This video demonstrates surgical knot tying, as an introduction to basic surgical practice. Innovative introduction to surgery in the preclinical years. A surgical skills elective to expose preclinical medical students to surgery. Sammann A, Tendick F, Ward D, Zaid H, O'Sullivan P, Ascher N. Surgical and procedural skills training at medical school - a national review. We modified it for SILS so that it has a locking mechanism caused by knot deformation. ![]() The clinch knot is a kind of slipknot that has been historically used by fishermen. ĭavis CR, Toll EC, Bates AS, Cole MD, Smith FCT. For example, sliding resistance may be encountered when tying knots for a Zshaped suture, and it could damage the sutured tissue.

The addition of a Web-based expert instructional video to a standard curriculum, coupled with knot board practice, appears to have a positive impact on medical student knot-tying proficiency. Increased knot board practice was significantly correlated with higher postclerkship scores on the knot-tying task, but only in the video group (r=.47, P<.05). Postclerkship scores improved in both the nonvideo and video groups (mean 28.4, SD 5.4, P<.001 and mean 28.7, SD 6.5, P=.004, respectively). At the completion of the clerkship, students were again videotaped and evaluated.Īt initial evaluation, preclerkship cumulative scores (range 0-36) on the standard checklist and anchored scale were not significantly different between the nonvideo and video groups (mean 20.3, SD 7.1 vs mean 20.2, SD 9.2, P=.90, respectively). The video group was provided unlimited access to an expert knot-tying instructional video. Students were then randomized to either (1) expert video (n=26) or (2) nonvideo (n=24) groups. Two blinded female pelvic medicine and reconstructive surgery physicians evaluated proficiency with a standard checklist (score range 0-16) and anchored scoring scale (range 0-20) higher numbers represent better skill. The aim of this study was to determine whether viewing a Web-based expert knot-tying training video, in addition to the standard third-year medical student curriculum, will result in more proficient surgical knot tying.Īt the start of their obstetrics and gynecology clerkship, 45 students were videotaped tying surgical knots for 2 minutes using a board model. Many senior medical students lack simple surgical and procedural skills such as knot tying. ![]()
