RESUMO
Objective To investigate the related risk factors caused the retained common bile duct (CBD)stones after laparoscopic cholecystectomy,to provide the evidence for preventing from retained common bile duct stones of laparoscopic cholecystectomy.Methods Selected 654 cases of laparoscopic cholecystectomy patients as the objects whom hospitalized in Beijing Chuiyongliu Hospital from January 2002 to June 2013.All cases were divided into the group of retained CBD stones (27cases) and the group of non-retained CBD stones (627 cases).Collected the potentially relevant factors of two groups with the retained CBD stones,including medical history of jaundice and pancreatitis,common bile duct internal diameter (B Ultrasound) ≥ 8 mm,acute cholecystitis,emergency surgery,gallbladder removal order,calot triangle adhesion,sludge calculus,stones neck incarcerated,fulltype stones,cystic duct thickening,cystic duct reserved≥ 1 cm,the minimum diameter stones ≤5 mm,the number of gallbladder stones ≥ 5,partial cholecystectomy,purulent bile.Statistics analyses was proceeded using the IBM SPSS 20.0.Result Through dichotomy logistic regression analysis to the univariate analysis results with statistical significance,sorted the results according to the influence degree,found the independent risk factors:common bile duct internal diameter (B Ultrasound) ≥8 mm,gallbladder removal order (retrograde removal),medical history of jaundice pancreatitis,cystic duct reserved ≥ 1 cm,sludge calculus,in total of 5 indexes,which caused the retained CBD stones after laparoscopic cholecystectomy.Conclusion There are several independent risk factors for retained CBD stoes after LC such as medical history of jaundice and pancreatitis,common bile duct internal diameter (B Ultrasound) ≥ 8 mm,the order of cholecystectomy (retrograde remoral),shudeg calculus and the remaining length of bile duct ≥ 1 cm.The surgeons should pay close attention to them and take appropriate measures in the preoperation and intraoperation of LC,which contribute to preventing the acurence of postoperative retaimed CBD stone.
