Task-specific bench model training versus basic laparoscopic skills training for laparoscopic radical prostatectomy:...

Area of Science:

• Urology
• Surgical Education
• Minimally Invasive Surgery

Background:

• Laparoscopic urethrovesical anastomosis (LUA) after radical prostatectomy is a challenging surgical step for novice laparoscopic surgeons.
• A low-fidelity urethrovesical model (UVM) was developed to facilitate practice of this critical surgical anastomosis.
• Comparing task-specific training on the UVM versus basic laparoscopic suturing is crucial for surgical skill development.

Purpose of the Study:

• To compare the effectiveness of task-specific bench model training (anastomotic suturing on the UVM) with basic laparoscopic suturing.
• To evaluate the impact of UVM training on intracorporeal urethrovesical anastomosis performance.

Main Methods:

• A prospective, single-blinded, randomized controlled study involving 28 senior surgical residents, fellows, or staff surgeons.
• Participants were randomized to either the intervention group (UVM training) or the control group (basic laparoscopic suturing on a foam pad).
• Performance was assessed via videotaped tasks, scored using a laparoscopic suturing checklist (CL) and global rating scale (GRS), and timed.

Main Results:

• The UVM training group demonstrated significantly higher CL scores on both foam pad suturing and LUA tasks compared to the control group.
• The UVM group also achieved significantly higher GRS scores and shorter completion times for the LUA task.
• These findings indicate superior skill acquisition and performance with task-specific UVM training.

Conclusions:

• Task-specific bench model training using the UVM is superior to basic laparoscopic suturing drills on a foam pad.
• The UVM is an effective tool for improving surgical proficiency in LUA.
• This training approach enhances surgeon performance in a critical step of laparoscopic radical prostatectomy.
