A2 Years Old Boy with Recurrent Tracheoesophageal Fistula After Surgical Removal of an Esophageal Button Battery.

BACKGROUND Among the pediatric population, button batteries ingestion is a significant health risk. The main treatment of ingested esophageal button batteries is urgent endoscopic removal. Missed or delayed diagnosis results in serious complications and outcomes. In the literature, high morbidity and mortality have been described in cases of button battery ingestion. By reporting this case we aim to encourage physicians to raise their suspicion of foreign body ingestion in similar pediatric cases and to review the different management approaches in the case of foreign body-induced tracheoesophageal fistula. CASE REPORT A 2-year-old boy was referred to us with difficulty in swallowing solids and liquids, with tactile fever for 1 month. A chest X-ray showed a radiopaque foreign body consistent with a button battery. The battery was removed through surgical cervical incision followed by closure of an identified tracheoesophageal fistula, cervical loop esophagostomy, and gastrostomy. After 6 months of follow-up and gastrostomy feeding, recurrence of the tracheoesophageal fistula was identified, for which surgical closure and esophageal anastomosis were performed. A postoperative esophagogram done on day 7 showed no leak or evidence of tracheoesophageal fistula; the patient started oral feeding and the gastrostomy tube was removed. CONCLUSIONS Even in the absence of witnessed ingestion, the persistent nonspecific symptoms must raise the suspicion of foreign body ingestion in the pediatric age group. Failure of endoscopic removal of the battery is a possibility that need to be included in management algorithms. Surgical repair is the most frequently described approach for foreign body-induced tracheoesophageal fistula repair.

Vascular Complications in Children Following Button Battery Ingestions: A Systematic Review.

CONTEXT: Children presenting to health care facilities with button battery (BB) impaction. OBJECTIVES: To describe characteristics of children with vascular complications after BB impaction, as well as associated outcomes. DATA SOURCES: National Capital Poison Center registry and PubMed database from inception to December 2021. STUDY SELECTION: All reports describing children aged <18 years with vascular, esophageal, or airway complications after BB ingestion. DATA EXTRACTION: We extracted characteristics including date of publication, age and sex of child, battery type and size, duration and location of impaction, complications, subsequent interventions, and interval between battery removal and death. RESULTS: A total of 361 cases involved severe complications or death after BB ingestion (321 cases from the National Capital Poison Center registry database, 40 additional cases from PubMed). Nineteen percent (69 of 361) were fatal and 14% (51 of 361) involved vascular injuries. Three-quarters (75%) of vascular complications were aorto-esophageal fistulae and 82% of vascular injuries were not survivable. Fatal vascular cases had significantly longer median impaction time (96 hours versus 144 hours, P <.05) and a wider range of presenting features than survivors. LIMITATIONS: The total number of cases with vascular complications was small, data reported varied between cases, and no data were available on overall exposure. Long-term morbidity data were not available for the survivors. CONCLUSIONS: Prolonged BB impaction is a risk factor for vascular complications and death. A high index of suspicion is required for children representing with hematemesis after BB impaction, with prompt transfer to a tertiary center because vascular surgical intervention may offer a chance of survival.

Button battery injury: An update.

BACKGROUND: Paediatric button battery injuries present a challenge in the general practice setting. Although some children present with history or parental suspicion of button battery ingestion (BBI) or insertion, unwitnessed cases may present with non-specific symptoms that can mimic many respiratory and gastrointestinal pathologies. OBJECTIVE: The aim of this article is to increase awareness of the fast onset of life-threatening tissue injury from BBI and the importance of timely referral as well as provide an update on current management, including first aid management in the general practice setting. DISCUSSION: BBI is a medical emergency. The button battery requires urgent removal as it can cause caustic burn injury to its surrounding tissues in as little as 15 minutes. Limited awareness of the time-critical nature of this presentation has been reported in multiple triage settings. Studies have shown a role for consumption of honey or sucralfate in delaying tissue injury while awaiting surgical removal.

Evaluating the management timeline of tracheoesophageal fistulas secondary to button batteries: A systematic review.

INTRODUCTION: During the SARS-CoV-2 pandemic, the incidence of pediatric button battery (BB) ingestions has risen. Children have spent more time at home from school, while many parents try to balance working from home and childcare. Additionally, the amount of electronics powered by BB has increased. Tracheoesophageal fistula (TEF) secondary to a retained aerodigestive BB is a devastating development. Management is challenging, and the clinical timeline of watchful waiting versus surgical intervention for TEF is poorly defined in the literature. METHODS: In accordance with PRISMA guidelines, databases searched include PubMed, Scopus, and CINAHL from database date of inception through August 13, 2021. All study designs were included, and no language, publication date, or other restrictions were applied. Case series and reports of TEFs secondary to BBs were included. Clinical risk factors and outcomes were compared between the spontaneous closure and surgical repair groups. RESULTS: A total of 79 studies with 105 total patients were included. Mortality was 11.4%. There were 23 (21.9%) TEFs that spontaneously closed and 71 (67.6%) that underwent surgical repair. Median time to spontaneous closure compared to surgical repair was significantly different (8.0 weeks [IQR 4.0-18.4] vs. 2.0 weeks [IQR 0.1-3.3], p<0.001). Smaller TEFs were more likely to spontaneously close versus being surgically repaired (9.3 mm ± 3.5 vs. 14.9 mm ± 8.3, p=0.022). Duration of symptoms before BB discovery, BB size, time between BB removal and TEF discovery, and location of the TEF were not statistically different between the spontaneous closure and surgical repair groups. CONCLUSION: A TEF secondary to BB ingestion is a potentially deadly complication. Timing of reported TEF spontaneous closure varies significantly. While smaller TEFs may be amenable to healing without surgical repair, no other significant factors were identified that may be associated with spontaneous closure. If clinical status permits, these data suggest a period of observation of at least 8 weeks prior to surgical intervention may be practical for many BB-induced TEFs.

Airway Complications Resulting From Pediatric Esophageal Button Battery Impaction: A Systematic Review.

Importance: Button batteries (BBs) are commonly found in many household items and present a risk of severe injury to children if ingested. The direct apposition of the trachea and recurrent laryngeal nerves with the esophagus puts children at risk of airway injury secondary to the liquefactive necrotic effects of BB impactions. Objective: To review airway injuries, including long-term sequelae, after BB ingestion in children. Evidence Review: For this systematic review, a comprehensive strategy was designed to search MEDLINE, Embase, Cochrane Database of Systematic Reviews, Web of Science, and CINAHL (Cumulative Index of Nursing and Allied Health Literature) from inception to July 31, 2021, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. Additional cases were identified from the National Capital Poison Center BB registry. Individual authors were contacted for additional information. Studies with pediatric patients (<18 years) who developed airway injuries after BB ingestion were included. A total of 195 patients were included in the analysis; 95 were male. The mean (SD) age at BB ingestion was 17.8 (10.2) months. The mean (SD) time from BB ingestion to removal was 5.8 (9.0) days. The 2 most common airway sequelae observed in our series were 155 tracheoesophageal fistulae and 16 unilateral vocal cord paralyses. Twenty-three children had bilateral vocal cord paralysis. The mean (SD) duration of ingestion leading to vocal cord paralysis was shorter than that of the general cohort (17.8 [22.5] hours vs 138.7 [216.7] hours, respectively). Children presenting with airway symptoms were likely to have a subsequent tracheoesophageal fistula or vocal cord paralysis. Conclusions and Relevance: Airway injuries are a severe consequence of BB ingestion, occurring more often in younger children. This systematic review found that tracheoesophageal fistulae and vocal cord paralyses were the 2 most common airway injuries, often requiring tracheostomy. Vocal cord injury occurred after a shorter BB exposure time than other airway injuries. Continued efforts should be directed toward prevention strategies to avoid the devastating sequelae of BB-associated airway injury.

Disc battery ingestion in paediatric age.

AIM: The aim of the present study was to analyse clinical data of children referred for disc battery ingestion in order to assess short- and long-term reported injuries and to identify outcome predictors and trends, define the urgency of intervention and refine treatment guidelines. METHODS: The records of all children admitted to Santobono-Pausilipon Children's Hospital, Naples, Italy for disc battery ingestion from January 2016 to December 2020 were retrospectively reviewed. Odds ratio were computed to assess the association between the different study variables and the rate of complications. RESULTS: We enrolled 118 children. Mild to major complications related to the ingested disc batteries were reported in 12/118 (10.2%) patients. Disc battery oesophageal retention, disc battery diameter >20 mm, together with age below 1 year and symptomatic presentation were the most important factors associated with poor clinical outcome. CONCLUSION: Our data confirm that ingested disc batteries are a serious health hazard and require a timely and qualified medical evaluation. We have identified three predictors of outcome severity: oesophageal retention, large-diameter cells and symptom onset. Disc batteries lodged beyond the oesophagus appear substantially harmless and we may support a more conservative approach.

Magnetic resonance imaging of children following esophageal button battery removal: What are we looking for?

Despite society recommendations that cross-sectional imaging be obtained following removal of ingested button batteries, there is no published consensus on how it effectively guides clinical management. This single institution survey demonstrates a lack of uniformity by clinicians regarding which imaging findings impact management decisions, highlighting the need for further guidelines.

Button battery taping prevents oesophageal injury.

AIM: Most button battery (BB) ingestions in children are unwitnessed leading to prolonged exposures and severe complications. One third of ingestions occur from free BB, that are stored or awaiting disposal. Recommendations have been made to cover the terminals of discarded BB with adhesive tape; however, it is unclear if this practice prevents injury. Our aim was to determine if tape could prevent oesophageal injury in a cadaveric porcine model. METHODS: Electrical, masking, packing and duct tape were compared. One BB was left untaped. Taped BBs were placed in a cadaveric porcine oesophagus controlled for temperature and humidification. Specimens were assessed at 0, 0.5, and hourly for 6 h by visual inspection, temperature and pH. BB voltage was measured before and after testing. All tests were repeated in triplicate. RESULTS: Oesophageal specimens demonstrated burn prevention in the packing and duct tape trials. Burns were seen in 2/3 trials with electrical tape and 3/3 trials with masking tape. pH remained neutral throughout the study for all packing and duct tape specimens. pH remained neutral initially for masking tape but increased rapidly to 12 by 2 h. There was no change in battery voltage for the packing tape and duct tape trials. There was a 16.3% reduction in voltage for masking tape which was similar to controls. CONCLUSIONS: Taping BB with packing tape and duct tape prevented oesophageal burns. This may provide a novel method of burn prevention for loose BB intended for disposal.

[Corrosion damage in oesophagus after digesting a button battery].

Button batteries are present in most households, i.e. in toys, hearing aids and remote controls. Due to technical progression button batteries have become increasingly powerful and have simultaneously increased the risk of severe complications when ingested. In this case report, an X-ray of a ten-month-old baby revealed a button battery trapped in the upper part of oesophagus. The battery was removed within two hours from the time of swallowing, but the battery had inflicted severe damage of the oesophageal mouth. The patient was hospitalized for three days, controlled for three months and showed no signs of swallowing difficulties or other sequelae.

Surgical repair of massive hemorrhage secondary to button battery ingestion causing aortoesophageal fistula.

BACKGROUND: In pediatrics, foreign body ingestion poses unique challenges. Each case is unique given variability in timing, type, and size of object, compounded by underlying comorbidities and age. In the mid-1990s, mortality and morbidity associated with button battery (BB) ingestion (BBI) emerged corresponding to modification in battery fabrication towards higher voltage, large-diameter lithium cells. AIMS: To describe the case and management of a BBI in a pediatric patient necessitating the use of cardiopulmonary bypass and deep hypothermic circulatory arrest (DHCA). MATERIALS AND METHODS: A 17-month-old female presented with the sudden loss of consciousness at home. Chest X-ray revealed an esophageal foreign body suspicious for BBI. A massive upper gastrointestinal bleeding was temporized with packing. The patient was urgently taken to the operating room for sternotomy, establishment of cardiopulmonary bypass (CPB) with deep hypothermic circulatory arrest (DHCA), removal of BB, repair of the left common carotid artery, esophageal, and tracheal injuries. DISCUSSION: Successful management of BBI requires coordinated care and a multidisciplinary approach. A high degree of clinical suspicion for BBI is imperative to facilitate early aggressive interventions. Lateral and anteroposterior chest films should be obtained in any suspected BBI. CONCLUSION: This case demonstrates the utility of CPB and DHCA where control of bleeding secondary to BBI is not otherwise possible.

A novel approach to button battery removal in a two-and-half year-old patient's esophagus after ingestion: a case report.

BACKGROUND: Accidental swallowing of a foreign body occurs more frequently in children than in adults. Among these cases, button battery impaction in the esophagus may cause severe complications. While prevention is always ideal, if button battery impaction is suspected, immediate diagnosis and retrieval are important. CASE PRESENTATION: We introduce a novel method for retrieval of a button battery after ingestion by a 2.5-year-old child. When the patient arrived at our center, the battery was incarcerated in the upper esophagus. The battery could not be removed, despite the use of several methods such as alligator forceps under endoscopy and net retrieval. We decided to use a novel method that combined endoscopic balloon extraction and forceps retrieval. This resulted in a push-and-pull effect, creating synergy and easy removal of the battery. There were no long term complications based on the follow-up endoscopy examination. CONCLUSIONS: This new procedure was very effective for removing the esophageal foreign body. When button battery in esophagus was too tight to be removed by the traditional retrieval methods, this procedure was suggested to use. It could be performed at medical institutions. If it fails or esophageal perforation (iatrogenic or spontaneous) occurs, pediatric surgeons could take over immediately.

[Case Series Report: Management of Anesthesia in Children Undergoing Complex Surgery of Tracheoesophageal Fistula after Ingestion of Button Batteries]. / Fallberichte: Kinder mit tracheoösophagealer Fistel nach Knopfbatterieningestion.

Button battery ingestions in children increased in recent years and may lead to life-threatening complications, especially if the battery is impacted in the esophagus. The pH close to the negative pole of the battery can rise in a very alkalotic range (pH > 10) leading to severe tissue damage. Therefore, in this case series report, the clinical courses of four children with button battery ingestion leading to tracheoesophageal fistulas are presented. The diagnosis and removal of the button battery was delayed in all cases. The surgical reconstruction of the trachea was performed in intravenous anesthesia and with extended monitoring. The intraoperative oxygenation was maintained using a combination of extracorporeal membrane oxygenation (ECMO) and mechanical ventilation via an endobronchial tube. To prevent these life-threatening complications, the awareness of the parents and child care providers should be raised, and the manufacturers should redesign their products to secure the battery compartment. In children with suspected battery ingestions, the immediate localization and removal of the battery (< 2 h) is of highest importance. Local administration of honey or sucralfate can be considered in ingestions < 12 h but should not delay an endoscopic removal.

Association between the corrosion of ingested lithium button battery in the esophagus and its complications in pediatric patients.

PURPOSE: The incidence of lithium button battery ingestion has been increasing recently, which results in severe complications. We aimed to demonstrate the association between the corrosion of lithium button batteries in the esophagus on radiographs and their complications. METHODS: The nine pediatric patients included in this study were classified into two groups based on the presence of severe complications. The presence and degree of corrosion on plain radiographs were evaluated. The degree of corrosion was classified into the following three grades; none: 0%; moderate: 1-50%; severe: 51-100%. Fisher's exact test was used for statistical analyses. RESULTS: Of the nine patients, five showed complications. The number of patients who had grade none, moderate, and severe degrees of corrosion was three, four, and two, respectively. The incidence of severe complications differed significantly between the incidence of lithium button batteries' contour (without vs. with severe complications [presence/absence of corrosion] = 1/3 vs. 5/0, respectively; P = 0.0476). In cases with "none" degree of corrosion, all three cases had no complication, and in cases with a "severe" degree of corrosion, all two cases had complications. CONCLUSION: The cases with the presence of corrosion of lithium button batteries had a higher tendency to have severe complications. Therefore, physicians should anticipate the presence of severe complications in pediatric patients with corrosion more than those without corrosion.

The Hidden Danger of Lithium Battery-Powered Electric Bicycles and Scooters: A Case Series of the Israeli National Burn Center Experience.

Electric-powered bicycles and scooters that use rechargeable lithium batteries are an urban transportation alternative and have become increasingly popular. However, in recent years, there has been an increase in patient admissions to the Israeli National Burn Center with burns associated with their use. In this case series of all patients (n = 9) referred to the Emergency Department (February 2016-October 2020) with lithium-related battery burns from electric-powered bicycles and scooters, we present burn depth, size, treatment, inhalation injuries, and hospitalization. All patients were admitted to the Israeli National Burn Center for treatment. The average TBSA was 27.5% (range 3%-57%). All but one patient had a combination of partial to full-thickness burns affecting the upper and lower limbs. Three patients sustained inhalation injuries and a total of four patients required intubation. Seven patients required surgery that included debridement and, in most cases, skin grafting. The availability and increase in the use of battery-powered bicycles and scooters may lead to an increase in injuries and death if consumers are not aware of the potential dangers related to the safe use of lithium batteries.

Retained metal fragments following esophageal button battery impaction.

Button battery (BB) impaction in the esophagus requires immediate endoscopic removal and meticulous follow-up, including serial cross-sectional imaging, preferably with magnetic resonance imaging (MRI). However, BBs quickly degrade in the esophagus, and metallic fragments may remain in the injured mucosa following removal. This metallic debris can cause thermal injury during MRI, potentially aggravating local injury. We aimed to explore whether such metallic fragments could be identified on imaging following BB removal. In this study, we conducted a retrospective review of children (0-18 years) presenting with BB impaction in the esophagus between 2014 and 2020. Endoscopy reports and imaging studies were blindly reviewed by a pediatric gastroenterologist and a pediatric radiologist. Of 161 cases of battery ingestion, 14 (8%) underwent endoscopy, and in 9 (5%) a BB was impacted in the esophagus. The median time from ingestion to BB removal was 8 h (range 2-48 h). The median time from removal to CT was 44 h (range 0.5-104 h). BB appearance ranged from mild corrosion to visible debris. Pre-removal plain films showed irregular battery contour suggesting corrosion (5/7 plain films). In 7/9 CT scans (78%), high-attenuation esophageal content (median 266HU (range 140-1151)), which may represent metallic debris, was identified. Five patients had a follow-up CT which still showed gradual resolution of the high-attenuation content.Conclusions: we describe a new finding on CT following BB removal which might represent metallic debris. Clinicians should be aware of these findings which potentially may be harmful during MRI used in the ongoing assessment of esophageal injury. What is Known: • Button batteries are a dangerous pediatric foreign body with potentially fatal vascular complications. What is New: • Metallic debris was identified on computerized tomography following button battery removal in most children. • We bring to attention this new finding which may affect clinical management, as minimal metallic content can cause burns during MRI.
