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 explore safety and efficacy of total laparoscopic radical resection of hilar cholangiocarcinoma. Methods From April 2016 and January 2017, 6 patients with hilar cholangiocarcinoma underwent laparoscopic radical resection in the Affiliated Hospital of Xuzhou Medical University were collected. The intra- and post-operative situation and the postoperative complications were analyzed. Results The radical resections of hilar cholangiocarcinoma were completed laparoscopically in all the patients. There was no conversion to the laparotomy. The procedure was finished within a time of (231.3±94.5) min and with an intraoperative blood loss of (123.3±46.8) mL. The first postoperative exhausting time and the postoperative hospital stay was (2.7±0.3) d and (11.9±1.7) d, respectively. All the patients had the R0 resection and the numbers of dissected lymph nodes were 9.4±2.7. The postoperative complications occurred in 2 patients, they were all cured spontaneously in one week, and there was no perioperative death. None of patients had a local recurrence and metastasis during an average 8 months of following-up. Conclusions Preliminary results of limited cases in this study show that with suitable case and skillful laparoscopic technique, laparoscopic radical resection of hilar cholangiocarcinoma is feasible and safe. Further studies are still needed to confirm benefits of this approach.
ObjectiveTo explore the advantages and disadvantages of preoperative biliary drainage, the timing of preoperative biliary drainage, and the characteristics of various drainage methods for resectable hilar cholangiocarcinoma.MethodsBy reviewing relevant literatures at home and abroad in the past 20 years, the controversies related to the preoperative biliary drainage, surgical biliary drainage, and various drainage methods for resectable hilar cholangiocarcinoma were reviewed.ResultsThere is still a great deal of controversy about whether preoperative bile duct drainage is required for resectable hilar cholangiocarcinoma routinely, but there is a consensus on the timing of preoperative biliary drainage, and various drainage methods have their own characteristics.ConclusionsThe main treatment for hilar cholangiocarcinoma is radical surgical resection, but cholestasis is often caused by malignant biliary obstruction, which makes it difficult to manage perioperatively. A large number of prospective studies are needed to provide more evidence for the need for routine preoperative biliary drainage in patients with hilar cholangiocarcinoma who can undergo resection.
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.
Objective To explore application value of photodynamic therapy (PDT) in treatment of unresectable hilar cholangiocarcinoma. Method The literatures about PDT in the treatment of the unresectable hilar cholangiocarcinoma in the PubMed, MedLine, Embase, CNKI, and Wanfang databases were reviewed. Results The PDT combined with stent or chemotherapy was the main method in the treatment of the unresectable hilar cholangiocarcinoma, which could make the tumor down-staging, obviously reduce the jaundice, improve the quality of life, improve the survival rate, prolong the stent patency and be treated repeatedly. Especially, it was suitable for the patients with elderly, poor health, intolerance of surgery, could partly replace the R1 or R2 operation of hilar cholangiocarcinoma and avoid the risk of surgery and postoperative complications. The therapeutic effective of the PDT was related to the early therapy and times of therapy. However, the shortcomes of the PDT were that the depth of killing tumor was not enough and there was a certain incidence of adverse reaction. Conclusions Therapeutic effect of PDT combine with stent or chemotherapy for unresectable hilar cholangiocarcinoma is better than that of single therapy. It is expected to be a first-line scheme of palliative treatment for unresectable hilar cholangiocarcinoma.
ObjectiveTo overview the various molecular biological index to judge the prognosis of intrahepatic cholangiocarcinoma (ICC), in order to promote ICC patients follow-up treatment, improve survival rate, and quality of life of the patients. Methods"ICC" and "prognostic factor" were searched as key words by PubMed and CNKI series full-text database retrieval systems from 2000 to 2015. Totally 48 English papers and 15 Chinese papers were obtained. Choice criteria:the molecular biological index that affect the prognosis of ICC patients, and can effectively guide treatment. According to the choice criteria, 45 papers were finally analyzed. ResultsThe indicators of Homer1, mucin 1 (MUC1)\mucin 4 (MUC4), lactate dehydrogenase A (LDH-A), Beclin1, Smad4, protein tyrosine kinase-7 (PTK7), IMP3, cytokeratin 7 (CK7)/cytokeratin 20 (CK20), and sphingosine kinase 1 (SPHK1) could be used as prognostic factors in the survival of patients with ICC, and to determine tumor size and stage, vascular invasion, nerve injury, and lymph node metastasis, are of great clinical significance. ConclusionThese indicators have a significant meanning in the prognosis of ICC and the adjustment of the follow-up treatment.
ObjectiveTo detect expression of FXYD6 protein in hilar cholangiocarcinoma tissues and explore its significances. MethodsThe expressions of FXYD6 protein in the 58 hilar cholangiocarcinoma tissues and 30 normal bile duct tissues adjacent to cancer were detected by strept avidin-biotin complex (SABC) immunohistochemistry. The relation between FXYD6 protein expression and biological characteristics of patient with hilar cholangiocarcinoma was analyzed. ResultsThe positive rate of FXYD6 protein expression in the hilar cholangiocarcinoma tissues was significantly higher than that in the normal bile duct tissues adjacent to cancer[75.9% (44/58) versus 33.3% (10/30), χ2=15.084, P=0.000]. Furthermore, the positive rate of FXYD6 protein expression in the well and moderately differentiated hilar cholangiocar-cinoma tissue was significantly higher than that in the poorly differentiated hilar cholangiocarcinoma [85.4% (35/41) versus 52.9% (9/17), χ2=5.243, P=0.022], which was not related to the gender (χ2=0.000, P=1.000), age (χ2=1.248, P=0.264), T stage (χ2=0.466, P=0.495), lymph node metastasis (χ2=0.357, P=0.550), pathological stage (χ2=0.005, P=0.944), and perineural invasion (χ2=3.016, P=0.082). Conclustion The positive rate of FXYD6 protein expression is associated with differentiation of hilar cholangiocarcinoma, which might be a new biomarker of it.
ObjectiveTo explore the clinical significance of hepatectomy combined with vascular reconstruction in hilar cholangiocarcinoma with vascular invasion. MethodsThe clinical data of 62 cases of hilar cholangiocarcinoma with vascular invasion in Suqian People's Hospital of Nanjing Drum-Tower Hospital Group from January 2006 to January 2014 were analyzed retrospectively. All cases were divided into two groups according to assessment of surgical trauma tolerance, nutritional status, and family's wishes. Thirty-three cases underwent hilar cholangiocarcinoma radical operation and hepatic artery combined with portal vein resection and reconstruction (combined resection group), while 29 cases of hilar cholangiocarcinoma underwent palliative surgery for treating jaundice in synchronization (palliative operation group). ResultsThe median survivals in combined resection group and palliative operation group was 26.3 and 9.6 months, respectively. The survival rates of 1-year, 2-year, and 3-year between combined resection group and palliative operation group were 84.85% vs. 26.32%, 66.67% vs. 15.79%, and 42.42% vs. 0, respectively, there were significant differences between both groups in survival time and survival rate (t=4.470, P=0.000; χ2=28.338, 20.348, and 15.891, P=0.000). Among of 33 cases in combined resection group, postoperative complications occurred in 9 cases, the rate of complications was 27.27% and the mortality rate in perioperative period was 3.03%; while postoperative complications in palliative operation group occurred in 5 cases, the rate of complications was 17.24%, no case died in the perioperative period. There were no significant difference between both groups in the rate of postoperative complications and the mortality rate in perioperative period (χ2=0.888, P=0.346; χ2=0.893, P=0.345). ConclusionsHepatectomy combined with vascular resection and reconstruction can significantly improve the radical resection (R0) rate of HCCA, and greatly increase the 1-year, 2-year, and 3-year survival rates of patients. Furthermore, complications can be controlled, and the mortality rate in perioperative period does not increase.
ObjectiveTo investigate the expression of forkhead box A2 (FXOA2) in intrahepatic cholangiocarcinoma (ICC), and to analyze the relationship between expression of FOXA2 and patient's prognosis after liver resection. MethodsData of 85 patients with ICC who underwent liver resection between 2009 and 2013 in our hospital were collected retrospectively. The expression of FOXA2 was examined by immunohistochemical method, and then the relationship between expression of FOXA2 and patient's prognosis/clinical characteristics was expplored. ResultsAmong the 85 patients, low expression of FOXA2 was detected in 50 patients, whereas high expression was observed in 35 patients. More advanced tumor (Ⅲ+Ⅳ staging) was found in patients with low expression of FOXA2 than patients with high expression of FOXA2 (P < 0.050). The median follow-up time was 15-month (3-73 months). During the follow-up period, 65 patients suffered from recurrence, whereas 64 patients died. The multivariate analysis suggested that, postoperative recurrence was associated with low expression of FOXA2, evaluated preoperative CA19-9, and presence of satellite nodes (P < 0.050). Low expression of FOXA2, evaluated preoperative CA19-9, nerves invasion, and presence of satellite nodes were predictive factors for postoperative prognosis (P < 0.050). ConclusionLow expression of FOXA2 was associated with poor prognosis for patients with ICC after liver resection, and FOXA2 may be a prognostic factor for ICC.
ObjectiveTo investigate the expression level of exosome microRNA-21 (miRNA-21) in the bile and its clinical diagnostic value for the patients with cholangiocarcinoma. MethodsIn this study, 45 cases of cholangiocarcinoma admitted to Dongfeng General Hospital from August 2019 to December 2021 and met the inclusion criteria were selected and 35 patients with benign diseases of bile duct (choledocholithiasis or benign stricture of bile duct) during the same period were selected as control. The exosome in the bile was extracted by hypervelocity centrifugation method and identified. The exosome miRNA was extracted from the bile using a kit, then the expression level of miRNA-21 was detected by real-time fluorescent quantitative PCR. The diagnostic value of exosome miRNA-21 in the bile for cholangiocarcinoma was analyzed by receiver operating characteristic curve (ROC). ResultsThe isolated exosome in the bile conformed to the characteristics of recognized exosome and the concentration was higher. The average expression level of exosome miRNA-21 in the bile of the patients with cholangiocarcinoma was statistically higher than that in the patients with benign diseases of bile duct (59.45 verses 25.41, t=3.445, P<0.001). The area under the ROC curve was 0.715 [95%CI (0.602, 0.827), P=0.001]. The sensitivity and specificity of miRNA-21 in the diagnosis of cholangiocarcinoma were 75.6% and 62.9%, respectively. ConclusionFrom the results of this study, exosome miRNA-21 expression in bile is higher and it may be a potential early diagnostic marker for patients with cholangiocarcinoma.
