摘要:目的:分析探讨多层螺旋CT扫描及其重建技术在诊断肠梗阻中的效果。方法:在2017年5月-2019年5月的时间范围内,选择我院90例疑似肠梗阻病例作为研究对象均用CT扫描,以手术病理证实结果作为金标准,分析CT诊断对肠梗阻的诊断结果。结果:CT诊断分析对肠梗阻的诊断灵敏度、特异度、准确性分别为97.56%(80/82)、62.50%(5/8)、94.44%(85/90),Kappa=0.715,手术病理诊断的结果与CT诊断结果之间具有良好一致性。结论:多层螺旋CT扫描及其重建技术对肠梗阻的诊断灵敏度、准确性都较高,可以清晰了解患者梗阻的位置、梗阻的病因以及梗阻的病情程度,值得临床推广。

Abstract: Objective: To analyze the effect of multi-slice spiral CT scan and its reconstruction technique in the diagnosis of intestinal obstruction. Methods: To select 90 suspected intestinal obstruction patients, as study subjects from 2017.5 to 2019.5, who were given CT scan, their intestinal obstruction diagnosis results were analyzed by CT scan in according with the surgical pathology confirmation results as the gold standard. Results: It showed that, diagnostic sensitivity, specificity and accuracy by CT analysis of intestinal obstruction were 97.56%(80/82), 62.50%(5/8), 94.44%(85/90), Kappa=0.715, respectively. The results of surgical pathology diagnosis and CT diagnosis are consistent. Conclusion: Multi-slice spiral CT scan and its reconstruction technique features higher sensitive and accurate in the diagnosis of intestinal obstruction. It can clearly locate the patients obstruction position, cause and the obstruction degree, it is worth of promotion.

由任何原由致肠内通过障碍都统称为肠梗阻[1],属于一种常见的外科急腹症,临床症状为腹痛、呕吐、停止排便以及腹胀等[2]。肠梗阻由于病因复杂、患者发病急且病情变化快,有较高致死率[3]。所以对肠梗阻进行精准的早期诊断,可以帮助对患者采取及时有效的治疗。临床上,医生需明确疑似肠梗阻患者的梗阻具体位置以及病变原因与程度。常用肠梗阻检测方式为钡剂造影和腹部平片[4],两者均有检测上的局限性,CT检查是近年来临床反响不错的肠梗阻检测方式,其对肠梗阻的诊断灵敏度、准确性都较高。本院就多层螺旋CT扫描及其重建技术对肠梗阻的诊断效果进行研究分析,做出如下报告。
