Subjects will undergo an upper endoscopy with EndoFLIP before sleeve gastrectomy to measure parameters from endoscopy and EndoFLIP device to develop a prediction model for post-operative gastroesophageal reflux disease. Subjects will undergo a repeat upper endoscopy with EndoFLIP at 6 months if an upper endoscopy is clinically indicated after surgery and complete questionnaires during follow-ups up to 5 years.
Researchers are trying to identify predictors for gastroesophageal reflux disease after sleeve gastrectomy.
