探讨低张气充盈法多层螺旋CT增强扫描(EMSCT-LTGF)在胃部病变内镜治疗术前评估的价值。

回顾性分析2018年1月至2019年4月临汾市中心医院收治具有完整资料的胃部病变60例，均经手术获得病理结果，包括神经内分泌瘤、息肉、腺瘤、平滑肌瘤、胃肠道间质瘤、脂肪瘤、异位胰腺、外压、胃壁脓肿、胃溃疡等，术前行EMSCT-LTGF评估，并与病理结果对照。

与病理结果进行对照后发现，EMSCT-LTGF与胃镜在检出病变溃疡方面的比较差异无统计学意义。EMSCT-LTGF判断病变深度与病理结果比较差异无统计学意义。

EMSCT-LTGF在评估胃部病变溃疡、深度、形态、直径、密度、血供、淋巴结及远处脏器转移、邻近结构有无侵犯等方面有较高价值，能够为胃部病变内镜治疗术前提供准确的依据。

To investigate the value of enhanced multi-slice spiral CT with low tension gas filling(EMSCT-LTGF)in preoperative evaluation of endoscopic therapy for gastric lesions.

A retrospective analysis was performed on 60 cases of gastric lesions treated in Linfen Central Hospital from January 2018 to April 2019 with complete data, all of which obtained pathological results by surgery, including neuroendocrine tumor, polyp, adenoma, leiomyoma, gastrointestinal stromal tumor, lipoma, ectopic pancreas, external pressure, gastric wall abscess, gastric ulcer, etc.The lesions were evaluated by EMSCT-LTGF preoperatively and compared with pathological results.

When compared with pathological findings, there was no significant difference between EMSCT-LTGF and gastroscopy in the detection of lesion ulcer.There was no significant difference between EMSCT-LTGF and pathological results in judging the depth of lesion.

EMSCT-LTGF is of high value in the evaluation of gastric ulcer, depth, shape, diameter, density, blood supply, lymph node and distant organ metastasis and invasion of adjacent structures, which can provide accurate basis for endoscopic treatment of gastric lesions before operation.
