  • Overview

  • Dr. Siddhartha Bhattacharya is a distinguished Gastrointestinal, Bariatric, and Advanced Laparoscopic Surgeon with extensive training and experience in complex surgical procedures. After completing his MS in General Surgery from IPGMER, Kolkata, he earned a DNB in the same field. He later pursued a Fellowship in Minimal Access Surgery (FNB) at the prestigious GEM Hospital & Research Centre in Coimbatore, where he was trained in advanced laparoscopic hernia, gastrointestinal, and bariatric surgeries. He subsequently served as a Senior Consultant at GEM Hospital, Chennai, and has performed thousands of laparoscopic hernia repairs and bariatric procedures, gaining national recognition for his expertise and patient-centric approach.

  • Currently serving as a Consultant in the Department of Advanced Laparoscopic GI and Bariatric Surgery, Dr. Bhattacharya is known for his proficiency in a wide range of surgeries, including laparoscopic sleeve gastrectomy, gastric bypass, duodenojejunal bypass, colorectal surgery, and hepatobiliary procedures. His skills extend to complex cases such as stomach cancer, pancreatic tumours, choledochal cysts, and splenic conditions. He also specialises in single-incision bariatric surgeries and modern hernia repair techniques like TEP, TAPP, e-TEP-RS, and TAR. His innovative approach and surgical precision have made him a sought-after name in minimal access and metabolic surgery. Dr. Siddhartha Bhattacharya is a very experienced bariatric surgeon having the experience of hundreds of bariatric procedures, including all types of laparoscopic procedures. The treatment he offers is tailored to each patient’s disease. He does not believe in the notion of “one surgery fits all”. He is one of the few surgeons in India who is an expert in performing single incision (SILS) bariatric surgery. SILS bariatric surgery is virtually scarless bariatric surgery as the whole procedure is performed laparoscopically through a single keyhole deep in the umbilicus. He is the best Laparoscopic Surgeon in Kolkata.

  • Dr. Bhattacharya has contributed extensively to medical literature, with over 20 publications in reputed international journals and co-authorship of the book Clinics in Bariatric & Metabolic Surgery. His academic achievements include multiple best paper awards at national conferences such as AMASICON and OSSICON. As a committed educator and faculty member, he has demonstrated live surgeries across India and internationally, including in China and Bangladesh. His dedication to advancing surgical techniques and improving patient outcomes places him among the leading figures in minimally invasive and bariatric surgery in India.
