Dwarika Hospital — Gastro, Bariatric & Laparoscopic Surgery Center
A surgeon who tells you the truth — even when it means not operating
Dr. Avinash Tank is a super-specialist bariatric, gastro & laparoscopic surgeon practising at Dwarika Hospital — Gastro, Bariatric & Laparoscopic Surgery Center in Ahmedabad, with 25+ years of surgical experience and 15+ years as a super-specialist. He holds an MCh in Surgical Gastroenterology from SGPGIMS, Lucknow — one of India's premier GI institutes — built on an MBBS and MS (General Surgery) foundation, with fellowships in liver, pancreas and bariatric surgery and advanced training in Japan & South Korea.
His practice spans four connected disciplines: surgical gastroenterology (the diagnosis and surgical treatment of stomach, liver, pancreas and bowel disease), bariatric & metabolic surgery for obesity and type 2 diabetes, GI cancer surgery, and advanced laparoscopic & endoscopic technique — chosen deliberately because a patient's gallbladder, hernia or cancer question rarely respects a single specialty's boundary.
Every patient is given an accurate diagnosis, an honest opinion on whether surgery is truly needed, and — where it is — the least-invasive effective option available. That philosophy is why 98% of patients recommend Dr. Tank, and why patients travel to him from across India and abroad for a second opinion.
Education, training & professional journey
Years are shown only where the underlying record confirms them — a gap below is a gap in the public record, not an omission.
Foundational medical degree and full clinical training.
Full general-surgery residency and registration ahead of super-specialisation.
Super-specialist training in GI, hepatobiliary, pancreatic & colorectal surgery at India's premier GI institute.
Focused, post-MCh fellowship training in each of these three areas.
Advanced hands-on exposure to techniques from two of the world's leading centres for minimally invasive GI surgery.
Prior hospital affiliations, ahead of his current practice at Dwarika Hospital — Gastro, Bariatric & Laparoscopic Surgery Center.
Specialist surgical care, all under one roof
Bariatric & metabolic surgery
Weight-loss & diabetes-reversal surgery for lasting metabolic health.
GI cancer surgery
Stomach, colon, liver, pancreas & oesophageal cancer surgery.
Gallbladder & hernia
Laparoscopic gallbladder removal and all types of hernia repair.
Liver & pancreas surgery
Advanced surgery for complex liver and pancreatic conditions.
Diagnostic & therapeutic endoscopy
ERCP, gastroscopy & colonoscopy for precise diagnosis and treatment.
Robotic surgery
Robotic-assisted precision for bariatric, hernia & GI cancer surgery.
Technique chosen for the patient, not the other way round
Dr. Tank's default is a laparoscopic-first approach — smaller incisions, less pain and a faster return home — stepping up to robotic-assisted surgery where its added precision genuinely changes the outcome, and using diagnostic & therapeutic endoscopy (gastroscopy, colonoscopy, ERCP) to reach an accurate diagnosis before any surgical decision is made at all.
