经皮骨成形术治疗椎体外恶性溶骨性病变的疗效分析

Effelt analysis of percutaneous osteoplasty for the treatment of malignant osteolytic lesions outside the vertebrae

目的探讨经皮骨成形术(POP)治疗椎体外恶性溶骨性病变的临床疗效及安全性。方法2005年4月至2007年12月,11例椎体外恶性溶骨性病变患者作经皮骨成形术。对于术前未明确病变性质者,骨成形术前先给予活检。术后随访至少6个月。使用简明疼痛问卷表(BPI)对临床疗效进行评估。使用SAS6.12进行统计分析。结果11患者均顺利完成手术,技术成功率100%。3例患者出现骨水泥外溢,未出现严重临床并发症。术前及术后2周BPI评价显示患者疼痛明显缓解(P<0.05),疼痛影响的日常活动、情绪、行走、睡眠、生活乐趣等方面均有改善(P<0.05),工作、社交方面改变不明显(P>0.05)。结论POP治疗椎体外恶性溶骨性病变安全、有效,值得临床推广应用。

Objective To assess the clinical efficacy and safety of percutaneous osteoplasty (POP) in treating malignant osteolytic lesions outside the vertebrae. Methods From Jan. 2005 to Dec. 2008, POP was performed in 11 patients with malignant osteolytic lesions outside the vertebrae. Biopsy was carried out before POP when the lesion's pathology was undefined. A follow-up was made for at least 6 months. Brief Pain Inventory (BPI) was used to evaluate the clinical efficacy, and a statistic analysis was made with the help of software SAS 6.12. Results POPs were successfully performed in all 11 patients, with the technical successful rate of 100%. Cement leakage was found in 3 patients, but did not cause serious complications. Obvious pain relief was revealed clinically with a significant difference in BPI before and after POP (P 0.05). Patients also showed a definite improvement in their daily activities that had been influenced by pain, such as walking, sleeping, recreation, as well as in their spirit feeling and emotion (P 0.05), although no marked favourable change was seen in their work and social activities (P 0.05). Conclusion POP is an effective and safe technique in treating malignant osteolytic lesions outside the vertebrae.
