观察１５０例胆囊摘除、胆总管探查、Ｔ管引流者，将胆汁淀粉酶高于正常人血淀粉酶最大值作为胰胆液反流的依据、胆石症的胰胆液反流率明显高于非胆石组，泥沙石反流率高于胆固醇石反流，结石并发胰胆液反流与结石不并发胰胆液反流相比，前者胆总管扩张率明显增高；十二指肠反流是一种明显的胰胆液反流形式，并非无害。分析结石、阻道扩张与反流相关；胆囊摘除术前、后均可能发生反流，
Observe 150 cases of cholecystectomy, common bile duct exploration, T tube drainage, the bile amylase higher than normal human amylase maximum as the basis of pancreaticobiliary reflux, cholelithiasis was significantly higher than the rate of pancreaticobiliary reflux In the gallstone group, the rate of sediment reflux was higher than that of cholesterol stone, and the rate of common bile duct dilatation was significantly higher than that of common pancreaticobiliary reflux with stones without pancreaticoduodenectasis. Duodenal reflux was A clear form of pancreaticobiliary reflux, not harmless. Analysis of stones, barrier expansion and reflux related; gallbladder removal may occur before and after reflux,
