Abstract

Background: Medical students often experience difficulty comprehending anatomic relationships of complex operations to which they are exposed during surgical clerkship. Pancreaticoduodenectomy, the Whipple procedure, is one such operation. Although video recordings are available to facilitate the learning of the Whipple procedure, commercially available tapes are not self-explanatory to the uninitiated. Since we have previously demonstrated that third-year medical students could learn the operative steps of inguinal herniorraphy by a paper-cutting exercise, we set out to determine whether an exercise of similar design could enhance a student’s comprehension of the Whipple procedure. Methods: Using Adobe Illustrator 5.5 for MacIntosh, an exercise was developed on a 8.5 × 11- inch paper that could be distributed to students for self-administration. The exercise was performed using a #15 scalpel or an iris scissors. Thirty-seven students were randomized into two groups. Each student received a pretest of questions focusing on the Whipple procedure. Group I was shown an 18-minute commercially available teaching video on the Whipple procedure. Group II was given the Whipple origami exercise, which required 20 minutes to complete. A first posttest was administered to each group. Next, the groups switched exercises, and a second posttest was administered. Results: There was no significant difference between the groups’ pretest scores (two-tailed t test, P = 0.290). Group I improved its score from an average of 64.21 (SD 14.27) to 67.89 (SD 13.16) after watching the video, and further to 77.89 (SD 14.37) after completing the paper-cut exercise. Group II improved from 60.00 (SD 9.43) to 78.95 (SD 11.00) after performing the paper-cut, but derived no additional measurable benefit from watching the video, average score 74.74 (SD 18.37). After the first exercise, students who performed the paper-cut showed a significantly greater improvement in test scores compared with students who saw the video ( P = 0.0035 by Mann-Whitney U). After both groups had completed the exercises, the mean changes from baseline were no longer significantly different ( P = 0.58 by Mann-Whitney U). Conclusion: As a single educational intervention, the paper-cut exercise was a more effective teaching device than the video in the given time frame. The origami model may be generalized to a variety of surgical procedures and appears to be a valuable adjunct to traditional teaching.
