Abstract
Abstract Objective To describe high resolution manometry features of a population of symptomatic patients with Chagas' disease esophagopathy (CDE). Methods Sixteen symptomatic dysphagic patients with CDE [mean age (54.81±13.43) years, 10 women] were included in this study. All patients underwent a high resolution manometry. Results Mean lower esophageal sphincter (LES) extension was (3.02±1.17) cm with a mean basal pressure of (15.25±7.00) mmHg. Residual pressure was (14.31±9.19) mmHg. Aperistalsis was found in all 16 patients. Achalasia with minimal esophageal pressurization (type 1) was present in 25% of patients and achalasia with esophageal compression (type 2) in 75%, according to the Chicago Classification. Upper esophageal sphincter (UES) mean basal pressure was (97.96±54.22) mmHg with a residual pressure of (12.95±6.42) mmHg. Conclusions Our results show that LES was hypotensive or normotensive in the majority of the patients. Impaired relaxation was found in a minority of our patients. Aperistalsis was seen in 100% of patients. UES had impaired relaxation in a significant number of patients. Further clinical study is needed to investigate whether manometric features can predict outcomes following the studies of idiopathic achalasia.

Dear Editor: High-resolution manometry (HRM) is a revolutionary tool in the field of esophageal function tests. It is a valuable and incomparable instrument to assess the esophageal sphincters and segmental defects of esophageal body peristalsis due to a “panoramic” and simultaneous view from the pharynx to the stomach. Furthermore, it is quicker, more comfortable, and does not share some of the limitations of conventional manometry such as motion artifacts. Ayazi et al. from DeMeester group rec...

Although Chagas disease was only discovered in 1909, it began millions of years ago as an enzootic disease among wild animals. Its transmission to man began accidentally as an anthropozoonosis when mankind invaded wild ecotopes. Endemic Chagas disease became established as a zoonosis over the last 200–300 years through deforestation for agriculture and livestock rearing and adaptation of triatomines to dwellings and to humans and domestic animals as food sources. When T. cruzi is transmitted to ...

Background & Aims: Although the diagnosis of achalasia hinges on demonstrating impaired esophagogastric junction (EGJ) relaxation and aperistalsis, 3 distinct patterns of aperistalsis are discernable with high-resolution manometry (HRM). This study aimed to compare the clinical characteristics and treatment response of these 3 subtypes. Methods: One thousand clinical HRM studies were reviewed, and 213 patients with impaired EGJ relaxation were identified. These were categorized into 4 groups: ac...

Background Esophageal achalasia is characterized by the absence of esophageal peristalsis and by a dysfunctional lower esophageal sphincter (LES). Descriptions of clinical, radiological, and manometric findings in patients with achalasia usually have been based on small numbers of patients. This study was designed to determine in patients with untreated achalasia: (1) clinical presentation; (2) how often a diagnosis of gastroesophageal reflux disease (GERD) was erroneously made based on the pres...

Brazilian surgeons deal routinely with esophageal motility disorders, because achalasia is highly prevalent in Brazil due to Chagas' disease. In the last years new technologies for the evaluation of esophageal motility became available. High resolution manometry and the combination of barometric parameters and intraluminal impedance are the new frontiers on this topic. The authors reviewed current, national and international, literature about achalasia with multichannel intraluminal impedance an...

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 classi...

Chagas disease began millions of years ago as an enzootic disease of wild animals and started to be transmitted to man accidentally in the form of an anthropozoonosis when man invaded wild ecotopes. Endemic Chagas disease became established as a zoonosis over the last 200-300 years through forest clearance for agriculture and livestock rearing and adaptation of triatomines to domestic environments and to man and domestic animals as a food source. It is estimated that 15 to 16 million people are ...

INTRODUCTION: Systemic sclerosis (SSC) is an autoimmune disorder that affects several organs of unknown etiology, characterized by vascular damage and fibrosis of the skin and organs. Among the organs involved are the esophagus and the lung. OBJECTIVES: To relate the profile of changes in esophageal electromanometry (EM), the profile of skin involvement, interstitial pneumopathy (ILD), and esophageal symptoms in SSC patients. METHODS: This is an observational, cross-sectional study carried out a...

The digestive form of Chagas is characterized by alterations in motor, secretory, and absorptive functions of the gastrointestinal tract seen in chronic phase of the disease. It is related to denervation of the enteric nervous system that may occur along the entire digestive tract. As a result of this denervation, digestive motility disturbances occur, leading to loss of coordination of peristalsis and relaxation of the sphincters, resulting in progressive dilation—megaformations, notably in the...

: Achalasia may present in a non-advanced or an advanced (end stage) stage based on the degree of esophageal dilatation. Manometric parameters and esophageal caliber may be prognostic for the outcome of treatment. The correlation between manometry and disease stage has not been yet fully studied. This study aims to describe high-resolution manometry findings in patients with achalasia and massive dilated megaesophagus. Eighteen patients (mean age 61 years, 55% females) with achalasia and massive...

Introduction Gastrointestinal involvement affects 30–40% of the patients with chronic Chagas disease. Esophageal symptoms appear once the structural damage is established. Little is known about the usefulness of high resolution manometry to early identification of esophageal involvement. Method We performed a cross-sectional study at the Vall d’Hebron University Hospital (Barcelona, Spain) between May 2011 and April 2012. Consecutive patients diagnosed with Chagas disease in the chronic phase we...

Chagas’ disease (CD) is highly prevalent in South America; however, the United States and a number of non-endemic countries in Europe and Western Pacific Region have experienced a considerable increase in number of T. cruzi-infected individuals, especially due to migration of people from endemic countries. The disease is caused by the protozoan Trypanossoma cruzy, a flagellated protozoan that is transmitted to humans by a blood-sucking insect. CD is a disease similar to idiopathic achalasia, alt...

Background Digestive damage due to Chagas disease (CD) occurs in 15–20% of patients diagnosed as a result of peristaltic dysfunction in some endemic areas. The symptoms of chronic digestive CD are non-specific, and there are numerous confounders. Diagnosis of CD may easily be missed if symptoms are not evaluated by a well trained physician. Regular tests, as barium contrast examinations, probably lack the necessary sensitivity to detect early digestive damage. Methods 71 individuals with T. cruz...

Summary In patients with chronic indeterminate Chagas disease, conventional manometry has shown that 25–48% had esophageal motor disorders. Recently, esophageal high-resolution manometry (HRM) has revolutionized the assessment of esophageal motor function. In this study, we performed esophageal HRM in a group of subjects with incidentally positive serological findings for Trypanosoma cruzi. In this prospective observational study, we evaluated subjects who had positive serological tests for Chag...

Summary The comparison between idiopathic achalasia (IA) and Chagas' disease esophagopathy (CDE) may evaluate if treatment options and their outcomes can be accepted universally. This study aims to compare IA and CDE at the light of high-resolution manometry. We studied 86 patients with achalasia: 45 patients with CDE (54% females, mean age 55 years) and 41 patients with IA (58% females, mean age 49 years). All patients underwent high-resolution manometry. Upper esophageal sphincter parameters w...
