胃癌浆膜面不同CT表现类型对判断浆膜有无侵犯的价值探讨

摘要

Objective To investigate the different types of Gastric serosa CT,and judge whether the violations of serous value and clinical significance. Methods Retrospective analysis of our hospital in July 2014~ December 2015 which is treated 75 cases during the clinical data of patients with advanced stomach cancer, all patients were treated with spiral CT scanning, according to the pathologically confirmed results to analyzed,.Nest,explore the gastric serosa violations and pathological findings different.Results All patients were confirmed by pathology detected 47 cases of violations of serous, 28 cases of serous were not violated; including 18 cases of adjacent structures by invasion. The CT detected violated serosa sensitivity was 89.36%(42/47), the specificity of case was 67.86%(19/28), the accuracy was 80.14%(61/75).Conclusion When the gastric cancer patients was suffered with serous violations, According to the CT, the patients of surface was roughness, the cancer adjacent of fat space was blur, the cancer of nodular was protrusion. CT detection of serous surface roughness sensitivity is higher, but relatively with low specificity, try to observed in connection with various signs of CT and comprehensive diagnosis in clinical diagnosis.%目的：研究探讨胃癌浆膜面不同CT表现类型以及据此判断浆膜有无侵犯的价值及临床意义。方法回顾分析2014年7月～2015年12月期间收治的75例进展期胃癌患者临床资料，全部患者均采用螺旋CT扫描，并与手术病理证实结果进行对比分析，探讨胃癌浆膜面侵犯与病理结果差异。结果全部患者均通过病理学检测证实47例浆膜遭受侵犯，28例浆膜未受侵犯；其中包括18例临近组织结构受到侵润。CT检测胃癌浆膜侵犯敏感度89.36%（42/47），特异性67.86%（19/28），准确率80.14%（61/75）。结论进展期胃癌患者浆膜遭受侵犯之后，其CT主要表现为浆膜面粗糙、癌肿邻近脂肪间隙模糊、癌肿结节状外突。CT检测对浆膜表面粗糙的敏感度较高，不过特异性相对较低，在临床诊断中尽量结合各种CT征象进行综合观察诊断。
