Objective To evaluate effects of two different preoperative biliary drainages on patients of malignant obstructive jaundice complicated with acute cholangitis.Methods Retrospective analysis was made on effects of two preoperative biliary drainages of ultrasound-guided percutaneous transhepatic cholangial drainage (PTCD) and endoscopic nasobiliary drainage (ENBD) in cases of malignant obstructive jaundice complicated with acute cholangitis.Results Days of preoperative drainage(t =3.217,P ＜ 0.05) and declines of bilirubin level after drainage (t =3.178,P ＜ 0.05) were significantly better in ENBD group (26 cases) than PTCD group (22 cases).There were no significant differences between two groups in operation time length and intraoperative blood loss after drainage.However,postoperative hospital stay (t =2.542,P ＜ 0.05) and overall stay (t =3.172,P ＜ 0.05) were significantly shorter in ENBD group compared with PTCD group.Conclusions When preoperative biliary drainage is indicated in the cases of malignant jaundice before radical surgery,ENBD should be the first choice over DTCD.

Objective To study the effect of percutaneous transhepatic gallbladder drainage (PTGBD) combined with laparoscopic cholecystectomy (LC) in treatment of acute severe cholecystitis.Method The perioperative data of patients treated with PTGBD combined with LC and patients treated with emergency LC were analyzed.Results There were no significant difference between the two groups on surgical duration (t =0.601,P =0.551) and postoperative hospital stay (t =0.979,P =0.331).Blood loss [PTGBD + LC (79.43 ± 46.27) ml,LC (125.84 ± 64.18) ml ; t =3.641,P ＜ 0.05],peritoneal drainage time [PTGDB + LC (3.29 ± 1.58) d,LC (4.63 ± 2.31) d ; t =3.131,P ＜ 0.05] and postoperative oral intake time [PTGBD +LC (2.91 ±1.58)d,LC (4.21 ±2.22)d; t =2.669,P＜0.05] were significantly different between the two groups.The rate of laparotomy,mortality and postoperative complications in the emergency LC group were higher than those in the PTGBD combined with LC group.Conclusions PTGBD combined with LC in the treatment of acute severe cholecystitis was significantly better than emergency LC.

Objective To evaluate the diagnosis and treatment of residual gallbladder.Methods The diagnosis of residual gallbladder depends on a history of previous cholecystectomy and postoperative existent symptoms suggesting cholecystitis.In this series the diagnosis was finally established by ultrasonography and laparotomy in 52 cases.Results Ten cases received laparoscopic residual cholecystectomy,32 cases underwent residual cholecystectomy,7 cases did residual cholecystectomy plus common bile duct exploration,1 case was treated with residual cholecystectomy,common bile duct exploration and left lateral lobe hepatectomy,1 case with residual cholecystectomy,common bile duct exploration,cholangioenterostomy,1 case by radical resection of residual gallbladder cancer.Conclusions Residual gallbladder is a secondary disease,diagnosis is not difficult,surgery has certain difficulty,the application of intraoperative ultrasound and choledochoscope has great value.
