Bariatric Surgery and Gut Microbiota Changes Over Time

The goal of this observational study is to learn how bariatric surgery affects gut bacteria and gut-related metabolic products over time in adults with obesity. The study includes adults aged 18 to 65 years who are undergoing Roux-en-Y gastric bypass (RYGB) surgery, as well as adults with obesity treated with diet alone and healthy normal-weight adults. The main questions it aims to answer are: How does bariatric surgery change the composition and diversity of gut bacteria over time? How are these changes related to weight loss and improvement of obesity-related health conditions? Researchers will compare people undergoing bariatric surgery with people with obesity treated with diet alone and with healthy normal-weight individuals to see if surgery leads to specific changes in gut bacteria and stool metabolites that are linked to better clinical outcomes. Participants will: Provide stool samples at scheduled time points over 12 months Provide blood samples and undergo routine clinical assessments Take part in follow-up visits to monitor weight, metabolic health, and gastrointestinal symptoms

Intravenous Tranexamic Acid

Tranexamic acid is a promising option for minimizing blood loss in high-risk bariatric surgery patients, particularly in those with obesity, diabetes, and other comorbidities. When used appropriately, TXA can reduce the need for blood transfusions, maintain hemodynamic stability, and lower the incidence of complications related to blood loss.

Modifications to Gastric Sleeve: Implications for GRED and Quality of Life

This is a prospective randomized clinical trial evaluating the impact of antrum and fundus calibration during laparoscopic vertical gastrectomy (VG) on postoperative gastroesophageal reflux disease (GERD), quality of life, and surgical costs. Eligible participants are adults with morbid obesity (BMI ≥35 kg/m²) undergoing LSG. Patients are randomized into four groups based on whether antral and/or fundal calibration is performed. Primary outcomes include the incidence of de novo GERD at 12 months. Secondary outcomes include postoperative quality of life, vomiting , surgical complications, weight loss, and operative costs. The study aims to optimize the LSG technique by identifying anatomical modifications that minimize GERD while improving clinical outcomes
