Mr Pellen's clinical practice covers advanced keyhole (laparoscopic) and open surgery of the abdomen including weight loss (bariatric) surgery, anti-relux and hiatus hernia surgery, gallstone surgery, hernia surgery and diagnostic endoscopy.
Mr Pellen's aim is to be a patient-focused surgeon, recommending and providing the very highest standard of surgical treatment options. Mr Pellen has sought to refine his expertise in the most advanced, evidence based and up to date procedures available.
To this end his training and research has been undertaken in several specialist centres of excellence including:
- Northumbria Upper GI Team of Surgeons Unit
- AZ Sint Jan Hospital (Bruges, Belgium) with Dr Bruno Dillemans (one of Europe's leading weight loss surgeons and Secretary General of the Belgian Obesity Surgeons)
- Groote Schuur (Cape Town, South Africa)
- St James University Hospital and Castle Hill Hospital
Mr Pellen's work has been published in the international and national peer-reviewed scientific literature and he is an active trainer on courses for Management of Trauma of the Injured (Advanced Trauma Life Support) and the Royal College of Surgeons keyhole surgery training courses nationally.
