Esophageal food impaction in children

Esophageal food bolus impaction in children: A 15-year experience and a review

OBJECTIVES

We aimed to analyze the episodes of esophageal food bolus impaction (EFI) occurred over a time of 15 years in children admitted to a large pediatric emergency department (PED), documenting their clinical presentation, underlying pathology, management, biopsy rate, and follow-up visits. Additionally, to combine our institutional experience with the existing literature, a comprehensive review was conducted.

METHODS

We reviewed the medical records of all children presenting to our PED with EFI from 2010 to 2024. The comprehensive review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement for systematic reviews. Electronic databases including PubMed/Medline and EMBASE were screened. The data obtained was synthesized to map out the actual status and current literature on pediatric EFI.

RESULTS

We identified 54 cases of EFI. Overall, 22 patients (41%) had underlying pathology. Previous episodes were reported in 14 cases (26%). Urgent endoscopy was performed in 31 cases (57%). The presence of underlying pathology was associated with the need for endoscopic removal (p = 0.013), as well as the history of previous episodes (p = 0.016). Biopsies were performed in 14 cases (26%). Pediatric gastroenterologists showed a higher rate of performed biopsies compared to surgeons, as well as higher rate of follow-up visits. An underlying disease was found during later clinical follow-up in 5 out of 54 cases of EFI (9%). A comprehensive review of 16 studies revealed high rates of underlying pathology and low rates of biopsies and follow-up visits among children with EFI.

CONCLUSION

Increased vigilance in identifying underlying pathologies in children with EFI is crucial. The importance of performing biopsies, regardless of prior anatomical conditions, and the need for ongoing follow-up to ensure timely and accurate diagnoses should be addressed through shared protocols.

Esophageal food bolus impaction in pediatric age

OBJECTIVES

Esophageal food impaction (EFI) is the sudden onset of dysphagia that occurs when a food bolus becomes lodged in the esophagus, requiring endoscopic removal. Scientific data on the prevalence and causes of EFI in children is lacking. The aim of this study was to provide further insights into EFI episodes in children.

METHODS

We have prospectively enrolled all children admitted for a first episode of EFI between March 2018 and March 2023. A fluoroscopic contrast study was performed in all patients to confirm the boluses and assess their position. Boluses were extracted by esophagogastroduodenoscopies, and esophageal biopsies were routinely obtained for histologic evaluation.

RESULTS

Over the study period, 41 children were admitted for a first episode of food impaction. Drooling was the most commonly reported symptom. Half children experiencing a first episode of food bolus were diagnosed with EoE (20/41, 48.8%). Almost a fourth of the episodes subtended a different condition, such as esophageal anastomotic, peptic or congenital strictures, stricturing caustic esophagitis, esophageal duplication, and achalasia. In the last fourth of patients the cause of EFI was not identified and thus probably related to quick eating and inadequate chewing of food.

DISCUSSION

Our study represents the largest known series of pediatric patients evaluated for food bolus impaction. Our main finding is the high frequency of EoE, which accounts for a half of EFI episodes in pediatric age, especially in older children. This finding highlights the importance of obtaining esophageal biopsies after the endoscopic bolus removal in children with EFI to provide a complete diagnostic evaluation.

Ask Doctor Smartphone! An App to Help Physicians Manage Foreign Body Ingestions in Children

BACKGROUND

Foreign body ingestion (FBI) represents the most common cause of emergent gastrointestinal endoscopy in children. FBI's management can be quite challenging for physicians because of the variability of the clinical presentation, and the decision tree becomes even more intricate because of patient-specific variables that must be considered in the pediatric age range (e.g., age of patients and neuropsychiatric disorders) in addition to the mere characteristics of the foreign body. We present an application for smartphones designed for pediatricians and pediatric surgeons based on the latest guidelines from the official pediatric societies. The app aims to help physicians manage FBI quickly and properly in children.

MATERIALS AND METHODS

The latest pediatric FBI management guidelines were reviewed and summarized. The flow chart we obtained guided the development of a smartphone application. A questionnaire was administered to all pediatric surgeon trainees at our institute to test the feasibility and helpfulness of the application.

RESULTS

An app for smartphones was obtained and shared for free on the Google Play Store and Apple Store. The app guides the physician step by step in the diagnostic process, analyzing all patient- and foreign body-specific characteristics. The app consultation ends with a suggestion of the most proper decision to make in terms of further radiological investigations and the indication and timing of endoscopy. A questionnaire administered to trainees proved the app to be useful and easy to use.

CONCLUSION

We developed an app able to help pediatricians and pediatric surgeons manage FBI in children, providing standardized and updated recommendations in a smart and easily available way.

Pediatric Foreign Body Ingestion: Complications and Patient and Foreign Body Factors

Background: Management of the child who has swallowed a foreign body should be guided by the risk of complication. Objective of the Review: This review discusses the patient and foreign body characteristics most likely to be associated with complications. Discussion: Most swallowed foreign bodies will pass through the GI tract without complication. Children with pre-existing GI tract abnormalities of any sort, or those who swallow higher-risk foreign bodies, are at higher risk. Higher-risk foreign bodies include long, sharp, or pointed objects, button batteries, and small magnets. Nearly any child who presents to an Emergency Department or other acute care setting after foreign body ingestion should undergo plain radiography; other forms of imaging may also be appropriate. Primary care providers may opt for an initial observation period when there is lower risk of complication. Esophageal button batteries should be emergently removed; other esophageal objects should be promptly removed or, if low risk, allowed a brief period to pass spontaneously. Most lower GI tract foreign bodies will pass spontaneously. Prevention, while not always possible, is preferable to management of foreign body ingestion. Conclusions: Management strategies for children who have swallowed foreign bodies can be optimized by considering relevant patient and foreign body factors, and how they contribute to the risk of complication.

Inpatient Pediatric Foreign Body Ingestion: National Estimates and Resource Utilization

OBJECTIVE

We generated national estimates of patient and hospitalization characteristics for pediatric inpatient admissions for foreign body ingestion (FBI) and compared these to admissions for other reasons. We further identified characteristics that were independently associated with length of stay (LOS). Finally, we hypothesized that endoscopy within 24 hours of admission was independently associated with a shorter LOS in patients admitted for FBI.

METHODS

In this retrospective study, we used data from the Kids' Inpatient Database for 2016. Admissions for FBI were identified and national estimates of patient and hospitalization characteristics were generated. Patients admitted for FBI were compared to patients admitted for other causes. Data were analyzed for independent associations with LOS. Subgroup analysis was performed to determine whether early endoscopy was associated with a shorter LOS.

RESULTS

A total of 2464 admissions for FBI were identified in the database. The median (interquartile range) patient age was 4 (1-11) years with a slight male predominance. Most patients (82.6%) had an endoscopy performed during admission. Independent factors associated with increased LOS included: airway procedures, intra-abdominal surgery, psychiatric diagnosis, esophageal disorder, and developmental delay. Among patients who required endoscopy, 56.7% were performed early (within 24 hours). Early endoscopy was independently associated with a 35% shorter LOS (incidence rate ratio = 0.65, 95% confidence interval 0.54-0.80; P=0.009).

CONCLUSIONS

Inpatient admissions for FBI frequently require endoscopy and have a short LOS. In patients who require endoscopy during the admission, early endoscopy (within 24 hours of admission) may be associated with a shorter LOS.

Pediatric Esophageal Foreign Body: Possible Role for Digital Tomosynthesis

OBJECTIVES

Foreign body (FB) ingestion is a common reason for emergency department visits, affecting more than 80,000 children in the United States annually. Whereas most ingested FBs are coins or other radiopaque objects, some are radiolucent FBs such as food. Digital tomosynthesis (DTS) is a radiographic technique that produces cross-sectional images with in-plane resolution similar to that of traditional radiographs. Our pilot study evaluated the sensitivity and specificity of DTS to detect FB in comparison to esophagram and clinical impression.

METHODS

This was a retrospective review on patients aged 0 to 18 years with suspected esophageal FB who received an esophagram with DTS at our institution between January 2014 and June 2016. Digital tomosynthesis images were analyzed by 3 readers for identification of FB impaction and compared with esophagram and discharge diagnosis. This study was approved by our local institutional review board.

RESULTS

A total of 17 patients underwent an esophagography with DTS for suspected esophageal FB, of which 9 (53%) were suspected of having an FB on esophagram. Compared with esophagram, DTS had a sensitivity of 44%, specificity of 100%, positive predictive value of 100%, and negative predictive value of 62%. Compared with clinical impression, DTS had a sensitivity of 33%, specificity of 100%, positive predictive value of 100%, and negative predictive value of 38%.

CONCLUSIONS

This pilot study showed that chest DTS has a very high positive predictive value, compared with esophagram and clinical impression, in detecting radiolucent esophageal FBs in children. Chest DTS is a promising modality for ruling in the presence of a radiolucent esophageal FB.

Foreign body and caustic ingestions in children: A clinical practice guideline

Foreign body and caustic ingestions in children are usually the most common clinical challenges for emergency physicians, general pediatricians and pediatric gastroenterologists. Management of these conditions often requires different levels of expertise and competence. Endoscopy is often necessary but there is a high risk of misusing this tool with incorrect timing and indications. The imprecise clinical history frequently leaves clinicians uncertain about timing and nature of the ingestion. Few clinical guidelines regarding management of these ingestions in children have been published, none of which from the Italian Society of Pediatric Gastroenterology, Hepatology and Nutrition (SIGENP). An expert panel of Italian endoscopists was convened by the SIGENP Endoscopy Working Group to produce the present article that outlines practical clinical approaches to the pediatric patient with a variety of foreign body and caustic ingestions. The Italian Association of Hospital Gastroenterologists and Endoscopists (AIGO) has also endorsed the project since many adult endoscopists usually manage children with these conditions. Differently from the other published guidelines, the proposed one focuses on the role of the endoscopists (regardless of whether they are adult or pediatric gastroenterologists) in the diagnostic process of children with foreign body and caustic ingestions.

Congenital esophageal stenosis: a rare malformation of the foregut

Congenital esophageal stenosis (CES) is a type of esophageal stenosis, and three histological subtypes (tracheobronchial remnants, fibromuscular thickening or fibromuscular stenosis, and membranous webbing or esophageal membrane) are described. Symptoms of CES usually appears with the introduction of the semisolid alimentation. Dysphagia is the most common symptom, but esophageal food impaction, respiratory distress or failure to thrive can be clinical manifestations of CES. Wide spectrum of differential diagnoses leads to delayed definitive diagnosis and appropriate treatment. Depends on hystological subtype of CES, some treatment procedures (dilation or segmental esophageal resection) are recommended, but individually approach is still important in terms of frequency and type of dilation procedures or type of the surgical treatment. Dysphagia can persist after the treatment and a long follow-up period is recommended. In 33% of patients with CES, a different malformations in the digestive system, but also in the other systems, are described.

Esophageal Foreign Bodies and Obstruction in the Emergency Department Setting: An Evidence-Based Review

BACKGROUND

Patients with esophageal foreign bodies or food bolus impaction may present to the emergency department with symptoms ranging from mild discomfort to severe distress. There is a dearth of emergency medicine-focused literature concerning these conditions.

OBJECTIVE OF THE REVIEW

This narrative review provides evidence-based recommendations for the assessment and management of patients with esophageal foreign bodies and food bolus impactions.

DISCUSSION

Esophageal foreign bodies and food bolus impaction are common but typically pass spontaneously; however, complete obstruction can lead to inability to tolerate secretions, airway compromise, and death. Pediatric patients are the most common population affected, while in adults, edentulous patients are at greatest risk. Foreign body obstruction and food bolus impaction typically occur at sites of narrowing due to underlying esophageal pathology. Diagnosis is based on history and examination, with most patients presenting with choking/gagging, vomiting, and dysphagia/odynophagia. The preferred test is a plain chest radiograph, although this is not required if the clinician suspects non-bony food bolus with no suspicion of perforation. Computed tomography is recommended if radiograph is limited or there are concerns for perforation. Management requires initial assessment of the patient's airway. Medications evaluated include effervescent agents, glucagon, calcium channel blockers, benzodiazepines, nitrates, and others, but their efficacy is poor. Before administration, shared decision making with the patient is recommended. Endoscopy is the intervention of choice, and medications should not delay endoscopy. Early endoscopy for complete obstruction is associated with improved outcomes.

CONCLUSIONS

This review provides evidence-based recommendations concerning these conditions, focusing on evaluation and management.

Management of Esophageal Food Impaction Varies Among Gastroenterologists and Affects Identification of Eosinophilic Esophagitis

BACKGROUND AND AIMS

Esophageal food impaction (EFI) is a gastrointestinal emergency requiring immediate evaluation in the emergency room (ER) and an esophagogastroduodenoscopy (EGD) for disimpaction. EFI is also a distinct presenting feature of eosinophilic esophagitis (EoE). This study aimed at understanding the management of EFI among gastroenterologists (GIs) and estimated its impact on identification of EoE in USA.

METHODS

GIs associated with three major gastroenterology societies based in USA were invited to participate in a web-based survey. Information on the resources available and utilized, and the clinical decision-making process related to management of EFI cases was collected and analyzed.

RESULTS

Of 428 responses, 49% were from pediatric GIs, 86% practiced in the USA, and 78% practiced in an academic setting. Compared to the pediatric GIs, adult GIs were more likely to perform EGD in the emergency room [OR 87.96 (25.43-304.16)] and advance the food bolus into stomach [5.58 (3.08-10.12)]. Only 34% of respondents obtained esophageal biopsies during EGD, and pediatric GIs were more likely to obtain esophageal biopsies [3.49 (1.12-10.84)] compared to adult GIs. In USA, by our conservative estimates, 10,494 patients presenting to ER with EFI and at risk of EoE are likely being missed each year.

CONCLUSIONS

EFI management varies substantially among GIs associated with three major gastroenterology societies in USA. Based on their practice patterns, the GIs in USA are likely to miss numerous EoE patients presenting to ER with EFI. Our findings highlight the need for developing and disseminating evidence-based EFI management practice guidelines.

Association between Eosinophilic Esophagitis and Esophageal Food Impaction in the Pediatric Population

Objectives (1) To describe the presentation, management, and outcomes associated with pediatric esophageal food impaction (EFI) at a single tertiary care institution. (2) To identify the key clinical features of pediatric EFI that are associated with a diagnosis of eosinophilic esophagitis (EoE). Study Design Case series with chart review. Setting Tertiary care children's hospital. Subjects and Methods Thirty-five children <18 years of age presenting with EFI between November 1, 2006, and October 31, 2013, were included. Presenting symptoms, medical history, biopsy results, endoscopic findings, and underlying etiology were examined. Fisher exact test, t tests, and logistic regression were used to compare between patients with and without EoE. Results Thirty-five patients had isolated EFI and were included in the study. EoE accounted for 74% (n = 26) of pediatric EFI, with the remaining cases being attributed to neurologic impairment (n = 5, 15%), prior surgeries (n = 1, 3%), reflux esophagitis (n = 1, 3%), or unknown etiologies (n = 2, 6%). EFI was the initial manifestation of EoE in 81% (n = 21) of patients. The most common presenting symptoms were dysphagia (n = 34), choking (n = 26), and vomiting (n = 23). Linear furrowing was the only endoscopic finding that was significantly associated with EoE ( P < .001). Conclusion Most esophageal food impactions in the pediatric population are associated with an underlying diagnosis of EoE and are often the initial manifestation of the disease. EoE must be considered in all pediatric patients with EFI; esophageal biopsies should be strongly considered in these patients at the time of endoscopic management of the EFI.

Movement Disorder Associated With Foreign Body Ingestion

We present a case of recurrent bouts of irritability with arching, head extension, and lethargy in a previously healthy 10-month-old girl admitted to the PICU for acute onset of a movement disorder. The patient's vital signs and physical examination were unremarkable but recurrent bouts of abnormal movements persisted for the first 10 hours of admission in the PICU. Possible diagnoses, such as meningitis, status epilepticus, space occupying lesions, and toxic ingestions, were ruled out because of negative cerebrospinal fluid analysis, normal EEG, and negative results of other ancillary tests. On the second day of admission, an abdominal radiograph was obtained because intussusception was considered a probable diagnosis due to recurrent episodes of arching and lethargy. The abdominal radiograph revealed the presence of a 15-mm radiopaque foreign body in the right lower quadrant corresponding to the anatomic location of the ileocecal valve. The patient made an uneventful recovery after she spontaneously passed a 1.5 cm by 1 cm rock (15 mm) in her stool on the third day of admission. This case highlights the need for a high index of suspicion for unwitnessed ingestion of a foreign body in a previously healthy preschool child with sudden onset of a movement disorder.

Paediatric Gastrointestinal Endoscopy: European Society for Paediatric Gastroenterology Hepatology and Nutrition and European Society of Gastrointestinal Endoscopy Guidelines

This guideline refers to infants, children, and adolescents ages 0 to 18 years. The areas covered include indications for diagnostic and therapeutic esophagogastroduodenoscopy and ileocolonoscopy; endoscopy for foreign body ingestion; corrosive ingestion and stricture/stenosis endoscopic management; upper and lower gastrointestinal bleeding; endoscopic retrograde cholangiopancreatography; and endoscopic ultrasonography. Percutaneous endoscopic gastrostomy and endoscopy specific to inflammatory bowel disease has been dealt with in other guidelines and are therefore not mentioned in this guideline. Training and ongoing skill maintenance are to be dealt with in an imminent sister publication to this.

Western view of the management of gastroesophageal foreign bodies

The best modality for foreign body removal has been the subject of much controversy over the years. We have read with great interest the recent article by Souza Aguiar Municipal Hospital, Rio de Janeiro, Brazil, describing their experience with the management of esophageal foreign bodies in children. Non-endoscopic methods of removing foreign bodies (such as a Foley catheter guided or not by fluoroscopy) have been successfully used at this center. These methods could be an attractive option because of the following advantages: Shorter hospitalization time; easy to perform; no need for anesthesia; avoids esophagoscopy; and lower costs. However, the complications of these procedures can be severe and potentially fatal if not performed correctly, such as bronchoaspiration, perforation, and acute airway obstruction. In addition, it has some disadvantages, such as the inability to directly view the esophagus and the inability to always retrieve foreign bodies. Therefore, in Western countries clinical practice usually recommends endoscopic removal of foreign bodies under direct vision and with airway protection whenever possible.

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.

Congenital esophageal stenosis diagnosed in an infant at 9 month of age

Esophageal stenosis is a relatively uncommon condition in pediatrics and requires an accurate diagnostic approach. Here we report the case of a 9-month old female infant who presented intermittent vomiting, dysphagia and refusal of solid foods starting after weaning. She was treated for gastroesophageal reflux. At first, radiological investigation suggested achalasia, while esophagoscopy revelaed a severe congenital esophageal stenosis at the distal third of the esophagus. She underwent four endoscopic balloon dilatations that then allowed her to swallow solid food with intermittent mild dysphagia. After 17 months of esomeprazole treatment off therapy impedance-pH monitoring was normal. At 29 months of follow-up the child is asymptomatic and eats without problems.Infants with dysphagia and refusal of solid foods may have undiagnosed medical conditions that need treatment. Many disorders can cause esophageal luminal stricture; in the pediatric age the most common are peptic or congenital. Careful assessment with endoscopy is needed to diagnose these conditions early and referral to a pediatric gastroenterologic unit may be necessary.

Management of ingested foreign bodies in children: a clinical report of the NASPGHAN Endoscopy Committee

Foreign body ingestions in children are some of the most challenging clinical scenarios facing pediatric gastroenterologists. Determining the indications and timing for intervention requires assessment of patient size, type of object ingested, location, clinical symptoms, time since ingestion, and myriad other factors. Often the easiest and least anxiety-producing decision is the one to proceed to endoscopic removal, instead of observation alone. Because of variability in pediatric patient size, there are less firm guidelines available to determine which type of object will safely pass, as opposed to the clearer guidelines in the adult population. In addition, the imprecise nature of the histories often leaves the clinician to question the timing and nature of the ingestion. Furthermore, changes in the types of ingestions encountered, specifically button batteries and high-powered magnet ingestions, create an even greater potential for severe morbidity and mortality among children. As a result, clinical guidelines regarding management of these ingestions in children remain varied and sporadic, with little in the way of prospective data to guide their development. An expert panel of pediatric endoscopists was convened and produced the present article that outlines practical clinical approaches to the pediatric patient with a variety of foreign body ingestions. This guideline is intended as an educational tool that may help inform pediatric endoscopists in managing foreign body ingestions in children. Medical decision making, however, remains a complex process requiring integration of clinical data beyond the scope of these guidelines. These guidelines should therefore not be considered to be a rule or to be establishing a legal standard of care. Caregivers may well choose a course of action outside of those represented in these guidelines because of specific patient circumstances. Furthermore, additional clinical studies may be necessary to clarify aspects based on expert opinion instead of published data. Thus, these guidelines may be revised as needed to account for new data, changes in clinical practice, or availability of new technology.

Updates in pediatric gastrointestinal foreign bodies

Although most ingested foreign bodies in children pass spontaneously, certain foreign bodies can be harmful and they require special attention and emergent medical intervention to prevent significant morbidity and mortality. This article presents an overview of the epidemiology, diagnosis, management, and complications of foreign body ingestions in children. Particular attention is paid to coins, sharp objects, long objects, food bolus, caustic liquids, batteries, and magnets.

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

BACKGROUND

Esophageal foreign body impaction (EFBI) is a common problem requiring urgent endoscopy. EFBI may be the first sign of underlying esophageal pathology, yet mucosal biopsies are rarely performed.

METHODS

We report a retrospective analysis of 572 children requiring removal of an EFBI over a 12-year period by pediatric otolaryngologists (ENT), surgeons (PS), and gastroenterologists (PGI). The method of removal [direct laryngoscopy (DL), rigid endoscopy (RE), flexible endoscopy (FE)], type of foreign body (inanimate or food), whether mucosal biopsies were performed, and histologic findings of biopsy samples were recorded for each patient.

RESULTS

Foreign body removal was most commonly performed by PGI (298 [52 %]); the remaining were equally distributed between ENT (136 [24 %]) and PS (138 [24 %]). The method of foreign body removal used by ENT was RE (89 %), DL (8 %), and FE (3 %). Pediatric surgery preferred FE (62 %), followed by RE (27 %) and DL (11 %). Pediatric gastroenterology used FE exclusively. Esophageal biopsies were never performed by ENT or PS; PGI performed esophageal biopsies more commonly in children with meat bolus impactions (50 %) than in children with inanimate foreign bodies (12 %). Mucosal pathology was more common in children with meat bolus impaction (100 %) than in children with inanimate foreign bodies (45 %).

CONCLUSIONS

Esophageal mucosal biopsy should be considered for all children with EFBI not attributed to stricture, particularly those with meat bolus impaction.

Fluoroscopic findings in pediatric eosinophilic esophagitis

BACKGROUND

Eosinophilic esophagitis (EE) is an inflammatory disorder of the esophagus characterized by symptoms such as dysphagia, food sticking and heartburn. Several fluoroscopic findings have been described in EE, but the frequency of these findings is unknown.

OBJECTIVE

To identify the frequency of imaging findings in pediatric-age patients with eosinophilic esophagitis.

MATERIALS AND METHODS

A retrospective study was performed evaluating all upper GI and esophagram studies performed between 2000 and 2008 in patients up to age 21 with a pathological diagnosis of EE. In order to be included in the study, the upper GI or esophagram had to be performed either before EE was diagnosed or within 30 days of the diagnosis. Two pediatric radiologists evaluated each study for the presence or absence of multiple findings of EE. The radiology reports from the time of the study were then read to establish a concurrent diagnosis of esophageal dysmotility or gastroesophageal reflux. Finally, the hospital electronic medical record was evaluated to obtain demographic and pathology information.

RESULTS

Of the 579 patients with biopsy-proven EE, 107 (18%) were included in the study and underwent a total of 112 upper GI or esophagram examinations. The most common finding on these examinations was a normal esophagus (58/112; 52%) followed by gastroesophageal reflux (21/112; 19%) and irregular contractions (17/112; 15%). Less frequent findings included strictures, dysmotility, mucosal irregularity, esophageal rings and filling defects.

CONCLUSION

Fluoroscopic studies are not a sensitive method to diagnose EE because nearly half of the studies are normal. Findings that have been described in the setting of EE such as food impaction, a ringed esophagus, a small-caliber esophagus and esophageal stricture do not occur with a high enough frequency to reliably make a diagnosis.

Epidemiology and management of oesophageal coin impaction in children

OBJECTIVE

The epidemiology of oesophageal coin impaction in children is poorly understood. We aimed to assess characteristics of patients with coin impaction and identify predictors of type of coin impacted and management strategies.

METHODS

Cases of coin impaction from 2002 to 2009 were identified by querying a tertiary care centre's billing, clinical, and endoscopy databases for the International Classification of Diseases, 9th Revision code "935.1 - foreign body in the oesophagus." Charts were reviewed to confirm case status and to extract pertinent data.

RESULTS

Of 113 patients with oesophageal coin impaction (55% male; 45% Caucasian; mean age 2.9 years), 65 (58%) swallowed a penny, 85 (80%) had the impaction in the proximal oesophagus, and 103 (91%) required a procedure. Thirty-five (34%) patients had an upper endoscopy performed by a gastroenterologist and 68 (66%) had a laryngoscopy or oesophagoscopy performed by an otolaryngologist. Only 2 minor complications were noted. There was no significant relationship between the coin type and location of impaction, but 99% of cases performed by otolaryngologists were for proximally impacted coins, compared to 49% for gastroenterologists (p<0.001).

CONCLUSIONS

Oesophageal coin impaction disproportionately affected young children and extraction was frequently required. Whilst pennies were the most commonly impacted coin, there were no clear predictors on impaction based on coin type.

Foreign bodies in the airways: a meta-analysis of published papers

BACKGROUND

Very recently, some attempts have been made to start a systematic collection of foreign bodies (FB) in view of using them to characterize the risk of chocking in terms of size, shape and consistency of the FB. However, most of the epidemiologic evidence on foreign bodies in children comes from single-center retrospective studies, without any systematic geographical and temporal coverage. This paper is aimed at providing an estimate of the distribution of foreign body's injuries in children according to gender, age, type of FB, site of obstruction, clinical presentation, diagnostic/therapeutic procedures, complications, as emerging from a meta-analytic review of published papers.

METHODS

A free text search on PubMed database ((foreign bodies) OR (foreign body)) AND ((aspiration) OR (airways) OR (tracheobronchial) OR (nasal) OR (inhalation) OR (obstruction) OR (choking) OR (inhaled) OR (aspirations) OR (nose) OR (throat) OR (asphyxiation)) AND ((children) OR (child)) finalized to identify all English written articles referring to foreign body inhalation over a 30 years period (1978-2008) was performed. The target of the analysis has been defined as the proportion of injuries as reported in the studies, stratified according to children demographic characteristics, type of FB, site of obstruction. The pooled proportions of FB were calculated using the DerSimonian and Laird approach.

RESULTS

1699 papers were retrieved and 1063 were judged pertinent; 214 English written case series were identified, among them 174 articles were available and have been included in the analysis. Airway foreign body most commonly occurs in young children, almost 20% of children who have inhaled foreign bodies being between 0 and 3 years of age. Organic FB, particularly nuts, are the most documented objects while, among inorganic FBs, the greatest pooled proportion has been recorded for magnets, which can be particularly destructive in each location. Non specific symptoms or a complete absence of symptoms are not unusual, justifying mistaken or delayed diagnosis. Acute and chronic complications seem to occur in almost 15% of patients.

CONCLUSIONS

Even if an enormous heterogeneity among primary studies seems to exist and even if the absence of variables standardized definitions across case series, including class age definition and symptoms and signs descriptions, seriously impairs studies comparability, our results testify the relevant morbidity associated with foreign body inhalation in children, stressing the importance of preventive measures.

Causes of esophageal food bolus impaction in the pediatric population

BACKGROUND

Esophageal food bolus impaction is an uncommon entity in the pediatric population that presents with the acute onset of dysphagia, pain, and vomiting. The causes of esophageal food bolus impaction are thought to be different in the pediatric population as compared to adults.

AIM

The purpose of this study was to determine the frequency of the different causes of food impaction in patients who undergo an esophagram or upper GI examination.

METHODS

The radiology report database was searched to identify all patients with an esophageal food bolus impaction diagnosed on upper GI or esophagram between 1993 and 2009. Two pediatric radiologists then evaluated each esophagram to determine the location of the filling defect within the esophagus. Finally, the electronic medical record was queried to identify demographic information and abnormalities associated with the food impaction.

RESULTS

After querying the radiology database, 43 patients were identified with an impacted food bolus on esophagram or upper GI. There were three abnormalities associated with food impaction: eosinophilic esophagitis (23/43; 53%), prior esophageal atresia repair (11/43; 26%), and prior Nissen fundoplication (5/43; 12%). There were eight patients in whom no underlying abnormality was identified.

CONCLUSIONS

Eosinophilic esophagitis is the major abnormality associated with food bolus impaction in pediatric patients followed by narrowing at the site of prior esophageal or esophageal-related surgery.

Etiology of esophageal food impactions in children

OBJECTIVE

The aim of the study was to measure clinicopathological features of children presenting to a tertiary care emergency department with esophageal food impaction.

MATERIALS AND METHODS

A retrospective chart review of children with esophageal food impaction seen between January 1, 2005 and June 30, 2009, including all patients from age 1 month to 18 years with esophageal food impaction at a pediatric emergency department, was performed.

RESULTS

Initial screening of International Classification of Disease, 9th Revision, discharge diagnosis identified 698 children with an esophageal foreign body. Of this group, 72 esophageal food impaction events were identified in 65 children (69% boys), 49 of whom required endoscopic intervention. Endoscopic appearances of the esophageal mucosa were abnormal in 40 (82%), revealing evidence of esophagitis (55%) or stricture (27%). Twenty-four of the subjects had biopsies taken at the time of endoscopy. Inflammation, described as increased eosinophils, basilar hyperplasia, rete peg elongation, and/or microabscess, was present in 76% of mucosal samples. Follow-up endoscopy in 12 children identified an etiology in 9, five of whom were found to have eosinophilic esophagitis.

CONCLUSIONS

The majority of children with esophageal food impaction who underwent endoscopic evaluation and biopsy have an underlying potentially treatable cause. We therefore recommend that all of the children with esophageal food impaction have mucosal biopsies at the time of endoscopic disimpaction with appropriate follow-up to allow for diagnosis and management of the underlying etiology.

Successful treatment of congenital esophageal web by endoscopic electrocauterization and balloon dilatation

We report a 3-year-old boy who presented with a foreign body impacted in the esophagus and had a poor tolerance of solid food since he was 5 to 6 months old. In the last 2 years, he developed progressive dysphagia, anorexia, vomiting, and poor weight gain. An esophagoscopy and barium esophagogram revealed an esophageal web in the distal third of the esophagus. Three courses of endoscopic balloon dilatation resulted in transient improvement in his dysphagia and vomiting; a follow-up barium esophagogram and esophagoscopy showed limited improvement of the esophageal stenosis. Two courses of endoscopic electrocauterization and balloon dilatation improved the clinical symptoms and esophageal stenosis.

Deaths due to choking in Prader-Willi syndrome

Prader-Willi syndrome (PWS) is the most common known syndromic cause of life-threatening obesity, yet few studies have examined the causes of death in PWS. The objective of this study was to examine the contribution of choking leading to mortality in PWS. In 1999, a brief survey was made available from the Prader-Willi Syndrome Association (USA) bereavement program, which documented demographic data and causes of death. Families were subsequently offered the opportunity to fill out a detailed questionnaire and additional forms to release medical records. Demographic information was available on 178 deceased individuals with PWS, and cause of death available on 152 individuals. Fifty-four families completed questionnaires. Of the deceased individuals with completed questionnaires, 34% reported a history of choking. Choking was listed by familial report as the cause of death in 12 (7.9%) of 152 subjects with an average age of 24 years (range 3-52 years; median 22.5 years) at death from choking. Only two of these individuals were less than 8 years of age. The data suggest that risks associated with choking are different in the PWS population compared with others. Potential causes of increased choking in PWS include poor oral/motor coordination, poor gag reflex, hypotonia, hyperphagia, decreased mastication, and voracious feeding habits. We recommend implementation of preventive measures and education for families and group home care providers for all individuals with PWS including the Heimlich maneuver, supervised meals, better food preparation, and diet modification to avoid high-risk choking items.

Removal of impacted food in children with eosinophilic esophagitis using Saeed banding device

Food impaction in patients with eosinophilic esophagitis is being recognized increasingly. Retrieval of impacted food may be necessary if it does not resolve spontaneously. The present report describes a new technique for removal of friable impacted food from the esophagus using a modified version of the Saeed banding device. With this technique, impacted food was safely removed in a single attempt in each of 3 patients.

Endoscopic techniques and management of foreign body ingestion and food bolus impaction in the upper gastrointestinal tract: a retrospective analysis of 139 cases

BACKGROUND

Ingested foreign bodies and food bolus impaction are frequently seen in endoscopic practice. Successful foreign body and food bolus removal may depend on the method used, the choice of device, and the experience level of the endoscopist, although few papers report experience and outcome of tertiary centers.

AIM

To investigate the effectiveness of our protocol designed for removal of ingested foreign bodies and food boluses.

METHODS

We retrospectively reviewed all patients with a diagnosis of foreign body ingestion and food bolus impaction from 1994 to 2005 identified by computer search. Patients were excluded if medical record was incomplete.

RESULTS

The analysis included 171 patients. Foreign bodies and impacted food boluses were found in 77 and 62 patients, respectively. In 32 cases (23%), the foreign bodies passed spontaneously through the gastrointestinal tract. The overall success rate for endoscopic management was obtained in 137 patients (98.6%). Surgical removal of a foreign body was required in only 2 cases (1.4%). According to the type and location of the foreign object and food bolus we used Dormia baskets, retrieval forceps, polypectomy snares, and all sizes of Roth net. No complications relating to the endoscopic procedure were observed; 50 patients (35.2%) had an underlying esophageal disease.

CONCLUSIONS

Endoscopic removal of upper gastrointestinal tract foreign bodies and food bolus impaction is efficacious and safe. Especially the Roth net is the best device for safe retrieval of food boluses and button disc batteries.

Pediatric foreign bodies and their management

Ingestion of foreign bodies is a common pediatric problem, with more than 100,000 cases occurring each year. The vast majority of pediatric ingestions are accidental; increasing incidence of intentional ingestions starts in the adolescent age group. In the United States, the most common pediatric foreign bodies ingested are coins, followed by a variety of other objects, including toys, toy parts, sharp objects, batteries, bones, and food. In adolescents and adults, meat or food impactions are the most common accidental foreign body ingestion. Esophageal pathology underlies most cases of food impaction. Management of foreign body ingestions varies based on the object ingested, its location, and the patient's age and size. Esophageal foreign bodies as a group require early intervention because of their potential to cause respiratory symptoms and complications, esophageal erosions, or even an aortoesophageal fistula. Ingested batteries that lodge in the esophagus require urgent endoscopic removal even in the asymptomatic patient due to the high risk of complications. Sharp foreign bodies increase the foreign body complication rate from less than 1% to 15% to 35%, except for straight pins, which usually follow a relatively benign course unless multiple pins are ingested. Magnets are increasingly ingested, due to their ubiquitous nature and the perception that they do not pose a risk. Ingestion of multiple magnets creates a significant risk of obstruction, perforation, and fistula development. Methods to deal with foreign bodies include the suture technique, the double snare technique, and the combined forceps/snare technique for long, large, and sharp foreign bodies, along with newer equipment, such as retrieval nets and a variety of specialized forceps.

Association of eosinophilic inflammation with esophageal food impaction in adults

INTRODUCTION

Esophageal food impaction is a common presentation of eosinophilic esophagitis. The prevalence of eosinophilic esophagitis among patients with food impaction is unknown. To address this, we evaluated clinicopathologic features of adults with food impaction.

METHODS

For a 3-year period, patients from a single, adult, community-based gastroenterology practice with esophageal food impaction were evaluated. Histories were assessed and esophageal biopsy specimens were evaluated by routine and immunohistochemical techniques.

RESULTS

Thirty-one patients with food impaction were evaluated. Seventeen of 31 patients had >20 eosinophils/high power field (HPF) without gender predilection. Thirteen of these 17 patients had been treated with proton pump inhibitors at the time biopsy specimens were obtained. Patients with >20 eosinophils/HPF were significantly younger (mean age 42 +/- 4 years) than patients with <20 eosinophils/HPF (mean age 70 + 3 years). Superficial white exudates and eosinophilic microabscesses in the squamous epithelium were features observed only in patients with >20 eosinophils/HPF. Immunopathologic analysis demonstrated increased CD8 lymphocytes and major basic protein deposition in their squamous epithelium.

CONCLUSIONS

More than half of patients with esophageal food impaction in a primary gastroenterology practice have >20 eosinophils/HPF. Based on clinicopathologic features, a significant number likely have eosinophilic esophagitis.

Imaging of the Esophagus in Children

The main role of the esophagus is to facilitate passage of food from the mouth to the stomach. A number of conditions can alter esophageal structure or function including congenital anomalies, trauma, infection, and neoplasm. This article reviews the anatomy, imaging evaluation, and common problems seen in the pediatric thoracic esophagus.
