Abstract
Background/Aims Ineffective esophageal motility is the most frequent disorder of esophageal peristalsis. Symptoms may include dysphagia, chest pain, and heartburn. Our aims are to evaluate the long-term prognosis and determine if provocative tests during high-resolution esophageal manometry could predict the prognosis. Methods We retrospectively assessed high resolution manometries performed between 2015-2018 in adult patients. Symptoms were evaluated at baseline and at follow-up (median 39 months later) using the impact dysphagia questionnaire (IDQ-10), where a score ≥ 7 defined dysphagia, the gastroesophageal reflux disease questionnaire (GerdQ), where a score ≥ 9 defined symptoms of reflux disease and if the subject had chest pain ≥ once a week. Chicago classifications version 3.0 and 4.0 were used. The contractile reserve was assessed by identifying whether esophageal peristalsis normalized or not on solid bolus swallows and a rapid drink challenge was included. Results Nine hundred and eighty investigations performed during the study period; 114 patients (11.6%) were identified with ineffective esophageal motility. The final study cohort consisted of 33 patients of which 42% had dysphagia at follow-up and 25% had chest pain at least once a week, 46% had reflux symptoms. Patients who normalized motility on solid bolus swallows reported less dysphagia upon follow-up (P = 0.012), nevertheless reported similar proportions of chest pain (P = 0.632), and reflux (P = 0.514). There were no associations between having dysphagia, chest pain, or reflux at follow-up, and abnormal findings on the rapid drink challenge (P > 0.05 for all). Conclusions Patients with ineffective esophageal motility continue to experience long-term esophageal symptoms at follow-up. Provocative tests seem to have the potential to partly predict the long-term prognosis of dysphagia.

An indication-based analysis of the yield and findings of esophageal high-resolution manometry. Scand J Gastroenterol 2025; 60:368-374. [PMID: 40052859 DOI: 10.1080/00365521.2025.2475083] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2024] [Revised: 02/23/2025] [Accepted: 02/28/2025] [Indexed: 04/02/2025]
Abstract
BACKGROUND High-resolution manometry (HRM) is the gold standard for the diagnosis of esophageal motility disorders. While studies have previously reported on HRM findings in patients with dysphagia and/or chest pain, we sought to compare the yield and findings of HRM based on different indications for motility testing. METHODS A retrospective study was performed including all successful HRM studies performed at two tertiary medical centers between 2018 and 2023. The indication was categorized as either: (1) dysphagia; (2) GERD evaluation; (3) non-cardiac chest pain; (4) epigastric pain; (5) regurgitation/vomiting; or (6) prior to esophageal surgery. Motility disorders were diagnosed as per the Chicago Classification, version 4.0. RESULTS A total of 768 patients were included (mean age 55.5 +/- 17.3; 56.2% female). The most common indications were dysphagia (368, 47.9%) and prior to reflux testing (267, 34.8%). Normal motility was found in 417 (54.3%) patients while a motility disorder was diagnosed in 351 (45.7%) subjects. A major motility disorder was found in 178 (23.2%) cases, with achalasia in 82 (10.7%) patients. HRM diagnoses significantly differed based on the indication for testing (p < 0.001), with major motility disorders and achalasia being most commonly diagnosed when performed for dysphagia and recurrent regurgitation/vomiting. The indication affected the likelihood of having any motility disorder (p = 0.010), a major motility disorder (p < 0.001), a disorder of EGJ Outflow (p < 0.001), and achalasia (p < 0.001). CONCLUSIONS The indication for HRM testing affects the likelihood of having a motility disorder including achalasia. The highest yield is in patients being evaluated for dysphagia and regurgitation/vomiting.

Abstract
Esophageal motility disorders (EMDs) encompass a range of functional abnormalities, including achalasia, ineffective esophageal motility (IEM), esophagogastric junction outflow obstruction (EGJOO), and distal esophageal spasm (DES). Diagnostic modalities like high-resolution esophageal manometry (HREM), Functional Lumen Imaging Probe (FLIP), and impedance analysis are invaluable but often limited by interpretive variability and the need for expert analysis. Artificial intelligence (AI) has emerged as a transformative tool in addressing these challenges. This manuscript explores the integration of AI in EMD diagnostics, showcasing its ability to enhance diagnostic accuracy, optimize workflows, and standardize interpretation across centers. Advanced algorithms, including convolutional neural networks (CNNs) and machine learning (ML) models, achieve high accuracy in automating classifications, subtyping disorders like achalasia, and improving diagnostic consistency. Furthermore, AI's predictive capabilities extend to treatment outcome modeling, enabling personalized care strategies and longitudinal tracking. AI also offers significant potential in medical education by reducing learning curves and standardizing esophageal motility interpretation training. These advancements collectively emphasize the role of AI in revolutionizing EMD diagnosis, treatment, and training, promising improved patient outcomes and broader clinical utility.

Abstract
Among the various factors implicated in the pathogenesis of gastroesophageal reflux disease (GERD), visceral hypersensitivity and mucosal resistance have been recently re-evaluated in relation to the increasing phenomenon of proton pump inhibitor failure, particularly in patients with nonerosive reflux disease (NERD). Intensive research has allowed us to understand that noxious substances contained in the refluxate are able to interact with esophageal epithelium and to induce the elicitation of symptoms. The frequent evidence of microscopic esophagitis able to increase the permeability of the mucosa, the proximity of sensory afferent nerve fibers to the esophageal lumen favoring the higher sensitivity to noxious substances and the possible activation of inflammatory pathways interacting with sensory nerve endings are pathophysiological alterations confirming that mucosal resistance is impaired in GERD patients. Accordingly, the reinforcement of protective mechanisms of esophageal mucosa by topical therapies has become a novel treatment target. Alginate, the combination of hyaluronic acid+chondroitin sulphate and Poliprotect have been shown to adhere to esophageal mucosa and to have good protective properties. Several placebo-controlled clinical trials have shown that these compounds, given alone or as add-on therapy for short periods, enable to relieve symptoms and to improve the quality of life in NERD patients. Further studies are needed to confirm the above results and to find new mucosal protectants in order to improve the management of NERD patients.

Abstract
Esophageal motility disorders can have a major impact on quality of life. Dysphagia is the most commonly reported symptom; however, patients with esophageal dysmotility can also present with other symptoms such as chest pain and tightness, food impaction, regurgitation and heartburn. It is important to be aware of the spectrum of esophageal motility disorders so that timely and accurate diagnosis can be made. The Chicago Classification uses a hierarchical classification system that divides motility disorders as disorders of outflow obstruction and disorders of peristalsis. The disorders of esophago-gastric junction (EGJ) outflow include Type I, II and III achalasia and EGJ outflow obstruction. The disorders of peristalsis include absent contractility, distal esophageal spasm, hypercontractile esophagus, and ineffective esophageal motility. There are several diagnostic tools such as endoscopy, barium esophagram, high resolution manometry, and functional luminal imaging probe that can aid in evaluating esophageal motility disorders. A multidisciplinary approach including a primary care physician, radiologist, gastroenterologist, and surgeon may be beneficial for accurate diagnosis and proper treatment. The purpose of this paper is to discuss the diagnosis and management of esophageal dysmotility disorders other than achalasia.

Abstract
BACKGROUND This study aimed to investigate the clinical characteristics and esophageal motility of patients with gastric cardia submucosal tumors (SMTs) and the associated changes after endoscopic resection based on high-resolution impedance manometry (HRIM). METHODS From our electronic database, we identified patients who underwent pre-operative evaluation of gastric cardia SMTs between 2015 and 2023. All patients completed standardized symptom questionnaires and underwent endoscopic ultrasonography and HRIM. Endoscopic resection via submucosal dissection or submucosal tunnel endoscopic resection was performed, followed by esophagogastroduodenoscopy and HRIM three months later. Esophageal motility on HRIM was compared based on the updated Chicago Classification v4.0. RESULTS Thirty patients (mean age, 47.4 ± 12.8 years; male, 50%) were analyzed. Most patients were asymptomatic (43.3%), while others presented with epigastralgia, regurgitation, chest pain, or dysphagia. On endoscopic ultrasonography, the average tumor size was 16.7 ± 4.5 mm (range, 10.0-30.0 mm), and most tumors originated from the fourth layer (80%). On HRIM, eight patients (26.7%) had abnormal esophageal motility, including five with ineffective esophageal motility (IEM) and three with esophagogastric junction outflow obstruction. Complete resection was achieved in 25 of the 27 patients (92.6%) who underwent endoscopic treatment. Pathology revealed leiomyomas (96%) and gastrointestinal stromal tumors (4%). No significant differences in symptom profiles or HRIM parameters were observed after tumor resection. Three patients with pre-operative IEM exhibited normal motility at the follow-up HRIM. CONCLUSION Up to 26.7% of patients with gastric cardia SMTs had abnormal esophageal motility on HRIM. Endoscopic resection of these SMTs was effective and safe and appeared to improve esophageal motility in patients with IEM.

Abstract
Esophageal symptoms, including dysphagia, heartburn, and non-cardiac chest pain, are prevalent concerns in gastroenterology. This review examines the roles of advanced diagnostic modalities such as high-resolution manometry (HRM), pH-impedance monitoring, and EndoFLIP in understanding esophageal physiology and pathology. Here, we discuss the clinical presentations of common esophageal symptoms and explore how structural abnormalities like strictures and motility disorders, including achalasia and esophageal spasms, are assessed using these tools. The diagnostic utility of endoscopy in visualizing mucosal and structural changes is highlighted alongside emerging technologies like artificial intelligence in enhancing detection capabilities. Complementary techniques, such as barium esophagrams and reflux monitoring, provide additional functional and anatomical insights, crucial for comprehensive patient evaluation. The integration of these diagnostic approaches fosters a deeper understanding of esophageal disorders, guiding effective management strategies and improving patient outcomes. This review aimed to highlight the importance of adopting a multimodal diagnostic approach in modern gastroenterological practice.

Abstract
Background/Aims Multiple rapid swallows (MRS) is a provocative test during high-resolution esophageal manometry (HRM) to evaluate contraction reserve (CR). This study aims to determine the prevalence of CR in patients with ineffective esophageal motility (IEM) and MRS performed in the upright position, and to assess the ideal number of MRS sequences. Methods We enrolled adult patients diagnosed with IEM according to the Chicago classification version 4.0 who underwent HRM with 3 MRS sequences. Presence of CR was identified as either: the distal contraction integral (DCI) of the post-MRS sequence exceeding the mean DCI of single swallows (ratio > 1) or the mean DCI of the 3 post-MRS sequences surpassing the mean DCI of single swallows. The occurrence of CR was compared following 1, 2, and 3 MRS sequences. Results When assessing CR in 57 patients referenced to mean single supine swallow DCI, the pooled prevalence of CR following 1, 2, and 3 MRS sequences was 23/57 (40.4%), 31/57 (54.4%), and 33/57 (57.9%), respectively. More patients had CR after 2 MRS sequences compared to 1 (P < 0.001), but there was no significant difference in CR between 2 and 3 MRS sequences (P = 0.160). More patients had CR after 2 (P = 0.013) and 3 MRS sequences (P = 0.034) when CR was referenced to single upright compared to single supine swallows. Conclusion Among patients with IEM, 58.0% had CR after 3 upright MRS sequences and 2 were adequate to assess CR.

Diagnosis of Retrograde Cricopharyngeus Dysfunction Using High Resolution Impedance Manometry and Comparison With Control Subjects. Clin Gastroenterol Hepatol 2025:S1542-3565(25)00070-9.

Abstract
BACKGROUND & AIMS Retrograde cricopharyngeal dysfunction (R-CPD) or inability to belch has been linked to ineffective relaxation of the upper esophageal sphincter (UES) during gastroesophageal gas reflux, and botulinum toxin (BT) injection into the UES has demonstrated success in case series. However, the diagnosis is often overlooked. High resolution impedance manometry (HRiM) with belch provocation was recently suggested as diagnostic tool. Our aim was to confirm manometric findings in patients with R-CPD before and after BT treatment and to compare with control patients and healthy volunteers. METHODS Retrospective analysis of HRiM with belch provocation was performed between May 2021 and April 2024. Gas reflux episodes were counted and analyzed for UES relaxation, air clearance, air entrapment, or oscillatory movements of air in the esophagus, among others. RESULTS Fifty-five patients with symptoms suggestive of R-CPD, 30 control patients, and 15 healthy volunteers were included (n = 100). Twenty-nine patients had a repeat measurement after treatment with BT (n = 29). Median esophageal contractility was lower in R-CPD versus control patients and healthy volunteers (distal contractile integral: 146, 577, and 316 mmHg.cm.s, Padj = .0109). During belching, we saw higher UES pressures in R-CPD patients vs controls, leading to incomplete air clearance and air oscillating in the esophagus (P < .0001). After BT injection, median UES pressures during belching decreased (56 vs 3 mmHg), and air clearance improved (P < .0001). A maximum UES pressure during belching >31 mmHg adequately discriminated patients from controls. CONCLUSIONS Rapid drinking challenge with sparkling water can serve as belch provocation test during HRiM, with higher UES pressures during gas reflux and oscillations discriminating R-CPD patients from controls.

Abstract
BACKGROUND Understanding the relationship between distal contractile integral (DCI) and mean nocturnal baseline impedance (MNBI) could shed light on new diagnostic and treatment strategies, specifically concerning nocturnal reflux. This study aimed to assess this relationship to enhance our comprehension of the interplay between esophageal contractility and mucosal permeability. METHODS We identified adult patients who had high resolution esophageal manometry and pH-impedance tests performed within a 30-day period between December 2018 and March 2022. A random forest model was used to identify significant predictors of MNBI, assisting with variable selection for a following regression analysis. Subsequently, both univariable and multivariable regression models were utilized to measure the association between predictors and MNBI. KEY RESULTS Our study included 188 patients, primarily referred for testing due to reflux. The most common motility diagnoses were normal (62%) followed by possible esophagogastric junction outflow obstruction (22%). The mean DCI was 2020 mmHg∙s∙cm and MNBI was 3.05 kΩ. The random forest model identified 12 significant predictors for MNBI, key variables being acid exposure time (AET), total proximal reflux events, intraabdominal lower esophageal sphincter length, hiatal hernia presence, and DCI. Subsequent multivariable regression analyses demonstrated log AET (β = -0.69, p = <0.001), total proximal reflux events (β = -0.16, p = 0.008), hiatal hernia presence (β = -0.82, p = 0.014), log DCI (β = 1.26, p < 0.001), and age (β = -0.13, p = 0.036) as being significantly associated with MNBI. CONCLUSIONS AND INFERENCES DCI is a key manometric predictor of MNBI emphasizing the role of manometry in detecting reflux risk and the need for its consideration in reflux management.

Effect of hiatal hernia and esophagogastric junction morphology on esophageal motility: Evidence from high-resolution manometry studies. Neurogastroenterol Motil 2024; 36:e14929. [PMID: 39344398 DOI: 10.1111/nmo.14929] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2024] [Revised: 09/01/2024] [Accepted: 09/15/2024] [Indexed: 10/01/2024]
Abstract
BACKGROUND High-resolution Manometry (HRM) is the most sensitive and specific test available for clinical assessment of hiatal hernia (HH), a common condition defined as the separation between the Lower Esophageal Sphincter (LES) and crural diaphragm (CD). While the link between HH and Gastroesophageal Reflux Disease (GERD) is established, the potential association of HH with esophageal dysmotility, independently from GERD, is uncertain. This study aimed to analyze if HH, with or without GERD, can associate with esophageal motility disorders. METHODS Consecutive patients without previous esophageal surgery who underwent HRM between 2018 and 2022 were enrolled. All patients with symptoms suggestive of GERD underwent impedance-pH testing off-therapy. HH was defined as a separation >1 cm between LES and CD, and esophagogastric junction (EGJ) morphology was classified as: Type I, when there was no separation between LES and CD; Type II, in case of minimal separation (>1 and <3 cm); Type III, when ≥3 cm of separation was present. Demographic and clinical characteristics were collected at baseline, including Age, Gender, Alcohol-, Coffee- and Smoke-habits, GERD diagnosis and symptoms' duration. Two cohorts of patients, with and without HH, were retrospectively individuated, and their association with Ineffective Peristalsis, Hypercontractile Esophagus and Outflow Obstruction was analyzed with univariate and multivariate Logistic regressions using the statistical software R. KEY RESULTS 848 consecutive patients were enrolled, and 295 cases of HH (34.8%), subdivided into 199 (23.5%) Type II- and 96 (11.3%) Type III-EGJ patients, were identified. Ineffective peristalsis was diagnosed in 162 (19.1%) subjects, Hypercontractile esophagus in 32 (3.8%), and Outflow Obstruction in 91 (10.7%), while GERD was present in 375 (44.2%) patients. HH was significantly associated with Ineffective Peristalsis (p < 0.001) and GERD (p < 0.001). Furthermore, HH resulted to be a risk factor for Ineffective peristalsis (OR 2.0, 95% CI 1.4-2.8, p < 0.001) both when the analysis was conducted in all the 848 subjects, independently from GERD, and when it was carried out in patients without GERD (OR 2.3, 95% CI 1.02-5.3, p = 0.04). The risk for Ineffective Peristalsis increased 1.3 times for every centimeter of HH. No statistically significant association was found between HH and Outflow obstruction or Hypercontractile Esophagus. CONCLUSIONS & INFERENCES An increasing separation between the LES and CD may lead to a gradual and significant elevation in the risk of Ineffective Peristalsis. Interestingly, this association with HH is true in patients with and in those without GERD, suggesting that the anatomical alteration seems to play a major role in motility change.

Abstract
INTRODUCTION Gastroesophageal reflux disease (GERD) is a common debilitating chronic disease presenting in two main forms based on esophageal mucosal appearance, the erosive reflux disease (ERD) and the non-erosive reflux disease (NERD). Acid secretion is a key factor in the disease pathogenesis and management. Potent acid-suppressant drugs have been manufactured since the mid of 1970s, initially with histamine-H2-receptors antagonists, and later, inhibitors of the proton pump (H+-K+-ATPase).More recently, potassium-competitive acid blockers (p-CABs), particularlyVonoprazan, have been introduced. Vonoprazan has shown high efficacy and safety profiles and exhibits several advantages that allow to overcome shortcomings of proton pump inhibitors (PPIs). AREAS COVERED In this review, we provide an updated summary of Vonoprazan pharmacodynamics and its role in clinical practice for the management of erosive esophagitis and GERD-related heartburn. Moreover, we discuss characteristics of Vonoprazan that allow to bypass some limitations of the older PPIs. EXPERT OPINION Long-term safety and efficacy of Vonoprazan have already been demonstrated for the induction and maintenance of ERD, preventing nocturnal acid breakthrough, reducing reflux symptoms in non-responder to standard therapy. Ongoing and future studies are expected to further elucidate its long-term benefits and potential applications in other acid-related disorders.

[PMID: 39398395 PMCID: PMC11466451 DOI: 10.1159/000536583] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Accepted: 01/30/2024] [Indexed: 07/05/2024] Open
Abstract
BACKGROUND 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). SUMMARY 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. KEY MESSAGES 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
BACKGROUND AND PURPOSE Ineffective esophageal motility (IEM) is the most frequently diagnosed esophageal motility abnormality and characterized by diminished esophageal peristaltic vigor and frequent weak, absent, and/or fragmented peristalsis on high-resolution esophageal manometry. Despite its commonplace occurrence, this condition can often provoke uncertainty for both patients and clinicians. Although the diagnostic criteria used to define this condition has generally become more stringent over time, it is unclear whether the updated criteria result in a more precise clinical diagnosis. While IEM is often implicated with symptoms of dysphagia and gastroesophageal reflux disease, the strength of these associations remains unclear. In this review, we share a practical approach to IEM highlighting its definition and evolution over time, commonly associated clinical symptoms, and important management and treatment considerations. We also share the significance of this condition in patients undergoing evaluation for anti-reflux surgery and consideration for lung transplantation.

J Neurogastroenterol Motil 2024; 30:332-342.

Abstract
Background/Aims Ineffective esophageal motility (IEM) is common in patients with gastroesophageal reflux disease (GERD) and can be associated with poor esophageal contraction reserve on multiple rapid swallows. Alterations in the esophageal microbiome have been reported in GERD, but the relationship to presence or absence of contraction reserve in IEM patients has not been evaluated. We aim to investigate whether contraction reserve influences esophageal microbiome alterations in patients with GERD and IEM. Methods We prospectively enrolled GERD patients with normal endoscopy and evaluated esophageal motility and contraction reserve with multiple rapid swallows during high-resolution manometry. The esophageal mucosa was biopsied for DNA extraction and 16S ribosomal RNA gene V3-V4 (Illumina)/full-length (Pacbio) amplicon sequencing analysis. Results Among the 56 recruited patients, 20 had normal motility (NM), 19 had IEM with contraction reserve (IEM-R), and 17 had IEM without contraction reserve (IEM-NR). Esophageal microbiome analysis showed a significant decrease in microbial richness in patients with IEM-NR when compared to NM. The beta diversity revealed different microbiome profiles between patients with NM or IEM-R and IEM-NR (P = 0.037). Several esophageal bacterial taxa were characteristic in patients with IEM-NR, including reduced Prevotella spp. and Veillonella dispar, and enriched Fusobacterium nucleatum. In a microbiome-based random forest model for predicting IEM-NR, an area under the receiver operating characteristic curve of 0.81 was yielded. Conclusions In symptomatic GERD patients with normal endoscopic findings, the esophageal microbiome differs based on contraction reserve among IEM. Absent contraction reserve appears to alter the physiology and microbiota of the esophagus.

Abstract
Gastroesophageal reflux disease (GERD), a prevalent clinical condition, is often attributed to aberrant esophageal motility, leading to gastric content reflux and associated symptoms or complications. The rising incidence of GERD presents an escalating healthcare challenge. Endoscopic and esophageal reflux monitoring can provide a basis for the diagnosis of patients with gastroesophageal reflux disease, but when the diagnostic basis is at an inconclusive value, some additional supportive evidence will be needed. Advanced technology is the key to improving patient diagnosis, accurate assessment, and the development of effective treatment strategies. High-resolution esophageal manometry (HREM) and endoscopic functional lumen imaging probe (EndoFLIP) represent the forefront of esophageal motility assessment. HREM, an evolution of traditional esophageal manometry, is considered the benchmark for identifying esophageal motility disorders. Its widespread application in esophageal dynamics research highlights its diagnostic significance. Concurrently, EndoFLIP's emerging clinical relevance is evident in diagnosing and guiding the treatment of coexisting esophageal motility issues. This review integrates contemporary research to delineate the contributions of HREM, EndoFLIP, and novel technologies in GERD. It examines their efficacy in facilitating an accurate diagnosis, differentiating similar gastrointestinal disorders, quantifying the extent of reflux, assessing the severity of the disease, forecasting patient responsiveness to proton pump inhibitor therapy, and guiding decisions for surgical interventions. The overarching aim is to deepen the understanding of GERD's underlying mechanisms and advance the formulation of holistic, efficacious treatment approaches.

Abstract
Gastroesophageal reflux disease (GERD) presents a general health problem with a variety of symptoms and an impairment of life quality. Conservative therapies do not offer sufficient symptom relief in up to 30% of patients. Patients who suffer from ineffective esophageal motility (IEM) and also GERD may exhibit symptoms ranging from mild to severe. In cases where surgical intervention becomes necessary for this diverse group of patients, it is important to consider the potential occurrence of postoperative dysphagia. RefluxStop is a new alternative anti-reflux surgery potentially reducing postoperative dysphagia rates. In this bicentric tertiary hospital observational study consecutive patients diagnosed with PPI refractory GERD and IEM that received RefluxStop implantation were included. A first safety and efficacy evaluation including clinical examination and GERD-HRQL questionnaire was conducted. 40 patients (25 male and 15 female) were included. 31 patients (77.5%) were on PPI at time of surgery, with mean acid exposure time of 8.14% ± 2.53. The median hospital stay was 3 days. Postoperative QoL improved significantly measured by GERD HRQL total score from 32.83 ± 5.08 to 6.6 ± 3.71 (p < 0.001). A 84% reduction of PPI usage (p < 0.001) was noted. 36 patients (90%) showed gone or improved symptoms and were satisfied at first follow-up. Two severe adverse events need mentioning: one postoperative slipping of the RefluxStop with need of immediate revisional operation on the first postoperative day (Clavien-Dindo Score 3b) and one device migration with no necessary further intervention. RefluxStop device implantation is safe and efficient in the short term follow up in patients with GERD and IEM. Further studies and longer follow-up are necessary to prove long-lasting positive effects.

Dysphagia 2024; 39:369-375. [PMID: 37728794 PMCID: PMC11127881 DOI: 10.1007/s00455-023-10617-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2023] [Accepted: 08/11/2023] [Indexed: 09/21/2023]
Abstract
Menthol is thought to trigger gastroesophageal reflux disease (GERD) symptoms by influencing esophageal peristalsis and lower esophageal sphincter (LES) function. We evaluated the effect of esophageal menthol infusion on esophageal motility and the LES in healthy volunteers and in patients with GERD. High resolution manometry (HRM) catheter with attached thin tube for menthol infusion was placed transnasally. Protocol which included baseline recording, 16 water swallows (5 ml, 10 ml, and 15 ml) and the multiple rapid swallows was performed before and after esophageal infusion of menthol (3 mM, 20 min, 8 ml/min). We evaluated the effect of this infusion on the HRM parameters of esophageal peristalsis (distal contractile integral, distal latency, contractile front velocity) and the lower esophageal sphincter (LES) barrier function (integrated relaxation pressure and the inspiratory augmentation of the LES). Simultaneously we evaluated the quality and intensity of the symptoms during the menthol infusion. Esophageal infusion of menthol did not appreciably affect HRM measurements characterizing esophageal peristalsis and LES pressure in healthy subjects (N = 13) or GERD patients (N = 11). The magnitude of the distal contractile integral (5 ml) was changed neither in the healthy volunteers' group, (735 ± 127 vs. 814 ± 117 mmHg, p = 0.5), nor in the GERD patients (295 ± 78 vs. 338 ± 96 mmHg, p = 0.99). In healthy volunteers menthol did not change the inspiratory augmentation of the LES (8.67 ± 1.09 vs. 7.69 ± 0.96 mmHg, p = 0.15) and neither did for GERD patients (8.8 ± 1.18 vs. 8.22 ± 0.91 mmHg, p = 0.43). We observed no significant difference in any HRM parameter following menthol infusion, except for distal latency in 10 ml swallows. By contrast, menthol infusion induced significantly more intense discomfort in GERD patient than in healthy volunteers. Our results suggest no significant temporal effect of menthol on the esophageal motility or LES function, neither in healthy volunteers, nor in GERD. Arguably, other mechanisms are responsible for menthol-related heartburn.

Abstract
OBJECTIVE A definitive diagnosis of gastroesophageal reflux disease (GERD) depends on endoscopic and/or pH-study criteria. However, high resolution manometry (HRM) can identify factors predicting GERD, such as ineffective esophageal motility (IEM), esophago-gastric junction contractile integral (EGJ-CI), evaluating esophagogastric junction (EGJ) type and straight leg raise (SLR) maneuver response. We aimed to build and externally validate a manometric score (Milan Score) to stratify the risk and severity of the disease in patients undergoing HRM for suspected GERD. METHODS A population of 295 consecutive patients undergoing HRM and pH-study for persistent typical or atypical GERD symptoms was prospectively enrolled to build a model and a nomogram that provides a risk score for AET > 6%. Collected HRM data included IEM, EGJ-CI, EGJ type and SLR. A supplemental cohort of patients undergoing HRM and pH-study was also prospectively enrolled in 13 high-volume esophageal function laboratories across the world in order to validate the model. Discrimination and calibration were used to assess model's accuracy. Gastroesophageal reflux disease was defined as acid exposure time >6%. RESULTS Out of the analyzed variables, SLR response and EGJ subtype 3 had the highest impact on the score (odd ratio 18.20 and 3.87, respectively). The external validation cohort consisted of 233 patients. In the validation model, the corrected Harrel c-index was 0.90. The model-fitting optimism adjusted calibration slope was 0.93 and the integrated calibration index was 0.07, indicating good calibration. CONCLUSIONS A novel HRM score for GERD diagnosis has been created and validated. The MS might be a useful screening tool to stratify the risk and the severity of GERD, allowing a more comprehensive pathophysiologic assessment of the anti-reflux barrier.

Abstract
There is little information on the degree of concordance between the results obtained using the Chicago 3.0 (CCv3.0) and Chicago 4.0 (CCv4.0) protocols to interpret high-resolution manometry (HRM) seeking to determine the value provided by the new swallowing maneuvers included in the last protocol. This is a study of diagnostic tests, evaluating concordance by consistency between the results obtained by the CCv3.0 and CCv4.0 protocols, in patients undergoing HRM. Concordance was assessed with the kappa test. Bland-Altman scatter plots, and Lin's correlation-concordance coefficient (CCC) were used to assess the agreement between IRP measured with swallows in the supine and seated position or with solid swallows. One hundred thirty-two patients were included (65% women, age 53 ± 17 years). The most frequent HRM indication was dysphagia (46.1%). Type I was the most common type of gastroesophageal junction. The most frequent CCv4.0 diagnoses were normal esophageal motility (68.9%), achalasia (15.5%), and ineffective esophageal motility (IEM; 5.3%). The agreement between the results was substantial (Kappa 0.77 ± 0.05), with a total agreement of 87.9%. Diagnostic reclassification occurred in 12.1%, from IEM in CCv3.0 to normal esophageal motility in CCv4.0. Similarly, there was a high level of agreement between the IRP measured in the supine compared to the seated position (CCC0.92) and with solid swallows (CCC0.96). In conclusion, the CCv4.0 protocol presents a high concordance compared to CCv3.0. In the majority of manometric diagnoses there is no reclassification of patients with provocation tests. However, the more restrictive criteria of CCv4.0 achieve a better reclassification of patients with IEM.

Abstract
BACKGROUND High-resolution manometry (HRM) is performed for evaluation of esophageal symptoms, but patient outcome is unclear when no actionable motor disorder is identified. We evaluated long-term symptomatic outcome of patients with nonactionable HRM findings. METHODS Patients who underwent (HRM) studies in 2006-2008 were tracked. Patients with achalasia spectrum disorders, foregut surgery before or after HRM, and incomplete symptom documentation were excluded. Symptom questionnaires assessing dominant symptom intensity (DSI, product of symptom severity and frequency recorded on 5-point Likert scales) and global symptom severity (GSS, from 10 cm visual analog scale) were repeated. Change in symptom burden was compared against HRM motor findings using Chicago Classification 4.0 (CCv4.0), applied retroactively to 2006-2008 data. KEY RESULTS Overall, 134 patients (median age 68 years, 64.5% female) could be contacted. The majority (73.1%) had normal motility; others had ineffective esophageal motility (8.2%), esophagogastric junction outflow obstruction (13.4%), hypercontractile esophagus (3.0%), or absent contractility (2.2%), none managed invasively. Over 15 years of follow-up, DSI decreased from 8.0 (4.0-16.0) to 1.0 (0.0-6.0) (p < 0.001) and GSS improved from 5.5 (3.3-7.7) to 2.0 (0.0-4.0) (p < 0.001); improvement was consistent across CCv4.0 diagnoses and subgroups. The majority (82.8%) reported improvement over time, and antisecretory medication was the most effective intervention (83.0% improvement). There was no difference in medication efficacy (p = 0.75) or improvement in symptoms (p = 0.20) based on CCv4 diagnosis. CONCLUSIONS AND INFERENCES Esophageal symptoms improve with conservative symptomatic management over long-term follow-up when no conclusive obstructive motor disorders or achalasia spectrum disorders are found on HRM.

Abstract
Gastrointestinal symptoms in Parkinson's disease (PD) are among the most prevalent and debilitating of complications and present unique diagnostic and management challenges. Patients with PD commonly experience dysphagia, nausea, bloating, and constipation related to pathologic involvement of the enteric nervous system. In turn, gastrointestinal complications may impact motor fluctuations and the efficacy of levodopa therapy. This review will explore the common gastrointestinal manifestations of PD with an emphasis on clinical presentation, workup, and treatment strategies.

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
Background Dysphagia is a prevalent condition which may severely impact the patient's quality of life. However, there are still lacking standardized therapeutic options for esophageal motility disorders. Summary Dysphagia is defined as a subjective sensation of difficulty swallowing which can result from oropharyngeal or esophageal etiologies. Regarding esophageal dysphagia, after excluding structural causes and esophageal mucosal lesions, high-resolution manometry (HRM) is the gold standard for the diagnosis of esophageal motility disorders. HRM has not only improved the sensitivity for detecting achalasia but has also expanded our understanding of spastic and hypomotility disorders of the esophageal body. The Chicago Classification v4.0 uses a hierarchical approach and provides a standardized diagnosis of esophageal motility disorders, allowing a tailored therapeutic approach. Dysphagia is often a long-term health problem that broadly impacts health and well-being and leads to physical and psychosocial disability, namely, malnutrition and aspiration pneumonia, as well as social isolation, depression, and anxiety. Apart from achalasia, most esophageal motility disorders tend to have a benign long-term course with symptoms of dysphagia and noncardiac chest pain that can improve significantly over time. Patient-reported outcomes (PROs) are self-assessment tools that capture the patients' illness experience and help providers better understand symptoms from the patients' perspective. Therefore, PROs have a critical role in providing patient-centered care. Key Messages Motility disorders should be ruled out in the presence of nonobstructive esophageal dysphagia, and treatment options should be considered according to the severity of symptoms reported by the patient.

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) is a relatively new but increasingly therapeutic option for achalasia. In recent years, POEM has been used for nonachalasia esophageal motility disorders (NAEMDs), such as diffuse esophageal spasm, esophagogastric junction outlet obstruction, and hypercontractile disorder, with some clinical success. No studies thus far compare the outcomes of these two groups. We perform the first head-to-head comparison of outcomes after POEM in patients with achalasia and NAEMD. PATIENTS AND METHODS A retrospective analysis of all patients undergoing POEM at one university hospital by a single expert endoscopist from July 2021 to December 2022 was performed. All patients were symptomatic, and the presence of esophageal motility disorders was confirmed using multiple diagnostic modalities. These patients were then divided into 2 groups, achalasia and NAEMD, based on the underlying diagnosis. Statistical analysis of different clinical outcomes, including effectiveness and safety, was performed. RESULTS Thirty-seven patients (mean age: 59.55, females: 22) underwent POEM in the study period. Twenty patients had achalasia and 17 patients had NAEMD. The median myotomy length was 5.5 cm for the achalasia group and 10 cm for the NAEMD group. This excluded patients with esophagogastric junction outlet obstruction in which the median myotomy length was 3 cm. The procedure time, the duration of hospital stays, the rates of same-day discharge, and complications were similar between the two. Short-term outcomes of POEM for the two groups were similar with improvement in 94% of patients in the achalasia group and 93.75% in the NAEMD group. CONCLUSION Contrary to prior observations, our study highlights that POEM is equally effective in achieving clinical improvement in patients with NAEMD as achalasia over 6 months of follow-up. In addition, POEM has a comparable safety profile in both patient groups making it a feasible therapeutic option for these debilitating and challenging disorders.

Abstract
BACKGROUND In high resolution manometry (HRM), distal contractile integral post multiple rapid swallow augmentation is considered as contraction reserve. The relationship between contraction reserve and esophageal acid reflux remains unclear. The aim of this study was to explore the correlation between contraction reserve and esophageal acid exposure in ineffective esophageal motility (IEM) and normal HRM. METHODS Patients who underwent HRM and ambulatory reflux monitoring were retrospectively screened. Those with diagnosis of normal HRM or IEM were included in the analysis. The proportion of patients with abnormal acid exposure time (AET) was compared between patients with and without contraction reserve. Multivariate regression analysis was performed to determine the predictors of abnormal AET and contraction reserve. RESULTS A total of 338 patients, including 264 normal HRM and 74 IEM, were included in the analysis. In patients with normal HRM, proportion of abnormal total AET (AET > 6.0%) was significantly lower in patients with supine contraction reserve than patients without contraction reserve (13.85% vs. 24.63%, p = 0.027). Multivariate regression analysis showed that supine contraction reserve could independently predict abnormal total AET (OR = 0.468, 95% CI: 0.249-0.948, p = 0.034), while upright contraction reserve trended strongly (OR = 0.558, 95% CI: 0.290-1.071, p = 0.079). Subgroup analysis showed that upright contraction reserve was an independent predictor of abnormal total AET in patients with 50-70% infective swallows (OR = 0.205, 95% CI: 0.051-0.821, p = 0.025), whereas supine contraction reserve did not have predictive value (p = 0.359). CONCLUSIONS Supine contraction reserve correlates with esophageal acid reflux in patients with normal HRM, while only upright contraction reserve correlates with esophageal acid reflux in patients with infective swallows of 50-70%.

Abstract
Esophageal peristalsis involves a sequential process of initial inhibition (relaxation) and excitation (contraction), both occurring from the cranial to caudal direction. The bolus induces luminal distension during initial inhibition (receptive relaxation) that facilitates smooth propulsion by contraction travelling behind the bolus. Luminal distension during peristalsis in normal subjects exhibits unique characteristics that are influenced by bolus volume, bolus viscosity, and posture, suggesting a potential interaction between distension and contraction. Examining distension-contraction plots in dysphagia patients with normal bolus clearance, ie, high-amplitude esophageal peristaltic contractions, esophagogastric junction outflow obstruction, and functional dysphagia, reveal 2 important findings. Firstly, patients with type 3 achalasia and nonobstructive dysphagia show luminal occlusion distal to the bolus during peristalsis. Secondly, patients with high-amplitude esophageal peristaltic contractions, esophagogastric junction outflow obstruction, and functional dysphagia exhibit a narrow esophageal lumen through which the bolus travels during peristalsis. These findings indicate a relative dynamic obstruction to bolus flow and reduced distensibility of the esophageal wall in patients with several primary esophageal motility disorders. We speculate that the dysphagia sensation experienced by many patients may result from a normal or supernormal contraction wave pushing the bolus against resistance. Integrating representations of distension and contraction, along with objective assessments of flow timing and distensibility, complements the current classification of esophageal motility disorders that are based on the contraction characteristics only. A deeper understanding of the distensibility of the bolus-containing esophageal segment during peristalsis holds promise for the development of innovative medical and surgical therapies to effectively address dysphagia in a substantial number of patients.

Abstract
BACKGROUND In patients with paraesophageal hernias (PEH), the course of the esophagus is often altered, which may affect esophageal motility. High-resolution manometry (HRM) is frequently used to evaluate esophageal motor function prior to PEH repair. This study was performed to characterize esophageal motility disorders in patients with PEH as compared to sliding hiatal hernia and to determine how these findings affect operative decision-making. METHODS Patients referred for HRM to a single institution from 2015 to 2019 were included in a prospectively maintained database. HRM studies were analyzed for the appearance of any esophageal motility disorder using the Chicago classification. PEH patients had confirmation of their diagnosis at the time of surgery, and the type of fundoplication performed was recorded. They were case-matched based on sex, age, and BMI to patients with sliding hiatal hernia who were referred for HRM in the same period. RESULTS There were 306 patients diagnosed with a PEH who underwent repair. When compared to case-matched sliding hiatal hernia patients, PEH patients had higher rates of ineffective esophageal motility (IEM) (p<.001) and lower rates of absent peristalsis (p=.048). Of those with ineffective motility (n=70), 41 (59%) had a partial or no fundoplication performed during PEH repair. CONCLUSION PEH patients had higher rates of IEM compared to controls, possibly due to a chronically distorted esophageal lumen. Offering the appropriate operation hinges on understanding the involved anatomy and esophageal function of each individual. HRM is important to obtain preoperatively for optimizing patient and procedure selection in PEH repair.

Abstract
We define mixed esophageal disease (MED) as a disorder of esophageal structure and/or function that produces variable signs or symptoms, simulating-fully or in part other well-defined esophageal conditions, such as gastroesophageal reflux disease, esophageal motility disorders, or even neoplasia. The central premise of the MED concept is that of an overlap syndrome that incorporates selected clinical, endoscopic, imaging, and functional features that alter the patient's quality of life and affect natural history, prognosis, and management. In this article, we highlight MED scenarios frequently encountered in medico-surgical practices worldwide, posing new diagnostic and therapeutic challenges. These, in turn, emphasize the need for better understanding and management, aiming towards improved outcomes and prognosis. Since MED has variable and sometimes time-evolving clinical phenotypes, it deserves proper recognition, definition, and collaborative, multidisciplinary approach, be it pharmacologic, endoscopic, or surgical, to optimize therapeutic outcomes, while minimizing iatrogenic complications. In this regard, it is best to define MED early in the process, preferably by teams of clinicians with expertise in managing esophageal diseases. MED is complex enough that is increasingly becoming the subject of virtual, multi-disciplinary, multi-institutional meetings.

Abstract
BACKGROUND Lung transplantation (LTx) remains controversial in patients with absent peristalsis (AP) given the increased risk for gastroesophageal reflux (GER), and chronic lung allograft dysfunction. Furthermore, specific treatments to facilitate LTx in those with AP have not been widely described. Transcutaneous Electrical Stimulation (TES) has been reported to improve foregut contractility in LTx patients and therefore we hypothesize that TES may augment the esophageal motility of patients with ineffective esophageal motility (IEM). METHODS We included 49 patients, 14 with IEM, 5 with AP, and 30 with normal motility. All subjects underwent standard high-resolution manometry and intraluminal impedance (HRIM) with additional swallows as TES was delivered. RESULTS TES induced a universal impedance change observable in real-time by a characteristic spike activity. TES significantly augmented the contractile vigor of the esophagus measured by the distal contractile integral (DCI) in patients with IEM [median DCI (IQR) 0 (238) mmHg-cm-s off TES vs. 333 (858) mmHg-cm-s on TES; p = .01] and normal peristalsis [median DCI (IQR) 1545 (1840) mmHg-cm-s off TES vs. 2109 (2082) mmHg-cm-s on TES; p = .01]. Interestingly, TES induced measurable contractile activity (DCI > 100 mmHg-cm-s) in three out of five patients with AP [median DCI (IQR) 0 (0) mmHg-cm-s off TES vs. 0 (182) mmHg-cm-s on TES; p < .001]. CONCLUSION TES acutely augmented contractile vigor in patients with normal and weak/ AP. The use of TES may positively impact LTx candidacy, and outcomes for patients with IEM/AP. Nevertheless, further studies are needed to determine the long-term effects of TES in this patient population.

Abstract
BACKGROUND Esophageal motility disorders (EMDs) are caused by the impaired relaxation of the upper/lower esophageal sphincter and/or defective esophageal peristaltic contractions, resulting in dysphagia and noncardiac chest pain. High-resolution manometry (HRM) is essential for the diagnosis of primary EMD; however, the recognition of EMD and HRM by general practitioners in Japan is limited. This review summarizes the diagnosis of and treatment strategies for EMD. SUMMARY HRM is a specific test for the diagnosis of EMD, whereas endoscopy and barium swallow as screening tests provide characteristic findings (i.e., esophageal rosette and bird's beak sign) in some cases. It is important to note that manometric diagnoses apart from achalasia are often clinically irrelevant; therefore, the recently updated guidelines suggest additional manometric maneuvers, such as the rapid drink challenge, and further testing, including functional lumen imaging, for a more accurate diagnosis before invasive treatment. Endoscopic/surgical myotomy, pneumatic dilation, and botulinum toxin injections need to be considered for patients with achalasia and clinically relevant esophagogastric junction outflow obstruction. KEY MESSAGE Since the detailed pathophysiology of EMD remains unclear, their diagnosis needs to be cautiously established prior to the initiation of invasive treatment.

Abstract
OBJECTIVE To evaluate and characterize outcomes of MSA in patients with IEM. SUMMARY BACKGROUND DATA MSA improves patients with gastroesophageal reflux and normal motility. However, many patients have IEM, which could impact the outcomes of MSA and discourage use. METHODS An international, multi-institutional case control study of IEM patients undergoing MSA matched to normal patients was performed. Primary outcomes were new onset dysphagia and need for postoperative interventions. RESULTS A total of 105 IEM patients underwent MSA with matching controls. At 1 year after MSA: GERD-Health Related Quality of Life was similar; DeMeester scores in IEM patients improved to 15.7 and 8.5 in controls ( P = 0.021); and normalization of the DeMeester score for IEM = 61.7% and controls = 73.1% ( P = 0.079).In IEM patients, 10/12 (83%) with preop dysphagia had resolution; 11/66 (17%) had new onset dysphagia and 55/66 (83%) never had dysphagia. Comparatively, in non-IEM patients, 22/24 (92%) had dysphagia resolve; 2/24 (8%) had persistent dysphagia; 7/69 (10%) had new onset dysphagia, and 62/69 (90%) never had dysphagia.Overall, 19 (18%) IEM patients were dilated after MSA, whereas 12 (11%) non-IEM patients underwent dilation ( P = 0.151). Nine (9%) patients in both groups had their device explanted. CONCLUSIONS Patients with IEM undergoing MSA demonstrate improved quality of life and reduction in acid exposure. Key differences in IEM patients include lower rates of objective GERD resolution, lower resolution of existing dysphagia, higher rates of new onset dysphagia and need for dilation. GERD patients with IEM should be counselled about these possibilities.

Abstract
Background The effects of Helicobacter pylori (HP) eradication on gastroesophageal reflux disease (GERD) are yet to be fully elucidated. Few studies have investigated the mechanisms underlying the correlations between HP and GERD with prospective methods. The objective of this prospective clinical study was to explore the effects of HP eradication on GERD. Methods Patients diagnosed with both GERD and HP were included. High-resolution esophageal manometry (HRM), 24-h esophageal pH monitoring, and the Gastroesophageal Reflux Disease Questionnaire (GerdQ) were performed before and after the successful eradication of HP, and the data were compared using statistical analysis. Results Sixty-eight patients diagnosed with both GERD and HP were included. The After HP eradication group showed significantly decreased median distal contractile integral (DCI) [610.40 (847.45) vs. 444.90 (559.60)] and significantly increased median inefficient esophageal motility (IEM) [36.00 (50.00) vs. 60.00 (57.00)] in the HRM compared with those of the Before HP eradication group, indicating that HP eradication reduced esophageal peristalsis. The 24-h esophageal pH monitoring showed that the longest reflux event, the percentage of time that the pH was <4, the number of reflux episodes, and the DeMeester score were all significantly different between the Before and After HP eradication groups (P < 0.05), suggesting that HP eradication increased esophageal acid exposure. The After HP eradication group also had a significantly higher GerdQ score than that of the Before HP eradication group (P < 0.05). Conclusions HP eradication reduced esophageal peristalsis, enhanced esophageal acid exposure, and aggravated GERD symptoms, suggesting that HP infection may be a protective factor for GERD.

Abstract
Background The Chicago Classification version 4.0 (CCv4.0) of ineffective esophageal motility (IEM) is more stringent than the Chicago Classification version 3.0 (CCv3.0) definition. We aimed to compare the clinical and manometric features of patients meeting CCv4.0 IEM criteria (group 1) versus patients meeting CCv3.0 IEM but not CCv4.0 criteria (group 2). Methods We collected retrospective clinical, manometric, endoscopic, and radiographic data on 174 adults diagnosed with IEM from 2011 to 2019. Complete bolus clearance was defined as evidence of exit of the bolus by impedance measurement at all distal recording sites. Barium studies included barium swallow, modified barium swallow, and barium upper gastrointestinal series studies, and collected data from these reports include abnormal motility and delay in the passage of liquid barium or barium tablet. These data along with other clinical and manometric data were analyzed using comparison and correlation tests. All records were reviewed for repeated studies and the stability of the manometric diagnoses. Results Most demographic and clinical variables were not different between the groups. A lower mean lower esophageal sphincter pressure was correlated with greater percent of ineffective swallows in group 1 (n = 128) (r = -0.2495, P = 0.0050) and not in group 2. In group 1, increased percent of failed contractions on manometry was associated with increased incomplete bolus clearance (r = 0.3689, P = 0.0001). No such association was observed in group 2. A lower median integrated relaxation pressure was correlated with greater percent of ineffective contractions in group 1 (r = -0.1825, P = 0.0407) and not group 2. Symptom of dysphagia was more prevalent (51.6% versus 69.6%, P = 0.0347) in group 2. Dysphagia was not associated with intrabolus pressure, bolus clearance, barium delay, or weak or failed contractions in either group. In the small number of subjects with repeated studies, a CCv4.0 diagnosis appeared more stable over time. Conclusions CCv4.0 IEM was associated with worse esophageal function indicated by reduced bolus clearance. Most other features studied did not differ. Symptom presentation cannot predict if patients are likely to have IEM by CCv4.0. Dysphagia was not associated with worse motility, suggesting it may not be primarily dependent on bolus transit.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) is one of the most common diseases in North America and globally. The aim of this guideline is to provide evidence-based recommendations regarding the most utilized and available endoscopic and surgical treatments for GERD. METHODS Systematic literature reviews were conducted for 4 key questions regarding the surgical and endoscopic treatments for GERD in adults: preoperative evaluation, endoscopic vs surgical or medical treatment, complete vs partial fundoplication, and treatment for obesity (body mass index [BMI] ≥ 35 kg/m2) and concomitant GERD. Evidence-based recommendations were formulated using the GRADE methodology by subject experts. Recommendations for future research were also proposed. RESULTS The consensus provided 13 recommendations. Through the development of these evidence-based recommendations, an algorithm was proposed for aid in the treatment of GERD. Patients with typical symptoms should undergo upper endoscopy, manometry, and pH-testing; additional testing may be required for patients with atypical or extra-esophageal symptoms. Patients with normal or abnormal findings on manometry should consider undergoing partial fundoplication. Magnetic sphincter augmentation or fundoplication are appropriate surgical procedures for adults with GERD. For patients who wish to avoid surgery, the Stretta procedure and transoral incisionless fundoplication (TIF 2.0) were found to have better outcomes than proton pump inhibitors alone. Patients with concomitant obesity were recommended to undergo either gastric bypass or fundoplication, although patients with severe comorbid disease or BMI > 50 should undergo Roux-en-Y gastric bypass for the additional benefits that follow weight loss. CONCLUSION Using the recommendations an algorithm was developed by this panel, so that physicians may better counsel their patients with GERD. There are certain patient factors that have been excluded from included studies/trials, and so these recommendations should not replace surgeon-patient decision making. Engaging in the identified research areas may improve future care for GERD patients.

Clinical Characteristics of Patients With Ineffective Esophageal Motility by Chicago Classification Version 4.0 Compared to Chicago Classification Version 3.0. J Neurogastroenterol Motil 2023; 29:38-48. [PMID: 36606435 PMCID: PMC9837536 DOI: 10.5056/jnm21250] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/24/2021] [Revised: 09/16/2022] [Accepted: 09/16/2022] [Indexed: 01/07/2023] Open
Abstract
Background/Aims Chicago classification version 4.0 (CCv4.0) of esophageal motility disorders developed a more stringent diagnostic criteria for ineffective esophageal motility (IEM) than version 3.0. We studied the implications of the new diagnostic criteria on the prevalence of IEM, and clinically characterized and compared the population of patients who no longer meet diagnostic criteria for IEM to those who retain the diagnosis. Methods We included all consecutively performed high-resolution esophageal impedance manometries from 2014 to 2021. Three cohorts of patients with IEM were created: Patients with IEM by Chicago classification version 3.0 (CCv3.0; CC3 group), by CCv4.0 only (CC4 group), and by CCv3.0 who are now considered normal (Normal group). Demographics, manometric and reflux parameters, and clinical outcomes were compared. Results A total of 594 manometries were analyzed. Of those, 66 (11.1%) met criteria for IEM by CCv3.0 (CC3), 41 (62.0%) retained an IEM diagnosis using CCv4.0 criteria (CC4), while 25 (38.0%) patients no longer met criteria for IEM (Normal). The CC4 group had higher esophageal acid exposure, especially supine (% time - 18.9% vs 2.2%; P = 0.005), less adequate peristaltic reserve (22.0% vs 88.0%; P = 0.003), and higher Demeester score (49.0 vs 21.2; P = 0.017) compared to the Normal group. There was no difference in bolus clearance between the groups. Conclusions IEM under CCv4.0 has a stronger association with pathologic reflux, especially supine reflux, and inadequate peristaltic reserve, but impairment in bolus clearance is unchanged when compared with IEM diagnosed based on CCv3.0. Further studies are required to determine the implications of these findings on management strategies.

Esophageal hypervigilance and visceral anxiety contribute to symptom severity of laryngopharyngeal reflux. Am J Gastroenterol 2022; 118:786-793. [PMID: 36693025 DOI: 10.14309/ajg.0000000000002151] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Accepted: 11/14/2022] [Indexed: 01/25/2023]
Abstract
OBJECTIVES Laryngopharyngeal reflux (LPR) is a clinical conundrum without a diagnostic gold standard. The esophageal hypervigilance and anxiety scale (EHAS) is a questionnaire designed for cognitive-affective evaluation of visceral sensitivity. We hypothesized that esophageal hypervigilance and symptom-specific anxiety have an etiopathological role in generation of LPR symptoms, especially when gastroesophageal reflux disease (GERD) cannot explain these symptoms. METHODS Consecutive patients with LPR and/or GERD symptoms lasting >3 months were prospectively enrolled and characterized using the reflux symptom index (RSI), GERD questionnaire (GERDQ), and EHAS. Eligible patients with negative endoscopy underwent 24-hour impedance-pH monitoring off acid suppression for phenotyping GERD, and assessment of reflux burden, using conventional metrics [acid exposure time (AET) and number of reflux episodes] as well as novel metrics [mean nocturnal baseline impedance (MNBI) and post-reflux swallow induced peristaltic wave (PSPW) index]. RESULTS Of 269 enrolled patients (mean age 47.1 years, 21-65 years, 60.6% female), 90 patients with concomitant GERD and LPR symptoms, 32 patients with dominant LPR symptoms, 102 patients with dominant GERD symptoms, and 45 controls. Patients with concomitant GERD and LPR symptoms had higher EHAS than those with dominant GERD symptoms and controls. ( P ≤ 0.001); patients with dominant LPR symptoms had higher EHAS than controls. ( P = 0.007). On Pearson's correlation, EHAS positively correlated with RSI. CONCLUSIONS Esophageal hypervigilance symptom-specific anxiety may be more important than reflux burden in LPR symptom perception.

Abstract
Esophageal motility disorders (EMD) may be considered primary disorders only in the absence of gastroesophageal reflux disease (GERD). If GERD is present, treatment should be directed toward correction of the abnormal reflux. The actual prevalence of GERD in manometric dysmotility patterns according to the new Chicago Classification 4.0 (CC4) is still elusive. This study aims to evaluate the prevalence of GERD in patients with esophageal motility disorders according to the CC4. We reviewed 400 consecutive patients that underwent esophageal manometry and pH monitoring. Esophageal motility was classified according to the CC4 and GERD + was defined by a DeMeester score > 14.7. Normal motility or unclassified dysmotility was present in 290 (73%) patients, with GERD+ in 184 of them (63%). There were a total of 110 patients (27%) with named esophageal motility disorders, with GERD+ in 67 (61%). The incidence of ineffective esophageal motility was 59% (n = 65) with 69% GERD +, diffuse esophageal spasm was 40% (n = 44) with 48% GERD +, and hypercontractile esophagus was 0.01% (n = 1) with 100% GERD +. There was no correlation between the presence of GERD and the number of non-peristaltic swallows. Our results show that: (i) manometry only is not enough to select patients' treatment as >60% of patients with named esophageal motility disorders have GERD; (ii) there was no correlation between the presence of GERD and the number of non-peristaltic swallows.

Association of Bolus Transit Time on Barium Esophagram With Esophageal Peristalsis on High-resolution Manometry and Nonobstructive Dysphagia. J Clin Gastroenterol 2022; 56:748-755. [PMID: 34999642 DOI: 10.1097/mcg.0000000000001659] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Accepted: 12/03/2021] [Indexed: 12/10/2022]
Abstract
GOAL The goal of this study was to correlate upright and prone bolus transit time (BTT) on barium esophagography (BE) with esophageal peristalsis on high-resolution manometry (HRM) and self-reported dysphagia in patients with normal lower esophageal sphincter parameters on HRM. BACKGROUND BTT on BE could be the gold standard for assessing the effectiveness of esophageal peristalsis if it can be quantified. MATERIALS AND METHODS Patients with normal lower esophageal sphincter parameters and standard-protocol BE from 2017 to 2020 were included. Patients were divided, based on the number of normal swallows (distal contractile integral >450 mm Hg-s-cm), into 11 groups (10 normal swallows to 0 normal swallows). Liquid barium swallows in prone position were objectively evaluated for prone BTT. Patients reported difficulty in swallowing on a scale from 0 (none) to 4 (very severe). Fractional polynomial and logistic regression analysis were used to study the association (along with the rate of change) between BTT, peristalsis, and dysphagia. RESULTS A total of 146 patients were included. Prone BTT increased as the number of normal swallows decreased ( P <0.001). Two deflection points were noted on the association between peristalsis and prone BTT at 50% normal swallows, 40 seconds and 30% normal swallows, 80 seconds, after which peristaltic function declined independently of prone BTT. Patients with prone BTT>40 seconds had nearly 6-fold higher odds of 0% normal swallows on HRM than patients with prone BTT<40 seconds ( P =0.002). Increasing prone BTT was associated with increasing dysphagia grades 1 and 2 ( P ≤0.036). CONCLUSIONS Esophageal motility can be quantified by BE. Prone BTT correlates with the proportion of normal esophageal swallows and dysphagia.

Am J Physiol Gastrointest Liver Physiol 2022; 323:G145-G156.

Abstract
Esophageal peristalsis consists of initial inhibition (relaxation) followed by excitation (contraction), both of which move sequentially in the aboral direction. Initial inhibition results in receptive relaxation and bolus-induced luminal distension, which allows propulsion by the contraction with minimal resistance to flow. Similar to the contraction wave, luminal distension has unique waveform characteristics in normal subjects; both are modulated by bolus volume, bolus viscosity, and posture, suggesting a possible cause-and-effect relationship between the two. Distension contraction plots in patients with dysphagia with normal bolus clearance [high-amplitude esophageal contractions (HAECs), esophagogastric junction outflow obstruction (EGJOO), and functional dysphagia (FD)] reveal two major findings: 1) unlike normal subjects, there is luminal occlusion distal to bolus during peristalsis in certain patients, i.e., with type 3 achalasia and nonobstructive dysphagia; and 2) bolus travels through a narrow lumen esophagus during peristalsis in patients with HAECs, EGJOO, and FD. Aforementioned findings indicate a relative dynamic obstruction to the bolus flow during peristalsis and reduced distensibility of esophageal wall in the bolus segment of the esophagus. We speculate that a normal or supernormal contraction wave pushing bolus against resistance is the mechanism of dysphagia sensation in significant number of patients. Representations of distension and contraction, combined with objective measures of flow timing and distensibility are complementary to the current scheme of classifying esophageal motility disorders based solely on the characteristics of contraction phase of peristalsis. Better understanding of the distensibility of the bolus-containing segment of the esophagus during peristalsis will lead to the development of novel medical and surgical therapies in the treatment of dysphagia in significant number of patients.

Dysphagia Worsens With Increasing Ineffective Swallows Among Patients With Ineffective Esophageal Motility. J Clin Gastroenterol 2022:00004836-990000000-00045. [PMID: 35960530 DOI: 10.1097/mcg.0000000000001738] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2022] [Accepted: 06/15/2022] [Indexed: 12/10/2022]
Abstract
INTRODUCTION Ineffective esophageal motility (IEM) is the most common motility disorder identified on esophageal high-resolution manometry (HRM), but patients with this finding may be asymptomatic. Therefore, we aimed to identify specific HRM findings predictive of symptoms in IEM. METHODS Adult patients (≥18 y) who underwent HRM between March 2016 and July 2019 were retrospectively evaluated and reclassified according to Chicago Classification 4.0 (CC4.0). Demographic information, HRM parameters, and gastroesophageal reflux disease Health-Related Quality of Life Questionnaire responses were captured among those with normal manometry or IEM. We evaluated the association between heartburn, regurgitation, and dysphagia, with respect to HRM findings including ineffective swallows. RESULTS Of 379 patients, 243 (64.1%) had a normal manometry, 136 (35.9%) were on IEM spectrum, and 73 (19.3%) had conclusive IEM by CC4.0. Mean dysphagia scores were significantly higher in those with conclusive IEM compared with those with normal HRM (2.00 vs. 1.36, P=0.002), as was the percentage of individuals reporting dysphagia affecting daily activities (21.9% vs. 11.4%, P=0.02). Heartburn and regurgitation symptoms did not differ between groups. In a multivariable model of IEM patients, the percentage of ineffective swallows independently predicted a higher dysphagia burden (β regression coefficient: 0.032, P=0.04). CONCLUSIONS Applying the CC4.0 definition for conclusive IEM identifies a group of patients with worse dysphagia symptoms. Within this group, the percentage of ineffective swallows was an independent predictor of dysphagia severity. These findings may help practitioners and patients contextualize the heterogeneous diagnosis of IEM.

Abstract
BACKGROUND Solid bolus swallows (SBS) assess esophageal peristalsis on high-resolution manometry (HRM). It remains unknown if increase in contraction vigor (contraction reserve) following SBS (SBS-CR) provides information similar to that observed following multiple rapid swallows (MRS-CR). METHODS Clinical and HRM data from adult patients (n = 96, age 58.2 years, 61.5% female) undergoing esophageal testing prior to anti-reflux surgery (ARS) were analyzed if both MRS and SBS were available, and compared to similar data from healthy asymptomatic volunteers (n = 18, age 27.5 years, 55.6% female). Patients reported esophageal symptoms before and after ARS using 5-point Likert scales evaluating symptom frequency and severity; scores for each patient were averaged to determine global symptoms. Distal contractile integral (DCI) from single swallows was compared to MRS DCI and SBS DCI; the ratio of single swallow DCI to MRS DCI or SBS DCI ≥1 determined the presence of contraction reserve. KEY RESULTS Multiple rapid swallows CR was concordant with SBS CR in 55.6% of healthy volunteers, 100% of absent contractility, 100% of ineffective esophageal motility (IEM) and 56.9% without IEM. Correlation between MRS DCI and SBS DCI was highest when IEM criteria were met (Spearman's rho 0.998). While neither MRS CR nor SBS CR presence differed by presenting symptoms or global symptom score at baseline, post-ARS global symptom burden was highest in the absence of both MRS CR and SBS CR, especially in patients with esophageal hypomotility using Chicago Classification version 4.0 criteria (p = 0.03). CONCLUSIONS & INFERENCES Multiple rapid swallows and SBS are complementary in predicting post-ARS symptom burden.

Abstract
PURPOSE OF REVIEW Provocative tests have been advocated to address limitations of high-resolution manometry (HRM) with wet swallows. We describe the commonly used provocative manometric manoeuvres [rapid drink challenge (RDC), multiple rapid swallows (MRS), solid swallows and the solid test meal (STM)], compare their diagnostic yield and accuracy to wet swallows, and outline their role in directing clinical management. RECENT FINDINGS Provocative testing with RDC and STM identifies a proportion of achalasia cases missed by standard testing, and RDC can play a similar role to radiology in the evaluation of treatment response. In EGJOO, provocative testing with RDC and STM not only increase the diagnostic yield, but can also help differentiate between spurious cases and those representing true outflow obstruction likely to respond to achalasia-type therapies. MRS and STM can help determine the clinical relevance (or otherwise) of ineffective oesophageal motility, and in this setting, MRS may predict the likelihood of postfundoplication dysphagia. RDC and STM can help identify cases of postfundoplication dysphagia more likely to respond to dilatation. SUMMARY Provocative testing has been shown to increase diagnostic yield of HRM, clarify inconclusive diagnoses, allows corroboration of dysmotility with patient symptoms and helps direct clinical management.

Abstract
BACKGROUND This study aimed to build and evaluate a deep learning, artificial intelligence (AI) model to automatically classify swallow types based on raw data from esophageal high-resolution manometry (HRM). METHODS HRM studies on patients with no history of esophageal surgery were collected including 1,741 studies with 26,115 swallows labeled by swallow type (normal, hypercontractile, weak-fragmented, failed, and premature) by an expert interpreter per the Chicago Classification. The dataset was stratified and split into train/validation/test datasets for model development. Long short-term memory (LSTM), a type of deep-learning AI model, was trained and evaluated. The overall performance and detailed per-swallow type performance were analyzed. The interpretations of the supine swallows in a single study were further used to generate an overall classification of peristalsis. KEY RESULTS The LSTM model for swallow type yielded accuracies from the train/validation/test datasets of 0.86/0.81/0.83. The model's interpretation for study-level classification of peristalsis yielded accuracy of 0.88 in the test dataset. Among model misclassification, 535/698 (77%) swallows and 25/35 (71%) studies were to adjacent categories, for example, normal to weak or normal to ineffective, respectively. CONCLUSIONS AND INFERENCES A deep-learning AI model can automatically and accurately identify the Chicago Classification swallow types and peristalsis classification from raw HRM data. While future work to refine this model and incorporate overall manometric diagnoses are needed, this study demonstrates the role that AI will serve in the interpretation and classification of esophageal HRM studies.

Abstract
Dysphagia is a common symptom with significant impact on quality of life. Our diagnostic armamentarium was primarily limited to endoscopy and barium esophagram until the advent of manometric techniques in the 1970s, which provided the first reliable tool for assessment of esophageal motor function. Since that time, significant advances have been made over the last 3 decades in our understanding of various esophageal motility disorders due to improvement in diagnostics with high-resolution esophageal manometry. High-resolution esophageal manometry has improved the sensitivity for detecting achalasia and has also enhanced our understanding of spastic and hypomotility disorders of the esophageal body. In this review, we discuss the current approach to diagnosis and therapeutics of various esophageal motility disorders.

Abstract
OBJECTIVES Lower esophageal sphincter (LES) plays a key role in gastroesophageal reflux disease (GERD) pathogenesis. In retroflexion and under sufficient insufflation, it can be seen how the lower esophagus grasps the endoscope, which we named scope holding sign (SHS). This study aimed to compare the SHS and LES pressure on high-resolution manometry (HRM), to elucidate whether the sphincter can be visualized endoscopically. METHODS This was a single-center, prospective pilot study. Patients with symptoms of GERD, who underwent endoscopy and HRM between February 2021 and April 2021, were included. A manometry catheter and an ultra-slim endoscope were inserted, and the resting LES pressure was measured. The lower esophagus holding (SHS-positive) and releasing (SHS-negative) the endoscope and catheter were observed. The LES pressures during SHS-positive and SHS-negative were compared. RESULTS Eleven patients (median age: 57 years; eight men) with normal esophageal motility were analyzed. The median LES pressure in SHS-positive was significantly higher than the resting LES pressure (40.4 [22.9-74.0] vs. 25.9 [2.0-66.7] mm Hg; p = 0.001) and the LES pressure in SHS-negative (4.6 [1.5-9.3]; p = 0.001). Furthermore, the LES pressure in SHS-negative was significantly lower than the resting LES pressure (4.6 [1.5-9.3] vs. 25.9 [2.0-66.7] mm Hg; p = 0.005). CONCLUSIONS This study demonstrated that the SHS parallels LES pressure, indicating that the sphincter can be observed endoscopically. This may enable us to evaluate LES function during endoscopy in patients with GERD, thus, deserving further evaluation in future studies.
