Dr. Arjun Prakash – Gastroenterologist

I am a Consultant Gastroenterologist and Advanced Interventional Endoscopist in Milton Keynes providing care for adults (16 years and above). My practice combines a tailored assessment with evidence-based treatment, with a focus on continuity from initial consultation to follow-up, and beyond.

Following my MBBS, I completed an MD Internal Medicine, and higher speciality training in Gastroenterology. I chose advanced therapeutic endoscopy as my area of interest and completed a fellowship training in ERCP, EUS, luminal stent placements for benign and malignant disease, and feeding-tube placements. My training gathers experience from around the world, notably the Herlev Hospital, University of Copenhagen, a leading European centre for EUS.

I keep practice up to date with current American (AGA, ASGE), British (BSG, NICE) and European (ESGE) guidance. My endoscopic outcomes are audited every six months against the BSG and Joint Advisory Group (JAG) standards.

I lead the Endoscopic Ultrasound (EUS) service at Milton Keynes University Hospital, which I established in 2022, to improve decision-making in suspected pancreatic and biliary disease. I introduced EUS-guided fine-needle biopsy in Milton Keynes to aid early diagnosis of cancers and other disorders, allowing local access to these complex procedures but importantly, early cancer diagnosis.

I am UK JAG-accredited as an endoscopist and trainer in upper GI endoscopy, colonoscopy and ERCP. I am also an Educational Supervisor for Oxford Deanery registrars training them in Gastroenterology and Advanced Endoscopy. I also hold the position of Honorary Senior Clinical Lecturer at the University of Buckingham Medical School.

My research interests include early cancer diagnosis. Aside from multiple peer-reviewed publications, I am currently a Principal Investigator (PI) in the PANACEA trial and a co-PI from Milton Keynes in the VAPOR trial, studying breath tests for early cancer detection in partnership with Imperial College, London. I have also been the Trust lead for national audits, such as the National Upper GI Bleed Audits and the missed upper GI cancer audit.

My professional memberships include the Royal College of Physicians, the British Society of Gastroenterology and the UK & Ireland EUS Society, among others.

I see common gastrointestinal and liver conditions day to day, including:

– reflux and heartburn

– indigestion and dyspepsia

– bloating, IBS and abdominal pain

– rectal bleeding

– change in bowel habit, diarrhoea and constipation

– iron-deficiency anaemia

– swallowing difficulty (dysphagia)

– coeliac disease assessment and follow-up

– abnormal liver tests, NAFLD and viral hepatitis

– gallstones and biliary colic

– pancreatitis and jaundice

– chronic abdominal pain with unclear cause

My choice of Investigations and treatments are tailored to your clinical question but also your personal and social scenarios. Routinely, I offer gastroscopy, colonoscopy and flexible sigmoidoscopy when appropriate, and use EUS and ERCP when precise imaging or minimally invasive therapy will change management. Other advanced therapeutic work includes EMR for larger or pre-cancerous polyps, luminal stent placement and feeding-tube placement
