IBD and Ileoanal Pouch Surgery Centre


Our Inflammatory Bowel Disease (IBD) and Ileoanal Pouch Surgery Centre provides all patients with a multidisciplinary approach, comprising IBD surgeons, gastroenterologists, radiologists, dietitians, and specialised nurses with high-level expertise in treatment of Crohn’s disease and ulcerative colitis. 

Our Trust is a tertiary referral centre for Crohn’s disease and ileoanal pouch surgery and boasts of a high-volume service in minimally invasive surgery for primary and recurrent Crohn’s disease, Kono-S anastomosis technique, fistulating and perianal Crohn’s disease. We have a high-volume practice in ileoanal “J-Pouch” surgery, performing primary and revisional ileoanal pouch surgery, and pouch excision. 

The Ileoanal J-Pouch clinic is a multidisciplinary service offered to patients who have an ileoanal pouch or are considering having surgery. A dedicated pathway for these patients was developed at our J-Pouch one-stop clinic involving an endoscopic assessment of the pouch (pouchoscopy) and same-day meeting with our team of colorectal surgeons, gastroenterologists, IBD and stoma/pouch nurses. Our service also provides the chance for peer-to-peer counselling thanks to a group of patients who previously had pouch surgery under our care and agreed to volunteer and share their precious experience and perspective.

In the dedicated J-Pouch clinic we evaluate conditions such as pouchitis, pouch dysfunction, pouch-anal and pouch-vaginal fistulae, increased bowel frequency, primary ileoanal pouch and redo pouch surgery, and surgical treatment of ulcerative colitis. The excellent care provided by the IBD and and Ileoanal Pouch Surgery Centre has been awarded nationally by the British Society of Gastroenterology.

Our IBD centre has florid research and education activity, hosting national courses and leading on NIHR and multi-centre studies. We also collaborate and place our experience at the disposal of patients coming from other units, such as paediatric colorectal or endometriosis units, joining our colleagues to treat complex paediatric and endometriosis cases.

Consultant surgeon Mr Valerio Celentano  received the Service Development Award from the British Society of Gastroenterology during the BSG annual conference in Birmingham in 2022. This is a prestigious award that acknowledges the high volume and high-quality care delivered by our Inflammatory Bowel Disease (IBD) team. The award recognises the multidisciplinary patient-centred approach to ileoanal pouch surgery which, at our Trust, involves collaboration among colorectal surgeons, gastroenterologists, stoma nurses, dietitians, radiologists, IBD nurses and paediatric surgeons. Our surgical team was awarded in Birmingham for the excellent outcomes of our high-volume service, with 24 procedures performed in an 18-month study period. Thank you also to Melanie Jerome in the stoma care team, who has relentlessly supported our patients and service.
