To estimate the efficacy of viewing an educational video in the acquisition of laparoscopic suturing skills.
A prospective observational study (Canadian Task Force classification II-2).
Tertiary care academic medical institution.
Twelve candidates interviewing for the female pelvic medicine and reconstructive surgery fellowship position at our institution.
Candidates were evaluated in the laparoscopy laboratory before and after watching a 6-minute educational video on the basic principles of laparoscopic suturing. Each candidate evaluation included the following tasks: (1) introduction of a needle through a trocar (timed in seconds); (2) load and position a needle for suturing with a laparoscopic needle holder (evaluated by number of movements); (3) running continuous suture with 2 passes (timed in seconds); (4) intracorporeal knot tying with 2 throws (timed in seconds); and (5) extracorporeal knot tying with 2 knots (timed in seconds).
Wilcoxon signed rank test was used for the statistical comparison of the candidates' performance before and after viewing the video. After viewing the teaching video, the total median time to perform all timed tasks improved by 20% (115.5 seconds, p = .009). Significant improvement occurred in the median time of introducing the needle through a trocar, continuous suturing, and extracorporeal knot tying (p = .02, p = .01, and p = .003, respectively).
The use of an educational video appears to be an effective method for the acquisition of basic laparoscopic suturing skills.
评估观看教育视频在获取腹腔镜缝合技能方面的效果。
前瞻性观察研究(加拿大工作组分类II - 2)。
三级医疗学术医疗机构。
十二名在我们机构参加女性盆底医学与重建外科 fellowship 职位面试的候选人。
候选人在观看一段关于腹腔镜缝合基本原则的6分钟教育视频前后,在腹腔镜实验室接受评估。每位候选人的评估包括以下任务:(1)将针穿过套管针(以秒计时);(2)用腹腔镜持针器装载并定位针以便缝合(按动作次数评估);(3)连续缝合2针(以秒计时);(4)体内打结2次(以秒计时);(5)体外打结2个(以秒计时)。
采用 Wilcoxon 符号秩检验对候选人观看视频前后的表现进行统计学比较。观看教学视频后,完成所有计时任务的总中位时间缩短了20%(115.5秒,p = .009)。将针穿过套管针、连续缝合和体外打结的中位时间有显著改善(分别为p = .02、p = .01和p = .003)。
使用教育视频似乎是获取基本腹腔镜缝合技能的有效方法。
