The interal changes of immunoglobulins in serum and bile among the rabbit models in partial biliary obstruction group (BO),partial biliary obstruction with infection group(BOI)and normal controls(Con)were studied. Concentrations of serum immunoglobulin A(IgA)in BO and BOI groups increase remarkably in all phases(Plt;0.001),Concentrations of serum IgG in both groups increase with the formation of gallstones. The IgG and IgA contents of bile samples in BO and BOI groups with negetive bacterial culture were much higher than that of the control group(Plt;0.05),but the Ig contents of bile with postive culture slightly lower than that of the control group.This experiment suggest in the formation of gallstones,the immunoglobulins of serum and bile had changed significantly.The Ig contents of bile have a relationship with the bacterial infection. Immunoglobulin A takes an important role in gallstone formation.
目的 对肝门胆管癌外科治疗疗效进行评价。 方法 回顾分析2007年3月－2012年3月收治的156例肝门胆管癌患者的临床资料。按手术方式将患者分为手术切除组（n=45）、胆道引流组（n=78）和姑息治疗组（n=33），并对住院期间并发症发生率、病死率及生存时间等进行分析。 结果 156例患者根治性切率为23.1%不同治疗方式住院期间病死率差异无统计学意义（P＜0.05）；手术治疗组与姑息治疗组并发症发生率差异有统计学意义（P＜0.05）。手术切除组、胆道引流组、姑息治疗组的1、3、5年累积生存率分别为64.4%、17.8%、0.0%；40.2%、12.6%、12.6%；17.7%、7.1%、0.0%，手术切除组生存情况明显好于其他两组（P＜0.05）。 结论 不建议所有患者术前均引流可减黄，且可以不过分强调R0切除。胆道引流可一定程度改善预后，但近远期胆道感染相关并发症发生率较高。
【Abstract】ObjectiveTo analyse the current situation and advance in perioperative therapy of liver transplantation for primary hepatocellular carcinoma(HCC).MethodsThe published papers on current situation and advance in the perioperative therapy of liver transplantation for HCC were reviewed.ResultsThe survival rate of liver transplantation for HCC in early stage has been the same as that for benign liver diseases up to now. However, it is still a difficult problem to improve the survival rate of liver transplantation for advanced HCC. The ideal perioperative therapies of liver transplantation for HCC should be helpful to suppress the growth of tumor while the HCC patients are waiting for donated livers, to diminish or eliminate the intraoperative spread or implantation of tumor cells and to repress the micrometastasis postoperatively. The current perioperative therapies of liver transplantation for HCC include hepatic arterial chemoembolization, systemic chemotherapy, radiotherapy, percutaneous ethanol injection into HCC and radiofrequency ablation etc. ConclusionThe perioperative assistant therapy of HCC can not only save time for patients before liver transplantation but also improve the survival rate after operation.
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.
31 cases of iatrogenic cholangic injury reported. 28 cases followed from 9 months to 6 years. iatrogenic cholangic injury is not an uncommon occurence main cases are inregular procedures, and carelessness in this group, only 9 cases were found intraoperatively. The main manifestations after injury were aggravating jaundice and/or bilious peritonitis. Symptoms, signs, B-type ultrsound and sometimes ERCP were used for diagnosis. Once the injury ascertained ends are the best treatment, an alternative Roux-Y Cholangiojejunostomy was also commonly used. In this group, 4 cases received the first methos and all with good results; 23 patients treated by the second methos, 17 were uneventful, 4 experienced more or less abdomenal pain, 2 suffered difinite repeated cholangitis and another 1 died.
