Prehabilitation to Enhance Preoperative Function in Elderly Undergoing Abdominal Malignancy Surgery

Starting soon

Conditions studied: Prehabilitation, Functional Capacity

In brief

The goal of this observational study is to evaluate the effectiveness of the multimodal prehabilitation program at the Siriraj Integrated Preoperative and Prehabilitation Center (SiPAP) on improving preoperative walking capacity and functional status in patients undergoing elective intraabdominal cancer surgery. The main question it aims to answer is: \- Does the prehabilitation program lead to a significant change in 6-minute walk distance (6MWD) at preoperative admission as compared to at baseline assessment? Participants will receive the structured multimodal prehabilitation program, which represents the standard of care for patients in the ERAS protocol at the study site. Outcomes will be measured at preoperative admission and at 1 and 3 months after surgery.

Who can join

Age: 60 and older, up to 90. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Diagnosed with intraabdominal malignancy (e.g., colorectal, esophageal, gastric, pancreatic, hepatic, biliary tract, urinary bladder, or endometrial malignancies).
• Schedules for elective major surgery and formally enrollment in the ERAS program at Siriraj Hospital. (at Siriraj Hospital, patients scheduled for pre-specific elective major surgeries are enrolled into the ERAS program as individual hospital protocols for each ERAS module. All patients are informed about the ERAS program by their surgical team.)
• Referred to the SiPAP center for prehabilitation in accordance with the ERAS preoperative protocol, with a minimum preoperative time of 14 days before the scheduled surgery date.
• Able to understand the study protocol and provide written informed consent.

You may not qualify if…

• Have emergency surgery
• Reschedule the surgery for an earlier date, allowing less than 14 days for prehabilitation.
• Severe cardiopulmonary or musculoskeletal conditions that contraindicate exercise (e.g., unstable angina, decompensated heart failure, severe COPD, or orthopedic disability).
• Cognitive impairment or psychiatric illness precluding participation in prehabilitation.
• Refusal to participate.
• Inability to comply with the protocol.
