Mr Stephen Brennan

Stephen Brennan is a Consultant General & Gastrointestinal surgeon with special interests in Upper GI & Laparoscopic surgery. He has worked for the NHS for over 20 years including 12 years as a Consultant. He left a substantive NHS Consultant post to go full-time into private practice as it was the only way he could deliver safe and effective healthcare. He has extensive experience in Gallbladder surgery having recently performed Shirley Oaks Hospital's first emergency acute gallbladder removal with keyhole surgery. He performs Laparoscopic Anti-reflux surgery independently and approximately 150 Laparoscopic Cholecystectomies (Gallbladder removal) per year. He repairs all kinds of abdominal wall hernias including the complex variety by both open & Laparoscopic approaches including the Component Separation Technique (CST).

He is originally from Dublin having trained in Scotland with also brief periods in Melbourne and South Africa for additional training.  He worked at the world renowned centre of excellence at the MATTU Centre at Guildford. Mr Brennan’s previous roles include MRCS examination tutor with the Royal College of Surgeons and is a fully trained advanced trauma life support instructor.  His particular area of expertise is in keyhole removal of gall bladders for which he has a very low complication rate with a less than 1% conversion rate to open procedure and a 0% bile duct injury rate. 

In a recent consultant appraisal, his colleagues have described him thus “Stephen is a very approachable and excellent laparoscopic surgeon”.  “Great colleague”. “One of the very best general surgeons and clinicians I have seen and worked with. I would let him operate on myself and my family”.

Outside of work Mr Brennan has a wide range of skills including holding a private pilot’s licence, he has a black belt in American Kenpo karate, has completed the London triathlon and is currently training for an Iron Man competition.  In his spare time, he shares these hobbies with his young daughter Caitlin.
