Esophageal foreign bodies and eosinophilic esophagitis--the need for esophageal mucosal biopsy: a 12-year survey across pediatric subspecialties

Long-term Follow-up for Missed Cases of Eosinophilic Esophagitis in Children With Previous Foreign Body in the Esophagus

OBJECTIVES

A foreign body impacted in the esophagus could be a sign of eosinophilic esophagitis (EoE). Our aim was to investigate if children previously diagnosed with a foreign body in the esophagus had a missed diagnosis of EoE.

METHODS

In this population-based longitudinal study, all children (0-18 years) diagnosed with a foreign body in the esophagus in Stockholm, Sweden 2006 to 2016, were identified. In addition to a review of medical files, each family was contacted (n = 325) and asked standardized questions. Children with symptoms indicating EoE were offered esophagogastroduodenoscopy (EGD).

RESULTS

We found 325 pediatric cases of foreign body. Two hundred and seven (64%) underwent an endoscopy at the event, 3 of these had biopsies taken, whereby 2 were diagnosed with EoE. Six additional patients were diagnosed with EoE between the initial event and the study follow-up. Children with persisting symptoms suggestive of EoE at the follow-up (n = 21), were offered EGD whereof 7 accepted. Four new cases of EoE were found. Hence, 12 (3.7%) of the children with a previous foreign body, either spontaneously released or endoscopically removed, were diagnosed with EoE. In the structured interview, dysphagia, food impactions and drinking excessively with meals, as well as food allergies, were significantly more common in EoE patients.

CONCLUSIONS

Children with a foreign body in the esophagus are at risk of having EoE. Biopsies should be taken during foreign body removal and questions about swallowing problems and allergic diseases should be carefully explored also in children who do not need EGD because of spontaneous release.

Increase in foreign body and harmful substance ingestion and associated complications in children: a retrospective study of 1199 cases from 2005 to 2017

Background

Children with a history of caustic or foreign body ingestion (FBI) seem to be presenting more frequently to emergency departments. This study aims to elucidate the clinical presentation, diagnostic procedures, and complications associated with the ingestion of different object categories over a 13-year time period.

Methods

A structured retrospective data analysis of patients who presented between January 2005 and December 2017 to the University Medical Centre Ulm was performed. Patients up to 17 years of age with food impaction or foreign body or harmful substance ingestion were included by selection of the corresponding International Statistical Classification of Diseases and Related Health Problems (ICD10-GM) codes. Descriptive statistics, parametric or non-parametric tests, and linear regression analysis were performed.

Result

In total, 1199 patients were analysed; the mean age was 3.3 years (SD 3.12; range 7 days to 16 years), the male to female ratio was 1.15:1, and 194 (16.2%) were hospitalized. The number of patients seen annually increased from 66 in 2005 to 119 in 2017, with a rise in percentage of all emergency patients from 0.82% in 2010 to 1.34% in 2017. The majority of patients (n = 619) had no symptoms, and 244 out of 580 symptomatic patients complained of retching or vomiting. Most frequently, ingested objects were coins (18.8%). Radiopaque objects accounted for 47.6%, and sharp objects accounted for 10.5% of the ingested foreign bodies, both of which were significantly more often ingested by girls (p < 0.001 for both). Button battery ingestion was recorded for 63 patients with a significant annual increase (R2 = 0.57; β = 0.753; p = 0.003). The annual rate of complications also increased significantly (R2 = 0.42; β = 0.647; p = 0.017).

Conclusion

We found an alarming increase in the number of children who presented to our emergency department with FBI and associated complications. A standardized diagnostic and therapeutic approach may reduce and prevent serious complications. Further preventive measures within the home environment are needed to stop this trend.

Systematic review of rigid and flexible esophagoscopy for pediatric esophageal foreign bodies

BACKGROUND

Esophageal foreign body (EFB) is a common presentation in pediatric hospitals. Rigid and flexible esophagoscopy are both primary modalities used for EFB removal. By systematically reviewing the literature, we sought to assess success and complication rates of both rigid and flexible esophagoscopy in pediatric EFB retrieval.

METHODS

A systematic search of the literature was performed in MEDLINE, Embase, Cochrane Database of Systematic Reviews, Web of Science, CINAHL. Two authors independently reviewed 74 abstracts and included studies that documented success rates of flexible and rigid esophagoscopy for EFB retrieval. The certainty and quality of the overall body of evidence was evaluated in accordance with the Grades of Recommendation, Assessment, Development and Evaluation approach.

RESULTS

Five retrospective chart reviews published between 1993 and 2016 identified 955 patients with a mean age of 4.2 (range 3.2-5.3 years). Foreign bodies were localized to the upper esophagus in 69.6%, middle esophagus in 13.0% and lower esophagus in 11.5%. Coins (82.1%) and food boluses (8.5%) comprised the majority of EFB. The success rate of foreign body retrieval was 95.4% with rigid esophagoscopy and 97.4% with flexible esophagoscopy. Complication rates were 2.4% for rigid esophagoscopy and 3.4% for flexible esophagoscopy. Rates of successful foreign body retrieval (odds ratio [OR] = 1.9 [95% CI 0.9-3.8; p = 0.07]) and complications (OR = 0.9 [95% CI 0.3-2.3; p = 0.79]) were not significantly different across modalities. There were no mortalities in any of the studies analyzed.

CONCLUSION

Flexible and rigid esophagoscopy are equally safe and effective for the retrieval of EFB in children. Otolaryngologists, gastroenterologists, and pediatric general surgeons can be consulted for foreign body retrieval depending on institutional policies and resource availability.

Eosinophilic Esophagitis-A Primer for Otolaryngologists

Importance

Eosinophilic esophagitis (EoE) is a chronic, inflammatory condition of the esophagus. Prevalence of EoE is on the rise and, owing to its associated extragastrointestinal manifestations and comorbidities, otolaryngologists are increasingly encountering this condition in their practice.

Observations

Symptoms of EoE are vague and vary greatly based on patient's age. The gastrointestinal symptoms include dysphagia, food impaction, feeding difficulties, symptoms mimicking gastroesophageal reflux, abdominal pain, vomiting, and failure to thrive. Several otolaryngologic symptoms are associated with EoE including rhinosinusitis, chronic cough, recurrent croup, hoarseness, and other aerodigestive symptoms refractory to gastroesophageal reflux therapy. Eosinophilic esophagitis is also frequently associated with other atopic conditions, such as asthma, eczema, and food allergies. The diagnosis is made on endoscopy with biopsies that reveal eosinophil-predominant esophageal inflammation. There are 3 major treatment approaches to EoE, commonly referred to as the 3 Ds: diet, drugs, and dilation. Untreated inflammation of esophagus from EoE can result in irreversible structural damage to the esophagus, leading to fibrosis, strictures, and impaired esophageal function.

Conclusions and Relevance

Eosinophilic esophagitis is now a fairly prevalent condition with considerable morbidity. Otolaryngologists should be familiar with the various clinical presentations of this condition in different age groups. Early diagnosis and treatment of this condition is a key for avoiding or postponing its complications.

Eosinophilic oesophagitis: an otolaryngologist's perspective

Eosinophilic oesophagitis is a diagnosis that is being made more frequently in the assessment of dysphagia in both adults and children. It is unclear whether this is a result of increased prevalence or improved diagnostic methods. Children present commonly to paediatric institutions with foreign body impaction. Research indicates that food impaction may predispose to eosinophilic oesophagitis. This article presents eosinophilic oesophagitis from an otolaryngologist's point of view. It details the clinical features present in the disease as well as how it is diagnosed and managed. It illustrates early signs of eosinophilic oesophagitis so that primary physicians and emergency physicians know when to refer on to otolaryngologists.

Esophageal Food Impaction and Eosinophilic Esophagitis: A Retrospective Study, Systematic Review, and Meta-Analysis

BACKGROUND

Esophageal food impaction (EFI) can be the initial presentation of eosinophilic esophagitis (EoE). EoE is characterized by persistent esophageal eosinophilia (EE). Both EFI and EE are related to a variety of conditions. To date, the relationship between EFI, EE, and EoE remains unclear.

AIMS

To review our institutional experience with EFIs and combine our knowledge with the existing literature to conduct a systematic review and meta-analysis for delineating the relationship between EFI, EE, and EoE.

METHODS

We reviewed medical records of 72 children with EFI presenting to our emergency center between 2007 and 2013. PubMed, EMBASE, and Scopus databases were screened from inception until July 2014 to identify studies linking EFI and EoE. Included studies were methodically assessed for the quality and strength of association between EFI and EoE.

RESULTS

Our institutional experience highlighted the possibility of proton-pump inhibitor therapy-responsive EE (PPI-REE) as an underrecognized risk factor for EFI. A systematic review of 14 studies, including ours, revealed that most studies did not eliminate other causes of EFI or EE. The meta-analysis revealed that esophageal biopsies were obtained from 54% (40-68) of individuals presenting with EFI, and the overall EoE-attributable EFI among those who were biopsied was 54% (43-65). Substantial heterogeneity was noted among the studies.

DISCUSSION

PPI-REE is an underestimated risk factor for EFI. The quality of existing evidence linking EFI and EoE is limited by several important factors. Future studies with robust design are warranted to delineate the relationship between EFI, EE, and EoE.

Eosinophilic oesophagitis: a systematic review for otolaryngologists

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.

Extraction of esophageal foreign bodies in children: rigid versus flexible endoscopy

PURPOSE

Foreign body (FB) ingestion is a common and potentially serious problem in children. Both rigid (RE) and flexible (FE) endoscopic techniques are used for removal of esophageal FBs; however, there is no consensus amongst pediatric surgeons regarding the best method. This study reviewed our experience managing esophageal FBs using both techniques.

METHODS

A 12-year retrospective review of children admitted with an esophageal FB between 1999 and 2012 was undertaken. Clinical data, management techniques, and complications were abstracted. Differences between these two groups were compared with standard statistical methods.

RESULTS

657 children were treated for esophageal FB ingestion, of which 366 (56%) were treated with FE. The most frequently ingested item was a coin (84%), and FBs were most commonly lodged in the upper third of the esophagus (78%). There was a slightly younger population in the FE group (4.0 vs. 3.3 years, p < 0.01), but otherwise no significant differences were found between the groups. The FB was successfully removed with the initially chosen technique in 97% of patients.

CONCLUSIONS

Esophageal FBs may be successfully removed with either RE or FE. Since treatment failures were managed with conversion to the other technique, both procedures should be included in the training curriculum.
