Embrella-assisted colonoscopy (EAC) significantly boosts adenoma detection rate (ADR) and adenomas per colonoscopy (APC) compared to standard colonoscopy (SC). This novel device improves detection of smaller and non-pedunculated adenomas, enhancing colon cancer screening.
Area of Science:
- Gastroenterology
- Endoscopy
- Cancer Screening
Background:
- Standard colonoscopy has limitations in adenoma detection.
- Novel devices are being developed to improve colonoscopic examination effectiveness.
- The Embrella is a new distal attachment designed to enhance colonoscopy.
Purpose of the Study:
- To evaluate the impact of the Embrella device on adenoma detection rate (ADR).
- To assess the effect of Embrella on adenomas per colonoscopy (APC).
- To compare Embrella-assisted colonoscopy (EAC) with standard colonoscopy (SC) in routine practice.
Main Methods:
- A randomized controlled trial involving 1,179 participants across 3 endoscopy centers in China.
- Participants were assigned to either Embrella-assisted colonoscopy (EAC) or standard colonoscopy (SC) groups.
- Key metrics recorded included ADR, APC, inspection time, pain scores, and adverse events.
Main Results:
- EAC significantly increased overall ADR (34.2% vs 24.6%) and APC (0.64 vs 0.44) compared to SC.
- EAC demonstrated improved ADR for adenomas <10 mm, non-pedunculated adenomas, and those in the transverse and left colon.
- Inspection time was slightly shorter with EAC, with no significant increase in pain scores or adverse events.
Conclusions:
- Embrella-assisted colonoscopy (EAC) is effective in increasing ADR and APC.
- The device shows particular benefit in detecting smaller and non-pedunculated adenomas.
- EAC offers a promising advancement for improving colonoscopic surveillance and colorectal cancer prevention.
