螺旋CT扫描对绞窄性肠梗阻的诊断价值

目的探讨多排螺旋CT扫描对绞窄性肠梗阻的诊断价值。方法收集我院2007年3月～2011年3月32例CT检查资料、手术病理结果齐全的绞窄性肠梗阻的CT影像,分析其对诊断绞窄性肠梗阻有价值的CT征象。结果诊断绞窄性肠梗阻有意义的CT征象有：肠壁增厚;肠系膜水肿、淤血;漩涡征及鸟嘴征;肠壁积气征;肠曲排列异常;肠腔积液密度增高;腹腔积液及血性腹水;腹腔游离气体;肠壁强化异常;肠系膜血管栓塞。结论螺旋CT扫描是术前诊断绞窄性肠梗阻的重要方法,对指导临床治疗具有重要价值。

The value of MDCT in diagnosing strangulated intestinal obstruction

Objective To investigate the value of multi-detector helical computed tomography（MDCT） in diagnosing strangulated intestinal obstruction.Methods We collected 32 patients suffered of strangulated intestinal obstruction in our hospital from March 2007 to March 2011,all the 32 cases were certified by surgery and histopathology,we analyzed the CT findings.Results The main CT findings in strangulated intestinal obstruction were： increased thickness of intestinal wall;mesentery edema and congestion;whirlpool sign and beak sign;intestinal wall pneumatosis;convolutions array abnormal;enteric cavity hydrops and the dense increased;seroperitoneum or bloody ascites;Peritoneal cavity free air;intestinal wall abnormal enhancement;mesentery embolism.Conclusion MDCT is a important way in diagnosing strangulated intestinal obstruction presurgery,and it is of great value in guiding clinical treatment.
