- Bariatric & GI surgeries in his career
His own career record, as published by his practice.
Dr. Avinash
Tank
DIRECTOR & CHIEF SURGICAL GASTROENTEROLOGIST
Trained at SGPGIMS — India's premier GI institute — with advanced fellowships in Japan and South Korea.
His practice is built around minimally invasive surgery for the digestive system — gallbladder and hernia work, complex liver and pancreatic resections, GI cancer surgery, and bariatric procedures for patients whose weight has stopped responding to everything else.
Patients are told what an operation can and cannot achieve before they consent to it. Where surgery is not the right answer, that is said plainly.
