美国圣迭戈加利福尼亚大学的麻醉学教授Jordan Katz根据对37例病人进行研究的结果认为,经蝶窦的化学性切除垂体可使扩散性肿瘤患者经其它方法不能处理的严重性疼痛得以缓解。 Katz在科罗拉多疼痛学会的一次会议上报告,他是在一些早期的研究后谨慎地进行化学性切除垂体,结果表明此举能有效地控制对大剂量麻醉剂治疗无效的晚期病变的弥散性疼痛。 Jordan Katz, Professor of Anesthesiology at the University of California, San Diego, USA, according to a study of 37 patients, concluded that transsphenoidal chemically resecting the pituitary gland relieves severe pain in patients with diffuse tumors that cannot be treated by other methods. Katz reported at a meeting of the Colorado Association of Pain that he had carefully performed chemically resected pituitary after some early studies. The results suggest that this can effectively control diffuse pain in late lesions that are ineffective for large-dose anesthetics.
