A comparative study on upfront common bile duct suturing and T-tube drainage after exploration of common bile duct stones / 中华普通外科杂志

ABSTRACT

Objective To evaluate upfront common bile duct suturing against T-tube drainage after exploration in the treatment of common bile duct stone.Methods 253 cases of extrahepatic bile duct stones treated at our department from 2008 June to 2012 January were randomly divided into primary suture group and T tube drainage group,by t test or analysis of variance independent sample comparison.Results All operations were successful.Postoperative bile leakage was observed in 2 patients in group A and 4 in group B respectively(P ＞ 0.05),there was no reoperations in the two groups.In group B retrograde biliary tract infection developed in one and was cured by biliary tract flush combined with antibiotics administration.The abdominal drainage was bile tainted fluid about 5-10 ml a day in bile leakage cases in both groups and healed itself in 3-4 days without fever,jaundice symptoms.There was no other severe complications such as pancreatitis.The postoperative biliary complication rate (P =0.802),operative time (P =0.137),intraoperative blood loss (P =0.069) and liver function recovery(ALT P =0.087,AST P =0.752,TBIL P =0.459,DBIL P =0.217,ALP P =0.576,GGT P =0.362) was not significantly different between the two groups.In group A postoperative flatus passing (P =0.037),postoperative fluid volume (P =0.008),postoperative hospital stay(P =0.015) were better than that in T-tube drainage group.At 3 to 12 months follow-up,no patients were found to have residual stones and biliary stricture in group A and group B.Conclusions With the definite indication and proficient surgical technology,primary suture of common bile duct after exploration is a safe and effective way after treatment of choledocholithiasis.
