Dr Chapman qualified in 1997 from UCL Medical School and completed specialist training in London. His practice includes general gastroenterology with a specialist interest in pancreatobiliary medicine and hepatology. Conditions of particular interest include primary sclerosing cholangitis, IgG4 related cholangitis and pancreatitis, gallstones, chronic pancreatitis, hereditary pancreatitis, duodenal polyps, pancreatic cancer and cholangiocarcinoma. He performs general and therapeutic endoscopy (including leading on the duodenal polyp service) and complex ERCP including pancreatic endotherapy and cholangioscopy.
