Acute intramucosal dissection in eosinophilic esophagitis

British Society of Gastroenterology (BSG) and British Society of Paediatric Gastroenterology, Hepatology and Nutrition (BSPGHAN) joint consensus guidelines on the diagnosis and management of eosinophilic oesophagitis in children and adults

BACKGROUND

Eosinophilic oesophagitis (EoE) is an increasingly common cause of dysphagia in both children and adults, as well as one of the most prevalent oesophageal diseases with a significant impact on physical health and quality of life. We have provided a single comprehensive guideline for both paediatric and adult gastroenterologists on current best practice for the evaluation and management of EoE.

METHODS

The Oesophageal Section of the British Society of Gastroenterology was commissioned by the Clinical Standards Service Committee to develop these guidelines. The Guideline Development Group included adult and paediatric gastroenterologists, surgeons, dietitians, allergists, pathologists and patient representatives. The Population, Intervention, Comparator and Outcomes process was used to generate questions for a systematic review of the evidence. Published evidence was reviewed and updated to June 2021. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system was used to assess the evidence and make recommendations. Two rounds of voting were held to assess the level of agreement and the strength of recommendations, with 80% consensus required for acceptance.

RESULTS

Fifty-seven statements on EoE presentation, diagnosis, investigation, management and complications were produced with further statements created on areas for future research.

CONCLUSIONS

These comprehensive adult and paediatric guidelines of the British Society of Gastroenterology and British Society of Paediatric Gastroenterology, Hepatology and Nutrition are based on evidence and expert consensus from a multidisciplinary group of healthcare professionals, including patient advocates and patient support groups, to help clinicians with the management patients with EoE and its complications.

Intramural esophageal dissection with eosinophilic esophagitis

Intramural esophageal dissection (IED), like esophageal perforation, is a rare complication of eosinophilic esophagitis (EoE). A 44-year-old woman who had experienced EoE for 8 years complained of food impaction, severe neck pain, and odynophagia as well as consulted the emergency unit. She was diagnosed with IED with mediastinal emphysema by enhanced computed tomography. After admission, she was treated conservatively with noninvasive treatment, including fasting, intravenous feeding, and antibiotics. Only nine cases of IED with EoE have been previously reported. All were male, and our patient was the first female patient from Asia. Urgent endoscopy was conducted in eight cases, of which three were worse after endoscopy, and in one case, total esophagectomy was conducted due to subsequent esophageal perforation. We did not perform urgent endoscopy on our patient because of a potentially increased risk of esophageal perforation through the procedure. When patients with EoE complain of severe retrosternal pain, odynophagia, or dysphagia, IED should be considered in addition to food impaction.

An Update on Eosinophilic Esophagitis: Etiological Factors, Coexisting Diseases, and Complications

BACKGROUND

Eosinophilic esophagitis (EoE) is an immune-mediated clinicopathological condition characterized by esophageal infiltration with eosinophils resulting in chronic inflammation and stricture.

SUMMARY

The recent increase in the incidence of EoE and the characteristic presentation of symptoms with difficulty swallowing and food bolus impaction has raised key concerns of clinicians as well as researchers. EoE often presents with dysphagia, food impaction, nausea, regurgitation or vomiting, and decreased appetite. It is more common in males, affecting both adults and children. The causative manner of this condition is complex and multifactorial. Throughout recent years, researchers have made a significant contribution to understanding the pathogenesis of EoE, genetic background, natural history, work on allergy, and standardization in the evaluation of disease activity. There is relatively high prevalence of EoE among the population, emphasizing the importance of this disease. Key messages: Esophageal involvement with eosinophils may be manifested as isolated or with coexisting conditions and should be taken into consideration in the differential diagnosis. This study aimed to provide gastroenterologists with novel insights into the evaluation of esophageal involvement with eosinophils and to pay special attention to the etiological factors, coexisting clinical diseases, and complications.

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

Background

The 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 presentation

A 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.

Conclusion

An 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.

Esophageal perforation in eosinophilic esophagitis: A systematic review on clinical presentation, management and outcomes

There is evidence of an increased fragility in the inflamed esophagus of patients with eosinophilic esophagitis (EoE). We performed a systematic review on presentation, management and outcomes of and surgical interventions for esophageal perforation in these patients, by searching in the MEDLINE, Embase and Scopus databases. Of the 599 references identified, 41 full-papers and 9 abstract met the inclusion criteria. Overall, 76 esophageal perforation episodes in 70 individual patients aged between 9 and 65 years were reported. 51 patients had not been diagnosed with EoE at the time of perforation; 14 patients had an untreated disease and the remaining were non responsive to therapy. Acute or progressive pain after long-lasting dysphagia and food impaction was the most common symptom leading to diagnosis in 42 patients who presented with Boerhaave syndrome. Pushing impacted food into the stomach led to perforation in 5 cases. Eight episodes appeared after dilation. CT scans demonstrated perforation in 82.4% of patients. Conservative management (including esophageal stenting) was used in 67.1% patients. The 25 remaining patients underwent surgery. Recovery was uneventful in the vast majority of patients. No death was reported. Active inflammation due to undiagnosed or untreated EoE was present in most cases of esophageal perforation. Conservative treatment of perforation should always be considered in EoE.
