The integrated relaxation pressure may not be an appropriate gold standard for deglutitive relaxation due to reliance on a single intragastric reference sensor. Neurogastroenterol Motil 2023; 35:e14635. [PMID: 37357376 PMCID: PMC10906680 DOI: 10.1111/nmo.14635] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/29/2023] [Revised: 06/09/2023] [Accepted: 06/16/2023] [Indexed: 06/27/2023]
Abstract
BACKGROUND Integrated relaxation pressure (IRP) calculation depends on the selection of a single gastric reference sensor. Variable gastric pressure readings due to sensor selection can lead to diagnostic uncertainty. This study aimed to examine the effect of gastric reference sensor selection on IRP measurement and diagnosis. METHODS We identified high-resolution manometry (HRM) conducted between January and November 2017 with at least six intragastric reference sensors. IRP measurements and Chicago Classification 3.0 (CCv3) diagnoses were obtained for each of six gastric reference sensors. Studies were categorized as "stable" (no change in diagnosis) or "variable" (change in diagnosis with gastric reference selection). Variable diagnoses were further divided into "variable normal/dysmotility" (≥1 normal IRP measurement and ≥1 CCv3 diagnosis), or "variable dysmotility" (≥1 CCv3 diagnosis, only elevated IRP measurements). Bland-Altman plots were used to compare IRP measurements within HRM studies. KEY RESULTS The analysis included 100 HRM studies, among which 18% had variable normal/dysmotility, and 10% had variable dysmotility. The average IRP difference between reference sensors was 6.7 mmHg for variable normal/dysmotility and 5.9 mmHg for variable dysmotility. The average difference between the proximal-most and distal-most sensors was -1.52 mmHg (lower limit of agreement -10.03 mmHg, upper limit of agreement 7.00 mmHg). CONCLUSIONS & INFERENCES IRP values can vary greatly depending on the reference sensor used, leading to inconsistent diagnoses in 28% of HRM studies. Choosing the correct gastric reference sensor is crucial for accurate test results and avoiding misdiagnosis. Standardization of reference sensor selection or supportive testing for uncertain results should be considered.

Abstract
BACKGROUND Esophagogastric junction outflow obstruction (EGJOO) is an esophageal motility disorder characterized by a lack of relaxation of the esophagogastric junction (EGJ), with preserved esophageal body peristalsis. We propose new terminology for the coexistence of EGJOO with hypercontractile esophagus and distal esophageal spasm as a major mixed motility disorder (MMMD), and normal peristalsis or a minor disorder of peristalsis such as ineffective esophageal motility with EGJOO as isolated or ineffective EGJOO (IEGJOO). METHODS We reviewed prior diagnoses of EGJOO, stratified diagnoses as IEGJOO or MMMD, and compared their symptomatic presentations, high-resolution manometry (HRM) and endoluminal functional lumen imaging probe (EndoFLIP) metrics, and treatment responses at 2-6 months of follow-up. RESULTS Out of a total of 821 patients, 142 met CCv3 criteria for EGJOO. Twenty-two were confirmed by CCv4 and EndoFLIP as having EGJOO and were clinically managed. Thirteen had MMMD, and nine had IEGJOO. Groups had no difference in demographic data or presenting symptoms by Eckardt score (ES). HRM showed MMMD had greater distal contractile integral, frequency of hypercontractile swallows, and frequency of spastic swallows, and greater DI by EndoFLIP. Patients with MMMD showed greater reduction in symptoms after LES-directed intervention when measured by ES compared with IEGJOO (7.2 vs. 4.0). CONCLUSION Patients with MMMD and IEGJOO present similarly. Detectable differences in HRM portend different responses to endoscopic therapy. Because patients with MMMD have greater short-term prognosis, they should be considered a different diagnostic classification to guide therapy.

Abstract
Introduction Esophagogastric junction outflow obstruction (EGJOO) is attributed to primary/idiopathic causes or secondary/mechanical causes, including hiatal hernias (HH). While patients with HH and EGJOO (HH+EGJOO) may undergo HH repair without myotomy, it is unclear if an underlying motility disorder is missed by therapy which addresses only the secondary EGJOO cause. The goal of this study was to determine if HH repair alone is sufficient management for HH+EGJOO patients. Methods A retrospective review of patients who underwent HH repair between January 1, 2016 and January 31, 2020 was performed. Patients who underwent high-resolution esophageal manometry(HREM) within one year before HH repair were included. Patients with and without EGJOO on pre-operative HREM were compared. Results Sixty-three patients were identified. Pre-operative HREM findings included: 43 (68.3%) normal, 13 (20.6%) EGJOO, 4 (6.3%) minor disorder or peristalsis, 2 (3.2%) achalasia, and 1 (1.6%) major disorder of peristalsis. No differences between patients with EGJOO or normal findings on pre-operative manometry were found in pre-operative demographics/risk factors, pre-operative symptoms, and pre-operative HREM, except higher integrated relaxation pressure in EGJOO patients. No differences were noted in length of stay, 30-day complications, long-term persistent symptoms, or recurrence with mean follow-up of 26-months. Of the 3 (23.1%) EGJOO patients with persistent symptoms, 2 underwent HREM demonstrating persistent EGJOO and none required endoscopic/surgical myotomy. Conclusion Most HH+EGJOO patients experienced symptom resolution following HH repair alone and none required additional intervention to address a missed primary motility disorder. Further study is required to determine optimal management of patients with persistent EGJOO following HH repair.

[PMID: 34864928 PMCID: PMC9016893 DOI: 10.1093/dote/doab077] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/20/2021] [Revised: 11/01/2021] [Indexed: 12/11/2022]
Abstract
BACKGROUND Esophagogastric junction outflow obstruction (EGJOO) has a variable disease course. Currently, barium swallow (BaS) and manometric parameters are used to characterize clinically significant EGJOO. The esophagogastric junction distensibility index (EGJ-DI) measured via functional lumen imaging probe (FLIP) can provide complementary information. Our aim was to assess symptom response in patients with EGJOO and an abnormal EGJ-DI after botulinum toxin (BT) treatment. METHODS A prospective cohort study of adults with idiopathic EGJOO was performed from September 2019 to March 2021. Patients with dysphagia underwent upper endoscopy with FLIP. If the EGJ-DI was abnormally low, BT was injected. Data examined included demographics, medical history, endoscopic and FLIP findings, BaS, manometry, and Eckardt score (ES). ES improvement was assessed via paired samples t-test. Pearson's chi-square tests were used to assess for associations. RESULTS Of the 20 patients, 75% had an abnormal EGJ-DI and underwent BT injections. Mean ES for patients with abnormal EGJ-DIs significantly improved from baseline to 1, 3, and 6 month follow-up (P-values: 0.01, 0.05, and 0.02, respectively). There was a significant association between an abnormal EGJ-DI with delayed bolus transit and presence of rapid drink challenge panesophageal pressurization on manometry: P = 0.03 and P = 0.03. CONCLUSION This prospective study revealed that an abnormal EGJ-DI can guide BT as assessed via symptomatic response. Additionally, abnormal EGJ-DI measurements were significantly associated with other parameters used previously to determine clinically relevant EGJOO. Larger follow-up studies are warranted to further elucidate guidance for therapy in EGJOO.

Predictors of Abnormal Functional Luminal Impedance Planimetry Findings in Non-mechanical Esophagogastric Junction Outflow Obstruction. Dig Dis Sci 2021; 66:3968-3975. [PMID: 33249528 PMCID: PMC8248766 DOI: 10.1007/s10620-020-06726-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/28/2020] [Accepted: 11/17/2020] [Indexed: 12/25/2022]
Abstract
BACKGROUND Esophagogastric junction outflow obstruction (EGJOO) is a common but nonspecific motility pattern identified by esophageal high-resolution manometry (HRM). Functional luminal impedance planimetry (FLIP) provides information regarding lower esophageal sphincter (LES) mechanics, which can identify achalasia spectrum disorders and is useful in evaluating EGJOO. However, the relationship between HRM and FLIP parameters in EGJOO is not clearly defined. AIMS To identify predictors of abnormal FLIP findings in patients with non-mechanical EGJOO. METHODS This is a retrospective cohort study of patients with non-mechanical EGJOO who underwent FLIP between 10/1/16 and 7/1/19. Demographic data including age and gender, examination indication, concomitant medications, HRM parameters, symptom burden, and FLIP metrics of diameter and distensibility index (DI) were collected. DI was categorized as not low (DI > 2.8), borderline low (DI 1.1-2.8), and definitely low (DI ≤ 1). Kruskal-Wallis and Fisher's exact tests were used to assess the relationship between HRM and FLIP parameters and to identify predictors of abnormal FLIP. RESULTS Among the 44 patients studied, most were female (n = 33, 75%) and the median age was 63. The median IRP was 18.2, and 10 (23%) patients used chronic narcotics. Lower total heartburn and regurgitation scores, and LES diameter by FLIP are associated with definitely low DI. CONCLUSIONS In patients with non-mechanical EGJOO, reflux burden scores and FLIP diameters can aid in predicting DI. These results may provide useful adjunctive data to help in differentiating which patients have meaningful outflow obstruction.

Abstract
In the Chicago Classification version 4.0 (CCv4), esophagogastric junction outflow obstruction (EGJOO) is manometrically defined as an elevated median integrated relaxation pressure (IRP) and elevated intrabolus pressure (IBP) during supine wet swallows, and persistently elevated median IRP in the upright position. A clinically relevant conclusive diagnosis of EGJOO requires a manometric diagnosis of EGJOO and associated symptoms such as dysphagia and/or chest pain with at least one of the following supportive investigations (pharmacologic provocation, timed barium esophagogram, and/or endoflip). The Chicago Classification is intended for diagnosis of primary esophageal motor disorders, and thus history and endoscopic evaluation are important to exclude conditions (eg, previous surgery, strictures, or masses) that can secondarily generate the EGJOO pattern on HRM. While a manometric finding of EGJOO is often made and can be an early sign of achalasia, more often it is a manometric finding without clinical implications. The proposed changes in CC4.0 have attempted to make the diagnosis more specific, in order to reduce the number of clinically irrelevant diagnoses and avoid confusion by patients and physicians alike.

Abstract
Background/Aims Esophagogastric junction outflow obstruction (EGJOO) is characterized by elevated integrated relaxation pressure (IRP) and preserved esophageal peristalsis. The clinical significance of EGJOO is uncertain. This study aim to describe the clinical characteristics of these patients and to find out potential parameters to predict patients’ symptom outcome. Methods Consecutive patients who received high-resolution manometry examination in our hospital in 2013-2019 and met the diagnostic criteria of EGJOO were retrospectively included. Motility and reflux parameters as well as endoscopy and barium esophagogram results were studied and compared. Patients were also followed up to record their treatment methods and symptom outcomes. Results A total of 138 EGJOO (accounting for 5.2% of total patients taking high-resolution manometry examination in our hospital) patients were included. Only 2.9% of these patients had persistent dysphagia. A total of 81.8% of EGJOO patients had symptom resolution during follow-up. Patients with persistent dysphagia had significantly higher upright IRP (16.6 [10.3, 19.8] vs 7.8 [3.2, 11.5]; P = 0.026) than those without. Upright IRP can effectively distinguished patients with persistent dysphagia (area under curve 0.826; P = 0.026) using optimal cut-off value of 9.05 mmHg. Conclusion EGJOO patients with persistent dysphagia and higher upright IRP (median > 9.05 mmHg) needs further evaluation and aggressive management.

Coexisting Abnormal Esophageal Body Motility Predicts Clinical Symptoms and Bolus Transit in Patients With Esophagogastric Junction Outflow Obstruction (EGJOO). J Clin Gastroenterol 2021; 55:499-504.

Abstract
GOAL The goal of this study was to compare the clinical presentations of esophagogastric junction outflow obstruction (EGJOO) with coexisting abnormal esophageal body motility (EBM) to isolated EGJOO. BACKGROUND The clinical significance and management of EGJOO remain debated, as patients may have varied to no symptoms. The effect of coexisting abnormal EBM in EGJOO is unclear. We hypothesized that a concomitant EBM disorder is associated with clinical symptoms of EGJOO. STUDY This was a retrospective cohort study of consecutive adults diagnosed with EGJOO on high-resolution impedance-manometry (HRIM) at 2 academic centers in March 2018 to September 2018. Patients with prior treatment for achalasia, foregut surgery, or evidence of obstruction were excluded. Subjects were divided into EGJOO with abnormal EBM per Chicago classification v3.0 and isolated EGJOO. Statistical analyses were performed using Fisher-exact or Student t test (univariate) and logistic or linear regression (multivariate). RESULTS Eighty-two patients (72% women, age 61.1±10.7 y) were included. Thirty-one (37.8%) had abnormal EBM, including 16 (19.5%) ineffective esophageal motility and 15 (18.2%) hypercontractile esophagus. Esophageal symptoms (heartburn, regurgitation, chest pain, dysphagia) were more prevalent among those with abnormal EBM (90.3% vs. 64.7%, P=0.01). On logistic regression adjusting for age, gender, body mass index, and opioid use, abnormal EBM remained predictive of esophageal symptoms (adjusted odds ratio [aOR] 7.51, P=0.007). On separate models constructed, HE was associated with chest pain (aOR 7.45, P=0.01) and regurgitation (aOR 4.06, P=0.046), while ineffective esophageal motility was predictive of heartburn (aOR 5.84, P=0.009) and decreased complete bolus transit (β-coefficient -0.177, P=0.04). CONCLUSION Coexisting abnormal EBM is associated with esophageal symptoms and bolus transit in patients with EGJOO.

Abstract
PURPOSE OF REVIEW Esophagogastric junction outflow obstruction (EGJOO), defined as elevated integrated residual pressure (IRP) with preservation of esophageal peristalsis, is a common finding on high-resolution esophageal manometry. RECENT FINDINGS The recent Chicago classification version 4.0 proposes changes to the criteria for diagnosing EGJOO, making this diagnosis more restrictive to now include elevated IRP in both supine and upright positions (with preservation of esophageal peristalsis), presence of obstructive symptoms, and confirmatory tests for EGJOO, such as timed barium esophagram with barium tablet or functional lumen imaging probe. SUMMARY Once the diagnosis of EGJOO is established, secondary causes need to be ruled out, especially the use of opioid medications. Upper endoscopy is needed for evaluation of EGJOO patients, though cross-sectional imaging is usually not necessary. Many patients improve without intervention; thus, expectant management is recommended for patients with mild or atypical symptoms. There seems to be a limited role for medical treatment. Botox injection into the lower esophageal sphincter is often used to see if the patient improves before committing to more definitive treatments, such as pneumatic dilation, peroral endoscopic myotomy, or Heller myotomy.

Abstract
GOALS The authors aimed to compare preperistaltic distal esophageal pressure in patients with esophagogastric junction outflow obstruction (EGJOO) with and without reported dysphagia. BACKGROUND Manometric EGJOO is characterized by elevated integral relaxation pressure (>15 mm Hg) without achalasia. The nomenclature inherently implies that it should be associated with impaired food bolus transit and should theoretically present clinically as dysphagia. STUDY The authors queried an esophageal functional test database to identify patients diagnosed with EGJOO. They excluded patients who presented with ≥2 swallows with abnormal (ie, weak, failed or hypercontractile) esophageal body motility. To elucidate differences in manometric findings, the authors formed 2 cohorts of patients on the basis of a standard esophageal symptom questionnaire: those without dysphagia and those with severe or very severe dysphagia. All studies were reanalyzed to determine the distal esophageal pressure before each peristaltic wave (ie, the preperistaltic pressure) for individual swallows. The Mann-Whitney U test was used to compare categorical variables between groups. The level of significance was set to P<0.05. RESULTS In total, 149 patients were diagnosed with EGJOO during the study period. Of these, 42 patients with ≥9 (out of 10) peristalsis (20 without dysphagia and 22 with severe/very severe dysphagia) formed the study cohorts. Patients with severe dysphagia had significantly higher median preperistaltic pressures in the distal esophagus. Preperistaltic pressure measurements showed better sensitivity and specificity for dysphagia than integral relaxation pressure. CONCLUSIONS Elevated preperistaltic pressure is noted in symptomatic EGJOO patients. Inclusion of preperistaltic pressure in the diagnostic criteria for EGJOO may increase the clinical relevance of manometric classification.

Abstract
BACKGROUND The treatment of esophagogastric junction outflow obstruction (EGJOO) currently mirrors that of achalasia, but this is based on only a few studies on small case series. The aim of this prospective, controlled study was to assess the outcome of laparoscopic Heller-Dor (LHD) in patients with EGJOO, as compared with patients with esophageal achalasia. MATERIALS AND METHODS Between 2016 and 2019, patients with manometric diagnosis of idiopathic EGJOO and patients with radiological stage I achalasia, both treated with LHD, were compared. The achalasia group was further analyzed by subgrouping the patients based on the manometric pattern. Treatment failure was defined as the persistence or reoccurrence of an Eckardt score > 3 or the need for retreatment. RESULTS During the study period, 150 patients were enrolled: 25 patients had EGJOO and 125 had radiological stage I achalasia (25 pattern I, 74 pattern II, and 26 pattern III). The median follow-up was 24 months (IQR: 34-16). Treatment was successful in 96% of patients in the EGJOO group and in 96% of achalasia patients with pattern I, 98.7% in those with pattern II, and 96.2% of those with pattern III (p=0.50). High-resolution manometry showed a reduction in the LES resting pressure and integrated relaxation pressure for all patients in all 4 groups (p<0.001). CONCLUSION This is the first comparative study based on prospective data collection to assess the outcome of LHD in patients with EGJOO. LHD emerged as an effective treatment for EGJOO, with an excellent success rate, comparable with the procedure's efficacy in treating early-stage achalasia.

Esophageal peroral endoscopic myotomy (POEM) for treatment of esophagogastric junction outflow obstruction: results from the first prospective trial. Endosc Int Open 2020; 8:E1137-E1143. [PMID: 32904698 PMCID: PMC7458721 DOI: 10.1055/a-1198-4643] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2020] [Accepted: 05/11/2020] [Indexed: 12/16/2022] Open
Abstract
Background and study aims Esophagogastric junction outflow obstruction (EGJOO) is a rare esophageal dysmotility disease that is characterized by elevated integrated relaxation pressuse (IRP) with evidence of preserved peristalsis. The role of peroral endoscopic myotomy (POEM) in management of EGJOO is currently unknown. Patients and methods This is a prospective trial conducted in a single US tertiary care center from June 2015 to June 2019. Symptomatic patients, diagnosed with EGJOO on both HRM and endoluminal functional lumen imaging probe (EndoFLIP), who were eligible for POEM were recruited. Primary outcome was clinical success, defined as Eckardt score (ES) ≤ 3, at 6 months post-POEM. Other outcomes included dysphagia score, quality of life as measured by 36-item Short Form health survey scales (SF-36), post-POEM HRM, EndoFLIP, and pH measurements, and adverse events. Results A total of 15 patients (51.8 yr. 9 F) with EGJOO underwent POEM. Pre-POEM mean IRP on HRM and Distensibility index (DI) on EndoFLIP were 24.3 ± 2.2 mmHg and 1.1 ± 0.6 mm 2 /mmHg, respectively. Clinical success was achieved in 93 % at 6 months post-POEM. There was significant decrease in IRP (-17.6 mmHg) post-POEM. There was significant improvement at 6 months in two of the SF-36 subscales. Ten patients underwent post-POEM pH testing, seven of whom had abnormal DeMeester score. Seven patients underwent EGD evaluation revealing esophagitis in five (2 Los Angeles grade A and 3 grade B). Conclusions POEM offers a high clinical success rate for patients with EGJOO confirmed by impedance planimetry.

Abstract
OBJECTIVE To determine the differences between clinical, manometric, and neuroimmunological profile of esophagogastric junction outflow obstruction (EGJOO) and achalasia patients. METHODS Seven EGJOO and 27 achalasia patients were enrolled in a blind cross-sectional study. Peripheral blood (PB) of 10 healthy donors and 10 lower esophageal sphincter (LES) muscle biopsies from organ transplant donors were included as controls. The presence of ganglion cells, cells of Cajal, Th22/Th7/Th2/Th1/Tregs/Bregs/pDCregs in tissue, and PB was assessed by immunohistochemistry and flow cytometry. Serum concentration of IL-22/IL-17A/IL-17F/IL-4/IFN-γ/IL-1β/IL-6/IL-23/IL-33/TNF-α/IL-10 was determined using bioplex plates. ANAs and antineuronal antibodies were evaluated by immunofluorescence and Western blot. KEY RESULTS EGJOO and achalasia patients had lower ganglion cells and cells of Cajal percentage vs. controls, while fibrosis was present only in achalasia patients. EGJOO and controls had lower cell percentage of Th22/Th17/Th2 vs. achalasia. EGJOO tissue had lower Th1/Treg cell number vs. achalasia, but higher levels vs. control group. Bregs and pDCregs percentage was higher in EGJOO vs. control group. Percentage of PB subpopulations in EGJOO was not significantly different from control group. Serum cytokine levels were higher for IL-1β/IL-6/TNF-α, while IL-17A levels were lower in EGJOO vs. achalasia and control group. EGJOO group was negative for ANAs, while in achalasia group, 54% were positive. GAD65 and PNMa/Ta2 antibodies were present in achalasia, whereas Yo and recoverin were positive in EGJOO group. CONCLUSIONS AND INFERENCES Although EGJOO shares some clinical characteristics with achalasia, the neuroimmunological profile is completely different, suggesting that EGJOO might be a different entity.

Abstract
Esophagogastric junction outflow obstruction (EGJOO) is an abnormal topographic pattern seen on high-resolution manometry. EGJOO is characterized by an elevated median integrated relaxation pressure with intact or weak peristalsis, thus not meeting the criteria for achalasia. This diagnosis has a female predominance and is associated with varying presenting symptoms. EGJOO can be idiopathic or secondary. It is important to assess for secondary causes, including structural or medication-related ones. Cross-sectional imaging is recommended to rule out secondary causes; however, increasing evidence suggests that esophagogastroduodenoscopy and barium esophagram are usually sufficient. The disease course is variable, with up to three-quarters of patients experiencing spontaneous resolution of symptoms over 6 months. In patients who have mild symptoms, it is reasonable to observe and consider treatment if symptoms persist. Variable response has been seen in small studies with both medical treatment and botulinum toxin injection of the lower esophageal sphincter. For patients with significant symptoms and objective evidence of obstruction on imaging, targeted therapy of the lower esophageal sphincter should be considered via pneumatic dilation or myotomy.

Abstract
PURPOSE OF REVIEW High resolution esophageal manometry (HRM) has expanded understanding of esophageal motor function. The Chicago Classification scheme has allowed systematic categorization of the myriad of manometric parameters identified during HRM. Multichannel intraluminal impedance pH has enhanced ambulatory reflux monitoring through complete assessment of esophageal content transit. However, the clinical implications of identified minor esophageal functional disorders remain unclear. RECENT FINDINGS Esophagogastric junction outlet obstruction is defined by esophagogastric junction obstruction with preserved peristalsis and may be managed expectantly, or in a manner similar to achalasia. Hypercontractile esophagus has been associated with dysphagia and non-cardiac chest pain, but the clinical significance is unclear as a majority of patients will improve without specific therapy. Additionally, these findings may be confounded by chronic opiate use. Ineffective esophageal motility is characterized by diminished esophageal contraction amplitude, potentially causing dysphagia and GERD. However, this is commonly identified in asymptomatic volunteers and may represent a normal variant. The multiple rapid swallow sequence can assess esophageal contraction reserve, which may predict post fundoplication dysphagia. The post-swallow induced peristaltic wave can serve as a surrogate of gastric refluxate clearance, providing important prognostic value. However, the associated time burden and lack of alternative therapeutic options limit its clinical utility. SUMMARY Minor esophageal functional disorders provide new therapeutic targets for symptomatic patients. However, these findings have inconsistent associations with symptoms and poorly defined therapeutic options. Minor esophageal function disorders should not be interpreted in isolation, with management decisions accounting for clinical, endoscopic, and radiographic factors in addition.

Abstract
PURPOSE OF REVIEW We summarize the current epidemiology, presentation, diagnostic workup, and treatment of esophagogastric junction outflow obstruction (EGJOO). We also propose a treatment algorithm based upon the literature and our personal clinical experience. RECENT FINDINGS EGJOO can be caused by functional obstruction (akin to achalasia), mechanical obstruction, medications, or artifact. High-resolution esophageal manometry is currently the gold standard of diagnosis. Recent research on FLIP (functional lumen imaging probe) and timed barium support use as adjunctive testing. The diagnostic yield of cross-sectional imaging is low. Current diagnostic testing and treatment should be targeted to the suspected underlying etiology and clinical presentation of EGJOO. If functional obstruction is present with significant and persistent dysphagia, and either an abnormal FLIP or timed barium swallow, we consider therapy aimed at LES disruption (similar to achalasia). Pharmacologic therapy has a limited role. More research is needed on diagnostic and treatment modalities.

Abstract
AIM To systematically review clinical presentation, diagnosis, and therapy of achalasia, focusing on recent developments in high-resolution esophageal manometry (HREM) for diagnosis and peroral endoscopic myotomy (POEM) for therapy. METHODS Systematic review of achalasia using computerized literature search via PubMed and Ovid of articles published since 2005 with keywords ("achalasia") AND ("high resolution" or "HREM" or "peroral endoscopic myotomy" or "POEM"). Two authors independently performed literature searches and incorporated articles into this review by consensus according to prospectively determined criteria. RESULTS Achalasia is an uncommon esophageal motility disorder, usually manifested by dysphagia to solids and liquids, and sometimes manifested by chest pain, regurgitation, and weight loss. Symptoms often suggest more common disorders, such as gastroesophageal reflux disease (GERD), thus often delaying diagnosis. Achalasia is a predominantly idiopathic chronic disease. Diagnosis is typically suggested by barium swallow showing esophageal dilation; absent distal esophageal peristalsis; smoothly tapered narrowing ("bird's beak") at esophagogastric junction; and delayed passage of contrast into stomach. Diagnostic findings at high-resolution esophageal manometry (HREM) include: distal esophageal aperistalsis and integrated relaxation pressure (trough LES pressure during 4 s) > 15 mmHg. Achalasia is classified by HREM into: type 1 classic; type 2 compartmentalized high pressure in esophageal body, and type 3 spastic. This classification impacts therapeutic decisions. Esophagogastroduodenoscopy is required before therapy to assess esophagus and esophagogastric junction and to exclude distal esophageal malignancy. POEM is a revolutionizing achalasia therapy. POEM creates a myotomy via interventional endoscopy. Numerous studies demonstrate that POEM produces comparable, if not superior, results compared to standard laparoscopic Heller myotomy (LHM), as determined by LES pressure, dysphagia frequency, Eckardt score, hospital length of stay, therapy durability, and incidence of GERD. Other therapies, including botulinum toxin injection and pneumatic dilation, have moderately less efficacy and much less durability than POEM. CONCLUSION This comprehensive review suggests that POEM is equivalent or perhaps superior to LHM for achalasia in terms of cost efficiency, hospital length of stay, and relief of dysphagia, with comparable side effects. The data are, however, not conclusive due to sparse long-term follow-up and lack of randomized comparative clinical trials. POEM therapy is currently limited by a shortage of trained endoscopists.

Abstract
BACKGROUND The Chicago Classification of esophageal motility includes a group of patients who show evidence of esophagogastric junction outflow obstruction (EGJOO) as demonstrated by elevated integrated relaxation pressure (IRP) and preserved peristalsis. Our aim is to classify EGJOO patients based on response to amyl nitrite (AN) during high-resolution manometry. METHODS Patients were considered to have true EGJOO if elevated IRP during supine swallow persisted in the upright position and was associated with high intrabolus pressure. The EGJ response to AN was compared between patients with achalasia type 2 (A2) and normal esophageal motility. Based on the relaxation gain (deglutitive IRP-AN IRP) value that best discriminated these two groups (10 mm Hg), patients with true EGJOO were categorized as being in either the AN-responsive (AN-R) or AN-unresponsive (AN-U) subgroups. KEY RESULTS In the group of 49 patients with true EGJOO, the AN response classified 27 patients (IRP = 25 ± 10 mm Hg) with AN-R and 22 patients (IRP = 20 ± 5 mm Hg) with AN-U (P = 0.2). In AN-R, AN produced a relaxation gain and rebound after-contraction response at the EGJ comparable to A2 patients. AN-U patients had an elevated IRP after AN and a relaxation gain similar to normal esophageal motility patients. AN-U patients were obese and had higher prevalence of sleep apnea (P < 0.05). CONCLUSIONS Among patients with true EGJOO, only half have pharmacologic evidence of impaired LES relaxation. Pharmacologic interrogation of the EGJ is thus necessary to identify the subgroup of EGJOO patients who could be expected to benefit from LES ablative therapies.

Abstract
Introduction Axial hiatal hernias are a common incidental finding in endoscopical examinations, but reflux symptoms do not necessarily correspond to the presence of hiatal hernias. Diagnosing a reflux disease is difficult due to a leak of existing distinct criteria, especially in order to evaluate a surgical indication. Also a preoperative measurement of the hernia is necessary to choose between surgical options. Methods and analysis We planned a semiblinded trial including a questionnaire and an oesophagogastroduodenoscopy afterwards. While the endoscopy is done, the hiatus oesophagi should be measured in inversion technique under maximum insufflation including length, width and herniated volume. A sample of 210 participants until December 2020 is determined to evaluate the primary endpoint: we look forward to evaluate the anatomical parameters of reflux and non-reflux participants. Ethics and Dissemination The study has been approved by the local ethics committee on 12th February 2019, the data will bei published after closure of inclusion. Trial registration number German Clinical Trials Register (DRKS00016863).
