Anti-reflux surgery vs. bariatric surgery as anti-GERD and hiatal hernia treatment in obese patient. New surgical proposals.

The persistence of obesity favors the failure of the Fundoplication (FP) in the treatment of Gastroesophageal Reflux (GER). However, the weight loss obtained with the performance of a Gastric Bypass (GBP) allows a good resolution of symptoms, without increasing the incidence of postoperative complications. All of this leads us to consider that while FP is the indication in patients with BMI < 30, in those patients with BMI > 35, GBP appears to be the procedure of choice. But there is still no position in the case of patients with a BMI between 30 and 35, although we must take into account that an increase in GER recurrence has been described after FP in patients with a BMI > 30. Although Sleeve Gastrectomy (SG) is one of the most frequently used bariatric procedures in recent years, its association with a high rate of postoperative GER has led several authors to propose its performance associated with an anti-reflux procedure in patients with GER symptoms. Likewise, if the existence of an Hiatal Hernia is verified, it must be treated by hiatoplasty, both during the performance of a GBP and a SG. This simultaneous treatment is not associated with an increase in complications.
