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
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
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.

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. [PMID: 32649446 DOI: 10.1097/mcg.0000000000001390] [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: 04/21/2020] [Accepted: 06/04/2020] [Indexed: 12/10/2022]
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
INTRODUCTION AND AIMS Post-fundoplication dysphagia is resolved with no therapeutic intervention in the majority of cases but it can persist in 5.3% of children that undergo the procedure. Among the differential diagnoses, esophagogastric junction outflow obstruction (EGJOO) is a disorder that should be suspected if there is a persistence of dysphagia. The aim of our study was to describe the clinical characteristics, treatment, and follow-up in a case series of patients diagnosed with post-fundoplication EGJOO. MATERIALS AND METHODS The clinical records of patients diagnosed with EGJOO at a tertiary care hospital within the time frame of September 2015 to September 2019 were reviewed, with respect to manometry, etiology, treatment, and clinical course of the disease. RESULTS Of the 213 high-resolution esophageal manometries performed, 4 patients met the criteria for post-fundoplication EGJOO. The primary symptom was dysphagia, presenting 15 days after the procedure. Esophageal dilations were carried out on all the patients but with no improvement. Symptoms related to the condition resolved spontaneously in three of the four patients. CONCLUSION The management of children with post-fundoplication EGJOO continues to be a challenge. Even though more than half of the cases resolve with no intervention, optimum management of the motility disorder is still limited, given the scant experience with the condition in the pediatric population.

Abstract
INTRODUCTION Patients with esophageal symptoms often remain with an uncertain diagnosis after high-resolution manometry. AIM To determine the added value of concomitant pressure and symptom analysis in response to a rapid drink challenge (RDC). METHODS In consecutive patients referred for esophageal manometry, a RDC consisting in free drinking of 200 ml of water as quick as possible was performed after the standard single water swallows manometry. Both pressure patterns and usual symptoms induced by the RDC were analyzed. RESULTS A total of 1319 patients were included, (64.7% women, mean age 58.2 years, range 11-90). There were significant differences in pressure responses between patients with obstructive disorders, major hypercontractile disorders, esophageal hypomotility disorders and normal motility. The RDC provoked usual symptoms in 388 (29.4%) patients, associated with hyperpressive and obstructive patterns in 14.0% and 16.6%, respectively. Reproduction of dysphagia and regurgitation (not pain) was significantly associated with abnormal pressure responses during the RDC (p < 0.001 and p = 0.002, respectively). The RDC elicited both abnormal pressure patterns and symptoms in 6.2%, 1.6%, and 20.8% of patients with normal motility, ineffective esophageal motility, and esophago-gastric junction outflow obstruction, respectively. CONCLUSION Concomitant evaluation of symptoms and pressure responses to a RDC may increase the specificity of esophageal motor testing in patients with inconclusive diagnosis or normal esophageal motility.

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
PURPOSE OF REVIEW Esophageal peristalsis is a highly sophisticated function that involves the coordinated contraction and relaxation of striated and smooth muscles in a cephalocaudal fashion, under the control of central and peripheral neuronal mechanisms and a number of neurotransmitters. Esophageal peristalsis is determined by the balance of the intrinsic excitatory cholinergic, inhibitory nitrergic and post-inhibitory rebound excitatory output to the esophageal musculature. RECENT FINDINGS Dissociation of the longitudinal and circular muscle contractions characterizes different major esophageal disorders and leads to esophageal symptoms. Provocative testing during esophageal high-resolution manometry is commonly employed to assess esophageal body peristaltic reserve and underpin clinical diagnosis. Herein, we summarize the main factors that determine esophageal peristalsis and examine their role in major and minor esophageal motility disorders and eosinophilic esophagitis.

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
BACKGROUND/AIMS Esophagogastric junction outflow obstruction (EGJOO) is a diagnostically heterogeneous group with variable clinical relevance. We studied whether evaluation of bolus transit by multichannel intraluminal impedance (MII) is useful for discriminating clinically relevant EGJOO. METHODS A total 169 patients diagnosed as having EGJOO between June 2011 and February 2018 were analyzed. All the patients received a combined MII and high-resolution manometry (CMII-HRM). MII was reported as having abnormal liquid bolus transit (LBT) if < 80% of swallows had complete bolus transit. EGJOO was defined as a median integrated relaxation pressure of > 20 mmHg and when the criteria for achalasia were not met. Patients who progress to achalasia, show significant passage disturbance, or require pneumatic dilatation were defined as having a clinically relevant EGJOO. RESULTS Among the patients with EGJOO (n = 169), the clinically relevant group (n = 10) is more likely to have dysphagia (100% vs 25.2%, P < 0.001), compartmentalized pressurization (CP; 90.0% vs 22.0%, P < 0.001), and abnormal LBT (100% vs 66.7%, P = 0.032) compared to the non-relevant group (n = 159). The combination of dysphagia, CP, and abnormal LBT showed the best predictive power for clinically relevant EGJOO (sensitivity 90%, specificity 92.5%, positive predictive value 42.9%, negative predictive value 99.3%, positive likelihood ratio 11.9, and negative likelihood ratio 0.1). When CMII-HRM was used, an additional 8.3% of clinically relevant EGJOO cases were identified as compared with HRM alone. CONCLUSION Clinically relevant EGJOO can be predicted using CMII-HRM.

Abstract
Background/Aims Swallows with viscous or solid boluses in different body positions alter esophageal manometry patterns. Limitations of previous studies include lack of standardized viscous substrates and the need for chewing prior to swallowing solid boluses. We hypothesize that high-resolution impedance manometry (HRiM) using standardized viscous and super-viscous swallows in supine and upright positions improves sensitivity for detecting esophageal motility abnormalities when compared with traditional saline swallows. To establish normative values for these novel substrates, we recruited healthy volunteers and performed HRiM. Methods Standardized viscous and super-viscous substrates were prepared using “Thick-It” food thickener and a rotational viscometer. All swallows were administered in 5-mL increments in both supine and upright positions. HRiM metrics and impedance (bolus transit) were calculated. We used a paired two-tailed t test to compare all metrics by position and substrate. Results The 5-g, 7-g, and 10-g substrates measured 5000, 36 200, and 64 700 mPa sec, respectively. In 18 volunteers, we observed that the integrated relaxation pressure was lower when upright than when supine for all substrates (P < 0.01). The 10-g substrate significantly increased integrated relaxation pressure when compared to saline in the supine position (P < 0.01). Substrates and positions also affected distal contractile integral, distal latency, and impedance values. Conclusions We examined HRiM values using novel standardized viscous and super-viscous substrates in healthy subjects for both supine and upright positions. We found that viscosity and position affected HRiM Chicago metrics and have potential to increase the sensitivity of esophageal manometry.

[PMID: 30073090 PMCID: PMC6067397 DOI: 10.1136/bmjgast-2018-000210] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2018] [Revised: 04/28/2018] [Accepted: 05/01/2018] [Indexed: 01/21/2023] Open
Abstract
Background The Chicago Classification (CC) defines oesophagogastric junction outflow obstruction (EGJOO) as the presence of an elevated integrated residual pressure (IRP) together with preserved oesophageal body peristalsis but its clinical significance is evolving. Aims To describe the clinical and manometric characteristics in patients with EGJOO and propose a new classification. Methods In this retrospective cohort study, patients with functional oesophageal symptoms underwent clinical and endoscopic assessment and oesophageal high-resolution manometry (HRM). The CC V.3 was used to define and redefine abnormalities. Results Of 478 HRM studies performed, EGJOO, defined as median IRP >15 mm Hg, was diagnosed in 116 patients; 17 underwent a follow-up HRM. Forty-four patients had otherwise normal oesophageal motility, with the only finding being EGJOO; 14 had achalasia, 19 had EGJOO plus ineffective oesophageal motility (IEM), 28 had EGJOO plus diffuse oesophageal spasm (DES) (n=25) or jackhammer oesophagus (n=3), and 11 had EGJOO plus IEM and DES. Patients with EGJOO+IEM had lower distal contractile integral (DCI) while those with EGJOO+DES had higher DCI. All groups exhibited high percentages of incomplete bolus clearance. On repeat studies, EGJOO preceded or followed another HRM diagnosis and remained permanent in 2/17 patients. Only one patient transitioned to achalasia. Conclusions The new classification further defines EGJOO by considering abnormalities in the body of the oesophagus that could contribute to symptoms or require therapy. Most patients with EGJOO have a coexisting motility disorder and do not have isolated EGJOO. There is a fluidity of the HRM diagnosis that needs to be considered prior to therapy.
