Research summary
Oesophagogastric cancer surgery (surgery of the food pipe and stomach) can put a lot of stress on an individual’s body both during and after the operation. The body’s response to these operations determines the overall outcomes, risk of complications and post-operative recovery. An individual’s fitness prior to oesophagogastric cancer surgery can help clinicians better identify whether a person is likely to develop unwanted complications after an operation. By understanding how someone may perform after surgery, their recovery process and the risk of complications may be more readily anticipated.
For this reason, the standard of care for these patients is to undergo Cardiopulmonary exercise testing (CPET). CPET is a test used to check heart and lung function and can provide valuable information to clinicians on how an individual’s body may react to the stress of surgery. Patients are asked to walk on a treadmill while a healthcare professional measures their heart function and oxygen levels. The limitations with this are that it is a one-off test in a highly controlled, simulated environment.
In recent years, the use of wearable devices such as heart rate monitors are able to capture vast amounts of information on physical activity and heart rhythm in the comfort of a patient’s home environment, thereby capturing more realistic information about their daily activities. Wearable devices are easy to use and capture real-time information that is more reflective of an individual’s lifestyle.
In this study, we aim to compare wearable devices to CPET before surgery in its accuracy in predicting how well individuals perform after major abdominal cancer surgery.REC name
