摘　　要：目的探讨灰阶超声结合能量多普勒对炎症性肠病的诊断价值。方法选择2012年5月-2014年4月医院克罗恩病患者50例为克罗恩病组,溃疡性结肠炎患者50例为溃疡性结肠炎组,健康者50例为对照组;二维灰阶超声、能量多普勒、脉冲多普勒分别测量炎症性肠病的肠壁厚度、血流分级、动脉阻力指数。结果超声诊断克罗恩病的准确率为92%,诊断溃疡性结肠炎的准确率为84%;克罗恩病及溃疡性结肠炎活动期和缓解期患者肠壁内血流分级比较差异有统计学意义(P<0.05),克罗恩病和溃疡性结肠炎活动期肠壁内血流分级和对照组比较差异均有统计学意义(P<0.05),克罗恩病缓解期肠壁内血流分级和对照组比较差异有统计学意义(P<0.05);克罗恩病及溃疡性结肠炎活动期、缓解期的肠壁内动脉阻力指数均高于对照组(P<0.05);克罗恩病及溃疡性结肠炎活动期、缓解期的肠壁厚度均高于对照组(P<0.05)。结论灰阶超声结合能量多普勒对炎症性肠病的诊断准确率高,并能评估炎症性肠病的活动性。OBJECTIVE To explore the value of gray-scale ultrasound combined with power Doppler in diagnosis of inflammatory bowel diseases）METHODS A total of 50 patients with Crohn＇s disease who were treated in the hos- pital from May 2012 to Apr 2014 were assigned as the Crohn＇s disease group, 50 patients with ulcerative colitis were chosen as the ulcerative colitis group, and 50 healthy people were set as the control group. The bowel wall thickness, blood flow grade, and artery resistance index of inflammatory bowel disease were measured by respec- tively using gray-scale ultrasound, power Doppler, and pulse Doppler. RESULTS The accuracy of ultrasound was 92% in diagnosis of Crohn＇s disease, 84 % in diagnosis of ulcerative colitis. There was significant difference in the blood flow grade inside the bowel wall between the patients with Crohnrs disease and ulcerative colitis in active stage and the patients with Crohn＇s disease and ulcerative colitis in remission stage （P〈0.05）; there was signifi- cant difference in the blood flow grade inside bowel wall between the patients with Crohn＇s disease and ulcerative colitis in active stage and the control group （P〈0.05）. There was significant difference in the blood flow grade in- side bowel wall between the patients with Crohn＇s disease in remission Stage and the control group （P〈0.05）, The artery resistance index inside the bowel wall of the patients with Crohn＇s disease and ulcerative colitis in active stage, remission stage was higher than that of the control group （P〈0.05）. The bowel wall thickness of the pa- tients with Crohnrs disease and ulcerative colitis in active stage, remission stage was higher than of the control group （P〈O. 05）. CONCLUSION The accuracy of the gray-scale ultrasound combined with power Doppler is high in diagnosis of the inflammatory bowel diseases and can assess the activity of the inflammatory bowel diseases.
