The D-xylose excretion test appears to be a useful method of monitoring shunt patency after a portasystemic venous anastomsis for portal hypertension. A 5-hour urinary excretion greater than 6 g appears an acceptable indicator that the shunt is patent. A second criterion of patency is an increase of 4 g or more over the result of preoperative tests. If the excretion rate falls in the postoperative period or remains less than 4-2 g/5 h, the anastomosis may be assumed to be occluded.
D-木糖排泄试验似乎是监测门脉高压症门体静脉吻合术后分流道通畅情况的一种有用方法。5小时尿排泄量大于6克似乎是分流道通畅的一个可接受指标。通畅的第二个标准是比术前检查结果增加4克或更多。如果术后排泄率下降或持续低于4 - 2克/5小时，则可认为吻合口闭塞。
