He served as Clinical lead of the Hepatopancreatobiliary Division and pioneered the use of Minimally invasive laparoscopic surgery for complex pancreatic and liver surgery in NTFGH. Under his leadership, Dr Thng and his team were able to perform minimally invasive surgery in complex hepatopancreatobiliary cases.

Dr Thng received his Bachelor of Medicine and Surgery form The National University of Singapore Yong Loo Lin School of Medicine. Subsequently, he completed his basic and advanced surgical training at the National University hospital and was admitted to the Specialist Accreditation Board Singapore as a Specialist surgeon.

He was also the Clinical lead for the Laparoscopic cholecystectomy Value-driven Outcome (VDO) programme at NTFGH where he was responsible for ensuring quality care for patients requiring a cholecystectomy. He also led the Diagnosis-related workgroup helping to increase hospital subventions in order to decrease cost to patients while providing quality healthcare.

On the research front, Dr Thng was recognised for his surgical technique and has been invited to present his surgical videos at numerous Best Video sessions during international surgical conferences. He also received the A-STAR-Medtech innovation grant ($500k) in 2017 to develop a novel wearable in-sole to monitor foot pressures.  He has also published in international peer-reviewed journals on resection of complex liver malignancies. As a Senior Clinical lecturer of NUS School of Medicine, he has been an examiner at both undergraduate and postgraduate level and has helped developed and trained the next generation of surgeons.
