## Overview
Lpixel Inc. announced that 'EIRL Surgery LC', an AI system supporting laparoscopic cholecystectomy developed in collaboration with Olympus Corporation, received medical device manufacturing and marketing approval from the Japanese Minister of Health, Labour and Welfare in February 2026.
## Background and Purpose
Bile duct injury is a severe complication in laparoscopic cholecystectomy, occurring in approximately 600 cases annually, primarily due to organ misidentification. By combining Lpixel’s image analysis AI technology with Olympus’s expertise in endoscopes, this system utilizes learned 'tacit knowledge' from expert surgeons to assist in landmark recognition, aiming to prevent bile duct injuries.
## Features and Performance
During laparoscopic cholecystectomy, the product segments and displays four key anatomical landmarks on the surgical monitor:
- Extrahepatic bile duct
- Cystic duct
- S4 inferior margin
- Rouviere’s sulcus
Clinical evaluation involving 44 surgical videos and 12 doctors demonstrated improved accuracy in landmark recognition compared to manual identification without AI support.
## Future Prospects
With the cooperation of Olympus Corporation, Lpixel will proceed with evaluating the product in domestic medical institutions and accelerate the implementation of medical AI into society.
