The performance paradox: selection bias in surgical video presentations and its impact on clinical reality
摘要
Surgical video presentations at international congresses are essential for global knowledge sharing, yet they overwhelmingly favor polished, best-case scenarios instead of reflecting routine clinical practice. This perspective examines the selection bias embedded in surgical educational media, a phenomenon we term the “Performance Paradox.” Such selective curation distorts perceptions of procedural complexity, risk, and expected outcomes, ultimately hindering genuine surgical education and compromising scientific transparency. This bias represents a surgical manifestation of the broader positive outcome bias, or “file-drawer problem.” By omitting videos that include complications, unanticipated technical challenges, or even average results, educators unintentionally promote unrealistic expectations among trainees and colleagues. The absence of representative cases is driven by professional prestige, competitive pressures, and fear of criticism. These forces encourage the showcasing of idealized performance, with ethical implications for informed consent, trainee preparedness, and the reliability of evidence used in systematic reviews. Through systematic review of video submission guidelines from 16 major surgical organizations, we demonstrate that while 68.75% now offer dedicated complication video categories, zero organizations require mandatory disclosure of complication rates, case volumes, or comparative operative times for standard video submissions. To improve the integrity of surgical communication, we propose adopting mandatory guidelines for video submission and presentation. These should require disclosure of essential contextual information, including the surgeon’s complication rate, the total number of procedures from which the case was selected, and how the operative time compares with typical practice. Promoting transparency and recognizing the educational value of managing complications are crucial steps toward aligning surgical education with real-world clinical reality.
