肠易激综合征患者肠系膜上动脉血流测定

MEASUREMENT OF THE SUPERIOR MESENTERIC ARTERIOUS BLOOD FLOW IN IRRITABLE BOWEL SYNDROME

目的 :评价彩色超声显像技术在测量肠易激综合征 (IBS)患者内脏血液动力学方面的价值。方法 :18例肠易激综合征患者和 2 0名正常对照组于早晨空腹及餐后半小时分别测量肠系膜上动脉血流速度及阻力。结果 :餐前肠易激综合征患者血流速度与正常对照组相比无显著性差异 ,而餐后半小时IBS患者血流增加量比正常对照组明显降低。结论 :研究表明血液动力学异常是引起 IBS发病原因之一。

Objective:To assess the role of Doppler ultrasound(US) in detecting changes in the splanchic hemodynamic veriables measured in patients with IBS and healthy subjects.Methods:Eighteen patients with IBS and twenty matched normal subjects were evaluated by means of Doppler US.The mean velocity of the Supperior mesenteric arterious blood flow and the resistance index(RI) were studied in the IBS patients and healthy controls between empty stomach and breakfast.Results:No significant difference were found between IBS and healthy controls before breakfast.After breakfast,the mean velocity of the blood flow was significantly lower in IBS than in healthy subjects.]Conclusion:This study shows that abnormal hemodynamic changes are one of the pathogeny causing IBS.
