Summary
A new robotic system, EndoFaster, provides real-time traction assistance for Endoscopic Submucosal Dissection (ESD). This technology enhances visualization and efficiency, proving non-inferior to conventional methods while reducing procedure time and complications.
Area of Science:
- Gastroenterology
- Medical Robotics
- Surgical Technology
Background:
- Endoscopic Submucosal Dissection (ESD) is crucial for early GI tumor resection but faces technical challenges.
- Limitations in visualization, traction, and instrument control hinder ESD procedures.
Purpose of the Study:
- To evaluate the efficacy and safety of the flexible auxiliary single-arm transluminal endoscopic robot (FASTER, EndoFaster) for ESD.
- To assess EndoFaster's impact on en bloc resection rates, dissection time, visualization, complications, and operator workload.
Main Methods:
- Two-stage validation: technical assessment of real-time control and a prospective, randomized multicenter trial (192 patients).
- Patients were randomized 1:1 to robotic-assisted ESD (EndoFaster) or conventional ESD.
- Primary endpoint: en bloc (R0) resection rate; secondary endpoints: dissection time, visualization, complications, workload.
Main Results:
- EndoFaster demonstrated stable, accurate motion performance.
- En bloc resection rates were comparable: 98.84% (EndoFaster) vs. 98.13% (conventional ESD), confirming non-inferiority.
- Significant reductions in dissection time (P=.00435), improved visualization, and decreased muscular injury and operator workload were observed.
Conclusions:
- The EndoFaster robotic system acts as a "third hand," enhancing submucosal visualization and traction control during ESD.
- Robotic assistance improves the safety and efficiency of ESD procedures without altering standard clinical workflows.
