Study Arms:
- Verum (Type: EXPERIMENTAL): Patients will receive 2 encapsulated capsules containing aprepitant 80mg to be ingested with a sip of water 2 hours before surgery and 24 hours after surgery. Surgery will follow our hospital enhanced recovery after surgery (ERAS) standard (general anaesthesia using volatile anaesthetics, intravenous dexamethasone 8mg and ondansetron 4mg for PONV prophylaxis).
- Placebo (Type: PLACEBO_COMPARATOR): Patients will receive similar looking encapsulated capsules containing only placebo to be ingested with a sip of water 2 hours before surgery and 24 hours after surgery. Surgical and anaesthetic procedures are identical to the verum arm.

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