Summary
This study developed a 3D simulation model for laparoscopic inguinal hernioplasty transabdominal preperitoneal (TAPP) repair. The model effectively enhanced surgical skills in trainees, demonstrating significant learning curves across multiple stages.
Area of Science:
- Surgical Simulation
- Medical Education Technology
- Laparoscopic Surgery
Background:
- Laparoscopic inguinal hernioplasty, specifically the transabdominal preperitoneal (TAPP) approach, requires specialized training.
- Traditional training methods may not fully replicate the complexities of laparoscopic procedures.
- Objective assessment of surgical skill acquisition is crucial for effective training.
Purpose of the Study:
- To develop and evaluate a novel 3D simulation model for transabdominal preperitoneal (TAPP) laparoscopic inguinal hernioplasty.
- To assess the learning curve and skill acquisition of surgeons using the 3D simulation model.
- To provide a standardized training tool for laparoscopic TAPP procedures.
Main Methods:
- An experimental study involving 18 participants divided into three groups: trainee surgeons (GE), experienced surgeons (GC), and non-experienced surgeons (GS).
- Participants underwent 6 simulation sessions focusing on 5 key stages of TAPP: peritoneal opening, preperitoneal space creation, structure identification, mesh placement, and peritoneal closure.
- Performance was evaluated across sessions to track skill development and learning curves.
Main Results:
- Trainee surgeons (GE) showed significant improvement from the 1st to 6th session in the 1st stage (p=0.05) and 5th stage (p=0.001).
- The non-experienced surgeons (SG) demonstrated a significant learning curve, with performance improving from the 1st to 6th session (p=0.001).
- No significant differences in skill acquisition were noted between the experienced and trainee groups by the end of the study period.
Conclusions:
- A systematized training approach using the 3D simulation model significantly enhances laparoscopic surgical skills.
- The 3D model provides a validated platform for both theoretical and practical training in TAPP procedures.
- Simulation-based training is effective in improving surgical proficiency and confidence in laparoscopic inguinal hernioplasty.
