- tric cancer. Methods The 4D ultrasound inspection was done for 46 patients with suspected diagnosis （detected by gastroscoppe） of gastric cancer. Then ii^e statisiiccontrastive analysis was done between the diagnosis results using 4D ultrasound and gastro- scope. Results 41gastric cancer patients confirmed with pathologically, among the 46 patients detected with gastric cancer by gastroscope. Thus the coincidence rate of gastroscope diagnosis was 89.1%（41/46）. The coincidence rate of ultrasound diagnosis was 80.4%, where 37 confirmed with gastric cancer using 4D ultrasound among the 46 patients （with suspected gastric cancer） . Based on the chi-square test, there w^is no significant difference between the accuracy rates diagnosed by 4D ultrasound and gas- troscope. Moreover, by means of 4D ultrasound, the accurate rates in preoperative stage and early diagnosis were 78.4%（29/37） and 50%（2/4）, respectively. There were 4 patients with early gastric cancer detected with 4D ultrasound, while there were 2 pa- tients confirmed with early gastric cancer. And then, in the advanced stage of gastric cancer, the accurate rate of 4D ultrasound is 81.8%（27/33）. Conclusion There are high detected accurate rates in the advanced stage of gastric cancer, by means of 4D ultra- sound and gastroscope. 4D ultrasound is noninvasive and repeatable, and there is unique advantage in the preoperative staging of gastric cancer （owing to a wealth of diagnosis information）.
