Abstract Background and study aims Antireflux mucosectomy (ARMS) and antireflux mucosal ablation (ARMA) are new endoscopic procedures for patients with gastroesophageal reflux disease (GERD). We conducted a meta-analysis to systematically assess the feasibility, clinical success, and safety of these procedures. Patients and methods We searched Embase, PubMed, and Cochrane Central from inception to October 2020. Overlapping reports, animal studies, and case reports were excluded. Our primary outcomes were clinical success and adverse events (AEs). Secondary outcomes included technical success, endoscopic esophagitis, 24-hour pH monitoring, and proton pump inhibitor (PPI) use. A random effects model was used to pool data. Results In total, 15 nonrandomized studies (12 ARMS, n = 331; 3 ARMA, n = 130) were included; 10 were conducted in patients with refractory GERD. The technical success rate was 100 %. The pooled short-term (first assessment within the first 6 months), 1-year, and 3-year clinical success rates were 78 % (95 % confidence interval [95 %CI] 70 %–85 %), 72% (95 %CI 47 %–92 %), and 73 % (95 %CI 65 %–81 %), respectively. ARMS and ARMA yielded similar clinical success. The proportion of patients off PPIs at 1 year was 64 % (95 %CI 52 %–75 %). There were significant drops (P < 0.01) in validated clinical questionnaires scores, presence of esophagitis, and acid exposure time. The most common AE (11 %, 95 %CI 8 %–15 %) was dysphagia requiring dilation (7%, 95 %CI 5 %–11 %). Four cases of perforation were recorded, all in patients undergoing ARMS. Conclusions Our meta-analysis of nonrandomized studies suggests that ARMS and ARMA are safe and effective for patients with GERD.

ABSTRACT BACKGROUND: Gastroesophageal reflux disease (GERD) is a clinical condition that develops when the reflux of stomach contents causes troublesome symptoms and/or complications. Transient lower esophageal sphincter relaxation is the main pathophysiological mechanism of GERD. Symptoms and complications can be related to the reflux of gastric contents into the esophagus, oral cavity, larynx and/or the lung. Symptoms and other possible manifestations of GERD are heartburn, regurgitation, dysphagia, non-cardiac chest pain, chronic cough, chronic laryngitis, asthma and dental erosions. The proton pump inhibitor (PPI) is the first-choice drug and the most commonly medication used for the treatment of GERD. The most widespread definition of Refractory GERD is the clinical condition that presents symptoms with partial or absent response to twice-daily PPI therapy. Persistence of symptoms occurs in 25% to 42% of patients who use PPI once-daily and in 10% to 20% who use PPI twice-daily. OBJECTIVE: The objective is to describe a review of the current literature, highlighting the causes, diagnostic aspects and therapeutic approach of the cases with suspected reflux symptoms and unresponsive to PPI. CONCLUSION: Initially, the management of PPI refractoriness consists in correcting low adherence to PPI therapy, adjusting the PPI dosage and emphasizing the recommendations on lifestyle modification change, avoiding food and activities that trigger symptoms. PPI decreases the number of episodes of acid reflux; however, the number of “non-acid” reflux increases and the patient continues to have reflux despite PPI. In this way, it is possible to greatly reduce greatly the occurrence of symptoms, especially those dependent on the acidity of the refluxed material. Response to PPI therapy can be evaluated through clinical, endoscopic, and reflux monitoring parameters. In the persistence of the symptoms and/or complications, other causes of Refractory GERD should be suspected. Then, diagnostic investigation must be initiated, which is supported by clinical parameters and complementary exams such as upper digestive endoscopy, esophageal manometry and ambulatory reflux monitoring (esophageal pH monitoring or esophageal impedance-pH monitoring). Causes of refractoriness to PPI therapy may be due to the true Refractory GERD, or even to other non-reflux diseases, which can generate symptoms similar to GERD. There are several causes contributing to PPI refractoriness, such as inappropriate use of the drug (lack of patient adherence to PPI therapy, inadequate dosage of PPI), residual acid reflux due to inadequate acid suppression, nocturnal acid escape, “non-acid” reflux, rapid metabolism of PPI, slow gastric emptying, and misdiagnosis of GERD. This is a common cause of failure of the clinical treatment and, in this case, the problem is not the treatment but the diagnosis. Causes of misdiagnosis of GERD are functional heartburn, achalasia, megaesophagus, eosinophilic esophagitis, other types of esophagitis, and other causes. The diagnosis and treatment are specific to each of these causes of refractoriness to clinical therapy with PPI.

BACKGROUND: Wireless pH studies can offer prolonged pH monitoring, which may potentially facilitate the diagnosis and management of patients with gastroesophageal reflux disease (GERD). The aim of the present study was to evaluate the detection rate of abnormal esophageal acid exposure using prolonged pH monitoring in patients with suspected or refractory GERD symptoms.METHODS: Patients undergoing prolonged ambulatory pH studies for the evaluation of GERD-related symptoms were assessed. Patients with a known diagnosis of GERD were tested on medical therapy, while patients with suspected GERD were tested off therapy. The wireless pH capsules were placed during upper endoscopy 6 cm above the squamocolumnar junction.RESULTS: One hundred ninety-one patients underwent a total of 198 pH studies. Fifty ambulatory pH studies (25%) were excluded from the analysis: 27 patients (14%) had insufficient data capture (less than 18 h on at least one day of monitoring), 15 patients had premature capsule release (7%), seven were repeat studies (3.5%) and one had intolerable pain requiring capsule removal (0.5%). There were 115 patients undergoing pH studies who were off medication, and 33 patients were on therapy. For the two groups of patients, results were as follows: 32 (28%) and 22 (67%) patients with normal studies on both days; 58 (50%) and five (15%) patients with abnormal studies on both days; 18 (16%) and three (9%) patients with abnormal studies on day 1 only; and seven (6%) and three (9%) patients with abnormal studies on day 2 only, respectively.CONCLUSIONS: Prolonged 48 h pH monitoring can detect more abnormal esophageal acid exposure but is associated with a significant rate of incomplete studies.

Abstract Background and study aims Proton pump inhibitors (PPI) are effective medical therapy options for gastro-esophageal reflux disease (GERD). However, 20 % to 40 % of patients report symptoms despite taking daily PPI. Transoral incisionless fundoplication (TIF2) and magnetic sphincter augmentation (MSA) are less invasive options for the treatment of refractory GERD and are increasingly gaining popularity. Methods We conducted a comprehensive search of several databases to identify relevant studies. Our primary aim was to compare the efficacy of both interventions reported as improvement in Gastroesophageal Reflux Disease-Health Related Quality of Life (GERD-HRQL) score, overall patient satisfaction, improvement in post-procedure regurgitation, and fraction of patients completely off PPI therapy at follow up. Results Twenty-four studies with 1942 patients were included in the final analysis. Both MSA and TIF2 had comparable technical success and clinical success based on improvement in GERD-HRQL scores i. e. 98.8 % (CI 95.6,99.7) vs 98.5 % (CI 95.7,99.5) and 80.4 % (CI 66,89.6) vs 77.7 % (CI 64.1,87.2), respectively. A significantly greater proportion of patients reported improvement in regurgitation, i. e. 91.1 % (CI 83.8,95.3) vs 73.1 % (CI 62.5,81.7) and were able to completely discontinue PPI therapy with MSA compared to TIF2 i. e. 91.3 % (CI 81.5,96.2) vs 63.8 % (CI 51.6,74.4). Patients’ BMI and presence of a hiatal hernia did not have any effect on procedural outcomes. Conclusion Both procedures performed at par when comparing clinical success in terms of improvement in GERD-HRQL scores. In terms of overall patient satisfaction, post procedure regurgitation and cumulative number of patients off PPI therapy, MSA outperforms TIF2.

Purpose of the review to present up-to-date data on the causes, methods of diagnosis and treatment of the refractory form of gastroesophageal reflux disease (GERD). Refractory GERD is the preservation of typical symptoms of the disease and/or incomplete healing of the esophageal mucosa against the background of taking a standard dose of proton pump inhibitors (PPI) once a day for 8 weeks. The reasons for the lack of response to the treatment are divided into related to the patient, related to therapy, and not related to GERD. Diagnostic approaches include x-ray examination of the esophagus and stomach, endoscopy with biopsy, 24-hour Impedance-pH monitoring, esophageal manometry. Depending on the reasons for the lack of response to the therapy, treatment may include lifestyle changes, doubling the dose of PPI, replacing PPI with another, adding H2-receptor antagonists, prokinetics, antacids, alginates and adsorbents. If conservative treatment is ineffective, it is possible to consider alternative methods, such as surgical treatment. Refractory GERD is a serious clinical problem. The absence of an answer to 8-week therapy with PPI requires a thorough differential diagnosis using additional examination methods. The identification of the causes of refractory to the therapy allows to optimize the approaches to its overcoming and to choose the optimal treatment.

Belching is a common phenomenon. However, it becomes bothersome if excessive. Impedance–pH monitoring can classify the belching into two types: gastric belching and supragastric belching (SGB). The former is a physiological mechanism to vent swallowed air from the stomach, whereas the latter is a behavioral disorder. Gastroesophageal reflux disease (GERD) is the most relevant condition in both types of belching. Recent findings have raised awareness that excessive SGB possibly sheds light on the pathogenesis of a part of proton pump inhibitor (PPI) refractoriness in GERD. SGB could cause typical reflux symptoms such as heartburn, regurgitation or chest pain in two ways: SGB-induced gastroesophageal reflux or SGB-induced esophageal distension. In PPI-refractory GERD, it is important to detect hidden SGB as a cause of reflux symptoms since SGB requires psychological treatment instead of high dose PPIs or pain modulators. In the case of PPI-refractory GERD with excessive SGB, recent studies imply that the combination of a psychological approach and conventional treatment can improve treatment outcome.

BACKGROUND: Gastric reflux is one of the most important causes of the referral of patients to the internal clinic, which in some cases causes problems for patients due to resistance to common treatments. Therefore, timely diagnosis and treatment of this group of patients are very important.AIM: The purpose of the present study was to determine the off-proton pump inhibitor (off-PPI) 24 h pH-impedance analyses in patients with refractory gastroesophageal reflux disease (GERD) attending to Taleghani Hospital since 2009 to 2017.METHODS: In this observational descriptive-comparative off-PPI study, 572 patients with refractory GERD who were referred to Taleghani Hospital in Tehran from 2009 to 2017 were selected, and the results of 24 h pH Impedance analysis were then assessed.RESULTS: The results of 24h pH-impedance indicated that 7% of cases belonged to Pure Acid Reflux followed by weakly Acid (1%), non-acid (0.3%), mixed & gas (5.2%), functional (58.4%) and oesophagal hypersensitivity (28%). Furthermore, weakly acid plus acid was also found to be 8% and Weakly Acid + Acid + Non-Acid were determined as 8.3%.CONCLUSIONS: Our findings suggested that nearly more than half of the patients with refractory GERD would have a functional disorder in the 24h pH-impedance analysis.

Abstract Background Given poor symptomatic response rates and rising awareness of the adverse events associated with the long-term use of proton pump inhibitors (PPIs), endoscopic modalities for treatment of refractory gastroesophageal reflux disease (GERD) have become more prominent. The aim of this study was to perform a systematic review and meta-analysis to evaluate feasibility, efficacy, and tolerability of transoral incisionless fundoplication (TIF) for the treatment of refractory GERD. Methods Searches of PubMed, EMBASE, Web of Science, and Cochrane Library databases were performed to March 2017. Measured outcomes included immediate technical success rate and serious adverse events. Symptomatic improvement was measured using GERD Health-related Quality of Life (HRQL), Gastroesophageal Reflux Symptom Score (GERSS), and Reflux Symptom Index (RSI). Objective success was determined by hiatal hernia reduction and pH monitoring. Results 32 studies (1475 patients; 48.2 % male) met inclusion criteria. TIF success rate was 99 % (95 % confidence interval [CI] 97 to 100; P < 0.001), with an adverse event rate of 2 % (95 %CI 1 to 3; P < 0.001). GERD HRQL, GERSS, and RSI improved significantly post-TIF (mean difference 17.72, 95 %CI 17.31 to 18.14; mean difference 23.78, 95 %CI 22.96 to 24.60; mean difference 14.28, 95 %CI 13.56 to 15.01; all P < 0.001, respectively). Hernia reduction occurred in 91 % of patients (95 %CI 83 to 98; P < 0.001). DeMeester scores improved significantly (mean difference 10.22, 95 %CI 8.38 to 12.12; P < 0.001). PPI therapy was discontinued post-procedure in 89 % of patients (95 %CI 82 to 95; P < 0.001). Conclusions TIF appears to be a safe and effective endoscopic procedure for patients with refractory GERD. Future controlled trials are needed to directly compare efficacy, long-term durability, and safety between TIF and Nissen fundoplication.

Idiopathic pulmonary fibrosis (IPF) and gastroesophageal reflux disease (GERD) are undoubtedly related. Even though it is not clear yet which one is the primary disease, they certainly interact increasing each other’s severity. Symptoms are unreliable to diagnose GERD in patients with IPF, and objective evaluation with pH monitoring and/or bronchoalveolar lavage analysis is mandatory. Pharmacological treatment with proton pump inhibitors (PPIs) may bring control of IPF in few patients, but PPIs do not control reflux but just change the pH of the gastric refluxate. Surgical therapy based on a fundoplication is safe and effective as it controls any type of reflux, independently from the pH of the gastric refluxate. In patients waiting for lung transplantation (if they can tolerate a laparoscopic operation under general anesthesia), a fundoplication before the operation might block the progression of IPF, while after transplantation it might prevent rejection by preventing the bronchiolitis obliterans syndrome.
