目的：缝合是一项重要的核心手术能力，需要持续练习。本研究的目的是评估在资源有限的环境下香蕉作为练习缝合技术的一种介质的情况。
材料和方法：采用交叉设计，20名卢旺达大学的医学生在香蕉皮和商业泡沫板上练习缝合。学生被随机分为两组：A组先在泡沫板上练习，然后在香蕉上练习；B组先在香蕉皮上练习，然后在泡沫板上练习。之后对学生进行一次课后调查，以评估他们对香蕉皮作为缝合练习材料的态度。由三名接受过专科培训的面部整形外科医生根据缝合间距均匀、结的位置、结的合适度、无空气结以及咬合力合适等标准对每个学生的缝合表现进行评分。
结果：由面部整形外科医生评分的缝合表现表明，在56.7%的情况下，用香蕉进行缝合的效果与泡沫相当或更优。20名学生参加了该研习班；16名学生回复了调查（回复率 = 80%）。学生们在香蕉皮上练习缝合时感觉舒适（中位数 = 4，四分位距 = 1），并且非常同意在香蕉皮上缝合是一项有用的活动（中位数 = 5，四分位距 = 1）。学生们认为香蕉皮和泡沫是可比较的学习平台（中位数 = 3.5，四分位距 = 1），并且觉得他们在香蕉皮上练习后缝合能力有所提高（中位数 = 4，四分位距 = 1.3）。
结论：香蕉皮是一种低成本且与合成缝合介质同样可行的替代品。
Purpose: Suturing is an important core surgical competency that requires continued practice. The purpose of this study was to evaluate bananas as a medium for practicing suture techniques in resource-limited settings.Materials and methods: Using a crossover design, 20 University of Rwanda medical students practiced suturing on banana peels and commercial foam boards. Students were randomized into 2 groups: group A practiced on foam boards first and then bananas, and group B practiced on banana peels first and then foam boards. A post-workshop survey was then administered to students to gauge their attitude towards banana peels as a suturing practice material. Suture performance for each student was graded by three fellowship-trained facial plastic surgeons based on consistent spacing, knot location, appropriate knot, absence of air knots, and adequate bite size.Results: Suture performance graded by facial plastic surgeons demonstrated that suturing outcomes with bananas were equal or superior to foam in 56.7% of instances. Twenty students participated in the workshop; 16 students responded to the survey (response rate = 80%). Students were comfortable practicing suturing with banana peels (Mdn = 4, IQR = 1) and strongly agreed that suturing banana peels was a useful activity (Mdn = 5, IQR = 1). Students thought banana peels and foam were comparable learning platforms (Mdn = 3.5, IQR = 1) and felt their suturing abilities improved with practice on banana peels (Mdn = 4, IQR = 1.3).Conclusions: Banana peels are a low cost, equally viable alternative to synthetic suture media.
