I am a consultant gastroenterologist at Spire Leeds Hospital. I graduated with honours from Leeds University in 1992 and completed my postgraduate training in York, Bradford and the majority of time in Leeds as a lecturer in gastroenterology. I completed a PhD on genetic aspects of inflammatory bowel disease as an MRC Research Fellow in the molecular medicine unit before completing my clinical training. I was subsequently appointed as a consultant gastroenterologist to Leeds Teaching Hospitals NHS trust in 2005.

I have extensive experience in general gastroenterology and have spent 14 years as the lead clinician for the inflammatory bowel disease service. I also have extensive experience in upper GI endoscopy (gastroscopy) and colonoscopy including as a nationally accredited colonoscopist In the NHS bowel cancer screening programme. I have performed in excess of 6,000 endoscopic procedures.

I see patients with all aspects of gastroenterological symptoms such as dyspepsia (indigestion), dysphagia (difficulty swallowing), gastro-oesophageal reflux (GORD), Barrett’s oesophagus, peptic ulcer disease, coeliac disease, anaemia, irritable bowel syndrome, inflammatory bowel diseases (Crohn’s disease, ulcerative colitis and microscopic colitis) and investigation of suspected gastric or colon cancer.

I perform all modalities of therapeutic endoscopy including polypectomy, endoscopic mucosal resection, dilatation of strictures (eg in Crohn's disease) and colonic stent placement in obstructing cancers. Endoscopic mucosal resection (EMR) is a technique to remove large or small flat polyps that may otherwise require surgical resection. My upper GI endoscopy (gastroscopy) skills include all aspects of diagnostic and therapeutic procedures including oesophageal dilatations of strictures, endoscopic nasojejunal tube placement and Percutaneous Endoscopic Gastrostomy insertions. I also have wide experience in endoscopic treatment of upper GI bleeding including the modalities of oesophageal variceal injection and banding, gastric variceal histoacryl glue injections, argon beam coagulation, adrenaline injections and haemostatic clipping of bleeding lesions.

As the lead clinician for the inflammatory bowel disease service I developed the unit in Leeds to go from no to 6 IBD specialist nurses over the last 14 years and set up the biological drug infusion service, telephone clinics, combined clinics, a patient panel and a multidisciplinary team meeting. We have also established a program of national and local clinical trials. I was the Leeds and district Crohn’s and colitis UK (CCUK) medical advisor and had a national role on the research committee and British Society of Gastroenterology (BSG) IBD sub-committee. I recently stepped down from the lead clinician role but maintain a significant interest in IBD.

My interests outside medicine revolve around family, friends and sport. Having hung up my cricket and football boots some time ago, I am working hard at improving my golf whenever I’m not watching our two children play their sport.
