Abstract
Endoscopy plays a critical role in caring for and evaluating the patient with eosinophilic esophagitis (EoE). Endoscopy is essential for diagnosis, assessment of response to therapy, treatment of esophageal strictures, and ongoing monitoring of patients in histologic remission. To date, less-invasive testing for identifying or grading EoE severity has not been established, whereas diagnostic endoscopy as integral to both remains the criterion standard. Therapeutic endoscopy in patients with adverse events of EoE may also be required. In particular, dilation may be essential to treat and attenuate progression of the disease in select patients to minimize further fibrosis and stricture formation. Using a modified Delphi consensus process, a group of 20 expert clinicians and investigators in EoE were assembled to provide guidance for the use of endoscopy in EoE. Through an iterative process, the group achieved consensus on 20 statements yielding comprehensive advice on tissue-sampling standards, gross assessment of disease activity, use and performance of endoscopic dilation, and monitoring of disease, despite an absence of high-quality evidence. Key areas of controversy were identified when discussions yielded an inability to reach agreement on the merit of a statement. We expect that with ongoing research, higher-quality evidence will be obtained to enable creation of a guideline for these issues. We further anticipate that forthcoming expert-generated and agreed-on statements will provide valuable practice advice on the role and use of endoscopy in patients with EoE.

Abstract
Eosinophilic esophagitis (EoE) is a disease entity that has become increasingly recognized in the pediatric population over the last decade and was first recognized as early as 1990. EoE is a clinicopathologic diagnosis with signs and symptoms varying between age groups. The clinical presentation of EoE is variable ranging from milder nonspecific symptoms, such as abdominal pain, vomiting, and dyspepsia, to more severe presentations such as failure to thrive, dysphagia and even food impaction and is dependent on age of diagnosis 2. There is growing body of evidence with regards to the pathophysiology, diagnostic modalities, and treatment options for EoE in the past decade. In this review article, we aim to discuss the disease burden, pathophysiology, diagnostic strategies, and currently available treatment options for EoE based on existing literature.

Abstract
The role of endoscopic procedures, in both diagnostic and therapeutic purposes is continually expanding and evolving rapidly. In this context, endoscopists will encounter patients prescribed on anticoagulant and antiplatelet medications frequently. This poses an increased risk of intraprocedural and delayed gastrointestinal bleeding. Thus, there is now greater importance on optimal pre, peri and post-operative management of anticoagulant and/or antiplatelet therapy to minimise the risk of post-procedural bleeding, without increasing the risk of a thromboembolic event as a consequence of therapy interruption. Currently, there are position statements and guidelines from the major gastroenterology societies. These are available to assist endoscopists with an evidenced-based systematic approach to anticoagulant and/or antiplatelet management in endoscopic procedures, to ensure optimal patient safety. However, since the publication of these guidelines, there is emerging evidence not previously considered in the recommendations that may warrant changes to our current clinical practices. Most notably and divergent from current position statements, is a growing concern regarding the use of heparin bridging therapy during warfarin cessation and its associated risk of increased bleeding, suggestive that this practice should be avoided. In addition, there is emerging evidence that anticoagulant and/or antiplatelet therapy may be safe to be continued in cold snare polypectomy for small polyps (< 10 mm).

Abstract
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.

Abstract
Eosinophilic esophagitis (EoE) is a chronic inflammatory disease of the esophagus associated with an atopic predisposition which appears to be increasing in prevalence over the last few decades. Symptoms stem from fibrosis, swelling, and smooth muscle dysfunction. In the past two decades, the etiology of EoE has been and is continuing to be revealed. This review provides an overview of the effects of genetics, environment, and immune function including discussions that touch on microbiome, the role of diet, food allergy, and aeroallergy. The review further concentrates on the pathophysiology of the disease with particular focus on the important concepts of the molecular etiology of EoE including barrier dysfunction and allergic hypersensitivity.

Successful Esophageal Dilation of Eosinophilic Esophagitis (EoE) Patients With a Previous Postdilation Complication: Start Low and Go Slow. J Clin Gastroenterol 2018; 52:773-777.

Abstract
INTRODUCTION Esophageal dilation is an effective and safe treatment option for fibrostenotic eosinophilic esophagitis (EoE). Despite the safety, adverse events occur, yet there is scarce literature on the best treatment postcomplications. METHODS Patients with diagnosis of EoE (≥15 eosinophils per high-power field) from 2011 to 2015 treated at our center were included. Thirty patients with fibrostenotic disease had records available regarding serial dilation therapy. Eight patients previously experienced complications by outside providers. Groups were created based on history of complication before our dilation versus a group without. Mean difference and odds ratio with 95% confidence interval (CI) were calculated. RESULTS There were 8 complications, 7 occurred during dilation and 1 during passage of the endoscope. Esophageal diameter at initial dilation was lower in patients with prior complications 9.0±1.51 versus 11.73±2.98 mm (95% CI: -4.44, -1.02; P=0.003). However, end-esophageal diameter was similar across both groups 15.8±1.8 versus 16.1±2.0 mm. Total number of dilation sessions: 4.0±1.8 versus 2.32±1.0 (95% CI: 0.17, 3.19; P=0.03), as well as sessions to reach 17 mm diameter 3.8±1.0 versus 2.3±1.0 (95% CI: -0.08, 2.89; P=0.04), were higher in the patients with complications. The length of time in months to reach an esophageal diameter of 17 mm was longer in patients with complications, but the difference was not statistically significant 3.50±0.6 versus 2.3±2.3 months (P=0.09). CONCLUSIONS Esophageal dilation is a safe and effective modality to treat severe fibrostenotic EoE in patients with prior history of complications. The keys to success are: (1) start with lower diameter bougies and (2) dilate slowly over a longer time course to reach targeted diameter and symptom resolution.

Abstract
Eosinophilic esophagitis (EoE) has arisen as a common disorder in current clinical and endoscopic gastroenterology practice. Areas covered: A comprehensive review of the literature to summarize and update different aspects related with the use of endoscopy in the diagnostic workout and treatment of pediatric and adult EoE patients is conducted. Expert commentary: Endoscopic features in EoE are frequently subtle, so were inadverted in some initial reports of the disease. Literature has described a wide number of EoE-associated features, systematized in the EREFS classification, which standardized the grade and severity of exudates, rings, edema, furrows, and strictures. The insufficient reliability of these features to predict eosinophilic inflammation still makes biopsies essential in diagnosing or monitoring EoE. EoE causes half of the food impactions requiring endoscopy; food impaction leads to EoE diagnosis in up to half of cases. Long term consequences of EoE include esophageal remodeling leading to strictures and narrowing, thus impairing symptoms and needs dilation. Recognizing the risks from dilation in EoE required carrying out a safe technique to avoid the high complication rate reported in the early literature. Endoscopic dilation should be considered in patients with esophageal narrowing and dysphagia/food impaction unresponsive to diet or drugs-based anti-inflammatory treatment.

Abstract
GOALS To characterize patients who suffer perforation in the context of eosinophilic esophagitis (EoE) and to identify predictors of perforation. BACKGROUND Esophageal perforation is a serious complication of EoE. MATERIALS AND METHODS We conducted a retrospective cohort study of the University of North Carolina EoE clinicopathologic database from 2001 to 2014. Subjects were included if they had an incident diagnosis of EoE and met consensus guidelines, including nonresponse to a PPI trial. Patients with EoE who had suffered perforation at any point during their course were identified, and compared with EoE cases without perforation. Multiple logistic regression was performed to determine predictors of perforation. RESULTS Out of 511 subjects with EoE, 10 (2.0%) had experienced an esophageal perforation. Although those who perforated tended to have a longer duration of symptoms before diagnosis (11.4 vs. 7.0 y, P=0.13), a history of food impaction (odds ratio, 14.9; 95% confidence interval, 1.7-129.2) and the presence of a focal stricture (odds ratio, 4.6; 95% confidence interval, 1.1-19.7) were the only factors independently associated with perforation. Most perforations (80%) occurred after a prolonged food bolus impaction, and only half of individuals (5/10) carried a diagnosis of EoE at the time of perforation; none occurred after dilation. Six patients (60%) were treated with nonoperative management, and 4 (40%) required surgical repair. CONCLUSIONS Esophageal perforation is a rare but serious complication of eosinophilic esophagitis, occurring in ∼2% of cases. Most episodes are due to food bolus impaction or strictures, suggesting that patients with fibrostenotic disease due to longer duration of symptoms are at increased risk.

Abstract
BACKGROUND AND AIMS Esophageal dilation is a now recognized to be an important therapeutic modality in eosinophilic esophagitis (EoE). We aimed to evaluate the safety of esophageal dilation in EoE, especially regarding perforation risk, and to examine perforation risk by dilator type. METHODS We conducted a systematic review of the published literature from January 1, 1950 to June 30, 2016 using PubMed, EMBASE, and Web of Science. Studies were included if they described patients with EoE who underwent elective esophageal dilation and also reported the presence or absence of at least 1 adverse event (eg, perforation, bleeding, pain, or hospitalization). We used random-effects meta-analysis to estimate the frequency of each adverse event. RESULTS Of 923 identified articles, 37 met inclusion criteria and represented 2034 dilations in 977 patients. On meta-analysis, postprocedure hospitalization occurred in .689% of dilations (95% confidence interval [CI], 0%-1.42%), clinically significant GI hemorrhage in .028% (95% CI, 0%-.217%), and clinically significant chest pain in 3.64% (95% CI, 1.73%-5.55%). Nine perforations were documented, at a rate of .033% (95% CI, 0%-.226%) per procedure after meta-analysis. None of the perforations resulted in surgical intervention or mortality. Most (5/9) were reported before 2009 (rate, .41% [95% CI, 0%-2.75%]); from 2009 forward the rate was .030% (95% CI, 0%-.225%). Dilation method was described in 30 studies (1957 dilations), in which 4 perforations were detected. The estimated perforation rate for bougies was .022% (95% CI, 0%-.347%) and for balloons was .059% (95% CI, 0%-.374%). CONCLUSIONS Perforation from esophageal dilation in EoE is rare, and there is no evidence of a significant difference in perforation risk related to dilator type. Esophageal dilation should be considered a safe procedure in EoE.

Abstract
It is unknown if successful control of esophageal inflammation in eosinophilic esophagitis (EoE) decreases the need for subsequent esophageal dilation. We aimed to determine whether histologic response to topical steroid treatment decreases the likelihood and frequency of subsequent esophageal dilation. We conducted a retrospective cohort study. Patients with an incident diagnosis of EoE were included if they had an initial esophageal dilation, received topical steroids, and had a subsequent endoscopy with biopsies. The number of dilations performed in each group was determined, and histologic responders (<15 eos/hpf) were compared to nonresponders. The 55 EoE patients included (27 responders and 28 nonresponders) underwent a mean of 3.0 dilations over a median follow-up of 19 months. Responders required fewer dilations than nonresponders (1.6 vs. 4.6, P = 0.03), after adjusting for potential confounders. Despite undergoing significantly fewer dilations, responders achieved a similar increase in esophageal diameter with dilation (4.9 vs. 5.0 mm; P = 0.92). In EoE patients undergoing esophageal dilation at baseline, control of inflammation with topical steroids was associated with a 65% decrease in the number of subsequent dilations to maintain the same esophageal caliber. This suggests that inflammation control is an important goal in patients with fibrostenotic changes of EoE.

BACKGROUND Oesophageal dilation is frequently used as an adjunct treatment to alleviate symptoms that develop from fibrostenotic remodelling in eosinophilic oesophagitis (EoE). Earlier reports described an increased risk of complications associated with dilation. AIM Perform a systematic review and meta-analysis to assess the efficacy and safety of endoscopic dilation in children and adults with EoE. METHODS Professional librarians searched MEDLINE, EMBASE, the Cochrane library, Scopus, and Web of Science for articles in any language describing studies of dilation in EoE through December 2016. Studies were selected and data were abstracted independently and in duplicate. Random effects modelling was used to generate summary estimates for clinical improvement and complications (haemorrhage, perforation, hospitalisation, and death). RESULTS The search resulted in 3495 references, of which 27 studies were included in the final analysis. The studies described 845 EoE patients, including 87 paediatric patients, who underwent a total of 1820 oesophageal dilations. The median number of dilations was 3 (range: 1-35). Clinical improvement occurred in 95% of patients (95% CI: 90%-98%, I2 : 10%, 17 studies). Perforation occurred in 0.38% (95% CI: 0.18%-0.85%, I2 : 0%, 27 studies), haemorrhage in 0.05% (95% CI: 0%-0.3%, I2 : 0%, 18 studies), and hospitalisation in 0.67% (95% CI: 0.3%-1.1%, I2 : 44%, 24 studies). No deaths occurred (95% CI: 0%-0.2% I2 : 0%, 25 studies). CONCLUSIONS Endoscopic dilation is consistently effective in children and adults with EoE, resulting in improvement in 95% of patients with very low rates (<1%) of major complications.

Abstract
OBJECTIVES Although several studies report on the experience with adult eosinophilic esophagitis (EoE)-related stricture, outcomes for pediatric patients with EoE-associated fibrostenosis and stricture is more limited. To address this, we aim to identify the adverse event (AE) rate and short-term outcomes of the largest reported cohort of children with EoE to undergo esophageal dilation for management of symptomatic esophageal narrowing. METHODS A retrospective assessment of all children, 18 years and younger, who underwent esophageal dilation at an academic children's hospital during a 5-year period was conducted. Clinical, endoscopic, histologic, and outcomes of dilation were extracted from the medical record. AEs were captured within a standardized endoscopic AE database. Grade 2 AEs (requiring unanticipated medical intervention) were termed significant. Dilation-related events were compared between patients with EoE, without EoE, and those undergoing standard upper endoscopy. RESULTS Of the 451 total dilations, 68 dilations were performed in 40 EoE patients (mean age 13.8 years, standard deviation 3.3 years [4.6-18.9 years]). Forty-three percent (17/40) had repeat dilation during the study period. Dilation-related grade 2 AE rates in EoE and in non-EoE patients were 2.9% and 3.1%, respectively (P > 0.5). Chest pain (any grade AE) was reported in 14.7% of EoE dilations. No significant associations were found between postprocedural pain and dilation method, final dilator size, medical therapy, or esophageal eosinophilia. No perforations or significant hemorrhage were reported. CONCLUSIONS We conclude that dilation can be performed safely in children with EoE. In the appropriate clinical setting, cautious dilation may be considered in the management of fibrostenotic EoE.

Abstract
BACKGROUND Eosinophilic esophagitis (EoE) is a chronic, immune-mediated disorder of the esophagus characterized by mucosal eosinophilic infiltration. Topical glucocorticoids are considered standard line of treatment, whereas endoscopic dilations are performed for patients presenting with treatment-resistant disease or manifestations of dysphagia and/or food impactions. Efficacy and safety of esophageal dilation in these patients are currently unclear. AIMS Primary outcomes were to evaluate the efficacy, adverse events, and mortality rates of endoscopic esophageal dilation in patients with EoE. METHODS STUDY SELECTION CRITERIA:: Studies that reported the use of esophageal dilation in EoE patients were included in this meta-analysis. DATA COLLECTION AND EXTRACTION Articles were searched in Medline, Pubmed, and Ovid journals. Two authors independently searched and extracted data. The study design was written in accordance to PRISMA statement. Clinical improvement was defined as patient-reported symptom relief noted by the authors of individual studies. The symptoms were assessed on various nonstandardized, however, relevant questionnaires that were deemed appropriate by the senior authors of individual studies. STATISTICAL METHOD Pooled proportions were calculated using fixed- and random-effects model. I statistic was used to assess heterogeneity among studies. RESULTS Initial search identified 491 reference articles, in which 39 articles were selected and reviewed. Data were extracted from 14 studies (N = 1607) using esophageal dilation for EoE management, which met the inclusion criterion. Mean age of patients was 41years. Pooled patients included 75% males. The pooled proportion of patients that showed clinical improvement with esophageal dilations, after the median follow-up period of 12 months, was 84.95%. No procedure-related deaths were noted. The pooled proportion of patients with post procedural esophageal perforation, chest pain, hospitalization, deep mucosal tear (involving muscularis propria), small mucosal tear, and hemorrhage were 0.61%, 0.06%, 0.74%, 4.04%, 22.32%, and 0.38% respectively. I (inconsistency) was 0% (95% confidence interval [CI] = 0-49.8) and Egger: bias was 0.06 (95% CI = -0.30 to 0.42). CONCLUSIONS In patients with conformed diagnosis of EoE, endoscopic esophageal dilation seems to be an effective and safe treatment option. Majority patients with chest pain and deep mucosal tears did not require hospitalization and symptoms were self-limiting.

Abstract
There are currently limited data on the management of eosinophilic esophagitis (EoE) during pregnancy. At our center, however, we have followed several pregnant women with EoE and others have asked pertinent questions in pre-pregnancy counseling. The relatively young age of patients with EoE implies that many practitioners will also encounter patients with these questions. In this review, we use four cases to prompt a discussion about concerns focused on the safety of steroids and diet therapy during pregnancy and breast-feeding, potential nutritional risks with dietary elimination, how to optimize therapy, and whether endoscopic evaluation for monitoring of disease activity is safe during pregnancy and breast-feeding. An additional concern is whether the disease could progress during pregnancy and breast-feeding if no therapies are used. Although there are no studies specifically examining pregnant EoE patients, we have reviewed the literature relevant to this population as informed by the treatment of inflammatory bowel disease patients during pregnancy, where these issues have been studied in more depth. Providers who care for EoE patients who could become pregnant should familiarize themselves with these issues.

Abstract
Eosinophilic esophagitis (EoE) is a clinico-pathological entity with esophageal symptoms and dense esophageal eosinophilic infiltration throughout the esophagus that may persist despite treatment with proton pump inhibitors. This eosinophilic infiltration is usually absent in the stomach, small intestine and colon, although there are a number of reports of patients with a multi-organ involvement. EoE is associated with abnormalities involving TH2-dependent immunity, with multiple environmental factors strongly contributing to disease expression. The layer of the esophagus affected by the eosinophilic infiltration causes the specific symptoms. Esophageal involvement results mostly in dysphagia for solids that can be severe enough to cause recurrent esophageal obstruction with typical endoscopic features suggesting esophageal remodeling and pathological changes of eosinophilic infiltration of the mucosa, sub-epithelial fibrosis and muscle hypertrophy. This disease is frequently associated with other allergic conditions such as allergic asthma, allergic dermatitis and eosinophilia. The treatment of patients with EoE depends on the severity of the symptoms and of the inflammatory process as well as to their response to a gradual step-up treatment. The first line of treatment consists of steroid containing local inhalers. If unresponsive they are then treated with oral steroids. Intravenous interleukin blockers seem to have a consistent positive therapeutic effect.

Abstract
OBJECTIVES Esophageal dilation is commonly performed in eosinophilic esophagitis (EoE), but there are few long-term data. The aims of this study were to assess the safety and long-term efficacy of esophageal dilation in a large cohort of EoE cases, and to determine the frequency and predictors of requiring multiple dilations. METHODS We conducted a retrospective cohort study in the University of North Carolina EoE Clinicopathological Database from 2002 to 2014. Included subjects met consensus diagnostic criteria for EoE. Clinical, endoscopic, and histologic features were extracted, as were dilation characteristics (dilator type, change in esophageal caliber, and total number of dilations) and complications. Patients with EoE who had undergone dilation were compared with those who did not and also stratified by whether they required single or multiple dilations. RESULTS Of 509 EoE patients, 164 were dilated a total of 486 times. Those who underwent dilation had a longer duration of symptoms before diagnosis (11.1 vs. 5.4 years, P<0.001). Ninety-five patients (58%) required >1 dilation (417 dilations total, mean of 4.4±4.3 per patient). The only predictor of requiring multiple dilations was a smaller baseline esophageal diameter. Dilation was tolerated well, with no major bleeds, perforations, or deaths. The overall complication rate was 5%, primarily due to post-procedural pain. Of 164 individuals dilated, a majority (58% or 95/164) required a second dilation. Of these individuals, 75% required repeat dilation within 1 year. CONCLUSIONS Dilation in EoE is well-tolerated, with a very low risk of serious complications. Patients with long-standing symptoms before diagnosis are likely to require dilation. More than half of those dilated will require multiple dilations, often needing a second procedure within 1 year. These findings can be used to counsel patients with fibrostenotic complications of EoE.

Abstract
Eosinophilic esophagitis (EoE) is a chronic inflammatory condition characterized by esophageal dysfunction and eosinophilic infiltrate (≥15/hpf) in the esophageal epithelium and the absence of other potential causes of eosinophilia. The prevalence is increasing and is the most common cause of solid food dysphagia in children and young adults. This article will review the diagnosis and management of EoE based on consensus conferences, systematic reviews, and meta-analysis and highlights seminal studies in our evolving treatment of this disease. However, all answers are not available and I will remark about the lessons learned in my clinical practice seeing EoE patients over the last 25 years. The complicated etiology of the complaint of dysphagia in EoE patients will be reviewed. The importance of utilizing endoscopy, biopsies, and barium esophagram to help define the 2 phenotypes (inflammatory, fibrostenosis) of EoE will be highlighted. The controversy about PPI-responsive esophageal eosinophilia will be discussed and contrasted with idiopathic EoE. Finally, the 3 treatment options for EoE (drugs, diet, dilation) will be reviewed in detail and a useful clinical management algorithm presented.

Abstract
BACKGROUND Eosinophilic oesophagitis is a chronic, immune/antigen-mediated oesophageal disease, only recently, but increasingly, recognised in the world literature. It is diagnosed and managed primarily by medical gastroenterologists and allergy specialists, and is a distinct disease entity, affecting both children and adults. Few studies have been published in otolaryngology journals, although otolaryngologists will encounter patients with undiagnosed eosinophilic oesophagitis. Patients may present with dysphagia, bolus obstruction or with other ENT disorders, such as atopic rhinitis, reflecting the underlying systemic allergic disorder. OBJECTIVE This paper systematically reviews the evidence base published on the epidemiology, clinical presentation, diagnosis, treatment and prognosis of eosinophilic oesophagitis, particularly as it relates to otolaryngology practice.

Abstract
Tissue remodeling with scaring is common in adult EoE patients with long standing disease. This is the major factor contributing to their complaints of solid food dysphagia and recurrent food impactions. The best tests to define the degree of remodeling are barium esophagram, high resolution manometry and endoscopy. Many physicians are fearful to dilate EoE patients because of concerns about mucosal tears and perforations. However, multiple recent case series attest to the safety of esophageal dilation and its efficacy with many patients having symptom relief for an average of two years. This chapter will review the sordid history of esophageal dilation in EoE patients and outline how to perform this procedure safely. The key is graduated dilation over one to several sessions to a diameter of 15-18 mm. Postprocedural pain is to be expected and mucosal tears are a sign of successful dilation, not complications. In some healthy adults, occasional dilation may be preferred to regular use of medications or restricted diets. This approach is now supported by recent EoE consensus statements and societal guidelines.

Abstract
The gastrointestinal (GI) tract provides an intriguing organ for considering the eosinophil's role in health and disease. The normal GI tract, except for the esophagus, is populated by eosinophils that are present throughout the mucosa, raising the possibility that eosinophils participate in innate mechanisms of defense. However, data from clinical studies associates increased numbers of eosinophils with inflammatory GI diseases, prompting concerns that eosinophils may have a deleterious effect on the gut. We present clinical features of 4 disease processes that have been associated with eosinophilia and suggest areas requiring investigation as to their clinical significance and scientific relevance.

A 43-year woman with a 4-year history of swallowing difficulty for solids presented with absolute dysphagia, which was only slightly relieved by intravenous relaxant given in the emergency department. Barium swallow showed a smooth polypoid filling defect in the mid-oesophagus, with a hold-up at this level. Gastroscopy showed a narrowed ringed oesophagus with an impacted foreign body. This was extracted with a basket, with relief of the dysphagia. Oesophageal biopsies confirmed the diagnosis of eosinophilic esophagitis.

Abstract
Eosinophilic esophagitis (EoE) is a chronic immune/antigen-mediated clinicopathologic condition that has become an increasingly important cause of upper gastrointestinal morbidity in adults and children over the past 2 decades. It is diagnosed based on symptoms of esophageal dysfunction, the presence of at least 15 eosinophils/high-power field in esophageal biopsy specimens, and exclusion of competing causes of esophageal eosinophilia, including proton pump inhibitor-responsive esophageal eosinophilia. We review what we have recently learned about the clinical aspects of EoE, discussing the clinical, endoscopic, and histological features of EoE in adults and children. We explain the current diagnostic criteria and challenges to diagnosis, including the role of gastroesophageal reflux disease and proton pump inhibitor-responsive esophageal eosinophilia. It is also important to consider the epidemiology of EoE (with a current incidence of 1 new case per 10,000 per year and prevalence of 0.5 to 1 case per 1000 per year) and disease progression. We review the main treatment approaches and new treatment options; EoE can be treated with topical corticosteroids, such as fluticasone and budesonide, or dietary strategies, such as amino acid-based formulas, allergy test-directed elimination diets, and nondirected empiric elimination diets. Endoscopic dilation has also become an important tool for treatment of fibrostenotic complications of EoE. There are a number of unresolved issues in EoE, including phenotypes, optimal treatment end points, the role of maintenance therapy, and treatment of refractory EoE. The care of patients with EoE and the study of the disease span many disciplines; EoE is ideally managed by a multidisciplinary team of gastroenterologists, allergists, pathologists, and dieticians.

Abstract
Eosinophilic esophagitis (EoE) is a pathophysiologically complex disorder driven by distinct, multiple mechanisms involving a large number of cells, molecules, and genes. Associated with food allergy from its initial descriptions, a key role for the Th2-type cytokines IL-5 and IL-13 in recruiting and activating eosinophils has been described. Epithelial cells have been recognized as major effectors in initiating EoE, both through their recruitment of iNKT cells towards the esophageal epithelium, which constitutes a major cytokine source, and through the release of eotaxin-3 and other chemoattractants. Epithelial and mesenchymal-released TSLP is a key regulator for which a connecting role between the adaptive and innate mucosal-associated immune response has been suggested. Finally, activated eosinophil- and mast cell-derived TGF β1 secretion is crucial in EoE-associated tissue remodeling.

Abstract
OPINION STATEMENT Eosinophilic esophagitis (EoE) is recognized as an increasingly common cause of chronic and recurrent esophageal symptoms that significantly impact quality of life and may occasionally result in severe complications in both pediatric and adult patients. The disease is triggered and maintained by exposure to food antigens in most patients, with an additional role proposed for airborne allergens. Different diet-based approaches focused on restricting potentially offending foods have proven to be effective long-term therapies for EoE. Dietary therapy is thus an attractive, yet challenging treatment option that should be considered for all pediatric and adult EoE patients. However, limitations related to food restriction, patient willingness to undergo repeated endoscopies and biopsies, and the variable results of allergy testing imply that dietary management is for the most part currently restricted to highly motivated healthcare providers treating highly motivated patients reluctant to utilize drug-based therapy on a chronic basis. Pharmacological therapies for EoE mainly comprise swallowed topical steroids, especially fluticasone propionate and budesonide, which were originally developed to treat bronchial asthma and are now extensively used "off label" in EoE patients. In fact, topical steroids currently constitute the prevailing therapeutic option and will probably continue to do so in the near future; indeed, several randomized clinical trials are currently underway to test these drugs for approval as the first pharmacological agents for EoE patients. Immunomodulators and several anti-allergic agents must be further assessed as therapeutic alternatives for refractory cases or patients with complications. Endoscopic dilation represents the third pillar in the therapeutic management of EoE patients, since they frequently present reductions in the esophageal caliber as a result of collagen deposition and a progressive fibrous remodeling process promoted by chronic eosinophilic infiltration. Dilation provides at least temporary symptom relief with similar complication rates to esophageal strictures from a different origin. However, although repeated endoscopic dilation has sometimes been used as the sole therapy for EoE, it best constitutes an adjuvant therapy along with dietary or pharmacological-based interventions, especially since dilation has no effect on the underlying esophageal inflammation. Current therapeutic management of EoE varies widely, with physician experience being a major explanatory factor. New evidence from ongoing research on EoE should thus seek to define a common treatment algorithm to optimize EoE patient management.

Abstract
BACKGROUND Oesophageal dilation is one of the most effective options in the management of symptoms of eosinophilic oesophagitis (EoE). However, earlier reports described an increased rate of complications. AIM To perform a meta-analysis of population-based studies of the risks associated with dilation and the clinical efficacy and duration of response to dilation in EoE. METHODS Using MEDLINE and EMBASE, a systematic search was performed for published articles since 1977 describing cohort or randomised controlled trials of dilation in EoE. Summary estimates, including 95% confidence interval (CI), were calculated for the occurrence of complications associated with dilations (perforations, haemorrhage, chest pain, lacerations) and percentage of patients with symptom improvement following dilation. Heterogeneity was calculated using the I² statistic. RESULTS The search resulted in 232 references, of which 9 studies were included in the final analysis. The studies described 860 EoE patients, of whom 525 patients underwent at least one oesophageal dilation and a total of 992 dilations. There were three cases of perforation (95% CI 0-0.9%, I² 0%) and one haemorrhage (95% CI 0-0.8%, I² 0%). Six studies reported postprocedural chest pain in 2% of cases (95% CI 1-3, I² 53%). Clinical improvement from dilation occurred in 75% of patients (95% CI 58-93%, I² 86%). CONCLUSIONS Dilation in patients with eosinophilic oesophagitis is a safe procedure with a low rate of serious complications (<1%), and seems to result in at least a short-term improvement of symptoms in the majority of patients.

Abstract
Eosinophilic esophagitis (EoE) is a chronic immune-mediated condition whereby infiltration of eosinophils into the esophageal mucosa leads to symptoms of esophageal dysfunction. EoE is encountered in a substantial proportion of patients undergoing diagnostic upper endoscopy. This review discusses the clinical, endoscopic, and histologic features of EoE and presents the most recent guidelines for its diagnosis. Selected diagnostic dilemmas are described, including distinguishing EoE from gastroesophageal reflux disease and addressing the newly recognized clinical entity of proton-pump inhibitor-responsive esophageal eosinophilia. Also highlighted is evidence to support both pharmacologic and nonpharmacologic treatments, including topical corticosteroids, dietary elimination therapy, and endoscopic dilation.

Abstract
Eosinophilic esophagitis (EoE) is a relatively new entity with a significant amount of increased recognition over the last decade. The mainstay treatments of EoE are designed to eliminate the causative allergens or to reduce their effects on the esophageal mucosa. Common treatments include dietary modification, proton pump inhibitors, systemic and topical corticosteroids, and endoscopic treatments. As the pathogenesis of EoE is explored, new and novel treatments are being studied that target specific pathways and chemokines identified in as precipitating agents of EoE. This is a rapidly evolving field with significant ongoing research and clinical studies. Our review will therefore focus on current and novel treatment approaches to the disease.
