摘要
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 evaluate CT and ultrasonic imaging as a diagnostic means of acute intestinal obstruction. Methods Acute intestinal obstruction of 30 patients diagnosed by preoperative CT scanning and ultrasonic imaging was retrospectively viewed, compaired with intraoperative and pathologic findings. Results The overall accuracy of CT for detection of obstruction was 86.7% (26/30),CT and ultrasonic imaging was 93.3% (28/30). Conclusion CT with ultrasonic imaging is of great advantages for senile patients especially having malignant tumors and for patients with intestinal intussuception. CT with ultrasonic imaging is found to be reliable for diagnosing ileolithiasis and abdominal abscess and mesentery vein thrombosis, but is less sensitive in cases of bowel torsion.
