Resident gynecologists and total hysterectomy

Area of Science:

• Surgical Education
• Gynecologic Surgery
• Resident Training

Background:

• Acquiring surgical proficiency requires adequate operative experience.
• Hysterectomy, a common gynecologic procedure, has distinct abdominal and vaginal approaches.
• Standardizing resident training for hysterectomy is crucial for patient safety and outcomes.

Purpose of the Study:

• To determine the number of abdominal total hysterectomy (ATH) and vaginal total hysterectomy (VTH) procedures necessary for obstetrics and gynecology residents to achieve surgical proficiency.
• To analyze the learning curve for ATH and VTH based on surgical time, blood loss, and tumor weight.

Main Methods:

• Retrospective analysis of resident surgical performance in ATH and VTH over a three-year residency.
• Assessment of technical skill improvement using surgical time, blood loss, and resected tumor weight.
• Comparison of resident performance metrics against attending surgeon benchmarks.

Main Results:

• For ATH, proficiency was indicated by reduced blood loss after 25-49 cases and shortened surgical time after 75+ cases.
• Early VTH residents (less than 15 cases) exhibited higher blood loss compared to staff surgeons.
• Significant differences in surgical time were observed between residents and staff for VTH across all resident experience levels.

Conclusions:

• Performing over 75 ATH procedures appears adequate for developing proficiency in abdominal total hysterectomy within a three-year residency.
• Current training recommendations for VTH are insufficient, as 25 procedures do not lead to proficiency.
• Additional training and experience in vaginal total hysterectomy are necessary for residents to achieve competency.
