BACKGROUND: The aim of this study was to investigate whether any esophageal motor dysfunction exists in patients with iron deficiency anemia (IDA). METHODS: The study included 39 patients (34 women, mean age: 44.17 ± 14.21 years) who met WHO diagnostic criteria for IDA. An additional 30 functional dyspepsia patients were also included as a control group. Esophageal motility testing was performed; esophagus contraction amplitude, peak velocity, contraction time, lower esophageal sphincter (LES) resting pressure, LES relaxation, and LES relaxation duration were assessed...

BACKGROUND/AIMS: Per-oral endoscopic myotomy (POEM) is a new minimally invasive technique to treat achalasia. METHODS: We performed a review of the literature of POEM with a special focus on technical details and the results obtained with this technique in patients with achalasia and other esophageal motility disorders. RESULTS: Thousands of POEM procedures have been performed worldwide since its introduction in 2008. The procedure is based on the creation of a mucosal entry point in the proximal esophagus to reach the cardia through a submucosal tunnel and then perform a myotomy of the muscular layers of the cardia, esophagogastric junction and distal esophagus, as performed in a Heller myotomy...

Infants and children with esophageal atresia commonly present with swallowing dysfunction or dysphagia. Dysphagia can lead to a range of significant consequences such as aspiration pneumonia, malnutrition, dehydration, and food impaction. To improve oral intake, the clinical diagnosis of dysphagia in patients with esophageal atresia should focus on both the pharynx and the esophagus. To characterize the complex interactions of bolus flow and motor function between mouth, pharynx, and esophagus, a detailed understanding of normal and abnormal deglutition is required through the use of adequate and objective assessment techniques...

The best-defined primary esophageal motor disorder is achalasia. However, symptoms such as dysphagia, regurgitation and chest pain can be caused by other esophageal motility disorders. The Chicago classification introduced new manometric parameters and better defined esophageal motility disorders. Motility disorders beyond achalasia with the current classification are: esophagogastric junction outflow obstruction, major disorders of peristalsis (distal esophageal spasm, hypercontractile esophagus, absent contractility) and minor disorders of peristalsis (ineffective esophageal motility, fragmented peristalsis)...

INTRODUCTION: Peroral endoscopic myotomy (POEM) has been performed since 2008 on more than 5,000 patients. It has proven to be highly effective in the treatment of achalasia and has shown promising outcomes for other esophageal motility spastic disorders. METHODS: A literature review of the efficacy of POEM compared to the previous invasive treatments for different esophageal motility disorders was performed. The application in the pediatric and elderly populations and its role as a rescue therapy after other procedures are also outlined...

BACKGROUND: Epiphrenic esophageal diverticulum is a rare condition that is often associated with a concomitant esophageal motor disorder. Some patients have the chief complaints of swallowing difficulty and gastroesophageal reflux; traditionally, such diverticula have been resected via right thoracotomy. Here, we describe a case with huge multiple epiphrenic diverticula with motility disorder, which were successfully resected using a video-assisted thoracic and laparoscopic procedure...

The best-defined primary esophageal motor disorder is achalasia. However, symptoms such as dysphagia, regurgitation and chest pain can be caused by other esophageal motility disorders such as Diffuse Esophageal Spasm (DES), Nutcracker Esophagus (NE) and the Hypertensive Lower Esophageal Sphincter (HTN-LES). Most patients with DES and HTN-LES who complain of dysphagia improve after a myotomy. Patients with NE whose main complaint is chest pain, often do not have relief of the pain and can even develop dysphagia as a consequence of the myotomy...

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...

Achalasia is a primary esophageal motor disorder of the esophagus that is characterized by the absence of esophageal peristalsis and a failure of the lower esophageal sphincter (LES) to relax upon swallowing. The defective relaxation leads to symptoms of dysphagia for solids and liquids, regurgitation, aspiration, chest pain, and weight loss. Achalasia is believed to result from a selective loss of enteric inhibitory neurons, most likely due to an autoimmune phenomenon in genetic susceptible individuals. As there is no curative treatment for achalasia, treatment is confined to disruption of the LES to improve bolus passage...

BACKGROUND & AIMS: Systemic scleroderma (SSc) is associated with esophageal aperistalsis and hypotensive esophagogastric junction pressure, although there could be a gradation in esophageal motor dysfunction. We characterized esophageal motor function by high-resolution esophageal manometry (HRM) and assessed associations between SSc severity, health-related quality of life (HRQOL), and HRM findings in patients. METHODS: We performed a prospective study of 200 patients with SSc and 102 patients without SSc (controls) who underwent HRM at Mayo Clinic Arizona from May 2006 through January 2015...

A A Sheptulin, I B Belousova
The importance of prokinetics (drugs stimulating motor function of the gastrointestinal tract) arises from the high prevalence of gastroenterological pathology associated with primary or secondary disturbances of this function in esophagus, stomach, and intestines. The main groups of prokinetics are beta-blockers of dopamine receptors, inhibitors of acetylcholine esterase (or their combination with dopamine receptor blockers), 5-HT4-receptor agonists. They find wide application for the treatment of gastroesophgeal reflux disease, functional dyspepsia and constipation, obstipational form of irritable bowel syndrome, and other conditions accompanied by motor function disorders of the gastrointestinal tract...

BACKGROUND: The mechanism of esophageal pain in patients with nutcracker esophagus (NE) and other esophageal motor disorders is not known. Our recent study shows that baseline esophageal mucosal perfusion, measured by laser Doppler perfusion monitoring, is lower in NE patients compared to controls. The goal of our current study was to perform a more detailed analysis of esophageal mucosal blood perfusion (EMBP) waveform of NE patients and controls to determine the optimal EMBP biomarkers that combined with suitable statistical learning models produce robust discrimination between the two groups...

Muscularis propria throughout the entire gastrointestinal tract including the esophagus is comprised of circular and longitudinal muscle layers. Based on the studies conducted in the colon and the small intestine, for more than a century, it has been debated whether the two muscle layers contract synchronously or reciprocally during the ascending contraction and descending relaxation of the peristaltic reflex. Recent studies in the esophagus and colon prove that the two muscle layers indeed contract and relax together in almost perfect synchrony during ascending contraction and descending relaxation of the peristaltic reflex, respectively...

Background/Aims: Esophageal dysmotility is associated with gastrointestinal dysmotility in various systemic and neuroregulatory disorders. Hypothyroidism has been reported to be associated with impaired motor function in esophagus due to accumulation of glycosaminoglycan hyaluronic acid in its soft tissues, leading to changes in various contraction and relaxation parameters of esophagus, particularly in the lower esophageal sphincter. In this study we evaluated esophageal transit times in patients of primary hypothyroidism using the technique of radionuclide esophageal transit scintigraphy...

Recent technological advances in esophageal manometry allowed the definition of new classification methods for the diagnosis of disorders of esophageal motility and the implementation of innovative computational tools for the autonomic, reliable and unbiased detection of different disorders. Computational models can be developed aiming to interpret the mechanical behavior and functionality of the gastrointestinal tract and to summarize the results from clinical measurements, as high-resolution manometry pressure plots, into model parameters...

To understand the abnormalities that underpin functional gut disorders we must first gain insight into the normal patterns of gut motility. While detailed information continually builds on the motor patterns (and mechanisms that control them) of the human esophagus and anorectum, our knowledge of normal and abnormal motility in the more inaccessible regions of the gut remains poor. This particularly true of the human colon. Investigation of in vivo colonic motor patterns is achieved through measures of transit (radiology, scintigraphy and, more recently, "smart pills") or by direct real-time recording of colonic contractility (intraluminal manometry)...

Functional esophageal disorders consist of a disease category that present with esophageal symptoms (heartburn, chest pain, dysphagia, globus) not explained by mechanical obstruction (stricture, tumor, eosinophilic esophagitis), major motor disorders (achalasia, EGJ outflow obstruction, absent contractility, distal esophageal spasm, jackhammer esophagus), or gastroesophageal reflux disease (GERD). While mechanisms responsible are unclear, it is theorized that visceral hypersensitivity and hypervigilance play an important role in symptom generation, in the context of normal or borderline function...

Transient receptor potential (TRP) channels are predominantly distributed in both somatic and visceral sensory nervous systems and play a crucial role in sensory transduction. As the largest visceral organ system, the gastrointestinal (GI) tract frequently accommodates external inputs, which stimulate sensory nerves to initiate and coordinate sensory and motor functions in order to digest and absorb nutrients. Meanwhile, the sensory nerves in the GI tract are also able to detect potential tissue damage by responding to noxious irritants...
