Summary
The SPIDER surgical system is more challenging than conventional laparoscopy for surgeons of all experience levels. Tailored simulation training may improve proficiency with this innovative device.
Area of Science:
- Minimally Invasive Surgery
- Surgical Simulation
- Laparoscopic Techniques
Background:
- Laparo-endoscopic single-site (LESS) surgery evolved from conventional laparoscopy.
- The SPIDER surgical system aims to address LESS technical challenges.
- This study evaluates the SPIDER system's performance against standard laparoscopy.
Purpose of the Study:
- Compare the technical performance of the SPIDER surgical system and conventional laparoscopy.
- Assess performance using standardized tasks from the Fundamentals of Laparoscopic Surgery (FLS).
- Evaluate the impact of surgical experience on performance with both systems.
Main Methods:
- Twenty surgeons (10 residents, 10 experienced laparoscopists) participated.
- Participants performed FLS pegboard transfers and pattern cutting tasks on a simulator.
- Objective scores and subjective ratings compared conventional laparoscopy and the SPIDER system.
Main Results:
- Both inexperienced and experienced surgeons performed significantly better with standard laparoscopy than the SPIDER system.
- Statistical significance (p < 0.05) was observed for both tasks in both groups.
- Inexperienced surgeons found the SPIDER system equivalent to conventional laparoscopy only for the peg transfer task's ease of use.
Conclusions:
- The SPIDER surgical system presents greater challenges compared to conventional laparoscopy.
- Surgical experience did not negate the increased difficulty associated with the SPIDER system.
- Developing tailored simulation-based training programs is recommended to enhance surgeon proficiency with the SPIDER system.
