Robot-assisted endoscopic submucosal dissection (RA-ESD) shows improved efficiency and reduced difficulty compared to conventional ESD (C-ESD). Further clinical studies are needed to confirm these preliminary findings in real-world settings.
Area of Science:
- Gastroenterology
- Minimally Invasive Surgery
- Robotics in Medicine
Background:
- Robot-assisted endoscopic submucosal dissection (RA-ESD) aims to overcome limitations of conventional ESD (C-ESD).
- Current evidence for RA-ESD is limited, primarily from preclinical studies.
Purpose of the Study:
- To systematically evaluate and compare the efficacy and safety of RA-ESD versus C-ESD.
- To synthesize existing evidence through a meta-analysis.
Main Methods:
- Systematic review and meta-analysis of comparative studies.
- Literature search conducted in major electronic databases adhering to PRISMA 2020 guidelines.
- Pooled continuous outcomes using mean differences and dichotomous outcomes using odds ratios with random-effects models.
Main Results:
- RA-ESD was associated with significantly shorter dissection and overall procedure times.
- Higher dissection speed and en bloc resection rates were observed with RA-ESD.
- RA-ESD demonstrated a lower rate of blind dissection and reduced risk of muscular injury, with no significant difference in perforation rates.
Conclusions:
- RA-ESD presents promising technical advantages over C-ESD, including enhanced efficiency and reduced difficulty.
- Preliminary findings suggest RA-ESD may improve procedural outcomes without increasing major adverse events.
- Further high-quality clinical studies are essential to validate the real-world effectiveness and safety of RA-ESD.
