Summary

SURGENT is a surgical multi-agent assistance system designed to overcome the limitations of web-based Large Language Models in complex surgical care. It integrates a Tree-of-Thought planner, multi-department collaboration agents, and retrieval-augmented reasoning, leveraging clinical guidelines and biomedical literature. A novel memory design in SURGENT manages both long-term patient histories and short-term working summaries, facilitating contextualized and consistent reasoning. Evaluated across five perioperative tasks—case analysis, surgical plan simulation, safety monitoring, complication risk assessment, and rehabilitation guidance—SURGENT demonstrated superior performance compared to baseline LLMs and existing medical multi-agent frameworks, providing recommendations better aligned with patient histories. Ablation studies identified DeepSeek as an effective locally deployable backbone model, enabling privacy-preserving deployment without relying on centralized services, positioning SURGENT as a practical and trustworthy advancement for surgical assistance.

Key takeaway

For AI Scientists and medical technology developers building surgical assistance systems, SURGENT demonstrates a robust architecture for enhancing clinical decision support. You should consider integrating multi-agent frameworks with specialized memory management and retrieval-augmented reasoning to overcome standard LLM limitations. Prioritize locally deployable models like DeepSeek to ensure patient data privacy and enable trustworthy, equitable, and secure deployments in healthcare settings.
