Dr Hamlin has extensive experience in colonoscopy and sigmoidoscopy including the therapeutic modalities of polypectomy, EMR, dilatation of strictures (eg in Crohns 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. 

Dr Hamlin's upper GI endoscopy skills include all aspects of diagnostic and therapeutic procedures including oesophageal (balloon and KAD) dilatations of strictures, endoscopic nasojejunal tube placement and Percutaneous Endoscopic Gastrostomy insertions. He also has a 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.

Dr Hamlin is a graduate of Leeds University where he spent five happy years as an undergraduate. As a result he has not strayed far from Yorkshire having completed his postgraduate training at York, Bradford and the majority of time in Leeds, both as the Lecturer in Medicine and Gastroenterology and as registrar to the liver unit at St Jamess hospital. He 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 as a registrar. and was subsequently appointed as a consultant at Leeds General Infirmary in January 2005 having spent a year in the locum post.
