BACKGROUND
This study aimed to compare the effectiveness of Halsted's method "see one, do one, and teach one" with Peyton's Four-Step Approach for teaching intracorporal suturing and knot tying (ICKT).
METHODS
Laparoscopically naïve medical students (n = 60) were randomized to teaching of ICKT with either Halsted's (n = 30) or Peyton's method (n = 30) for 60 minutes. Each student's first 3 and final sutures were evaluated using Objective Structured Assessment of Technical Skills (OSATS), procedural implementation, knot quality, total time, and suture placement accuracy.
RESULTS
Performance score and OSATS-PSC always differed significantly in favor of Peyton's group (p = 0.001). OSATS-GRS (p = 0.01) and task time (p = 0.03) differed only in the summary of the first 3 sutures in favor of Peyton's group. There were no significant intergroup differences in knot quality and accuracy.
CONCLUSIONS
Peyton's Four-Step Approach is the preferable method for learning complex laparoscopic skills like ICKT.
背景
本研究旨在比较霍尔斯特德“看一个，做一个，教一个”方法与佩顿四步法在体内缝合和打结教学中的有效性。
方法
将初次接触腹腔镜手术的医学生（n = 60）随机分为两组，分别采用霍尔斯特德方法（n = 30）或佩顿方法（n = 30）进行60分钟的体内缝合和打结教学。使用客观结构化技术技能评估（OSATS）、操作实施、打结质量、总时间和缝合位置准确性对每位学生的前3针和最后一针进行评估。
结果
佩顿组的表现得分和OSATS-PSC始终显著更高（p = 0.001）。仅在前3针缝合的总结中，OSATS-GRS（p = 0.01）和任务时间（p = 0.03）在佩顿组更具优势。两组在打结质量和准确性方面无显著差异。
结论
佩顿四步法是学习如体内缝合和打结等复杂腹腔镜技能的更优方法。
