Abstract
Esophagogastric junction outflow obstruction (EGJOO) is a rapidly evolving diagnosis that can represent early or variant achalasia. Since the publication of the Chicago Classification version 4.0, the criteria for this diagnosis have been more stringent. Currently, the criteria include an elevated median integrated relaxation pressure (IRP) in both the supine and upright positions, elevated intrabolus pressure in at least 20% of supine swallows, dysphagia and/or chest pain, as well as an abnormal timed barium esophagram and/or impedance planimetry testing. Additionally, other secondary causes may result in an elevated IRP and must be excluded. The management of conclusive EGJOO is targeted therapy to the lower esophageal sphincter (LES), although treatment is not straightforward. Overall, adjuvant testing and data should be scrutinized for appropriateness of LES disruption. The spectrum of treatment options includes simple monitoring as well as more invasive therapies such as endoscopic dilation and myotomy. This article explores the newest criteria and management options for clinically relevant EGJOO.

Dysphagia 2024:10.1007/s00455-023-10655-1.

Abstract
Integrated Residual Pressure (IRP) measured under conditions alternative to supine single swallows may provide clinically useful information regarding EGJ relaxation. This study aimed to compare IRP values obtained under different situations and explore their potential clinical utility. We analyzed and compared the values of IRP obtained from healthy volunteers and patients with suspected achalasia during supine single swallows (Ssup-IRP), sitting single swallows (Ssit-IRP), supine multiple rapid swallows (Msup-IRP), and sitting multiple rapid swallows (Msit-IRP). We analyzed the HREM recordings of 40 healthy volunteers and 53 patients with suspected achalasia. The four metrics were significantly different from each other in healthy volunteers (Ssup-IRP > Msup-IRP > Ssit-IRP > Msit-IRP) and their corresponding 95th percentiles were substantially distinct (Ssup-IRP: 25.3 mmHg, Ssit-IRP: 20.9 mmHg, Msup-IRP: 15.9 mmHg, and Msit-IRP: 11.9 mm Hg, respectively). Complete agreement among the four metrics in predicting abnormal IRP was found in 39 of the 47 patients with suspected achalasia who completed the protocol. Optimal cutoffs derived from ROC curve analysis demonstrated ≥ 0.95 specificities for detection of impaired EGJ relaxation among patients with suspected achalasia. Among the eight patients with suspected achalasia with normal Ssup-IRP, five demonstrated abnormal Msit-IRP and four abnormal Ssit-IRP. Significant differences of IRP exist depending on the measurement situation, indicating that correct interpretation of IRP values requires specific cutoffs for each situation.The sensitivities of Ssit-IRP and Msit-IRP in detecting defective EGJ relaxation appear to be slightly higher than that of Ssup-IRP.

Esophagogastric Junction Outflow Obstruction Is Likely to Be a Local Manifestation of Other Primary Diseases: Analysis of Single-Center 4-Year Follow-Up Data. Diagnostics (Basel) 2023; 13:2329. [PMID: 37510073 PMCID: PMC10378678 DOI: 10.3390/diagnostics13142329] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Revised: 06/08/2023] [Accepted: 06/30/2023] [Indexed: 07/30/2023] Open
Abstract
BACKGROUND Whether esophagogastric junction outflow obstruction (EGJOO) is a variant of achalasia cardia (AC) or an esophageal motility state of certain organic or systemic diseases remains controversial. We aimed to investigate the differences between EGJOO and AC in clinical characteristics and outcomes through a 4-year follow-up. METHODS Patients diagnosed with primary EGJOO or AC were included. Based on the presence of concomitant disease, EGJOO patients were divided into a functional and an anatomical EGJOO group; similarly, patients with AC were divided into an AC with organic disease group and a true AC group. Disease characteristics and high-resolution manometry (HRM) parameters were retrospectively compared between the groups, and the development of organic diseases that could affect esophageal motility disorders and responses to treatment were examined during the follow-up. Symptom relief was defined as an Eckardt score of ≤3 after the treatment. RESULTS The study included 79 AC patients and 70 EGJOO patients. Compared with patients with AC, EGJOO patients were older, had shorter disease duration, a lower Eckardt score, and were more likely to have concurrent adenocarcinoma of the esophagogastric junction (AEG) and autoimmune disease (p < 0.05 for all). The severity of dysphagia and Eckardt scores were higher in the anatomical EGJOO group than in the functional EGJOO group. Significant differences were seen in HRM parameters (UES residual pressure, LES basal pressure, and LES residual pressure) between AC and EGJOO patients. However, no significant differences in HRM parameters were observed between the functional EGJOO and anatomical EGJOO groups. Sixty-seven (95.71%) patients with EGJOO and sixty-nine (87.34%) patients with AC experienced symptom relief (p = 0.071). Among patients achieving symptom relief, a relatively large proportion of patients with EGJOO had symptom relief after medications (37/67, 55.22%), the resolution of potential reasons (7/67, 10.45%), and spontaneous relief (15/67, 22.39%), while more patients with AC had symptom relief after POEM (66/69, 95.65%). Among EGJOO patients achieving symptom relief, more patients (7/20, 35%) with anatomical EGJOO had symptom relief after the resolution of potential reasons for EGJOO, while more patients (32/47, 68.09%) with functional EGJOO had symptom relief with medications. CONCLUSIONS Concurrent AEG and autoimmune diseases are more likely in EGJOO than in AC. A considerable part of EGJOO may be the early manifestation of an organic disease. Anatomical EGJOO patients experience symptom improvement with the resolution of primary diseases, while most functional EGJOO patients experience symptom relief with pharmacotherapy alone or even without any treatment.

Abstract
INTRODUCTION Esophagogastric junction (EGJ) outflow obstruction (EGJOO) per Chicago Classification v4.0 (CCv4.0) represents a high-resolution manometry (HRM) diagnosis with uncertain clinical significance. This study aimed to evaluate functional lumen imaging probe (FLIP) panometry among patients with EGJOO on HRM/CCv4.0 to assess clinical/manometric associations and treatment outcomes. METHODS An observational cohort study was performed on patients who completed FLIP during endoscopy and had an HRM/CCv4.0 diagnosis of EGJOO, i.e., HRM-EGJOO (inconclusive). Abnormal FLIP panometry motility classifications were applied to identify FLIP-confirmed conclusive EGJOO. Rapid drink challenge on HRM and timed barium esophagram were also assessed. Clinical management plan was determined by treating physicians and assessed through chart review. Clinical outcome was defined using the Eckardt score (ES) during follow-up evaluation: ES < 3 was considered a good outcome. RESULTS Of 139 adult patients with manometric EGJOO (inconclusive per CCv4.0), a treatment outcome ES was obtained in 55 after achalasia-type treatment (i.e., pneumatic dilation, peroral endoscopic myotomy, laparoscopic Heller myotomy, or botulinum toxin injection) and 36 patients after other nonachalasia-type treatment. Among patients with conclusive EGJOO by HRM-FLIP complementary impression, 77% (33/43) had a good outcome after achalasia-type treatment, whereas 0% (0/12) of patients had a good outcome after nonachalasia-type treatment. Of patients with normal EGJ opening on FLIP, one-third of patients treated with achalasia-type treatment had a good outcome, while 9 of the 10 treated conservatively had a good outcome. DISCUSSION FLIP panometry provides a useful complement to clarify the clinical significance of an HRM/CCv4.0 EGJOO diagnosis and help direct management decisions.

Abnormal response after multiple rapid swallow provocation is not predictive of post-operative dysphagia following a tailored fundoplication approach. Surg Endosc 2022; 37:3982-3993. [PMID: 36068387 DOI: 10.1007/s00464-022-09507-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Accepted: 07/23/2022] [Indexed: 11/24/2022]
Abstract
INTRODUCTION The aim was to evaluate the clinical significance of multiple rapid swallows (MRS) during high-resolution manometry (HRM) prior to fundoplication. Despite pre-operative HRM, up to 38% of patients report post-fundoplication dysphagia. Suggestion that MRS improves prediction of dysphagia after fundoplication has not been investigated when using a tailored approach. We hypothesize response to MRS is predictive of dysphagia after tailored fundoplication. METHODS A retrospective cohort study was performed on patients undergoing HRM with MRS provocation 5/2019-7/2021 at a single institution. Patients who underwent subsequent index laparoscopic fundoplication, without peptic stricture or achalasia, were included. After performing standard 10-swallow HRM, MRS provocation was performed. Patient-reported dysphagia frequency scores were collected at initial consultation and post-operative follow-up. At least weekly symptoms were considered clinically significant. Normal MRS response was defined as adequate deglutitive inhibition and MRS contractile response. Fundoplications were tailored based on standard HRM values. RESULTS HRM was performed in 1201 patients, 220 met inclusion criteria. Clinically significant pre-operative dysphagia was reported by 85 (38.6%). Patients undergoing partial fundoplication (n = 123, 55.9%) had lower mean distal contractile integer, distal esophageal contraction amplitude, and percent peristalsis (p < 0.005). Post-operatively, 120 (54.5%) were without dysphagia, 59 (26.8%) had improved dysphagia, 26 (11.8%) had unchanged dysphagia, and 15 (6.8%) reported new dysphagia. There was no statistical difference in early or late dysphagia outcome between tailored fundoplication groups (p = 0.69). On univariate and multivariate analysis, neither MRS response, nor standard HRM metrics were significantly associated with post-operative dysphagia. Younger age (OR 0.96, 95% CI 0.94-0.986, p = 0.042) and the presence of pre-operative dysphagia (OR 2.54, 95% CI 1.17-5.65, p = 0.015) were significant predictors of post-operative dysphagia. CONCLUSION The risk of clinically significant dysphagia post-fundoplication is low when using a tailored approach based on standard HRM metrics. Additional data provided by MRS does not add to surgical decision-making using the investigated approach.

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
Among recent advances in diagnostics for dysphagia and esophageal motility disorders is the update to the Chicago Classification (version 4.0) for interpretation of high-resolution manometry (HRM) and diagnosis of esophageal motility disorders. The update incorporates application of complementary testing strategies during HRM, such as provocative HRM maneuvers, and recommendation for barium esophagram or functional luminal imaging probe (FLIP) panometry to help clarify inconclusive HRM findings. FLIP panometry also represents an emerging technology for evaluation of esophageal distensibility and motility at the time of endoscopy.

Abstract
BACKGROUND Functional luminal imaging probe (FLIP) Panometry assesses the esophageal response to distention and may complement the assessment of primary peristalsis on high-resolution manometry (HRM). We aimed to investigate whether FLIP Panometry provides complementary information in patients with normal esophageal motility on HRM. METHODS Adult patients that completed FLIP and had an HRM classification of normal motility were retrospectively identified for inclusion. 16-cm FLIP studies performed during endoscopy were evaluated to assess EGJ distensibility, secondary peristalsis, and identify an abnormal response to distention involving sustained LES contraction (sLESC). Clinical characteristics and esophagram were assessed when available. KEY RESULTS Of 164 patients included (mean(SD) age 48(16) years, 75% female), 111 (68%) had normal Panometry with EGJ-distensibility index (DI) ≥2.0 mm2 /mmHg, maximum EGJ diameter ≥16mm and antegrade contractions. Abnormal EGJ distensibility was observed in 44/164 (27%), and 38/164 (23%) had an abnormal contractile response to distension. sLESC was observed in 11/164 (7%). Among 68 patients that completed esophagram, abnormal EGJ distensibility was more frequently observed with an abnormal esophagram than normal EGJ opening: 14/23 (61%) vs 10/45 (22%); P=0.003. Epiphrenic diverticula were present in 3/164 patients: 2/3 had sLESC. CONCLUSIONS & INFERENCES Symptomatic patients with normal esophageal motility on HRM predominantly have normal FLIP Panometry; however, abnormal FLIP findings can be observed. While abnormal Panometry findings appear clinically relevant via an association with abnormal bolus retention, complementary tests, such as provocative maneuvers with HRM and timed barium esophagram, are useful to determine clinical context.

Abstract
The Chicago Classification v4.0 (CCv4.0) is the updated classification scheme for esophageal motility disorders using metrics from high-resolution manometry (HRM). A key feature of CCv.4.0 is the more rigorous and expansive protocol that incorporates single wet swallows acquired in different positions (supine, upright) and provocative testing, including multiple rapid swallows and rapid drink challenge. Additionally, solid bolus swallows, solid test meal, and/or pharmacologic provocation can be used to identify clinically relevant motility disorders and other conditions (eg, rumination) that occur during and after meals. The acquisition and analysis for performing these tests and the evidence supporting their inclusion in the Chicago Classification protocol is detailed in this technical review. Provocative tests are designed to increase the diagnostic sensitivity and specificity of HRM studies for disorders of esophageal motility. These changes attempt to minimize ambiguity in prior iterations of Chicago Classification, decrease the proportion of HRM studies that deliver inconclusive diagnoses and increase the number of patients with a clinically relevant diagnosis that can direct effective therapy. Another aim in establishing a standard manometry protocol for motility laboratories around the world is to facilitate procedural consistency, improve diagnostic reliability, and promote collaborative research.

Abstract
Esophageal motility disorders were re-defined when high-resolution manometry was employed to better understand their pathogenesis. Newly developed parameters including integrated relaxation pressure (IRP), distal contractile integral, and distal latency showed better diagnostic yield compared with previously used conventional parameters. Therefore, Chicago classification was formulated, and its diagnostic cascade begins by assessing the IRP value. However, IRP showed limitation due to its inconsistency, and other studies have tried to overcome this. Recent studies showed that provocative tests, supplementing the conventional esophageal manometry protocol, have improved the diagnostic yield of the esophageal motility disorders. Therefore, position change from supine to upright, solid or semi-solid swallowing, multiple rapid swallows, and the rapid drink challenge were newly added to the manometry protocol in the revised Chicago classification version 4.0. Impedance planimetry enables measurement of bag cross-sectional area at various locations. The functional lumen imaging probe (FLIP) has been applied to assess luminal distensibility. This probe can also measure pressure, serial cross-sectional areas, and tension-strain relationship. The esophagogastric junction's distensibility is decreased in achalasia. Therefore, EndoFLIP can be used to assess contractility and distensibility of the esophagus in the patients with achalasia, including repetitive antegrade or retrograde contractions. EndoFLIP can detect achalasia patients with relatively low IRP, which was difficult to diagnose using the current high-resolution manometry. EndoFLIP also provides information on the contractile activity and distensibility of the esophageal body in patients with achalasia. The use of provocative tests, newly added in Chicago classification 4.0 version, and EndoFLIP can expand understanding of esophageal motility disorders.

Abstract
Chicago Classification v4.0 (CCv4.0) is the updated classification scheme for esophageal motility disorders using metrics from high-resolution manometry (HRM). Fifty-two diverse international experts separated into seven working subgroups utilized formal validated methodologies over two-years to develop CCv4.0. Key updates in CCv.4.0 consist of a more rigorous and expansive HRM protocol that incorporates supine and upright test positions as well as provocative testing, a refined definition of esophagogastric junction (EGJ) outflow obstruction (EGJOO), more stringent diagnostic criteria for ineffective esophageal motility and description of baseline EGJ metrics. Further, the CCv4.0 sought to define motility disorder diagnoses as conclusive and inconclusive based on associated symptoms, and findings on provocative testing as well as supportive testing with barium esophagram with tablet and/or functional lumen imaging probe. These changes attempt to minimize ambiguity in prior iterations of Chicago Classification and provide more standardized and rigorous criteria for patterns of disorders of peristalsis and obstruction at the EGJ.
