Endoscopic practice

In_ProcedureAs of 2019, I have performed about 8000 gastroscopies, 3500 flexible sigmoidoscopies and 6000 colonoscopies; inserted approximately 200 gastrostomy tubes; and reviewed ≈ 1000 capsule endoscopies. Auditing my colonoscopy practice in summer/autumn 2011 and 2015, I intubated the caecum in >99% (n=163/200) detecting polyps in 28%/31%. My known life-time complication rate is low (3 admissions for bleeds; 1 perforation requiring surgery following attempted endoscopic resection of a cancer). I have promoted the use of water exchange colonoscopy and water immersion polypectomy, which increases patient comfort and ensures colon cleanliness.


Clinical practice

I spend about 25% of my time working for the NHS, and the rest in private and academic practice. In the NHS I undertake endoscopy lists and clinics, looking after patients with a wide range of conditions (including Crohn’s disease and colitis; IBS; peptic ulcer disease; celiac disease; chronic diarrhoea; constipation; nutrition).
The result from my 360-degree NHS patient feedback (2013, and replicated in 2017) was excellent, rated 5.8 by all patients (scale 1-6, where 5 is “very good” and 6 is “excellent”). I have been an active teacher and regularly examined for the Royal College of Physicians “PACES” exam.



I lead the UK Twin and Multiplex Inflammatory Bowel Disease Registry, with charitable grant funding of £1 million awarded in 2012. Biological samples have been collected from 100 IBD twin-pairs, and collaborative research programs have been set up with Professor Jack Satsangi (Edinburgh), Professor Vibeke Andersen (Denmark), Professor Julian Marchesi (Imperial College) and Professor Siew Ng (Hong Kong).

I developed an algorithmic educational resource for the European Crohn’s and Colitis Organisation (ECCO), called the ECCO e-Guide. Since its release in 2016, this visualisation of their guidelines has been reviewed by more than 20,000 healthcare professionals worldwide. For this work, I was awarded the ECCO Mark of Merit, an accolade that is only provided to 3-5 individuals annually.

As chairman of the ECCO Guidelines Committee during 2015/2016, I organised and was lead author for the Third European Consensus Guideline on Ulcerative Colitis and the First European Consensus Guideline on Extraintestinal Manifestations of Inflammatory Bowel Disease.

I have been a principal investigator or co-investigator for several clinical trials since 2006. My research contributions have been undertaken entirely freely, as I have a full time clinical role; as Benjamin Franklin (1706-1790) said, “If you want something done, ask a busy person”.

Finally, I regularly review papers for Inflammatory Bowel Disease, GUT, Alimentary Pharmacology & Therapeutics, Frontline Gastroenterology, Journal of Crohn’s and Colitis, and the British Medical Journal.

As of 2019 I am leading an exciting project, called, to provide healthcare advice to the poorest people in the world. This is a MedTech venture- watch this space!
