Dr Ng’s Expertise in Colorectal Cancer Surgery
Dr Ng has been recognised as a regional expert in minimal invasive colorectal cancer surgery. In addition to laparoscopic (keyhole) surgery, he is experienced in many specialised techniques including robotic surgery, transanal surgery and colon stenting.
He regularly receives invitations to present his experience and surgical technique at local and international surgical conferences. Colorectal Surgeon, Dr Ng is recognised for his surgical skill and is one of few surgeons who has performed live demonstration surgery on numerous occasions locally and internationally, sharing his technique with other surgeons.
He specialises in difficult surgery for rectal cancer where sphincter (anus) preservation is difficult. He has been able to perform anus preserving surgery successfully (with cancer clearance) in situations where other surgeons have found difficult due to his expertise and experience with specialised techniques like robotic surgery and transanal (total mesorectal excision) surgery.
While he was at Singapore General Hospital, he had the highest caseloads of robotic colorectal surgery and transanal surgery. These days, he is regularly sought as a trainer and teacher of advanced techniques to other surgeons.
For all colorectal cancer surgery he routinely performs extended lymph node dissection, a technique developed in Japan and Korea, which is seldom performed elsewhere in the world (including Singapore). With the Japanese/Korean technique he is able to safely remove nearly double the usual number of lymph nodes that are usually removed in the conventional technique. This technique although is more technically demanding and time consuming, potentially improves cancer clearance for patients with more advanced cases.
The vast majority (~90%) of his colorectal cancer work is performed minimally invasively (laparoscopic/keyhole, robotic, transanal), so as to reduce the wounds and hasten the postoperative recovery.
In advanced cases where the cancer has caused acute blockage of the intestines, Dr Ng performs colon stenting to relieve the obstruction before performing the cancer operation. Without colon stenting, these patients would conventionally have required a risky emergency open surgery and will often also need a stoma (bag) as part of the operation. Colon stenting will usually allow for minimal invasive (keyhole) cancer surgery without the need for stoma (bag) creation to be performed instead. Dr Ng is a pioneer in Singapore of this technique with a large case experience, and is frequently sought after to share and teach his technique.
