About me

Dr Ana (Ignjatovic) Wilson manages all aspects of gastrointestinal disorders including inflammatory bowel disease and functional bowel disorders, including irritable bowel syndrome, food allergy/intolerance and works closely with dieticians and nutritional therapists to treat patients holistically. She sees patients presenting with varied symptoms, including abdominal pain, bloating, rectal bleeding and weight loss amongst others.

Dr Wilson is a luminal gastroenterologist and specialist gastrointestinal endoscopist. She is nationally accredited Bowel Cancer Screening colonoscopist. Her specialist interests include general gastroenterology and early diagnosis, prevention and treatment of pre-cancerous lesions and cancer, through colonoscopy, in patients with inflammatory bowel disease and those at increased risk of developing colorectal cancer. She also leads the service for managing patients with consequences of cancer treatment including radiation proctopathy and anterior resection syndrome.

Dr Wilson qualified from University of Oxford in 2002. She obtained Membership of the Royal College of Physicians in 2005 and trained in gastroenterology and general internal medicine in Oxford. She spent three years at the Wolfson Unit for Endoscopy, St Mark's Hospital undertaking research in the use of colonoscopy in diagnosis and treatment of pre-cancerous lesions under the supervision of Prof Brian Saunders that led to an MD thesis at the Imperial College, London, and has published widely on the subject. After completing her training, Dr Wilson specialised further in management of complex inflammatory bowel disease and endoscopy at University College Hospital, London. She was appointed as Consultant Gastroenterologist and Specialist Endoscopist at St Mark's Hospital in December 2012. There she developed a service managing patients who experience gastrointestinal complications of cancer treatment (particularly after treatment for prostate, colon and gynaecological cancer). Since 2017 she has worked at The Royal Marsden hospital, leading GIANT (Gastrointestinal and Nutrition Team).

She has been an invited speaker at numerous national and international meetings and has contributed to a number of guidelines. Dr Wilson has active research in two main areas - detection and management of pre-cancerous lesions in colitis and functional outcome and quality of life after cancer treatment. She is a Deputy Director of St Mark's Bowel Cancer Screening Programme and a Co-Chair of RMP Colorectal Pathway Group.
