On December 28, the first operation in the country using the latest version of the robotic surgical system Revo-i was performed at the National Oncology Center located in the Bayanzurkh district of Ulaanbaatar. The liver transplant procedure was completed successfully.

The Revo-i system provides 3D visualization without the need for special glasses. The surgeon-controlled system of controllers allows the instruments to move with high precision, significantly enhancing the safety of the operations performed for patients. This is the latest advancement in the field of surgical robotics.

Of particular interest is the tactile sensation function that the robot possesses. This means that thanks to integrated electronic systems and artificial intelligence, the surgeon, while at the console, can "feel" the tissues that the robot is addressing, as well as receive alerts about complex areas.

The Revo-i robot has four manipulators that operate through small incisions. Three manipulators hold surgical instruments, while one holds a camera that provides a three-dimensional image of the surgical field on the display. The surgeon can control the movements of these "arms," making incisions, cutting tissues, and suturing.

Revo-i is the second surgical robotic system in the world to receive approval for real endoscopic operations. Previously, the only similar equipment in this category permitted for use was the Da Vinci robot from the American company Intuitive Surgical, local authorities reported.


The National Oncology Center of Mongolia (NOCM) performed its first robotic surgery on December 28, 2025, marking a significant event in its history. According to the Ministry of Health, Mongolia now ranks 70th in the world for the implementation and adaptation of robotic surgery.

In the past three years, Mongolia has been actively preparing for the implementation of robotic surgery. This advanced technology is already in use in 69 countries.

Since 2021, a project titled "Establishing a National Network for Cancer Prevention and Early Diagnosis" has been implemented, funded with 10 million euros under an agreement between the governments of Mongolia and Austria.


As part of this initiative, the National Center for Oncology Medicine (NCOM) acquired modern diagnostic and treatment equipment, including MRI, CT, an angiographic room, and a digital mammography system based on artificial intelligence. These innovations aim to meet international standards and improve early detection and treatment capabilities for cancer.

In 2022, NCOM also implemented new radiation therapy technologies based on linear accelerators, which is estimated to have increased cancer treatment capabilities by 20 years and improved access to medical services by 25%. Since last year, the center has begun performing surgeries to remove inoperable brain tumors and has independently conducted liver transplants following a successful first operation with a living donor in 2018 in collaboration with Korean surgeons from Samsung Medical Center.
