Dr Yiannis Kallis  BA MA PhD MRCP

Summary

I am a Consultant Hepatologist and Gastroenterologist at the Royal London Hospital (Barts Health NHS Trust), and Honorary Consultant Transplant Hepatologist at the Royal Free London NHS Foundation Trust.

 

Training and experience

I studied medicine at Trinity College Cambridge. My basic and higher medical training in internal medicine and gastroenterology was undertaken across several London teaching hospitals, with subspecialty training in hepatology and pancreato-biliary medicine completed in the renowned centres at the Royal Free Hospital, Imperial College Healthcare and University College London Hospital. My research into liver fibrosis and regeneration, funded by a Medical Research Council Fellowship, led to the award of a PhD from Imperial College London. I have worked as an NHS consultant for five years.

 

Skills and expertise

I have expertise in the diagnosis and treatment of a full range of gastrointestinal and liver diseases with a particular focus on the management of liver test abnormalities, chronic diseases such as fatty liver, viral hepatitis, alcohol-related liver disorders, and on disorders of the pancreas, gallbladder and bile ducts. I have extensive experience in the management of complications of cirrhosis and liver transplantation, and offer non-invasive testing of liver scarring.

 

I am a highly skilled advanced endoscopist and provide a full range of diagnostic and therapeutic upper intestinal endoscopy and colonoscopy, with an emphasis on patient safety and comfort. I have particular expertise in therapeutic endoscopy of the bile duct and pancreas (ERCP) and am often referred complex cases.

 

Research

I remain active in clinical research and hold an Honorary Clinical Senior Lecturer position at Barts and the London School of Medicine and Dentistry. I am a principal investigator for multi-centre clinical trials on new treatments for liver disease and maintain a particular research interest in novel endoscopic therapies for pancreatic and bile duct malignancies.

 

Memberships and other roles

I am a member of the Royal College of Physicians, the British Society of Gastroenterology, and the British Association for the Study of the Liver.
