Mr Sanjay Purkayastha is a consultant general surgeon with a specialist interest in bariatric and upper GI surgery. He is also a senior lecturer at Imperial College London. His research interests are varied and include surgical education especially digital mobile technologies, clinical research in bariatric and metabolic surgery, assessing the health of healthcare organisations, single port laparoscopic surgery and surgical evidence synthesis. He has a busy general surgery practice both for elective (planned) surgery and emergencies which includes working as a trauma surgeon in one of London’s busiest major trauma centres at St Mary’s Hospital.

Mr Purkayastha was one of the first surgeons in the UK to carry out robotic bariatric surgery. He is one of four surgeons at the Imperial Weight Centre, which is a Tier 3 and Tier 4 service for weight loss management and surgery for obesity. He routinely carries out gastric bands, sleeve gastrectomies and gastric bypasses, all via laparoscopic surgery (keyhole surgery).
