Experienced surgeons demonstrate improved pancreatoduodenectomy outcomes, but little is known about what distinguishes their practice. Furthermore, the concept of experience has been variably interpreted in the surgical literature. We investigated how 4 interpretations of experience influence pancreatoduodenectomy management decisions.
A survey assessing pancreatoduodenectomy practice patterns was distributed by 6 surgical societies. Regression analysis identified behaviors associated with 4 forms of experience: years in practice, surpassing the learning curve (≥50 pancreatoduodenectomies), high annual volume (≥25 pancreatoduodenectomy/year), and high career volume (>200 pancreatoduodenectomy).
In the study, 861 surgeons responded, representing 6 continents. Senior surgeons were more likely to use pancreatogastrostomy, dunking/invagination, and external stents (all P < .05). Sixty-five percent of respondents surpassed the learning curve, and these surgeons were more likely to use a 2-layer pancreatic enteric anastomosis, stents, and the Fistula Risk Score (all P < .05). High annual volume surgeons were more likely to use the same reconstruction on every case and autologous tissue patches but less likely to use the Roux limb technique and multiple drains (all P < .05). High career volume surgeons mirrored the behaviors of those surpassing the learning curve except for using the Fistula Risk Score.
Experience encompasses several components, each of which seems to influence decision making in different ways.
经验丰富的外科医生实施胰十二指肠切除术的效果更佳,但对于他们的手术操作特点却知之甚少。此外,外科文献中对经验的概念解读各异。我们研究了经验的四种解读方式如何影响胰十二指肠切除术的管理决策。
6个外科学会开展了一项评估胰十二指肠切除术实践模式的调查。回归分析确定了与四种经验形式相关的行为:执业年限、越过学习曲线(≥50例胰十二指肠切除术)、高年手术量(≥25例胰十二指肠切除术/年)和高职业生涯手术量(>200例胰十二指肠切除术)。
在该研究中,861名外科医生做出回应,代表六大洲。资深外科医生更有可能采用胰胃吻合术、套入/内翻术和外置支架(均P <.05)。65%的受访者越过了学习曲线,这些外科医生更有可能采用两层胰肠吻合术、支架和瘘管风险评分(均P <.05)。高年手术量的外科医生更有可能对每个病例采用相同的重建方式和自体组织补片,但采用Roux袢技术和多个引流管的可能性较小(均P <.05)。高职业生涯手术量的外科医生除了使用瘘管风险评分外,其行为与越过学习曲线的医生相似。
经验包含多个要素,每个要素似乎都以不同方式影响决策。
