  • It's world IBD Day tomorrow. So much has changed since I was diagnosed. I am forever grateful to Chris Hawkey, IBD Royal London, Al Windsor and many others who have kept me going to reach my goal of becoming a Consultant Gastroenterologist looking after IBD patients.

  • He is the full package, an exceptionally gifted surgeon and a clear leader in a very complicated, niche area of IBD surgery

  • His specialty area is abdominal catastrophes in Crohn’s — when things go spectacularly wrong sometimes as a result of disease but also as a result of complications from previous surgery. You can sometimes see the gut through a hole in the abdomen with these patients — he salvages them.

  • He is thoughtful and careful and has the incredible quality of being a human being first and foremost — patients love him

  • They will be on intravenous feeding for months but he will reconstruct the bowel and abdominal wall together with a plastic surgeon - demanding six or seven-hour procedures.


His Approach to Surgical Care

Alastair Windsor’s surgical ethos is based around working in and leading a dedicated surgical teams. As a pioneer of enhanced surgical recovery in the UK he has adapted much of this surgical approach to his care of patients in the private sector.

He is a highly trained colorectal surgeon having been through UK surgical training in addition to the sitting a higher degree for surgical research in the US. He spent 9 years as Consultant Surgeon at the world-famous St Mark’s Hospital and then moved with colleagues to set up an equally renowned colorectal unit at University College London Hospitals where he remains the senior colorectal surgeon.

Mr Windsor believes firmly, in a team-based approach to care. Within London Digestive Surgery he works very closely with Mr Ed Wescott a colleague and Consultant Colorectal Surgeon at Guys and St Thomas Hospital. The two surgeons operate together (at no extra cost) they care for the in patients together and provided on call cover for urgent and emergency problems. Mr Windsor believes this comprehensive approach provides the best possible care for his patients. He has forged a similar team approach to the surgical management of complex endometriosis with Mr Alfred Cutner, Consultant Gynaecological with joint care and operating at King Edward VII Hospital, London.
