BACKGROUND: Robotic-assisted surgery has transformed the surgical management of complex oncologic diseases by enhancing precision, visualization, and surgeon ergonomics. However, access to expert robotic oncologic care remains geographically restricted. Telesurgery offers a potential solution to overcome this disparity, though concerns regarding latency, reliability, and oncologic safety have limited its widespread adoption.
OBJECTIVE: To evaluate the technical feasibility, safety, and perioperative outcomes of the first North-to-South India tele-robotic cancer surgeries performed using the SSI MANTRA robotic system over a dedicated fiber-optic network.
METHODS: Two patients, one with locally advanced lower oesophagus and gastro-oesophageal junction tumour, and one with locally advanced carcinoma low rectum underwent tele-robotic surgery in March 2025. The Master Surgeon Console was located in Gurugram (North India), while the patient-side robotic system was positioned in Bangalore (South India), separated by approximately 2,100 km. A secure, encrypted, dual-redundant fiber-optic network was established. Network performance parameters, intraoperative events, and perioperative outcomes were prospectively recorded and analyzed.
RESULTS: Both procedures were completed successfully without network interruption, robotic malfunction, or conversion. Total system latency ranged from 160-170 ms, bi-directional network latency from 35-40 ms, and packet loss remained below 0.1%. Operative time, blood loss, and postoperative recovery were comparable to conventional on-site robotic surgery. No major intraoperative or postoperative complications occurred.
CONCLUSION: This study demonstrates that North-to-South India tele-robotic oncologic surgery using the SSI MANTRA system is technically robust, clinically safe, and oncologically sound when supported by dedicated fiber-optic connectivity. This approach represents a scalable strategy to improve access to advanced cancer surgery across geographically diverse regions.
