背景和目的:减轻术后并发症是椎间融合成功的关键指标。与其他方法相比,LLIF与独特的并发症配置文件相关联,虽然许多研究试图报告术后并发症的发生率,目前对它们的定义或报告结构没有共识。这项研究的目的是标准化外侧腰椎椎间融合术(LLIF)特有的并发症的分类。材料和方法:采用搜索算法来识别所有描述LLIF后并发症的文章。然后使用改进的Delphi技术在七个国家的26名匿名专家之间进行了三轮共识。已发表的并发症被归类为主要并发症,未成年人,或非并发症使用60%的共识阈值。结果:共提取23篇文献,52描述与LLIF相关的个体并发症。在第一轮中,52个事件中有41个被确定为并发症,而7起被认为是与方法有关的事件。在第2轮中,将41例并发症共识事件中的36例分为主要或次要。在第3轮中,有52个事件中的49个最终被分为主要或次要并发症,并达成共识,虽然有三件事没有达成一致。血管损伤,长期的神经缺陷,并因各种病因返回手术室被确定为LLIF后的重要共识并发症.不愈合没有达到显著性,也没有被归类为并发症。结论:这些数据提供了第一个,LLIF后并发症的系统分类方案。这些发现可能会提高未来报告和分析LLIF后手术结果的一致性。
Background and Objectives: Mitigating post-operative complications is a key metric of success following interbody fusion. LLIF is associated with a unique complication profile when compared to other approaches, and while numerous studies have attempted to report the incidence of post-operative complications, there is currently no
consensus regarding their definitions or reporting structure. The aim of this study was to standardize the classification of complications specific to lateral lumbar interbody fusion (LLIF). Materials and Methods: A search algorithm was employed to identify all the articles that described complications following LLIF. A modified Delphi technique was then used to perform three rounds of
consensus among twenty-six anonymized experts across seven countries. Published complications were classified as major, minor, or non-complications using a 60% agreement threshold for
consensus. Results: A total of 23 articles were extracted, describing 52 individual complications associated with LLIF. In Round 1, forty-one of the fifty-two events were identified as a complication, while seven were considered to be approach-related occurrences. In Round 2, 36 of the 41 events with complication
consensus were classified as major or minor. In Round 3, forty-nine of the fifty-two events were ultimately classified into major or minor complications with
consensus, while three events remained without agreement. Vascular injuries, long-term neurologic deficits, and return to the operating room for various etiologies were identified as important consensus complications following LLIF. Non-union did not reach significance and was not classified as a complication. Conclusions: These data provide the first, systematic classification scheme of complications following LLIF. These findings may improve the consistency in the future reporting and analysis of surgical outcomes following LLIF.
