[Gastroesophageal reflux after sleeve gastrectomy : a clinical challenge].

Although sleeve gastrectomy is a commonly performed bariatric procedure, it is well recognized as being associated with an increased risk of gastroesophageal reflux disease. This multifactorial phenomenon involves anatomical, functional, and hormonal alterations that can compromise the antireflux barrier. A thorough preoperative assessment is crucial for identifying at-risk patients and minimizing postoperative complications. Initial management relies on lifestyle and dietary modifications combined with medical therapy. However, refractory cases often require surgical revision. Conversion to Roux-en-Y gastric bypass, performed in Switzerland exclusively in specialized reference centers, remains the most effective strategy to control symptoms while maintaining the metabolic benefits of bariatric surgery.
