【Abstract】ObjectiveTo investigate whether abnormal expression of β-catenin and high expression of c-myc have played a possible role in hilar cholangiocarcinoma carcinogenesis.MethodsBy using immunohitochemical staining (SP method), the authors detected the expression of β-catenin and c-myc in 42 paraffin-embedded samples of hilar cholangiocarcinoma and 10 benign bile duct disease tissue, and then analyzed the relationship of them with clinical data. Resultsβ-catenin was normally expressed in 10 benign bile duct disease tissue, while expression of c-myc was negtive. In hilar cholangiocarcinoma tissue, the positive expression rate of β-catenin （71.4%） was significantly correlated to the lymphoid node metastasis of hilar cholangiocarcinoma (χ2=4.75，P＜0.05),but was not statistically correlated to the tumor size，the extent of differentiation and infiltration (χ2=3.35，3.45，4.32，Pgt;0.05); the expression rate of c-myc (76.2%) was correlated with the extent of differentiation(χ2=4.87, P＜0.05),but not with the size, infiltration, lymphoid metastasis（χ2= 3.47，4.12，2.76， Pgt;0.05). The abnormal expression of β-catenin had relevance to the high expression of c-myc with hilar cholangiocarcinoma （r=0.324,P＜0.01）. ConclusionThe expression of beta-catenin and c-myc is significantly altered in hilar cholangiocarcinoma, and correlate with biological features of cholangiocarcinoma.The abnormal expression of beta-catenin is one of the mechanisms for the spread of hilar cholangiocarcinoma.
ObjectiveTo discuss the effect of palliative drainage operation on the life quality of hilar cholangiocarcinoma. MethodsCholangiocarcinoma data of our hospital in recent 21 years were analysed retrospectively. They were divided into four groups: RouxenY choledochojejunostomy group, bridge internal drainage group, PTCD (or ERBD) internal drainage group, and operative external drainage group. The operative mortality, incidence of postoperative cholangitis and survival period were compared among groups.ResultsThe total perioperative mortality of 193 cases of palliative operation was 9.3%, there was no difference among groups (P＞0.05). The rate of postoperative cholangitis in the bridge internal drainage group (10.0%) was lower than that of RouxenY choledochojejunostomy group (19.4%),P＜0.05, the rate of cholangitis in PTCD (or ERBD) internal drainage group (37.5%) and operative external drainage group (38.1%) were significantly higher than that of RouxenY choledochojejunostomy group (P＜0.01). There was no significant difference between RouxenY choledochojejunostomy group 〔(9.2±1.8) months〕 and PTCD (or ERBD) internal drainage group 〔(8.8±1.9) months〕 in survival period (P＞0.05)，but the survival period of the above groups were significantly higher than that of bridge internal drainage group 〔(6.5±1.6) months〕，P＜0.05, and operative (or PTCD) external drainage group 〔(4.3±2.0) months〕,P＜0.01.ConclusionThe life quality of RouxenY choledochojejunostomy group is better than that of bridge internal drainage group and PTCD (or ERBD) internal drainage group, the life quality of external drainage is worse than that of the other groups.
Objective To establish perineural invasion xenograft model of hilar cholangiocarcinoma. Methods The cultured cells of cholangiocarcinoma cell line QBC939 were inoculated subcutaneously in the nude mice so as toestablish primary subcutaneous model of cholangiocarcinoma. The primary tumor tissues were inoculated intraperitoneallyaround the liver in the nude mice so as to establish the second generation intraperitoneal xenograft model. The successful xenografted tumor tissues were obtained for anatomical and pathological examinations. Results The tumor formation rate of primary subcutaneous xenograft of hilar cholangiocarcinoma was 100% （5/5）， and no nerve infiltration was observed. The tumor formation rate of the second generation intraperitoneal xenograft was 45% （9/20）， and two mice （2/9， 22%） manifested nerve infiltration. The rate of nerve infiltration was 10% （2/20）， and the tumor cells had different size and diversity， irregular shape， low differentiation， decreased cytoplasm and nucleus karyomegaly， visible atypical and fission phase， and no obvious gland tube structure by pathological examination. Conclusions Hilar cholangiocarcinoma cell has the particular features of perineural invasion， it is a good experiment platform for researching the mode and biological characteristics of perineural invasion of hilar cholangiocarcinoma by applicated QBC939 cell lines to establish the perineural invasion xenograft model of cholangiocarcinoma.
ObjectiveTo summarize the clinical experience of 58 operations for biliary malignant tumor with da Vinci surgical system. MethodsFrom January 2009 to October 2010, 180 patients with hepatopancreaticobiliary and gastrointestinal disease underwent robotic surgeries by using da Vinci surgical system, including 58 patients with biliary malignant tumor. The case distribution, intra and postoperative data were analyzed. ResultsOf 58 patients, 3 patients with intrahepatic bile duct cystadenocarcinoma received wedge resections of liver. In 36 patients with hilar cholangiocarcinoma, anatomical left hemihepatectomies were performed in 3 cases, resection of extrahepatic duct and gallbladder bridge type biliary revascularization in 3 cases, resection of extrahepatic duct and biliary-enteric Roux-en-Y anastomosis in 14 cases, tumor resection and revascularization of hepatic portal bile duct in 1 case, palliative external drainage of intrahepatic bile duct in 5 cases, and Y-internal drainage of hepatic portal in 10 cases. In 10 patients with gallbladder carcinoma, resection of extrahepatic duct and gallbladder and biliaryenteric Roux-en-Y anastomosis in 2 cases, cholecystectmy in 3 cases, cholecystectmy and external drainage of intrahepatic bile duct in 1 case, cholecystectmy and Y-internal drainage by suspension of hepatic portal in 4 cases. A patient with middle bile duct cancer received radical resection of cholangiocarcinoma and biliary-enteric Roux-en-Y anastomosis. Of 8 patients with distal bile duct cancer, Whipple procedure were performed. Of 58 patients, 2 cases converted to hand-assistant procedure (3.4%). For all patients, operation time was (6.18±1.71) h, blood loss was (116.66±56.06) ml, blood transfusion was (85.55±38.28) ml, ambulation time was (9.10±2.91) h, feeding time was (14.95±4.35) h, and hospital stay was (12.81±4.29) d. Postoperative complications occurred in 8 cases (13.8%), including bile leakage (3 cases), wound bleeding (1 case), pancreatoenteric anastomotic leakage (2 cases), pulmonary infection (1 case), and renal failure (1 case). Of these 8 cases, 6 cases recovered smoothly and 2 cases die of severe pulmonary infection and renal failure after conservative treatment (3 or 4 weeks), therefore, the mortality of patients was 3.4%. In 36 patients with hilar cholangiocarcinoma, 19 cases died (on 2 monthes 4 cases, on 6 monthes 5 cases, on 10 monthes 8 cases, and on 12 monthes 2 cases after operation), 11 cases survival well (gt;26 monthes 4 cases, gt;22 monthes 3 cases, and gt;19 monthes 4 cases), and 6 cases required hospitalization. Of 10 patients with gallbladder carcinoma, 7 cases died (on 3 monthes 1 case, on 5 monthes 1 case, on 8 monthes 1 case, on 11 monthes 3 cases, and on 12 monthes 1 case after operation) and 3 cases survival (gt;17 monthes 2 cases, gt;13 monthes 1 case). In 8 cases undergoing pancreatoduodenectomy, 5 cases died (on 4 monthes 2 cases, on 6 monthes 2 cases, and 10 monthes 1 case after operation) and 3 cases survived well over 2 years. Three patients with intrahepatic bile duct cystadenocarcinoma survived over 1 year. Conclusionsda Vinci surgical system can carry out all kinds of surgery for biliary malignant tumor, especially prominent in the complicated surgeries for hepatic portal, which breaks through the restricted area of laparoscope in hepatobiliary malignant tumor.
ObjectiveTo discuss the treatment methods and outcome of hilar cholangiocarcinoma. MethodsFrom January 2002 to December 2008, 81 cases of hilar cholangiocarcinoma were retrospectively analyzed. ResultsAmong 81 patients, there were 55 males and 26 females, ages were from 38 to 72 years with an average age 57.5 years. In BismuthCorlette classification, 5 cases were type Ⅰ, 15 cases type Ⅱ, 14 cases type Ⅲa, 14 cases type Ⅲb, 33 cases type Ⅳ, according to the preoperative results of MRCP, but the classification of 15 cases were not consistent to the preoperative results (5 cases type Ⅱ, 8 cases type Ⅲ, 2 cases type Ⅳ) according to the results of intraoperative exploration. The rates of complications of radical operation, palliative operation, internal biliary drainage, and external biliary drainage were 54.5%(12/22), 58.8%(10/17), 23.8%(5/21), and 66.7%(14/21), respectively. The rate of complications of internal biliary drainage was lower than that of the other three methods (Plt;0.01), there were no significant differences among the other three methods. The 1, 2, 3, and 5year survival rates of 22 patients with radical operation, 17 patients with palliative operation, 21 patients with internal biliary drainage, 21 patients with external biliary drainage were 75.0%, 60.0%, 38.3%, 2.6%; 72.7%, 26.5%, 4.2%, 0; 50.5%, 15.8%, 2.2%, 0; 30.6%, 8.5%, 0, 0, respectively. The median survival time was 29.5 months, 13.8 months, 10.5 months, and 8.3 months, respectively. Survival rate of radical operation was higher than that of palliative operation (χ2=14.20, P=0.000 3), palliative operation was higher than that of internal biliary drainage (χ2=4.50, P=0.040 5), and internal biliary drainage was higher than that of external biliary drainage (χ2=4.45, P=0.040 1). ConclusionsThe BismuthCorlette classification is a guide to the required surgery, but the results of intraoperative exploration decides the final classification and operative method. Radical resection is the main related factors influencing the therapy efficacy of hilar cholangiocarcinona. Basinstyle anastomosis and T type supportingtube is the first choice of palliative operation. External drainage, to the full, is avoided.
【Abstract】ObjectiveTo report the diagnosis and treatment of hilar cholangiocarcinoma.MethodsThe relevant information about the hispathological feature, transfer ways, clinical manifestation, laboratory examination, imaging feature, immunohistochemical examination and treatment ways were gathered from previous original articles, and checking the latest issues of appropriate journals.ResultsThe clinical manifestation, laboratory examination, and imaging feature of hilar cholangiocarcinoma were due to the neoplasm obstructing bile duct and sequent infection of bile duct. The diagnosis was depanded on the combining clinical manifestation, laboratory examination and imaging feature. The value of immunohistochemical examination was not clear. Radical surgery was the best treatment of unique curing the neoplasm. By-pass surgery was used in the late phase patients to solve the obstruction of bile and digest duct. The effect of unique chemical treatment was not perfect. It did’t generally propose the treatment of orthotopic liver transplantation.ConclusionThe perfect prognosis of hilar cholangiocarcinoma is depended on early diagnosis and redical surgery.
Objective To improve the curative resection rate of hilar cholangiocarcinoma (H-CC).Methods Lileratures about surgical treatment of H-CC were collected and reviewed. Results The crucial points are as follow: ①Early diagnosis; ②Recognition of the invasion to liver; ③Rational resection of the tumor with associated vessels; ④Reduction of postoperative complications. Conclusion Improved longterm resection effects on H-CC is possible.
Objective To discuss the relationship between the efficiency of bile duct drainage and the postoperative liver functional recovery and the prognosis of hilar cholangiocarcinoma. Methods We studied retrospectively 58 cases of hilar cholangiocarcinoma which entered our department between June 1987 and October 1998. The postoperative liver functional recovery and mortality and morbidity between unilateral (n＝27) and bilateral (n＝31) bile duct drainage groups were compared. Results The liver function in bilateral drainage group was nearly normal within 6 weeks after operation. The ALb level of unilateral drainaged patients recovered gradually to normal after operation, and the TBIL and ALT decrease nearly to the normal range within 6 weeks after operation. The AKP decreased within 2 postoperative weeks, then steadily increased. The differences of perioperative complication rate and mortality of the two groups showed no significance. Conclusion The data showed that the liver function can recover to some extent by unilateral bile duct drainage, and unilateral drainage operations are the choice for hilar cholangiocarcinoma that can not be excised now.
ObjectiveTo analyze effect of percutaneous transhepatic choledochus drainage (PTCD) for hilar cholangiocarcinoma. MethodsClinical data of 67 cases of hilar cholangiocarcinoma who treated in our hospital from Jan. 2005 to Dec. 2010 were retrospectively analyzed. ResultsOf the 67 cases, 30 cases were performed PTCD, 20 cases were performed radical surgery after PTCD, and 17 cases were performed palliative surgery after PTCD. There were 59 cases who were followed-up for 3-30 months, and the median time was 9.3 months. The median survival time of patients who underwent PTCD, radical surgery, and palliative surgery were 10.2, 21.4, and 8.9 months respectively. The survival of patients who underwent radical surgery was better than those of underwent PTCD (χ2=13.6, P=0.000 4) and palliative surgery (χ2=15.2, P=0.003 8), and survival of patients who underwent PTCD was better than patients underwent palliative surgery (χ2=5.3, P=0.040 1). ConclusionsPTCD is contribute to preoperative diagnosis and evaluation, in addition, it can reduce unnecessary surgical exploration, guarantee the safety of the radical surgery, and provide follow-up care for palliative operation channel which is favorable for local internal radiation therapy.
ObjectiveTo summarize the surgical treatment and explore factors which influencing prognosis of hilar cholangiocarcinoma. MethodsClinical data of 189 cases of hilar cholangiocarcinoma who treated in our hospital from Jan. 2000 to Dec. 2010 and clinicopathological factors that might influence survival were analyzed retrospectively. A multivariate factor analysis was performed through Cox proportional hazard model. ResultsOf 189 cases, 62 cases received radical resection, 54 cases received palliative surgery, and 73 cases received non-resection surgery. Operative procedure (RR=0.165), differentiated degree (RR=2.692), lymph node metastasis (RR=3.014), neural infiltration (RR=2.857), and vascular infiltration (RR=2.365) were found to be the statistically significant factors that influenced survival by multivariate factor analysis through the Cox proportional hazard model. ConclusionsRadical resection is the best treatment for hilar cholangiocarcinoma. Skeletonized hepatoduodenal ligament, complete excision of infiltrated nerve and blood vessel are important influence factors to improve the prognosis of hilar cholangiocarcinoma.
