RESUMO
BACKGROUND: Food bolus obstruction (FBO) leading to hospital treatment is often associated with eosinophilic oesophagitis (EoE), stenosis, or oesophageal cancer (1). Danish national guidelines recommend that patients with FBO undergo a diagnostic upper endoscopy within two weeks of presentation to exclude possible malignancy, and histological evaluation of eight biopsies (2, 3). AIMS: The aims of this study were to (1) report the incidence and describe the causes and treatment of FBO in the North Denmark Region (NDR), (2) determine the proportion of patients who underwent upper endoscopy and biopsy according to regional and national guidelines, and (3) identify International Classification of Diseases 10th Revision (ICD-10) diagnosis and procedure codes applied to the hospital visits due to FBO in the NDR. METHODS: Among all acute hospital visits in the NDR in 2021, all visits with ICD-10 codes possibly reflecting FBO, as well as a random sample of 14,400 visits with unspecific ICD-10 codes (R and Z codes), were screened manually for possible FBO. Diagnosis, follow-up, and treatment of all patients with FBO were recorded. RESULTS: The median patient age was 66.0 (Q1-Q3: 49.8-81.0) years, and half of the patients had experienced FBO before. Two thirds of patients (66.0%) were never diagnosed with a cause of FBO, followed by 17.3% with EoE. 30% of patients did not undergo upper endoscopy within two weeks of the hospital visit, and 50.7% were never biopsied in the oesophagus. Of 1886 hospital visits with registry ICD-10 codes that possibly reflected FBO, 8.4% were due to FBO, while FBO was present in 0.028% of the random sample of unspecific ICD-10 codes. CONCLUSIONS: Most hospitalized FBO patients in the NDR in 2021 were never diagnosed with a cause. In these patients there is a high risk of overlooked EoE or upper gastrointestinal cancers. The area needs immediate focus and changed routines to improve treatment and prevent new FBO.

Background and Aim: The DanEoE is a previously described population- and register-based cohort of 236 adult patients with eosinophilic esophagitis (EoE) in a well-defined Danish region with a population of 580 000 and free medical treatment. The aim of the study was to compare the phenotype and treatment response between EoE patients with complications to patients without complications at diagnosis. Methods: A retrospective cross-sectional study of the DanEoE cohort's 236 adult EoE patients diagnosed between 2007 and 2017 in the North Denmark Region. Patients were divided into a group who had had complications (dilated or food bolus obstruction [FBO]) before or at the diagnosis, and a group without. Results: At the diagnostic endoscopy, 61% had never had a complication, and 39% had either had FBO (n = 77) or been dilated (n = 15). The complicated group had the same mean age at symptom debut (37 [SD = 16] vs 37 [SD = 17] years, P = 1.0), but were diagnosed significantly later with a resulting longer diagnostic delay (13 [SD = 13] vs 7.9 [SD = 11] years, P = 0.01). Almost half of all patients were never treated to symptomatic remission (uncomplicated 40%, complicated 49%). The histological remission was not secured in the majority (uncomplicated 68%, complicated 70%). Despite this, <15% of patients with previous FBO experienced this after the diagnosis. Conclusion: In the population-based DanEoE cohort, results indicated that the complicated EoE phenotype was a patient with a 5-year longer diagnostic delay. In the current study, the complication status did not predict the treatment response.
RESUMO
Eosinophilic esophagitis (EoE) is a leading cause of food bolus impaction in children and adults. The mechanism of dysphagia in EoE, particularly non-obstructive dysphagia, remains incompletely understood. While fibrostenotic processes appear to be critical in the development of dysphagia, somatosensory dysfunction and dysmotility also contribute. This review considers potential mechanisms of dysphagia and evaluates the utility of current and future treatment strategies in this context.

OBJECTIVE: To investigate the characteristics of patients presenting with oesophageal food bolus obstruction (FBO) who achieve early resolution of symptoms, and to assess the impact of medical therapies on the overall time course of FBO. METHODS: A retrospective observational study was performed in a university teaching hospital with regional acute endoscopy services. Patients presenting with symptoms of FBO were identified through clinical coding and demographic, clinical and endoscopic data extracted from the electronic medical record. The primary outcome was the time to resolution defined as the earliest of symptom resolution, endoscopic or surgical intervention or discharge. RESULTS: A total of 116 patients presented with symptoms of FBO. Twenty-seven (23.3%) had early resolution of symptoms and were discharged from the ED without acute endoscopy, the remainder were admitted for further management. Patients discharged from the ED presented to hospital sooner after the onset of symptoms (137 vs 288 min, P < 0.05), but did not differ from those admitted in any other characteristic. Seventy-one (61.2%) patients received medical therapy. There was no statistical difference in the time to resolution between those who received medical therapy and those who did not. Furthermore, the use of medical therapy was associated with a delay in referral for endoscopy (140 vs 100 min, P < 0.05). CONCLUSIONS: Time from symptom onset to presentation is the only predictor of early resolution from FBO, while medical therapy is ineffective in relieving obstruction and may delay definitive therapy. We recommend the use of an institutional management plan to facilitate early access to endoscopy in cases of FBO.

AIM: To look at the relationship between eosinophilic oesophagitis (EO) and food bolus impaction in adults. METHODS: We retrospectively analysed medical records of 100 consecutive patients who presented to our hospital with oesophageal food bolus obstruction (FBO) between 2012 and 2014. In this cohort, 96 were adults (64% male), and 4 paediatric patients were excluded from the analysis as our centre did not have paediatric gastroenterologists. Eighty-five adult patients underwent emergency gastroscopy. The food bolus was either advanced into the stomach using the push technique or retrieved using a standard retrieval net. Biopsies were obtained in 51 patients from the proximal and distal parts of the oesophagus at initial gastroscopy. All biopsy specimens were assessed and reviewed by dedicated gastrointestinal pathologists at the Department of Pathology, University Hospital Geelong. The diagnosis of EO was defined and established by the presence of the following histological features: (1) peak eosinophil counts > 20/hpf; (2) eosinophil microabscess; (3) superficial layering of eosinophils; (4) extracellular eosinophil granules; (5) basal cell hyperplasia; (6) dilated intercellular spaces; and (7) subepithelial or lamina propria fibrosis. The histology results of the biopsy specimens were accessed from the pathology database of the hospital and recorded for analysis. RESULTS: Our cohort had a median age of 60. Seventeen/51 (33%) patients had evidence of EO on biopsy findings. The majority of patients with EO were male (71%). Classical endoscopic features of oesophageal rings, furrows or white plaques and exudates were found in 59% of patients with EO. Previous episodes of FBO were present in 12/17 patients and 41% had a history of eczema, hay fever or asthma. Reflux oesophagitis and benign strictures were found in 20/34 patients who did not have biopsies. CONCLUSION: EO is present in approximately one third of patients who are admitted with FBO. Biopsies should be performed routinely at index endoscopy in order to pursue this treatable cause of long term morbidity.
RESUMO
Acute oesophageal symptoms include acute dysphagia or food bolus impaction (most commonly due to strictures, Schatzki ring and eosinophilic oesophagitis), acute chest pain with odynophagia due to oesophageal infections, motility disorders and acute oesophageal rupture (of which oesophageal intramural haematoma is a subtype). Acute full thickness oesophageal rupture carries a high mortality if not recognised early; the clinical features and conditions with which this may be confused are presented and discussed.

BACKGROUND: Eosinophilic esophagitis (EoE) is a newly recognised condition that is apparently increasing in prevalence, and the aetiology is poorly understood. The role of aeroallergens in EoE is controversial, given the success of dietary therapy. Massive aeroallergen exposure leading to food bolus obstruction events (FBOE) has been described, and the diagnosis of EoE by esophageal biopsy noted to be more common in the pollen season according to previous case series. AIM: To determine if a seasonal variation and a geographical variation occurred in EoE presenting as FBOE in adults, and to track the prevalence of FBOE and EoE over time. METHOD: A retrospective case-control study analysis was performed from January 2002 to January 2012 to identify all FBOE in adults presenting to five tertiary hospitals in Melbourne, Australia. Endoscopy, histopathological reports, case notes and blood tests were examined, and postcodes recorded. Records of pollen counts were obtained. Cases were defined according to esophageal biopsy and grouped based on month of diagnosis. All other causes of FBOE served as controls. RESULTS: One thousand, one hundred and thirty-two FBOE were identified. Biopsies were only performed in 278 of these cases, and 85 patients were found to have EoE after biopsy. Patients with EoE were younger (mean age 38 years, range 18-72) compared with those with alternative diagnosis (mean age 64.4 range 22-92), more likely to be male (M : F = 4:1 compared with 1.68:1 ) and had a higher eosinophil count in venous blood. Overall no seasonality was demonstrated in FBOE secondary to any diagnosis, although the six cases of recurrent FBOE secondary to EoE mainly occurred in the grass pollen season in subsequent years. FBOE cases were evenly distributed throughout metropolitan Melbourne irrespective of population density. EoE as a percentage of FBOE increased over time. CONCLUSION: Seasonal aeroallergens may be important for a subgroup of patients with EoE presenting as recurrent FBOE. Esophageal biopsies are performed in a minority of patients, representing a significant departure from ideal management and contributing to recurrent unnecessary FBOE. EoE is an increasingly important cause of FBOE.

Initial case series describing children and adults with symptoms related to esophageal dysfunction and dense esophageal eosinophilia lead to recognition of a "new" disease, eosinophilic esophagitis (EoE). Clinical, basic, and translational studies have provided a deeper understanding of this somewhat enigmatic disease that mechanistically is defined as an antigen-driven condition limited to the esophagus. This article summarizes many of the key historical features of EoE and provides a glimpse of potential future developments.

Eosinophilic oesophagitis (EoE) is a chronic, antigen mediated disease of the disease of the oesophagus that may present in both adults and children. It is characterised by intermittent dysphagia, food bolus obstruction and weight loss. The pathogenesis is incompletely understood but is thought to culminate in poor compliance, or reduced distensibility. The condition is being reported and studied in the literature with increasing incidence, although equally it is highly likely that the diagnosis is being missed altogether with alarming frequency. Diagnosis of the condition requires at least one oesophageal biopsy with an eosinophil count greater than 15 per high power field. Endoscopic features include trachealisation, furrows, white exudate, narrowing and in the most severe cases stricture formation although none are pathognomonic of the condition. Therapy is often not required, but in the acute setting may take the form of dietary therapy or topical steroids. Long term maintenance therapy is usually only required in the most severe cases and the most effective treatment is the subject of ongoing research. There are a number of hurdles to be overcome in the management of patients with EoE. These include; improving our understanding of the aetiology of the condition, investigating the individual causes, assessing the true disease severity and planning the best long term maintenance therapy. Distinguishing EoE from EoE gastro-oesophageal reflux disease is also a hurdle because the two conditions, both being common, can co-exist. In order to overcome these hurdles, a multifaceted approach is required. The management of food bolus obstruction requires a management algorithm that is accepted and endorsed by a number of specialties. National and international disease registers should be established in order to facilitate future research but more importantly to address areas where further education or increased diagnostic capabilities may be required. Assessment of disease severity should become a key goal, and the development of specific biomarkers for EoE should also be a priority. Finally, randomised controlled trials of new agents are required to assess the best treatment in both the acute and long term setting.
