Development and Validation of a Disease-Specific Instrument to Measure Diet-Targeted Quality of Life for Postoperative Patients with Esophagogastric Cancer

Background Patients who have undergone esophagectomy or gastrectomy have certain dietary limitations because of changes to the alimentary tract. This study attempted to develop a psychometric scale, named “Esophago-Gastric surgery and Quality of Dietary life (EGQ-D),” for assessment of impact of upper gastrointestinal surgery on diet-targeted quality of life.
