BACKGROUND
This study was designed to perform a comparative analysis between endoscopic ultrasonography (EUS) and double contrast-enhanced ultrasonography (DCEUS) for the preoperative diagnosis of gastric stromal tumors (GSTs).
METHODS
A retrospective study was conducted involving 139 patients with histologically confirmed GSTs. All patients preoperatively underwent DCEUS and EUS. The pathology reports were treated as the baseline and were retrospectively compared with the findings of EUS and DCEUS.
RESULTS
Of the 139 lesions, 120 and 113 were correctly identified by DCEUS and EUS, respectively, with an accuracy of 86.3% and 81.3%. The results revealed an insignificant difference between these two methods (p = 0.189).
CONCLUSIONS
DCEUS can display not only the locations, sizes, shapes, borders, internal echoes, but also show the blood perfusion patterns of GSTs. It is a highly accurate, noninvasive, and convenient method to be used at the pre-treatment stage.
背景
本研究旨在对内镜超声（EUS）和双对比增强超声（DCEUS）在胃间质瘤（GSTs）术前诊断中的应用进行对比分析。
方法
对 139 例经组织学证实的 GSTs 患者进行回顾性研究。所有患者均行 DCEUS 和 EUS 检查。病理报告作为基线，并与 EUS 和 DCEUS 的结果进行回顾性比较。
结果
在 139 个病灶中，DCEUS 和 EUS 分别正确识别了 120 个和 113 个病灶，准确率分别为 86.3%和 81.3%。两种方法的结果无显著性差异（p=0.189）。
结论
DCEUS 不仅可以显示 GSTs 的位置、大小、形状、边界、内部回声，还可以显示其血流灌注模式。它是一种在治疗前阶段高度准确、无创、方便的方法。
