The initial approach of two sides hypogastric artery ligation and isolation with laparoscope before excision of presacral tumor

To observe the significance of excision of presacral tumor after two sides hypogastric artery ligation and tissue dissociation with laparoscope. Twenty-one patients with sacral tumor were performed excision of presacral tumor after two sides hypogastric artery ligation and tissue dissociation with laparoscope. All sacral tumor were removed successfully, the mean volume of operative blood was 800 ml (range 500-1900 ml), and all the patients were followed up 3-25 months, averaged time 11 months. One patient was recurred after 2 months of operation (the patient was Ewing's sarcoma, and refused to accept radiotherapy and chemotherapy after operation), 1 patents died of brain metastases after 9 months of operations. There were no recurrence in the others patients. The excision of presacral tumor after two sides hypogastric artery ligation and tissue dissociation with laparoscope is an effective operation method, with the advantages of decreasing the operative blood and difficulty of sacral tumor excision, and dimi
