This study shows that surgeons improve significantly in middle pancreatectomy after 10-15 cases. Early stages had longer operation times and more blood loss, but later stages showed no significant differences in outcomes.

Area of Science:

  • Surgical Oncology
  • Gastroenterology
  • Medical Education

Background:

  • Middle pancreatectomy is a complex surgical procedure.
  • Understanding the learning curve is crucial for improving surgical outcomes and patient safety.

Purpose of the Study:

  • To evaluate the learning curve associated with middle pancreatectomy.
  • To compare surgical outcomes at different stages of experience for a single surgeon.

Main Methods:

  • Retrospective analysis of 48 middle pancreatectomy cases performed by a single surgeon.
  • Cases were divided into 10 stages (5 cases per stage).
  • Key outcomes analyzed include operation time, blood loss, complications, margin status, and hospital stay.

Main Results:

  • No significant differences were observed in surgical complications, negative margin rates, or postoperative hospital stay across the 10 stages.
  • Significant reductions in median operation time and blood loss were noted between the first two stages and later stages (P<0.01).
  • No significant differences in operation time or blood loss were found among stages 3 through 10.

Conclusions:

  • A surgeon can achieve proficiency in middle pancreatectomy after approximately 10-15 cases.
  • Early surgical experience is associated with longer operation times and greater blood loss, which diminishes with subsequent cases.
