This study aims to help patients recover faster after colorectal cancer surgery by using wearable devices to monitor early movement.

Patients will wear a lightweight wristband that tracks heart rate, sleep, and daily steps after surgery. The goal is to find out if early walking can reduce the chances of complications, shorten hospital stays, and lower medical costs.

Participants will start wearing the device after surgery and continue for about 7 days or until they leave the hospital. During this time, they will also fill out a simple daily observation form. Participation is voluntary, and patients can withdraw at any time without affecting their care.

The study hopes to provide new ways to improve recovery and offer better support to patients after colorectal surgery.

Inclusion Criteria:

1. Patients undergoing minimally invasive colorectal tumor resection.
2. Aged 20 to 85 years.
3. ECOG score 0-2.
4. Clear consciousness and ability to communicate in Mandarin or Taiwanese (or via family translation).
5. Informed consent provided by the patient or family.

Exclusion Criteria:

1. Patients with acute/chronic psychiatric disorders or cognitive impairment.
2. Patients undergoing traditional open or local resection surgeries.

Adults aged 20 to 85 years diagnosed with colorectal cancer who underwent minimally invasive surgery at a medical center. Patients must be able to communicate in Mandarin or Taiwanese and provide informed consent.

Individual Participant Data (IPD) will not be shared due to the need to protect patient privacy and confidentiality. Additionally, there are no current plans for secondary analysis or collaboration with external researchers.
