12只犬共造成54段有血循环障碍的小肠袢,分别为动脉阻断型、静脉阻断型、动静脉阻断型和绞窄型。在解除梗阻恢复血流后15分钟,分别以临床判断法、多普勒法、荧光素法和24小时后2次手术探查法预测绞窄肠段生活力。结果表明,荧光素法的判断正确率明显高于临床判断法和多普勒法,与2次手术探查法相近。由于荧光素法具有快速简便、准确性高、无损害性、易于施行等优点,可望成为一种较实用的术中预测绞窄肠段生活力的辅助诊断方法。
Twelve dogs had a total of 54 small intestinal fistulas with blood circulation disorders, namely arterial blockage, venous blockade, arteriovenous blockage, and strangulation. Fifteen minutes after the release of obstruction and blood flow, the viability of the strangulated intestine was predicted by clinical judgment, Doppler, fluorescein, and two surgical explorations 24 hours later. The results showed that the accuracy of the fluorescein method was significantly higher than that of the clinical judgment method and the Doppler method, and it was similar to the two surgical exploration methods. As the fluorescein method has the advantages of rapid and simple, high accuracy, non-damaging, easy to implement, etc., it is expected to become a more practical method of intraoperative prediction of viability of the strangulated intestine.
