Abstract
PURPOSE In gastro-esophageal reflux disease (GERD) requiring surgical treatment, concomitant ineffective esophageal motility (IEM) is a decisive factor in surgical planning, due to concern regarding dysphagia. Anti-reflux surgery with the RefluxStop device is a promising technique. We assessed initial feasibility and clinical outcomes of RefluxStop surgery in patients with GERD and IEM. METHODS Retrospective analysis of patients with GERD, hiatal hernia (HH), and IEM, who underwent surgery with RefluxStop at our institution and achieved 12-month follow-up. Technique feasibility was assessed, in addition to symptom resolution (GERD-HRQL questionnaire), adverse events, HH recurrence, dysphagia, and patient satisfaction. Placement of the device was confirmed by video fluoroscopy on postoperative day 1, and at 3 and 12 months. RESULTS Between June 2020 and November 2022, 20 patients with IEM underwent surgery with RefluxStop and completed 12-month follow-up. All patients reported typical symptoms of GERD, and 12 had preoperative dysphagia. The median HH length was 4.5 cm (IQR, 3.75-5). The median operating time was 59.5 min (IQR, 50.25-64) with no implant-related intra- or postoperative complications. No HH recurrence was observed. One patient reported persistent left-sided thoracic pain at 11 months post-surgery, which required diagnostic laparoscopy and adhesiolysis. Three patients reported severe postoperative dysphagia: balloon dilatation was performed towards resolution. The mean GERD-HRQL scores improved (from 40.7 at baseline to 4.8 at 3 months and 5.7 at 12 months (p <0.001)). CONCLUSION RefluxStop surgery was feasible and offered effective treatment for this group of patients with GERD and IEM. All patients had complete resolution or significant improvement of GERD symptoms, and 90% of them were satisfied with their quality of life 1 year after surgery.

Abstract
Gastroesophageal reflux disease (GERD) is common, with increasing worldwide disease prevalence and high economic burden. A significant number of patients will remain symptomatic following an empiric proton pump inhibitor (PPI) trial. Persistent symptoms despite PPI therapy are often mislabeled as refractory GERD. For patients with no prior GERD evidence (unproven GERD), testing is performed off antisecretory therapy to identify objective evidence of pathologic reflux using criteria outlined by the Lyon consensus. In proven GERD, differentiation between refractory symptoms (persisting symptoms despite optimized antisecretory therapy) and refractory GERD (abnormal reflux metrics on ambulatory pH impedance monitoring and/or persistent erosive esophagitis on endoscopy while on optimized PPI therapy) can direct subsequent management. While refractory symptoms may arise from esophageal hypersensitivity or functional heartburn, proven refractory GERD requires personalization of the management approach, tapping from an array of non-pharmacologic, pharmacologic, endoscopic, and surgical interventions. Proper diagnosis and management of refractory GERD is critical to mitigate undesirable long-term complications such as strictures, Barrett's esophagus, and esophageal adenocarcinoma. This review outlines the diagnostic workup of patients presenting with refractory GERD symptoms, describes the distinction between unproven and proven GERD, and provides a comprehensive review of the current treatment strategies available for the management of refractory GERD.

Abstract
BACKGROUND The 3rd edition of the evidence-based clinical practice guidelines for gastroesophageal reflux disease (GERD) 2021 from the Japanese Society of Gastroenterology states that the treatment strategy for potassium-competitive acid blocker (PCAB)-refractory GERD remains unclear. Furthermore, even if GERD improves with the administration of an acid secretion inhibitor, it is feared that GERD may flare up after discontinuation of the drug, resulting in some cases in which patients are forced to take vonoprazan semipermanently (the so-called PCAB-dependent cases). From a global perspective, PCAB is not yet used in all countries and regions, and measures that can be taken now for cases in which a conventional proton pump inhibitor (PPI) is inadequately effective need to be devised. SUMMARY Endoscopic treatment for GERD may be effective in cases where conventional proton pump inhibitors are ineffective; however, there are insufficient long-term studies to corroborate this, and its cost effectiveness is unknown. Other treatment options for PCAB or PPI-refractory GERD include surgical procedures (Nissen and Toupet operations), which have a longer history than endoscopic treatment for GERD. However, their long-term results are not as good as those of acid secretion inhibitors, and they are not cost effective. Endoscopic treatment for GERD may fill gaps in inadequate surgical treatment. In April 2022, endoscopic anti-reflux mucosal resections (ARMS [anti-reflux mucosectomy] and ESD-G [endoscopic submucosal dissection for GERD]) were approved for reimbursement, making endoscopic treatment of GERD possible throughout Japan. KEY MESSAGES It is important to identify the background factors in cases in which endoscopic treatments are effective.

Abstract
BACKGROUND Anti-reflux mucosectomy (ARMS) is a choice for proton pump inhibitor (PPI)-dependent patients with gastroesophageal reflux disease (GERD). We present an extended anti-reflux mucosectomy, named ligation-assisted anti-reflux mucosectomy (L-ARMS). The aim of this study was to assess the feasibility of the procedure and short-term outcomes on PPI use and symptom resolution. METHODS Institutional review board approval was obtained for retrospective review of a prospectively collected database including patients who underwent L-ARMS. L-ARMS includes mucosa ligation and endoscopic mucosectomy without submucosal injection around the squamocolumnar junction. The GERD symptoms, endoscopy, 24-h pH monitoring results, and manometry were collected by chart review. Voluntary validated surveys assessed symptomatic improvement over time. RESULTS There were 69 patients available for review. The procedure was technically completed in all cases with no severe complications, and the average operation time was 33 min. At 6 months after L-ARMS, treatment with PPIs had been halted in 55.1% of the patients, 30.4% of the enrolled patients used PPIs occasionally, and the lower esophageal sphincter (LES) pressure, DeMeester scores, and GERD-health-related quality of life questionnaire (GERD-HRQL) scores showed a significant improvement compared with the baseline measurements (P < 0.001). Forty-five patients complained of mild dysphagia and were relieved in 4 weeks with no specific treatment. Compared to patients without dysphagia, patients complained of dysphagia after surgery had better clinical benefits indicated by GERD-HRQL and DeMeester score. CONCLUSIONS As a modified ARMS, L-ARMS is an effective procedure for controlling GERD symptoms, esophageal acid exposure, and LES pressure, which can be safely performed endoscopically in a time-saving and simple manner.

Abstract
Endoscopic therapies in proton pump inhibitors (PPI) dependent/refractory gastroesophageal reflux disease (GERD) are increasingly indicated in patients who are not suitable or willing for chronic medical therapy and surgical fundoplication. Currently available endoluminal anti-reflux procedures include radiofrequency therapy (Stretta), suturing/plication and mucosal ablation/resection techniques at the gastroesophageal junction. Meticulous work up and patient selection results in a favorable outcome with these endoscopic therapies, especially the quality of life and partially the PPI independence. Stretta can be considered in patients with PPI refractory GERD and might have a role in patients with reflux hypersensitivity and functional heartburn. Endoscopic fundoplication using the Esophyx device and the GERD-X device have strong evidence (multiple randomized controlled trials) in patients with small hiatus hernia and high volume reflux episodes. Mucosal resection/ablation techniques like anti-reflux mucosectomy and anti-reflux mucosal ablation have shown promising results but need long term follow-up studies to prove their efficacy. The subset of PPI dependent GERD population will benefit from endoscopic therapies and the future of endoscopic management of GERD looks promising.

Abstract
Gastroesophageal reflux disease (GERD) is a common disease that may cause a huge economic burden. Endoscopy is performed not only to rule out other organic diseases but also to diagnose reflux esophagitis or Barrett's esophagus. Non‐erosive GERD (non‐erosive reflux disease [NERD]) is called endoscopy‐negative GERD; however, GERD‐related findings could be obtained through histological assessment, image‐enhanced endoscopy, and new endoscopic modalities in patients with NERD. Moreover, endoscopy is useful to stratify the risk for the development of GERD. In addition, endoscopic treatments have been developed. These techniques could significantly improve patients’ quality of life as well as symptoms.

Abstract
Gastroesophageal reflux disease (GERD) is one of the most common gastrointestinal diseases encountered in primary care and gastroenterology clinics. Most cases of GERD can be diagnosed based on clinical presentation and risk factors; however, some patients present with atypical symptoms, which can make diagnosis difficult. An esophagogastroduodenoscopy can be used to assist in diagnosis of GERD, though only half of these patients have visible endoscopic findings on standard white light endoscopy. This led to the development of new advanced endoscopic techniques that enhanced the diagnosis of GERD and related complications like squamous cell dysplasia, Barrett's esophagus, and early esophageal adenocarcinoma. This is conducted by improved detection of subtle irregularities in the mucosa and vascular structures through optical biopsies in real-time. Management of GERD includes lifestyle modifications, pharmacological therapy, endoscopic and surgical intervention. Minimally invasive endoscopic intervention can be an option in selected patients with small hiatal hernia and without complications of GERD. These endoscopic interventions include endoscopic fundoplication, endoscopic mucosal resection techniques, ablative techniques, creating mechanical barriers, and suturing and stapling devices. As these new advanced endoscopic techniques are emerging, data surrounding the indications, advantages and disadvantages of these techniques need a thorough understanding.

Abstract
Sudden death in epilepsy or SUDEP is a fatal condition that accounts for more than 4000 deaths each year. Limited clinical and preclinical data on sudden death suggest critical contributions from autonomic, cardiac, and respiratory pathways. A potential mechanism for such sudden and severe cardiorespiratory dysregulation may be linked to acid reflux-induced laryngospasm. Here, we expand on our previous investigations and utilize a novel multimodal approach to provide visual evidence of acid reflux-initiated cardiorespiratory distress and subsequent sudden death in seizing rats. We used systemic kainic acid to acutely induce seizure activity in Long Evans rats, under urethane anesthesia. We recorded electroencephalography (EEG), electrocardiography (ECG), chest plethysmography, and esophageal pH signals through a multimodal recording platform, during simultaneous fast MRI scans of the rat stomach and esophagus. MRI images, in correlation with electrophysiology data were used to identify seizure progression, stomach acid movement up the esophagus, cardiorespiratory changes, and sudden death. In all cases of sudden death, esophageal pH recordings alongside MRI images visualized stomach acid movement up the esophagus. Severe cardiac (ST segment elevation), respiratory (intermittent apnea) and brain activity (EEG narrowing due to hypoxia) changes were observed only after acid reached larynx, which strongly suggested onset of laryngospasm following acid reflux. The complementary information coming from electrophysiology and fast MRI scans provided insight into the mechanism of esophageal reflux, laryngospasm, obstructive apnea, and subsequent sudden death in seizing animals. The results carry clinical significance as it outlines a potential mechanism that may be relevant to SUDEP in humans.

Abstract
Background/Aims Increased esophagogastric junction (EGJ) relaxation is the most important mechanism involved in gastroesophageal reflux disease (GERD). An endoscopic functional luminal imaging probe (EndoFLIPⓇ) is a device used to quantify EGJ distensibility in routine endoscopy. The aim of the current study was to assess the usefulness of EndoFLIPⓇ for the diagnosis of GERD compared to normal controls. Methods We analyzed EndoFLIPⓇ data from 204 patients with erosive reflux disease (ERD), 310 patients with nonerosive reflux disease (NERD), and 277 normal subjects. EndoFLIPⓇ uses impedance planimetry to measure 16 cross-sectional areas (CSAs) in conjunction with the corresponding intrabag pressure within a 4.6 cm cylindrical segment of a fluid-filled bag. The EGJ distensibility was assessed using 40 mL volume-controlled distensions. Results The mean distensibility index values were 13.98 mm2/mm Hg in ERD patients, 11.42 mm2/mm Hg in NERD patients, and 9.1 mm2/mm Hg in normal subjects. There were significant differences in EGJ distensibility among the three groups (p<0.001). In addition, the CSAs were significantly higher in the ERD (291.03±160.77 mm2) and NERD groups (285.87±155.47 mm2) than in the control group (249.78±144.76 mm2, p=0.004). We determined the distensibility index cutoff value of EGJ as 10.95 for the diagnosis of GERD by receiver operating characteristic curve analysis. Conclusions The EGJ distensibilities of GERD patients were higher than those of normal subjects, regardless of the presence of reflux esophagitis. Thus, the measurement of EGJ distensibility using the EndoFLIPⓇ system could be useful in the diagnosis of GERD.

Abstract
BACKGROUNDS AND AIMS New mucosal resective and ablative endoscopic procedures based on gastric cardiac remodeling to prevent reflux have appeared. We aimed to evaluate the feasibility of a new ablative technique named antireflux ablation therapy (ARAT) for control of GERD in patients without hiatal hernia. METHODS Patients with proton pump inhibitor (PPI)-refractory GERD without hiatal hernia underwent ARAT between January 2016 and October 2019. Gastroesophageal Reflux Disease-Health-Related Quality of Life (GERD-HRQL), upper endoscopy, 24-hour pH monitoring, and PPI use were documented at 3, 6, 12, 24, and 36 months after ARAT. RESULTS One hundred eight patients were included (61 men [56.5%]; median age, 36.5 years; range, 18-78 years). ARAT was performed on all patients. At the 36-month evaluation, 84 patients had completed the protocol. Median ARAT time was 35.5 minutes (range, 22-51 minutes), and median circumference ablation was 300° (range, 270°-320°). No major adverse events occurred, and 14 of 108 patients (12.9%) presented with stenosis that was responsive to balloon dilation (<5 sessions). At the 3-month evaluation, the acid exposure time (AET), DeMeester score, and GERD-HRQL score had decreased from 18.8% to 2.8% (P = .001), 42.5 to 9.1 (P = .001), and 36.5 to 10 (P = .02), respectively, and these values were maintained up to 36 months. Success (AET <4%) was achieved in 89% and 72.2% at 3 and 36 months, respectively. Related factors at 36 months were as follows: pre-ARAT Hill type II (odds ratio [OR], 3.212; 95% confidence interval [CI], 1.431-5.951; P = .033), post-ARAT 3-month Hill type I (OR, 4.101; 95% CI, 1.812-9.121; P = .042), and AET <4% at 3 months (OR, 5.512; 95% CI, 1.451-7.621; P = .021). CONCLUSIONS ARAT is a feasible, safe, and effective therapy for early and mid-term treatment of GERD in patients without a sliding hiatal hernia. However, longer follow-up evaluations and randomized comparative studies are needed to clarify its real role. (Clinical trial registration number: NCT03548298.).

Anti-reflux mucosectomy (ARMS) results in improved recovery and similar reflux quality of life outcomes compared to laparoscopic Nissen fundoplication. Surg Endosc 2020; 35:7174-7182. [PMID: 33237465 DOI: 10.1007/s00464-020-08144-9] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Accepted: 10/27/2020] [Indexed: 12/16/2022]
Abstract
BACKGROUND Anti-reflux mucosectomy (ARMS) is a new endoscopic procedure involving a hemi-circumferential endoscopic mucosal resection (EMR) around the gastroesophageal junction. We aim to compare perioperative and quality of life outcomes of patients with reflux who underwent ARMS to a comparable group who underwent laparoscopic Nissen fundoplication (NF). METHODS A retrospective review of a prospectively maintained quality database was performed. All patients who underwent ARMS (n = 33) were matched with patients who underwent NF (n = 67). Clinical and quality of life (QOL) outcomes were collected preoperatively and up to two years postoperatively, measured by the Reflux Symptom Index (RSI), Gastroesophageal Reflux Disease-Health Related Quality of Life (GERD-HRQL), and Dysphagia Score. Outcomes were compared using the Wilcoxon rank-sum and Fisher's exact test. RESULTS While 10 patients (30.3%) who underwent ARMS required additional laparoscopic anti-reflux operations, the ARMS group had shorter OR time (p<0.001), less estimated blood loss (p<0.001), shorter hospital stay (p<0.001), less pain at discharge (p = 0.007), earlier narcotic discontinuation (p<0.001), and earlier return to activities of daily living (p<0.001) compared to the NF group. There was no difference in 30-day complication rates, emergency room visits, or readmission rates between the groups. There was no difference between ARMS and NF groups in terms of GERD-HRQL, RSI, or Dysphagia scores at 3 weeks, 6 months, 1 year, or 2 years postoperatively. However, the ARMS group reported less symptoms of gas and bloating postoperatively at all time points (all p<0.05). Both groups reported increased dysphagia at 3 weeks postoperatively (p<0.01) but this did not persist at 6 months, 1 year, or 2 years. CONCLUSION While ARMS had better perioperative outcomes compared to NF, reflux quality of life outcomes were comparable. ARMS can be an effective endoscopic intervention for GERD when performed on appropriately selected patients without limiting future laparoscopic anti-reflux interventions.

Abstract
Gastroesophageal reflux disease (GERD) is a common clinical condition for which our understanding has evolved over the past decades. It is now considered a cluster of phenotypes with numerous anatomical and physiological abnormalities contributing to its pathophysiology. As such, it is important to first understand the underlying mechanism of the disease process for each patient before embarking on therapeutic interventions. The aim of our paper is to highlight the mechanisms contributing to GERD and review investigations and interpretation of these results. Finally, the paper reviews the available treatment modalities for this condition, ranging from medical intervention, endoscopic options through to surgery and its various techniques.

Abstract
PURPOSE OF REVIEW This paper aims to review the definition and diagnostic criteria for reflux hypersensitivity and comment on the present and future management of this condition. RECENT FINDINGS In 2016, the Rome IV criteria redefined reflux hypersensitivity as characterized by typical reflux symptoms, absence of endoscopic mucosal disease, absence of pathologic gastroesophageal reflux, and positive symptom correlation between reflux and heartburn episodes. Though uncertain, TPRV1 receptors have been implicated in the pathophysiology of reflux hypersensitivity. Recent studies have shown neuromodulators like SSRIs, SNRIs, and TCAs may be the future of managing this condition. With the release of the Rome IV criteria and availability of continuous pH monitoring, the diagnosis of reflux hypersensitivity has become more streamlined. Though there is no definitive therapy for reflux hypersensitivity, several anti-secretory agents and neuromodulators have shown some efficacy in therapeutic trials. The lack of large-scale, randomized controlled trials, however, reinforces the need for further research into the pharmacotherapy of reflux hypersensitivity.

Abstract
BACKGROUND AND AIMS Currently available endoscopic or minimally invasive antireflux modalities are not widely accepted due to high procedure cost or inconsistent results. Therefore, a simpler and less technically demanding method is required. We evaluated the feasibility and efficacy of new endoscopic antireflux method (the Ripple Procedure) using functional lumen imaging probe (FLIP). METHODS This 5-week survival study included 10 domestic pigs (control, n = 4; experimental [Ripple], n = 6). The procedure includes the following steps: (i) semicircular marking along the lesser curvature of the cardia; (ii) submucosal injection; and (iii) semicircular mucosal incision along the marking. Endoscopic and FLIP evaluations were performed preoperatively and on postoperative days (PODs) 14 and 35. Technical feasibility was evaluated, and FLIP parameters, including the distensibility index (DI) at the esophagogastric junction (EGJ) and histopathological findings, were compared between groups. RESULTS The median procedure time was 28 (23.5-33.8) min. There was no significant difference in dysphagia score and body weight between groups. On POD 35, the Ripple group showed significantly lower EGJ DI at 30 mL [2.0 (1.3-2.5) vs 4.9 (2.7-5.0), P = 0.037]. The EGJ DI was significantly reduced at 30 mL, compared with that at the baseline level [- 59.0% (- 68.8% to - 32.1%) vs 27.8% (- 26.3% to 83.1%), P = 0.033]. Histologic evaluation revealed submucosal granulation tissues near the mucosal incision site, with increased intervening fibrosis between lower esophageal sphincter fibers in the Ripple group. CONCLUSION The EGJ DI significantly decreased after the Ripple Procedure; hence, the procedure appears to be feasible and effective in this porcine model.

Per-oral endoscopic myotomy and gastroesophageal reflux: Where do we stand after a decade of "POETRY"? Indian J Gastroenterol 2019; 38:287-294.

Abstract
Per-oral endoscopic myotomy (POEM) was introduced nearly a decade ago. Since then, the literature on its safety and efficacy has been ever increasing. Initial studies focused solely on the feasibility and efficacy of this procedure in patients with idiopathic achalasia. Subsequent studies analyzed the incidence of gastroesophageal reflux disease (GERD) in addition to the efficacy of POEM. These studies depict a high incidence of GERD after POEM. However, vast majority of these studies lacked a comprehensive evaluation of GERD after POEM. Consequently, it is difficult to provide a true estimate of the incidence of GERD in these patients. Majority of the patients with post-POEM GERD are asymptomatic and those with symptoms usually respond well to proton pump inhibitors. However, the long-term consequences of asymptomatic GERD with increased esophageal acid exposure are not well known. These patients should probably undergo regular surveillance due to theoretical risks of complications like Barrett's esophagus and esophageal adenocarcinoma. It should be acknowledged that there is no well-controlled study to support the strategy of surveillance in this group of patients. Given the high incidence of GERD after POEM, it is time to devise minimally invasive novel strategies to prevent and manage post-POEM GERD. The current literature suggests that the technique of POEM and other factors like type of achalasia do not influence the occurrence of GERD after POEM. Therefore, the endoscopists will need to think out of the box to prevent post-POEM GERD.

Abstract
Gastroesophageal reflux disease (GERD) is one of the most commonly encountered gastrointestinal diseases in outpatient clinics. Proton pump inhibitors (PPIs) are the cornerstone of the treatment of GERD. However, approximately one-third of patients have suboptimal response to PPIs. The management options in such cases include antireflux surgery or endoscopic antireflux treatments. Antireflux surgery is not popular due to its invasive nature and potential for adverse events. Therefore, minimally invasive endoscopic antireflux therapies are gaining popularity for the management of PPI-dependent and PPI-refractory GERD. These endoscopic therapies include radiofrequency application, endoscopic fundoplication modalities, and mucosal resection techniques. In appropriately selected patients, the response to these endoscopic modalities is encouraging. Unlike surgical fundoplication, endoscopic antireflux therapies are less likely to be associated with complications such as dysphagia and gas-bloat syndrome. On the other hand, antireflux surgery remains the ideal treatment in patients with a large hiatal hernia (laparoscopic Nissen fundoplication), morbid obesity (gastric bypass), and severe reflux esophagitis. Endoscopic treatment modalities bear the potential to narrow the treatment gap between PPIs and antireflux surgery. Long-term follow-up studies and randomized comparison with antireflux surgery are required to provide a clear understanding of the current role of endoscopic modalities in patients with PPI-refractory and PPI-dependent GERD.

Abstract
Gastroesophageal reflux disease (GERD) is one of the most common gastrointestinal diseases. Several studies have been carried out on the treatment of symptoms associated with GERD. The present study aimed to compare the effect of Psyllium seed and oral omeprazole on GERD in patients with functional constipation. In this trial, 132 patients were divided into 2 groups. The impact of omeprazole and Psyllium seed on the treatment and recurrence of GERD was studied. Among the patients, the rate of response to treatment was 89.2% (n = 58) in the Psyllium seed group, while in omeprazole group, it was 94% (n = 63; P = .31). The recurrence rates of Psyllium seed and omeprazole groups were 24.1% (n =14) and 69.8% (n = 44), respectively (P < .001). The results showed that treatment of functional constipation by Psyllium seed in patients with GERD leads to improvement of GERD and its recurrences in comparison with omeprazole.

Abstract
A significant percentage of patients with gastroesophageal reflux disease (GERD) will not respond to proton pump inhibitor (PPI) therapy. The causes of PPI-refractory GERD are numerous and diverse, and include adherence, persistent acid, functional disorders, nonacid reflux, and PPI bioavailability. The evaluation should start with a symptom assessment and may progress to imaging, endoscopy, and monitoring of esophageal pH, impedance, and bilirubin. There are a variety of pharmacologic and procedural interventions that should be selected based on the underlying mechanism of PPI failure. Pharmacologic treatments can include antacids, prokinetics, alginates, bile acid binders, reflux inhibitors, and antidepressants. Procedural options include laparoscopic fundoplication and LINX as well as endoscopic procedures, such as transoral incisionless fundoplication and Stretta. Several alternative and complementary treatments of possible benefit also exist.
