Oesophageal Bolus Obstruction Research Articles

Клинико-морфологическая диагностика эозинофильного эзофагита

Eosinophilic esophagitis (EoE) is an immune-mediated disease that presents with dysphagia and esophageal bolus obstruction and is characterized by predominant intraepithelial eosinophilic infiltration at histology. The aim of our literature review was to delineate clinical and morphological EoE features in terms of differential diagnosis with other esophageal diseases, i.e., gastroesophageal reflux disease (GERD), inflammatory bowel diseases (IBDs), autoimmune diseases, and rare esophageal disorders. Clinical features of dysphagia and esophageal bolus obstruction and endoscopic criteria (according to EREFS) are typical of EoE. Nevertheless, eosinophilia of the esophageal mucosa is not a specific marker of mucosal injury and is not sufficient for EoE diagnosis. Therefore, eosinophilic esophagitis histological scoring system (EoEHSS) was developed. It involves assessment of intraepithelial eosinophilic infiltration, basal zone hyperplasia, eosinophilic abscesses, eosinophil surface layering, dilated intercellular spaces, surface epithelial alteration, dyskeratotic epithelial cells, and lamina propria fibrosis. Complex clinical, endoscopic, and histological evaluation allows accurate diagnosis of EoE and other causal factors of esophageal eosinophilia.

Eosinophilic esophagitis (EoE); a disease that must not be neglected - implications of esophageal rupture and its management

BackgroundThe prevalence of Eosinophilic esophagitis (EoE) is increasing, a severe complication of EoE is spontaneous perforation of the oesophagus. It is of great importance to be aware of this risk and handle this severe complication carefully.Case presentationA middle-age man with EoE since 2004, had a total esophageal bolus obstruction while eating lunch at the local hospital. Drinking water, in an attempt to release it, led to a total intramural ruptur of the esophageal wall. A CT scan detected the injury and a covered esophageal stent was inserted within 2 h from the injury. Despite the immediate hospital care, he developed mediastinitis, were in need of a laparascopy and intensive care. After 8 weeks the stent was removed and the esophagus was considered healed. Biopsies from the esophagus showed an eosinophilic inflammation (65 eosinophils/HPF). Twelve weeks from the injury he was essentially back in his normal state and was discharged from the hospital. He was placed on a 6 weeks course of topical treatment with budesonide, which needed to be extended due to inadequate remission. Remission was achieved after 12 weeks of treatment.ConclusionAn effective topical steroid treatment in EoE patients is important. EoE patients are in risk of oesophageal perforation, if so, management may be conservative but mediastinal drainage is important if significant extravasation occurs and should be instituted from the start.

Endoscopic management of esophageal bolus obstruction using the “oil immersion technique”

Endoscopic management of esophageal bolus obstruction using the “oil immersion technique”

The management of acute oesophageal obstruction from a food bolus. Can we be more conservative?

The objective was to assess the number of patients with acute oesophageal bolus obstruction that resolves spontaneously and to aid the identification of the best practice. This prospective and retrospective case series study at a teaching hospital and a district general hospital in Scotland, UK, involved 37 patients with acute oesophageal obstruction from a food bolus who were observed for 24 h from the beginning of symptoms. The bolus passed spontaneously in 54% of the patients during the observational period. A short observational period following the admission of patients with acute food bolus obstruction is reasonable as it may reduce exposure to surgical morbidity and decrease inpatient stay.

Fiberoptic endoscopic diagnosis and treatment of a congenital esophageal diaphragm.

A 9-month-old infant suffering from dysphagia to solids presented with esophageal bolus obstruction. Using an adult fiberoptic esophagoscope, a congenital web was found at the junction of the middle and distal thirds of the esophagus. Previous direct rigid esophagoscopy and roentgenologic examination had not visualized the web. The web was successfully ruptured and dilated by inserting a guide wire under fiberscopic control and then inserting metal olives, followed later by blind mercury bougienage. This report illustrates the use of adult fiberoptic instruments for diagnosis and treatment in pediatric patients.
