Congenital bile duct cysts, which is a kind of malformation of bile duct, will lead to the inflammation in the bile duct system for a long time. Therefore, patients with cholelithiasis and cyst canceration have a risk. Surgical operation is the only treatment option for the congenital bile duct cysts patients. Resection of the cysts and complete " biliary-pancreatic duct shunt" are the key points of the standardized treatment of congenital bile duct cysts. The non-standard surgical treatment will bring the postoperative complications such as the stricture of choledochojejunostomy, the remnant cysts and even the canceration of cysts, which will seriously affect the quality of life and threaten the health of patients. Based on the retrospective study of congenital bile duct cysts patients in Eastern Hepatobiliary Hospital, the author proposed a new classification system according to the pathological and anatomical characteristics of congenital bile duct cysts. The congenital bile duct cysts can be divided into three regions and five types, i. e. localized type and diffuse type of extrahepatic bile duct cysts of hilar, trunk and terminal type; central type; and intrahepatic bile duct cysts of limited and diffuse type. It is our hope that this typing system will accurately guide the design and implementation of surgical treatment plans for congenital bile duct cysts and reduce the risk of long-term postoperative complications for patients.

Gallbladder carcinoma (GC) is the most common malignant tumor in bile duct system.Xanthogranulomatous cholecystitis (XGC) is a benign inflammatory gallbladder disease.It is often misdiagnosed between them.This paper,through reviewing the literature and summarizing our own clinical experience,will give a better understanding on the two diseases,which was summarized as follows:inflammation is important both in the pathogenesis of GC and XGC,and we can make the correct diagnosis and choose an appropriate treatment by analy zing the feature of disease history,image data and rapid intraoperative pathological diagnosis.Radical resection remains the first choice in the treatment of GC,but the extent of resection is controversial.Normally,cholecystectomy is sufficient for curing XGC,but different surgeries are needed according to the specific disease conditions.

Objective To retrospectively study the clinical value and the advantages in " planned hepatectomy" for the "central type" intrahepatic and extrahepatic choledochal cysts.Methods The clinical data of 7 patients with the "central type" of intrahepatic and extrahepatic choledochal cysts which were treated with "planned hepatectomy" from January 2014 through April 2017 at the Department of Biliary Tract Surgery of the Eastern Hepatobiliary Surgery Hospital,Second Military Medical University were retrospectively analyzed.Results All the patients completed radical resection of the intrahepatic and extrahepatic choledochal cysts in accordance with the " planned hepatectomy".The operations included 6 patients who were treated with percutaneous transhepatic cholangial drainage (PTCD) and 5 patients with portal vein embolization (PVE) prior to the surgical excision.Combined right liver resection was performed in 6 patients,and combined left liver resection in one patient.All the 7 patients had a history of chronic cholangitis.Liver volume tests demonstrated that the hemiliver volume to be removed (the embolized hemiliver) significantly decreased after PVE,whereas the hemilivers to be persevered were remarkably enlarged.No complication associated with PTCD and PVE occurred.The mean postoperative hospitalization was 12 days.Liver function tests suggested all the patients recovered well.No postoperative complication of bleeding,infection or liver function failure was observed,except in one patient who experienced pleural and abdominal effusion.Conclusions Combined subtotal hepatectomy may increase the risk of complications associated with the "central type" intrahepatic and extrahepatic choledochal cysts.The surgical strategy in planned hepatectomy can be used effectively to treat the "central type" of intrahepatic and extrahepatic choledochal cysts,with improved surgical safety,decrease in incidences of postoperative liver function failure and residual choledochal cysts.

Objective To investigate the risk factors for postoperative liver failure of patients with hepatocellular carcinoma (HCC) and bile duct tumor thrombus through a risk evaluation model.Methods The clinical data of 107 patients with HCC and bile duct tumor thrombus who received hepatic resection at the Eastern Hepatobiliary Surgery Hospital from March 2002 to February 2011 were retrospectively analyzed.All patients were divided into the non-liver failure group (98 patients) and liver failure group (9 patients).Risk factors associated with liver failure were analyzed and a risk evaluation model was established.All data were analyzed using the bivariate regression model,and factors with significance were further analyzed using the multivariate regression model.Results Of the 107 patients,105 received hepatic resection + choledochotomy + thrombectomy and 2 received hepatic resection + extrahepatic bile duct resection + cholangiojejunostomy.The operation time was 2.0-5.5 hours,and the intraoperative blood loss was 200-3500 ml.In the non-liver failure group,5 patients had pleural and peritoneal effusion,3 had biliary bleeding,2 had incisional infection,1 had biliary infection,1 had bile leakage,1 had stress-induced ulcer of upper digestive tract and 1 had thoracic epidural hematoma.The bleeding of the patients with thoracic epidural hematoma was stopped after thoracic spinal decompression,but subsequent paraplegia occurred.In the liver failure group,2 patients died of postoperative acute liver failure,and 7 patients died of postoperative subacute liver failure (death caused by tumor recurrence or medicine was excluded).The results of univariate analysis showed that preoperative total bilirubin,albumin,pre-albumin,albumin/globulin ratio,distribution of tumor thrombus,operative blood loss and ratio of postoperative residual liver volume to the total liver volume were correlated with the postoperative liver failure in patients with HCC and bile duct tumor thrombus (OR =3.017,0.191,0.248,2.681,9.048,4.759,13.714,P < 0.05).The results of multivariate analysis showed that preoperative total bilirubin > 256.5 μmol/L,albumin/globulin ratio ≤ 1.3 and postoperative residual liver volume < 50% were the independent risk factors of postoperative liver failure (OR =5.537,11.107,172.450,P < 0.05).The risk evaluation model was Z =1.77 × preoperative total bilirubin + 2.408 × preoperative albumin/globulin ratio + 5.150 × ratio of postoperative residual liver volume to the total liver volume-17.288.The risk of postoperative liver failure increased as the increase of Z value.The risk of postoperative liver failure > 50% when the Z value > 0.Conclusions Preoperative total bilirubin > 256.5μmol/L,albumin/globulin ratio ≤ 1.3 and postoperative residual liver volume < 50% were the independent risk factors of postoperative liver failure.Risk evaluation model is helpful in screening the risk factors so as to decrease the incidence of postoperative liver failure.
