About
Hung Leng Kaan is a pioneering researcher at the intersection of robotic surgery, flexible endoscopy, and minimally invasive gastrointestinal intervention. His work addresses some of the most pressing technical challenges in therapeutic endoscopy, from improving tissue resection techniques to developing robotic systems capable of performing complex surgical tasks through natural body orifices. Kaan's most influential contribution, "Sewing up the Wounds: A Robotic Suturing System for Flexible Endoscopy" (2020, 52 citations), demonstrates his drive to solve life-threatening clinical problems — specifically, enabling reliable perforation repair during endoscopic procedures without resorting to open surgery. Complementing this, his work on robot-assisted endoscopic resection and endoscopic full thickness resection has helped define best practices and future pathways for achieving superior oncological outcomes in gastrointestinal tumor removal. Beyond technical development, Kaan has thoughtfully examined the barriers to real-world clinical adoption of robotic endoscopy, and he has been forward-thinking in exploring how artificial intelligence, 3D imaging, and NOTES could reshape the field. His innovative work on deployable colon support structures further reflects his systems-level approach to endoluminal surgery. With over 130 cumulative citations, Kaan is an emerging authority shaping the next generation of intelligent, minimally invasive surgical robotics.
