Current Use of EEN in Pre-Operative Optimisation in Crohn's Disease.

Despite the increasing array of medications available for the treatment of Crohn's disease and a focus on mucosal healing, approximately 35% of patients with Crohn's disease undergo bowel surgery at some stage. The importance of nutritional optimisation before Crohn's surgery is well-highlighted by surgical, nutritional, and gastroenterological societies with the aim of reducing complications and enhancing recovery. Surgical procedures are frequently undertaken when other treatment options have been unsuccessful, and, thus, patients may have lost weight and/or required steroids, and are therefore at higher risk of post-operative complications.
