5G Remote Robotic Surgery for Hepatic Echinococcosis in High-Altitude Region

Hepatic echinococcosis (HE) is a serious endemic parasitic disease in high-altitude regions like Xizang. Radical hepatectomy is the primary curative treatment, but expert resources are often concentrated in large medical centers. This prospective, single-arm study aims to evaluate the feasibility and safety of performing remote robotic hepatectomy using the Chinese Toumai™ robotic system over a 5G network. Ten patients in West China Hospital Tibet Hospital, Sichuan University (Lhasa, 3650m altitude) will undergo surgery performed by expert surgeons at West China Hospital (Chengdu). The primary focus is the surgical success rate and perioperative safety.

This study aims to evaluate the feasibility and safety of performing radical hepatectomy for hepatic echinococcosis in a high-altitude region (Lhasa, Xizang, 3650m altitude) utilizing the domestic Toumai™ robotic surgical system via 5G network communication. Hepatic echinococcosis is a significant endemic parasitic disease in high-altitude areas. While radical resection remains the definitive treatment, a disparity in the distribution of expert surgical resources poses challenges to patient access. This prospective study investigates the following: Technical Feasibility: To validate whether the 5G network performance, specifically regarding latency and image resolution in a high-altitude and long-distance transmission environment, meets the clinical requirements for real-time robotic surgery. 1. Operational Safety: To assess the impact of tele-robotic control on the precision required for complex hepatic procedures, such as managing critical vascular structures and dissecting cystic walls. 2. Clinical Outcomes: To analyze the efficacy and non-inferiority of the tele-robotic approach compared to traditional surgical methods by evaluating perioperative technical metrics and postoperative recovery indices. By establishing a closed-loop surgical connection between the center (Chengdu) and the remote site (Lhasa), the team will monitor real-time tele-interaction stability. This study includes robust contingency protocols for network instability or mechanical failure to ensure patient safety, providing clinical evidence for the standardization of remote hepatobiliary surgery in underserved regions.
