两种环锯脊柱骨组织活检的比较△

Trephines with or without inner thread for spinal bony tissue biopsy

摘要:

[目的] 探讨两种环锯在脊柱骨组织活检中的应用效果。[方法] 回顾性分析2020 年1 月—2023 年8 月96 例脊柱骨组织活检患者的临床资料，根据术前医患沟通结果，50 例采用内螺纹环锯活检（内螺纹组），另外46 例采用普通环锯活检（普通组）。比较两组患者围手术期相关指标、检测结果及术后不良反应。[结果] 两组活检节段、切口长度、术中出血量、活检成功率的差异均无统计学意义（P＞0.05），内螺纹组手术时间[(17.0±2.8) min vs (19.5±3.0) min, P＜0.001] 显著少于普通组、获取组织阳性率显著高于普通组（87.8% vs 64.5%, P＜0.001）、术后并发症的总发生率显著低于普通组（20.0% vs 54.4%, P＜0.001）。[结论] 使用内螺纹环锯可明显缩短椎体活检时间，提高穿刺活检阳性率，降低术后并发症发生率。

Abstract:

[Objective] To compare the efficiency of trephines with or without inner thread for spinal bony tissue biopsy. [Methods] Aretrospective study was conducted on 96 patients who underwent spinal bony tissue biopsy from January 2020 to August 2023. Based on pre-operative surgeon-patient discussion, 50 patients had biopsy performed by trephine with inner thread (the IT group), while the remaining 46patients were by trephine of non-IT ( the non-IT group). The perioperative items, test results and postoperative adverse reactions were com-pared between the two groups. [Results] Although there were no significant differences in biopsy segment, incision length, intraoperativeblood loss and biopsy success rate between the two groups (P＞0.05), the IT group proved significantly superior to the non-IT group in termsof operative time [(17.0±2.8) min vs (19.5±3.0) min, P＜0.001], and the positive rate of tissue harvesting (87.8% vs 64.5%, P＜0.001), in addi-tion, the former was significantly better than the latter regarding to the overall incidence of postoperative complications (20.0% vs 54.4%, P＜0.001). [Conclusion] Using the trephine with inner thread does significantly shorten the spine biopsy time, increase the positive rate of punc-ture biopsy, and reduce the incidence of postoperative complications.
