Hansei (): The Surgeon's Quiet Reckoning.

This manuscript uses two personal surgical cases to explore hansei, the Japanese discipline of structured self-reflection, as a framework for technical and professional growth. The first case illustrates the limits of technical perfection and the inevitability of some complications. The second reveals the cost of acting on overcaution. Together, they trace the difficult boundary between error, prudence, and inherent surgical risk. The discussion contrasts hansei's explicit, disciplined acknowledgment of shortcomings with the Western tendency to obscure responsibility through passive language and fear of reputational harm. The manuscript argues that adopting hansei in surgical culture can transform regret into actionable improvement, enhance morbidity and mortality reviews, and strengthen training by normalizing open discussion of fallibility. Ultimately, hansei is presented not as self-punishment but as a technical and ethical tool to refine judgment, maintain integrity, and improve patient care.
