《急诊每日一题》谷氨酸转肽酶与总胆管结石2021年1月

Question 问题：

Spontaneous stone migration out of the common bile duct occurs in up to 20% of choledocholithiasis cases. GGT > 90 U/L is sensitive and specific for CBD stones. How long does the GGT normalize, even if the obstruction resolves immediately? 

大概20%总胆管胆囊结石患者中总胆管（CBD）结石会自动排出。谷氨酰转肽酶（GGT）> 90 U/L对CBD结石是敏感和特异的。即使梗阻立刻解除，GGT多长时间会恢复正常？

Answer 答案：

Elevation of GGT > 90 U/L is sensitive and specific for CBD stones, but it can subsequently take 2-4 weeks for these levels to normalize, even if the obstruction resolves immediately. 

GGT升高> 90 U/L对CBD结石是敏感和特异的，但即使在梗阻立刻解除后，GGT将需要2-4周恢复正常。
