Abstract
Jackhammer esophagus (JE) is a recently recognized esophageal motility disorder that is characterized by hypercontractile peristalsis. More than 500 cases have been reported in the literature. Among patients referred for esophageal motility disorders, the prevalence of JE ranges from 0.42% to 9%, with most series describing a prevalence of 2% to 4%. Most cases are women (60.5%). The mean reported age of patients with JE is 65.2 years, and patients commonly have dysphagia (62.8%). Reflux symptoms occur in ∼40% of patients, and chest pain affects more than one-third of patients (36.4%). JE is a heterogenous disorder that is associated with several conditions, including obesity, opioid use, lung transplantation, eosinophilic infiltration of the esophagus, neoplasia, and systemic diseases. The cause and pathogenesis remain unknown, but several observations suggest that it is the result of multiple conditions that likely precipitate increased excitation and abnormal inhibition of neuromuscular function. The natural course of JE also is unknown, but progression to achalasia has been observed in a few patients. Treatment is challenging, in part because of the insufficient understanding of the disorder's underlying mechanisms. Various therapeutic modalities have been used, ranging from observation only to pharmacologic and endoscopic interventions (eg, botulinum toxin injection) to peroral endoscopic myotomy. Treatment efficacy remains largely anecdotal and insufficiently studied.

Abstract
BACKGROUND Jackhammer esophagus (JE) is a newly described esophageal motility disorder. However, there are limited data on JE and this entity remains misunderstood. METHODS We performed a systematic review of clinical series on JE through MEDLINE, EMBASE, and Web of Science. Data from included studies were then extracted, and random-effects meta-analyses were performed. RESULTS Thirty-eight studies met inclusion criteria. The pooled prevalence of JE was 1.97% [95% CI: 1.39%-2.78%] among patients referred for high-resolution manometry (HRM). The mean age at diagnosis was 60.8 years [95% CI: 57.1-64.4] and 65% [95% CI: 58%-72%] of patients were female. JE was significantly more prevalent in postlung transplant patients and morbidly obese patients undergoing HRM (23.99% [95% CI: 9.00%-38.97%] and 5.18% [95% CI: 1.76%-14.3%] respectively). Dysphagia was the most common presentation of JE (64% [95% CI: 52%-77%]) followed by gastroesophageal reflux disease (46% [95% CI: 26%-67%]). The pooled mean distal contractile integral (DCI) of all standard HRM swallows was 9249 mm Hg·s·cm [95% CI: 7834-10 663], and the pooled mean integrated relaxation pressure (IRP) was 13.9 mm Hg [95% CI: 8.2-19.7]. Overall, 73.6% [95% CI: 64.0%-83.1%] of JE patients who underwent treatment achieved clinical symptom improvement (79% [95% CI: 74%-85%] for endoscopic treatment and 63% [95% CI: 47%-79%] for medical treatment). The pooled clinical success rate of peroral endoscopic myotomy (POEM) specifically was 82% [95% CI: 75%-90%]. CONCLUSIONS JE is a new motility disorder most commonly presenting with dysphagia. High clinical suspicion is important because the diagnosis can only be made through HRM.

Abstract
GOALS The aim of our study was to characterize jackhammer esophagus symptoms and their relationship with the distal contractile integral (DCI) and bolus transit. BACKGROUND Jackhammer esophagus is defined by the Chicago Classification version 3.0. This diagnosis is relatively new, with the most current definition being established in 2014. The forerunners of this diagnosis, nutcracker (or hypercontractile) esophagus, have been associated with noncardiac chest pain (NCCP). STUDY A retrospective chart review was performed of motility studies from 2011 to 2016. Studies with a diagnosis of jackhammer esophagus, hypercontractile esophagus, nutcracker, esophagogastric junction outflow obstruction, or hypertensive lower esophageal sphincter were reread using Chicago Classification version 3.0, and were included if they met criteria for jackhammer esophagus. Unpaired t-tests were used for analysis (P≤0.05). RESULTS In total, 142 studies were identified with the above diagnoses. After excluding 84 studies, 58 remained for analysis and 17 were found to have jackhammer esophagus (29%). The mean age was 54 (28 to 75), 5 (29%) were males and 12 (71%) were females. The primary indications were NCCP (5), dysphagia (8), and other causes (4) (cough, heartburn, or regurgitation). The mean DCIs were 17,245 mm Hg×s×cm (NCCP), 14,669 mm Hg×s×cm (dysphagia), and 11,264 mm Hg×s×cm (other causes). The mean DCIs were compared: NCCP versus dysphagia (P=0.41), and NCCP versus other causes (P=0.05). Fifteen (88%) had normal bolus transit for both liquid and viscous swallows. CONCLUSIONS In our small sample size, dysphagia was frequently the presenting symptom followed by NCCP. Those with NCCP have a trend toward a higher DCI. Bolus transit appeared to be normal in this patient population. More data are needed to further elucidate the genesis of symptoms and how they relate to the degree of contractility.

The clinical significance of hypercontractile peristalsis: comparison of high-resolution manometric features, demographics, symptom presentation, and response to therapy in patients with Jackhammer esophagus versus Nutcracker esophagus. Dis Esophagus 2017; 30:1-7.

Abstract
The Chicago Classification version 3.0 (CC v 3.0) defines hypercontractile peristalsis as Jackhammer esophagus (JE); Nutcracker esophagus (NE) is no longer recognized. Data regarding patient characteristics and treatment response for JE versus NE are limited. We aimed to compare demographic characteristics, high resolution manometry (HRM) features, clinical presentation, management strategies, and treatment outcomes in patients with JE versus NE. We performed a retrospective analysis of adult patients diagnosed with NE (CC v 2.0) or JE (CC v 3.0) by HRM from January 2012 to August 2015. Demographics, symptoms, treatments, and response to therapy (none or partial/complete) were ascertained by chart review, for statistical comparisons. In 45 patients with JE and 29 with NE, there was no significant difference in rate of dysphagia (73% and 59%) or chest pain (44% and 59%). Treatment data were available in 29 JE (smooth muscle relaxants in 4, pain modulators in 3, botulinum toxin injection (BTX) in 10, endoscopic dilation in 5, multimodal treatment in 7), and 20 NE patients (smooth muscle relaxants in 2, pain modulators in 2, (BTX) in 6, endoscopic dilation in 3, multimodal treatment in 7). Follow-up data on 26/29 JE and 20/20 NE patients showed similar treatment response (96.4% vs. 82.1%, p= 0.08) after mean follow-up of 11.2 and 11 months, respectively. There were no major differences for JE versus NE in demographics, symptoms, or type of and response to therapy. Larger prospective, controlled trials are needed to clarify the clinical significance and response to treatment in JE and NE.

Abstract
BACKGROUND An association between acid gastro-oesophageal reflux disease (GERD) and Jackhammer oesophagus has been suggested. AIM To assess the prevalence and characteristics of acid-GERD in Jackhammer oesophagus and the efficacy of proton pump inhibitors. METHODS Data and outcomes of patients with Jackhammer oesophagus were assessed. Two groups were compared: (i) GERD, defined by endoscopic oesophagitis or by an increase in acid exposure time or by an acid-hypersensitive oesophagus and (ii) non-GERD defined by normal oesophageal acid exposure without acid-hypersensitive oesophagus. RESULTS Among the 1994 high-resolution manometries performed, 44 Jackhammer oesophagus (2.2%) were included (sex ratio M/F: 19/25; median age: 66 [61-75] years). Nineteen patients (43.2%) had GERD, 16 (36.4%) had no GERD and 9 patients (20.4%) were undetermined. Dysphagia was the predominant symptom (37/43 (86%)). After a median follow-up of 25.3 months [9.6-31.4], dysphagia was improved in 22/36 (61.1%) patients. Dysphagia improvement as well as other symptoms improvement was not associated with GERD status or proton-pump inhibitors use. CONCLUSION The prevalence of GERD is high among patients with Jackhammer oesophagus. The rates of symptom improvement in Jackhammer oesophagus were high regardless of the use of proton-pump inhibitors treatment or of the presence of GERD.

Abstract
The clinical significance of lymphocytic esophagitis (LyE), which is characterized by the prominence of peripapillary intraepithelial lymphocytes (IELs) without significant granulocytosis, remains poorly understood. During the last few years, plausible clinical correlates and novel approaches for stratification of LyE have started to emerge. Association with Crohn's disease has been established in children, but is not observed in adults. In adults, the form of LyE showing CD4+ -predominant IELs has been recently found to be associated with non-achalasia primary motility abnormalities. GERD is another possible association. The most common clinical manifestations of adult LyE are dysphagia and normal endoscopic appearance of the esophagus. LyE should be reported by pathologists in order to distinguish it from its mimics, such as eosinophilic esophagitis, and to assist in directing the next steps in evaluation for known associated diseases, such as Crohn's disease or motility disorders.

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 & AIMS High-resolution manometry (HRM) expands recognition of minor esophageal motor abnormalities, but the clinical significance of these is unclear. We aimed to determine the outcomes of minor esophageal motor abnormalities. METHODS We reviewed HRM tracings from patients who underwent esophageal manometry at Northwestern Memorial Hospital from July 2004 through October 2005 by using the Chicago classification (version 2.0). We identified 301 patients with normal findings or minor manometric abnormalities (weak peristalsis, hypertensive peristalsis, frequent failed peristalsis, or rapid contractions with normal latency). Ninety-eight patients participated in a phone survey in which they were asked questions from the impact dysphagia questionnaire (mean follow-up period, 6 years 5 months). RESULTS Of 301 patients assessed, 166 had normal findings from HRM, 82 had weak peristalsis, 34 had hypertensive peristalsis, 17 had frequent failed peristalsis, and 2 had rapid contractions with normal latency. The primary indications for HRM of dysphagia (44%) and gastroesophageal reflux disease (63%) were unrelated to manometric findings. There were no endoscopic or videofluoroscopic differences between patients with minor manometric abnormalities. Of 98 patients with follow-up, findings from HRM were normal in 63, weak peristalsis was observed in 23, hypertensive peristalsis was observed in 10, and frequent failed peristalsis was observed in 2. No patients underwent surgical myotomy, pneumatic dilation, or botulinum toxin injection. Use of proton pump inhibitors and rates of fundoplication were similar, regardless of manometric findings. Sixteen patients (16%) had significant dysphagia at follow-up; hypertensive peristalsis was the most likely to be symptomatic. CONCLUSIONS Patients with normal and minor esophageal motor abnormalities report minimal symptoms and have few medical interventions related to esophageal dysfunction during long-term follow-up. Therefore, identification of normal and minor motor function is likely a good prognostic indicator.

Abstract
Fibromyalgia is a disorder characterized by an abnormal pain regulation. Widespread pain, fatigue, and sleep disturbance are the prevalent symptoms. When unusual symptoms are overbearingly predominant at clinical presentation, the diagnosis becomes challenging.We report on the case of a patient with fibromyalgia, who presented with dysphagia, odynophagia, and glossodynia as prevalent symptoms. Difficulty in swallowing gradually developed over a month prior hospitalization, and worsened progressively so that nourishment and fluid intake were impeded.Because anemia with mild iron deficiency was found, esophagogastroduodenoscopy was performed, but no lesions were seen in the upper digestive tract. Levels of zinc and vitamin B12 were normal. Intense pain at pelvis and the inferior limbs, which was at a first glance referred to as osteoarthrosis, associated with oral symptoms and feeling of being in the clouds allowed us to diagnose fibromyalgia. Amitriptyline was used, with relief of symptoms.Although oropharyngeal symptoms were occasionally reported in fibromyalgia, they are often overlooked. The present case, therefore, testifies the need to consider the diagnosis of fibromyalgia when the patient presents with such symptoms that cannot be readily explained on other grounds.

Abstract
With the development of high-resolution manometry and specific metrics to characterize esophageal motility, the Chicago Classification has become the gold standard for the diagnosis of esophageal motor disorders. Major and significant disorders, that is, never observed in healthy subjects, are achalasia, esophagogastric junction outflow obstruction, distal esophageal spasm, absent peristalsis, and hypercontractile (Jackhammer) esophagus. Achalasia subtyping is relevant to predict the response to endoscopic and surgical therapies as several studies suggest that, pneumatic dilation is less effective than Heller myotomy, in type III achalasia. Peroral endoscopic myotomy, initially developed in expert centers, is a promising technique for the treatment of achalasia. The medical therapeutic options for distal esophageal spasm and hypercontractile esophagus are smooth muscle relaxants and pain modulators. Intraesophageal injection of botulinum toxin might be an interesting option for treatment of these disorders but further studies are required to determine the optimal injection protocol and the best candidates based on manometric patterns. The treatment of hypotensive motility disorders is disappointing and relies mainly on dietary and lifestyle changes as no effective esophageal prokinetic is currently available.

Abstract
Esophageal hypomotility (EH) is characterized by abnormal esophageal peristalsis, either from a reduction or absence of contractions, whereas spastic motor disorders (SMD) are characterized by an increase in the vigor and/or propagation velocity of esophageal body contractions. Their pathophysiology is not clearly known. The reduced excitation of the smooth muscle contraction mediated by cholinergic neurons and the impairment of inhibitory ganglion neuronal function mediated by nitric oxide are likely mechanisms of the peristaltic abnormalities seen in EH and SMD, respectively. Dysphagia and chest pain are the most frequent clinical manifestations for both of these dysfunctions, and gastroesophageal reflux disease (GERD) is commonly associated with these motor disorders. The introduction of high-resolution manometry (HRM) and esophageal pressure topography (EPT) has significantly enhanced the ability to diagnose EH and SMD. Novel EPT metrics in particular the development of the Chicago Classification of esophageal motor disorders has enabled improved characterization of these abnormalities. The first step in the management of EH and SMD is to treat GERD, especially when esophageal testing shows pathologic reflux. Smooth muscle relaxants (nitrates, calcium channel blockers, 5-phosphodiesterase inhibitors) and pain modulators may be useful in the management of dysphagia or pain in SMD. Endoscopic Botox injection and pneumatic dilation are the second-line therapies. Extended myotomy of the esophageal body or peroral endoscopic myotomy (POEM) may be considered in highly selected cases but lack evidence.
