Filter by:In this study, it is aimed to evaluate whether the addition of prebiotics to patients' post-operative diets increases Roux-en-Y Gastric Bypass surgery effects. Half of the participants were randomized prebiotic with conventional yogurt, while the other half were randomized only conventional yogurt as a snack
Obesity and related metabolic diseases have become a chronic disease that is a threat to human health. Bariatric surgery can effectively and long-term reduce excess body weight and relieve related metabolic diseases, including type 2 diabetes. Laparoscopic gastric bypass surgery and laparoscopic sleeve gastrectomy are commonly used in bariatric surgery. Laparoscopic sleeve gastrectomy due to simple operation, good weight loss, and metabolic disease control effect, which is more widely used. However, there are several studies that show an increased chance of gastroesophageal reflux disease after laparoscopic sleeve gastrectomy. Long-term gastroesophageal reflux may lead to Barrett's esophagus or esophageal cancer. Nowadays, the cause of gastroesophageal reflux disease after sleeve gastrectomy is not clear and precautionary measures are not precise. In this study, prospective randomized controlled trials were conducted to explore the possible causes of gastroesophageal reflux after sleeve gastrectomy and to explore ways to prevent gastroesophageal reflux disease after sleeve gastrectomy.
Prospective association study to analyse patients' outcome after bariatric surgery. Outcome comprises postoperative pain, analgesia, postoperative side-effects, long-lasting pain, patients' impairment in daily living.
The therapeutic problem of obesity is weight control, a major difficulty, involving a significant change in eating behavior. A number of studies show that there are many factors of resistance to weight loss whether they are physiological, genetic, environmental pressure related, or psychological and behavioral. For some patients, the surgical approach seems the best alternative. Indeed, bariatric surgery is an effective therapeutic weapon in patients with morbid obesity. However, it has been shown that approximately 25% of patients are failing at two years of this surgery (Reinhold's index). Some of the failed subjects may benefit from surgical revision. As for the others, no intervention is currently proposed to them. Studies have shown that the psychological profile of patients who are candidates for bariatric surgery is predominantly impulsive, very anxious with a tendency to depression. The stress level of these patients would be important, and they would have low self-esteem. This study hypothesize that, in these patients, the establishment of hypnotherapeutic management associated with the usual dietary monitoring could modify eating habits thus promoting weight loss and an improvement in self-esteem , stress and anxiety compared to dietary monitoring alone.
The purpose of the study is to test how dietary habit interventions affect patients weight loss outcomes after bariatric surgery.
Gastric bypass with omega loop technic (OLGB) seems to be as effective as gastric bypass roux-en-Y (RYGB the reference) for the management of obesity and type 2 diabetes, but with less early surgical complications and more undernutrition in long terms. This study aims to explore the profile of secretion of entero-insular hormone after a meal test in OLGB patient vs RYGB to understand the mechanisms of the improvement of type 2 diabetes after OLGB. Secondary objectives are to better understand the absorptive function of the gut after a gastric bypass, to understand why is there more undernutrition in long term after OLGB than after RYGB.
The aim of this study is to investigate the effect of using new app-based technology to increase the level of physical activity, compared to conventional postoperative information given to patients undergoing bariatric surgery. The hypothesis is that the intervention, i.e. using the new technology, will have a greater positive effect on levels of physical activity and outcomes of weight loss than conventional postoperative information.
The purpose of the study is to evaluate how dietary habits in the post-surgical year impact outcomes of bariatric surgery.
Background: There is a lack of evidence on whether maternal nutritional deficiencies after Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) affect fetal development. The investigators hypothesis is that SG could induce nutritional deficiencies during pregnancy, as RYGB does, because of food restriction. These nutritional deficiencies may alter fetal growth. Methods: Women with singleton pregnancies who had at least one nutritional evaluation during pregnancy in our institution between 2006 and 2017 were included. The investigators evaluated nutritional deficiencies according to standard and pregnancy-specific norms. They have planned to study the relationships between these parameters and fetal growth. Objectives: To compare maternal nutritional parameters and neonatal outcomes after RYGB and SG and to assess the impact of nutritional alterations on fetal growth.
The purpose of the study is to compare dietary habits after bariatric surgery in patients with poor weight loss versus good weight loss outcomes.
