Dr Amitabha Das
Upper Gastrointestinal & Weight Loss Surgeon

Dr Amitabha Das

Dr Amitabha Das

Dr Amitabha Das is a highly experienced upper gastrointestinal and weight loss surgeon that has been performing complex laparoscopic (“keyhole”) surgery since 2007.

Dr Das routinely performs some of the most technically demanding gastrointestinal surgical cases an upper-GI surgeon will ever face in their career, such as major cancer resections of the stomach, liver and pancreas. He has deep foundational surgical skills developed performing these more technically demanding areas of laparoscopic surgery, which he applies to his bariatric surgical work, such as the gastric sleeve and the gastric bypass.

Dr Das holds both public and private hospital appointments and can cater to all patients. He performs routine surgery as some of South-West Sydney’s highest volume public hospitals.

Dr Das also teaches other surgeons advanced techniques in upper-GI surgery.
