The problem of gastroesophageal reflux disease among bariatric patients is constantly growing. While bariatric surgery is the most effective method of treating obesity and related diseases, not all surgical procedures lead to improvement or resolution of gastroesophageal reflux disease. The search for the "ideal" surgical procedure for this group o...

Introduction Metabolic/bariatric surgery is the only proven treatment for type 2 diabetes mellitus (T2D) with curative intent. However, in a number of patients, the surgery is not effective or they may experience a relapse. Those patients can be offered re-do bariatric surgery (RBS). Purpose The study aimed to determine factors increasing the odds...

Introduction The type 2 diabetes (T2D) improvement rate in the elderly is high after bariatric and metabolic surgery, but not all patients achieve complete remission of disease. There are some predictors for T2D remission after bariatric surgery in patients of different ages, but there are few studies describing these factors in elderly patients. T...
