目的 探讨螺旋CT、补充B型超声显像在急性肠梗阻病因诊断中的作用。方法 对 3 0例急性肠梗阻患者术前的螺旋CT及B超显像检查资料进行综合分析。结果 螺旋CT对急性肠梗阻的病因诊断符合率为 86.7% ( 2 6/ 3 0 ) ,加用B超显像弥补CT动态观察不足后 ,诊断正确率提高至 93 .3 % ( 2 8/ 3 0 ) ;对耐受性差的中、老年患者优势明显 ,尤其对肿瘤引起的肠梗阻、肠套叠等正确率高 ;对肠间脓肿、肠结石症所致肠梗阻可提出正确诊断 ,对肠系膜静脉栓塞诊断符合率高且无创伤 ,但对肠扭转引起的肠梗阻正确性低。结论 螺旋CT、补充B超显像对急性肠梗阻的病因诊断具有特殊作用。
Objective To investigate the role of spiral CT in the diagnosis of acute intestinal obstruction. Methods A total of 30 cases of acute intestinal obstruction patients with preoperative spiral CT and B ultrasound imaging data were analyzed. Results The coincidence rate of spiral CT in etiological diagnosis of acute intestinal obstruction was 86.7% (26/30). After using B-scan imaging to make up for the lack of CT dynamic observation, the correct rate of diagnosis was 93.3% (28/33) 0); poor tolerance of middle-aged and elderly patients have obvious advantages, especially for tumor-induced intestinal obstruction, intussusception and other high correct rate; for intestinal abscess, intestinal stones cause intestinal obstruction can be the correct diagnosis of mesenteric Venous embolism with high diagnostic accuracy and no trauma, but intestinal obstruction caused by intestinal correctness is low. Conclusion Spiral CT and B-ultrasound imaging have a special role in the diagnosis of acute intestinal obstruction.
