Experience of radical surgical treatment in 253 patients with hepatic echinococcosis is presented. Twenty-six patients underwent hepatic resection; 218, pericystectomy, 9 patients, combined interventions. Based on comparative analysis of the results of surgical treatment in 109 patients from the study and control groups, it is concluded that radical operations have significant advantages and show fever postoperative complications and recurrences. Removal of fibrous capsule is a token of successful treatment for hepatic echinococcosis. 相似文献

The nearest outcomes of 305 pancreatoduodenal resections (PDR) for malignant and benign diseases of the pancreas head and periampullar zone are presented. Necessity of differential approach to choice of method of pancreatodigestive anastomosis formation is demonstrated. In unectatic main duct of the pancreas and unchanged pancreatic parenchyma there is a high risk of postoperative pancreatitis and lethal outcome which achieved 29.8% in the group of 57 patients. In patients with diameter of main pancreatic duct more than 3 mm and fibrotic changes of its parenchyma, the majority of methods of pancreas inclusion the in digestive canal were characterized by favorable results, lethality was 7.7% among 248 patients. Recently, the increase of rate of PDR with pylorus preservation permits to apply widely pancreato-, bilio-, and duodenoenteroanastomosis on the same jejunal loop. 相似文献

Restoration of thrombolytic potential in plasminogen-deficient mice by bolus administration of plasminogen 总被引:4,自引:0,他引:4
Homozygous plasminogen-deficient (Plg-/-) mice had a significantly reduced thrombolytic capacity toward intravenously injected 125I-fibrin labeled plasma clots prepared from Plg-/- murine plasma (9% +/- 3% lysis after 8 hours; (mean +/- SEM, n = 6), as compared with 82% +/- 8% in wild-type mice; P < .0001). Bolus injection of 1 mg purified murine plasminogen in 10- to 17-week-old Plg-/- mice increased the plasminogen antigen and activity levels at 8 hours to normal levels (130 +/- 5 micrograms/mL). Plasminogen administration was associated with significant restoration of thrombolytic potential (64% +/- 7% spontaneous clot lysis; P < .0001 versus lysis without plasminogen injection). Bolus injection of 1 mg plasminogen in homozygous tissue- type plasminogen activator-deficient (t-PA-/-) mice doubled the plasminogen antigen and activity levels after 8 hours and increased 125I-fibrin clot lysis at 8 hours from 13% +/- 3% to 34% +/- 5% (P = .008). Fibrinogen, t-PA antigen and alpha 2-antiplasmin activity levels after 8 hours were not significantly different in the groups with or without plasminogen injection. Injection of plasminogen induced a variable increase (on average 7- to 10-fold) of PAI-1, but no correlation with the extent of spontaneous clot lysis was observed. Histopathologic examination at the end of the experiments revealed that fibrin deposition in the liver of Plg-/- mice was slightly reduced 8 hours after bolus plasminogen injection (P = .007) and markedly reduced after 24 hours (P < .0001). Plasminogen antigen levels in liver extracts were comparable with those found in wild-type mice at 8 hours (130 +/- 20 versus 110 +/- 15 ng/mg protein) and decreased to 25 +/- 3.2 ng/mg protein at 24 hours. Thus, restoration of normal plasminogen levels in Plg-/- mice normalized the thrombolytic potential toward experimentally induced pulmonary emboli, and resulted in removal of endogenous fibrin deposits within 24 hours. 相似文献
