Surgical management and morbidity of pediatric magnet ingestions

Development and Validation of a Clinical Nomogram for Predicting Complications From Pediatric Multiple Magnet Ingestion: A Large Retrospective Study

INTRODUCTION

This study aimed to develop and validate a reliable nomogram based on clinical factors to predict complications associated with pediatric multiple magnet ingestion, addressing the urgency and controversy surrounding its management.

METHODS

Patients aged 0-18 years with multiple magnet ingestion diagnosed at the Shenzhen Children's Hospital between January 2017 and December 2023 were enrolled. Clinical data were analyzed using least absolute shrinkage and selection operator regression and multifactor logistic regression analyses to screen for risk factors. A model was constructed, and a nomogram was plotted. Model performance was evaluated and internally validated using the area under the curve (AUC), Hosmer-Lemeshow test, calibration curve, decision curve analysis, and 1,000 bootstraps. We calculated the optimal cutoff value, sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the prediction model.

RESULTS

Of the 146 patients, 57 (39.0%) experienced complications. The nomogram included age, multiple ingestions, vomiting, abdominal pain, and abdominal tenderness. The AUC was 0.941, and the internally validated AUC was 0.930. The optimal cutoff value selected as a predictive value was 0.534, with a sensitivity of 82.5%, specificity of 93.3%, positive predictive value of 88.7%, negative predictive value of 89.3%, and accuracy of 89.0%. The Hosmer-Lemeshow test yielded a P value of 0.750. The calibration plot exhibited high consistency in prediction, and decision curve analysis showed excellent net benefits.

DISCUSSION

Our nomogram demonstrates excellent discrimination, calibration, and clinical utility and may thus help clinicians accurately assess the risk of complications from pediatric multiple magnet ingestion.

Early colonic-preparation and salvage laparoscopic appendectomy (ECSLA)- innovative protocol for the management of magnets ingestion

BACKGROUND

Ingestion of magnets carries risks for significant morbidity. We propose a new protocol designed to reduce the need for surgery, shorten length of stay, and decrease morbidity.

METHODS

The Early Colonic-preparation and Salvage Laparoscopic Appendectomy (ECSLA) protocol includes initiating colonoscopy preparation upon admission in asymptomatic patients if magnets are not amenable to removal by gastroscopy, and laparoscopic magnets retrieval via appendectomy if surgery is eventually needed. The protocol was initiated in May 2023. A retrospective study of all cases of ingested magnets in children in our institution during July 2020 - January 2024 was conducted to retrieve and analyze demographic, clinical, imaging, management, and outcome data.

RESULTS

During the 3.5-year study period, 13 cases of ingested multiple magnets were treated, including 7 cases since initiation of ECLSA protocol, with no complications. Since initiation of ECSLA protocol, Early colonic preparation resulted in spontaneous passage of magnets (two cases) and successful colonocsopic removal (three cases), with two cases in which magnets were retrieved via gastroscopy upon admission, and no patients needing surgical intervention. Length of stay (LOS) was short (1-3 days).

CONCLUSIONS

The ECSLA protocol is a promising tool for preventing surgical intervention and complications and for possibly shortening LOS in children who have ingested multiple magnets.

Utilization of Single-Incision Laparoscopy in the Management of Ingested Magnets

Background: A ban on neodymium magnets was lifted by the U.S. Consumer Product Safety Commission in 2016. Pediatric gastroenterologists and surgeons were increasingly tasked with removing these problematic objects. The purpose of this study was to assess the utility of single-incision laparoscopic surgery (SILS) in the management of ingested magnets. Patients and Methods: This is a single-center, retrospective assessment of surgical interventions for ingested magnets. International Classification of Disease, 10th revision codes were used to identify 349 patients ≤21 years of age evaluated for foreign body ingestion over a 4.5-year period. A medical record review helped isolate 29 (8.3%) magnet ingestions, 9 requiring surgical intervention. RedCap was used for analysis. Results: Of 9 surgical patients, 7 underwent SILS intervention by 1 surgeon. Another surgeon performed an open operation, whereas a third performed a multiport operation. Of the 7 SILS cases, 3 were completed without conversion to open. In one of these cases, bowel resection with primary anastomosis was performed. For SILS cases, average operating room time was 109 minutes (38-170 minutes), time to enteral feeds was 23 hours (0.28-79.2 hours), and hospital length of stay (LOS) was 3.8 days (1.96-6.68 days). Thirty-day readmission for SILS was 14.3%. No other complications were observed. Conclusions: SILS has been safely utilized for magnet retrieval. It offers an ability to identify the affected intestinal segment and an opportunity to intervene extracorporeally through an uncapped port. In addition, knowing where matted bowel is located can direct a limited incision during conversion to laparotomy. This may confer benefits of decreased pain, shortened time to enteral feeds, and decreased hospital LOS.

Successful endoscopic removal of high-power magnetic balls embedded in the duodenal wall

The dangers of magnet ingestion are well known. When multiple magnets are ingested, interventional removal is often necessary to prevent and/or treat complications. Despite reports of both endoscopic and surgical techniques in the literature, there is a lack of clear guidance on the best method for removal of high-power magnets when they are embedded within the intestinal wall (increasing concern for fistulation, perforation, and bowel wall necrosis). This case demonstrates the successful endoscopic removal of magnetic balls incidentally identified on X-ray and found to be embedded in the duodenal wall in a critically ill 2-year-old patient. Endoscopic removal can be considered in similar situations, if all resources (interventional endoscopy and pediatric surgery) are available to proceed safely.

Accidental ingestion of multiple magnetic beads by children and their impact on the gastrointestinal tract: a single-center study

OBJECTIVE

In this study, we aimed to enhance the treatment protocols and help understand the harm caused by the accidental ingestion of magnetic beads by children.

METHODS

Data were collected from 72 children with multiple gastrointestinal perforations or gastrointestinal obstructions. The 72 pediatric patients were divided into a perforation and a non-perforation group. The data collected for the analysis included the gender, age, medical history, place of residence (rural or urban), and symptoms along with the educational background of the caregiver, the location and quantity of any foreign bodies discovered during the procedure, whether perforation was confirmed during the procedure, and the number of times magnetic beads had been accidentally ingested.

RESULTS

The accuracy rate of preoperative gastrointestinal perforation diagnosis via ultrasound was 71%, while that of the upright abdominal X-ray method was only 46%. In terms of symptoms, the risk of perforation was 13.844 and 12.703 times greater in pediatric patients who experienced vomiting and abdominal pain with vomiting and abdominal distension, respectively, compared to patients in an asymptomatic state. There were no statistical differences between the perforation and the non-perforation groups in terms of age, gender, medical history, and the number of magnetic beads ingested (P > 0.05); however, there were statistical differences in terms of white blood cell count (P = 0.048) and c-reactive protein levels (P = 0.033). A total of 56% of cases underwent a laparotomy along with perforation repair and 19% underwent gastroscopy along with laparotomy. All pediatric patients recovered without complications following surgery.

CONCLUSION

Abdominal ultrasonography and/or upright abdominal X-ray analyses should be carried out as soon as possible in case of suspicion of accidental ingestion of magnetic beads by children. In most cases, immediate surgical intervention is required. Given the serious consequences of ingesting this type of foreign body, it is essential to inform parents and/or caregivers about the importance of preventing young children from using such products.

Endoscopic retrieval of 195 incidentally found ingested magnets in a pediatric patient: The limitations of radiography

Ingestion of magnetic foreign bodies in children can present elusively on radiographs, requiring detailed history for accurate intervention guidance. Clustering and the weight of multiple magnets may indicate falsely distal positions in the GI tract.

A case report of multiple foreign body ingestion with a ring-like configuration: The magnetic effect

INTRODUCTION

Magnetic foreign body (FB) ingestion represents a significant health hazard among children. The increasing use of small attractive magnets as toys or parts of various household accessories makes it easily accessible to children. The aim of this report is to raise awareness of public authorities and parents around exposing children to magnetic toys.

CASE PRESENTATION

We report a case of multiple FB ingestion in a 3-year-old child. Radiological imaging revealed multiple round objects arranged in a circular shape resembling a ring. Surgical exploration showed multiple intestinal perforations attributed to the magnetic attraction between the objects.

CLINICAL DISCUSSION

Although more than 99 % of ingested FB pass without surgical intervention, ingestion of multiple magnetic FB provides a substantially higher risk of injury due to self-association and therefore requires a more aggressive clinical approach. A stable or clinically benign condition, though common, does not necessarily mean a safe situation in the abdomen. Literature review suggests that emergency surgical intervention should be pursued to avoid potentially life-threatening complications; perforation and peritonitis.

CONCLUSION

Multiple magnet ingestion is rare, but can result in serious complications. We recommend early surgical intervention before gastrointestinal complications develop.

Pediatric Magnet Ingestion, Diagnosis, Management, and Prevention: A European Society for Paediatric Gastroenterology Hepatology and Nutrition (ESPGHAN) Position Paper

Magnet ingestion is a special category of foreign body ingestion associated with high levels of morbidity and mortality worldwide, particularly if it is associated with staggered ingestion of multiple magnets or with simultaneous ingestion of other metallic foreign bodies, especially button batteries. A special category of magnet ingestion is the ingestion of earth magnets, which have higher levels of magnetism and therefore, potentially, carries a worse outcome. Legislative bodies, scientific Societies and community-led initiatives have been implemented worldwide with the aim of mitigating the effects of this growing, yet avoidable potential medical emergency. A scoping literature review summarized epidemiology, diagnosis, management, and prevention, including an algorithm for the diagnosis and management of magnet ingestion is presented and compared to previously published reviews and position papers (North American Society of Pediatric Gastroenterology, Hepatology and Nutrition, National Poison Center, Royal College of Emergency Medicine). The main emphasis of the algorithm is on identification of staggered/multiple magnet ingestion, and early joint gastroenterology and surgical consultation and management.

Multiple magnet ingestion in children: A problem on the rise

AIM

Ingestion of multiple magnets is increasing these last 15 years in children. They have resulted in numerous reports of serious gastrointestinal complications such as bowel obstruction, ischaemia, necrosis, perforation and fistula formation and even led to death. The increasing number of world-wide reports of complications secondary to magnet ingestion and a frequently delayed diagnosis point to a lack of awareness about these risks among medical care-givers in our country and parents in general.

METHODS

We reviewed retrospectively all cases of multiple magnet ingestion that required a gastro-intestinal or surgical procedure for removal from 2009 to 2020.

RESULTS

Five children underwent gastroscopy removal and three colonoscopy removal of the magnets. Five patients required surgical (laparotomy or laparoscopy) removal of multiple magnets with intestinal perforations.

CONCLUSIONS

We propose an updated management algorithm for multiple magnet ingestion to highlight awareness among primary physicians and parents of the presenting circumstances and symptoms as well as the potential complications associated with multiple magnet ingestion.

Contained Jejunal Perforation Secondary to Ingestion of Magnet Balls in a Nonfatal Drowning Child

Most ingested foreign bodies often pass through the gastrointestinal tract uneventfully; however, complications such as perforation do occur. Jejunal perforation is a known complication of abdominal trauma. While gastrointestinal tract injury due to the ingested foreign body such as a toothpick, fishbone, and battery among others are common, jejunal perforation is not very common in pediatrics.

We report an unusual case of jejunal perforation that was diagnosed after a child was admitted to the pediatric intensive care unit for nonfatal drowning. A 15-month-old girl presented to our emergency room after she was found submerged in a swimming pool. She was unwitnessed for about ten minutes. At the scene, she was apneic, and cyanotic but had a pulse. Cardiopulmonary resuscitation was started and she was brought to our emergency room. She was managed for her drowning injuries and was accidentally found to have a foreign body on her abdomen by x-ray. She had no signs or symptoms of perforation, however, after questioning the parents they told us that they brought her a toy containing magnet balls about one month ago. After stabilizing her respiratory status and correcting her acidosis, an upper gastrointestinal (GI) endoscopy was done that showed jejunal perforation and multiple magnets. A consultation was done immediately for the pediatric surgery team then the perforation was repaired. High-powered magnets represent a serious health hazard if ingested due to risks of gastrointestinal perforation. It is important to have a high index of suspicion for potential injuries, especially silent ones. One of the rare complications is contained jejunal perforation.

Multicentre study of magnet ingestion in Spanish paediatric emergency departments

INTRODUCTION

The ingestion of magnetic objects can cause complications in children, and there are no epidemiological or clinical data on the subject in Spain.

OBJECTIVES

To determine the incidence, epidemiological characteristics and management of magnet ingestion in paediatric emergency departments in Spain.

MATERIAL AND METHODS

Prospective observational multicentre study conducted over a 3-year period. The study universe consisted of patients aged less than 14 years.

RESULTS

The incidence was 4.8 cases per 100 000 emergency care episodes. Of the 72 patients included (mean age, 7.2 years), 54% were male. Seven percent had neuropsychiatric disorders. Sixty-one percent of the magnets were spherical and 69% came from toys. The size was variable, most frequently between 5 and 10 mm (50%), and ranging from 3 to 30 mm. Eighty-six percent of patients were asymptomatic. The most frequent symptom was abdominal pain. Eighty-three percent of the patients sought medical care within 6 h of ingestion and 92% within 24 h. Thirty-one percent of the cases were of multiple ingestion. Endoscopy was required for extraction in 15% of cases, a proportion that rose to 36% in the group of cases of multiple ingestion. None of the patients required surgery. We did not observe any gastrointestinal complications of magnet ingestion.

CONCLUSIONS

The ingestion of multiple magnets is less frequent than single magnet ingestion, and we did not observe any complications despite the lower frequency of procedures compared to other studies.

Ingested Foreign Bodies Can Cause Appendicitis and Perforation: A Multi-Institutional Case Series

INTRODUCTION

Appendicular foreign bodies are a rare, under-described cause of appendicitis. We performed this study to determine the varied causes and consequences of foreign-body appendicitis.

METHODS

On retrospective review of the pathology archives of seven institutions, we identified 56 appendix specimens containing a foreign body (defined as ingested, non-digestible material). We recorded the type of foreign body, patient age and sex, and other findings, as available.

RESULTS

Mean patient age was 7.7 years (range: 1 day-18 years). The foreign bodies included hair, plant material, magnets, other metallic material, BB pellets, foreign material not otherwise specified, and other miscellaneous objects. Of 48 cases with available clinical information, 31 patients presented with abdominal pain, and 22 were preoperatively diagnosed as having appendicitis/appendicular inflammation. Seven patients had appendiceal perforation (13%). The foreign body was grossly identified in 34/47 cases with available gross descriptions. Twenty-seven cases had an identifiable foreign body microscopically; 10 were associated with giant cell reaction.

DISCUSSION

Hair and plant materials were the most common foreign objects found in the appendix; they often cause mucosal damage and giant cell reaction. Metallic objects were less common. Although appendicular foreign bodies in children are rare and sometimes asymptomatic, they may lead to perforation.

Magnet and button battery ingestion in children: multicentre observational study of management and outcomes

BACKGROUND

Magnets and button batteries (BBs) are dangerous ingested foreign bodies in children. The scale and consequences of this public health issue in the UK are unknown. This study aims to report the current management strategies and outcomes associated with paediatric magnet and BB ingestion in the UK.

METHODS

This multicentre, retrospective observational study involved 13 UK tertiary paediatric surgery centres. Children aged under 17 years, admitted between 1 October 2019 and 30 September 2020, following magnet, or BB ingestion were included. Demographics, investigations, management, and complications were recorded.

RESULTS

In total, 263 patients were identified, comprising 146 (55.5 per cent) magnet, 112 (42.6 per cent) BB, and 5 (1.9 per cent) mixed magnet BB ingestions. Median (interquartile range) age was 4.8 (2.0-9.1) years and 47.5 per cent were female. In the magnet group, 38 (26.0 per cent) children swallowed single magnets, 3 of whom underwent endoscopic retrieval for oesophageal or gastric impaction. Of the 108 (74.0 per cent) children who swallowed multiple magnets, 51 (47.2 per cent) required endoscopic or surgical intervention, predominantly for failure of magnets to progress on serial imaging. Bowel perforations occurred in 10 children (9.3 per cent). Younger age and ingestion of greater numbers of multiple magnets were independently associated with surgery. BB ingestion caused morbidity in 14 children (12.5 per cent) and life-threatening injuries in two (1.8 per cent); the majority were caused by oesophageal BBs (64.3 per cent).

CONCLUSION

Multiple magnet and BB ingestions are associated with significant morbidity. Action must be taken at an international level to regulate the sale of magnets and BBs, and to raise awareness of the risks that these objects pose to children.

Decade of the dangers of multiple magnet ingestion in children: A retrospective review

AIM

Magnet ingestion has become more frequent in children as magnetic toys and jewellery have been popularised, with the potential to cause significant morbidity. Our aim was to describe our experience at a tertiary paediatric surgical centre.

METHODS

Retrospective review of patients admitted with multiple magnet ingestion (January 2011-December 2020). Division into an intervention group and conservative group. Comparisons included demographics, number of magnets and clinical outcomes. Data analysis with a Student's t-test and ROC Curve, P value of <0.05 was significant.

RESULTS

A total of 23 patients were identified with a total of 150 magnets ingested. The majority required an intervention for magnets retrieval (15/23, 65.2%), 11/15 (73.3%) surgical and 4/15 (26.7%) endoscopic. In the surgery group, 6/11 (54%) presented with an initial perforation and 1/11 (9.1%) an entero-enteric fistula. One patient (9.1%) had a multi-site anastomotic leak post-operatively. The conservative group had a significantly lower median number of ingested magnets (2 (2-6) vs. 7 (2-40), P = 0.03) and median length of stay (1 (1-4) vs. 7 (1-24), P = 0.03). ROC curve analysis revealed ingestion of >3 magnets had a sensitivity of 86.7% (95% CI: 62.1-97.6%) and specificity of 87.5% (95% CI: 53.0-99.4%) for requiring an intervention.

CONCLUSION

This series highlights a significant morbidity in children with a higher incidence of intervention following ingestion of more than three magnets. There is a strong requirement for the creation and adherence to new legislature involving industry standards.

High-Powered Magnet Exposures in Children: A Multi-Center Cohort Study

BACKGROUND AND OBJECTIVES

High-powered magnets were effectively removed from the US market by the Consumer Product Safety Commission (CPSC) in 2012 but returned in 2016 after federal court decisions. The United States Court of Appeals for the 10th Circuit cited imprecise data among other reasons as justification for overturning CPSC protections. Since then, incidence of high-powered magnet exposure has increased markedly, but outcome data are limited. In this study, we aim to describe the epidemiology and outcomes in children seeking medical care for high-powered magnets after reintroduction to market.

METHODS

This is a multicenter, retrospective cohort study of patients aged 0 to 21 years with a confirmed high-powered magnet exposure (ie, ingestion or insertion) at 25 children's hospitals in the United States between 2017 and 2019.

RESULTS

Of 596 patients with high-powered magnet exposures identified, 362 (60.7%) were male and 566 (95%) were <14 years of age. Nearly all sought care for magnet ingestion (n = 574, 96.3%), whereas 17 patients (2.9%) presented for management of nasal or aural magnet foreign bodies, 4 (0.7%) for magnets in their genitourinary tract, and 1 patient (0.2%) had magnets in their respiratory tract. A total of 57 children (9.6%) had a life-threatening morbidity; 276 (46.3%) required an endoscopy, surgery, or both; and 332 (55.7%) required hospitalization. There was no reported mortality.

CONCLUSIONS

Despite being intended for use by those >14 years of age, high-powered magnets frequently cause morbidity and lead to high need for invasive intervention and hospitalization in children of all ages.

An Unfortunate Union: A Case of Multiple Magnet Ingestion in a Pediatric Patient

Magnets are among the most dangerous foreign objects that a child can ingest. If more than one magnet is ingested, the attraction between loops of the bowel can bring adjacent loops closer together, leading to perforation, obstruction, or fistulization. Pediatric magnet ingestion patients often require endoscopic or surgical intervention to retrieve the objects and repair the damage created by the magnets. Due to the risks of surgical intervention, management is done with strict adherence to the rare earth magnet ingestion algorithm. We highlighted a pediatric case of multiple magnet ingestion, and the steps that were taken to manage the patient. Our case highlights the potential for complications and the importance of adherence to the management algorithm in these patients. Epidemiology, mechanisms, algorithms, and outcomes for pediatric magnet ingestion patients were discussed.

Application of high-frequency ultrasound in the diagnosis of gastrointestinal magnet ingestion in children

BACKGROUND

The incidence of magnet ingestion by children has recently increased in China. Magnet ingestion is associated with an extremely high risk of gastrointestinal damage because loops of bowel can become trapped and squeezed between multiple magnets in different locations. However, the lack of imaging sensitivity makes clinical decision-making difficult.

OBJECTIVE

This study was conducted to investigate the performance of ultrasound in diagnosing gastrointestinal magnet ingestion in children.

METHODS

From April 2017 to February 2021, all children with a history of magnet ingestion or a diagnosis of gastrointestinal magnet as shown by x-ray or ultrasound in our hospital were included as study candidates. Patients who were lost to follow-up or had known malformations of the gastrointestinal tract were excluded. Eligible patients were those with surgical or endoscopic confirmation of gastrointestinal magnet, those who passed the magnet out of the alimentary tract without assistance, and those with confirmed absence of the magnet on abdominal x-ray examination after 1 month of conservative treatment. All eligible patients' ultrasound and x-ray examination data were evaluated. The sensitivity, specificity, and area under the curve (AUC) of ultrasound was calculated for diagnosing magnet ingestion, locating the magnet (stomach, small intestine, or colon), and confirming the phenomenon of wall entrapment.

RESULTS

Of 112 patients, 107 had a magnetic foreign body and 5 did not. Magnets were correctly detected by ultrasound in 97 patients, with an observed sensitivity of 90.65% and specificity of 100%. Satisfactory sensitivity was obtained for ultrasound localization of gastric magnets (96.30%) and small intestinal magnets (100.00%), but sensitivity for ultrasound localization of colonic magnets was relatively poor (73.33%). The discrimination of wall entrapment by ultrasound was good (AUC = 0.93), with an observed sensitivity and specificity of 92.00% and 93.62%, respectively.

CONCLUSIONS

Ultrasound can be used to locate gastrointestinal magnets (in the stomach, small intestine, or colon) with good clinical efficacy in identifying wall entrapment.

Endoscopic retrieval of ingested magnets in children and role of magnetic retrievers

Background

Various high-powered magnetic toy sets constitute a major hazard as the small magnets can be easily swallowed or aspirated by young children. Multiple ingested magnets or the ingestion of a magnet with another metallic object can pose a serious threat as this may lead to bowel perforation, fistulation, intestinal volvulus, bowel obstruction and death.

Main body

Retrieval of ingested magnets from the stomach is routinely performed endoscopically but can become a painstaking quest involving many tedious attempts to secure the magnet(s). Historically, pre-routine endoscopy, magnetic retrievers were used under fluoroscopic control for the removal of metallic objects in the stomach. With the advent of endoscopic retrieval instruments, they fell out of favour and are no longer readily available on the market. Despite this, conventional endoscopic instruments are likely to be less effective than endoscopic-assisted magnetic retrievers due to confounding weak bonds which form between the metal retrieval device and the magnet.

Preoperative testing, and selection of the retrieval instrument with the strongest coupling effect with a magnet, might be beneficial. A simple, endoscopic-assisted magnetic retriever created in theatre can allow for more effective, time-efficient and safe removal of ingested magnets under direct vision.

Conclusion

Urgent removal of multiple ingested magnets or a single ingested magnet coupled with another ingested metallic object should be highlighted. Stricter implementation of a widespread ban over loose magnetic toys is needed. Standardised protocols for the surgical management of ingested magnets should be available in every hospital.

Successful removal of two magnets in the small intestine by laparoscopy and colonoscopy: A case report

BACKGROUND

Ingestion of multiple magnets can cause serious gastrointestinal complications, such as obstruction, fistulae, and perforation. When multiple magnets traverse the stomach, coordination between pediatric gastroenterologists and pediatric surgeons is recommended, and ultimate management is required dependent on clinical concerns.

CASE SUMMARY

A 5-year-old girl swallowed 2 small magnets that then remained in the right lower quadrant (RLQ) of the abdomen for 3 d; this required endoscopic and laparoscopic intervention. Abdominal X-ray and computed tomography revealed high-density objects in the RLQ area. Colonoscopy after proper bowel preparations on the third day of ingestion revealed no foreign body in the colonic area or the end of the ileum. The two magnets were removed via colonoscopy with laparoscopic intervention.

CONCLUSION

It is important to establish effective coordination between pediatric gastroenterologists and pediatric surgeons when using a non-invasive procedure to remove magnets.

Ball magnet ingestion in children: a stronger and more dangerous attraction?

INTRODUCTION

The ingestion of small, strong, rare-earth magnets, also termed 'ball magnets', can rapidly result in life-threatening bowel injuries. The objective of this study was to report the incidence and management of 'ball magnet' ingestion in children across the UK and to discuss the potential implications for policy-makers and public awareness campaigns.

METHODS

In this multi-centre survey of UK major trauma centres (MTCs), paediatric patients admitted to hospital following 'ball magnet' ingestion from 1 January 2020 to 31 December 2020 were included.

RESULTS

Responses were received from 11 MTCs (52%) reporting a total of 53 children admitted with 'ball magnet' ingestion over the 1-year study period. Most patients (n=51) presented following unintentional ingestion. 36 (68%) patients presented asymptomatically following witnessed or reported ingestion. In symptomatic patients, abdominal pain and vomiting were the the most common symptoms. The median number of 'ball magnets' ingested was 5.0 (IQR 3.0-7.8), range 1 to 63. 27 (51%) patients underwent operative intervention; laparotomy being the the most common (n=24, 89%). There were no deaths reported during the study period.

CONCLUSION

This multi-centre survey from the UK demonstrates the serious impact of 'ball magnet' ingestion in children. Clinicians, regulators and caregivers must work symbiotically in order to prevent, recognise and reduce life-threatening bowel injuries.

Multiple magnetic foreign body ingestion in pediatric patients: a single-center retrospective review

OBJECTIVE

Foreign body (FB) ingestion is increasingly common in children, and ingestion of multiple magnetic FBs can cause serious injuries. This study aimed to identify the clinical features and management options of such cases.

METHODS

A retrospective review was conducted of 35 pediatric patients diagnosed as having ingested multiple magnetic FBs.

RESULTS

The main clinical manifestations were abdominal pain, vomiting, and fever. Of the 35 patients, 6 (17.1%) were conservatively treated and the remaining 29 (82.9%) were surgically treated. Of those who were surgically treated, 26 underwent exploratory laparotomy and 3 underwent laparoscopic surgery that was switched to open surgery. Intestinal structure and function were restored without complications in patients who underwent successful perforation repair following removal of multiple magnetic FBs.

CONCLUSIONS

Ingestion of multiple magnetic FBs can lead to intestinal perforations, bowel strangulation, and necrosis. Accordingly, timely diagnosis and effective management of multiple magnetic FB ingestions in pediatric patients are of paramount importance to reduce further complications.

Management of magnetic foreign body ingestion in children

Magnetic foreign bodies ingestion is a special cause for attending emergency department. Here, we aim to analyze the characteristics and treatments of children who ingested magnetic foreign bodies (Buckyballs). Data were collected from children who ingested Buckyballs between February 2017 and October 2019. A retrospective analysis was performed to summarize the experiences of conservative treatment, gastroscopy and surgery when dealing with Buckyballs ingestion.A total of 49 patients with buckyballs ingestion were identified, of whom 11 underwent conservative treatments, 6 underwent gastroscopy, and 32 underwent surgery. Among such individuals, eight patients (72.7%) had a successful conservative treatment (number of Buckyballs [NB]: 3.5[IQR: 2.0-4.0]); four patients (66.7%) had Buckyballs successfully removed by gastroscopy (NB: 3.5[IQR: 3.0-5.5]); 16 asymptomatic (50%) patients (NB: 4.0[IQR: 3.0-8.0]) and 16 symptomatic (50%) patients (NB: 8.5 [IQR: 6.25-11.75]) received emergency surgery. Compared to patients who received conservative treatment, the number of ingested Buckyballs was significantly higher in patients who received surgery or gastroscopy (7.0 [IQR: 3.0-10.75] vs 3.5 [IQR: 2.0-4.0], P < .05). The risk of intestinal perforation was significantly higher in symptomatic patients (P < .05) compared to asymptomatic patients.Gastroscopy is recommended when Buckyballs are in the stomach or esophagus. In asymptomatic patients, conservative treatment can be considered for 4 to 6 days. Patients failing conservative treatment, or those who are symptomatic should undergo emergency surgery.

Clinical report and analysis of 24 cases of multiple magnetic beads foreign body in gastrointestinal tract of children

BACKGROUND/AIMS

This study aimed to analyze the data of 24 cases of multiple perforation or obstruction of the digestive tract caused by accidental ingestion of magnetic beads, to improve the understanding of its harmfulness to children and explore the best treatment.

MATERIALS AND METHODS

In total, 24 cases were collected and retrospectively analyzed. These patients were divided into two groups: perforation group and non-perforation group. The medical history, number of magnetic beads, white blood cell (WBC) count, and C-reactive protein (CRP) were analyzed.

RESULTS

There was no significant difference in age, gender, medical history, number of magnetic beads, and WBC count between the perforation group and non-perforation group, but there was a significant difference in CRP. After the diagnosis, 70% of the cases underwent laparotomy and perforation repair. All cases recovered smoothly after the operation, and no complications occurred during the follow-up.

CONCLUSION

This study offers diagnosis and treatment methods for the perforation or obstruction of the digestive tract caused by accidental ingestion of magnetic beads and raises the awareness regarding the harmfulness of the presence of foreign bodies in the digestive tract.

Magnetic compression anastomosis for rectal atresia following necrotizing enterocolitis: A case report

RATIONALE

Rectal atresia caused by necrotizing enterocolitis (NEC) is a serious and rare complication in children. Magnetic compression anastomosis (MCA) has been effectively applied in children with congenital oesophageal atresia and biliary atresia. Herein, we reported a case of successfully application of MCA in an infant with rectal atresia following NEC.

PATIENT CONCERNS

A 30 weeks premature birth female fetal infant was transferred to our neonatal intensive care unit due to premature delivery, low birth weight, and neonatal respiratory distress. On postpartum day 11, the infant developed abdominal distension and mucosanguineous feces. This infant was then clinically diagnosed as NEC. She underwent anesthesia and intestinal fistula operation on postpartum day 11 because of NEC.

DIAGNOSIS

After 3 months, radiographic examination revealed rectal atresia and stricture.

INTERVENTIONS

This infant was successfully treated with MCA following a cecum-rectal anastomosis and ileocecal valve was reserved.

OUTCOMES

On postoperative day 9, she passed the 2 magnets per rectum. In addition, there were no difficult defecation or fecal incontinence or other short-term complications. After the 7-month follow-up, the patient had an excellent clinical outcome.

LESSONS

MCA is a feasible and effective method for treating rectal atresia in infants.

Magnet ingestion by children: A retrospective study in a medical center in Taiwan

BACKGROUND

The ingestion of multiple magnets may lead to severe complications including bowel obstruction, perforation, fistula, peritonitis, short bowel syndrome, life-threatening injuries, and even death. The annual case number of high-powered neodymium magnets ingestion has been increasing in the western world and the dearth of available data demonstrates that this issue has been neglected in Taiwan.

METHODS

We searched the electronic medical records of our institution for patients younger than 18 years old who were diagnosed with, who had ever visited our emergency department, or been hospitalized for magnetic foreign body ingestion between January 2009 and March 2018. Demographic data including the number, shape, and size of magnets ingested, the clinical presentation, type of intervention, and complications were reviewed.

RESULTS

Thirteen patients who met the enrollment criteria were analyzed. One patient was documented between 2009 and 2013, and twelve were documented between January 2014 and March 2018. Five of the cases documented between 2014 and 2018 had ingested Buckyballs. The median age of the patients was 5 years. All of the patients with clinical symptoms had ingested more than one magnet and required endoscopic or surgical intervention. Bowel perforation or deep ulcer with impending perforation was found in three patients during surgery.

CONCLUSION

The number of children who visited our emergency department or were hospitalized due to the ingestion of magnets has increased recently. The presence of high power of neodymium magnets in many products increases the risk of ingesting multiple magnets resulting in serious complications. Therefore, stricter policies are needed to prevent children from obtaining products that contain magnets.

A Child With a Gastrocolic Fistula After Ingesting Magnets: An Unusual Complication

Foreign body ingestion is frequently the cause of emergency visits in the pediatric population, and these cases are challenging to diagnose and manage. In particular, the ingestion of magnets is dangerous and can lead to serious complications and even death. Urgent endoscopic intervention or surgical exploration remains the best approach for removing multiple ingested magnets and preventing further injury to the gastrointestinal (GI) tract. We report a nine-year-old child with an adjustment disorder who developed a gastrocolic fistula following the deliberate ingestion of multiple magnets. The magnets were successfully retrieved after an emergency laparotomy, and the fistula was subsequently repaired.

Multicenter investigation of pediatric gastrointestinal tract magnets ingestion in China

Purpose

To describe the incidence and management of gastrointestinal tract Buckyball magnets ingestions in a multicenter Chinese pediatric patient population, and discuss the preventive measures.

Methods

Medical records of 74 pediatric patients from 9 large Chinese hospitals during the past 10 years, who were diagnosed as buckyball magnets ingestion and got invasive treatment, were retrospectively studied. The follow-up was through telephone and outpatient service to estimate the post-surgery condition. Information collection was through online questionnaire.

Results

Among the 74 cases, there were 50 boys (68%) and 24 girls (32%). The median age was 36 (interquartile range (IQR) 22–77) months, with a range of 7 months to 11 years, and it showed two peaks, the first between 1 and 3 years, and the second between 6 to 11 years. The annual case number showed a sharp increase over time, and the total case number in the last 2 years (2017 and 2018) showed a greater than 9-fold increase when compared with the first 2 years (2013 and 2014). The majority of ingestions were unintentional, with only 3 patients deliberately swallowing the Buckyball magnets. The median time of ingestion until the onset of emergent symptoms was 2 (IQR 1–5) days, and ranged from 4 h to 40 days. Twenty-one patients had no symptoms, and the remaining cases presented with abdominal pain, vomiting, fever, abdominal distension, excessive crying, melena, and the ceasing of flatus and defecation. Gastroscopy, colonoscopy, laparoscopic surgery and laparotomy surgery were performed in accordance with the algorithm from the North American Society of Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN). Procedural and operative findings included gastrointestinal mucosa erosion, ischemia and necrosis, perforation, and abdominal abscess, fistula and intestinal obstruction. The median number of Buckyball magnets ingested was 4 (IQR 2–8), with a range from 1 to 39. During the median follow-up period of 6 (IQR 1–15) months, 3 patients had intestinal obstruction, and one underwent a second operation. The remaining 71 patients courses were uneventful during the follow-up period. None of the 74 patients reported a second swallowing of foreign bodies.

Conclusions

The incidence of pediatric gastrointestinal tract magnets ingestion in China is increasing. Management of such patients should follow the NASPGHAN algorithm. Preventive measures to limit children’s access to Buckyball magnets should be taken from three levels, namely the national administration, producer, and consumer.

Multiple Magnet Ingestion leading to Bowel Perforation: A Relatively Sinister Foreign Body

Foreign body ingestion is a common reason for seeking emergency care among children. One of the more serious foreign bodies are the ingestion of multiple magnets or concurrent ingestion of a magnet and a metallic foreign body. Conservative management with serial imaging can be misleading in such cases. Multiple magnets tend to have strong attractive forces among them and may encase loops of bowel within them. Once entrapped, pressure necrosis and perforation will ensue, and thus, a low threshold should be adopted for surgical exploration in such cases. We present the case of a two-year-old male who had an accidental, unwitnessed ingestion of multiple magnets and also report the subsequent surgical management and associated morbidity.

Emergency Management of the Ingested Magnet: An Algorithmic Approach

INTRODUCTION

Accidental ingestion of foreign bodies is an increasing problem in the pediatric population. Symptoms are often nonspecific and may lead to a missed diagnosis because the ingestion event often goes unwitnessed.

CASE

We present a case of a missed diagnosis of a multiple magnet ingestion event in a pediatric patient leading to operative management. A 2-year-old boy with a 4-week history of nonspecific abdominal pain presented to the emergency department (ED) with vomiting and worsening abdominal pain. He was recently seen in the ED for nonspecific abdominal pain diagnosed as acute otitis media. In this second ED visit, the child was found to be febrile and tachycardic and had signs of peritonitis. Radiographs revealed a foreign body in the right lower quadrant. The child was taken to the operating room where multiple intestinal perforations were identified and repaired. The child had an uneventful postoperative course and was discharged 7 days later.

DISCUSSION

There are increasing awareness and growing concern over complications from pediatric magnet ingestion. Complications from neodymium magnet ingestion may include bowel obstruction, perforation, and fistula formation. The risk of complications is especially high with multiple-magnet ingestion. Pediatric foreign-body magnet ingestion may be a diagnostic challenge because the associated symptoms are nonspecific, and the ingestion is often unwitnessed.

CONCLUSIONS

Our case represents the missed diagnosis of 4 magnets ingested separately over time. Emergency department providers may benefit from a clinical algorithm guiding the management of these increasingly prevalent patient presentations to prevent delayed diagnoses and to decrease morbidity.

Foreign Body Removal in Children Using Foley Catheter or Magnet Tube from Gastrointestinal Tract

Foreign body (FB) ingestion of children is a common pediatric emergency requiring medical attention. Pediatric emergency physicians and gastroenterologists often encounter nervous and distressed situations, because of children presenting with this condition in the common clinical practice. When determining the appropriate timing and indications for intervention, physicians should consider multiple patient- and FB-related factors. The utilization of a flexible endoscopy is considered safe and effective to use in these cases, with a high success rate, for the effective extraction of FBs from the gastrointestinal tract of a child. Additionally, a Foley catheter and a magnet-attached Levin tube have been used for decades in the case of FB removal. Although their use has decreased significantly in recent times, these instruments continue to be used for several indications. Using a Foley catheter for this purpose does not require special training and does not necessarily require sedation of the patient or fluoroscopy, which serve as advantages of utilizing this method for foreign object retrieval. An ingested magnet or iron-containing FB can be retrieved using a magnet-attached tube, and can be effective to retrieve an object from any section of the upper gastrointestinal tract that can be reached. Simple and inexpensive devices such as Foley catheters and magnet-attached tubes can be used in emergencies such as with the esophageal impaction of disk batteries if endoscopy cannot be performed immediately (e.g., in rural areas and/or in patients presenting at midnight in a facility, especially in those without access to endoscopes or emergency services, or in any situation that warrants urgent removal of a foreign object).

Non-Surgical Management of Gastroduodenal Fistula Caused by Ingested Neodymium Magnets

Foreign body ingestions pose a significant health risk in children. Neodymium magnets are high-powered, rare-earth magnets that is a serious issue in the pediatric population due to their strong magnetic force and high rate of complications. When multiple magnets are ingested, there is potential for morbidity and mortality, including gastrointestinal fistula formation, obstruction, bleeding, perforation, and death. Many cases require surgical intervention for removal of the magnets and management of subsequent complications. However, we report a case of multiple magnet ingestion in a 19-month-old child complicated by gastroduodenal fistula that was successfully treated by endoscopic removal and supportive care avoiding the need for surgical intervention. At two-week follow-up, the child was asymptomatic and upper gastrointestinal series obtained six months later demonstrated resolution of the fistula.

Magnet foreign body ingestion: rare occurrence but big consequences

PURPOSE

To review the outcomes of magnet ingestions from two children's hospitals and develop a clinical management pathway.

METHODS

Children <18years old who ingested a magnet were reviewed from 1/2011 to 6/2016 from two tertiary center children's hospitals. Demographics, symptoms, management and outcomes were analyzed.

RESULTS

From 2011 to 2016, there were 89 magnet ingestions (50 from hospital 1 and 39 from hospital 2); 50 (56%) were males. Median age was 7.9 (4.0-12.0) years; 60 (67%) presented with multiple magnets or a magnet and a second metallic co-ingestion. Suspected locations found on imaging were: stomach (53%), small bowel (38%), colon (23%) and esophagus (3%). Only 35 patients (39%) presented with symptoms and the most common symptom was abdominal pain (33%). 42 (47%) patients underwent an intervention, in which 20 (23%) had an abdominal operation. For those undergoing abdominal surgery, an exact logistic regression model identified multiple magnets or a magnet and a second metallic object co-ingestion (OR 12.9; 95% CI, 2.4 - Infinity) and abdominal pain (OR 13.0; 95% CI, 3.2-67.8) as independent risk factors.

CONCLUSION

Magnets have a high risk of requiring surgical intervention for removal. Therefore, we developed a management algorithm for magnet ingestion.

Presentation and management of nasal foreign bodies at a tertiary children's hospital in an American metro area

OBJECTIVES

To examine rates of otolaryngology intervention in children presenting to our emergency department with nasal foreign bodies, factors associated with otolaryngology involvement, rates of complications, and details on nasal button battery exposure.

METHODS

All patients presenting with a nasal foreign body to Children's Hospital Colorado from 2007 to 2012 were identified. Factors leading to referral to otolaryngology and operative intervention were examined, as well as complications.

RESULTS

102 patients were included. 36 (35%) patients were referred to the otolaryngology clinic, of which 58.9% required operating room intervention. 66 (64.7%) children had their nasal foreign bodies removed in the emergency room, however 30 (45%) of these were removed by an otolaryngology resident or attending physician. Overall, 64.7% of nasal foreign bodies required removal by otolaryngology. Of the 15 objects removed in the operating room, six were button batteries. No septal perforations occurred as a result of nasal button battery exposure. Multivariable logistic regression showed two significant predictors of OR removal: age and disc shaped objects.

CONCLUSION

While emergency department providers are comfortable attempting removal of nasal foreign bodies, there was a high rate of otolaryngology intervention. Based on this data, there is a need to educate emergency room providers on nasal anatomy and techniques for nasal foreign body removal.
