With evolution of laparoscopic surgery, gone are the long hospital stays, pain, prolonged discomfort etc. But further research and technical evolution we are in an era where the surgeries can be performed through one single hole in the navel hence by adding on to the advantages of laparoscopic surgery, there’s additional cosmetic benefit. The final result is one single scar hidden within the navel so that the patient has no idea that a surgery has actually been performed. But this requires more technical skills from the surgeon’s perspective to give a safe result. Dr. Praveen Raj is credited to be one among the few surgeons in the world to have Single Incision Laparoscopic Gastric bypass and has also performed the largest numbers of such surgeries in the country.


Dr. Praveen Raj and his team is credited with performing the largest numbers of Single Incision surgeries in the country, which includes all varieties of procedures including a laparoscopic cholecystectomy, obesity surgery to even complicated cancer surgeries like cancer rectum, colon etc. He has also performed the first single incision laparoscopic Roux en Y gastric bypass in the country with the credit of having the largest numbers in the country in this surgery.

When countries are facing the problems of lack of co-ordination between surgeons and physicians, his efforts have made him author the "Guidelines for Metabolic (Bariatric) surgery in India" in the Guidelines book meant for Physicians of India.
