Thermography can be used in pre-operative planning of free perforator flap surgeries. Thermography assesses skin temperature by measuring the quantity of infrared radiation observed. In this meta-analysis, authors assess the sensitivity of smartphone-based thermal imaging (SBTI) in the detection of perforators and analyze the difference between static and dynamic imaging.
Authors followed the PRISMA guidelines for systematic reviews and meta-analyses. The meta package in R was used to conduct the meta-analysis. The "metaprop" function was used to calculate the overall sensitivity estimate and 95% confidence interval. The "metaprop.one" function was used to calculate subgroup estimates for static and dynamic study types. The "metareg" function was used to conduct meta-regression analyses to explore sources of heterogeneity.
This study includes seven articles with 1429 perforators being evaluated. The overall proportion of the sensitivities was estimated to be 0.8754 (95% CI: 0.7542; 0.9414) using a random effects model. The heterogeneity of the studies was high, as indicated by the tau^2 value of 1.2500 (95% CI: 0.4497; 8.4060) and the I^2 value of 92.6% (95% CI: 88.1%; 95.4%). The pooled sensitivity for static imaging was 0.8636 (95%CI: 0.6238-0.9603) with a tau^2 of 2.0661 and a tau of 1.4374, while the pooled sensitivity for dynamic imaging was slightly higher (p = 0.7016) at 0.8993 (95%CI: 0.7412-0.9653) with a smaller tau^2 of 0.8403 and a tau of 0.9167.
Further studies need to confirm that SBTI is a reliable and convenient technique for detecting perforators for the pre-operative planning of free perforator flap surgeries.
热成像可用于游离穿支皮瓣手术的术前规划。热成像通过测量观察到的红外辐射量来评估皮肤温度。在这项荟萃分析中，作者评估了基于智能手机的热成像（SBTI）在检测穿支方面的敏感性，并分析了静态成像和动态成像之间的差异。
作者遵循PRISMA系统评价和荟萃分析指南。使用R语言中的meta包进行荟萃分析。“metaprop”函数用于计算总体敏感性估计值和95%置信区间。“metaprop.one”函数用于计算静态和动态研究类型的亚组估计值。“metareg”函数用于进行meta回归分析以探索异质性来源。
本研究纳入7篇文章，共评估1429个穿支。采用随机效应模型估计敏感性的总体比例为0.8754（95%CI：0.7542；0.9414）。tau^2值为1.2500（95%CI：0.4497；8.4060），I^2值为92.6%（95%CI：88.1%；95.4%），表明研究的异质性较高。静态成像的合并敏感性为0.8636（95%CI：0.6238 - 0.9603），tau^2为2.0661，tau为1.4374，而动态成像的合并敏感性略高（p = 0.7016），为0.8993（95%CI：0.7412 - 0.9653），tau^2较小，为0.8403，tau为0.9167。
需要进一步研究以证实SBTI是一种用于游离穿支皮瓣手术术前规划中检测穿支的可靠且便捷的技术。
