Abstract
The aim of this review is to provide an overview of per-oral endoscopic myotomy (POEM) and its utilization in non-achalasia disorders of the esophagus. POEM, a relatively novel endoscopic technique, involves submucosal tunneling to access esophageal muscle layers, enabling selective myotomy and mitigating the consequences of motor disorders of the esophagus. POEM is an effective treatment modality for diffuse esophageal spasm providing resolution of chest pain and dysphagia in a majority of patients who have refractory symptoms despite medical therapy. The results of POEM are more equivocal compared to esophagogastric junction outflow obstruction (EGJOO). POEM in EGJOO has been shown to have a 93% clinical success rate in 6 months. POEM appears to be more effective in motor disorders that affect the lower esophageal sphincter, such as EGJOO and opioid-induced esophageal dysfunction. While the current data for POEM in other entities such as DES and HE are positive, more supportive data are required to make POEM a consistent recommendation for patients.

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

Abstract
Distal esophageal spasm is characterized by premature contractions of the distal esophageal smooth muscle leading to non-obstructive dysphagia and non-cardiac chest pain. Diagnosis requires the presence of symptoms along with evidence of at least 20% premature contractions in the setting of a normal lower esophageal sphincter relaxation on high-resolution manometry. New updates to the Chicago Classification have improved the diagnostic accuracy of this method. Functional lumen imaging probe is a growing diagnostic modality that gives a more complete picture of esophageal motility. Pharmacologic treatment remains inadequate. Endoscopic myotomy might be of benefit for non-achalasia esophageal motility disorders. More research is required to better understand the pathophysiology and develop safe and long-lasting management for this disease.

Abstract
Opioids are well known to cause adverse effects on the gastrointestinal tract including nausea, vomiting, and constipation. Data regarding how opioids affect the esophagus are more limited. Opioid-induced esophageal dysfunction (OIED) is a clinical syndrome defined by chronic opioid use (≥3 months), esophageal symptoms (mainly dysphagia), and esophageal motility abnormalities diagnosed by manometry including achalasia type III, hypercontractile esophagus, distal esophageal spasm, and esophagogastric junction outflow obstruction. Up until now, the effect of opioids on esophageal motility assessed by the functional lumen imaging probe (FLIP) had not been described. In this issue of NGM, Patel et al. report that FLIP assessment in patients with esophageal symptoms showed that chronic opioid users have a significant increase in repetitive retrograde contractions, but no significant reduction in distensibility at the esophagogastric junction compared to non-users. Additionally, perceptive symptoms were higher, and quality of life metrics were lower in the chronic opioid users. This review article will discuss our current understanding of OIED and provide context for this latest study in chronic opioid users. Further investigation with larger prospective studies is needed to understand the pathophysiology, diagnosis, and management of OIED.

Abstract
Acute pandysautonomia-associated distal esophageal spasm is a rare disease with an unclear etiology. Here, we describe a 12-year-old boy with an acute pandysautonomia-associated distal esophageal spasm who was treated using a peroral endoscopic myotomy (POEM). The patient's clinical features included recurrent dysphagia, nausea, vomiting, growth retardation, and signs of autonomic nerve dysfunction (e.g., a decreased production of tears and sweat, and an increased production of saliva). Signs of the distal esophageal spasm were visible in upper gastrointestinal radiography, endoscopy, and high-resolution esophageal manometry. After the POEM, the patient exhibited improvements in nausea and vomiting, and his dysphagia symptoms were relieved by the 6-month follow-up visit. However, the patient's neurological problems persisted. The satisfactory short-term clinical responses in our patient suggest that POEM is feasible, safe, and effective for the treatment of acute pandysautonomia-associated distal esophageal spasms in children.

Abstract
Chicago Classification version 4.0 (CC v4.0), published in 2021, presents several modifications largely aimed at minimizing over-diagnosis of inconclusive patterns on high-resolution manometry (HRM). These include: 1) introduction of a standardized HRM protocol for consistency among centers, 2) emphasis on the need for supportive data in instances of inconclusive manometric patterns, 3) required presence of relevant symptoms in certain instances to reduce over-diagnosis and inappropriate interventions, and 4) classification as disorders of EGJ outflow or disorders of peristalsis. These updates aim to improve the clinical application of HRM and patient outcomes.

Abstract
Distal esophageal spasm (DES) is a motility disorder characterized by premature contraction of the esophageal body during single swallows. It is thought to be due to impairment of esophageal inhibitory pathways, but studies to support this are limited. The normal response to multiple rapid swallows (MRS) is deglutitive inhibition of the esophageal body during the MRS sequence. Our aim was to compare the response to MRS in DES patients and healthy control subjects. Response to MRS during HRM was evaluated in 19 DES patients (8 with and 11 without concomitant esophagogastric junction outflow obstruction [EGJOO]) and 24 asymptomatic healthy controls. Patients with prior gastroesophageal surgery, peroral endoscopic myotomy, pneumatic dilation, esophageal botulinum toxin injection within 6 months of HRM, opioid medication use, and esophageal stricture were excluded. Response to MRS was evaluated for complete versus impaired inhibition (esophageal body contractility with distal contractile integral [DCI] > 100 mmHg-sec-cm during MRS), presence of post-MRS contraction augmentation (DCI post MRS greater than single swallow mean DCI), and integrated relaxation pressure (IRP). Impaired deglutitive inhibition during MRS was significantly more frequent in DES compared to controls (89% vs. 0%, P < 0.001), and frequency was similar for DES with versus without concomitant EGJOO (100% vs. 82%, P = 0.48). The proportion of subjects with augmentation post MRS was similar for both groups (37% vs. 38%, P = 1.00), but mean DCI post MRS was higher in DES than controls (3360.0 vs. 1238.9, P = 0.009). IRP was lower during MRS compared to single swallows in all patients, and IRP during MRS was normal in 5 of 8 patients with DES and EGJOO. Our study suggests that impaired deglutitive inhibition during MRS is present in the majority of patients with DES regardless of whether they have concomitant EGJOO, and future studies should explore the usefulness of incorporating response to MRS in the diagnosis of DES.

Abstract
Diffuse esophageal spasm, also known as distal esophageal spasm (DES), is a rare motility disorder among the population with symptomatic motility disorders. This disorder is most commonly reported in females, with a median age of 60 years. Multiple therapeutic options have been developed for the treatment of DES. There has been limited research regarding the use of peppermint oil in the treatment of DES. Here, we discuss the interesting case of an elderly female patient who received symptomatic relief from peppermint oil.

Abstract
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.

Abstract
OBJECTIVE Distal esophageal spasm (DES) is a rare motility disorder characterized by premature and rapidly propagated contractions of the distal esophagus. Treatment options are limited and often poorly effective. Peroral endoscopic myotomy (POEM) seems an effective and attractive new treatment option for DES. In this case report we describe some of the difficulties that could arise. MATERIALS AND METHODS A 84-year old man with therapy-refractory DES and complaints of severe dysphagia and chest pain underwent a POEM procedure under general anesthesia. A longer myotomy was performed to cleave the circular muscle layer from start till end of the spastic contractions. RESULTS The length of the myotomy was 16 cm. Hyperactive spastic contractions during the procedure complicated the creation of the submucosal tunnel, extended the duration (134 vs. 60-90 min for achalasia), increased postoperative pain and prolonged hospital admission. Intravenously nitroglycerin peroperative diminished spastic contractions. Postoperative a remnant of spastic contractions was present, proximal to the myotomy, causing persistent symptoms. CONCLUSION Performing POEM for DES is challenging due to reactive hyperactive spastic contractions during the procedure causing technical difficulties and an extended procedure. A long myotomy, several centimeters above the proximal border of the spastic region, is essential to prevent remnants of spasticity.

Abstract
In achalasia and spastic esophageal motility disorders, botulinum toxin (botox) injection is considered an effective and low-risk procedure for short-term symptom relief. It is mainly offered to medically high-risk patients. However, no analysis of risks of botox injections has been performed. To determine the incidence and risk factors of procedure-related complications after esophageal botox injections, we analyzed the records of all patients undergoing botox injection therapy for esophageal motility disorders at four university hospitals in Europe and North America between 2008 and 2014. Complications were assigned grades according to the Clavien-Dindo classification. In 386 patients, 661 botox treatments were performed. Main indications were achalasia (51%) and distal esophageal spasm (DES) (30%). In total, 52 (7.9%) mild complications (Clavien-Dindo grade I) were reported by 48 patients, the majority consisting of chest pain or heartburn (29 procedures) or epigastric pain (5 procedures). No ulceration, perforation, pneumothorax, or abscess were reported. One patient died after developing acute mediastinitis (Clavien-Dindo grade V) following injections in the body of the esophagus. In univariate logistic regression, younger age was associated with an increased risk of complications (OR 1.43, 95%CI 1.03-1.96). Treatment for DES, injections into the esophageal body, more injections per procedure, more previous treatments and larger amount of injected botulinum toxin were no risk factors for complications. Esophageal botox injection seems particularly appropriate for high-risk patients due to low complication rate. However, it should not be considered completely safe, as it is associated with rare side effects that cannot be predicted.

Abstract
High-resolution manometry (HRM) is currently the most important diagnostic test for esophageal motility disorders, providing information on the contraction pattern of the circular muscle layer, which helps classify these esophageal motor diseases. However, with the increasing development of ultrasound, other techniques, such as high-frequency intraluminal ultrasound (HFIUS), have gained importance. This technique uses a flexible shaft with a central wire integrated into a standard endoscope, which facilitates real-time sonography. Its main utility is to provide anatomical information on the structure of the esophageal wall, including both the circular and longitudinal layers that constitute the esophageal muscularis propria. Increasing knowledge about these motility disorders has led to the hypothesis that, in addition to an abnormal contraction pattern of the circular muscle, an overall increased muscle thickness and an abnormal longitudinal muscle contraction could be added as pathophysiological factors. The increase in muscle thickness could be an important indicator of the severity of diseases, such as achalasia, distal esophageal spasm, or hypercontractile esophagus. More studies are required before definitive conclusions can be reached, but HFIUS employed simultaneously with HRM could provide a more complete and precise evaluation of these esophageal motor disorders.

Abstract
BACKGROUND In the past, ambulatory 24-h manometry has been shown useful for the evaluation of patients with non-cardiac chest pain (NCCP). With the diagnostic improvements brought by pH-impedance monitoring and high-resolution manometry (HRM), the contribution of ambulatory 24-h manometry to the diagnosis of esophageal hypertensive disorders has become uncertain. Our aim was to assess the additional diagnostic yield of ambulatory manometry to HRM and ambulatory pH-impedance monitoring in this patient population. METHODS All patients underwent 24-h ambulatory pressure-pH-impedance monitoring and HRM. Patients had retrosternal pain as a predominant symptom and no explanation after cardiologic and digestive endoscopic evaluations. Diagnostic measurements were analyzed by two independent physicians. KEY RESULTS Fifty-nine patients met the inclusion criteria; 37.3% of the patients had their symptoms explained by abnormalities on pH-impedance monitoring and 6.8% by ambulatory manometry. Functional chest pain was diagnosed in 52.5% of the patients. High-resolution manometry, using the Chicago Classification v3.0 criteria alone, did not identify any of the four patients with esophageal spasm on ambulatory manometry. However, taking into account other abnormalities, such as simultaneous (rapid) or repetitive contractions, HRM had a sensitivity of 75% and a specificity of 98.2% for the diagnosis of esophageal spasm. CONCLUSIONS & INFERENCES In the work-up of NCCP, ambulatory 24-h manometry has a low additional diagnostic yield. However, it remains the best technique to identify esophageal spasm as the cause of symptoms. This is particularly useful when an unequivocal diagnosis is needed before treatment.

Abstract
Exciting new developments-pharmacologic, endoscopic, and surgical-have arisen for the treatment of many esophageal diseases. Refractory gastroesophageal reflux disease presents a therapeutic challenge, and several new options have been proposed to overcome an insufficient effectiveness of proton pump inhibitors. In patients with distal esophageal spasm, drugs and endoscopic treatments are the current mainstays of the therapeutic approach. Treatment with proton pump inhibitors (or antireflux surgery) should be considered in patients with Barrett's esophagus, since a recent meta-analysis demonstrated a 71% reduction in risk of neoplastic progression. Endoscopic resection combined with radiofrequency ablation is the standard of care in patients with early esophageal adenocarcinoma. Mucosal squamous cancer may also be treated endoscopically, preferably with endoscopic submucosal dissection. Patients with upper esophageal cancer often refrain from surgery. Robot-assisted, thoracolaparoscopic, minimally invasive esophagectomy may be an appropriate option for these patients, as the robot facilitates a good overview of the upper mediastinum. Induction chemoradiotherapy is currently considered as standard treatment for patients with advanced squamous cell carcinoma, while the role of neoadjuvant therapy for adenocarcinoma remains controversial. A system for defining and recording perioperative complications associated with esophagectomy has been recently developed and may help to find predictors of mortality and morbidity.

Abstract
Nutcracker esophagus (NE), Jackhammer esophagus (JHE), distal esophageal spasm (DES), and hypertensive lower esophageal sphincter (HTLES) are defined by esophageal manometric findings. Some patients with these esophageal motility disorders also have abnormal gastroesophageal reflux. It is unclear to what extent these patients' symptoms are caused by the motility disorder, the acid reflux, or both. The aim of this study was to determine the effectiveness of laparoscopic Nissen fundoplication (LNF) on esophageal motility disorders, gastroesophageal reflux, and patient symptoms. Between 2007 and 2013, we performed high-resolution esophageal manometry on 3400 patients, and 221 patients were found to have a spastic esophageal motility disorder. The medical records of these patients were reviewed to determine the manometric abnormality, presence of gastroesophageal symptoms, and amount of esophageal acid exposure. In those patients that underwent LNF, we compared pre- and postoperative esophageal motility, gastroesophageal symptom severity, and esophageal acid exposure. Of the 221 patients with spastic motility disorders, 77 had NE, 2 had JHE, 30 had DES, and 112 had HTLES. The most frequently reported primary and secondary symptoms among all patients were: heartburn and/or regurgitation, 69.2%; respiratory, 39.8%; dysphagia, 35.7%; and chest pain, 22.6%. Of the 221 patients, 192 underwent 24-hour pH monitoring, and 103 demonstrated abnormal distal esophageal acid exposure. Abnormal 24-hour pH monitoring was detected in 62% of patients with heartburn and regurgitation, 49% of patients with respiratory symptoms, 36.8 % of patients with dysphagia, and 32.6% of patients with chest pain. Sixty-six of the 103 patients with abnormal 24-hour pH monitoring underwent LNF. Thirty-eight (13NE, 2JHE, 6 DES, and 17 HTLES) of these 66 patients had a minimum of 6-month postoperative follow-up that included clinical evaluation, esophageal manometry, and 24-hour pH monitoring. Postoperatively, all 38 patients had normal distal esophageal acid exposure. Of these 38 patients, symptoms resolved in 28 and improved in 10. Of six patients (one with NE, two JHE, and three with HTLES) that underwent postoperative esophageal manometry, five exhibited normal motility. Typical reflux symptoms are common among patients with esophageal hypermotility disorders. Abnormal 24-hour pH monitoring is present in the majority of patients with who report typical reflux symptoms and almost half of patients who report respiratory symptoms. Conversely, the majority of patients who report dysphagia or chest pain have normal distal esophageal acid exposure. Based on a small number of patients in this study, it also appears that motility disorders often improve after LNF. LNF is associated with resolution or improvement in reflux related symptoms and esophageal motility parameters in patients exhibiting abnormal esophageal acid exposure. This suggests that patient symptoms are due to abnormal acid exposure and not the motility disorder.

Abstract
BACKGROUND According to the Chicago classification of esophageal motility disorders, distal esophageal spasm (DES) is defined as premature esophageal contractions (distal latency [DL] <4.5 s) for ≥20% of swallows, in the presence of a normal mean integral relaxation pressure (IRP). However, some patients with symptoms of DES have rapid contractions with a normal DL. The aim of this study was to characterize these patients and compare their clinical characteristics to those of patients classified as DES. METHODS We retrospectively compared clinical characteristics and high-resolution manometry findings of patients with rapid contractions with normal latency to those meeting the Chicago classification criteria for DES. KEY RESULTS Over a 3-year period, nine patients were diagnosed with DES and 14 showed rapid contractions in the distal esophagus with normal latency. The latter were younger than DES patients (60 ± 4 vs 72 ± 3 years, p < 0.05). Dysphagia and retrosternal pain occurred to a similar degree in both groups. Weight loss and abnormal barium esophagogram tended to be more frequent in DES patients. There was no difference in contractile front velocity (CFV) and in distal contractile integral (DCI) between patients with DES and rapid contractions with normal latency. Lower esophageal sphincter pressures were not different between groups. However, IRP was significantly higher in DES compared to rapid contractions with normal latency (11.7 ± 0.6 mmHg vs 7.6 ± 1.2 mmHg, p < 0.05), albeit still within the normal range. CONCLUSIONS & INFERENCES These data suggest that patients with simultaneous contractions with normal latency represent a group of patients with many features similar to DES.

Abstract
Endoscopic injections of botulinum toxin in the cardia or distal esophagus have been advocated to treat achalasia and spastic esophageal motility disorders. We conducted a retrospective study to evaluate whether manometric diagnosis using the Chicago classification in high-resolution manometry (HRM) would be predictive of the clinical response. Charts of patients with spastic and hypertensive motility disorders diagnosed with HRM and treated with botulinum toxin were retrospectively reviewed at two centers. HRM recordings were systematically reanalyzed, and a patient's phone survey was conducted. Forty-five patients treated between 2008 and 2013 were included. Most patients had achalasia type 3 (22 cases). Other diagnoses were jackhammer esophagus (8 cases), distal esophageal spasm (7 cases), esophagogastric junction outflow obstruction (5 cases), nutcracker esophagus (1 case), and 2 unclassified cases. Botulinum toxin injections were performed into the cardia only in 9 cases, into the wall of the distal esophagus in 19 cases, and in both locations (cardia and distal esophagus) in 17 cases. No complication occurred in 31 cases. Chest pain was noticed for less than 7 days in 13 cases. One death related to mediastinitis occurred 3 weeks after botulinum toxin injection. Efficacy was assessed in 42 patients: 71% were significantly improved 2 months after botulinum toxin, and 57% remained satisfied for more than 6 months. No clear difference was observed in terms of response according to manometric diagnosis; however, type 3 achalasia previously dilated and with normal integrated relaxation pressure (4s-integrated relaxation pressure < 15 mmHg) had the worst outcome: none of these patients responded to the endoscopic injection of botulinum toxin. Endoscopic injections of botulinum toxin may be effective in some patients with spastic or hypercontractile esophageal motility disorders. The manometric Chicago classification diagnosis does not seem to predict the results. Prospective randomized trials are required to identify patients most likely to benefit from esophageal botulinum toxin treatment.

Abstract
Although conventional manometry set the basis for the diagnosis of esophageal motility disorders, the large axial spacing between recording sites leaves large portions of the esophagus unevaluated and vulnerable to movement artifact. However, continuous spatiotemporal representations of pressure through the esophagus recorded with high-resolution manometry offers greater detail and improved accuracy for many of the most important measurements of esophageal motor function. This review describes how the new classification schemes for esophageal pressure topography have evolved from conventional criteria and focuses on how esophageal pressure topography has improved the ability to subcategorize conventional manometric diagnoses into new functional phenotypes.

Abstract
The concept of esophageal spastic disorders encompasses spastic achalasia, distal esophageal spasm, and jackhammer esophagus. These are conceptually distinct in that spastic achalasia and distal esophageal spasm are characterized by a loss of neural inhibition, whereas jackhammer esophagus is associated with hypercontractility. Hypercontractility may also occur as a result of esophagogastric junction outflow obstruction or inflammation. The diagnosis of jackhammer esophagus as a primary motility disorder is based on the characteristic manometric findings after ruling out mechanical obstruction and eosinophilic esophagitis. Despite the differences in pathophysiology among the esophageal spastic disorders, their management is similar.

Abstract
BACKGROUND The contractile deceleration point (CDP) is an important landmark for interpreting esophageal pressure topography (EPT) plots. Previous analysis in normal subjects confirmed that the CDP could be localized using an algorithm that found the time during peristalsis at which a maximal length of the distal esophagus was contracting concurrently (tML method). This study aimed to test the tML method for localizing CDP in patients with abnormal motility. METHODS High-resolution manometry studies of 75 patients with normal and disordered peristalsis were analyzed. Two experts, JEP and YX, used the original tangent-intersection method to score CDP coordinates for the first two swallows of each study. Alternative computerized algorithms tested against the expert were: (i) the tML method, (ii & iii) the intercept between the leading edge of the 30-mmHg isobaric contour and a line 2.0 cm (or 10% of esophageal length) proximal to the esophagogastric junction (EGJ) at rest, or (iv) the 'tML-3 cm' method, which added the stipulation that the CDP be within 3 cm of the EGJ. KEY RESULTS All tested algorithms were highly correlated with the expert. However, the tMl-3 cm method was better in the sense that it eliminated outliers (>1 s discrepancy with the expert) that occurred with the other methods usually attributable to weak distal peristalsis. CONCLUSIONS & INFERENCES Optimal automated CDP localization was achieved in both normal and a spectrum of abnormal motility using the tML method with the added stipulation that the CDP be restricted to within the distal 3 cm of the EGJ at rest.

Abstract
PURPOSE OF REVIEW The Chicago Classification for esophageal motility disorders was developed to complement the enhanced characterization of esophageal motility provided by high-resolution esophageal pressure topography (HREPT) as this new technology has emerged within clinical practice. This review aims to summarize the evidence supporting the evolution of the classification scheme since its inception. RECENT FINDINGS Studies examining the specific esophageal motility disorders in regards to HREPT metrics, clinical characteristics, and responses to treatments have facilitated updates of the diagnostic scheme and criteria. These studies have demonstrated variation in treatment responses associated with subclassification of achalasia, the use of distal latency in the diagnosis of distal esophageal spasm, and the development of diagnoses including esophagogastric junction outflow obstruction and hypercontractile esophagus. SUMMARY The diagnostic criteria described in the Chicago Classification have evolved to demonstrate a greater focus on distinct clinical phenotypes. Future evaluation of the natural history and treatment outcomes will assist in further refinement of this diagnostic scheme and management of esophageal motility disorders.

Abstract
BACKGROUND The manometric diagnosis of distal esophageal spasm (DES) uses "simultaneous contractions" as a defining criterion, ignoring the concept of short latency distal contractions as an important feature. Our aim was to apply standardized metrics of contraction velocity and latency to high-resolution esophageal pressure topography (EPT) studies to refine the diagnosis of DES. METHODS Two thousand consecutive EPT studies were analyzed for contractile front velocity (CFV) and distal latency to identify patients potentially having DES. Normal limits for CFV and distal latency were established from 75 control subjects. Clinical data of patients with reduced distal latency and/or rapid CFV were reviewed. RESULTS Of 1070 evaluable patients, 91 (8.5%) had a high CFV and/or low distal latency. Patients with only rapid contractions (n = 186 [17.4%] using conventional manometry criteria; n = 85 [7.9%] using EPT criteria) were heterogeneous in diagnosis and symptoms, with the majority ultimately categorized as weak peristalsis or normal. In contrast, 96% of patients with premature contraction had dysphagia, and all (n = 24; 2.2% overall) were ultimately managed as spastic achalasia or DES. CONCLUSIONS The current DES diagnostic paradigm focused on "simultaneous contractions" identifies a large heterogeneous set of patients, most of whom do not have a clinical syndrome suggestive of esophageal spasm. Incorporating distal latency into the diagnostic algorithm of EPT studies improves upon this by isolating disorders of homogeneous pathophysiology: DES with short latency and spastic achalasia. We hypothesize that prioritizing measurement of distal latency will refine the management of these disorders, recognizing that outcomes trials are necessary.

Abstract
Two recent advances have revolutionized the performance of clinical esophageal manometry; the introduction of practical high resolution manometry (HRM) systems and the development of sophisticated algorithms to display the expanded manometric dataset as pressure topography plots. We utilized a large clinical experience of 400 consecutive patients and 75 control subjects to develop a systematic approach to analyzing esophageal motility using HRM and pressure topography plots. The resultant classification scheme has been named as the Chicago Classification of esophageal motility. Two strengths of pressure topography plots compared with conventional manometric recordings were the ability to (1) delineate the spatial limits, vigor, and integrity of individual contractile segments along the esophagus and (2) to distinguish between loci of compartmentalized intraesophageal pressurization and rapidly propagated contractions. Making these distinctions objectified the identification of distal esophageal spasm, vigorous achalasia, functional obstruction, and nutcracker esophagus subtypes. Applying these distinctions made the diagnosis of spastic disorders quite rare: spasm in 1.5% of patients, vigorous achalasia in 1.5%, and a newly defined entity, spastic nutcracker, in 1.5%. Ultimately, further clinical experience will be the judge, but it is our expectation that pressure topography analysis of HRM data, along with its well-defined functional implications, will prove valuable in the clinical management of esophageal motility disorders.
