作者： Julien Hasselmann Tobias Kühme Jonas Bjork Stefan Acosta Vascular Center Skane University HospitalMalmoSweden Division of Occupational and Environmental Medicine Lund UniversityLundSweden

Background/Aims: Inguinal incisions are a common route of access in vascular surgery. Due to anatomical challenges and a diverse bacterial flora in this area, surgical site infections (SSI) represent a common, debilitating and sometimes life-threatening complication. The INVIPS-Trial evaluates the role of Negative Pressure Wound Therapy (NPWT) on closed inguinal incisions in elective vascular surgery to prevent SSI and other wound complications. Methods: This randomized controlled trial (RCT) registered at *** (Identifier: NCT01913132) compares the effects of a NPWT dressing (PICO, Smith & Nephew, UK) and the center’s standard wound dressing (Vitri Pad, ViTri Medical, Sweden) on postoperative wound complications, especially SSI. The study includes two distinct vascular procedures with different SSI risk profiles: endovascular aortic repair (EVAR) and open surgical approaches involving the common femoral artery (OPEN). Results: Four hundred ninety-five groin incisions in both treatment arms are anticipated to be included in the EVAR group and 147 inguinal incisions in both treatment arms in the OPEN group. Since a large percentage of inguinal vascular procedures in both groups but especially in the EVAR group are performed bilaterally, many patients can serve as their own control by randomly receiving NPWT on one and the standard dressing on the contralateral inguinal incision. Conclusions: This ongoing RCT attempts to elucidate the potential benefit of NPWT on closed inguinal incisions after different vascular procedures. Outcome and conclusions of this trial could have implications on postoperative wound care of patients in both vascular surgery and other surgical specialties.

比较历史分析是社会科学中的重要方法，以相对宏大的视角来比较历史案例，对国家等行为体进行因果解释，并且逐渐重视时间性和因果机制。早在马克思、托克维尔、密尔、韦伯等思想家的著作中早已蕴含了比较历史分析的思想，但是逐渐学科化和体系化则要到20世纪70年代之后。经历了三代理论的演进，比较历史分析的研究议题从“大历史、大过程、大比较”转向中短时间段比较，研究目标从追求普遍性解释到历史制度主义和机制性解释。比较历史研究的步骤包含了问题选取、变量选择与理论设计、因素分析与因果推断、案例比较与过程追踪、检视理论可能的推广性等主要步骤。随着方法和实证研究的完善，比较历史分析也逐渐趋于成熟，研究方法也从最初相对简单地应用密尔方法到进一步复杂化和精细化。比较历史分析为研究中国历史和当代发展提供了一种重要的视角，有助于从一个全球性的视角看待中国的变化。
