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 evaluate the value of color ultrasound imaging in the measurement of visceral hemodynamics in patients with irritable bowel syndrome (IBS). Methods: 18 patients with irritable bowel syndrome and 20 normal control group were measured in the morning fasting and half an hour after meal mesenteric artery blood flow velocity and resistance. Results: There was no significant difference in blood flow velocity in patients with pre-meal irritable bowel syndrome compared with the normal control group, while the increase of blood flow in patients with IBS after a half-hour meal was significantly lower than that in the normal control group. Conclusions: Studies have shown that hemodynamic abnormalities are one of the causes of IBS.
