Training and experience

Dr Ana Wilson qualified in 2002, from the University of Oxford. Then in 2005, she achieved membership of the Royal College of Physicians and trained in both gastroenterology and general internal medicine in Oxford. Dr Wilson spent three years researching the use of colonoscopy in diagnosis and assessment of pre-cancerous polyps at the Wolfson Unit for Endoscopy, St Marks Hospital (MD Res, Imperial College 2011).

After finishing her training, in 2012 she was appointed as a Consultant Gastroenterologist and Specialist Endoscopist at St Mark’s Hospital. She has since contributed heavily to a number of international guidelines on the use of advanced imaging in lesion recognition including those in inflammatory bowel disease.

Dr Wilson also leads the service at St Mark’s Hospital for management of patients with gastrointestinal consequences of cancer treatment (eg. Low anterior resection syndrome, radiation proctopathy). As well as this, she is currently Senior Clinical Lecturer at Imperial College London.

Clinical Interests

Dr Ana Wilson is exceptionally experienced in treating patients with a wide range of conditions, including:

  • Colorectal polyps (Bowel Cancer Screening accredited colonoscopist)
  • Inflammatory bowel disease (Crohn’s and Ulcerative Colitis)
  • Functional disorders such as Irritable Bowel Syndrome
  • Food intolerances
  • Gastrointestinal consequences of cancer treatment following surgery and radiotherapy for colorectal cancer, gynaecological and prostate cancers

Dr Wilson's reputation in her ability to manage the consequences of cancer and its treatment is largely regarded as being world-class. For this reason, at St Marks Hospital, Harrow, she is responsible for caring for patients with digestive system problems following surgery, chemotherapy and radiotherapy.

Dr Ana Wilson is nationally accredited bowel cancer screening colonoscopist and specialises in advanced and therapeutic colonoscopy, and in difficult cases that could require general anaesthetic.  

Research interests

Dr Wilson preserves a range of research interests, including the use of advanced imaging in early cancer detection and understanding the aetiology and therapeutic options for patients who have gastrointestinal consequences of cancer treatment. 

She also remains involved in both single and multi centre clinical trials in the field of gastroenterology and endoscopy. One of the trials she was recently a co-investigator for was ‘DISCARD 2’, which is a trial that asessed how small polyps in the colon can be defined by imaging in routine practice and was published in a leading journal Gut.
