Abstract：
There is an ongoing debate whether a surgical drainage is beneficial to prevent local accumulation of hematoma and to reduce the rate of wound infections, and neurological deficits. Data from the German Spine Society (DWG) registry were filtered for surgically treated spine tumor cases between 2017 and 2021. Cases were categorized into with (Group I) and without (Group II) placement of a surgical drainage. Subgroups were compared for demographic data, type of surgery, experience of the surgeon and postoperative surgical complications. 10,029 cases were included into final analysis (Group I: 3007; Group II: 7022). There was no significant difference between both groups regarding age or gender distribution. Average morbidity of patients was significantly elevated in Group I (p < 0.05) and the rates of invasive surgery were significantly increased in this group (p < 0.001). Overall complication rates were reported with 12.0% (Group I) and 8.5% (Group II). There were significantly more epidural hematoma (p < 0.001) and motor dysfunction (p = 0.049) as well as deep wound infections (p < 0.001) and implant failures (p = 0.02) in Group I. A surgical wound drainage cannot prevent epidural hematoma.
摘要：
目前仍在争论外科引流是否有利于防止血肿局部积聚和降低伤口感染率。和神经缺陷。来自德国脊柱协会（DWG）注册的数据在2017年至2021年之间被过滤为手术治疗的脊柱肿瘤病例。病例分为（I组）和未（II组）外科引流。比较亚组的人口统计数据，手术类型,手术经验及术后并发症。最终分析包括10,029例（第一组：3007；第二组：7022）。两组之间在年龄或性别分布方面没有显着差异。I组患者的平均发病率显着升高（p<0.05），而侵入性手术的发生率显着升高（p<0.001）。总体并发症发生率分别为12.0%（I组）和8.5%（II组）。I组硬膜外血肿（p<0.001）和运动功能障碍（p=0.049）以及深部伤口感染（p<0.001）和植入物失败（p=0.02）明显增多。手术伤口引流不能预防硬膜外血肿。
