meerecompany (CEO Joon Koo Kim) announced on the 13th that Professor Gi Hong Choi of the Department of Surgery at Severance Hospital successfully performed a robotic left hemihepatectomy using the company’s surgical robot, Revo-i.

On April 30, Professor Choi of the Department of Surgery at Severance Hospital performed a robotic left hemihepatectomy using Revo-i on a patient with intrahepatic cholangiocarcinoma. The complex procedure involved not only resecting the left lobe of the liver but also dissecting lymph nodes around the hepatoduodenal ligament. Despite the difficulty, the surgery was successfully completed, and the patient is currently recovering stably without any risk of complications.

A left hemihepatectomy involves removing the diseased portion of the liver, including the left lobe. The complexity of the procedure varies depending on the size and location of the tumor. In recent years, minimally invasive approaches using laparoscopy and robotics have gained traction for their precision and advantages in patient recovery.

Notably, the procedure utilized an ultrasonic dissector capable of bloodless cutting, allowing for quicker and more precise tissue resection while minimizing bleeding. In this case, the Revo SONIC, an ultrasonic scalpel compatible with Revo-i, was used and proved effective in reducing intraoperative bleeding and tissue damage.

Professor Choi, a leading authority in robotic liver surgery in South Korea, previously achieved a national milestone by completing 100 robotic donor hepatectomies—the first in the country.

He stated, “Being able to perform such a complex hepatectomy using a domestically developed surgical robot is a significant advancement. We plan to further explore its use in donor hepatectomies. By continuing to build on these successful cases, we hope to showcase the full potential of Korean surgical robotics.”

Ho Kun Lee, Executive Vice President and Head of Surgical Robot Division at meerecompany, commented, “We are committed to reducing reliance on imported systems and expanding access to advanced surgical solutions through continued innovation in domestic medical technology.”

Revo-i has been steadily building its track record both in Korea and abroad, demonstrating clinical safety and performance. Following its first export to Paraguay, full-scale procedures are now underway in the region. Domestically, Revo-i is actively being used across multiple specialties at Severance Hospital, including hepatobiliary and pancreatic surgery, colorectal surgery, urology, and gastrointestinal surgery.
