Pancreaticoduodenectomy: minimizing the learning curve

Area of Science:

• Surgical Oncology
• Gastrointestinal Surgery
• Medical Education

Background:

• Pancreaticoduodenectomy (PD) outcomes are known to improve with increased surgeon experience.
• Assessing the learning curve for PD is crucial for optimizing patient care and surgical training.

Purpose of the Study:

• To analyze PD outcomes over time to identify improvements related to surgeon learning.
• To evaluate the impact of surgical experience on operative factors and patient outcomes.

Main Methods:

• Retrospective analysis of 124 consecutive PD cases performed by a single surgeon over 4 years (July 2011-June 2015).
• Examination of operative factors (operative time, blood loss) and 90-day outcomes (length of stay, morbidity, mortality, readmission).
• Analysis of trends in outcomes and negative margin rates over the study period.

Main Results:

• Median operative time significantly improved over the 4-year period.
• Negative margin rates for PD, particularly for pancreatic adenocarcinoma, significantly improved over time (91.1%).
• No significant changes were observed in median blood loss, length of stay, pancreatic fistula rate, overall morbidity, major morbidity, mortality, or readmission rates.

Conclusions:

• While operative time and margin rates improve with experience, the learning curve for PD may not significantly impact all patient outcomes.
• Appropriate surgical training, high-volume centers, mentorship, and multidisciplinary teams can mitigate the learning curve's effect on patient outcomes.
