Professional statement

Professor Sanjay Purkayastha is a consultant general surgeon with a specialist interest in bariatric and upper GI (gastrointestinal) surgery.


He regularly performs laparoscopic (keyhole) procedures for a wide variety of conditions. Patients seeking a highly trained and skilled bariatric surgeon can benefit from his leading expertise in all procedures in surgical weight loss management, including gastric bands, sleeve gastrectomies, gastric bypasses. He also provides the surgical management of type 2 diabetes.


Aside from bariatric and metabolic surgery, he is also extensively trained and practiced in upper and lower GI surgery for benign disease, anti-reflux surgery and surgery for all varieties of hernia. Patients often seek his first-class surgical care for conditions such as diverticulitis, achalasia, bowel obstruction, pancreatitis and gallstones, among other conditions. What's more, he is a digital and robotic surgery entrepreneur: Mr Purkayastha was one of the first surgeons in the UK to carry out robotic bariatric surgery.


He trained at Saint Mary’s Hospital Medical School and the Imperial School of Medicine London where he completed his BSc in 1997, MBBS in 2000 and his MD in 2007. He obtained his MRCS in 2004 and FRCS in 2010 from The Royal College of Surgeons of England. Throughout his training, he was awarded numerous times for excellence in teaching and patient care. He has also spent time during his training in the US at renowned centres such as Cook Country Hospital, the Cleveland Clinic and the Mayo Clinic.


More recently, during the Covid-19 pandemic, Professor Purkayastha and a GP colleague teamed up with Hollywood actor Thandie Newton in a campaign to provide one million surgical masks to care homes free of charge. He also worked closely with fashion retailer Burberry to provide St Mary's Hospital with one tonne of surgical gowns to help with the shortfall of PPE protection during the peak of the coronavirus pandemic. During the current Covid-19 surge, Mr Purkayastha has collaborated with Mr John Vincent and LEON to provide more than 300 meals per day for the ICU staff at St Mary's Hospital.


Professor Purkayastha is an avid researcher and educator. He has published over 250 peer-reviewed papers and nearly 8000 citations.

  • Having my surgery ay the Lindo Wing performed by Professor Purkayastha was as positive an experience as it could be. Everything was explained beforehand and my questions answered in a way that was clear to me. Postoperatively it was exactly the same.Every time I saw Professor Purkayastha I felt how comprehensive his care was and that he looked beyond the surgery. I had complete confidence in his care and feel fortunate that he performed my operation.

  • An amazing experience from start to finish. I’ve never had much faith in surgery after a bad experience in my teens but the Professor was reassuring, went to great lengths to calm my concerns by answering a plethora of questions and then performed the procedure neatly and swiftly. I felt in very safe hands!

  • Prof Purkayastha and his team were incredible, I felt so safe and cared for every step of the way. All stages of my unexpected surgery and treatment were thoroughly explained to me and I could ask as many questions as I needed. My stay in hospital was comfortable, I recovered extremely quickly and feel better than I have done for a long time thanks to the aftercare I received from Prof Purkayastha.
