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.
ObjectiveTo understand the current situation of surgical treatment of hilar cholangiocarcinoma. MethodThe literature relevant to surgical treatment of hilar cholangiocarcinoma at home and abroad in recent years was reviewed. ResultsThe various surgical treatment schemes of hilar cholangiocarcinoma had advantages and disadvantages. At present, there were still disputes and no unified consensus on preoperative preparation, selection of intraoperative surgical resection range, and applications of laparoscopy and robot, etc. The individualized surgical treatment plan should still be formulated based on the specific condition of the patient and the professional experience of the surgeon. The individualized surgical treatment plan should still be formulated based on the specific condition of the patient and the professional experience of the surgeon. ConclusionIt is believed that accurate preoperative condition evaluation should be carried out for each patient with hilar cholangiocarcinoma, so as to formulate the best surgical treatment plan, achieve individualized accurate treatment and benefit patients.
肝门部胆管癌（hilar cholangiocarcinoma），又称Klaskin癌，是指起源于左右肝管、分叉部和肝总管上段胆管上皮的恶性肿瘤，约占胆管癌的60%~70%［1］。由于其临床表现隐匿，早期难以被发现。目前根治性手术是最有效的提高其生存率的治疗方式，随着肝门部胆管癌R0切除率的不断升高，5年生存率不断提高［2，3］，但仍有不少问题有待于解决……
ObjectiveTo explore the technique of hepatic artery reconstruction in complicated hilar cholangiocarcinoma surgery. MethodThe clinicopathologic data of 3 patients with complicated hilar cholangiocarcinoma with arterial invasion underwent hepatic artery reconstruction in the Department of Hepatopancreatobiliary Center of Beijing Tsinghua Changgung Hospital from March to July 2022 were retrospectively analyzed. ResultsAll 3 patients (case 1–3) were the males, aged 53, 68, and 56 years, respectively, and with hypertension or diabetes; the longitudinal diameters of the tumor were 3.5 cm, 3.0 cm, and 3.2 cm, respectively. All patients had the right hepatic artery invasion. Case 2 and 3 had the arterial stratification. The arterial defects after radical resection were 4.5 cm, 3 cm, and 3 cm, respectively. The right or right posterior hepatic artery was reconstructed by the autotransplantation of right gastroomental artery, the left hepatic artery, and the anterior superior pancreaticoduodenal artery, respectively. After operation, the reconstructed hepatic arteries were unobstructed and free of stenosis, and there were no complications such as bleeding, infection, and thrombosis by Doppler ultrasound and CT angiography. The results of postoperative pathological diagnosis were the hilar cholangiocarcinoma with arterial invasion, and all the incisal edges were negative. ConclusionFrom the preliminary results of 3 cases, it is safe, feasible, and effective to select proper autologous artery (matched in length and caliber) for reconstruction the defective invaded hepatic artery which resected together with hilar cholangiocarcinoma, but the technical difficulty is still relatively high.
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 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 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.
