Abstract
<b><i>Background:</i></b> This review addresses the intricate spectrum of gastroesophageal reflux disease (GERD), a condition affecting 10–30% of the Western population. GERD is characterized by the backflow of gastric contents into the esophagus, causing typical and atypical symptoms. Its pathophysiology involves various factors such as hiatal hernia, esophageal motor disorders, and dietary triggers. The review explores the complexities of GERD spectrum, including nonerosive reflux disease (NERD), reflux hypersensitivity (RH), and functional heartburn (FH). <b><i>Summary:</i></b> The diagnostic process for GERD, based on the Lyon Consensus 2.0 criteria, encompasses clinical evaluation, endoscopy, and functional tests, including pH-impedance and wireless-pH monitoring. NERD, a significant subset of GERD, is defined by reflux symptoms and abnormal reflux burden without mucosal damage. RH, classified under functional esophageal disorders by Rome IV criteria, presents with typical esophageal symptoms associated with reflux but lacks of structural, inflammatory, or motor causes. FH is identified by heartburn with normal endoscopy, reflux testing, and esophageal manometry results. The management of RH and FH, focusing on reducing esophageal hypersensitivity, varies from standard GERD treatments. <b><i>Key Messages:</i></b> The review emphasizes the necessity of personalized treatment strategies due to the complexity and overlap of GERD subtypes. It highlights the importance of a multidisciplinary approach, involving gastroenterologists, psychologists, and other specialists, to improve patient outcomes and quality of life. The article underscores that understanding the distinctions and overlaps among NERD, RH, and FH is crucial for effective management, and the need for innovative approaches in diagnosis and treatment to address the unique challenges of each subtype.

Abstract
Laparoscopic fundoplication is the current surgical gold standard for the treatment of refractory gastroesophageal reflux disease (GERD). Magnetic sphincter augmentation (MSA) is a less invasive, standardized, and reversible option to restore competency of the lower esophageal sphincter. A comparative cohort study was conducted at a tertiary-care referral center on patients with typical GERD symptoms treated with systematic crural repair combined with Toupet fundoplication or MSA. Primary study outcome was decrease of Gastroesophageal Reflux Disease-Health Related Quality of Life (GERD-HRQL) score. Between January 2014 and December 2021, a total of 199 patients (60.3% female, median [Q1-Q3] age: 51.0 [40.0-61.0]) underwent MSA (n = 130) or Toupet fundoplication (n = 69). Operative time and hospital stay were significantly shorter in MSA patients (P < 0.0001). At a median follow-up of 12.0 [12.0-24.0] months, there was a statistically significant decrease of GERD-HRQL score in both patient groups (P = 0.001). The mean delta values did not significantly differ between groups (P = 0.7373). The incidence of severe gas bloating symptoms was similar in the two groups (P = 0.7604), but the rate of persistent postoperative dysphagia was greater in MSA patients (P = 0.0009). Six (8.7%) patients in the Toupet group had recurrent hiatal hernia requiring revisional surgery in one (1.4%). In the MSA group, eight (7.9%) patients necessitated through-the-scope balloon dilation for relief of dysphagia, and six patients had the device removed (4.6%) because of persistent dysphagia (n = 3), device disconnection (n = 1), persistent reflux (n = 1) or need of magnetic resonance (n = 1). Toupet and MSA procedures provide similar clinical outcomes, but MSA is associated with a greater risk of reoperation. Randomized clinical trials comparing fundoplication and MSA are eagerly awaited.

Schoppmann SF. Is magnetic sphincter augmentation indicated in patients with laryngopharyngeal reflux? Dis Esophagus 2023; 36:doad012. [PMID: 37317930 DOI: 10.1093/dote/doad012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Revised: 01/18/2023] [Indexed: 06/16/2023]
Abstract
Up to 30% of patients with gastroesophageal reflux disease (GERD) suffer from laryngopharyngeal reflux (LPR) with symptoms, as chronic cough, laryngitis, or asthma. Besides life-style modifications and medical acid suppression, laparoscopic fundoplication is an established treatment option. Treatment-related side effects after laparoscopic fundoplication have to be weighted against LPR symptom control in 30-85% of patients after surgery. Magnetic sphincter augmentation (MSA) is described as an effective alternative to fundoplication for surgical treatment of GERD. However, evidence on the efficacy of MSA in patients with LPR is very limited. Preliminary data on the results of MSA treating LPR symptoms in patients with acid and weakly acid reflux are promising; showing comparable results to laparoscopic fundoplication by providing the potential of decrease side effects.

Abstract
Summary
Background
The burden of gastroesophageal reflux disease (GERD) is high, with up to 30% of the Western population reporting reflux-related symptoms with or without hiatal hernia. Magnetic sphincter augmentation (MSA) is a standardized laparoscopic procedure for patients who are dissatisfied with medical therapy and for those with early-stage disease who would not usually be considered ideal candidates for fundoplication. The MSA device is manufactured in different sizes and is designed to augment the physiologic barrier to reflux by magnetic force.
Methods
An extensive scoping review was performed to provide a map of current evidence with respect to MSA, to identify gaps in knowledge, and to make recommendations for future research. All the authors contributed to the literature search in PubMed and Web of Science and contributed to summarizing the evidence.
Results
Magnetic sphincter augmentation, especially in combination with crural repair, is effective in reducing GERD symptoms, proton pump inhibitor use, and esophageal acid exposure, and in improving patients’ quality of life. Safety issues such as device erosion or migration have been rare and not associated with mortality. The MSA device can be removed laparoscopically if necessary, thereby preserving the option of fundoplication or other therapies in the future. Contraindication to scanning in high-power Tesla magnetic resonance systems remains a potential limitation of the MSA procedure. High-resolution manometry and functional lumen imaging probes appear to be promising tools to predict procedural outcomes by improving reflux control and reducing the incidence of dysphagia.
Conclusion
A consensus on acquisition and interpretation of high-resolution manometry and impedance planimetry data is needed to gain better understanding of physiology, to improve patient selection, and to pave the way for a personalized surgical approach in antireflux surgery.

Abstract
With the advent of high-resolution esophageal manometry, it is recognized that the antireflux barrier receives a contribution from both the lower esophageal sphincter (intrinsic sphincter) and the muscle of the crural diaphragm (extrinsic sphincter). Further, an increased intra-abdominal pressure is a major force responsible for an adaptive response of a competent sphincter or the disruption of the esophagogastric junction resulting in gastroesophageal reflux, especially in the presence of a hiatal hernia. This review describes how the pressure dynamics in the lower esophageal sphincter were discovered and measured over time and how this has influenced the development of antireflux surgery.
