多层螺旋CT诊断急腹症的临床效果分析

Clinical effect of multi-slice spiral CT in the diagnosis of acute abdomen

目的分析多层螺旋CT诊断急腹症的临床效果.方法选取2019年1月~2021年12月收治的127例急腹症患者为研究对象,对全部患者进行多层螺旋CT检查,观察平扫特征和动态增强扫描特征,采取MPR联合VRT、MIP、CPR等技术,对图像展开二维重建或三维重建,将诊断结果与临床或手术结果比较,分析多层螺旋CT诊断效果.结果127例患者中多层螺旋CT诊断准确例数为122例,总诊断准确率为96.06%.出血性疾病的多层螺旋CT诊断结果为17例为外伤致肝脾破裂、2例为肝癌致肝破裂、2例为肠系膜血肿、1例误诊、1例漏诊;梗阻性病变的诊断结果为肠梗阻和输尿管结石的诊断准确率均为100.00%;炎症性疾病的诊断结果为阑尾炎、胆道结石、急性胰腺炎、化脓性胆囊炎、消化道穿孔的诊断准确率分别为93.75%、100.00%、100.00%、100.00%和0.00%;穿孔性病变的诊断准确率为100.00%;缺血性病变的诊断准确率为80.00%.结论给予急腹症患者多层螺旋CT检查,能够显著提升诊断结果,为后续手术治疗方案制定提供依据.

Objective To analyze the clinical effects of multi-slice spiral CT in the diagnosis of acute abdomen.Methods 127 patients with acute abdomen in the hospital were treated from January 2019 to December 2021.All patients were confirmed by clinical or surgical examination.127 patients were examined by multi-slice spiral CT to observe their plain scanning characteristics and dynamic enhancement scanning characteristics.MPR technology was mainly used,combined with VRT,MIP,CPR and other technologies to carry out two-dimensional reconstruction or three-dimensional reconstruction of the image,The diagnostic results were compared with clinical or surgical results to analyze the diagnostic effect of multi-slice spiral CT.Results The accurate number of multilayer spiral CT diagnosis in 122 patients was 122,and the total diagnostic accuracy was 96.06%.The diagnostic results of multilayer spiral CT for hemorrhagic diseases were 17 traumatic patients with liver and spleen rupture,two liver cancer with liver rupture,two mesenteric hematoma,one misdiagnosis and one missed diagnosis.The diagnostic accuracy of obstructive lesions was 100.00%for both intestinal obstruction and ureteral stones.The diagnostic accuracy of inflammatory diseases of appendicitis,biliary stones,acute pancreatitis,purulent cholecystitis,and digestive tract perforation were 93.75%,100.00%,100.00%,100.00%,and 0.00%,respectively.The diagnostic accuracy of perforated lesions was 100.00%.The diagnostic accuracy of ischemic lesions was 80.00%.Conclusion Giving multi-slice spiral CT examination to patients with acute abdomen can significantly improve the diagnostic results,provide accurate and comprehensive information basis for the formulation of follow-up surgical treatment plan.
