经腹超声检查对炎症性肠病诊断及活动性评价的分析

Analysis on diagnosis and activity evaluation of inflammatory bowel disease by transabdominal ultrasonography

目的探讨经腹超声检查对炎症性肠病诊断及活动性评价的情况。方法分析汕尾市第二人民医院2013年9月-2015年2月48例炎症性肠病患者的临床资料,溃疡性结肠炎25例,分为活动组15例和缓解组10例;克罗恩病23例,分为活动组13例和缓解组10例。选取同期健康体检者50例作为对照组。观察三组患者肠壁厚度、肠壁内血流分级、肠壁内动脉阻力指数情况。结果溃疡性结肠炎活动组[（4.4±0.5）mm]、溃疡性结肠炎缓解组[（3.5±0.6）mm]的肠壁厚度均高于对照组[（2.7±0.4）mm];克罗恩病活动组[（6.4±1.5）mm]、克罗恩病缓解组[（3.8±0.8）mm]的肠壁厚度均高于对照组[（2.7±0.4）mm],差异均有统计学意义（P〈0.05）。溃疡性结肠炎活动组（0.63±0.04）、溃疡性结肠炎缓解组（0.68±0.03）的肠壁内动脉阻力指数均明显低于对照组（0.71±0.05）;克罗恩病活动组（0.62±0.05）、克罗恩病缓解组（0.65±0.04）的肠壁内动脉阻力指数均明显低于对照组（0.71±0.05）,差异均有统计学意义（P〈0.05）。三组肠壁内血流信号分布情况比较,差异均有统计学意义（P〈0.05）。结论经腹超声检查对炎症性肠病诊断及活动性评价具有重要的意义,值得临床推广应用。

Objective To explore the diagnosis and activity evaluation of inflammatory bowel disease by transabdominal ultrasonography. Methods The clinical data of 48 patients with inflammatory bowel disease treated in our hospital from September 2013 to February 2015 were analyzed.25 of them were ulcerative colitis（UC）,which were divided into the active group（n=15） and the relieved group（n=10）.Another 23 patients were with Crohn′s disease,which were also divided into the active group（n=13） and the relieved group（n=10）.50 healthy volunteers were selected as the control group.The thickness of intestinal wall,grade of blood flow in intestinal wall,and artery resistance index in intestinal wall of the three groups were observed. Results The thickness of intestinal wall of patients in the UC active group [（4.4±0.5） mm],the UC relieved group [（3.5±0.6） mm] was higher than that in the control group [（2.7±0.4） mm].The thickness of intestinal wall of patients in the Crohn′s disease active group [（6.4±1.5） mm],the Crohn′s disease relieved group [（3.8±0.8）mm] was higher than that in the control group [（2.7±0.4） mm].The rates of blood flow in intestinal wall had significantly differences between different grade in the three groups.The artery resistance index in intestinal wall in the UC active group（0.63±0.04）,in the UC relieved group（0.68±0.03） was significantly lower than that in the control group（0.71±0.05）.The artery resistance index in intestinal wall in the Crohn′s disease active group（0.62±0.05）,in the Crohn′s disease relieved group（0.65±0.04） was significantly lower that in the control group（0.71±0.05）,with significantly differences（P〈0.05）. Conclusion Transabdominal ultrasonography has great significance in diagnosis and activity evaluation of inflammatory bowel disease,which is worthy to be promoted.
