Surgical innovation and advances in technology have resulted in major developments in minimal invasive surgery over the last two decades. The Division of Colorectal Surgery, Department of Surgery, The University of Hong Kong has been at the forefront of this field and is continuing to develop new and innovative procedures to improve patients' well-being.

Professor Law Wai-Lun, Chief of the Division of Colorectal Surgery, is recognised for his work in innovative and minimal invasive surgery and conducting robotic operations. These procedures can significantly improve the postoperative recovery of patients and reduce any incision-associated complications.

As part of his research in this field Professor Law is currently looking into natural orifice surgery that will minimise surgical access and will leave no scars. This type of procedure will also improve patients' quality of care and recovery time.  He has also been active in developing advanced laparoscopic techniques, transanal endoscopic surgery, and natural orifice transluminal endoscopic surgery.

Professor Law is also a key teaching surgeon and is passing on his knowledge to the next generation of surgeons. Using the latest state-of-the-art equipment, including robotics, in the Department's Surgical Skills Centre he is able to provide realistic and practical training in minimal invasive surgery methods and techniques.
