There has been much progress in our understanding of esophageal inflammatory disorders in the past few years. This is particularly true about esophageal eosinophilia and PPI responsiveness, lymphocytic esophagitis and motility disorders, and short-term risk of neoplasia in esophageal leukoplakia. The current review will summarize esophageal injury patterns that primarily occur due to non-reflux causes, with a focus on usual pitfalls in biopsy diagnosis and recent advances in our knowledge of the more common forms of esophagitis...

BACKGROUND: Ineffective esophageal motility (IEM) is the most common finding on high-resolution esophageal manometry (HREM). The underlying mechanisms for IEM remain to be fully elucidated. The aim of this study was to determine if utilization of skeletal muscle relaxants is associated with IEM, and with more severe subtypes of the disorder. METHODS: Patients with diagnosis of IEM were gender and age matched to patients with normal HREM. Demographic information, symptoms, endoscopic findings, medication usage and medical comorbidities were recorded...

BACKGROUND: Achalasia is a primary esophageal motility disorder of unknown etiology associated with abnormalities in peristalsis and lower esophageal sphincter relaxation. The disease is incurable; however, definitive treatment procedures like pneumatic dilation (PD)/balloon dilation and laparoscopic esophageal myotomy (LEM) are performed to relieve dysphagia and related symptoms. Currently, there is paucity of data comparing the outcomes of these procedures. The aim of this meta-analysis is to compare the short- and long-term success rates of PD and LEM...

OBJECTIVE: Degenerative phenomena may affect esophageal motility as a relevant social-health problem. The diagnosis of such disorders is usually performed by the analysis of data from high resolution manometry (HRM). Inter- and intra-observer variability frequently affects the diagnosis, with potential interpretative and thus therapeutic errors, with unnecessary or worse treatments. This may be avoided with automatic procedures that minimize human intervention in data processing. METHODS: In order to support the traditional diagnostic process, an automatic procedure was defined considering a specific physio-mechanical model that is able to objectively interpret data from HRM...

The number and the proportion of older people in the world have both increased substantially in recent years in most countries, and the growth is projected to accelerate in the coming decades. It is thus important to gain a better understanding of the most frequent diseases in people living to advanced old age. Although the aging process has clinically significant effects on oropharyngeal and upper esophageal motility, colonic function and gastrointestinal (GI) immunity, no specific GI disease of the aged population is known...

Gastrointestinal motility disorders are common in the pediatric population and may affect the entire gastrointestinal tract and can vary from mild to severe conditions. They may clinically manifest as gastro-esophageal reflux symptoms, feeding difficulties and failure to thrive, constipation and diarrhea amongst others. This review first highlights the embryologic development of the gastrointestinal tract, after which the prenatal and neonatal development of gastrointestinal motility is discussed. Normal motility patterns as seen in (preterm) infants are described as a background for the discussion of the most common congenital and acquired motility disorders in infancy...

Chronic hyperglycemia is a well-known cause of gastrointestinal motility disorders extending from the esophagus to the anorectum. Even though little attention has been paid to esophageal disorders in the context of DM, its prevalence is higher compared to gastroparesis. Heartburn, as a typical symptom of gastroesophageal reflux disease (GERD), is the most prevalent symptom and has been found in 25 to 41% of patients with DM. Furthermore, DM has recently been established as possible independent factor for the development of Barrett's esophagus...

Achalasia is one of the most studied esophageal motility disorders. However, the pathophysiology and reasons that patients develop achalasia are still unclear. Patients often present with dysphagia to solids and liquids, regurgitation, and varying degrees of weight loss. There is significant latency prior to diagnosis, which can have nutritional implications. The diagnosis is suspected based on clinical history and confirmed by esophageal high-resolution manometry testing. Esophagogastroduodenoscopy is necessary to rule out potential malignancy that can mimic achalasia...

High-resolution manometry is an imaging modality which enables the categorization of esophageal motility disorders. Spatio-temporal pressure data along the esophagus is acquired using a tubular device and multiple test swallows are performed by the patient. Current approaches visualize these swallows as individual instances, despite the fact that aggregated metrics are relevant in the diagnostic process. Based on the current Chicago Classification, which serves as the gold standard in this area, we introduce a visualization supporting an efficient and correct diagnosis...

Currently, the diagnosis of esophageal motility disorders is in part based upon a hierarchical algorithm in which abnormalities of the esophagogastric junction (EGJ) is prioritized. An important metric in evaluating the EGJ is the integrated relaxation pressure (IRP). Patients who do not have achalasia but are found to have an elevated IRP are diagnosed with EGJ outflow obstruction. It has been our observation that a subset of these patients also has a second named motility disorder and may also have abnormal bolus transit...

BACKGROUND: Achalasia is a primary esophageal motility disorder characterized by aperistalsis of the esophagus and failed relaxation of the lower esophageal sphincter that presents rarely in childhood. The peroral endoscopic myotomy (POEM) procedure is an emerging treatment for achalasia in adults that has recently been introduced into pediatric surgical practice. METHODS: This is a prospective case series of all children referred to Stanford University Lucile Packard Children's Hospital with manometry-confirmed achalasia who underwent a POEM procedure from 2014 to 2016...

BACKGROUND: Only a few reports focused on esophageal motility in patients with proton pump inhibitor (PPI)-refractory nonerosive reflux disease (NERD) and there has been no established strategy for treatment. OBJECTIVE: To clarify the characteristics of esophageal motility in patients with PPI-refractory NERD, we evaluated esophageal function using combined multichannel intraluminal impedance and esophageal manometry (MII-EM). In addition, we evaluated the efficacy of rikkunshito (RKT), which is a gastrointestinal prokinetic agent...

Distal esophageal spasm (DES) is a primary esophageal motility disorder. We encountered a rare case of DES accompanied by multiple esophageal diverticula. A 72-year-old woman complained of prolonged dysphagia and chest pain. A barium esophagogram showed multiple esophageal diverticula and significant contraction of the lower esophagus just above the cardia. Esophagogastroduodenoscopy revealed a corkscrew-like appearance, with spiral contractions and diverticula. High-resolution manometry revealed that the integrated relaxation pressure was normal; premature contractions were observed in ≥20% of the swallowing wave; the distal contractile integral was normal...

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...
