: There is evidence from various surgical specialties that incisional negative pressure wound therapy (iNPWT) might reduce postoperative surgical site infections (SSIs). In visceral and general surgery, there is varying evidence of its efficacy in reducing surgical site infections.: A prospectively registered patient cohort of 43 patients with abdominal wall and visceral surgery received treatment with iNPWT and was compared to a matched retrospective cohort to analyze its effects on SSI occurrence and respective risk factors. Groups were matched by procedure, sex, body mass index and age. We used two different systems of iNPWT: (i) PREVENA or (ii) self-made epicutaneous iNPWT from common VAC material.: We could not find a total reduction in postoperative SSIs by application of iNPWT. But within the iNPWT cohort, patients with self-made iNPWT suffered more often from SSIs compared to the commercial iNPWT subgroup. No patient specific risk factors could be identified to advocate the use of iNPWT.: Our data do not support the use of an incisional negative pressure wound therapy on closed wounds in midline laparotomy incisions. Although, differences exist between the commmercial and self-made systems.
有来自多个外科专业的证据表明，切口负压伤口治疗（iNPWT）可能减少术后手术部位感染（SSI）。在腹部和普通外科手术中，其在减少手术部位感染方面的疗效证据不一。
对 43 例接受腹壁和内脏手术的患者进行了前瞻性登记的患者队列接受了 iNPWT 治疗，并与匹配的回顾性队列进行了比较，以分析其对 SSI 发生和各自危险因素的影响。组间通过手术、性别、体重指数和年龄进行匹配。我们使用了两种不同的 iNPWT 系统：（i）PREVENA 或（ii）从普通 VAC 材料自制的经皮 iNPWT。
我们没有发现应用 iNPWT 可降低术后 SSI 的总发生率。但在 iNPWT 组中，与商业 iNPWT 亚组相比，使用自制 iNPWT 的患者更常发生 SSI。没有确定任何患者特定的危险因素来支持使用 iNPWT。
我们的数据不支持在中线剖腹切口的闭合伤口上使用切口负压伤口治疗。尽管商业和自制系统之间存在差异。
