Esophageal motor disorders across ages: A retrospective multicentric analysis. J Am Geriatr Soc 2024; 72:2782-2791. [PMID: 38975863 DOI: 10.1111/jgs.19068] [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: 03/01/2024] [Revised: 06/02/2024] [Accepted: 06/11/2024] [Indexed: 07/09/2024]
Abstract
BACKGROUND Age-related changes in the gastrointestinal system are common and may be influenced by physiological aging processes. To date, a comprehensive analysis of esophageal motor disorders in patients belonging to various age groups has not been adequately reported. METHODS We conducted a retrospective assessment of high-resolution manometry (HRM) studies in a multicenter setting. HRM parameters were evaluated according to the Chicago Classification version 4.0. Epidemiological, demographic, clinical data, and main manometric parameters, were collected at the time of the examination. Age groups were categorized as early adulthood (<35 years), early middle-age (35-49 years), late middle-age (50-64 years), and late adulthood (≥65 years). RESULTS Overall, 1341 patients (632, 47.0% male) were included with a median age of 55 years. Late adulthood patients reported more frequently dysphagia (35.2%) than early adulthood patients (24.0%, p = 0.035), early middle-age patients (21.0%, p < 0.0001), and late middle-aged patients (22.7%, p < 0.0001). Esophagogastric junction outflow obstruction was more prevalent in late adulthood (16.7%) than in early adulthood (6.1%, p = 0.003), and in early middle-age (8.1%, p = 0.001). Patients with normal esophageal motility were significantly younger (52.0 years) than patients with hypercontractile esophagus (61.5 years), type III achalasia (59.6 years), esophagogastric junction outflow obstruction (59.4 years), absent contractility (57.2 years), and distal esophageal spasm (57.0 years), in multivariate model (p < 0.0001). CONCLUSION The rate of esophageal motor disorders is higher in older patients, in particular esophagogastric junction outflow obstruction and hypercontractile esophagus. Future prospective studies are necessary to confirm our results and to find tailored strategies to improve clinical outcomes.

Alterations in gastrointestinal motility assessed by high-resolution antroduodenal manometry in patients with severe disorders of gut-brain interaction. Am J Physiol Gastrointest Liver Physiol 2024; 327:G306-G315. [PMID: 38860287 DOI: 10.1152/ajpgi.00039.2024] [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: 02/05/2024] [Revised: 05/28/2024] [Accepted: 06/07/2024] [Indexed: 06/12/2024]
Abstract
Data are limited regarding gastrointestinal motility disturbance in disorders of gut-brain interaction (DGBI). This study aimed to characterize antroduodenal motor alterations in patients with high-resolution antroduodenal manometry (HR-ADM). HR-ADM was performed in patients with severe DGBI and compared with healthy volunteers (HV). HR-ADM used a commercially available probe composed of 36 electronic sensors spaced 1 cm apart and positioned across the pylorus. Antral and duodenal motor high-resolution profiles were analyzed, based on the frequency, amplitude, and contractile integral/sensor (CI/s) calculated for each phase of the migrating motor complex (MMC). Eighteen HV and 64 patients were investigated, 10 with irritable bowel syndrome (IBS), 24 with functional dyspepsia (FD), 15 with overlap IBS-FD, and 15 with other DGBI. Compared with HV, patients had a lower frequency of phase II duodenal contractions (27 vs. 51 per hour; P = 0.002) and a lower duodenal phase II contraction amplitude (70 vs. 100 mmHg; P = 0.01), resulting in a lower CI/s of phase II (833 vs. 1,901 mmHg·cm·s; P < 0.001) in the duodenum. In addition, the frequency of phase II propagated antroduodenal contractions was lower (5 vs. 11 per hour; P < 0.001) in patients compared with HV. Interestingly, the antral CI/s of phase III was decreased in FD patients but not in IBS patients. Patients with severe DGBI display alterations in antral and intestinal motility assessed by commercially available HR-ADM. Whether these alterations may explain symptom profiles in such patients remains to be confirmed (NCT04918329 and NCT01519180).NEW & NOTEWORTHY Gastrointestinal dysmotility has been assessed poorly in disorders of gut-brain interaction (DGBI), especially with high-resolution antroduodenal manometry. Plots of DGBI patients showed lower duodenal contractions during phase II regarding amplitude, frequency, and contractile integral/sensor (CI/s) compared with healthy volunteers. A lower frequency of propagated antroduodenal contractions was also reported. Finally, antral CI/s was lower in patients with functional dyspepsia during phase III. Further studies are needed to assess the clinical significance of these alterations.

Esophagogastroduodenoscopy findings that do no not explain dysphagia are associated with underutilization of high-resolution manometry. Dis Esophagus 2024; 37:doae028. [PMID: 38582609 DOI: 10.1093/dote/doae028] [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: 04/24/2023] [Revised: 03/15/2024] [Accepted: 03/17/2024] [Indexed: 04/08/2024]
Abstract
In patients with dysphagia that is not explained by upper endoscopy, high-resolution esophageal manometry (HRM) is the next logical step in diagnostic testing. This study investigated predictors of failure to refer for HRM after an upper endoscopy that was performed for but did not explain dysphagia. This was a retrospective cohort study of patients >18 years of age who underwent esophagogastroduodenoscopy (EGD) for dysphagia from 2015 to 2021. Patients with EGD findings that explained dysphagia (e.g. esophageal mass, eosinophilic esophagitis, Schatzki ring, etc.) were excluded from the main analyses. The primary outcome was failure to refer for HRM within 1 year of the index non-diagnostic EGD. We also investigated delayed referral for HRM, defined as HRM performed after the median. Multivariable logistic regression modeling was used to identify risk factors that independently predicted failure to refer for HRM, conditioned on the providing endoscopist. Among 2132 patients who underwent EGD for dysphagia, 1240 (58.2%) did not have findings to explain dysphagia on the index EGD. Of these 1240 patients, 148 (11.9%) underwent HRM within 1 year of index EGD. Endoscopic findings (e.g. hiatal hernia, tortuous esophagus, Barrett's esophagus, surgically altered anatomy not involving the gastroesophageal junction, and esophageal varices) perceived to explain dysphagia were independently associated with failure to refer for HRM (adjusted odds ratio 0.45, 95% confidence interval 0.25-0.80). Of the 148 patients who underwent HRM within 1 year of index EGD, 29.7% were diagnosed with a disorder of esophagogastric junction outflow, 17.6% with a disorder of peristalsis, and 2.0% with both disorders of esophagogastric outflow and peristalsis. The diagnosis made by HRM was similar among those who had incidental EGD findings that were non-diagnostic for dysphagia compared with those who had completely normal EGD findings. Demographic factors including race/ethnicity, insurance type, and income were not associated with failure to refer for HRM or delayed HRM. Patients with dysphagia and endoscopic findings unrelated to dysphagia have a similar prevalence of esophageal motility disorders to those with normal endoscopic examinations, yet these patients are less likely to undergo HRM. Provider education is indicated to increase HRM referral in these patients.

Abstract
Evaluating clinical care through quality-related metrics is increasingly common. There are now numerous quality statements and indicators related to the medical management of benign and pre-malignant esophageal diseases. Expert consensus leveraging evidence-based recommendations from published society guidelines has been the most frequently used basis for developing esophageal quality statements. While surgical care of patients with esophageal malignancies, including squamous cell carcinoma, has also been developed, those related to benign esophageal disease now include domains of diagnosis, treatment, and monitoring for gastroesophageal reflux disease, eosinophilic esophagitis (EoE), achalasia, and Barrett's esophagus (BE). Several recent studies evaluating adherence to quality metrics affirm substantial variation in practice patterns with opportunities for improvement in care across esophageal diseases. In particular, patient education regarding treatment options in achalasia, frequency of esophageal biopsies among patients with dysphagia to evaluate for EoE, and endoscopic evaluation within a BE segment are areas identified to have need for improvement. As the management of esophageal diseases becomes more complex and interdisciplinary, adherence to quality metrics may be a source of standardization and improvement in delivery and ultimately patient outcomes. Indeed, the development of national quality databases has resulted in a significant growth in the use of these metrics for quality improvement activities and may form the basis for future inclusion in quality reporting and payment programs.

Abstract
INTRODUCTION Guidelines advise esophageal motility testing for dysphagia when structural disorders are ruled out, but cost concerns impede adoption. We evaluated cost-effective positioning of esophageal motility testing in the algorithm to evaluate esophageal dysphagia. METHODS We developed a decision analytic model comparing 3 strategies: (i) esophageal manometry, (ii) screening impedance planimetry followed by esophageal manometry if needed, or (iii) nonalgorithmic usual care. Diagnostic test accuracy was adapted to expected rates of esophageal motility disorders in general gastroenterology populations. We modeled routine testing for all patients with nonstructural/mechanical dysphagia compared with selective testing with strong suspicion for achalasia. Cost outcomes were defined on national commercial and Medicare datasets stratified on age and sex. Health outcomes were modeled on populations with achalasia. The time horizon was 1 year. RESULTS Motility testing was preferred over nonalgorithmic usual care due to cost savings rather than health gains. To commercial insurers, routine esophageal manometry for nonstructural/mechanical dysphagia would be cost-saving below a reimbursed cost of $2,415. Screening impedance planimetry would be cost saving below a reimbursed cost of $1,130. The limit for reimbursed costs would be lower for patients older than 65 years to achieve cost savings mainly due to insurance. Sex did not significantly influence cost-effectiveness. Patients and insurers preferred routine screening impedance planimetry before manometry when the index of suspicion for achalasia was below 6%. DISCUSSION Aligning with practice guidelines, routine esophageal motility testing seems cost saving to patients and insurers compared with nonalgorithmic usual care to evaluate nonstructural/mechanical dysphagia. Choice of testing should be guided by index of suspicion.

Abstract
INTRODUCTION Gastroesophageal reflux disease (GERD) is very prevalent in the general population, with a broad spectrum of clinical manifestations, requiring accurate diagnosis and treatment. AIM The aim of this expert review is to establish good clinical practice recommendations for the diagnosis and personalized treatment of GERD. METHODS The good clinical practice recommendations were produced by a group of experts in GERD, members of the Asociación Mexicana de Gastroenterología (AMG), after carrying out an extensive review of the published literature and discussing each recommendation at a face-to-face meeting. This document does not aim to be a clinical practice guideline with the methodology such a document requires. RESULTS Fifteen experts on GERD formulated 27 good clinical practice recommendations for recognizing the symptoms and complications of GERD, the rational use of diagnostic tests and medical treatment, the identification and management of refractory GERD, the overlap with functional disorders, endoscopic and surgical treatment, and GERD in the pregnant woman, older adult, and the obese patient. CONCLUSIONS An accurate diagnosis of GERD is currently possible, enabling the prescription of a personalized treatment in patients with this condition. The goal of the good clinical practice recommendations by the group of experts from the AMG presented in this document is to aid both the general practitioner and specialist in the process of accurate diagnosis and treatment, in the patient with GERD.

Abstract
Background/Aims Although an association between achalasia and esophageal cancer has been reported, whether achalasia confers a substantial increase in mortality is unknown. Moreover, the causes of death related to achalasia have not been investigated. We performed this nationwide, population-based cohort study on achalasia because no such study has been performed since the introduction of high-resolution manometry in 2008. Methods This study was performed using data extracted from the Korean National Health Insurance Service database, covering a 9-year period from 2009 to 2017. Control participants without a diagnostic code for achalasia were randomly selected and matched by sex and birth year at a case-to-control ratio of 1:4. Data on the cause of death from Statistics Korea were also analyzed. Results The overall incidence of achalasia was 0.68 per 100,000 person-years, and the prevalence was 6.46 per 100,000 population. Patients with achalasia (n=3,063) had significantly higher adjusted hazard ratio (aHR) for esophageal cancer (aHR, 3.40; 95% confidence interval [CI], 1.25 to 9.22; p=0.017), pneumonia (aHR, 2.30; 95% CI, 1.89 to 2.81; p<0.001), aspiration pneumonia (aHR, 3.92; 95% CI, 2.38 to 6.48; p<0.001), and mortality (aHR, 1.68; 95% CI, 1.44 to 1.94; p<0.001). Esophageal cancer carried the highest mortality risk (aHR, 8.82; 95% CI, 2.35 to 33.16; p=0.001), while pneumonia had the highest non-cancer mortality risk (aHR, 2.28; 95% CI, 1.31 to 3.96; p=0.004). Conclusions In this nationwide study, achalasia was associated with increased risk of mortality. Esophageal cancer and pneumonia were the most common comorbidities and the major causes of death in patients with achalasia.

Abstract
Esophageal motility disorders are diseases in which there are malfunctions of the act of swallowing due to a change in neuromuscular structures. The main symptom is therefore dysphagia for solid and/or liquid foods, often accompanied by symptoms such as chest pain, regurgitation, heartburn, and weight loss. Esophageal manometry is the gold standard in diagnostics. Endoscopy and radiology serve to exclude inflammatory or malignant changes. With the introduction of high-resolution esophageal manometry (HRM), the diagnosis of esophageal motility disorders has improved and led to a new classification with the Chicago Classification, which has been modified several times in the last decade, most recently in 2021 with the Chicago Classification v4.0. Compared to the previous version 3.0, there are some important changes that are presented based on the most important esophageal motility disorders in everyday clinical practice.

Interrater Reliability of Functional Lumen Imaging Probe Panometry and High-Resolution Manometry for the Assessment of Esophageal Motility Disorders. Am J Gastroenterol 2023; 118:1334-1343.

Abstract
INTRODUCTION High-resolution manometry (HRM) and functional lumen imaging probe (FLIP) are primary and/or complementary diagnostic tools for the evaluation of esophageal motility. We aimed to assess the interrater agreement and accuracy of HRM and FLIP interpretations. METHODS Esophageal motility specialists from multiple institutions completed the interpretation of 40 consecutive HRM and 40 FLIP studies. Interrater agreement was assessed using intraclass correlation coefficient (ICC) for continuous variables and Fleiss' κ statistics for nominal variables. Accuracies of rater interpretation were assessed using the consensus of 3 experienced raters as the reference standard. RESULTS Fifteen raters completed the HRM and FLIP studies. An excellent interrater agreement was seen in supine median integral relaxation pressure (ICC 0.96, 95% confidence interval 0.95-0.98), and a good agreement was seen with the assessment of esophagogastric junction (EGJ) outflow, peristalsis, and assignment of a Chicago Classification version 4.0 diagnosis using HRM (κ = 0.71, 0.75, and 0.70, respectively). An excellent interrater agreement for EGJ distensibility index and maximum diameter (0.91 [0.90-0.94], 0.92 [0.89-0.95]) was seen, and a moderate-to-good agreement was seen in the assignment of EGJ opening classification, contractile response pattern, and motility classification (κ = 0.68, 0.56, and 0.59, respectively) on FLIP. Rater accuracy for Chicago Classification version 4.0 diagnosis on HRM was 82% (95% confidence interval 78%-84%) and for motility diagnosis on FLIP Panometry was 78% (95% confidence interval 72%-81%). DISCUSSION Our study demonstrates high levels of interrater agreement and accuracy in the interpretation of HRM and FLIP metrics and moderate-to-high levels for motility classification in FLIP, supporting the use of these approaches for primary or complementary evaluation of esophageal motility disorders.

Abstract
Electrokinesiographic study of swallowing (EKSS) can be useful for the assessment of patients with suspected or overt neurogenic dysphagia. EKSS consists of multichannel recording of the electromyographic (EMG) activity of the suprahyoid/submental muscle complex (SHEMG), the EMG activity of the cricopharyngeal muscle (CPEMG), and the laryngopharyngeal mechanogram (LPM). The LPM is an expression of the mechanical changes that the laryngopharyngeal structures undergo during the pharyngeal phase of swallowing. This method allows detailed evaluation of the magnitude, duration and temporal relations of the different events that characterize oropharyngeal swallowing, and thus in-depth exploration both of physiological deglutition mechanisms and of pathophysiological features of swallowing in neurogenic dysphagia. Furthermore, EKSS can guide dysphagia treatment strategies, allowing identification of optimal solutions for single patients. For instance, CPEMG recording can identify incomplete or absent relaxation of the upper esophageal sphincter during the pharyngeal phase of swallowing, thus suggesting a therapeutic approach based on botulinum toxin injection into the cricopharyngeal muscle. More recently, the 'shape' of SHEMG and the reproducibility of both SHEMG and LPM over repeated swallowing acts have been implemented as novel electrokinesiographic parameters. These measures could be valuable for straightforward non-invasive investigation of dysphagia severity and response to dysphagia treatment in clinical practice.

Abstract
High-resolution esophageal manometry (HRM) utilizes sufficient pressure sensors such that intraluminal pressure is monitored as a continuum along luminal length, similar to time viewed as a continuum on polygraph tracings in 'conventional' manometry. When HRM is coupled with pressure topography plotting, and pressure amplitude is transformed into spectral colors with isobaric areas indicated by same-colored regions, "Clouse plots" are generated. HRM has several advantages compared to the technology that it replaced: (1) the contractility of the entire esophagus can be viewed simultaneously in a uniform standardized format, (2) standardized objective metrics of peristaltic and sphincter function can be systematically applied for interpretation, and (3) topographic patterns of contractility are more easily recognized with greater reproducibility. Leveraging these advantages led to the current standard for the interpretation of clinical esophageal HRM studies, the Chicago Classification (CC), now in its fourth iteration. Compared to conventional manometry, HRM has vastly improved the sensitivity for detecting achalasia, largely due to the objectivity and accuracy of identification of impaired esophagogastric junction (EGJ) relaxation. Additionally, it has led to the subcategorization of achalasia into three clinically relevant subtypes, differentiated by the contractile function of the esophageal body, and identified an additional disorder of EGJ outflow obstruction wherein esophageal peristalsis is preserved. Headway has also been made in understanding hypocontractile and hypercontractile conditions. In summary, HRM and the CC process have revolutionized our understanding of esophageal motility and motility disorders. Moving forward, there will always be remaining challenges, but we now have the tools to meet them.

Abstract
Esophageal motility disorders are diseases in which there are malfunctions of the act of swallowing due to a change in neuromuscular structures. The main symptom is therefore dysphagia for solid and/or liquid foods, often accompanied by symptoms such as chest pain, regurgitation, heartburn, and weight loss. Esophageal manometry is the gold standard in diagnostics. Endoscopy and radiology serve to exclude inflammatory or malignant changes. With the introduction of high-resolution esophageal manometry (HRM), the diagnosis of esophageal motility disorders has improved and led to a new classification with the Chicago Classification, which has been modified several times in the last decade, most recently in 2021 with the Chicago Classification v4.0. Compared to the previous version 3.0, there are some important changes that are presented based on the most important esophageal motility disorders in everyday clinical practice.

Abstract
Achalasia, characterised by the absence of peristalsis and failure of relaxation of the lower oesophageal sphincter, is an uncommon degenerative condition that results in dysphagia. If left untreated it can lead to aspiration, oesophageal perforation, oesophagitis and malnutrition. It has a range of immune, allergic, viral and genetic aetiological causes. Successful diagnosis relies on the use of oesophagogastroduodenoscopy, barium swallow and oesophageal manometry to characterise the severity of the disease and to rule out underlying malignancy. Although no treatment can reverse the degenerative process, therapeutic strategies including lifestyle modification, medication, endoscopic and operative intervention can help to reduce symptoms. This article reviews the latest methods used to investigate and manage achalasia.

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
Achalasia is a rare disorder of the oesophageal smooth muscle characterized by impaired relaxation of the lower oesophageal sphincter (LES) and absent or spastic contractions in the oesophageal body. The key pathophysiological mechanism is loss of inhibitory nerve function that probably results from an autoimmune attack targeting oesophageal myenteric nerves through cell-mediated and, possibly, antibody-mediated mechanisms. Achalasia incidence and prevalence increase with age, but the disorder can affect all ages and both sexes. Cardinal symptoms consist of dysphagia, regurgitation, chest pain and weight loss. Several years can pass between symptom onset and an achalasia diagnosis. Evaluation starts with endoscopy to rule out structural causes, followed by high-resolution manometry and/or barium radiography. Functional lumen imaging probe can provide complementary evidence. Achalasia subtypes have management and prognostic implications. Although symptom questionnaires are not useful for diagnosis, the Eckardt score is a simple symptom scoring scale that helps to quantify symptom response to therapy. Oral pharmacotherapy is not particularly effective. Botulinum toxin injection into the LES can temporize symptoms and function as a bridge to definitive therapy. Pneumatic dilation, per-oral endoscopic myotomy and laparoscopic Heller myotomy can provide durable symptom benefit. End-stage achalasia with a dilated, non-functioning oesophagus may require oesophagectomy or enteral feeding into the stomach. Long-term complications can, rarely, include oesophageal cancer, but surveillance recommendations have not been established.

Abstract
Little attention has been given to esophageal disorders in diabetes mellitus. Pathophysiology of esophageal motility disorders (EMD) in patients with diabetes mellitus is multifactorial. The aims of the present study were: (a) to evaluate the prevalence of EMD in patients with Type 2 diabetes mellitus and (b) to determine the relationship between EMD and autonomic neuropathy as assessed by heart rate variability (HRV). All the patients completed a questionnaire about diabetes characteristics and gastrointestinal symptoms. Conventional esophageal manometry was performed in all patients. HRV was measured in three different situations (Lying Position 1, standing position, and Lying Position 2). The temporal and frequency domain parameters were considered for analysis. The prevalence of EMD in our patients was 60.5% (n = 23). Low score physical activity was significantly more frequent in patients with EMD (p = .03). There was an increase in sympathetic activity represented by the low frequency (LF) parameter (p = .027) in the presence of EMD. Whereas parasympathetic modulation of heart rate represented by the high frequency (HF) parameter (p = .027) was declined in patients with EMD compared to those without. The LF/HF ratio was significantly higher (p = .002) in patients with EMD. EMD were prevalent in diabetes mellitus and were associated to autonomic nervous system dysfunction predominantly at the parasympathetic component.

Abstract
Gastroesophageal reflux disease (GERD) is one of the most prevalent and bothersome functional gastrointestinal disorders worldwide, including in Thailand. After a decade of the first Thailand GERD guideline, physician and gastroenterologist encountered substantially increase of patients with GERD. Many of them are complicated case and refractory to standard treatment. Concurrently, the evolution of clinical characteristics as well as the progression of investigations and treatment have developed and changed tremendously. As a member of Association of Southeast Asian Nations, which are developing countries, we considered that the counterbalance between advancement and sufficient economy is essential in taking care of patients with GERD. We gather physicians from university hospitals, as well as internist and general practitioners who served in rural area, to make a consensus in this updated version of GERD guideline focusing in medical management of GERD. This clinical practice guideline was constructed adhering with standard procedure. We categorized the guideline in to four parts including definition, investigation, treatment, and long-term follow up. We anticipate that this guideline would improve physicians' proficiency and help direct readers to choose investigations and treatments in patients with GERD wisely. Moreover, we wish that this guideline would be applicable in countries with limited resources as well.

Elevated average maximum intrabolus pressure on high-resolution manometry is associated with esophageal dysmotility and delayed esophageal emptying on timed barium esophagram. BMC Gastroenterol 2022; 22:74. [PMID: 35189822 PMCID: PMC8859877 DOI: 10.1186/s12876-022-02165-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Accepted: 02/04/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Intrabolus pressure (IBP) recorded by high-resolution manometry (HRM) portrays the compartmentalized force on a bolus during esophageal peristalsis. HRM may be a reliable screening tool for esophageal dysmotility in patients with elevated average maximum IBP (AM-IBP). Timed barium esophagram (TBE) is a validated measure of esophageal emptying disorders, such as esophagogastric junction outflow obstruction and achalasia. This study aimed to determine if an elevated AM-IBP correlates with esophageal dysmotility on HRM and/or delayed esophageal emptying on TBE. METHODS A retrospective analysis of all HRM (unweighted sample n = 155) performed at a tertiary referral center from 09/2015-03/2017 yielded a case group (n = 114) with abnormal AM-IBP and a control group (n = 41) with a normal AM-IBP (pressure < 17 mmHg) as consistent with Chicago Classification 3. All patients received a standardized TBE, with abnormalities classified as greater than 1 cm of retained residual liquid barium in the esophagus at 1 and 5 min or as tablet retention after 5 min. RESULTS AM-IBP was significantly related to liquid barium retention (p = 0.003) and tablet arrest on timed barium esophagram (p = 0.011). A logistic regression model correctly predicted tablet arrest in 63% of cases. Tablet arrest on AM-IBP correlated with an optimal prediction point at 20.1 mmHg on HRM. Patients with elevated AM-IBP were more likely to have underlying esophageal dysmotility (95.6% vs. 70.7% respectively; p < 0.001), particularly esophagogastric junction outflow obstruction disorders. Elevated AM-IBP was associated with incomplete liquid bolus transit on impedance analysis (p = 0.002). CONCLUSIONS Our findings demonstrate that an elevated AM-IBP is associated with abnormal TBE findings of esophageal tablet retention and/or bolus stasis. An abnormal AM-IBP (greater than 20.1 mm Hg) was associated with a higher probability of retaining liquid bolus or barium tablet arrest on TBE and esophageal dysmotility on HRM. This finding supports the recent incorporation of IBP in Chicago Classification v4.0.

[PMID: 35115131 PMCID: PMC8817064 DOI: 10.1016/j.artmed.2021.102233] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2021] [Revised: 12/17/2021] [Accepted: 12/18/2021] [Indexed: 02/03/2023]
Abstract
High-resolution manometry (HRM) is the primary procedure used to diagnose esophageal motility disorders. Its manual interpretation and classification, including evaluation of swallow-level outcomes and then derivation of a study-level diagnosis based on Chicago Classification (CC), may be limited by inter-rater variability and inaccuracy of an individual interpreter. We hypothesized that an automatic diagnosis platform using machine learning and artificial intelligence approaches could be developed to accurately identify esophageal motility diagnoses. Further, a multi-stage modeling framework, akin to the step-wise approach of the CC, was utilized to leverage advantages of a combination of machine learning approaches including deep-learning models and feature-based models. Models were trained and tested using a dataset comprised of 1741 patients' HRM studies with CC diagnoses assigned by expert physician raters. In the swallow-level stage, three models based on convolutional neural networks (CNNs) were developed to predict swallow type and swallow pressurization (test accuracies of 0.88 and 0.93, respectively), and integrated relaxation pressure (IRP)(regression model with test error of 4.49 mmHg). At the study-level stage, model selection from families of the expert-knowledge-based rule models, xgboost models and artificial neural network(ANN) models were conducted. A simple model-agnostic strategy of model balancing motivated by Bayesian principles was utilized, which gave rise to model averaging weighted by precision scores. The averaged (blended) models and individual models were compared and evaluated, of which the best performance on test dataset is 0.81 in top-1 prediction, 0.92 in top-2 predictions. This is the first artificial-intelligence style model to automatically predict esophageal motility (CC) diagnoses from HRM studies using raw multi-swallow data and it achieved high accuracy. Thus, this proposed modeling framework could be broadly applied to assist with HRM interpretation in a clinical setting.

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
Achalasia is a rare chronic esophageal motility disorder characterized by incomplete relaxation of the lower esophageal sphincter and abnormal peristalsis. This abnormal motor function leads to impaired bolus emptying and symptoms of dysphagia, regurgitation, chest pain, or heartburn. After an upper endoscopy to exclude structural causes of symptoms, the gold standard for diagnosis is high-resolution esophageal manometry. However, complementary diagnostic tools include barium esophagram and functional luminal impedance planimetry. Definitive treatments include pneumatic dilation, Heller myotomy with fundoplication, and peroral endoscopic myotomy.

Clinical usefulness of esophageal high resolution manometry and adjunctive tests: An update. Dig Liver Dis 2021; 53:1373-1380.

Abstract
High resolution manometry (HRM), developed from conventional manometry, is the gold standard for assessment of esophageal motor function worldwide. The Chicago Classification, now in its fourth iteration, is the modern standard for HRM categorization of esophageal motility disorders. The HRM protocol has expanded from the original 10 supine swallow standard, to include upright swallows, and provocative maneuvers such as multiple rapid swallows, rapid drink challenge and standardized test meal. Impedance has been incorporated into HRM for visualization of bolus clearance. Futhermore, barium radiography and functional lumen imaging probe complement HRM when evidence of esophagogastric junction obstruction is inconclusive. The biggest impact of HRM is in the improved diagnosis and subtyping of achalasia spectrum disorders, with implications on management. Spastic disorders and absent contractility are better characterized. Within the reflux spectrum, HRM provides definition of morphology and tone of the esophagogastric junction, and assesses integrity of esophageal body peristalsis, which have pathophysiologic implications for reflux and its clearance. HRM provides characterization of behavioral disorders such as supragastric belching and rumination syndrome, which can mimic reflux disease. Thus, HRM has revolutionized the evaluation of esophageal motor function, and has expanded the utility of esophageal manometry in clinical practice.

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
BACKGROUND The management of achalasia has improved due to diagnostic and therapeutic innovations. However, variability in care delivery remains and no established measures defining quality of care for this population exist. We aimed to use formal methodology to establish quality indicators for achalasia patients. METHODS Quality indicator concepts were identified from the literature, consensus guidelines and clinical experts. Using RAND/University of California, Los Angeles (UCLA) Appropriateness Method, experts in achalasia independently ranked proposed concepts in a two-round modified Delphi process based on 1) importance, 2) scientific acceptability, 3) usability, and 4) feasibility. Highly valid measures required strict agreement (≧ 80% of panelists) in the range of 7-9 for across all four categories. KEY RESULTS There were 17 experts who rated 26 proposed quality indicator topics. In round one, 2 (8%) quality measures were rated valid. In round two, 19 measures were modified based on panel suggestions, and experts rated 10 (53%) of these measures as valid, resulting in a total of 12 quality indicators. Two measures pertained to patient education and five to diagnosis, including discussing treatment options with risk and benefits and using the most recent version of the Chicago Classification to define achalasia phenotypes, respectively. Other indicators pertained to treatment options, such as the use of botulinum toxin for those not considered surgical candidates and management of reflux following achalasia treatment. CONCLUSIONS & INFERENCES Using a robust methodology, achalasia quality indicators were identified, which can form the basis for establishing quality gaps and generating fully specified quality measures.

Abstract
BACKGROUND Three manometric subtypes of achalasia were defined in the Chicago Classification approximately 10 years ago: type I (aperistalsis), type II (pan-pressurization), and type III (spastic). Since the widespread use of this classification scheme, the evolving prevalence of these subtypes has not been elucidated. We aim to determine the prevalence of each subtype a decade after the adoption of the Chicago Classification. METHODS This is a retrospective cohort analysis of patients diagnosed with achalasia on high-resolution manometry (HRM) at two major academic medical centers between 2015 and 2018. Patients were excluded if they had a diagnosis of another esophageal motility disorder, previously treated achalasia, or foregut surgery. Demographic data, manometric subtype, and esophageal dilatation grade on endoscopy were obtained. Prevalence of achalasia subtypes was compared with a published historical control population (2004-2007). Fischer's exact and t tests were used for analysis. RESULTS Of 147 patients in the contemporary cohort and 99 in the historical control cohort, the prevalence of type I achalasia was 8% versus 21%, type II 63% versus 50%, and type III 29% versus 29%, respectively (p = 0.01). The mean age in our population was 58 years compared to 57 years in the historical control, and the proportion of men 48% versus 47%, respectively (p = 0.78). Mean endoscopic dilatation grade in the contemporary cohort was 1.5 for type I patients, 0.9 for type II, and 0.4 for type III, compared with 1.5, 0.6, and 0.4, respectively. Overall mean dilatation grade was 0.8 in our cohort versus 0.7 in the historical control (p = 0.58). CONCLUSION The prevalence of type II achalasia was significantly greater and prevalence of type I significantly less in our patient population compared to our predefined historical control. Other characteristics such as age and sex did not appear to contribute to these differences. Histopathological evidence has suggested that type II achalasia may be an earlier form of type I; thus, the increased prevalence of type II achalasia may be related to earlier detection of the disease. The adoption of HRM, widespread use of the Chicago Classification, and increased disease awareness in the past decade may be contributing to these changes in epidemiology.

Abstract
Minimally invasive surgery (MIS) has improved surgical access to the foregut. While the benefits of MIS versus open surgery are well accepted, the relative benefits of laparoscopic versus robotic approaches continue to be debated. Procedure-specific comparisons are difficult to obtain for Heller myotomy, due to the relative rarity of the procedure in most practices. A retrospective review of prospectively collected perioperative data of a single surgical practice from 2001 to 2019 was conducted for the rate of perforation during Heller myotomy laparoscopically compared to robotically. From 2001 through February 2012, a laparoscopic approach was employed and from October 2008 to 2019, a robotic approach was employed. All perforations were recorded, as well as secondary outcomes of perforation location (gastric or esophageal), postoperative imaging for evidence of leak, length of stay, and complications. Chi-square and simple t test were employed for data analysis. During the 11 years of laparoscopic Heller myotomy, 14 cases resulted in 7 instances of perforation (50%). During the 11 years of robotic Heller myotomy, 45 cases resulted in 11 instances of perforation (24%) (p value = 0.06). All perforations in both groups were tiny, recognized, and repaired immediately. The length of stay (LOS) was longer in the laparoscopic perforation group (3.4 days) compared to the laparoscopic non-perforation group (1.2 days) (p value = 0.06). LOS for robotic was not significantly longer in the perforation group (2.8 days) compared to the robotic non-perforation group (1.5 days) (p value = 0.18). First time Heller myotomies showed a higher rate of perforation with laparoscopic (50%) vs robotic (14%) (p value = 0.009) approach. In subgroup analysis of revisional procedures, all ten were performed robotically (p value < 0.001) with a 60% perforation rate (p value = 0.001) and one associated, radiographically confirmed leak. Primary laparoscopic Heller myotomy related to more than four times the frequency of perforation than did primary robotic myotomy. We propose that the robotic platform provided the surgeon with superior ability to avoid perforation. Interestingly, the robotic group in this study dealt with more complex redo cases. In fact, reoperation in the area of the hiatus was a separate risk factor for perforation during robotic Heller myotomy. We recommend further prospective trials be done to better evaluate the benefits of robotic platform in regard to revisional foregut surgery.

Abstract
AbstractAchalasia cardia is a primary motility disorder of the esophagus, defined by lack of normal esophageal peristalsis along with inadequate relaxation of lower esophageal sphincter . The mainstay of management in achalasia includes pneumatic dilatation, Heller’s myotomy and peroral endoscopic myotomy (POEM). Pneumatic dilatation and Heller’s myotomy have gained maturity over several decades. The current best practice with regard to pneumatic dilatation is graded and on-demand dilatation in appropriately selected cases with type I and II achalasia. Laparoscopic Heller’s myotomy plus partial fundoplication is minimally invasive with reduced postoperative reflux and has virtually replaced open Heller’s myotomy with or without fundoplication. The subtyping of achalasia using high-resolution manometry bears prognostic significance and may help in choosing appropriate therapeutic modality in these patients. Since all the three modalities are effective for type I and II achalasia, the choice among these depends on the availability, expertise, and patient’s preferences. On the other hand, POEM is more effective than pneumatic dilatation and Heller’s myotomy and, therefore, preferred in type III achalasia. Although POEM is effective across the spectrum of esophageal motility disorders, the incidence of gastroesophageal reflux is high and needs to be considered while choosing among various options in these patients. In cases with failed POEM, redo POEM appears to be effective in alleviating symptoms.

Abstract
Dysphagia is a common problem affecting all ages. It is increasing in frequency particularly among the younger population due to the rising incidence of eosinophilic oesophagitis, a condition which often leads to acute presentation to hospital for the first time with food bolus obstruction requiring endoscopic removal. Careful history taking remains the first and most important step in evaluating dysphagia, and it is especially important to distinguish an oropharyngeal versus oesophageal origin, which helps to guide further investigation and therapy. The three main investigations for dysphagia remain endoscopy, barium study and manometry, with endoscopy also offering therapeutic potential. Management is largely determined by the eventual diagnosis, often in a multi-disciplinary setting.

Abstract
BACKGROUND An association has been reported between achalasia and eosinophilic esophagitis (EoE). We performed a retrospective study of high-resolution manometry (HRM) patterns in a large cohort of patients with EoE. MATERIAL AND METHODS We collected data from consecutive patients with a new diagnosis of EoE from 2012 through 2019 undergoing HRM during the initial assessment at different centers in Italy. Demographic, clinical, endoscopic and histological characteristics were recorded at baseline and during management. Diagnoses of EoE and esophageal motility disorders were made according to established criteria. Treatments offered included proton pump inhibitors and topical steroids for EoE, and pneumatic dilation and myotomy for achalasia. Response to therapy was defined as less than 15 eosinophils per high power field in esophageal biopsies. RESULTS Of 109 consecutive patients (mean age 37 years, 82 male), 68 (62%) had normal findings from HRM. Among 41 patients with motor disorders, 24 (59%) had minor motor disorders and 17 (41%) presented with major motor disorders, including 8 with achalasia (1 with type 1, 4 with type 2, and 3 with type 3). Achalasia and nonachalasia obstructive motor disorders had 14.7% prevalence among patients with EoE. Achalasia was more frequent in women, with longer diagnostic delay and abnormal esophagogram (P < .05) compared with EoE without achalasia or obstructive motor disorders. Clinical features and endoscopic findings did not differ significantly between patients with EoE with vs without achalasia and obstructive motor disorders. A higher proportion of patients without achalasia and obstructive motor disorders responded to topical steroids than patients with these features (P < .005). Invasive achalasia management was required for symptom relief in 50% of patients with achalasia and obstructive motor disorders. CONCLUSION Achalasia and obstructive motor disorders are found in almost 15% of patients with EoE, and esophageal eosinophilia might cause these disorders. Patients with EoE who do not respond to standard treatments might require targeted muscle disruption.

Utility of a new automated diagnostic program in high-resolution esophageal manometry. J Gastroenterol 2021; 56:633-639. [PMID: 33987747 DOI: 10.1007/s00535-021-01794-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Accepted: 05/04/2021] [Indexed: 02/04/2023]
Abstract
BACKGROUND A new automated diagnostic program for high-resolution esophageal manometry (HREM) has been developed. This diagnostic program could detect locations of landmarks and could make final diagnoses automatically. However, the accuracy of the program is not known. The aim of this study was to evaluate the accuracy of the automated diagnostic program for HREM. METHODS A total of 445 studies were enrolled. An HREM system (Starlet®) was used, and esophageal motility was diagnosed using the Chicago classification v3.0. First, the locations of the upper esophageal sphincter, transition zone, lower esophageal sphincter, esophago-gastric junction, crural diaphragm and stomach were determined, and each swallow was checked manually. Then, the parameters of the Chicago classification were calculated using an analytic program of the Starlet, and diagnoses were made by three experts. Second, all study raw data were analyzed again by the automated diagnostic program. Diagnoses made by the program were compared to those made by experts to evaluate the accuracy of the diagnoses. RESULTS The new diagnostic program could identify the landmarks of each swallow, calculate the parameters and make a final diagnosis within 10 s. The diagnoses made by the automated diagnostic program were not matched to those made by experts in only 10 studies, and the overall accuracy of the new automated diagnostic program thus reached 97.8% (435/445). CONCLUSIONS The new automated diagnostic program for HREM is clinically useful in terms of high diagnostic accuracy and time-saving.

Abstract
INTRODUCTION Achalasia is a primary motor disorder of the oesophagus characterised by absence of peristalsis and insufficient lower oesophageal sphincter relaxation. With new advances and developments in achalasia management, there is an increasing demand for comprehensive evidence-based guidelines to assist clinicians in achalasia patient care. METHODS Guidelines were established by a working group of representatives from United European Gastroenterology, European Society of Neurogastroenterology and Motility, European Society of Gastrointestinal and Abdominal Radiology and the European Association of Endoscopic Surgery in accordance with the Appraisal of Guidelines for Research and Evaluation II instrument. A systematic review of the literature was performed, and the certainty of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation methodology. Recommendations were voted upon using a nominal group technique. RESULTS These guidelines focus on the definition of achalasia, treatment aims, diagnostic tests, medical, endoscopic and surgical therapy, management of treatment failure, follow-up and oesophageal cancer risk. CONCLUSION These multidisciplinary guidelines provide a comprehensive evidence-based framework with recommendations on the diagnosis, treatment and follow-up of adult achalasia patients.

Abstract
BACKGROUND Several patients in gastroenterology practice present with esophageal symptoms, and in case of normal endoscopy with biopsies, high-resolution manometry (HRM) is often the next step. Our aim was to develop a European consensus on the clinical application of esophageal HRM, to offer the clinician guidance in selecting patients for HRM and using its results to optimize clinical outcome. METHODS A Delphi consensus was initiated with 38 multidisciplinary experts from 16 European countries who conducted a literature summary and voting process on 71 statements. Quality of evidence was evaluated using grading of recommendations assessment, development, and evaluation (GRADE) criteria. Consensus (defined as >80% agreement) was reached for 33 statements. RESULTS The process generated guidance on when to consider esophageal HRM, how to perform it, and how to generate the report. The Delphi process also identified several areas of uncertainty, such as the choice of catheters, the duration of fasting and the position in which HRM is performed, but recommended to perform at least 10 5-ml swallows in supine position for each study. Postprandial combined HRM impedance is considered useful for diagnosing rumination. There is a large lack of consensus on treatment implications of HRM findings, which is probably the single area requiring future targeted research. CONCLUSIONS AND INFERENCES A multinational and multidisciplinary group of European experts summarized the current state of consensus on technical aspects, indications, performance, analysis, diagnosis, and therapeutic implications of esophageal HRM.

Application of a novel straight leg raise test during high-resolution manometry can predict esophageal contractile reserve in patients with gastroesophageal reflux disease. Neurogastroenterol Motil 2021; 33:e13996. [PMID: 33006260 DOI: 10.1111/nmo.13996] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2020] [Revised: 07/02/2020] [Accepted: 09/02/2020] [Indexed: 12/06/2022]
Abstract
BACKGROUND/AIM Increased intra-abdominal pressure from abdominal compression augments esophageal peristalsis during high-resolution manometry (HRM), and straight leg raise (SLR) while supine increases intra-abdominal pressure. We determined if water swallows performed during SLR can mimic contraction reserve seen with multiple rapid swallows (MRS). METHODS Consecutive patients evaluated for GERD symptoms completed validated GERD questionnaires, esophageal HRM, and upper endoscopy. Distal contractile integral (DCI) was analyzed during single water swallows (10 × 5 mL), MRS (5 × 2 mL), and during SLR (5x5 mL). Peristaltic breaks were measured using software tools with a 20 mm Hg isobaric contour. Univariate correlational analyses were performed to compare esophageal motor patterns and DCI values during single water swallows, MRS, and SLR. RESULTS Of 103 study patients (mean age: 46.7 ± 12.3 years, 56.3% female), 50 (48.5%) had ineffective esophageal motility (IEM). Contraction reserve was observed on MRS in 62% with IEM, and 35.8% with normal motility (p = 0.008). DCI was significantly higher during SLR compared to mean single swallow DCI in both IEM and normal motility patients (p < 0.001 for each comparison). In IEM patients, SLR significantly reduced swallows with peristaltic breaks (6.1 ± 3.7 vs 3.6 ± 3.6; p < 0.001) and shortened the length of the largest break (4.8 ± 3.4 vs 3.0 ± 3.0 cm; p < 0.001). DCI response following MRS correlated with DCI with swallows during SLR, with a correlational coefficient (Pearson's r) of 0.70 (p < 0.001). CONCLUSIONS Swallowing against the resistance of increased intra-abdominal pressure from SLR improves esophageal body peristaltic performance and predicts esophageal body contraction reserve.

Abstract
High-resolution manometry (HRM) is the primary method for diagnosing esophageal motility disorders and its interpretation and classification are based on variables (features) from data of each swallow. Modeling and learning the semantics directly from raw swallow data could not only help automate the feature extraction, but also alleviate the bias from pre-defined features. With more than 32-thousand raw swallow data, a generative model using the approach of variational auto-encoder (VAE) was developed, which, to our knowledge, is the first deep-learning-based unsupervised model on raw esophageal manometry data. The VAE model was reformulated to include different types of loss motivated by domain knowledge and tuned with different hyper-parameters. Training of the VAE model was found sensitive on the learning rate and hence the evidence lower bound objective (ELBO) was further scaled by the data dimension. Case studies showed that the dimensionality of latent space have a big impact on the learned semantics. In particular, cases with 4-dimensional latent variables were found to encode various physiologically meaningful contraction patterns, including strength, propagation pattern as well as sphincter relaxation. Cases with so-called hybrid L2 loss seemed to better capture the coherence of contraction/relaxation transition. Discriminating capability was further evaluated using simple linear discriminative analysis (LDA) on predicting swallow type and swallow pressurization, which yields clustering patterns consistent with clinical impression. The current work on modeling and understanding swallow-level data will guide the development of study-level models for automatic diagnosis as the next stage.

Abstract
BACKGROUND Pseudoachalasia manifests high-resolution manometry (HRM) findings of achalasia but results from a secondary process. We analyzed clinical and HRM characteristics of pseudoachalasia, including malignant and non-malignant subtypes. METHODS High-resolution manometry was retrospectively reviewed in patients with confirmed pseudoachalasia, and corroborated with endoscopic and radiographic studies. A control cohort of idiopathic achalasia patients was identified. Clinical characteristics, Eckardt score, and HRM metrics were extracted from institutional records. Grouped data and medians (interquartile range) were compared between pseudoachalasia and idiopathic achalasia, and between malignant and non-malignant pseudoachalasia, using parametric and non-parametric statistical tests. KEY RESULTS Of 28 pseudoachalasia patients (62.2 ± 2.5 years, 60.7% female), 18 (64.3%) had malignancy, and 10 (35.7%) had non-malignant obstruction. Although Eckardt score did not differentiate pseudoachalasia from 58 achalasia patients (55.9 ± 2.5 years, 53.4% female), weight loss was greater (median 9.1 [5.0-18.5] vs 3.6 [0-9.1] kg, P < .02) with shorter duration of symptoms (median 12.9 [8.0-38.6] vs 36.0 [25.7-45.0] weeks, P < .001] in pseudoachalasia. Esophagogastric junction (EGJ) metrics demonstrated lower mean IRP values and lower EGJ contractile integral in pseudoachalasia (P < .04 for each comparison with idiopathic achalasia). Type 1 pattern was more frequent in pseudoachalasia (39.3% vs 13.8%, P < .008). Pseudoachalasia demonstrated incomplete HRM patterns, with lower rates of lack of peristalsis (79.6%, vs 93.1% in achalasia, P < .05). Despite higher Eckardt scores in malignant vs non-malignant pseudoachalasia (median 8.0 [7.0-9.0] vs 6.0 [3.5-7.8], P < .03], no significant HRM differences were noted. CONCLUSIONS AND INFERENCES Pseudoachalasia manifests with a shorter history, greater weight loss, and incomplete HRM achalasia patterns compared to achalasia.

Abstract
This manuscript summarizes consensus reached by the International Anorectal Physiology Working Group (IAPWG) for the performance, terminology used, and interpretation of anorectal function testing including anorectal manometry (focused on high-resolution manometry), the rectal sensory test, and the balloon expulsion test. Based on these measurements, a classification system for disorders of anorectal function is proposed. Aim to provide information about methods of diagnosis and new classification of functional anorectal disorders to a wide range of specialists general practitioners, therapists, gastroenterologists, coloproctologists all who face the manifestations of these diseases in everyday practice and determine the diagnostic and therapeutic algorithm. Current paper provides agreed statements of IAPWG Consensus and comments (in italics) of Russian experts on real-world practice, mainly on methodology of examination. These comments in no way intended to detract from the provisions agreed by the international group of experts. We hope that these comments will help to improve the quality of examination based on the systematization of local experience with the use of the methods discussed and the results obtained. Key recommendations: the International Anorectal Physiology Working Group protocol for the performance of anorectal function testing recommends a standardized sequence of maneuvers to test rectoanal reflexes, anal tone and contractility, rectoanal coordination, and rectal sensation. Major findings not seen in healthy controls defined by the classification are as follows: rectoanal areflexia, anal hypotension and hypocontractility, rectal hyposensitivity, and hypersensitivity. Minor and inconclusive findings that can be present in health and require additional information prior to diagnosis include anal hypertension and dyssynergia.

High-resolution manometry in the upright position could improve the manometric evaluation of morbidly obese patients with esophagogastric junction outflow obstruction. Neurogastroenterol Motil 2020; 32:e13924.

Abstract
BACKGROUND Esophagogastric junction outflow obstruction (EGJOO) detected by manometry in the supine position is prevalent in patients with morbid obesity, but not all EGJOOs are clinically significant. We investigated whether including upright swallows during high-resolution manometry (HRM) could help identify non-clinically significant EGJOO in patients with morbid obesity. METHODS We performed a retrospective study of consecutive morbidly obese patients diagnosed with EGJOO by HRM from July 2012 through July 2018. The HRM protocol included 10 supine and five upright 5-mL water swallows. Endoscopy, esophagram, and computed tomography were performed to identify whether the patients should be diagnosed as having clinically significant EGJOO. KEY RESULTS A total of 230 patients with morbid obesity underwent HRM in the supine position during the study period. Fifty (21.7%) patients were diagnosed with EGJOO, among which 32 completed HRM both in the supine and upright positions. Only 8/32 patients were diagnosed with EGJOO in an upright position. Fewer artifacts were displayed in esophageal pressure topography in the upright position. None of the 32 patients could be diagnosed as clinically significant EGJOO based on all the examinations. Median esophageal gastric junction pressure, integrated relaxation pressure, and distal contractile integral were higher, and median distal latency was longer in the supine position compared with the upright position (all P < .05). CONCLUSIONS AND INFERENCES Esophagus manometry in the upright position could reduce EGJOO overdiagnosis in patients with morbid obesity. Prolongation of the HRM study with some swallows in the upright position could be recommended in obese patients.

Abstract
PURPOSE OF REVIEW Objective measurement of anorectal sensorimotor function is a requisite component in the clinical evaluation of patients with intractable symptoms of anorectal dysfunction. Regrettably, the utility of the most established and widely employed investigations for such measurement (anorectal manometry (ARM), rectal sensory testing and the balloon expulsion test) has been limited by wide variations in clinical practice. RECENT FINDINGS This article summarizes the recently published International Anorectal Physiology Working Group (IAPWG) consensus and London Classification of anorectal disorders, together with relevant allied literature, to provide guidance on the indications for, equipment, protocol, measurement definitions and results interpretation for ARM, rectal sensory testing and the balloon expulsion test. The London Classification is a standardized method and nomenclature for description of alterations in anorectal motor and sensory function using office-based investigations, adoption of which should bring much needed harmonization of practice.

Abstract
Esophageal symptoms are common and may indicate the presence of gastroesophageal reflux disease (GERD), structural processes, motor dysfunction, behavioral conditions, or functional disorders. Esophageal physiologic tests are often performed when initial endoscopic evaluation is unrevealing, especially when symptoms persist despite empiric management. Commonly used esophageal physiologic tests include esophageal manometry, ambulatory reflux monitoring, and barium esophagram. Functional lumen imaging probe (FLIP) has recently been approved for the evaluation of esophageal pressure and dimensions using volumetric distension of a catheter-mounted balloon and as an adjunctive test for the evaluation of symptoms suggestive of motor dysfunction. Targeted utilization of esophageal physiologic tests can lead to definitive diagnosis of esophageal disorders but can also help rule out organic disorders while making a diagnosis of functional esophageal disorders. Esophageal physiologic tests can evaluate obstructive symptoms (dysphagia and regurgitation), typical and atypical GERD symptoms, and behavioral symptoms (belching and rumination). Certain parameters from esophageal physiologic tests can help guide the management of GERD and predict outcomes. In this ACG clinical guideline, we used the Grading of Recommendations Assessment, Development and Evaluation process to describe performance characteristics and clinical value of esophageal physiologic tests and provide recommendations for their utilization in routine clinical practice.

Abstract
Achalasia is an esophageal motility disorder characterized by aberrant peristalsis and insufficient relaxation of the lower esophageal sphincter. Patients most commonly present with dysphagia to solids and liquids, regurgitation, and occasional chest pain with or without weight loss. High-resolution manometry has identified 3 subtypes of achalasia distinguished by pressurization and contraction patterns. Endoscopic findings of retained saliva with puckering of the gastroesophageal junction or esophagram findings of a dilated esophagus with bird beaking are important diagnostic clues. In this American College of Gastroenterology guideline, we used the Grading of Recommendations Assessment, Development and Evaluation process to provide clinical guidance on how best to diagnose and treat patients with achalasia.

Abstract
PURPOSE OF REVIEW In the absence of mucosal or structural disease, the aim of investigating the oesophagus is to provide clinically relevant measurements of function that can explain the cause of symptoms, identify pathology and guide effective management. One of the most notable recent advances in the field of oesophageal function has been high-resolution manometry (HRM). This review explores how innovation in HRM has progressed and has far from reached a plateau. RECENT FINDINGS HRM technology, methodology and utility continue to evolve; simple additions to the swallow protocol (e.g. eating and drinking), shifting position, targeting symptoms and adding impedance sensors to the HRM catheter have led to improved diagnoses, therapeutic decision-making and outcomes. Progress in HRM persists and shows little sign of abating. The next iteration of the Chicago Classification of motor disorders will highlight these advances and will also identify opportunities for further research and innovation.

Abstract
Aim. Current recommendations of the Russian Gastroenterological Association on clinical use of high-resolution manometry in diagnosis of esophageal disorders are intended to assist in clinical decision making, terminology standardisation and interpretation of clinical data.Key points. In 2018, a joint meeting of the Russian Gastroenterological Association and Russian Neurogastroenterology and Motility Group approved unified terminology and classification of esophageal motor function disorders for high-resolution manometry diagnosis.Gastrointestinal patient complaints typically concern esophageal disorders such as dysphagia, regurgitation, heart-burn, chest pain or belching. To exclude erosive and ulcerative lesions, eosinophilic esophagitis and organic changes, esophagogastroduodenoscopy and biopsy are recommended in pre-treatment. Upon excluding mucosal lesions and esophageal lumen obstruction as causal for symptoms, use of high-resolution manometry is recommended. This method of esophageal examination has become the “gold standard” in diagnosis of motor disorders.High-resolution manometry enables detailed investigation of integral quantitative and qualitative characteristics of esophagus motor function and specific related disorders, analysis of esophageal contractile propagation and strictly coordinated synchronous peristalsis of upper esophageal sphincter, esophagus and lower esophageal sphincter, which malfunction may provoke development of achalasia, esophagospasm, hiatal hernia, ineffective eso pha geal motility and other motor disorders.Conclusion. High-resolution manometry is a relatively new method for study of esophagus motor function gaining increasingly wide application in clinical practice. It enables a medical professional to obtain evidence that may critically affect the choice of optimal patient care strategy and effective treatment. Current recommendations are based on an extensive review of up-to-date information and will be updated with new corpus of clinical data and assessment emerging in evidential medicine to provide gastroenterologists country-wide with latest scientific and practical guidelines.

Role of Rapid Drink Challenge During Esophageal High-resolution Manometry in Predicting Outcome of Peroral Endoscopic Myotomy in Patients With Achalasia. J Neurogastroenterol Motil 2020; 26:204-214.

Abstract
Background/Aims Peroral endoscopy myotomy (POEM) is effective to treat achalasia. We aim to determine POEM effect on esophageal function and search for predictive factors of response to POEM and co-occurrence of gastroesophageal reflux disease (GERD). Methods A total of 64 untreated achalasia patients who underwent high-resolution manometry (HRM) before and 3 months after POEM were retrospectively included. Response to treatment was defined as an Eckardt score < 3. Reflux symptoms and patient's satisfaction were evaluated. Data were compared using paired t test, Chi-square test or log rank test. Results The 2-year success rate in response to POEM was 90%. All responders reported being satisfied while only 33% of non-responders did (P < 0.001) and 64% of patients with reflux symptoms were satisfied versus 96% of those without (P = 0.009). On HRM, the integrated relaxation pressure and the contractile pattern changed significantly after POEM but were not predictive of response. Between pre and post POEM HRM, a decrease in maximal esophageal pressurization during rapid drink challenge (RDC) was associated with a better response rate than an increase of pressurization (91% vs 50%, P = 0.004). As evidenced by pH monitoring performed after POEM, GERD was pathological or borderline in 50% of patients (18/36) while only 19% (11/59) reported clinically significant reflux symptoms. On post POEM HRM, maximal esophageal pressurization during RDC was lower in patients with pathological or borderline GERD compared to those without (P = 0.054). Conclusions Esophageal HRM parameters changed significantly after POEM. Maximal esophageal pressurization during RDC may be useful to predict outcome.

Abstract
Esophageal achalasia is a primary motility disorder characterized by insufficient lower esophageal sphincter relaxation and loss of esophageal peristalsis. Achalasia is a chronic disease that causes progressive irreversible loss of esophageal motor function. The recent development of high-resolution manometry has facilitated the diagnosis of achalasia, and determining the achalasia subtypes based on high-resolution manometry can be important when deciding on treatment methods. Peroral endoscopic myotomy is less invasive than surgery with comparable efficacy. The present guidelines (the "2019 Seoul Consensus on Esophageal Achalasia Guidelines") were developed based on evidence-based medicine; the Asian Neurogastroenterology and Motility Association and Korean Society of Neurogastroenterology and Motility served as the operating and development committees, respectively. The development of the guidelines began in June 2018, and a draft consensus based on the Delphi process was achieved in April 2019. The guidelines consist of 18 recommendations: 2 pertaining to the definition and epidemiology of achalasia, 6 pertaining to diagnoses, and 10 pertaining to treatments. The endoscopic treatment section is based on the latest evidence from meta-analyses. Clinicians (including gastroenterologists, upper gastrointestinal tract surgeons, general physicians, nurses, and other hospital workers) and patients could use these guidelines to make an informed decision on the management of achalasia.

Prospective serial diagnostic study: the effects of position and provocative tests on the diagnosis of oesophageal motility disorders by high-resolution manometry.

Abstract
BACKGROUND Standard high-resolution manometry (HRM) protocols are based on 10 single water swallows acquired in the supine position. AIMS To assess the impact of position, rapid drink challenge and solid test meal on the diagnosis of oesophageal motility disorders. METHODS Seventy-two healthy volunteers (20-76 years) and 366 consecutive patients (18-90 years) completed HRM with 10 single water swallows in the supine and upright positions. Rapid drink challenge was performed twice, before and after the solid test meal. Diagnosis based on single water swallows in the supine position (Chicago Classification v3.0) was compared with results in the upright position and with provocative tests. RESULTS Overall, diagnostic agreement in the supine and upright positions was present in 296/438 (67.6%) subjects. This increased to 90.0% when ineffective oesophageal motility was considered with normal motility. Integrated relaxation pressure was 4 mm Hg higher in the supine position. There was a higher prevalence of inconsistent, likely false positive, diagnoses of outlet obstruction in the supine compared to the upright position (16/20 vs 1/4 patients, P = 0.0007). Similarly, the difference in concordance for the diagnosis of oesophago-gastric junction obstruction or achalasia between single water swallows in the supine and upright positions with solid test meal was significant (12/29 (41.4%) vs 12/14 (85.7%), P = 0.0087). CONCLUSION Diagnostic agreement for oesophageal motility disorders based on single water swallows in the upright and supine positions was moderate, with frequent discordant findings for ineffective motility and outlet obstruction. HRM studies can be performed in either position, using appropriate reference values. Rapid drink challenge or solid test meal can resolve diagnostic discrepancies.

Abstract
BACKGROUND A novel three-dimensional high-resolution esophageal manometry provides a dynamic 360° representation of the pressure at the esophagogastric junction. AIMS To describe the three-dimensional high-resolution esophageal manometry patterns of achalasia. METHODS We retrospectively included all consecutive patients who underwent three-dimensional high-resolution esophageal manometry before and after treatment (pneumatic dilatation or per-oral endoscopic myotomy) for achalasia between November 2016 and July 2017. The distribution of the pressures at the esophagogastric junction on three-dimensional high-resolution esophageal manometry was determined. RESULTS Eighteen patients were included. Mean integrated relaxation pressure was 20.7 mmHg, and median (range) Eckardt score was 7 (4-10). Nine patients were treated by pneumatic dilatation and seven by myotomy. Nine patients underwent three-dimensional high-resolution esophageal manometry after treatment. Before treatment, the esophagogastric junction pressure distribution was best observed at end expiration and during the 4 s of the integrated relaxation pressure measurement. During the integrated relaxation pressure, the lower esophageal sphincter was asymmetric in 12 patients with a high-pressure zone between the left and the posterior side of the esophagogastric junction. After treatment, five patients had a residual high-pressure point on the left or the posterior side of the esophagogastric junction. CONCLUSIONS Three-dimensional high-resolution esophageal manometry allows a simple assessment of the pressure topography at the EGJ. In patients with achalasia, we found the esophagogastric junction pressure to be asymmetric with a peak pressure on the greater curvature side. Three-dimensional high-resolution esophageal manometry has the potential to guide initial and redo treatments.

Abstract
BACKGROUND This manuscript summarizes consensus reached by the International Anorectal Physiology Working Group (IAPWG) for the performance, terminology used, and interpretation of anorectal function testing including anorectal manometry (focused on high-resolution manometry), the rectal sensory test, and the balloon expulsion test. Based on these measurements, a classification system for disorders of anorectal function is proposed. METHODS Twenty-nine working group members (clinicians/academics in the field of gastroenterology, coloproctology, and gastrointestinal physiology) were invited to six face-to-face and three remote meetings to derive consensus between 2014 and 2018. KEY RECOMMENDATIONS The IAPWG protocol for the performance of anorectal function testing recommends a standardized sequence of maneuvers to test rectoanal reflexes, anal tone and contractility, rectoanal coordination, and rectal sensation. Major findings not seen in healthy controls defined by the classification are as follows: rectoanal areflexia, anal hypotension and hypocontractility, rectal hyposensitivity, and hypersensitivity. Minor and inconclusive findings that can be present in health and require additional information prior to diagnosis include anal hypertension and dyssynergia. CONCLUSIONS AND INFERENCES This framework introduces the IAPWG protocol and the London classification for disorders of anorectal function based on objective physiological measurement. The use of a common language to describe results of diagnostic tests, standard operating procedures, and a consensus classification system is designed to bring much-needed standardization to these techniques.

Abstract
Background After the first-cycle of neoadjuvant chemotherapy (NAC), many patients with esophageal squamous cell carcinoma (ESCC) experience a stable disease (SD)/progressive disease (PD) response. Clinically, SD patients are recommended to receive a second cycle of NAC, and PD patients are recommended to undergo surgery if possible. However, we found some PD tumors shrank after a second-cycle of NAC. Some first-cycle SD patients may develop PD after second-cycle NAC and lose the chance of surgery. Thus, how to predict the response to second-cycle NAC for first-cycle SD/PD patients is important for clinical practice. Methods This retrospective single-center study was approved by the Institutional Review Board at the Affiliated Cancer Hospital of Zhengzhou University/Henan Cancer Hospital. We retrospectively reviewed patients with ESCC who had NAC and evaluated SD by computed tomography (CT) scan after the first-cycle between March 9, 2013 and October 24, 2016. Univariate and multivariate analyses of the clinical parameters were performed to identify markers predictive of a clinically response by using IBM-SPSS version 23. Results There were 64 patients included in the study. Thirty-one first-cycle NAC-SD/PD patients (48.4%) showed a response after second-cycle NAC, which was significantly correlated with alleviated dysphagia (P=0.006) and smoking (P=0.025). In the multivariate analyses, alleviated dysphagia [odds ratio (OR) 3.978; 95% confidence interval (CI), 1.335-11.856; P=0.013] was identified as the only independent predictive factor for tumor response after second-cycle of NAC for first-cycle SD/PD patients. Conclusions Alleviated dysphagia might be a useful factor to predict the response to second-cycle NAC for first-cycle SD/PD patients.

Abstract
Esophageal cancer represents one of the most lethal forms of malignancy. The growing incidence of esophageal adenocarcinoma represents an emerging public health concern. This review article summarizes current diagnostic, management, and therapeutic practices of premalignant conditions of the esophagus including Barrett's esophagus, tylosis, granular cell tumors, achalasia, and the ingestion of caustic substances. Our report provides clinicians and academics with a global clinical perspective regarding presentation, surveillance guidelines, and therapeutic management of these esophageal conditions.
