Objective To explore primary surgical treatment experience of typeⅣ hilar cholangiocarcinoma. Methods From April 2008 to April 2011，20 patients with type Ⅳ hilar cholangiocarcinoma were enrolled into the same surgical group in Department of Hepatobiliary and Pancreatic Surgery of West China Hospital of Sichuan University.The intra- and post-operative results were analyzed.Results The total resection rate was 75%，which was consisted of 10 cases of radical excision and 5 cases of non-radical excision.Seven patients received left hepatic trisegmentectomy and caudate lobe resection including anterior and posterior right hepatic duct reconstruction，hepatojejunostomy，and Roux-en-Y jejunojejunostomy.Six patients received enlarged left hepatic trisegmentectomy and caudate lobe resection including left intrahepatic and extrahepatic duct reconstruction，hepatojejunostomy，and Roux-en-Y jejunojejunostomy. Two patients received quadrate lobe resection including two cholangioenterostomies after anterior and posterior right hepatic duct reconstruction，and left intrahepatic and extrahepatic duct reconstruction.After percutaneous transhepatic cholangial drainage （PTCD） and portal vein embolization （PVE），two patients with total bilirubins ＞400 mmol/L received radical excision and non-radical excision，respectively.Three patients only received PTCD during operation due to wide liver and distant metastasis，and two patients received T tube drainage during operation and postoperative PTCD due to left and right portal vein involvement. All 15 patients who received lesion resection survived more than one year， whereas another five patients whose lesions can not been resec ted only survived from 3 to 6 months with the mean of 4.2 months.No death occurred during the perioperative period. Conclusions For patients with type Ⅳ hilar cholangiocarcinoma， preoperative evaluation and tumor resection shall conducted so as to relieve obstruction of biliary tract，otherwise PTCD and PVE prior to the final lesion resection shall be performed.
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.
ObjectiveTo understand the latest progress of transcatheter arterial chemoembolization (TACE)-based combination therapies for unresectable liver metastasis from colorectal carcinoma, and to explore the safe and effective combination therapies in order to controlling the rapid progress of disease and improving the quality of life of patients. MethodsThe literatures about TACE-based combination therapies of liver metastasis from colorectal carcinoma and the latest advance in researches of this field at home and abroad were collected, and the application of combination therapies, the advantages and features of the combined treatments were reviewed. ResultsTACE was a safe and effective therapeutic modality in treating primary liver cancer or secondary liver cancer.Compared with a single treatment, TACE-based combination therapies had distinct advantages to patients with liver metastasis from colorectal carcinoma not only improved the quality of life but also prolonged the survival time.With the emerging of various kinds of new drugs and the rapid development of a variety of interventional treatments, it could bring long-term survival benifit for patients with liver metastasis from colorectal carcinoma. ConclusionsDoctors should pay attention to the combined treatments of patients with liver metastasis from colorectal carcinoma, improve the knowledge of personalized medication about advanced tumors and actively promote more usage of combination therapies.
ObjectiveTo summarize the progress and clinical application of portal vein embolization (PVE). MethodsDomestic and international publications about the PVE were retrieved and reviewed. ResultsPVE could effectively increase the perioperative security when selected at the appropriate time during liver resection surgery. However, there were some disputes on the best choice of the PVE in material, the use of dosage, and the clinical operation method. ConclusionsPVE as a method to induce liver to compensation, has a prominent role in increasing liver subtotal security, and improving the survival rate of patients. But it needs to be researched further to improve technique to promote future liver remnant hyperplasia compensatory faster and better.
ObjectiveTo explore the application of the technique of liver venous deprivation (LVD) for two-stage radical hepatectomy in patient with liver cancer underlying hepatitis B virus infection.MethodsA 53 years old patient diagnosed with central primary liver cancer (Ⅴ/Ⅷ segment) could not receive standard right hepatectomy since his future liver remnant was insufficient, so the LVD was performed to induce FLR growth. The general condition and CT scan were repeated at 1-, 2- and 3-week after LVD, the FLR and FLR weigh/ body weight ratio were calculated.ResultsThe FLR and FLR weight/body weight ratio before LVD were 24.2% and 0.459%, the FLR at 1-, 2- and 3-week after LVD were 29.5%, 38.3% and 44.4% respectively, the FLR weight/body weight were 0.545%, 0.707% and 0.820% at 1-, 2- and 3-week after LVD. The standard right hepatectomy was undertaken successfully at 25 days after LVD and discharged safely.ConclusionThe LVD technique could induce a rapid and large FLR volume and offer opportunity for patients with insufficient FLR to receive two-stage radical hepatectomy, is a novel method to induce FLR growth effectively.
