Résumé
Objective To evaluate the effectiveness of enucleation for the treatment of huge hemangiomas. Methods From 1979 to 1998, enucleation was used for the treatment of hepatic cavernous hemangiomas in 126 patients, among them 18 with multiple tumors and 6 with centrally located lesions. For the tumors larger than 10 cm in diametre or located in theⅠ or Ⅷ segment of the liver, enucleation combined with intermittent inflow vascular occlusion was adopted. Results All cavernous hemangiomas in this group were enucleated successfully, there was no mortality. The median intraoperative blood loss was 1015?577*!ml(200*!ml～4*!500*!ml). Postoperative complications developed in 15 patients including pleural effusion in 10 and wound infection in 5. 54 patients were lost from follow up. None of the remaining 72 patients had recurrence at the follow up ranging from 6 months to 18 years and 4 months. Conclusion Enucleation of cavernous hemangioma of the liver is a safe and effective alternative to hepatectomy.
Résumé
In this experiment we used the model of the orthotopic liver transplantation with three cuff technique in rats.In treated group,coenzyme Q_(10) was injected intravenously into donor rats before donor hepatectomy.At the 4th hour after transplant,the activity of superoxide dismu- tase (SOD) and the level of lipid peroxidation (LPO) both in the blood and in the liver tissue were measured,meanwhile,the specimens of the grafted liver tissue were sent for microscope and elec- tromicroscope studies.The results showed:(1) The activity of SOD in treated group were higher than that in control group (P
