The goal of this clinical trial research study is to evaluate the impact of preoperative oral immunonutrition (IN) on post-operative complications in patients undergoing a cystectomy. As a secondary focus, this study will aim to develop a signature that would identify patients that would benefit the most from IN. This is a multicentric (Swiss: N=3), prospective, controlled, pragmatic, parallel-group comparative study with block randomization stratified by centers.

Eligibility | Inclusion Criteria: - Patient undergoing open cystectomy (for all reasons) - Age =18 years - Ability and willingness to provide informed consent documented by signature Exclusion Criteria: - Contraindications to IN, e.g. known hypersensitivity or allergy to lactose, fish oil or soy lecithin - Severe diarrhoea requiring medical attention - Current treatment with any immunosuppressive drug - In standard practice, pregnant or lactating women are systematically rejected by the surgeon for this surgical procedure. Furthermore, during the pre-surgical anaesthesia consultation, the eligibility of each patient for anaesthesia will be assessed according to the usual criteria and recommendations of the anaesthesia service of the CHUV - Other clinically significant concomitant disease affecting immunity (e.g., severe renal failure, HIV, SLE, transplant recipient, ...) - Inability to follow the procedures of the study, e.g. due psychological disorders, dementia, etc. - Participation in another study with investigational drug within the 30 days preceding and during the present study - Previous enrolment into the current study - Use of IN independently of the study - Enrolment of the investigator, his/her family members, employees and other dependent persons - Emergency procedure (less than 7 days between screening and surgery) |
