“Maximum precision using minimally invasive techniques.”Guiding principle of surgical practice
His surgical training is further strengthened by a Fellowship in Minimal Access Surgery, certification in robotic surgery and clinical- research training through Harvard Medical School's Global Clinical Scholars Research Training programme.
Dr Siddharthan Rajagopal has participated in more than 3,000 minimally invasive procedures across hepatopancreatobiliary, hernia and colorectal surgery. He also had the distinctive opportunity to closely observe the Da Vinci 5 during its pilot phase in the United States. His clinical aim is to reduce postoperative recovery time while maximising the effectiveness of every appropriately selected surgical intervention.
He is an Associate Fellow of the American College of Surgeons, a member of the Harvard Alumni Club, and a member of both the American Society of Colon and Rectal Surgeons and the Society of American Gastrointestinal and Endoscopic Surgeons. At SAGES 2023 in Montreal, Canada, he presented an abstract in the Emerging Technologies session, focused on opportunities for funding and collaboration around artificial intelligence, laparoscopy and robotics.
He is also the founder of SurgeOmniQ-X, an early-stage venture exploring artificial intelligence and advanced optical imaging to help surgical robots achieve superior outcomes. He advocates the ethical and safe use of artificial intelligence to advance surgery and foster disruptive, clinically meaningful innovation.

Does Dr Siddharthan Rajagopal perform laparoscopic and robotic surgery?+
Yes. Laparoscopic, robotic and open approaches are considered according to the diagnosis, evidence, patient needs and clinical suitability.
What should I bring to my first appointment?+
Bring recent reports and scans, a list of medicines, details of previous operations and a short timeline of your symptoms.
Will I always be advised minimally invasive surgery?+
No. Laparoscopic or robotic surgery is recommended only when it is clinically suitable and offers a meaningful advantage for your condition.
Does seeking a surgical opinion mean I need surgery?+
No. A surgical consultation clarifies the diagnosis and all available options. The right recommendation may be observation, medical treatment, a procedure, surgery or referral.
