Foreign bodies in the gastrointestinal tract

Sharp-Pointed Foreign Body Ingestion in Pediatric Age

OBJECTIVES

To assess the clinical complications reported after the ingestion of sharp/pointed foreign bodies (FBs) in pediatric age, their incidence among all FB ingestions, and the features and clinical presentation of children.

STUDY DESIGN

We have recruited all consecutive patients aged 0-14 years, admitted for sharp/pointed FB ingestion. Clinical data until hospital discharge were accurately recorded, including both children with esophagogastric FB retention who underwent endoscopic removal and children who were radiologically followed-up till spontaneous FB expulsion. Clinical outcomes were recorded for each patient, with special reference to possible prolonged retention and wall perforation during the intestinal passage.

RESULTS

We have enrolled 580 children (males/females: 292/288; age range: 11-180 months; mean age ± standard deviation: 50.5 ± 42 months). Sharp/pointed FBs mainly included fragments of metal 270 of 580 (46.55%) and glass 180 of 580 (31%). FBs were endoscopically removed in 79 of 580 (13.6%) children whereas the remaining FBs passed through the gastrointestinal tract over an overall mean time of 29 hours. No cases of intestinal perforation nor prolonged retention were observed. In 3 of 65 (4.6%) procedures the endoscopist faced an uncomfortable endoscopic removal due to the shape and size of the FB which hampered the retrograde passage through the esophageal sphincters.

CONCLUSIONS

Our original and extensive data emphasize that accidental ingestion of sharp/pointed FB ingestion is a current issue in pediatric age, especially in toddlers. Metal and glass objects are the most involved FBs and their endoscopic retrieval may not be easy in about 5% of cases. Fortunately, in our pediatric sample no surgical intervention was needed.

Technology Driven Newer Ingested Foreign Body: A Case Report

As technology advances there are chances of new hazards to health also increases. In the current era of the digitalized world using a smart electronic device may cause harm to the children. We reported a case of foreign body ingestion which is new in the field of ENT practice. A 1-year-old male child patient presents with an ingested foreign body memory card guard slot cover. To date, this is a newer one in all types of an old foreign body reported in ENT practice.

Body stuffing during apprehension resulting in distal esophageal impaction: a case report and review of the literature

Background

Body stuffing and body packing are two methods of concealing illicit drugs. Body stuffing is defined as the oral ingestion of illicit drugs, typically to avoid law enforcement detection or other consequences of possession, and may present a serious medical emergency in patients. Most commonly, body stuffers ingest possibly large or unknown quantities of illicit substances to avoid detection of the drugs during apprehension. This ingestion is typically hasty or impulsive, and therefore the substances ingested are rarely packaged in a way that would be considered safe for ingestion.

Case presentation

This case highlights a series of rare complications of impacted esophageal foreign body including esophageal edema, pericarditis, and hydro-pneumothorax for a 16-year-old Hispanic male who was booked into a county juvenile detention and rehabilitation facility. He complained of persistent intractable epigastric pain, along with pleuritic chest pain with multiple episodes of vomiting over the previous 4 days. He denied swallowing any foreign body. He underwent esophagogastroduodenoscopy, and a plastic bag with content suspicious for marijuana was discovered in the distal esophagus and removed.

Conclusions

Failure to consider body stuffing and foreign body impaction in individuals during medical evaluation in detention centers with complaints of chest pain, abdominal pain, dysphagia, and/or certain toxidromes can delay diagnosis and lead to a variety of medical complications.

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.

Anorectal emergencies: WSES-AAST guidelines

Anorectal emergencies comprise a wide variety of diseases that share common symptoms, i.e., anorectal pain or bleeding and might require immediate management. While most of the underlying conditions do not need inpatient management, some of them could be life-threatening and need prompt recognition and treatment. It is well known that an incorrect diagnosis is frequent for anorectal diseases and that a delayed diagnosis is related to an impaired outcome. This paper aims to improve the knowledge and the awareness on this specific topic and to provide a useful tool for every physician dealing with anorectal emergencies.The present guidelines have been developed according to the GRADE methodology. To create these guidelines, a panel of experts was designed and charged by the boards of the World Society of Emergency Surgery (WSES) and American Association for the Surgery of Trauma (AAST) to perform a systematic review of the available literature and to provide evidence-based statements with immediate practical application. All the statements were presented and discussed during the WSES-AAST-WJES Consensus Conference on Anorectal Emergencies, and for each statement, a consensus among the WSES-AAST panel of experts was reached. We structured our work into seven main topics to cover the entire management of patients with anorectal emergencies and to provide an up-to-date, easy-to-use tool that can help physicians and surgeons during the decision-making process.

How we do it: impacted oesophageal foreign body removal using a dilatation balloon

BACKGROUND

Ingested foreign bodies are a common presentation to paediatric ENT services. Depending on the site, these are usually managed with flexible or rigid oesophagoscopy and retrieval. This paper presents a novel technique for removing a hollow foreign body that could not be removed using conventional means.

METHOD AND RESULTS

After rigid and flexible approaches failed, a guidewire was passed through the foreign body under fluoroscopic guidance and a dilatation balloon passed through the lumen of the object. Inflating the balloon allowed dilatation of the inflamed mucosa above and below the object, facilitating straightforward removal under traction.

CONCLUSION

This is a novel and reproducible technique that uses equipment readily available in tertiary referral centres. Employed in this context, the technique enabled removal of an impacted object surrounded by granulation tissue, and would be appropriate for other objects with a lumen.

Intentional Ingestion of a Metallic Wire Causing Perforation and Retroperitoneal Abscess: A Case Report

Foreign body ingestion is a frequent condition, with the majority of foreign bodies (FBs) tending to spontaneously proceed along the gastrointestinal tract without any major complications. A wide range of procedures are available to remove FBs; however, a real challenge exists in managing sharp, rigid, and long foreign objects, which are related to higher rates of complications. A 34-year-old man who intentionally swallowed a metallic wire of 20 cm length, presented to our ED with abdominal pain 2 weeks after the ingestion. The FB had migrated to the stomach and duodenum. Complications included perforation of the duodenum and ascending colon and a retroperitoneal abscess. FB removal was done via laparotomy, followed by the repair of perforations and damaged tissues. This case highlights the complications of a FB presence in the gastrointestinal tract for 14 days and emphasizes the importance of urgent and appropriate management of such conditions.

The Importance of Autopsy in a Case of Digestive Perforation Undetected by Postmortem Computed Tomography

ABSTRACT

Cases of foreign body ingestion in the forensic literature are mainly described in children or psychiatric patients. Postmortem imaging can detect most foreign bodies, but its sensitivity depends, among other things, on the type of item and its location. In some cases, the ingestion of foreign bodies can remain unnoticed and have serious consequences for the patient. We describe the case of a patient who died in a psychiatric seclusion room with no obvious cause and for whom a forensic autopsy was requested. Further investigations showed the existence of a subdural hematoma associated with a midline shift, secondary to a skull fracture that was considered to be the cause of death. Toxicological analyses identified in blood several drugs, including diazepam (24 ng/mL) and its major metabolite nordazepam (24 ng/mL), propranolol (57 ng/mL), paliperidone (9 ng/mL), and loxapine (620 ng/mL). The forensic autopsy revealed the existence of a gastrointestinal perforation after the ingestion of a plastic teaspoon, which the postmortem CT scan had failed to detect. Although technological advances continue to assist the forensic pathologist in his diagnosis, autopsy still has a leading role in forensic investigations and does not yet seem to be replaceable by imaging techniques alone.

Factors affecting successful esophageal foreign body removal using a Foley catheter in pediatric patients

Objective

This study aimed to determine the factors that affect successful esophageal foreign body (FB) removal using a Foley catheter and to identify methods to increase the success rate.

Methods

In this retrospective, cross-sectional study, we included pediatric patients who presented with esophageal FB impaction that was removed using a Foley catheter in the emergency departments of tertiary care and academic hospitals. We analyzed the effect of the patients’ age, sex, and symptoms; FB type, size, and location; Foley catheter size; complications during FB removal; duration between FB ingestion and removal; operator’s years of training; sedation; success rate of FB removal; endoscopy; and patient’s posture during FB removal on the success of Foley catheter-based FB removal.

Results

Of the 43 patients we enrolled, Foley catheter-based FB removal was successful in 81.4% (35/43) but failed in 18.6% (8/43) of patients; no FB-removal-related complications were reported. There was no significant association between the success rate of Foley catheter-based FB removal and any study variable. A higher number of years in training tended to increase the success rate of Foley catheter-based FB removal, although statistical significance was not achieved.

Conclusion

Children’s esophageal FB removal is a practical challenge in the emergency rooms, and using a Foley catheter is associated with a high success rate of the removal and low occurrence of complications. In this study, no single variable was found correlated with the success rate of Foley catheter-based esophageal FB removal in pediatric patients, which may indicate multiple variables interacting with one another to affect the success rate.

Pediatric button battery ingestion: Publication trends in the literature

OBJECTIVE

Examine literature for evidence of changes in button battery (BB) research over time including: amount and rate of literature output, levels of evidence, and the location of the research.

METHODS

Literature review of all peer-reviewed button battery literature available online through Pubmed and Embase was performed. Inclusion criteria were applied to ensure relevance. Publications were grouped into 4 time periods. Various study characteristics were compared between groups.

RESULTS

A total of 255 original research studies were reviewed. A significant increase in study number was found with a 664% increase comparing 2009-2018 and 1977-1988 (p < 0.001) and a 187% increase comparing 2009-2018 and all previous years. Average author number significantly increased over the study period (range: 2.8 to 4.4; p < 0.001). Case report or case series were consistently the most common type of study design (range: 56.5% to 84.0%). Level of evidence has remained at 4-5 for the majority of studies (range: 87% to 92.1%). First author specialty remained stable over time, with non-otolaryngologist surgeons being the most common authors, followed by pediatricians and otolaryngologists (28.8%, 18.9%, 18.5%, respectively). Location of research has diversified, with US publications falling from 50% to 29.5% of all studies when comparing 1977-1988 to 2009-2018 time periods.

CONCLUSIONS

Button battery ingestion in the pediatric population has been an important topic of discussion among various medical specialties due to a rise in morbidity and mortality surrounding these ingestions. Despite the increase in number of studies and authors, the strength of these studies has remained largely unchanged.

Outcomes of delayed endoscopic management for esophageal soft food impactions

BACKGROUND AND AIMS

Food impactions are a common reason for emergent upper endoscopy. Current guidelines call for urgent upper endoscopy (within 24 hours) for food impactions without complete esophageal obstruction and emergent endoscopy (within 6 hours) for those with complete esophageal obstruction. Multiple adverse events can arise from esophageal foreign bodies. Cases with longer delays from symptom onset to presentation have been associated with higher rates of surgical intervention. However, data on esophageal soft food impactions are scant. We set out to determine differences in outcomes for food impactions undergoing intervention within 12 hours versus over 12 hours of symptom onset.

METHODS

A retrospective review of medical records was conducted to identify patients who presented to our hospital with an esophageal soft food impaction and underwent an EGD between January 2010 and January 2018. Patients were divided into 2 groups based on the timing from symptom onset to EGD. An EGD within 12 hours was considered an early intervention and over 12 hours was considered a delayed intervention. Patients who had ingested bones or hard objects were not included. Primary outcomes studied were rates of aspiration, admission, local esophageal adverse events, and 30-day all-cause mortality.

RESULTS

We identified 110 patients with a soft food impaction who underwent an EGD. Forty- two patients had an early intervention and 68 a delayed intervention. There were no differences in basic demographics and comorbidities. Additionally, there were no differences in rates of local esophageal adverse events, aspiration, admission, or 30-day mortality. Multivariate analysis revealed endoscopic accessory use was associated with increased odds of local esophageal adverse events (odds ratio, 6.37; P = .01).

CONCLUSIONS

The overall rates of serious adverse events in esophageal soft food impactions are low. Delayed intervention is not associated with increased adverse events or 30-day mortality compared with early intervention. However, accessory use is associated with higher adverse event rates.

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).

Handheld Metal Detector Screening for Metallic Foreign Body Ingestion in Children

Coins are the most common ingested metallic foreign bodies among children. The goal of this protocol is to assess the accuracy and feasibility of using a handheld metal detector to detect ingested metallic foreign bodies in children. We propose that by introducing handheld metal detector screening early in the triage process of children with high suspicion of metallic foreign body ingestion, the number of radiographs being ordered to localize the metallic foreign body can be reduced in this radio-sensitive population. The study protocol requires the screening of the participants for history of foreign body ingestion and exclusion of patients with respiratory distress or metallic implants. The patient changes to hospital gown and items that could contain metal like eyeglasses, earrings, pendants, and ornaments are removed. The patient is positioned in the center of the room away from other metallic interferences. The working status of the handheld metal detector is first confirmed by eliciting a positive audio-visual signal. Then the screening is done in an erect position with head in extension to expose the neck, from the level of the chin to the level of the hip joint, to cover the anatomical areas from neck to pelvis in a zig-zag manner both anteriorly and posteriorly. A positive audio-visual signal is carefully noted during the scanning for the presence of metallic foreign body. Relevant radiographs are ordered as per the area detected on the metal detector screening. The handheld metal detector was able to precisely identify all the coins among the ingested metallic foreign bodies in our study. The handheld metal detector could not consistently detect non-coin metallic foreign bodies. This protocol demonstrates the accuracy of handheld metal detector in the identification and localization of coins and coin like metallic foreign bodies.

Handheld Metal Detector for Metallic Foreign Body Ingestion in Pediatric Emergency

OBJECTIVE

Foreign body ingestion is a common problem for which children present to the emergency department. The most common ingested foreign bodies among children are coins. Metal detector is an equipment, which measures a change in inductance of a coil when an electroconductive material is placed near it and produces an audio-visual signal. The present study was conducted to determine the effectiveness and feasibility of HMD in the local Pediatric population.

METHODS

This was a prospective study conducted in the pediatric emergency department among children presenting with history of foreign body ingestion. The outcome measured was presence or absence of metallic foreign body detected on handheld metal detector examination.

RESULTS

During the study period, 36 patients with history of foreign body ingestion presented to the emergency department. Among these, 28 were metallic foreign body ingestions. Coins were the most common type of foreign body ingested. Among the metallic foreign bodies ingested, all the coins were accurately identified by the handheld metal detector. Non-coin metallic foreign bodies like metallic screw, needle and stapler pin were not identified by the handheld metal detector.

CONCLUSIONS

The study demonstrates that handheld metal detector can be safely and reliably used as a screening tool in the process of detecting ingested coins. The plain radiograph still appears to be superior as it accurately localizes sharp metallic objects as well as cell batteries (button batteries) which need to be detected early and removed in order to prevent complications. Handheld metal detector is an effective tool that can be used in the follow up of patients to confirm whether the coin like metallic foreign body has been expelled. Handheld metal detector examination is more sensitive than traditional X-ray examination to detect radiolucent metallic foreign bodies like aluminium.

Endoscopic management of foreign bodies in the upper gastrointestinal tract: An analysis of 846 cases in China

Foreign body ingestion is a relatively common occurrence, which may lead to morbidity and mortality. The aim of the present study was to report the experience of management of upper gastrointestinal foreign bodies by endoscopy in a large center. All patients who presented at the Department of Gastroenterology at Nanfang Hospital (Guangzhou, China) with complaints regarding upper gastrointestinal (GI) foreign body ingestion from December 1987 to December 2013. Hospital medical charts and endoscopic records were examined to evaluate etiology, treatment, and outcomes for these patients. A total of 846 patients were enrolled in the present study, from which foreign bodies were detected in 737 (87.1%) patients via X-ray or endoscopy. The objects most frequently ingested were bones (n=395, 53.6%). The detected foreign bodies were predominantly located in the cervical esophagus (n=325, 44.1%). Endoscopic foreign body extraction was successful in 92.5% of cases, whereas surgery was required in 6 patients. The most frequently used endoscopic accessory devices were retrieval forceps (n=480, 65.1%). The complication rate was 6.9%, including mucosal laceration (n=10) and others, all of which were managed conservatively. Associated GI diseases were reported in 74 (10.0%) patients, including postesophagectomy (n=34) and others. In conclusion, the endoscopic procedure was safe and effective for the removal of foreign bodies from the upper gastrointestinal tract, with a high success rate and low complication rate.

Ingestion of nine metallic nails with corrosive: what happened next?

A 20-year-old woman was brought to the surgery emergency department with the complaint of epigastric pain since 1 day following ingestion of multiple metallic nails with a cup full of toilet cleaner (corrosive acid) with a suicidal intention. Physical examination was essentially unremarkable, and the abdomen showed no signs of perforation peritonitis. X-rays of the abdomen showed multiple 'nail'-like radiopaque shadows in the abdominal cavity with no evidence of free gas under the domes of the diaphragm. A non-operative expectant management was pursued. The patient had passed all the sharps in stools without any complication and was discharged after 12 days. After 3 weeks, the patient presented with non-bilious vomiting. Further investigations revealed pyloric stenosis with no oesophageal luminal stenosis. To bypass the pyloric stenosis, a Billroth II gastrojejunostomy was performed. The postoperative period was uneventful, and the recovery was smooth.

Management of Ingested Hijab-Pin

BACKGROUND AND STUDY AIMS

Accidental swallowing of hijab (or turban) pin was reported mainly among adolescent girls. Current guidelines indicate emergent intervention endoscopy in case a long sharp object is found in the gastrointestinal tract. The aims of the current study are to present the results of an observational approach and to assess the need for intervention.

PATIENTS AND METHODS

A retrospective cohort study was conducted including all 5-18-year-old patients who presented with hijab-pin ingestion between 2003 and 2014. The need for intervention was assessed using both univariable and multivariable statistical analyses.

RESULTS

Two hundred three cases of hijab-pin ingestion were documented. In the majority of cases, the pin was observed in the stomach (137/203, 67.4%) upon arrival. Most pins that were located at the upper gastrointestinal tract (proximal to the ligament of Treitz) ejected spontaneously (120/169, 71%, Pv = 0.005). The absence of pin progression in an X-ray performed 12 h following presentation was significantly more frequent in the intervention group (46/51, 90%, Pv = 0.001).

CONCLUSIONS

In most cases, the outcome is spontaneous ejection from the digestive tract. However, if needle location remains unchanged on two consecutive X-rays, an endoscopic intervention is recommended.

Atypical Presentation of Multiple Foreign Body Ingestion

Foreign body ingestion is very common in childhood especially under 3 year of age. Pica syndrome is characterized by an appetite for substances that are largely non-nutritive. We present a 3-year old girl who presented to ER with symptoms and signs of intestinal obstruction.

Intestinal Perforation in Obstructed Umbilical Hernia due to Wedged Plum Seed

The foreign body ingestion is a rare cause of gastrointestinal perforation in children and is typically seen with sharp foreign bodies or button batteries. Herein, we report an 11-month old male baby who presented with obstructed umbilical hernia. Abdominal radiograph showed dilated small bowel loops, while ultrasonography and CT scan suggested presence of a foreign body. Laparotomy revealed obstructed umbilical hernia with a plum seed being stuck in the terminal ileum causing intestinal perforation. Resection and anastomosis of intestine was performed.

Retrospective Audit of the Management of Anal Insertion of Foreign Bodies: A Holistic Approach

Most patients with voluntary anal insertion of a foreign body (IFB) present to the emergency department and are then managed by the surgical team. This report reviews the medical literature on IFB and includes results of a chart review of operative logged interventions and clinically coded procedures for anal IFBs at a single acute hospital in the United Kingdom between May 2009 and September 2013. The objective was to establish the current practice in the management of anal IFB and update a framework for the initial workup, surgical procedure, and appropriate mental health intervention.

Gastrointestinal Tract Perforation in the Newborn and Child: Imaging Assessment

Gastrointestinal tract perforation can arise from various underlying etiologies ranging from congenital causes to ingested foreign bodies in the pediatric patient population. Imaging assessment in patients with suspected gastrointestinal tract perforation plays a central role in making the diagnosis and follow-up evaluation. This article reviews the more common etiologies of gastrointestinal tract perforation in pediatric patients, their imaging manifestations, and strategies for imaging assessment to assist the radiologist in arriving at a timely and accurate diagnosis.

Endoscopic Management of Foreign Bodies in the Upper Gastrointestinal Tract: An Evidence-Based Review Article

Gastrointestinal foreign bodies (FB) are comprised of food bolus impaction and intentionally or unintentionally ingested or inserted true FB. Food bolus impaction and true FB ingestion represent a recurrent problem and a true challenge in gastrointestinal endoscopy. More than 80-90% of the ingested true FB will pass spontaneously through the gastrointestinal tract without complications. However, in 10-20% of the cases an endoscopic intervention is deemed necessary. True FB ingestion has its greatest incidence in children, psychiatric patients and prisoners. On the other hand, food bolus impaction typically occurs in the elderly population with an underlying esophageal pathology. The most serious situations, with higher rates of complications, are associated with prolonged esophageal impaction, ingestion of sharp and long objects, button batteries and magnets. Physicians should recognize early alarm symptoms, such as complete dysphagia, distressed patients not able to manage secretions, or clinical signs of perforation. Although many papers are yearly published regarding this subject, our knowledge is mainly based on case-reports and retrospective series. Herein, the authors summarize the existing evidence and propose an algorithm for the best approach to FB ingestion.

Endoscopic foreign body removal in the upper gastrointestinal tract: risk factors predicting conversion to surgery

BACKGROUND/AIMS

Most foreign bodies of the upper gastrointestinal tract (UGIT) are successfully removed by endoscopic techniques without complications. However, some require conversion to surgery due to failure of endoscopic removal. The aim of this study was to analyze the risk factors predicting the need to convert to surgery after inability to endoscopically remove the foreign body.

PATIENTS AND METHODS

The medical records of 885 patients treated between January 2006 and March 2014 for suspected foreign bodies in the UGIT were retrospectively reviewed. Patient characteristics, the type of foreign bodies, clinical outcomes, and risk factors predicting the conversion to surgery were analyzed.

RESULTS

While endoscopic removal was successful in 94.7% (665/702) of the patients, the remaining 5.3% (37/702) needed conversion to surgery. There were no procedure-related deaths. According to the multivariate logistic regression analyses, older age (>70 years, p = 0.004), location (upper esophagus, p = 0.001), larger size (maximal diameter > 30 mm, p = 0.005), and longer impaction time (>40 h, p < 0.001) were significant risk factors predicting conversion to surgery due to inability to remove the foreign body endoscopically.

CONCLUSIONS

Most of the foreign bodies in the UGIT were successfully removed by endoscopic techniques. However, surgical removal might need to be considered in patients with age >70 years, and those with foreign bodies in the upper esophagus, maximal diameter >30 mm, and impaction time >40 h, due to the possible high failure rate of endoscopic removal.

A case of battery ingestion in a pediatric patient: what is its importance?

This is a case of a two-year-old boy who has been suffering from food regurgitation and frequent vomiting over the past seven months which were progressively worsening with time. He was initially diagnosed with gastroesophageal reflux disease and treated accordingly but responded only minimally. Investigations and interventional procedures including a chest X-ray showed a metallic round object in the upper esophagus consistent with a button battery which was removed via a thoracotomy after an esophagoscopy was not successful. This child would not have developed such serious complications and would not have required major surgery had the foreign body been identified and removed early on.

Role of plain radiography in the assessment of ingested foreign bodies in the pediatric patients

Ingestion of various types of foreign bodies (FBs) such as coins, toy parts, jewelry pieces, needles and pins, fish and chicken bones, and button-type batteries is common among children. The curiosity of children and their need to investigate the world around them place them at a higher risk for ingestion of FBs. Fortunately, 80%-90% of ingested foreign objects that reach the stomach will pass uneventfully without intervention. The remainder may become blocked in the esophagus or other region of the alimentary tract, placing the pediatric patient at risk of significant complications such as aspiration, obstruction, bleeding, perforation, fistulization, sepsis, and death. The goals of the initial pediatric patient assessment are to identify the type of object ingested, its location in the gastrointestinal tract, and the presence of associated complications. Factors reported to increase the risk of complications included a sharp FB, a FB with a wide diameter, and symptoms. Plain radiographs still play an important role in the assessment of ingested FBs in the pediatric patient: plain films of the neck, chest, and abdomen are very useful in confirming the diagnosis of FB ingestion because most ingested FBs are radiopaque.

Accidental Ingestion of a Grill Brush Wire Resulting in Death

Accidental ingestion of a foreign body is a rare occurrence in the unimpaired adult. The usual patient is aware of the ingestion event and seeks medical attention if needed.

We report a case of accidental, unrecognized, fatal ingestion of a foreign body discovered during a postmortem examination. In situ examination revealed a small perforation of the terminal ileum by a perforating metal wire. Fibrinopurulent peritonitis was the immediate cause of death. The foreign body was later found to closely resemble the wire bristles of a barbeque grill brush that family members brought to a family/clinician/pathologist conference.

There are few previous case reports of ingestion of a grill brush wire, all of which were nonfatal. Health care workers, including pathologists, should be aware of this potential ingestible foreign body given the widespread use of barbeque grills in food preparation. Additionally, manufacturers and users of grill brushes should be well aware of this ingestion hazard.

Yield of chest radiography after removal of esophageal foreign bodies

OBJECTIVES

The aim of this study was to determine the benefit of routine postoperative chest radiography after removal of esophageal foreign bodies in children.

METHODS

Medical records were reviewed of all patients evaluated with an esophageal foreign body at a single children's hospital over 10 years. Operative records and imaging reports were reviewed for evidence of esophageal injury.

RESULTS

Of 803 records identified, 690 were included. All underwent rigid esophagoscopy and foreign body removal. The most common items removed were coins (94%), food boluses (3%), and batteries (2%). The rate of esophageal injury was 1.3% (9 patients). No injuries were identified on chest radiographs done as routine or for concern of injury. Patients with operative findings suggestive of an esophageal injury (n = 105) were significantly more likely to have an injury (8.6% vs 0%, P = .0001). Of the 585 children who did not have physical evidence of injury, 40% (n = 235) received a routine chest radiograph. Regardless of the indication, no injuries were identified on chest films.

CONCLUSIONS

We conclude that intraoperative findings during rigid esophagoscopy suggestive of an injury are predictive of esophageal perforation. Routine chest radiography is not warranted in children who do not meet this criterion. In patients with a concern for injury, we suggest that chest radiography should be deferred in favor of esophagram.

A systematic review of paediatric foreign body ingestion: presentation, complications, and management

BACKGROUND

Foreign body ingestion is a common problem among paediatric populations. A variety of foreign bodies are ingested, some of which are particularly harmful and life threatening such as button batteries, magnets and bones. Common household items such as small toys, marbles, batteries and erasers are often ingested. The aim of this systematic review is to study the problem of foreign body ingestion among paediatric populations in terms of commonly ingested objects, and attempt to identify the link between location of impaction, associated symptoms, complications, spontaneous passage, methods and timing of removal.

METHODS

A literature search of multiple databases including PubMed, Embase, Current Contents Connect and Medline were conducted for studies on foreign body ingestions. Based on strict inclusion and exclusion criteria, 17 studies were selected. A qualitative review of these studies was then performed to identify commonly ingested foreign bodies, symptoms, signs and complications of foreign body ingestion, rates of spontaneous passage and methods of retrieval of the ingested objects.

RESULTS

Coins are the most commonly ingested foreign body. A variety of gastrointestinal symptoms such vomiting and drooling as well as respiratory symptoms such as coughing and stridor are associated with foreign body ingestion. The oesophagus, in particular the upper third, is the common site of foreign body obstruction. Objects in the stomach and intestine were spontaneously passed more frequently than at any other sites in the gastrointestinal system. Complications such as bowel perforations, infection and death are more commonly associated with ingestion of objects such as batteries and sharp objects such as bones and needles. Ingested objects are most commonly removed by endoscopic means.

CONCLUSION

Foreign body ingestion is a common paediatric problem. Batteries and sharp objects should be removed immediately to avoid complications while others can be observed for spontaneous passage. Endoscopy has a high success rate in removing ingested foreign bodies.

[Predictive factors of eosinophilic esophagitis in esophageal food bolus impaction]

BACKGROUND

Food bolus esophageal impaction is often the first symptom in patients diagnosed with eosinophilic esophagitis, representing a change in the epidemiology and management of this urgency.

AIM

To detect eosinophilic esophagitis predictive factors in patients with esophageal impaction due to food bolus.

METHODS

Patients seen for foreign body impaction were retrospectively analyzed. Epidemiologic characteristics, endoscopic findings, and impaction history were studied. The statistical analysis was carried out using the Student's t test and the chi square test and a logistic regression model.

RESULTS

Of the 131 patients, 65% were men and the mean age was 56 years. The endoscopic suspicion of eosinophilic esophagitis was the most frequent finding in patients with food bolus impaction (n=89); those patients that did not have histologic confirmation were excluded (n=7). The remaining patients (n=82) were divided into two groups: confirmed eosinophilic esophagitis (Group A) (n=18) and other endoscopic findings (Group B) (n=64). Group A presented with a lower mean age (36.47 vs. 64.45, P=.001) and a more frequent past history of impaction (38% vs. 6%, OR=15.70, 95% CI (3.60-62.50), P=.001) than Group B. Age and impaction history acted as predictors for eosinophilic esophagitis with 82% sensitivity, 80% specificity, and 84% diagnostic accuracy (P<.001).

CONCLUSIONS

Age and a history of impaction predict the presence of eosinophilic esophagitis in patients with food bolus impaction.

Role of imaging in the assessment of impacted foreign bodies in the hypopharynx and cervical esophagus

Impaction of foreign bodies in the upper digestive tract is a serious pathologic condition in ear, nose, and throat practice and is particularly common in children, prisoners, and psychiatric patients. Commonly found objects include fish bones, chicken bones, pieces of glass, dental prostheses, coins, and needles. The goals of the initial patient assessment are to identify the type of object, its location in the gastrointestinal tract, the presence of any associated complications, and the presence of any underlying esophageal conditions. Radiographic evaluation is helpful to confirm the location of foreign bodies and associated complications. Plain films of the neck and chest commonly will show the location of radiopaque objects, such as coins. Both anteroposterior and lateral views are necessary, as some radiopaque objects overlying the vertebral column may only be visible on the lateral view. Multidetector row computed tomography is superior to plain radiographs for the detection of pharyngoesophageal foreign bodies and provide additional crucial information for the management of complicated cases especially related to sharp or pointed ingested foreign bodies.

Approach to the diagnosis and management of retained rectal foreign bodies: clinical update

Retained rectal foreign body is not an uncommon condition, but reliable epidemiological data are not available. The diagnosis and management can present a significant challenge due to delayed presentation and the reluctance of the patients to provide details of the incident. The aim of the clinical evaluation is to identify the type, number, size, shape and location of the foreign body. Removal of retained rectal foreign bodies requires experience, with particular attention to different methods of extracting various objects. Most retained rectal foreign bodies can be successfully extracted transanally under appropriate anaesthesia and only a small proportion, mostly cases of perforation, overt peritonitis, pelvic sepsis or for failure of transanal extraction, will require open surgery or laparoscopy. It is mandatory to perform a proctosigmoidoscopy after anorectal foreign body removal to exclude bowel injury and ensure that the patient has not inserted more than one foreign body. Patients with mucosal abrasion, tears and oedema are to be admitted for a period of observation.

Successful endoscopic removal of a lighter swallowed 17 months before

The majority of ingested foreign bodies will pass safely through the gastrointestinal tract, but long and rigid foreign bodies are associated with an increased risk of gastrointestinal impaction, perforation and bleeding. However, large foreign bodies which have been swallowed can remain trapped in the stomach over a longer period of time without any significant symptoms. This case report describes the case of a 36-year-old man addicted to heroin who purposefully swallowed a lighter (double wrapped in cellophane) and presented with hematemesis and melena 17 months after the ingestion of the foreign body. The lighter was successfully removed via flexible endoscopy using a polypectomy snare. Swallowed long and rigid foreign bodies trapped in the stomach over a long period of time always represent a special clinical and endoscopic challenge. In cases where endoscopic removal fails, a laparoscopic surgical approach may be an alternative.

Risk factors for complications after a foreign body is retained in the esophagus

BACKGROUND

Foreign body (FB) ingestion is a common problem presenting to the emergency department (ED). The standard treatment, removal by endoscopy, is well established. However, some patients may refuse this invasive procedure due to their fear of an uncomfortable or painful experience. Obtaining hard evidence of potential complications of not having the FB removed by endoscopy would be helpful in convincing patients to have the procedure.

OBJECTIVES

The aim of this study was to identify the risk factors for developing complications after FB ingestion.

MATERIALS AND METHODS

The study was conducted over a period of 1 year (April 1, 2006 through March 31, 2007) at a referral medical center. Potential risk factors for developing complications (e.g., age, gender, type of FB, positive finding on radiography) were retrospectively evaluated in patients presenting with esophageal FBs and analyzed using chi-squared or Fisher's exact test and logistic regression.

RESULTS

A total of 225 patients were included. Fish bones were found to be the most common FBs (73.4%). The most commonly affected site was the oropharynx (64.5%). The complication rate was 9.7%. Risk factors for complications after FB ingestion were: 1) time interval over 24 h between FB ingestion and presenting to the ED; 2) a positive radiographic finding; 3) age > 50 years.

CONCLUSION

If a patient presents to the ED with at least one of the three risk factors identified, it is strongly suggested that the patient undergo endoscopy to remove the FB due to a higher risk for developing complications.

An interesting journey of an ingested needle: a case report and review of the literature on extra-abdominal migration of ingested foreign bodies

Swallowed foreign bodies encounter a major problem especially in children, but fortunately they mostly do not cause any related complication and are easily passed with the stool. In this paper, an interesting journey of a needle is presented. A 20-year old female admitted to our emergency service after she had swallowed a sewing machine needle, which is initially observed in the stomach in the plain abdominal radiography. During the follow-up period, the needle traveled through bowels, and surprisingly was observed in the left lung on 10^th day of the follow-up. It was removed with a thoracotomy and pneumotomy under the fluoroscopic guidance. The postoperative period was uneventful and the patient was discharged from the hospital on the day 5. We also review the literature on interesting extra-abdominal migrations of swallowing foreign bodies.
