- Time Perspective: None
- Masking: NONE
- Phase: PHASE4
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* regular radical cystectomy~Exclusion Criteria:~* preoperative contra-indications for enteral nutrition (EN): intestinal obstruction, malabsorption, multiple high-output fistula and intestinal ischemia

- Gender: ALL
- Minimum Age: 18 Years

Study Arms:
- Control group (Type: ACTIVE_COMPARATOR): Subjects enrolled in this arm will undergo usual medical and pharmaceutical care. In this group, parenteral nutrition (Oliclinomel N7) is part of the routine postoperative care program.
- Oral Nutrition Protocol (ONP) group (Type: EXPERIMENTAL): Oral intake was increased progressively with oral fluids and easily digestible food, independent of bowel movements. The corresponding energy content from the meals and oral fluids were calculated. Fortimel Jucy®, 200 ml containing 300 kcal, was used as the formulary energy sip. Extra fluids, up to two liter per day, were given intravenously, at the discretion of the treating physician. If the patient tolerated the ONP well, the oral intake was considered equal in terms of calories as the corresponding oral meal in the ONP. From the sixth day, the patient was allowed to eat at will. Only if oral intake remained insufficient after 5 days, which was left to the opinion of the treating physician, PN could be initiated in this group.

Based on this trial design, predict the completion outcome and termination type (if applicable).
