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.
【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.
ObjectiveTo summarize the surgical technique and indications for liver masses involving the second and the third porta hepatis.MethodsThirteen cases of liver mass involving the second and the third porta hepatis, who underwent surgery in West China Hospital of Sichuan University from June 2013 to September 2016 were collected retrospectively, then made a statistical analysis, including patients’ information, characteristics of liver masses, operation information, and result of followed-up.ResultsOf the 13 cases, there were 3 cases of hepatic alveolar echinococcosis, 4 cases of hepatocellular carcinoma, 4 cases of intrahepatic cholangiocarcinoma, and 2 cases of liver metastasis induced by colon cancer. The mean tumor diameter was 12.5 cm (7–21 cm). Preoperative imaging examinations showed that mass had involved the second and the third porta hepatis, and all masses were resected by surgery without perioperative death, including 7 cases of right three hepatectomy resection, 1 case of left three hepatectomy resection, 4 cases of right hepatectomy resection, and 1 case of left hemi hepatectomy resection; among them, 9 cases were performed caudal lobectomy resection. The mean of operative time was 313 min (210–450 min), the mean of intraoperative blood loss was 592 mL (300–1 100 mL). Four cases received blood transfusion with 300–450 mL (mean of 338 mL). The total hepatic blood inflow occlusion time was 25–55 min (mean of 42 min). Five cases received venous reconstruction, and 1 case received hepatic vein reconstruction. After operation, ascites occurred in 6 cases, pleural effusion occurred in 6 cases, liver failure occurred in 2 cases, bile leakage occurred in 2 cases, pulmonary infection occurred in 3 cases, deep vein thrombosis occurred in 1 case. All of the 13 cases were followed-up for 1–39 months (median time was 14 months), during the followed-up period, 4 cases died, including 3 cases of intrahepatic cholangiocarcinoma and 1 case of liver metastasis induced by colon cancer.ConclusionIt is encouraging to apply the vascular reconstruction and skilled hepatic partition technique for resection lesions which involved the second and the third porta hepatis, through meticulous preoperative evaluation and preparation.
Objective To discuss the therapeutic effectiveness of surgical approach to complex intrahepatolithiasis with biliary liver cirrhosis.Methods A case of complex intrahepatolithiasis with biliary liver cirrohosis, portal hypertension was treated with splenectomy and pericardial devascularization plus left hepatectomy and portal cholangio plasty with T tube drainage. Results Follow up one year and a half after operation, no symptom of cholangitis was found, and there is no relapse up to date. Conclusion Combined operation of hepatectomy with splenectomy is an ideal and effective treatment for complex intrahepatolithiasis with biliary liver cirrhosis.
ObjectiveTo evaluate efficacy and safety of laparoscopic Glissonean pedicle transection anatomic hepatectomy using indocyanine green (ICG) fluorescence imaging.MethodThe retrospective analysis was made on the preoperative clinical data, surgical treatment and postoperative status of a patient with hepatocellular carcinoma who underwent the laparoscopic Glissonean pedicle transection anatomic hepatectomy using the ICG fluorescence imaging technology in the Department of Liver Surgery, West China Hospital of Sichuan University.ResultsAccording to the preoperative history, imaging and laboratory examinations, the diagnosis of hepatocellular carcinoma was considered. The intraoperative exploration revealed that there was only one tumor located in the segment Ⅳ and was superficial. The ICG fluorescence imaging was used to perform the Glissonean pedicle transection anatomic hepatectomy. The postoperative pathological diagnosis was consistent with hepatocellular carcinoma without serious complications. The patient recovered well. No recurrence was found in the follow-up period up to 6 months.ConclusionsLaparoscopic Glissonean pedicle transection anatomic hepatectomy using ICG fluorescence technology can be used as a safe and precise treatment to solve problems such as bleeding during operation, difficult determination of tumor boundary, and whether having residual tumor in surgical margin.
