RESUMEN
BACKGROUND/PURPOSE: Peroral endoscopic myotomy (POEM), a novel minimally invasive treatment for esophageal achalasia, has been shown to be effective and safe for both adult and pediatric patients. However, studies on its application in children in Taiwan and its impact on growth and esophageal motility are lacking. METHODS: We conducted a retrospective study on consecutive pediatric patients who were diagnosed with esophageal achalasia at National Taiwan University Hospital and underwent POEM during 2015-2022. Disease characteristics and treatment outcomes were analyzed. RESULTS: Ten patients (age 16.9 ± 3.1 years), nine newly diagnosed and one previously treated with pneumatic dilatation, underwent POEM for achalasia (type I/II/III: 3/7/0). Average symptom duration before diagnosis was 19.4 ± 19.9 months, mean POEM procedure time was 83.6 ± 30.7 min, and clinical success (Eckardt score ≤3) was achieved in all patients. Eight patients experienced mild adverse events during POEM, but none required further endoscopic or surgical intervention. Over a mean follow-up period of 3.7 ± 1.6 years, mean Eckardt score decreased significantly from 5.7 ± 2.4 to 1.1 ± 0.7 (p = 0.0001). The BMI z-score also increased significantly after POEM (p = 0.023). Five patients received follow-up high-resolution impedance manometry (HRIM), and all had improved lower esophageal sphincter resting pressures (p = 0.011), body contractility, and bolus transit (p = 0.019). CONCLUSION: POEM is an effective and safe treatment for pediatric achalasia in Taiwan. Early diagnosis and treatment with POEM may help to restore esophageal function and nutrition status in children.

In recent years, the high-resolution manometry (HRM) technique has been increasingly used to study esophageal and colonic pressurization and has become a standard routine for discovering mobility disorders. In addition to evolving guidelines for the interpretation of HRM like Chicago standard, some complexities, such as the dependency of normative reference values on the recording device and other external variables, still remain for medical professions. In this study, a decision support framework is developed to aid the diagnosis of esophageal mobility disorders based on HRM data. To abstract HRM data, Spearman correlation is employed to model the spatio-temporal dependencies of pressure values of HRM components and convolutional graph neural networks are then utilized to embed relation graphs to the features vector. In the decision-making stage, a novel Expert per Class Fuzzy Classifier (EPC-FC) is presented that employs the ensemble structure and contains expertized sub-classifiers for recognizing a specific disorder. Training sub-classifiers using the negative correlation learning method makes the EPC-FC highly generalizable. Meanwhile, separating the sub-classifiers of each class gives flexibility and interpretability to the structure. The suggested framework is evaluated on a dataset of 67 patients in 5 different classes recorded in Shariati Hospital. The average accuracy of 78.03% for a single swallow and 92.54% for subject-level is achieved for distinguishing mobility disorders. Moreover, compared with the other studies, the presented framework has an outstanding performance considering that it imposes no limits on the type of classes or HRM data. On the other hand, the EPC-FC outperforms other comparative classifiers such as SVM and AdaBoost not only in HRM diagnosis but also on other benchmark classification problems.

BACKGROUND: High-resolution manometry, which measures esophageal luminal pressure changes after swallowing, could shed more light on food-transport dynamics after pharyngeal/esophageal reconstruction. This prospective cohort study assessed the influence of two head-and-neck and esophageal tumor-resection and reconstruction approaches on esophageal pressure. METHODS: The cohort consisted of 17 patients who underwent esophageal/pharyngeal resection/reconstruction for cancer and then participated in postoperative high-resolution manometry. Five healthy controls also underwent manometry for comparison. RESULTS: Partial pharyngectomy with patch grafts associated with smooth and continuous esophageal/pharyngeal movement. By contrast, surgery that removed the thoracic esophagus led to complete loss of peristalsis and poor food transport. CONCLUSIONS: High-resolution manometry effectively characterized the changes in food-transport dynamics caused by pharyngeal/esophageal resection/reconstruction. These findings suggest that continuous and smooth movement of the pharynx and esophagus is important for swallowing and high resolution manometry could be useful in patients after pharyngeal/esophageal resection/reconstruction.

【Objective】 To explore the characteristics of esophageal motility and reflux of endoscopic-negative heartburn patients based on the Lyon Consensus Diagnostic Criteria and discuss the differential diagnosis value of the mean nocturnal baseline impedance （MNBI） and the postreflux swallow-induced peristaltic wave （PSPW） index for reflux hypersensitivity （RH） and functional heartburn （FH） patients. 【Methods】 We enrolled 132 patients with heartburn as the main symptom who visited the Gastroenterology Department of our hospital from January 2017 to June 2021， including 24 in the non-erosive reflux disease （NERD） group， 24 in the RH group， and 84 in the FH group. All the patients completed gastroscopy， esophageal high-resolution manometry and 24h-pH impedance monitoring. We analyzed and compared the related indexes of esophageal motility and reflux. The receiver operating characteristic （ROC） curve was used to analyze the esophageal proximal MNBI， distal MNBI， and PSPW indexes for the differential diagnosis of RH and FH. 【Results】 The lower esophageal sphincter （LES） average resting pressure， LES residual pressure and intact relaxation pressure （IRP） in NERD were lower than those in RH and FH （P0.05）. When the proximal MNBI， distal MNBI， and PSPW indexes were used alone respectively to diagnose RH， the area under the ROC curve was 0.480， 0.810， 0.682， respectively， with the sensitivities being 87.5%， 100% and 91.7%， and the specificities being 26.2%， 66.7% and 51.2%， respectively. 【Conclusion】 NERD patients have obvious abnormal esophageal dynamics， mainly manifested as LES relaxation， which further aggravates the pathological acid reflux， while patients with RH and FH are mainly exposed to physiological acid or non-acid reflux. In patients with endoscopic negative heartburn， distal MNBI value can improve the clinical diagnosis rate of RH and help distinguish RH from FH.
RESUMEN
OBJECTIVE: To analyze the esophageal dynamics in patients with gastroesophageal reflux disease (GERD) and with refractory cough while undergoing esophageal high-resolution manometry (HRM). METHODS: A total of 32 patients with GERD and with refractory cough and 48 patients with GERD admitted to our hospital from February 2019 to July 2020 were assigned to the combined group and the GERD group, respectively, and 40 healthy volunteers were assigned to the healthy group. All the patients underwent HRM. The lower esophageal sphincter (LES) and the upper esophageal sphincter (UES) parameters, the types of peristalsis of the esophageal body, the esophageal body motility, the i relaxation of LES and UES incidence rates, and the esophageal body motility disorders were compared among the three groups. RESULTS: The combined group and the GERD group had lower esophageal sphincter pressure (LESP) levels and lower 4-s integrated relaxation pressure (4 s IRP) levels, shorter lower esophageal sphincter lengths (LESL), and higher frequencies and longer durations of transient lower esophageal sphincter relaxation (TLESR) compared with the healthy group (P < 0.05). The upper esophageal sphincter lengths (UESL) in the GERD group were longer than they were in the healthy group (P < 0.05). Compared with the healthy group and the GERD group, the combined group had longer distal latencies (DL), break distances, and peristaltic breaks (PB), longer large and small peristaltic breaks, a greater number of ineffective swallows, lower upper esophageal sphincter pressure (UESP) levels, distal contraction integrals (DCI), contractile front velocities (CFV), and a higher incidence rate of esophageal body motility disorders (P < 0.05). CONCLUSION: Patients with GERD and with refractory cough often also have esophageal body motility disorders, longer PB, elevated UESP levels, and lower DCI. HRM can be used to objectively evaluate the esophageal dynamics and to differentiate among diseases.
RESUMEN
Objective: To analyze the clinical characteristics and pathogenesis of refractory gastroesophageal reflux disease(RGERD). Methods: The patients with acid regurgitation, heartburn and extraesophageal symptoms were enrolled in the study from November 2015 to September 2017 at Peking University Third Hospital. All the subjects filled the informed consent.Questionnaire, SCL-90, SAS and SDS scales were recorded. A 24 hour pH-impedance monitoring and esophageal high resonance manometry were carried out. According to the response to proton pump inhibitor(PPI), the patients were divided into RGERD and non-RGERD(NRGERD)groups. The clinical characteristics were compared between these two groups. Logistic regression was used to analyze the risk factors of RGERD. Results: One hundred and nineteen patients were finally enrolled in the study including 61 RGERD (51.3%) and 58 NRGERD patients (48.7%).The body mass index (BMI) and rates of, typical GER symptoms including acid regurgitation in RGERD patients were significantly lower than those in NRGERD patients (P<0.05).While the atypical GER symptoms such as poststernal discomfort or chest pain were more common in RGERD group (P<0.05).RGERD patients presented less acid reflux events and lower proximal segment reflux ratio than NRGERD patients. No obvious differences were found in the manometry metrics between these two groups. The scores of somatization, depression and hostility in RGERD patients by SCL-90 scales were significantly higher than those in NRGERD patients (P<0.05), and depression score was an independent risk factor for RGERD [OR=3.915 (95%CI 1.464-10.466), P =0.007]. Conclusions: RGERD patients present more atypical symptoms and pathological non-acid reflux.Depression is an independent risk factor for RGERD.

PURPOSE OF REVIEW: Here, we discuss how esophageal motor testing plays important roles in patients with suspected gastroesophageal reflux disease (GERD). In addition to guiding appropriate placement of catheters for ambulatory reflux monitoring, esophageal high-resolution manometry (HRM) rules out confounding diagnoses, such as achalasia spectrum disorders, that can present with symptoms similar to that of GERD, but are managed very differently. RECENT FINDINGS: HRM performed with impedance in the post-prandial setting (PP-HRIM) can assess for rumination syndrome or supragastric belching, which should be directed towards behavioral interventions. The recent GERD Classification of Motor Function recommends a hierarchical approach, focusing on (1) the esophagogastric junction (EGJ), (2) the esophageal body, and (3) esophageal contraction reserve, which can be assessed with provocative maneuvers at HRM, such as multiple rapid swallows (MRS). This approach can inform the appropriate tailoring of antireflux surgery. Novel esophageal motility metrics, such as the EGJ-contractile integral from HRM, or post-reflux swallow-induced peristaltic wave indices from 24-h pH-impedance monitoring, may also assist with GERD diagnosis. Assessment of esophageal motor function can contribute in a significant manner to the care of patients with suspected GERD, particularly when esophageal symptoms do not improve with antisecretory therapy, and/or when surgical or endoscopic antireflux therapies are under consideration.

INTRODUCTION: Botulinum toxin injection is known to be efficient to treat achalasia. We conducted a randomized trial in order to evaluate its efficacy to treat symptomatic hypercontractile esophageal disorders as characterized by esophageal high-resolution manometry. METHODS: Patients with significant dysphagia and/or thoracic pain related to an hypercontractile esophageal motility disorder as defined by the Chicago Classification were randomized to receive an injection of botulinum toxin (100 U in 10 points in the distal part of the esophageal wall) or a sham procedure. Symptoms were assessed at 3 months with the Eckardt score. Patients could receive a first or second botulinum toxin injection 1 month later if symptoms persisted. RESULTS: Twenty-three patients (13 women, mean age 60 years) were included: 13 received botulinum toxin injection, and 10 a sham procedure. The improvement of symptoms at 3 months was significant compared to baseline, but similar in the active treatment and sham procedure arms. However, there was no change in quality of life scores. Seventeen patients received a second injection at 4 months. There was a significant trend toward improvement of symptoms up to the end of follow-up at 12 months, without a significant relationship with the administration of botulinum toxin. DISCUSSION: Botulinum toxin injection is not superior to a sham procedure to improve symptoms related to hypercontractile esophageal disorders, suggesting an important placebo effect in for this type of disease. This observation must be taken into account when evaluating more aggressive therapies such as endoscopic myotomy (clinicaltrials.gov: NCT01955174).

Esophageal high-resolution manometry (HRM) has advanced the understanding of esophageal motor function and the ability to diagnose and manage disorders of esophageal motility. In this review, we describe the indications for and the technical performance of HRM. The Chicago classification of esophageal motor function, now in its third iteration, streamlines and standardizes the nomenclature and basic interpretation of HRM data depicted as Clouse topographic plots. In clinical practice, HRM is an important diagnostic test for patients with dysphagia as well as patients with suspected gastroesophageal reflux disease (GERD), particularly in those patients with a suboptimal symptomatic response to antisecretory therapy. HRM can support diagnoses such as achalasia, as well as provide evidence for behavioral disorders such as rumination syndrome or supragastric belching with the assistance of postprandial HRM with impedance. Further, the GERD classification of motor function introduces a three-part hierarchical evaluation of esophageal motor function in GERD, highlighting the value of assessment of esophageal contractile reserve through provocative maneuvers during HRM such as multiple rapid swallows.

Diagnostic criteria for esophageal motor disorders have recently been updated with the advent of high-resolution manometry that gives a precise mapping of peristaltic abnormalities and an indirect view of bolus transit problems. Achalasia, the best-defined motor disorder, is now divided in subsets of manometric phenotypes that predict outcome of treatment and guide our therapeutic approach. Pharmacological therapy using smooth muscle relaxants for spastic esophageal disorders remains poorly effective and used only as a bridge to more effective therapies : endoscopic balloon dilation and surgical myotomy are both effective therapies in achalasia, myotomy being considered as the preferred approach in children because it is aimed to be definitive, while dilations usually have to be repeated. Recently, peroral endoscopic myotomy was introduced as an alternative to surgical myotomy for achalasia, and was rapidly adopted in tertiary referral centers. Showing excellent short-term results, this technique might be also proposed for other esophageal spastic disorders. Gastroesophageal reflux disease and eosinophilic esophagitis, two prevalent diseases in children that may be associated with hypotensive and hypertensive peristaltic abnormalities, have to be searched because specific effective therapies exist for these diseases that may cure the motility disorders.

INTRODUCTION: Achalasia is a rare esophageal motility disorder. Much of the literature is based on the adult population. In adults, guidance of therapeutic approach by manometric findings has led to improvement in patient outcome. Promising results have been achieved with novel therapies such as PerOral Endoscopic Myotomy (POEM). Areas covered: In this review, we provide an overview of the novel diagnostic and therapeutic tools for achalasia management and in what way they will relate to the future management of pediatric achalasia. We performed a PubMed and EMBASE search of English literature on achalasia using the keywords 'children', 'achalasia', 'pneumatic dilation', 'myotomy' and 'POEM'. Cohort studies < 10 cases and studies describing patients ≥ 20 years were excluded. Data regarding patient characteristics, treatment outcome and adverse events were extracted and presented descriptively, or pooled when possible. Expert commentary: Available data report that pneumatic dilation and laparoscopic Heller's myotomy are effective in children, with certain studies suggesting lower success rates in pneumatic dilation. POEM is increasingly used in the pediatric setting with promising short-term results. Gastro-esophageal reflux disease (GERD) may occur post-achalasia intervention due to disruption of the LES and therefore requires diligent follow-up, especially in children treated with POEM.

BACKGROUND: To investigate the relationship between endoscopic and esophageal manometric hiatus hernia (HH). METHODS: Forty-six gastroesophageal reflux disease patients with endoscopic HH under maintenance therapy were recruited. Endoscopy was performed on all patients in a fully conscious state. Endoscopic HH was defined as apparent separation greater than 1 cm of the lower margin of the esophageal palisade vessels and the diaphragm hiatus on endoscopy under deep inspiration. Esophageal manometry was conducted using high-resolution manometry (HRM). The length between the lower margin of the lower esophageal sphincter and pulmonary inversion point was measured 10 times. The mean and maximum of the length was then calculated. RESULTS: The mean HH length on HRM was 0 cm (0-0) [median (25th to 75th percentile)], 0 cm (0-0), 0.5 cm (0-1.1), and 2.2 cm (1.3-2.5) in the groups with endoscopic HH lengths of 1-2, 2-3, 3-4, and 4-5 cm, respectively. The maximum HH length on HRM was 0 cm (0-0), 0 cm (0-0), 0.8 cm (0-1.4), and 2.4 cm (1.5-2.9) in the 1-2, 2-3, 3-4, and 4-5 cm endoscopic HH groups, respectively. The mean and maximum HH lengths increased significantly in the group with an endoscopic HH length of 4-5 cm compared with the other groups, but did not differ significantly among the 1-2, 2-3, and 3-4 cm groups. Of patients with endoscopic HH less than 3 cm, few had esophageal manometric HH greater than 2 cm. CONCLUSIONS: Endoscopic diagnosis of HH under deep inspiration is not consistent with esophageal manometric diagnosis, leading to overdiagnosis.

BACKGROUND: Abdominal compression has been implemented as a provocative maneuver in high-resolution impedance manometry (HRIM) to "challenge" normal esophageal physiology with the aim of revealing abnormal motor patterns which may explain symptoms. In this study, we measured the effects of abdominal compression on esophageal functioning utilizing novel pressure-impedance parameters and attempted to identify differences between healthy controls and globus patients. METHODS: Twenty-two healthy volunteers (aged 23-32 years, 41% female) and 22 globus patients (aged 23-72 years, 68% female) were evaluated with HRIM using a 3.2-mm water perfused manometric and impedance catheter. All participants received 10 × 5 mL liquid swallows; healthy controls also received 10 × 5 mL liquid swallows with abdominal compression created using an inflatable cuff. All swallows were analyzed to assess esophageal pressure topography (EPT) and pressure-flow metrics, indicative of distension pressure, flow timing and bolus clearance were derived. KEY RESULTS: The effect of abdominal compression was shown as a greater contractile vigor of the distal esophagus by EPT and higher distension pressure based on pressure-flow metrics. Age and body mass index also increased contractile vigor and distension pressure. Globus patients were similar to controls. CONCLUSIONS AND INTERFERENCES: Intrabolus pressure and contractile vigor are indicative of the physiological modulation of bolus transport mechanisms. Provocative testing by abdominal compression induces changes in these esophageal bolus dynamics.

OBJECTIVES: To study esophageal high resolution manometry (HRM) in systemic sclerosis (SSc) patients and the correlation of findings to The University of California, Los Angeles Scleroderma Clinical Trials Consortium gastrointestinal tract 2.0 (UCLA SCTC_GIT 2.0). METHODS: Forty SSc patients were administered to the UCLA SCTC GIT 2.0. Patients underwent HRM study (Solar GI MMS). HRM data were compared with 15 healthy volunteers. RESULTS: Forty patients with mean age 46 ± 7 years and disease duration 9.3 ± 7 years reported upper (85.7%), lower GI symptoms (75%), while 5% reported no symptoms. Mean ± SD scores of UCLA SCTC_GIT 2.0 items were as follows: reflux 1.2 ± 0.8, distention 1.6 ± 1.2, fecal soiling 0.3 ± 0.9, diarrhea 0.8 ± 1, social 1 ± 1, emotional 1 ± 1.1, constipation 0.5 ± 0.9, and total GIT score 0.9 ± 0.6. Lower esophageal sphincter (LES) pressure and distal esophageal amplitude were significantly lower in SSc patients than controls. Main manometric findings were decreased LES resting pressure (40%) and aperistalsis (40%). Regression analyses showed distal esophageal amplitude and LES resting pressure negatively correlated with reflux score (r = -0.64; p = 0.001 and r = -0.46; p = 0.019, respectively), and total GIT score (r = -0.54; p = 0.007 and r = -0.42; p = 0.03, respectively). LES resting pressure had negative correlations with diarrhea score (r = -0.062; p = 0.002). CONCLUSIONS: Decreased distal esophageal amplitude encountered as hypoperistalsis or even aperistalsis was associated with increased reflux and GIT scores (negatively correlated) UCLA SCTC_GIT 2.0 questionnaires. The GIT2.0 is easy to use and can serve as an indicator that further testing of the GI tract, including the esophagus, is indicated.

Although achalasia presents with typical symptoms such as dysphagia, regurgitation, weight loss, and atypical chest pain, the time until first diagnosis often takes years and is frustrating for patients and nevertheless associated with high costs for the healthcare system. A total of 563 patients were interviewed with confirmed diagnosis of achalasia regarding their symptoms leading to diagnosis along with past clinical examinations and treatments. Included were patients who had undergone their medical investigations in Germany. Overall, 527 study subjects were included (male 46%, female 54%, mean age at time of interview 51 ± 14.8 years). Dysphagia was present in 86.7%, regurgitation in 82.9%, atypical chest pain in 79%, and weight loss in 58% of patients before diagnosis. On average, it took 25 months (Interquartile Range (IQR) 9-65) until confirmation of correct diagnosis of achalasia. Though, diagnosis was confirmed significantly quicker (35 months IQR 9-89 vs. 20 months IQR 8-53; p < 0.01) in the past 15 years. The majority (72.1%) was transferred to three or more specialists. Almost each patient underwent at least one esophagogastroduodenoscopy (94.2%) and one radiological assessment (89.3%). However, esophageal manometry was performed in 70.4% of patients only. The severity of symptoms was independent with regard to duration until first diagnosis (Eckardt score 7.14 ± 2.64 within 12 months vs. 7.29 ± 2.61 longer than 12 months; P = 0.544). Fifty-five percent of the patients primarily underwent endoscopic dilatation and 37% a surgical myotomy. Endoscopic dilatation was realized significantly faster compared to esophageal myotomy (1 month IQR 0-4 vs. 3 months IQR 1-11; p < 0.001). Although diagnosis of achalasia was significantly faster in the past 15 years, it still takes almost 2 years until the correct diagnosis of achalasia is confirmed. Alarming is the fact that although esophageal manometry is known as the gold standard to differentiate primary motility disorders, only three out of four patients had undergone this diagnostic pathway during their diagnostic work-up. Better education of medical professionals and broader utilization of highly sensitive diagnostic tools, such as high-resolution manometry, are strictly necessary in order to correctly diagnose affected patients and to offer therapy faster.

Ineffective esophageal motility (IEM) is the most frequently encountered esophageal motility disorder. Patients may present with a variety of symptoms, such as dysphagia, heartburn, odynophagia, and regurgitation. Over the past years, the landscape of esophageal motility testing has been revolutionized; however, our current treatment options for IEM still remain limited. Previous studies have suggested that buspirone, a serotonin receptor agonist, enhances esophageal peristalsis and lower esophageal sphincter (LES) function. Recent work provides the first evidence that buspirone may influence LES resting pressure in patients with systemic sclerosis. Future research should evaluate whether the beneficial effects of buspirone also apply to the broad clinical entity of esophageal dysphagia patients with IEM.
RESUMEN
BACKGROUND: Intolerance of the esophageal manometry catheter may prolong high-resolution manometry (HRM) studies and increase patient distress. We assessed the impact of obtaining the landmark phase at the end of the study when the patient has acclimatized to the HRM catheter. METHODS: 366 patients (mean age 55.4 ± 0.8 years, 62.0% female) undergoing esophageal HRM over a 1-year period were studied. The standard protocol consisted of the landmark phase, 10 5 mL water swallows 20-30 s apart, and multiple rapid swallows where 4-6 2 mL swallows were administered in rapid succession. The modified protocol consisted of the landmark phase at the end of the study after test swallows. Study duration, technical characteristics, indications, and motor findings were compared between standard and modified protocols. KEY RESULTS: Of the 366 patients, 89.6% underwent the standard protocol (study duration 12.9 ± 0.3 min). In 10.4% with poor catheter tolerance undergoing the modified protocol, study duration was significantly longer (15.6 ± 1.0 min, p = 0.004) despite similar duration of study maneuvers. Only elevated upper esophageal sphincter basal pressures at the beginning of the study segregated modified protocol patients. The 95th percentile time to landmark phase in the standard protocol patients was 6.1 min; as many as 31.4% of modified protocol patients could not obtain their first study maneuver within this period (p = 0.0003). Interpretation was not impacted by shifting the landmark phase to the end of the study. CONCLUSIONS & INFERENCES: Modification of the HRM study protocol with the landmark phase obtained at the end of the study optimizes study duration without compromising quality.

RESUMEN
The Chicago Classification defines esophageal motility disorders in high resolution manometry. This is based on individual scoring of 10 swallows performed in supine position. Disorders of esophago-gastric junction (EGJ) outflow obstruction are defined by a median integrated relaxation pressure above the limit of normal and divided into 3 achalasia subtypes and EGJ outflow obstruction. Major motility disorders (aperistalsis, distal esophageal spasm, and hypercontractile esophagus) are patterns not encountered in controls in the context of normal EGJ relaxation. Finally with the latest version of the Chicago Classification, only two minor motor disorders are considered: ineffective esophageal motility and fragmented peristalsis.
