Personal profile

Mr Steve Warren is a laparoscopic general and colorectal surgeon.

He qualified in 1986 from the University of London, and early on in his surgical career he became interested in the laparoscopic approach to surgery recognizing that patients had less pain and recovered more quickly, usually with fewer complications. He first performed a laparoscopic cholecystectomy in March 1991, and so unusual was this approach at the time, that he appeared on the front page of the local newspaper! As a young Consultant, he won a National Scholarship to work and learn laparoscopic techniques at the prestigious Cleveland Clinic in USA for a 3 month sabbatical.

Since that time, he has applied his laparoscopic skills to a wide variety of surgical operations, both elective planned and emergencies, such that most of his surgeries are now performed laparoscopically, allowing increasingly operations to be completed as daycases. He has many Internationally published papers concerning new laparoscopic daycase operations, reducing pain in laparoscopic general surgical (eg all types of hernias, gallstone problems, emergency appendicitis) and colorectal resections, and enhanced recovery techniques to improve surgical care after laparoscopic removal of the bowel for cancers, complicated diverticular disease and inflammatory bowel conditions such as Crohn's disease. He has approximately 100 original publications. He also lectures and teaches new consultants from around the world, live demonstrating specialized laparoscopic techniques to International audiences.

His higher degree research in surgery, concerned the activity of the normal bowel and in patients with severe constipation/ loose motion and those with irritable bowel syndrome, and he retains an interest in treatment of IBS. He was awarded a Master of Surgery MS in surgery for this thesis in 1999 from the University of London. Mr Warren is Head of Department for Surgery at Barnet and Chase Farm NHS Hospitals and President of the North London Ileostomy Association.
