Gastroesophageal reflux disease (GERD) is one of the most common disorders in medical practice. A number of guidelines and recommendations for the diagnosis and management of GERD have been published in different countries, but a Brazilian accepted directive by the standards of evidence-based medicine is still lacking. As such, the aim of the Brazilian GERD Consensus Group was to develop guidelines for the diagnosis and management of GERD, strictly using evidence-based medicine methodology that could be clinically used by primary care physicians and specialists and would encompass the needs of physicians, investigators, insurance and regulatory bodies...

Gastro-esophageal reflux disease is a troublesome disease for many patients, severely affecting their quality of life. Choice of treatment depends on a combination of patient characteristics and preferences, esophageal motility and damage of reflux, symptom severity and symptom correlation to acid reflux and physician preferences. Success of treatment depends on tailoring treatment modalities to the individual patient and adequate selection of treatment choice. PubMed, Embase, The Cochrane Database of Systematic Reviews, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) were searched for systematic reviews with an abstract, publication date within the last five years, in humans only, on key terms (laparosc* OR laparoscopy*) AND (fundoplication OR reflux* OR GORD OR GERD OR nissen OR toupet) NOT (achal* OR pediat*)...

BACKGROUND: Some patients with typical (heartburn/regurgitation) symptoms of gastroesophageal reflux disease (GERD) are refractory to proton pump inhibitor (PPI) therapy. Impedance-pH monitoring can identify PPI-refractory patients who could benefit from laparoscopic fundoplication, but outcome data are scarce. We aimed to assess whether PPI-refractory GERD as diagnosed by impedance-pH monitoring can be cured by laparoscopic fundoplication. METHODS: Forty-four consecutive GERD patients with heartburn/regurgitation refractory to high-dose PPI therapy entered a 3-year outcome assessment following robot-assisted laparoscopic fundoplication...

BACKGROUND: Nissen fundoplication is a well-established treatment for gastroesophageal reflux disease (GERD) with a high success rate and a long-lasting effect. However, the literature reports that a persistent, small group of patients is not fully satisfied with the outcome. Identifying this patient group preoperatively would prevent disappointment for both patients and surgeon. This has proven difficult since dissatisfaction was related to nondisease-related factors instead of typical symptoms of GERD or the objective findings of investigations...

BACKGROUND: Laparoscopic magnetic sphincter augmentation (MSA) with the LINX device is a promising new therapy for the treatment of gastroesophageal reflux disease (GERD). Initial studies have demonstrated MSA to be safe and effective. However, no direct comparison between MSA and laparoscopic Nissen fundoplication (LNF), the gold standard surgical therapy for GERD, has been performed. METHODS: A single institution, case-control study was conducted of MSA performed from 2012 to 2013 and a cohort of LNF matched for age, gender, and hiatal hernia size...
