Volumetric laser endomicroscopy (VLE) is an advanced endoscopic imaging technique that provides high-resolution mucosal and submucosal images of the esophagus. VLE has been used in surveillance Barrett's esophagus (BE) patients undergoing treatment BE neoplasia. Several image-interpretation scoring systems have developed tested. Advances system, such as addition color to areas image marking muc...

This study aims to investigate the association between transporter associated with antigen processing 1 gene (TAP1) polymorphism and esophagus cancer in a Han Gansu population. TAP1 637A/G polymorphism was analyzed in 200 Han Gansu patients with esophagus cancer and 100 ethnically matched healthy Gansu population by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). ...

A subthreshold pharyngeal stimulus induces lower esophageal sphincter (LES) relaxation and inhibits progression of ongoing peristaltic contraction in the esophagus. Recent studies show that longitudinal muscle contraction of the esophagus may play a role in LES relaxation. Our goal was to determine whether a subthreshold pharyngeal stimulus induces contraction of the longitudinal muscle of the ...

We report a case of a male, aged 84, with type 2 diabetes, arterial hypertension, ischemic cardiomyopathy and chronic renal disease. We placed a percutaneous endoscopic gastrostomy one year ago, and we did not notice any injuries in the esophagus. We performed an urgent gastroscopy because the patient had an episode of coffee-ground vomit. In the distal third of the esophagus the mucosa had a n...

Distension of the esophagus can cause heartburn and chest pain; however, none of the available techniques to study the esophagus measure esophageal distension. We evaluated the technique of high-frequency intraluminal ultrasound probe (HFIUS) to measure the esophageal cross-sectional area (CSA) during gastroesophageal reflux (GER). The following methods were used: 1) the CSA of agarose gel tube...

OBJECTIVE To outline current concepts regarding etiology, diagnosis, and treatment of intestinal metaplasia of the esophagus and cardia. SUMMARY BACKGROUND DATA Previously, endoscopic visualization of columnar mucosa extending a minimum of 3 cm into the esophagus was sufficient for the diagnosis of Barrett's esophagus, but subsequently the importance of intestinal metaplasia and the premalign...

Introduction: Foreign bodies in the esophagus are considered to be a life-threatening condition in adults and children because of esophageal perforation, chemical pneumonitis, airway obstruction, and development of a fistula, leading to high morbidity and mortality with this condition. Most cases present with immediate symptoms. However, in rare cases, the foreign body can migrate within the t...

The aim of this study was to determine the role of peripheral reflexes in initiation of the esophageal phase of swallowing. In 10 decerebrate cats, we recorded electromyographic responses from the pharynx, larynx, and esophagus and manometric data from the esophagus. Water (1-5 ml) was injected into the nasopharynx to stimulate swallowing, and the timing of the pharyngeal and esophageal phases ...

OBJECTIVE: To evaluate the effect of cisapride and chest physical therapy on the gastroesophageal reflux of wheezing babies. METHODS: We prospectively assessed the presence of technetium ((99)Tc) in the upper, middle, and lower esophagus of 25 wheezing babies (13 with GERD and 12 without GERD) using scintigraphy. Both groups underwent clinical investigation, including laboratory, X-ray and scin...

The report presents a brief historical outline of spontaneous rupture the esophagus, modern data on incidence disease, difficulties in diagnosis and treatment, as well high complications mortality this pathology. A case successful staged treatment patient with esophagus complicated by purulent mediastinitis pleural empyema, who was admitted 6 days after onset is described. surgical tactics feat...
