Objective To assess the effectiveness of an instructional DVD on the anatomy and repair of anal sphincter lacerations to improve postgraduate trainees’ understanding. Methods A total of 71 obstetrics and gynecology trainees completed a pretest of third‐ and fourth‐degree lacerations to assess baseline knowledge and perceptions. Question categories included anatomy, antibiotics, anesthesia, repair methods, complications, postoperative care, and risk factors. After 1 year of clinical experience, 67 trainees (94%) were randomly assigned into DVD (intervention) and non‐DVD (control) groups. A post‐test was administered 4 weeks later. Results In the DVD group (n = 34), mean scores on the pretest versus the post‐test were 65% vs 74% for postgraduate year (PGY)‐1 ( P = 0.09); 72% vs 83% for PGY‐2 ( P = 0.06); 67% vs 83% for PGY‐3 ( P = 0.01); and 75% vs 87% for PGY‐4 ( P < 0.001). In the non‐DVD group (n = 33), mean scores did not change significantly for any year level. The increase in score from pretest to post‐test was significantly different between the 2 groups, independent of year ( P < 0.001). DVD group scores improved significantly over non‐DVD group scores in anatomy ( P = 0.005) and repair methods ( P = 0.042) subscales. Conclusion An educational video is an effective tool for improving understanding of third‐ and fourth‐degree lacerations for physicians‐in‐training.
