A new prediction model helps surgeons estimate patient recovery time after gastrointestinal cancer surgery, improving preoperative counseling.

• Among 91,270 patients, the median days at home within 90 days post-surgery was 82 (IQR 77-85).
• The model achieved strong accuracy (mean absolute error 8.67) and good calibration.

This tool enhances shared decision-making by providing tailored recovery expectations based on preoperative factors.
