Methods: The clinical data of 55 patients with biliary stenosis who received EyeMax biliary and pancreatic imaging system with direct transoral choledochoscope in Yuhuangding Hospital, Yantai from December 2021 to December 2023 were retrospectively analyzed to observe the imaging characteristics and types of biliary stenosis, with pathological and long-term follow-up results as the gold standard. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of EyeMax visual impression and endoscopic pathology were evaluated, and the above five aspects were compared with magnetic resonance cholangiopancreatography (MRCP), and the success rate and safety of bile duct stenting under EyeMax microscope were evaluated. Results: According to the comprehensive judgment of imaging examination, laboratory examination, pathological diagnosis and follow-up, 34 of the 55 patients were finally diagnosed with benign bile duct stenosis, and 21 patients were finally diagnosed with malignant bile duct stenosis. The diagnostic sensitivity of EyeMax visual impression was 100% (21/21), the specificity was 94.1% (32/34), the positive predictive value was 91.3% (21/23), the negative predictive value was 100% (32/32), and the accuracy was 96.4% (53/55). The sensitivity of EyeMax pathological biopsy for the diagnosis of benign and malignant biliary stenosis was 13/14 (92.9%), the specificity was 100% (7/7), the positive predictive value was 100% (13/13), the negative predictive value was 7/8 (87.5%) and the accuracy was 95.2% (20/21). A total of 33 patients with bile duct stenosis underwent EyeMax endoscopic cholangiopancreatinal stent implantation, and the operation success rate was 100% (33/33). Postoperative complications occurred in a total of 4 patients, with a complication rate of 12.1% (4/33). Among the 4 patients, 3 patients had hyperamylasemia and 1 patient had mild pancreatitis. After conservative treatment such as acid inhibition, enzyme inhibition and anti-infection, they all recovered to normal within 3 days, and there were no serious complications such as gastrointestinal bleeding and perforation. Conclusion: EyeMax biliary and pancreatic imaging system can distinguish benign and malignant of most bile duct stricture with relatively high accuracy, and can complete bile duct stenting relatively safely and efficiently to relieve or partially relieve bile duct stricture.展开更多
