Minimally invasive gynecologic surgery subspecialists demonstrated superior skills in total laparoscopic hysterectomy and bilateral salpingo-oophorectomy (TLH-BSO) simulations. Residents, fellows, and general specialists showed comparable performance, with subspecialists completing the procedure fastest.
Area of Science:
- Minimally Invasive Gynecologic Surgery
- Surgical Simulation and Training
- Surgical Skill Assessment
Background:
- Evaluating surgical proficiency is crucial for patient safety and optimal outcomes in gynecologic procedures.
- Standardized simulation models offer a controlled environment to assess surgical skills across different training levels.
Purpose of the Study:
- To compare standardized scores and surgical confidence in total laparoscopic hysterectomy and bilateral salpingo-oophorectomy (TLH-BSO) among obstetrician-gynecologists (ob-gyns) with varying training.
- To validate a TLH-BSO simulation model for assessing surgical competency.
Main Methods:
- A prospective cohort study involved 68 ob-gyns across four training categories: residents, fellows, general specialists, and minimally invasive surgery subspecialists.
- Participants performed a standardized TLH-BSO simulation on a biological model, with pre- and post-simulation confidence assessments.
- Surgical performance was objectively scored by blinded experts using the Objective Structured Assessment of Technical Skills (OSATS).
Main Results:
- Minimally invasive gynecologic surgery subspecialists achieved the highest OSATS scores (91%) and were significantly faster in all procedural segments.
- Residents (56%), general specialists (63%), and fellows (64%) showed comparable overall performance, though fellows excelled in cuff closure and tissue extraction.
- Residents were the slowest performers across most surgical components.
Conclusions:
- Fellowship-trained minimally invasive gynecologic surgery subspecialists exhibit superior technical skills and efficiency in TLH-BSO simulations.
- The simulation model effectively differentiates skill levels, with residents, fellows, and general specialists demonstrating similar performance.
- Further research may explore targeted training interventions to enhance skills among less experienced groups.
