Assistance with Artis Zeego Robot Imaging System in ERCP for biliary calculi

Objective To explore the value of Artis zeego robot imaging system endoscopic retrograde cholangiopancreatography （ERCP） for biliary calculi. Methods ERCP was performed on 12 patients with biliary tract dilation, diagnosed by B ultrasonography. Artis zeego robot was used simultaneously to acquire 3D images and biliary system reconstruction. The diagnostic consistency was assessed based on endoscopy and surgery if necessary. Results 3D rotating acquisition and biliary reconstruction were performed in the 12 patients. All diagnosis coincided with those of surgery and ERCP findings, achieving a consistency rate of 100%. Patients with extrahepatic bile duct stones of uncertain number （n = 2）, with suspected biliary duct calculi （ n = 1 ） and with suspected intrahepatic bile duct stones （ n = 2） under ERCP were all diagnosed by the robot imaging system. Conclusion During ERCP, 3D rotating image acquisition and biliary reconstruction with Artis zeego robot is helpful for precise diagnosis of biliary tract stones.
