About
Dr. Hajime Imai is a leading figure in interventional gastroenterology, with a focused expertise in biliary stent technology and endoscopic management of pancreaticobiliary disorders. His most impactful work centers on improving the safety and efficacy of biliary covered self-expandable metal stents (C-SEMSs), a critical tool for treating malignant biliary obstructions. Dr. Imai’s key contribution is the development of a novel, standardized phantom model to objectively evaluate stent anti-migration properties—a persistent clinical challenge. His 2016 study, which has garnered 37 citations, systematically assessed six different C-SEMS designs using a retraction robot, providing the first rigorous, comparative data on stent resistance to displacement. This work has directly informed clinical device selection and spurred further innovation in stent design to reduce migration rates. Beyond this, Dr. Imai’s research portfolio encompasses advanced endoscopic techniques, including endoscopic ultrasound-guided drainage and cholangioscopy, contributing to less invasive treatments for complex biliary diseases. His methodological approach, combining engineering principles with clinical need, marks him as a translational researcher whose work bridges bench-top testing to bedside practice, significantly impacting patient outcomes in therapeutic endoscopy.
