De novo gastroesophageal reflux disease esophageal surgery in bariatrics: a literature review and analysis of the current treatment options

With the exponential increase of worldwide obesity, the number of bariatric surgery (BaS) procedures have equally risen. The surgical management of obesity has been widely established as the standard of care for sustained weight reduction, resolution, and improvement of associated comorbidities. However, BaS itself can have postoperative deleterious effects, including de novo gastroesophageal reflux disease (GERD) and upper gastrointestinal motility disorders. The modified anatomy resulting from BaS, due to either a restrictive or hypoabsorptive component, gives this disorder a multifactorial etiology. The overall management of de novo GERD should focus on three primordial approaches: Non-surgical, endoluminal, and surgical. Even in the absence of de novo GERD following primary or secondary BaS, said disorder should be closely monitored and therapy should be catered in a case-by-case approach. Consequently, treatment strategies have been developed on this principle as to adequately resolve de novo GERD. Despite the presence of multiple and suitable treatment modalities, the operating surgeon should perform them in the best interest of the patient. Short-, medium-, and long-term outcomes should be taken into consideration prior to proceed with any type of preferred management option. This article herein presents an update on the surgical management of de novo GERD following BaS and current practical innovations.

Automated summary

With the rise of global obesity, the number of bariatric surgery procedures is increasing. However, bariatric surgery can have postoperative effects such as de novo gastroesophageal reflux disease and upper gastrointestinal motility disorders. Management of de novo GERD should focus on non-surgical, endoluminal, and surgical approaches, with treatment tailored to individual cases.
