Professional background

Dr. Haidry is a consultant gastroenterologist and interventional endoscopist at University College Hospital, London. He trained at St Mary's Hospital in London and completed his specialist gastroenterology training in North East London. He was then appointed to a two-year academic fellowship at UCL where he examined state of the art and innovative diagnostic and therapeutic endoscopic techniques for the diagnosis and treatment of early cancers arising in the gastrointestinal tract.

He was appointed as a consultant in 2011. He was until recently the director of endoscopy for the division of gastroenterology at University College Hospital and leads the upper GI interventional endoscopic unit. His main interests are therapeutic and innovative endoscopic procedures. In particular he has focused his interest in pre-malignant and malignant disorders of the upper gastrointestinal tract, with a particular interest in Barrett’s neoplasia, Squamous neoplasia, oesophageal cancer and metabolic and bariatric endoscopic procedures such as Duodenal mucosal resurfacing (DMR) and Endoscopic Sleeve Gastroplasty (ESG).

He has an academic position of associate professor at UCL where he supervises his team to generate research into the endoscopic techniques and procedures he carries out to improve and streamline the care we give to our patients. His research is focused on existing and novel endoscopic imaging technologies for detecting early cancers such as artificial intelligence. His other main research focus is minimally invasive techniques for treating cancers of the upper gastrointestinal tract and continues to lead and be involved actively on several national and international clinical trials in these fields.

Research interests

Upper gastrointestinal disorders including managing gastro-oesophageal reflux, diagnosis and treatment of Barrett’s oesophagus, irritable bowel syndrome, gastrointestinal cancers.

Diagnostic endoscopy and colonoscopy as well as therepeutic upper gastrointestinal endoscopy including endoscopic resection, radiofrquency abaltion, yag laser, endoscopic ultrasound, stenting and dilatation of strictures, peg placement for feeding.
