Antireflux mucosal intervention (ARMI) procedures for refractory gastroesophageal reflux disease: a systematic review and meta-analysis.

ABSTRACT:

Background

Endoscopic treatments are increasingly being offered for refractory gastroesophageal reflux disease (GERD). Three procedures have similar concepts and techniques: antireflux mucosectomy (ARMS), antireflux mucosal ablation (ARMA), and antireflux band ligation (ARBL); we have collectively termed them antireflux mucosal intervention (ARMI). Here, we systematically reviewed the clinical outcomes and technical aspects.

Methods

The PubMed, Embase, and Cochrane Library databases were searched from inception to October 2021. The primary outcome was the clinical success rate. The secondary outcomes were acid exposure time, DeMeester score, need for proton pump inhibitors (PPIs), endoscopic findings, and adverse events.

Results

Fifteen studies were included. The pooled clinical success rate was 73.8% (95% confidence interval (CI) = 69%-78%) overall, 68.6% (95% CI = 62.2%-74.4%) with ARMS, 86.7% (95% CI = 78.7%-91.9%) with ARMA, and 76.5% (95% CI = 65%-85.1%) with ARBL. ARMI resulted in significantly improved acid exposure time, DeMeester score, and degree of hiatal hernia. Furthermore, 10% of patients had dysphagia requiring endoscopic dilatation after ARMS or ARMA, and ARMS was associated with a 2.2% perforation rate. By contrast, no bleeding, perforation, or severe dysphagia was noted with ARBL. Severe hiatal hernia (Hill grade III) may predict treatment failure with ARMA.

Conclusions

The three ARMI procedures were efficacious and safe for PPI-refractory GERD. ARMA and ARBL may be preferred over ARMS because of fewer adverse events and similar efficacy. Further studies are necessary to determine the optimal technique and patient selection.

Project description:ImportanceCohort studies, mainly based on questionnaires and interviews, have reported high rates of reflux recurrence after antireflux surgery, which may have contributed to a decline in its use. Reflux recurrence after laparoscopic antireflux surgery has not been assessed in a long-term population-based study of unselected patients.ObjectivesTo determine the risk of reflux recurrence after laparoscopic antireflux surgery and to identify risk factors for recurrence.Design and settingNationwide population-based retrospective cohort study in Sweden between January 1, 2005, and December 31, 2014, based on all Swedish health care and including 2655 patients who underwent laparoscopic antireflux surgery according to the Swedish Patient Registry. Their records were linked to the Swedish Causes of Death Registry and Prescribed Drug Registry.ExposuresPrimary laparoscopic antireflux surgery due to gastroesophageal reflux disease in adults (>18 years).Main outcomes and measuresThe outcome was recurrence of reflux, defined as use of antireflux medication (proton pump inhibitors or histamine2 receptor antagonists for >6 months) or secondary antireflux surgery. Multivariable Cox regression was used to assess risk factors for reflux recurrence.ResultsAmong all 2655 patients who underwent antireflux surgery (median age, 51.0 years; interquartile range, 40.0-61.0 years; 1354 men [51.0%]) and were followed up for a median of 5.6 years, 470 patients (17.7%) had reflux recurrence; 393 (83.6%) received long-term antireflux medication and 77 (16.4%) underwent secondary antireflux surgery. Risk factors for reflux recurrence included female sex (hazard ratio [HR], 1.57 [95% CI, 1.29-1.90]; 286 of 1301 women [22.0%] and 184 of 1354 men [13.6%] had recurrence of reflux), older age (HR, 1.41 [95% CI, 1.10-1.81] for age ≥61 years compared with ≤45 years; recurrence among 156 of 715 patients and 133 of 989 patients, respectively), and comorbidity (HR, 1.36 [95% CI, 1.13-1.65] for Charlson comorbidity index score ≥1 compared with 0; recurrence among 180 of 804 patients and 290 of 1851 patients, respectively). Hospital volume of antireflux surgery was not associated with risk of reflux recurrence (HR, 1.09 [95% CI, 0.77-1.53] for hospital volume ≤24 surgeries compared with ≥76 surgeries; recurrence among 38 of 266 patients [14.3%] and 271 of 1526 patients [17.8%], respectively).Conclusions and relevanceAmong patients who underwent primary laparoscopic antireflux surgery, 17.7% experienced recurrent gastroesophageal reflux requiring long-term medication use or secondary antireflux surgery. Risk factors for recurrence were older age, female sex, and comorbidity. Laparoscopic antireflux surgery was associated with a relatively high rate of recurrent gastroesophageal reflux disease requiring treatment, diminishing some of the benefits of the operation.

Project description:BackgroundGastroesophageal reflux disease (GERD), which leads to acid reflux into the esophagus, is a common gastrointestinal disorder. Several studies have shown the prevalence of GERD in Iranian population, but their evidence is contradictory. Therefore, the present study was conducted to investigate the epidemiology of GERD in Iran.MethodsThe entire steps of this systematic review and meta-analysis were based on the MOOSE protocol, and the results were reported accordance with the PRISMA guideline. This review is registered on PROSPERO (registration number: CRD42020142861). To find potentially relevant published articles, comprehensive search was done on international online databases Scopus, Science Direct, EMBASE, PubMed/Medline, CINAHL, EBSCO, Cochrane Library, Web of Science, Iranian online databases and the Google Scholar search engine in June 2019. Cochran test and I2 index were used to assess the heterogeneity of the studies. Data were analyzed using Comprehensive Meta-Analysis software ver. 2. The significance level of the test was considered to be P < 0.05.ResultsThe daily, weekly, monthly, and overall prevalence of GERD symptoms in Iranian population was 5.64% (95%CI [confidence interval]: 3.77-8.35%; N = 66,398), 12.50% (95%CI: 9.63-16.08%; N = 110,388), 18.62% (95%CI: 12.90-26.12%; N = 70,749) and 43.07% (95%CI: 35.00-51.53%; N = 73,189), respectively. The daily, weekly, monthly, and overall prevalence of heartburn in Iranian population was 2.46% (95%CI: 0.93-6.39%; N = 18,774), 9.52% (95%CI: 6.16-14.41%; N = 54,125), 8.19% (95%CI: 2.42-24.30%; N = 19,363) and 23.20% (95%CI: 13.56-36.79%; N = 26,543), respectively. The daily, weekly, monthly, and overall prevalence of regurgitation in Iranian population was 4.00% (95%CI: 1.88-8.32%; N = 18,774), 9.79% (95%CI: 5.99-15.60%; N = 41,140), 13.76% (95%CI: 6.18-44.31%; N = 19,363) and 36.53% (95%CI: 19.30-58.08%; N = 21,174), respectively. The sensitivity analysis for prevalence of all types GERD, heartburn and regurgitation symptoms by removing a study showed that the overall estimate is still robust.ConclusionThe present meta-analysis provides comprehensive and useful information on the epidemiology of GERD in Iran for policy-makers and health care providers. This study showed a high prevalence of GERD in Iran. Therefore, effective measures on GERD-related factors such as lifestyle can be among the health policies of Iran.

Project description:Background and objectivesIn this systematic review, we evaluated the efficacy, mechanisms and safety of three neuromodulation therapies in patients with gastroesophageal reflux disease (GERD), including the effect of neuromodulation therapies on symptoms and key GERD pathophysiologies, lower esophageal sphincter (LES) pressure, esophageal motility, gastric motility, and parasympathetic activity. The first therapy is LES electrical stimulation using an implantable electrical stimulator, the second is transcutaneous electrical acustimulation, and the third is manual acupuncture.MethodsA systematic review of literature according to the PRISMA guidelines was performed. Online databases searched include Medline (Ovid), Embase, and PubMed. Studies were assessed for inclusion and exclusion criteria with Covidence, a systematic review software.ResultsThe analysis included thirteen clinical studies. Four papers included were registered under two open-label trials on ClinicalTrials.gov for LES electrical stimulation; Five randomized trials with sham-treated controls were analyzed for transcutaneous electrical acustimulation; Four studies, including three involving standard therapy controls and one involving shamtreated controls were included for manual acupuncture. All evaluated studies demonstrated significant beneficial effects on GERD symptoms, using patient-completed questionnaires, objective 24-h measurement of esophageal pH, and patient-reported use of proton pump inhibitors. In evaluating the effect on key GERD pathophysiologies, electrical stimulation significantly increased LES pressure, and transcutaneous electrical acustimulation significantly improved esophageal motility, gastric motility, and parasympathetic activity. None of the evaluated neuromodulation methods produced severe adverse effects.ConclusionsCumulative evidence from the evaluated studies indicates that neuromodulation therapies were effective in treating the GERD symptoms and key underlying GERD pathophysiologies. They are thus valuable options for individualized GERD treatment.
