EndoCogniAgent: Closed-Loop Agentic Reasoning with Self-Consistency Validation for Endoscopic Diagnosis
EndoCogniAgent is a pioneering AI framework designed for endoscopic diagnosis, addressing critical limitations of current systems like hallucinated evidence and error accumulation. It introduces a closed-loop agentic reasoning process with self-consistency validation, ensuring reliability and accuracy in medical diagnosis. The system uses a Central Decision Unit and Perceptual Expert Toolset, validating observations against knowledge and temporal consistency before updating the diagnostic state. This approach significantly improves diagnostic reliability and reduces errors in multi-step reasoning, as demonstrated by the new EndoAgentBench benchmark.
Executive Impact: What This Means for Your Enterprise
The implementation of EndoCogniAgent in an enterprise setting promises to revolutionize diagnostic workflows. By automating the iterative acquisition and validation of visual evidence, it reduces diagnostic errors, improves consistency across different cases, and frees up clinical staff for more complex tasks. The self-correction mechanism minimizes risks associated with AI hallucinations, making it a reliable tool for high-stakes medical environments. This leads to faster, more accurate diagnoses, ultimately enhancing patient outcomes and operational efficiency in healthcare enterprises.

Problem Statement
Endoscopic diagnosis is iterative, requiring progressive evidence acquisition and verification. Current AI systems fall short due to weak coupling between fine-grained perception and multi-step reasoning, leading to hallucinated evidence and uncorrected error accumulation. EndoCogniAgent addresses these by integrating validation into every reasoning step.
Methodology
EndoCogniAgent formulates diagnosis as a controlled state update. It features a Central Decision Unit for planning, a Perceptual Expert Toolset for evidence extraction, and an Internal Self-Consistency Validation (ISCV) mechanism. ISCV checks knowledge and temporal consistency before updating an episodic memory, ensuring validated observations condition subsequent planning. This closed-loop approach mitigates errors effectively.
Key Findings
Experiments on the EndoAgentBench benchmark (6,132 QA pairs from 11 datasets) show EndoCogniAgent achieves 85.23% average accuracy on perception and 71.13% clinical acceptance rate on reasoning. Ablation studies confirm ISCV and episodic state maintenance are critical. The system demonstrates adaptive orchestration of tools and iterative error correction, significantly outperforming general-purpose MLLMs.
Future Implications
EndoCogniAgent's framework offers a robust blueprint for AI in complex diagnostic scenarios, paving the way for more reliable and accountable medical AI. Future work includes extending the framework to temporal video reasoning and validating its utility in real clinical workflows, moving beyond API-based LLMs to reduce latency for real-time deployment.

Iterative Error Correction in Action
A case demonstrated ISCV intercepting hallucination. Initially, a single-pass baseline missed a polyp, returning 'normal mucosa'. EndoCogniAgent detected the visual discrepancy due to a mucosal protrusion, triggering corrective feedback. Over three iterative rounds, the agent resolved uncertainty through cross-validation and spatial localization, boosting diagnostic confidence from 0.3 to 0.9. This confirms that validation-gated updates effectively intercept early errors before they propagate.
