CT对大肠癌并急性肠梗阻的诊断价值分析

Diagnostic value of CT for colorectal cancer with acute intestinal obstruction

目的探讨CT对大肠癌并发急性肠梗阻的诊断价值。方法回顾性分析2013年6月至2016年6月期间在本院就诊并同时行CT检查的150例大肠癌并发急性肠梗阻的患者临床资料,分析其对大肠癌和梗阻部位的诊断符合率、图像特点。结果150例大肠癌并急性肠梗阻患者中,经CT诊断为大肠癌患者共139例,诊断符合率为92.67%(139/150)。其中,乙状结肠癌、横结肠癌和直肠癌的诊断符合率均达到95%。术后结果显示,CT对梗阻部位诊断符合率为93.33%(140/150)。CT对肠壁增厚、腔内肿块、肠腔狭窄、增厚肠壁与正常肠壁交界处的"袖口征"或"肩征"征象可良好显像。结论 CT对大肠癌及并发急性肠梗阻的疾病与梗阻部位诊断符合率较高,对多种肠道结构改变显像良好。

Objective To study the diagnostic value of CT for colorectal cancer complicated with acute intestinal obstruction.Methods The clinical data of 150 colorectal cancer patients with acute intestinal obstruction who underwent CT examination in our hospital from June 2013 to June 2016 were retrospectively analyzed. The diagnostic agreement rate, image characteristics of colorectal cancer and obstructive sites were analyzed. Results Among the 150 cases of colorectal cancer with acute intestinal obstruction, 139 cases of colorectal cancer were diagnosed by CT, and the diagnostic agreement rate was 92.67%（139/150）. Among them the diagnostic agreement rate of sigmoid colon cancer, transverse colon cancer and rectal cancer was 95%. The postoperative findings showed that the diagnostic agreement rate of CT was 93.33%（140/150）. The ‘cuff sign＇ or ‘shoulder sign＇ at the junction of the intestinal wall and the normal intestinal wall can be well imaged by CT. Conclusion For patients with colorectal cancer with acute intestinal obstruction,CT has high diagnostic accuracy for obstructive sites of colorectal cancer with acute intestinal, and shows good imaging of various intestinal structure changes.
