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 include working as a trauma surgeon in one on London’s busiest Major Trauma Centres at St. Mary’s Hospital, Paddington, London. Mr Purkayastha’s general surgery practice includes laparoscopic surgery for hernias of all kinds, gall bladder surgery and anti-reflux surgery (surgery for treatment of severe heartburn) as well as emergency surgery work outside trauma that includes management of conditions such as appendicitis, gallstones, pancreatitis, bowel obstruction, hernia emergencies and the management of many other conditions that present with abdominal pain. His NHS practice is at St. Mary’s Hospital, Praed Street, London

As a bariatric surgeon, he deals with weight loss management and surgery for obesity and associated diabetes and other conditions such as obstructive sleep apnoea, high blood pressure, high cholesterol, musculoskeletal pain, polycystic ovarian syndrome and obesity related infertility. He routinely carries out gastric bands, sleeve gastrectomies and gastric bypasses all laparoscopically (key hole surgery). He was also one of the first surgeons in the UK to carry out robotic Bariatric surgery. Mr Purkayastha also carries out revisional bariatric surgery. Mr. Purkayastha provides all his Bariatric surgery data to the NBSR (National Bariatric Surgery Registry) as he is a believer of transparency of results and outcome/volume based surgery ensuring the safest and best results for patients. Bariatric surgery not only helps patients with sustained weight loss but it has been shown to help many patients with newly diagnosed or even longstanding diabetes (type 2). Many patients with poor blood sugar control will get excellent results after this type of surgery with up to 80% getting remission of their diabetes within a year or two of the surgery. Many patients have a significant reduction in their diabetes medication needed after surgery and a large number even go on to need no tablets or even come off their insulin injections after bariatric surgery as their blood sugar becomes so well controlled. Since December 2014, NICE (National Institute for Care Excellence), has recommended bariatric surgery for patients with a BMI of 30 or over with type 2 diabetes this reflects the national results for treating diabetes with this sort of surgery.
