Summary

Achieving surgical competence in laparoscopic-assisted vaginal hysterectomy requires approximately 30 procedures per surgeon. This learning curve significantly reduces complication rates and improves patient outcomes in teaching hospitals.

Area of Science:

  • Minimally Invasive Surgery
  • Surgical Education
  • Gynecologic Surgery

Background:

  • Laparoscopic-assisted vaginal hysterectomy (LAVH) is a complex procedure requiring specialized skills.
  • Determining the learning curve and proficiency benchmarks is crucial for surgical training in teaching hospitals.

Purpose of the Study:

  • To evaluate factors influencing proficiency in LAVH.
  • To estimate the number of procedures needed to achieve surgical competence in LAVH.

Main Methods:

  • Analysis of 929 LAVH cases performed by 33 surgeons.
  • Evaluation of learning curve, surgical duration, hemoglobin change, conversion rates, and complications.
  • Comparison of surgeons' initial 30 cases (Group A) versus subsequent cases (Group B).

Main Results:

  • A learning experience of 30 LAVH cases was identified as a benchmark for proficiency.
  • Significant reductions observed in intraoperative complication rates (4.2% to 0.5%) and postoperative complications (12.9% to 7.0%) after 30 cases.
  • Decreased hemoglobin drop (-0.8 to -0.5 g/L) and shorter surgical duration were noted, though duration was not a reliable learning endpoint.

Conclusions:

  • Proficiency in LAVH requires approximately 30 procedures per surgeon to achieve low complication rates.
  • Surgical duration alone is insufficient to assess the learning effect in LAVH.
