Abstract Background Decision-making under uncertainty may be influenced by an individual’s personality. The primary aim was to explore associations between surgeon personality traits and colorectal anastomotic decision-making. Methods Colorectal surgeons worldwide participated in a two-part online survey. Part 1 evaluated surgeon characteristics using the Big Five Inventory to measure personality (five domains: agreeableness; conscientiousness; extraversion; emotional stability; openness) in response to scenarios presented in Part 2 involving anastomotic decisions (i.e. rejoining the bowel with/without temporary stomas, or permanent diversion with end colostomy). Anastomotic decisions were compared using repeated-measure ANOVA. Mean scores of traits domains were compared with normative data using two-tailed t tests. Results In total, 186 surgeons participated, with 127 surgeons completing both parts of the survey (68.3 per cent). One hundred and thirty-one surgeons were male (70.4 per cent) and 144 were based in Europe (77.4 per cent). Forty-one per cent (77 surgeons) had begun independent practice within the last 5 years. Surgeon personality differed from the general population, with statistically significantly higher levels of emotional stability (3.25 versus 2.97 respectively), lower levels of agreeableness (3.03 versus 3.74), extraversion (2.81 versus 3.38) and openness (3.19 versus 3.67), and similar levels of conscientiousness (3.42 versus 3.40 (all P <0.001)). Female surgeons had significantly lower levels of openness (P <0.001) than males (3.06 versus 3.25). Personality was associated with anastomotic decision-making in specific scenarios. Conclusion Colorectal surgeons have different personality traits from the general population. Certain traits seem to be associated with anastomotic decision-making but only in specific scenarios. Further exploration of the association of personality, risk-taking, and decision-making in surgery is necessary.

探索手术实践的变化：外科医生的性格会影响吻合决策吗？

摘要 背景不确定性下的决策可能会受到个人性格的影响。主要目的是探索外科医生性格特征与结直肠吻合决策之间的关联。 方法世界各地的结直肠外科医生参与了一项由两部分组成的在线调查。第 1 部分使用大五量表来评估外科医生的特征，以测量性格（五个领域：宜人性、尽责性、外向性、情绪稳定性、开放性），以响应第 2 部分中提出的涉及吻合决策的场景（即在有/没有临时造口的情况下重新连接肠道，或通过末端结肠造口术永久改道）。使用重复测量方差分析来比较吻合决策。使用双尾 t 检验将性状领域的平均得分与规范数据进行比较。 结果共有 186 名外科医生参与，其中 127 名外科医生完成了调查的两个部分（68.3%）。131 名外科医生为男性（70.4%），其中 144 名来自欧洲（77.4%）。百分之四十一（77 名外科医生）在过去 5 年内开始独立执业。外科医生的性格与一般人群不同，情绪稳定性水平显着较高（分别为 3.25 比 2.97），宜人性水平较低（3.03 比 3.74），外向性（2.81 比 3.38）和开放性（3.19 比 3.67），且水平相似责任心（3.42 与 3.40（所有 P <0.001））。女性外科医生的开放程度显着低于男性（P <0.001）（3.06 vs 3.25）。个性与特定情况下的吻合决策相关。 结论结直肠外科医生具有与普通人群不同的性格特征。某些特征似乎与吻合决策相关，但仅限于特定情况。有必要进一步探索性格、冒险精神和手术决策之间的关系。
