Dushant S Uppal, Andrew Y Wang
Achalasia is the most common primary motility disorder of the esophagus and presents as dysphagia to solids and liquids. It is characterized by impaired deglutitive relaxation of the lower esophageal sphincter. High-resolution manometry allows for definitive diagnosis and classification of achalasia, with type II being the most responsive to therapy. Since no cure for achalasia exists, early diagnosis and treatment of the disease is critical to prevent end-stage disease. The central tenant of diagnosis is to first rule out mechanical obstruction due to stricture or malignancy, which is often accomplished by endoscopic and fluoroscopic examination...

OBJECTIVES: Esophagogastric junction (EGJ) distensibility and distension-mediated peristalsis can be assessed with the functional lumen imaging probe (FLIP) during a sedated upper endoscopy. We aimed to describe esophageal motility assessment using FLIP topography in patients presenting with dysphagia. METHODS: In all, 145 patients (aged 18-85 years, 54% female) with dysphagia that completed upper endoscopy with a 16-cm FLIP assembly and high-resolution manometry (HRM) were included...

BACKGROUND: Histopathology of muscularis externa in primary esophageal motility disorders has been characterized previously. We aimed to correlate the results of high-resolution manometry with those of histopathology. METHODS: During peroral endoscopic myotomy, peroral esophageal muscle biopsy was performed in patients with primary esophageal motility disorders. Immunohistochemical staining for c-kit was performed to assess the interstitial cells of Cajal (ICCs)...

More and more endoscopically gastrointestinal procedures require anesthesiologists to perform general anesthesia, such as "peroral endoscopic myotomy". Peroral endoscopic myotomy is a novel invasive treatment for the primary motility disorder of esophagus, called esophageal achalasia. Despite of its minimally invasive feature, there are still complications during the procedure which develop to critical conditions and threat patients' lives. Herein we describe a case about tension pneumothorax subsequent to esophageal rupture during peroral endoscopic myotomy...

BACKGROUND: Jackhammer esophagus (JE) is a rare esophageal motility disorder defined in the Chicago Classification of Esophageal Motility by presence of excessively high distal contractile integral (DCI) on high-resolution manometry (HRM), with unknown natural manometric course. We examined the development of achalasia over time in patients with JE. METHODS: Through a retrospective longitudinal design, patients with Jackhammer contractions who had more than one HRM between 2005 and 2015 were identified...

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...

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 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 the Mayo Clinic Arizona Rheumatology Scleroderma Clinic for esophageal manometry, from May 2006 through January 2015...

Diagnosis of oesophageal motility disorders has been well established for many years now, although circadian gastrointestinal motility is still purely understood. So far, high-resolution manometry (HRM) is only available for short-term measurement in clinical practice to evaluate simultaneous pressure conditions throughout the esophagus. Thus, only a very limited period of time can be investigated. There is evidence that disorders in esophageal motility can cause severe discomfort and symptoms even though they only tend to occur spontaneously...

The lower esophageal sphincter (LES) is a specialized region of the esophageal smooth muscle that allows the passage of a swallowed bolus into the stomach. Nitric oxide (NO) plays a major role in LES relaxation. Nicorandil possesses dual properties of a NO donor and an ATP-sensitive potassium channel (KATP channel) agonist, and is expected to reduce LES tone. This study investigated the mechanisms underlying the effects of nicorandil on the LES. Rat LES tissues were placed in an organ bath, and activities were recorded using an isometric force transducer...

BACKGROUND: Achalasia is a rare motility disorder of the esophagus. Treatment is palliative with the goal of symptom remission and slowing the progression of the disease. Treatment options include per oral endoscopic myotomy (POEM), laparoscopic Heller myotomy (LM) and endoscopic treatments such as pneumatic dilation (PD) and botulinum toxin type A injections (BI). We evaluate the economics and cost-effectiveness of treating achalasia. METHODS: We performed cost analysis for POEM, LM, PD and BI at our institution from 2011 to 2015...

Esophageal atresia (EA) is a congenital malformation defined by the discontinuity of the esophagus occurring in 2.4 in 10,000 births. As survival rates are high, the significant medical morbidity became more relevant. Short-term and long-term morbidities involve the respiratory and gastrointestinal system in the majority of the patients. The impact of this morbidity seems large enough to inspire researchers to develop experimental animal models that may help understanding the pathogenesis and pathophysiology...

Lymphocytic esophagitis (LE) is a histologic pattern with no established clinical correlates in the majority of patients. The goal of this study was to evaluate the association between nonachalasia primary esophageal motility disorders (PEMD) and LE. Sixty-nine patients with PEMD and esophageal biopsies, including 22 with nutcracker esophagus, 33 with ineffective motility, and 14 with diffuse spasm, constituted the study group. The control group consisted of 70 patients with severe dysmotility-negative gastroesophageal reflux disease requiring referral for Nissen fundoplication...

Hypercontractile esophagus (nicknamed jackhammer esophagus) is a recently defined disease within the esophageal motility disorders classification. Responses to treatments for jackhammer esophagus have been inconsistent in previous trials, possibly due to its heterogeneous manifestation. Thus, we reviewed 10 patients diagnosed with jackhammer esophagus and compared their clinical and manometric features at baseline. Additionally, manometric and symptomatic responses after treatment with known smooth muscle relaxants, including anticholinergic drugs (cimetropium bromide and scopolamine butylbromide) and a phosphodiesterase-5 inhibitor (sildenafil) were compared...

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)...

Upper gastrointestinal tract (GIT) symptoms are not disease specific and of limited value in the differentiation of GIT disorders. The present study aimed to determine the etiology of chronic unspecific symptoms in children and to test the need for upper endoscopy in diagnosis. This is a prospective study for 30 Egyptian children presented with chronic upper GIT symptoms for at least 2 months. History regarding severity and frequency of GIT symptoms were asked for. Children with known disorder that explains presenting symptoms were excluded...
