He had previously worked as a surgical fellow for 2 years at the world-renowned Mayo Clinic Rochester performing numerous complex surgical procedures. He is well-recognized as an international thought leader due to his vast clinical experience and extensive research work in the field. Dr Goh has received several awards and has been an invited member to numerous international expert consensus panels. 

Presently, he is one of the most experienced surgeons in Southeast-Asia for laparoscopic HPB surgery. Since returning to Singapore in 2011, he has personally performed over 800 laparoscopic and robotic major HPB surgeries as the lead surgeon and mentored/proctored over a dozen subspecialty regional colleagues in many more such procedures. He is widely-recognized as an international expert in minimally-invasive HPB surgery. Regionally, Dr Goh is a pioneer in advanced laparoscopic HPB surgery and is frequently invited to lecture and proctor local/regional surgeons. He pioneered robotic HPB surgery in the region in 2013 and has personally performed over 150 robotic major HPB surgeries as the main console surgeon. He is the only local robotic HPB proctor and has tutored over a dozen subspecialty colleagues in the region in numerous robotic HPB procedures.

Dr Goh frequently uses transplant oncology techniques to perform complex multi-organ resections with major vascular reconstructions for borderline-resectable cancers which may be considered inoperable by other surgeons. He is also experienced in treating rare conditions such as choledochal cysts, gastrointestinal stromal tumours(GIST), neuroendocrine (carcinoid) tumours and pancreatic cystic tumours such as intraductal papillary mucinous neoplasms (IPMN).
