The goal of this trial is to examine long-term effects of laparoscopic gastric bypass (LRYGB) and sleeve gastrectomy (LSG) on oesophageal symptoms and disease, including the presence of Barrett oesophagus ≥ 5 years post-surgery.
Bariatric surgery shows impressive results in terms of weight loss and resolution of comorbidities. Still, there are questions as to the frequency of long-term adverse effects: the prevalence and causes of post-operative swallowing disorders and reflux disease are uncertain. Recently, independent study groups described a high incidence of Barrett oesophagus post LSG. Additional research is urgently needed. The goal of this trial is to examine long-term effects of laparoscopic gastric bypass (LRYGB) and sleeve gastrectomy (LSG) on oesophageal symptoms and disease, including the presence of Barrett oesophagus ≥ 5 years post-surgery.
