Changes in Respiratory Function and Chest Wall Movement Following Oesophagectomy

What this Trial Is About

Researchers are investigating changes in respiratory function and chest wall movement in people who have undergone esophagectomy, a surgery to remove the esophagus, often due to esophageal cancer. The study includes both healthy volunteers and patients who had open esophageal surgery more than one year ago. The goal is to understand how chest wall movement relates to lung capacity and to explore the use of new measurement technologies after surgery. Participants will have chest wall movement measured using a 3D optical motion capture system with small reflective markers and wearable inertial measurement units placed on their chest. Measurements will be taken during various breathing patterns and while using an incentive spirometer, a device that helps assess lung function. The study involves 40 healthy volunteers and 60 patients who had open surgery. Clinical data including lung function tests and health-related quality of life questionnaires will also be collected. Each participant will undergo one assessment session lasting about 60 minutes. During this time, researchers will collect data on chest wall movement, lung function, and quality of life. The study aims to verify the reliability and patient acceptance of the wearable systems, assess differences between surgical approaches, and inform the development of tailored physiotherapy to improve respiratory function. The findings could help optimize recovery for patients after major esophageal surgery.
