Objective To investigate the double T tube drainage method in the treatment of hepatic echinococcosis which ruptured into the common bile duct.Methods A retrospective study was conducted on 86 patients who were treated surgically for hepatic echinococcosis which had ruptured into the common bile duct at the First Affiliated Hospital of Xinjiang Medical University from June 2012 to December 2014.The average postoperative hospitalization,postoperative complications (residual cavity bile leakage and residual cavity effusion,residual cavity infection) and biliary complications of biliary tract infection were analyzed.Results Significant differences were found on the postoperative residual cavity complications in group A:(2,7.1％) when compared with Group B:(9,15.5 ％),and also on the postoperative hospitalization between the double T tube drainage group [group A:(7.1 ± 1.3) d] and the traditional T type tube decompression group [B group:(8.2 ± 1.5) d] (P ＜ 0.05).Conclusions The doubleT tube drainage in the treatment of hepatic echinococcosis which had ruptured into the common bile duct was simple,safe and effective.This treatment could completely cure residual cavity bile leakage,and it had the advantage of avoiding occurrence of common bile duct related complications caused by the traditional suture method for bile leakage.
