Exclusive enteral nutrition (EEN) has proven to be a highly effective treatment option in inducing remission in active Crohn’s disease (CD) in the paediatric population. In adults with CD, the results of meta-analyses demonstrated that therapy with corticosteroids was more effective in comparison with EEN. The most important limitation of the success of EEN treatment is patients’ compliance. Exclusivity of enteral nutrition and its substantial impact on the quality of life are the main reasons why EEN is not acceptable to many patients. Therefore, the treatment with partial enteral nutrition (PEN), where patients are allowed to eat some ordinary food besides enteral formulas, is becoming an important treatment option, not only in inducing, but also in maintaining remission in CD. However, strong evidence on the efficacy of PEN for induction and maintenance of CD remission is still lacking. Due to the excellent safety profile of the treatment with enteral nutrition in comparison with other treatment modalities, further well-designed, randomised, controlled studies are necessary to elucidate the exact role of PEN in inducing and maintaining of remission in CD patients. Herein, the most relevant studies on the efficacy and the role of PEN in active and quiescent CD are reviewed.
