Four hundred and eighty two paients suffering from intrahepatic bile duct stone undergoing lobectomy and segmental resection (from 1975 to 1994,9) has reported. 63% of the patient in this group underwent 1-5 operations, including different types of biliary-intestinal anastomosis (21.6%). 482 cases underwent different types of hepatectomy, including left lateral-lobetomy 321 cases (66.6%),left hemihepatectomy 80 cases(16.6%), right hemihepatectomy 19 cases (3.9%), and multiple segmental resections 39 cases (8.1%, including Ⅴ+Ⅷ 11 cases, Ⅵ+Ⅶ 28 cases). Other type hepatectomy combined with guadrate lobectomy 20 cases (4.1%). Postoperative complication rate was 10.2%, including diliary fistula. hemobilia and subdiaphragmatic and resectional surface infectioin, 85% of the patients were followed up with an excellent result of 88%. The authors emphsize that hepatic lobectomy nad segmental resection is the core of treatment and selection of operative methods depends on clinical-patholigic types of the disease.
目的探讨肝内胆管结石合并肝胆管癌的临床诊断和治疗经验。 方法回顾性分析我院手术治疗28例肝内胆管结石合并肝胆管癌的病例资料。结果本组28例占同期肝内胆管结石病例的6.7%。术前各类影像学检查发现癌灶17例，5例获细胞学检查确诊。术中7例经快速组织活检证实。另4例系术后确诊。肿瘤多为腺癌，位于肝门胆管18例，肝内胆管9例，肝内、肝门部广泛浸润1例。根治性肿瘤切除8例，获随访6例，平均生存23个月； 姑息性肿瘤切除8例，获随访6例，平均生存11个月； 仅行外引流者7例，其中3例于术后2周内死亡，3例术后9个月内死亡，1例生存4个月后失访。结论长期肝内胆管结石刺激及继发感染是肝胆管癌发生的重要因素。联合应用影像学检查结合病理活检获得早期诊断和选择合理的根治性肝切除术是提高疗效的有效措施。
Twenty-one patients(male 18 cases,femal 3 cases)died of primary liver cancer after operation are reviewed.The liver tumors were located in the right lobe(13 cases),left lobe(3 cases),middle position of liver(4 cases)and hepatic hilum(1 cases).The average diameter of the tumors were 9.0cm.All the patients had suffered from liver cirrhosis and were operated on (most of them partial hepatectomy).The times of death were about 7 days,7-14 days later after operation.The data suggest that causes of death were different from the different stage after operation.The relations between partial hepatectomy and hepatic failure,and the liver cirrhosis and liver regeneration are discussed.

Objective To provide experimental evidence for the clinical application of ischemia therapy to treating pancreatic cancer. Methods After the model of pancreatic transplanted cancer was established in nude mice with orthotransplantation of human pancreatic cancer cell line into the pancreas, the ischemia of the right lobe of the pancreas was induced with ligation of the gastroduodenal, inferior pancreaticoduodenal and dorsal pancreatic arteries. Effects of regional ischemia on the growth of transplanted cancer and the pathomorphology of the transplanted cancer and pericancerous tissue were investigated. Results The transplanted cancer grew slower and its doubling time was longer in the ischemic group than in the control. On the 3rd, 7th and 14th day after operation, the size of transplanted cancer, the proliferative index and protein content of the cancer cells were significantly lower in the ischemic group than in the control (Ｐ＜0.01). Optical microscopy revealed large areas of coagulation necrosis, necrobiotic cells and the infiltration of inflammatory cells. The atrophy of acini, fibrosis and the infiltration of lymphocyte cells were found in pericancerous tissue. Conclusion Regional ischemia can destroy and inhibit the pancreatic transplanted cancer in nude mice effectively. The ischemia changes of pericancerous tissue may be unfavourable for the growth of the pancreatic transplanted cancer.
Objective To investigate the regulatory effect of somatostatin analogue (SMS201995,SMS) on proliferation and apoptosis in human cholangiocarcinoma cell line in vitro. MethodsProliferation curve, flow cytometry, agarose gel electrophoresis, Annexin VFITC and flow cytometric immunofluorescent technique were performed to identify the inhibitory effect on cell proliferation and the induction of apoptosis of human cholangiocarcinoma cells (SKChA1). ResultsSMS significantly reduced the SKChA1 cell growth by serum in long experiments and transiently accumulated it in G0/G1 phase. Dotplot analysis of cells duallabeled with Annexin VFITC and PI confirmed the induction of apoptosis by SMS in SKChA1 cells.AnnexinVFITC labeling was markedly enhanced following treatment with SMS for 24 h. DNA of treated SKChA1 cells appeared a ladder pattern characteristic of apoptosis. Besides, timedependent increase in bax and decrease in bcl2 occured during SMS treatment. Conclusion SMS could inhibit the proliferation activity and induce apoptosis of cholangiocarcinoma cell line SKChA1. The mechanisms of apoptosis might be correlated with the expression of apoptosisregulatory gene bax and bcl2.
Objective To investigate the expression of multigenes mediated by adenovirus in liver cancer cells and the effects on growth of cells transducted with multigenes. MethodsBy construction of recombinant adenovirus containing human p53, B7-1, GM-CSF, and IL-2 genes (Ad-multigenes), the expression level of target genes in three human hepatocellular carcinoma cell lines and a human hepatocellular cell line L02 was detected using ELISA, immunohistochemistry and FACS assay and the change of growth of these cells and the tumor cell apoptosis were observed. Results The human hepatic cells and liver cancer cells were all sensitive to adenovirus infection. At a MOI of 50 PFU/cell, among the cells examined nearly 90% were positive expression and except IL-2, other three genes were expressed with high efficiency. The growth of Ad-multigenes-transduced liver cancer cell lines was inhibited and apoptosis was induced, but the growth of Ad-multigenes-transduced normal hepatic cell line L02 did not change. Conclusion These results indicate that the adenovirus is an efficient vector for gene transfer into human liver cancer cells. These liver cancer cell lines transduced with multigenes constructed on one recombinant adenoviral vector can highly express target genes and their growth was inhibited, and apoptosis appeared.
