Objective: Given limitations in surgical educational resources, more efficient teaching methods are needed. We sought to evaluate 3 strategies for improving skills in subcuticular suturing-practice with an instructional video, practice with expert instructor supervision, and independent practice.
Design: Fifty-eight medical students volunteered for this research. Students viewed a video on subcuticular suturing then completed a pretest requiring closure of an incision in a plastic model. Students were randomized among 3 groups: practice with an instructional video (group A), practice with supervision by an expert instructor (group B), and independent practice (group C). After instruction, students completed a posttest, then a retention test 1 week later. Their performances were video recorded and evaluated using a validated scoring instrument composed of global and task-specific subscales.
Results: Performances measured using both subscales improved significantly from pretest to post-test only for group B. However, when comparing student performances between pretest and retention posttest, significant improvements on both subscales were seen only in group A.
Conclusion: These results suggest that practice with an instructional video is an effective method for acquiring skill in subcuticular suturing.

Introduction Cosmetic surgery has advanced significantly, with wound closure techniques crucial for determining aesthetic and healing outcomes. Recently, cyanoacrylate glue and subcuticular sutures have gained attention for their unique benefits in cosmetic procedures. Cyanoacrylate glue, a non-invasive tissue adhesive, facilitates faster wound closure with minimal trauma, while subcuticular sutures offer durable, concealed closures, particularly suited for areas under mechanical stress.

Purpose: Use of video-based education (VBE) to teach surgical skills has increased rapidly and been shown to accelerate students' and residents' time to satisfactory skill acquisition while also improving trainees' satisfaction. However, its implementation is limited by logistical factors such as: video quality, view obstruction, and excessive motion. We aim to study the feasibility of using VBE to teach medical students basic suturing skills.

Objective: Wound complications are one of the major sources of morbidity after open vascular procedures, especially lower extremity bypass (LEB). The preferred skin closure method is based on surgeon preference. Because no data clearly demonstrates the superiority of one method over the other, we aimed to compare outcomes of staples vs sutures for skin closure after LEB.
