Context and Challenge
Colorectal cancer (CRC) remains a significant global health concern, accounting for 1.92 million new cases and 9.3% of total cancer deaths worldwide in 2022. It is the third leading cause of cancer mortality. Most CRCs originate from neoplastic polyps, primarily adenomas and sessile serrated lesions (SSLs), following the "normal mucosa-adenoma-cancer" pathway.
Improving the screening and early detection of colorectal polyps is crucial. Colonoscopy is the gold standard, reducing CRC-related mortality by 67%. However, outcomes vary significantly due to endoscopist qualifications, leading to missed or misdiagnosed polyps (approximately 26% of adenomas and 27% of serrated lesions are overlooked). Current practices often involve unnecessary polyp removal for pathological evaluation, incurring costs and risks.
Advances in machine learning and deep learning have led to AI software like Computer-Aided Detection (CADe) and Computer-Aided Diagnosis (CADx). CADe has shown significant improvement in Adenoma Detection Rate (ADR), particularly for small polyps. CADx systems aim to enhance the accuracy of optical diagnoses, meeting target values set by ASGE and ACG.
Despite these advancements, the real-world clinical outcomes of these over 10 CADe and CADx devices available globally remain debated. This study aims to evaluate AI-assisted colonoscopy's benefits compared to standard and advanced imaging techniques through a network meta-analysis, compare various CADe devices, and assess CADx sensitivity/specificity for polyp detection and diagnosis, providing evidence-based guidance for therapeutic decisions.

Final Study Inclusion
The methodology involved a comprehensive search across PubMed, Web of Science, Embase, and Cochrane databases, adhering to PRISMA guidelines. The initial search yielded 14,672 articles, which were systematically narrowed down to 64 studies (52 RCTs and 12 clinical studies) involving 50,834 patients.
Top CADe Models for Adenoma Detection Rate (ADR)
This comparison highlights the leading AI-assisted detection models and their reported efficacy in improving the Adenoma Detection Rate (ADR) during colonoscopy, based on network meta-analysis.
| CADe Model | Relative Risk (RR) to Conventional Colonoscopy | Key Advantage / Mechanism |
|---|---|---|
| ENDOANGEL | 2.11 (1.37-3.25) |
|
| AQCS | 1.75 (1.29-2.37) |
|
| AI (General) | 1.70 (1.40-2.05) |

Highest Efficacy for Adenoma and Polyp Detection
ENDOANGEL model-assisted colonoscopy is the most effective method for detecting colorectal adenomas and polyps (97.8%). This system monitors withdrawal speed, alerts for blind spots, and improves detection of small adenomas, reducing human error.
Top CADe Models for Sessile Serrated Lesion (SSL) Detection
This comparison highlights the leading AI-assisted detection models and their reported efficacy in improving the Sessile Serrated Lesion (SSL) Detection Rate during colonoscopy, based on network meta-analysis.
| CADe Model | SUCRA Ranking Probability (%) | Key Advantage / Mechanism |
|---|---|---|
| Endocuff-AI | 94.4% |
|
| AI (General) | 86.4% |
|
| GI Genius | 84.2% |
|
| CAD EYE (Fujifilm) | 77.9% |

Highest Efficacy for Sessile Serrated Lesion Detection
The Endocuff-AI model showed the highest detection rate for SSLs at 94.4%. Its flexible wings flatten colonic folds, prevent slippage, and aid in detecting hard-to-find lesions.
Diagnostic Performance: CADx-Assisted vs. Physician Optical Assessment
This table compares the diagnostic performance of CADx-assisted colonoscopy with physician-alone optical assessment for colorectal adenomas, highlighting key metrics.

| Conclusion |

While CADx showed a modest, statistically significant increase in diagnostic sensitivity and specificity, the clinical relevance remains limited. Real-time polyp assessment using CADx did not significantly increase diagnostic sensitivity of neoplastic polyps during colonoscopy compared to optical assessment without CADx.
Case Study: ENDOANGEL System for Enhanced Colonoscopy
ENDOANGEL: A Real-Time Quality Improvement AI
The ENDOANGEL system exemplifies an advanced AI solution designed to revolutionize colonoscopy. It acts as a real-time quality improvement tool, addressing critical challenges in lesion detection and procedural standardization.
Key impacts and capabilities include:
- Real-time quality monitoring: Monitors withdrawal speed and duration, crucial for thorough examination.
- Blind spot alerts: Actively alerts endoscopists to potential missed areas due to scope slippage.
- Improved small adenoma detection: Significantly reduces human error in identifying subtle lesions.
- Standardization & consistency: Provides real-time feedback, standardizing inspection and reducing performance variability among endoscopists.
- Proven efficacy: Achieved 97.8% detection rate for colorectal adenomas and polyps, and 93.33% accuracy in assessing bowel preparation cleanliness.
This system's ability to provide objective, real-time feedback enhances procedural consistency and reduces endoscopist performance variability caused by subjective factors or external pressures, ultimately leading to improved patient outcomes.
