Overview

This Centre of Excellence for Gastrointestinal Sciences brings Medical Gastroenterology, Surgical Gastroenterology, and Liver Transplantation together under one integrated program — a single destination for the diagnosis, treatment, and long-term management of every digestive and liver condition.

Rather than navigating between separate departments, patients are cared for by one coordinated team of medical gastroenterologists, GI and HPB surgeons, transplant specialists, hepatologists, dietitians, and critical care experts — working in tandem to deliver precise diagnosis, minimally invasive treatment wherever possible, and seamless continuity of care from the first consultation through recovery and follow-up.

Our endoscopy suite has been recognised as a Centre of Excellence in Endoscopy under the ENDOSAFE accreditation by the Consortium of Accredited Healthcare Organisations (CAHO), India — a benchmark for procedural safety, infection control, and quality in endoscopic care. We have also partnered with the Mount Sinai Health System, New York, to align our protocols for patient safety, quality assurance, and infection control with global best practices.
