Endoscopic management of foreign bodies in the upper gastrointestinal tract in South China: a retrospective study of 561 cases

Clinical features and endoscopic management of sharp wooden object ingestions: a systematic review of 479 cases

Background and aims

Ingested sharp objects pose increased risks of adverse events compared with other foreign bodies. We conducted the largest systematic review to date of sharp wooden object ingestions to elucidate patterns in clinical presentation and guide management practices.

Methods

Cochrane Library, Google Scholar, Ovid MEDLINE, Ovid Embase, PubMed, Scopus, and Web of Science Core Collection databases were searched for cases of adults who ingested sharp wooden objects. Descriptive statistics were reported for risk factors, clinical presentations, laboratory and imaging findings, adverse events, and treatments.

Results

Analysis of 479 cases showed that most patients were unaware of ingestion (74.8%) and toothpicks were the most common ingested item (92.5%). Male sex (70.1%), substance use (9.4%), and edentulousness (6.1%) were risk factors. Common symptoms included abdominal pain (83.7%) and fever (36.7%). Imaging identified the object in 48.1% of cases, with computed tomography being the most sensitive (54.7%). Objects were commonly found in the gastrointestinal tract (79.3%). They were consistently found in the gastrointestinal tract when patients were aware of ingestion or imaging showed an intraluminal/transluminal location. Endoscopy visualized the objects 76.1% of the time, with successful removal in 88.8% of cases; 4.7% of patients required surgery following endoscopic removal. Adverse events included perforation (87.5%) and abscess (33.0%), with a mortality rate of 5.0%.

Conclusions

Ingestion of sharp wooden objects presents heterogeneously and can lead to serious complications. Endoscopic removal is safe and effective. We propose a clinical algorithm to guide physicians in diagnosing and managing suspected sharp wooden object ingestion.

Recurrent neck Abscess by Migrating Fishbone Penetrating Thyroid Found in Subcutaneous Tissue: Case Report

Extraluminal foreign bodies are rare. Fish bone is the most common foreign body ingested by adults, while coin is the most common foreign body ingested among children. Sharp pricking pain is a sign of sharp foreign body (FB) ingestion. If the symptom persists, one should keep in mind the possibility of a migratory foreign body, even if the esophagoscopy results are negative. In order to ensure that foreign bodies are not missed radiologically, there is the role of consultation from a second radiologist to correlate with the patient's symptoms. Here we present an atypical case of recurrent neck abscess due to a migrating fishbone that penetrated the left thyroid lobe and settled in the left lower third neck subcutaneous tissue within two months.

Unforeseen consequences: A case report of misdiagnosis in pediatric ingestion of a fish bone

Children are frequently reported as cases of foreign body ingestion, with fishbone ingestion being particularly prevalent in communities where fish consumption is common. Although many instances of foreign body ingestion resolve spontaneously, the ingestion of sharp objects like fishbones poses a greater risk of morbidity and mortality due to their propensity for causing complications. Furthermore, incidents of foreign body ingestion often present with nonspecific symptoms or may go unnoticed, potentially leading to misdiagnosis and complicating the clinical course. We present a case of a 2-year-old boy initially misdiagnosed with constipation and treated with laxatives due to intermittent progressive abdominal pain. Subsequently, he presented to the emergency department where radiological and laboratory investigations revealed signs of inflammation and localized abdominal fluid collection containing a linear hyperdense object, indicating complicated foreign body ingestion with perforation. Urgent laparotomy revealed an omental abscess, which was excised, and the perforation site was repaired with sutures. This case underscores the risk of misdiagnosis and the importance of timely recognition and management. It also emphasizes the critical role of imaging, particularly computed tomography, in accurate diagnosis and differentiation from other common conditions.

Migrated toothpick causing a hepatic abscess with portal vein thrombosis: A case report and review of literature

Key Clinical Message

Accidental foreign body ingestion is the most common hidden cause of abdominal pain. A high index of suspicion should be implemented in patients with unresolved abdominal pain. Here we reported a 54-year-old patient with vague abdominal pain who had a successful laparoscopic removal of a toothpick.

Abstract

Toothpicks and fish bones are considered one of the most common accidentally ingested foreign bodies. Fortunately, most patients are asymptomatic. About 80%-90% of ingested foreign bodies pass through the gut spontaneously within a week. We present a case of a 54-year-old female with chronic epigastric pain and fever found to have a foreign body (toothpick) that penetrated the stomach and migrated to the liver causing liver abscess with portal vein thrombosis. The patient was managed with laparoscopic removal of the foreign body with an uneventful postoperative course.

Predicting Factors of Clinical Outcomes in Patients Hospitalized after Esophageal Foreign Body or Caustic Injuries: The Experience of a Tertiary Center

Ingestion of foreign bodies (IFB) and ingestion of caustic agents are frequent non-hemorrhagic causes of endoscopic urgencies, with the potential for severe complications. This study aimed to evaluate the predicting factors of the clinical outcomes of patients hospitalized as a result of IFB or ingestion of caustics (IC). This was a retrospective single-center study of patients admitted for IFB or IC between 2000 and 2019 at a tertiary center. Demographic and clinical data, as well as preliminary exams, were evaluated. Also, variables of the clinical outcomes, including the length of stay (LS) and other inpatient complications, were assessed. Sixty-six patients were included (44 IFB and 22 IC). The median LS was 7 days, with no differences between the groups (p = 0.07). The values of C-reactive protein (CRP) upon admission correlated with the LS in the IFB group (p < 0.01) but not with that of those admitted after IC. In the IFB patients, a diagnosis of perforation on both an endoscopy (p = 0.02) and CT scan (p < 0.01) was correlated with the LS. The Zargar classification was not correlated with the LS in the IC patients (p = 0.36). However, it was correlated with antibiotics, nosocomial pneumonia and an increased need for intensive care treatment. CT assessment of the severity of the caustic lesions did not correlate with the LS. In patients admitted for IFB, CRP values may help stratify the probability of complications. In patients admitted due to IC, the Zargar classification may help to predict inpatient complications, but it does not correlate with the LS.

Time trends and endoscopic management of foreign body ingestion in the upper GI tract: a retrospective analysis of 1,152 cases in China

OBJECTIVES

foreign body ingestions are encountered in the clinical practice and sometimes require endoscopic management. However, time trends and epidemiology of these cases have not been fully clarified. Whether seasons and festivals have an effect on the occurrence has been poorly described.

METHOD

from 2009 to 2020, 1,152 consecutive foreign body ingestion cases were enrolled in our endoscopic center. Case records were reviewed for demographic data, foreign body type and location, outpatient or hospitalization, adverse events and dates. Annual time trends and seasonal variation were analyzed as well as the influence of Chinese legal festivals on the incidence. The impact of SARS-CoV-2 pandemic on the potential delay for clinical consultation of these cases was preliminarily explored. Clinical features of these cases were demonstrated.

RESULTS

the overall success rate was 99.7 % and the adverse events rate was 2.4 %. There was an uptrend in the annual frequency of food foreign body ingestion endoscopic extraction from 0.65 in 2009 to 8.86 in 2020 per 1,000 esophagogastroduodenoscopy patients (r = 0.902, p < 0.001). Furthermore, the frequency of endoscopic extraction significantly increased in winter (p < 0.001) and during Chinese New Year celebratory season (p = 0.003). The duration of hospitalization may be longer in the pandemic period (p = 0.0049).

CONCLUSION

considering the uptrend of the annual frequency of food related foreign body endoscopic extraction, the publicity about the danger of foreign body ingestion should be enhanced. Arrangement of endoscopic physicians and assistants during the high-incidence season should be emphasized.

Accidental Sewing Pin Ingestion by a Tailor: A Case Report and Literature Review

Foreign body ingestion is a frequently encountered emergency in healthcare institutions. It mostly affects pediatric populations, although it can also affect adults with developmental delays, those with psychiatric diseases, drug abusers, and prisoners. Endoscopy is a diagnostic and treatment method for suspected foreign body ingestion. In this article, we discuss a 45-year-old tailor who swallowed a sewing pin while at work. The abdominal X-ray showed a needle-shaped metal shadow in the stomach region. During an upper endoscopy, it was discovered that a sewing pin with a sharp edge was stuck in the pylorus. The sewing pin was extracted endoscopically, and the patient was discharged the same day in good condition. Since the estimated risk of complications of foreign body ingestion in the adult population is about 35%, and the most common complications include impaction, laceration, bleeding, or perforation of the gastrointestinal wall, endoscopic or surgical removal is necessary. This also emphasizes the importance of a careful endoscopic evaluation of some at-risk occupations for foreign body ingestion with or without gastrointestinal complaints.

Cap-assisted endoscopy for esophageal foreign bodies: A meta-analysis

BACKGROUND

Esophageal foreign bodies are common around the world. Newer approaches, such as cap-assisted endoscopy, have been introduced as an alternative to conventional methods. Therefore, we performed a meta-analysis ono cap-assisted endoscopy versus conventional endoscopy for removal of esophageal foreign bodies.

AIM

To investigated the effectiveness of cap-assisted endoscopy with conventional endoscopy.

METHODS

An extensive literature search was performed (December 2021). For esophageal foreign body removal, cap-assisted endoscopy was compared to conventional endoscopy for procedure time, technical success of the procedure, time of foreign body retrieval, en bloc removal, and adverse event rate using odds ratio and mean difference.

RESULTS

Six studies met the inclusion criteria (n = 1305). Higher odds of technical success (P = 0.002) and en bloc removal (P < 0.01) and lower odds of adverse events (P = 0.02) and foreign body removal time (P < 0.01) were observed with cap-assisted endoscopy as compared to conventional techniques.

CONCLUSION

For esophageal foreign bodies, the technique of cap-assisted endoscopy demonstrated increased en bloc removal and technical success with decreased time and adverse events as compared to conventional techniques.

Navigating the Esophagus: Effective Strategies for Foreign Body Removal

Foreign body ingestion is a common medical emergency that can affect individuals of all ages and can be caused by various factors, including accidental ingestion, psychiatric disorders, intellectual disabilities, and substance abuse. The most common site for foreign body lodgment is the upper esophagus, followed by the middle esophagus, stomach, pharynx, lower esophagus, and duodenum. This article provides a case report of a 43-year-old male patient with a history of schizoaffective disorder and an indwelling suprapubic catheter who presented to the hospital due to foreign body ingestion. After examination, a metal clip from his Foley catheter was found lodged in his esophagus. The patient was intubated for the procedure, and an emergent endoscopic removal was performed to remove the metallic Foley component. No postoperative complications were observed, and the patient was successfully discharged. This case highlights the importance of considering foreign body ingestion in patients with chest pain, dysphagia, and vomiting. Prompt diagnosis and treatment are crucial to prevent potential complications such as perforation or gastrointestinal tract obstruction. The article also emphasizes the need for healthcare providers to know the different risk factors, variations, and common sites for foreign body lodgment to optimize patient care. Furthermore, the article highlights the importance of multidisciplinary care involving psychiatry and surgery to provide comprehensive care to patients with psychiatric disorders who may be at higher risk for foreign body ingestion. In conclusion, foreign body ingestion is a typical medical emergency that requires prompt diagnosis and treatment to prevent complications. This case report highlights the successful management of a patient with foreign body ingestion and emphasizes the importance of multidisciplinary care to optimize patient outcomes.

Cap-Assisted Endoscopic Esophageal Foreign Body Removal Is Safe and Efficacious Compared to Conventional Methods

INTRODUCTION

Esophageal foreign body impaction (FBI) is a commonly encountered gastrointestinal emergency requiring immediate intervention. Foreign bodies can be composed of food, commonly referred to as a "food bolus" (FB), or other matter (non-food). We aim to conduct systematic review and meta-analysis to compare cap-assisted and conventional endoscopic techniques for removal of esophageal FBI.

METHODS

A comprehensive search technique was utilized to identify studies that used capped endoscopic devices to remove FB or other esophageal foreign bodies. The primary outcomes were the technical success rate, rate of en bloc retrieval, and procedure time. Secondary outcomes were overall adverse events, bleeding, mucosal tears, and perforation.

RESULTS

Seven studies with a total of 1407 patients were included. The mean patient age was 55.3 (SD ± 7.2) years and 44.8% of patients were male. There were two RCTs and five observational studies among the included studies. The technical success rate was significantly higher in the cap-assisted group compared to the conventional group (OR 3.47, CI 1.68-7.168, I2 = 0%, p =  < 0.001), as well as the en bloc retrieval rate (OR 26.90, CI 17.82-40.60, I2 = 0%, p = 0.001). There was a trend towards lower procedural time for the cap-assisted group compared to the conventional group, although the difference did not reach statistical significance (MD - 10.997, CI - 22.78-0.786, I2 = 99.9%, p = 0.06). The overall adverse events were significantly lower in the cap-assisted group compared to the conventional group (OR 0.118, CI 0.018-0.792, I2 = 81.79%, p = 0.02).

CONCLUSION

The cap-assisted technique has improved efficacy and safety. To confirm these results, larger randomized trials are warranted.

Effect and Safety of Painless and Conventional Endoscopic Management of Denture Impaction in the Esophagus

Objective

To improve the level of clinical diagnosis and treatment, reduce the incidence of complications, and provide the basis for clinicians to choose an appropriate treatment, this research explores the removal methods of the impacted denture in the esophagus by endoscopy.

Methods

Based on the clinical information, treatment methods and complications of 72 patients with denture impaction in the esophagus admitted to our hospital from January 2016 to March 2021, which were divided into the group treated with painless endoscopy and the group treated with conventional endoscopy, retrospective analysis of the therapeutic effect and complications was conducted.

Results

There was no statistically significant difference between the two groups in terms of denture removal rate (P > 0.05). There were statistically significant differences between the two groups in terms of operating time and incidence rates of complications during and after the procedure. The operating time of the group treated with painless endoscopy was significantly shorter than the group treated with conventional endoscopy (P < 0.05). The incidence rates of complications during and after the procedure of the group treated with painless endoscopy were significantly lower than the group treated with conventional endoscopy (P < 0.05).

Conclusions

Compared with the conventional endoscopy, painless endoscopic management of denture impaction in the esophagus under general anesthesia with tracheal intubation improves the clinical efficacy and reduces the adverse reactions. Thus, it is worthy of clinical popularization and application.

Protocol of care for foreign-body ingestion in children: a qualitative study

OBJECTIVE:

This study aimed to suggest a care protocol for foreign-body ingestion, address the clinical aspects, and identify the ingested object, severity, and professional conduct.

METHODS:

This is a qualitative study. We used books and original articles published in national and international journals (BIREME, SCIELO, LILACS, and MEDLINE/PubMed) in Portuguese, Spanish, and English.

RESULTS:

The ingestion of a radiolucent object should be evaluated radiographically and with endoscopy for cases with symptoms of impaction and radiolucent objects. Coins are the most commonly involved foreign bodies. In asymptomatic patients, it often requires only a conservative form of management. Ingestion of batteries, magnets, and sharp objects carries a high risk of serious clinical complications and should have an endoscopic or surgical approach. In view of this, each pediatric emergency service, based on these recommendations, has the possibility to develop an individual protocol to identify and remove the ingested foreign body.

CONCLUSIONS:

Protocol of care for foreign-body ingestion in children depends on the object ingested, time of ingestion, symptoms, and local epidemiological context. This study provides some suggestions for decision-making in the conduct of health professionals.

A fatal perforation of the distal ileum from an ingested fish bone: A case report

INTRODUCTION AND IMPORTANCE

Foreign body-induced perforations of the ileum are rare consequences among adults.

PRESENTATION OF CASE

This is a case report of a delayed presentation of an ileal perforation and concurrent faecal peritonitis presented as an acute abdomen, resultant from an ingested fishbone, which led to fatality despite urgent laparotomy.

CLINICAL DISCUSSION

Perforations following ingested foreign bodies are frequently unanticipated clinically, and diagnosed during advanced imaging studies or surgical interventions. Endoscopy, laparoscopy, and laparotomy have been used during surgical management in reported cases; however, prior early identification is pivotal for good outcomes as delayed presentations and delayed diagnosis carry a poorer prognosis.

CONCLUSION

Despite fish bones being frequent foreign bodies in the gastrointestinal tract and the majority causing no life-threatening adverse effects, they are the leading foreign bodies instigating gastrointestinal perforations. A high degree of suspicion is required when attending to patients with suspected gastrointestinal perforations and absent typical findings in routine imaging, where fish bones could be the aetiology.

Incidence and evolution of foreign body impaction in the upper gastrointestinal tract and its relationship with eosionophilic oesophagitis

BACKGROUND

Foreign body impaction is a frequent indication of urgent endoscopy. One of the reasons for impaction is eosinophilic oesophagitis (EE). To analyze characteristics of oesophageal foreign body impactions and their relationship with eosinophilic oesophagitis.

METHODS

In this retrospective study, urgent endoscopies in a tertiary care centre were analyzed. We included all urgent endoscopies due to bolus and foreign body impactions performed between September 1st 2018 and September 1st 2020. We reviewed clinical data of all patients who were diagnosed with EE and compared it to impactions that were due to other motives. The mean follow-up time was 18.7 months.

RESULTS

693 urgent endoscopy procedures were performed. 239 (34%) of these were due to foreign body ingestion. Mean age of the patients was 63 years old and 135 (63%) were men. EE was diagnosed in 36 (17%) patients. The factors associated with EE were age, to be younger than 50 years (OR, 7.3; 95% CI, 1.1-48.4; p=0.04), asthma/rhinitis/atopic dermatitis (OR, 8.9; 95% CI, 2.3-35.3; p=0.002), findings in the endoscopy as trachealization (OR, 9.7; 95% CI, 1.3-70.9; p=0.03) and psychotropic/calcium channel blocker drugs (OR, 0.09; 95% CI, 0.009-0.9; p=0.04). 15 (7%) patients died. In 6 of them death was impaction-related. None patients with EE died.

CONCLUSIONS

Foreign body impaction in the upper gastrointestinal tract due to EE is a frequent cause of urgent endoscopy. Being under 50 years of age, having asthma/rhinitis/atopic dermatitis, trachealization on the oesophagus and not taking psychotropic/calcium channel blocker drugs are factors associated with the diagnosis of EE. Mortality in the follow-up of patients without EE is important.

Rigid versus flexible endoscopy for managing ingested foreign bodies-can we improve pathways?

PURPOSE

This study aims to evaluate management pathways, outcomes and safety of rigid endoscopy (RE) and flexible endoscopy (FE) for the treatment of impacted foreign bodies of the upper gastrointestinal tract (UGIT) in adults.

METHODS

Retrospective study, included all patients undergoing RE or FE for impacted UGIT foreign body over an 11-year-period.

RESULTS

A total of 144 patients were included (95 FE and 49 RE). FE were performed under local anaesthetic or sedation, and RE under GA. Success rate of FE and RE were 95.8% and 95.9% respectively. During FE an intra-procedural biopsy was performed in 45/95 (47.3%); with 26/95(27.4%) identifying mucosal pathology. Complications was significantly higher in patients having RE (40.8% versus 6.3%, p = .001).

CONCLUSION

FE and RE are effective for the therapeutic management of impacted UGIT foreign bodies. However, FE can be performed under LA and was associated with fewer complications, favouring FE where possible as a first line option.

Endoscopic Retrieval of Ingested Foreign Bodies: A Single Surgeon Experience

Introduction

Foreign body (FB) ingestion either accidental or intentional is a common clinical scenario encountered by general surgeons. This article reports a single surgeon's experience of endoscopic retrieval of foreign bodies from the upper gastrointestinal (UGI) tract.

Methods

A retrospective analysis of data of all the patients who underwent endoscopic management for foreign body removal by a single surgeon in a tertiary care hospital in southern India between 2015 and 2020 was conducted. Patient variables in terms of age, sex, type of foreign body, its location in the gastrointestinal (GI) tract, the time between ingestion and presentation, the time between presentation and endoscopy, treatment outcomes were reviewed.

Results

A total of 97 patients were studied. The age range of the patients studied was one month to 71 years. Males were predominant (n=64, 65.97%). The most common retrieved foreign body were coins (n=31, 31.9%). The most common site of foreign body lodgment was the esophagus (n=75, 77.31%), with the upper third esophagus (n=38; 39.37%) being the predominant site. The success rate of endoscopic retrieval in our study was 97%. No procedure-related complications were encountered in any patient. Endoscopic management failed in two patients who ultimately required surgical intervention.

Conclusion

Endoscopic retrieval of foreign bodies in the UGI tract is a safe and effective modality. Early endoscopy in such patients avoids surgical intervention and reduces morbidity.

Comparison of Cap-Assisted vs Conventional Endoscopic Technique for Management of Food Bolus Impaction in the Esophagus: Results of a Multicenter Randomized Controlled Trial

INTRODUCTION

"Push" or "pull" techniques with the use of snares, forceps, baskets, and grasping devices are conventionally used to manage esophageal food bolus impaction (FBI). A novel cap-assisted technique has recently been advocated to reduce time taken for food bolus (FB) removal. This study aimed to compare the effectiveness of the cap-assisted technique against conventional methods of esophageal FB removal in a randomized controlled trial.

METHODS

Consecutive patients with esophageal FBI requiring endoscopic removal, from 3 Australian tertiary hospitals between 2017 and 2019, were randomized to either the cap-assisted technique or the conventional technique. Primary outcomes were technical success and FB retrieval time. Secondary outcomes were technical success rate, en bloc removal rate, procedure-related complication, length of hospital stay, and cost of consumables.

RESULTS

Over 24 months, 342 patients with esophageal FBI were randomized to a cap-assisted (n = 171) or conventional (n = 171) technique. Compared with the conventional approach, the cap-assisted technique was associated with (i) shorter FB retrieval time (4.5 ± 0.5 minutes vs 21.7 ± 0.9 minutes, P < 0.001), (ii) shorter total procedure time (23.0 ± 0.6 minutes vs 47.0 ± 1.3 minutes, P < 0.0001), (iii) higher technical success rate (170/171 vs 160/171, P < 0.001), (iv) higher rate of en bloc removal (159/171 vs 48/171, P < 0.001), and (v) lower rate of procedure-related mucosal tear and bleeding (0/171 vs 13/171, P < 0.001). There were no major adverse events or deaths within 30 days in either group. The total cost of consumables was higher in the conventional group (A$19,644.90 vs A$6,239.90).

DISCUSSION

This multicenter randomized controlled trial confirmed that the cap-assisted technique is more effective and less costly than the conventional approach and should be first-line treatment for esophageal FBI.

Clinical outcomes of endoscopic removal of foreign bodies from the upper gastrointestinal tract

Background

Ingested foreign objects frequently require emergency removal. This study aimed to investigate the clinical outcomes of endoscopic removal of foreign bodies from the upper gastrointestinal tract and the risk factors for adverse events.

Methods

Adults (> 18 years) who underwent endoscopic management of ingested foreign bodies at two centers, one inland and one on the coast, between January 2008 and December 2017 were eligible. Clinical characteristics and procedure-related outcomes were retrospectively reviewed. Patients were divided into two groups, based on whether the foreign bodies were sharp or blunt in shape.

Results

A total of 853 patients aged 19–96 years were analyzed. Ingestion of fish bones was more common in the coastal area, whereas ingestion of food boluses was more common in the inland area. The duration of impaction ranged from 1 h to over 1 month and was significantly longer in patients who ingested blunt than sharp foreign bodies (15 vs. 5 h, p < 0.001). Most (98.9%) foreign bodies were successfully removed. Adverse events occurred in 31.2 % of patients, including ulcers (4.0%) and perforations (3.3 %). Multivariate analysis showed that age (odds ratio [OR] 1.015, p = 0.012), sharp foreign bodies (OR 5.133, p < 0.001), location in the esophagus (OR 2.723, p = 0.018), and duration of impaction (OR 1.431, p < 0.001) were factors associated with adverse events.

Conclusions

Early recognition and timely endoscopic removal of ingested foreign bodies, particularly in elderly patients and those with sharp foreign bodies, may improve clinical outcomes.

Characteristics of fish-bone foreign bodies in the upper aero-digestive tract: The importance of identifying the species of fish

BACKGROUND

Fish bones are common foreign bodies in the upper aero-digestive tract, but their clinical features in relation to fish species have not been confirmed. We aimed to clarify the clinical characteristics of fish-bone foreign bodies and their location and removal methods depending on the fish species.

STUDY DESIGN

Retrospective, observational, monocentric study.

METHODS

From October 2015 to May 2020, 368 patients visited the Department of Otolaryngology-Head and Neck Surgery at Tohoku University Hospital complaining of dysphagia, sore throat, or pharyngeal discomfort after eating fish. We analyzed the patients' sex and age distribution, foreign-body location, type of the fish, and the techniques used for removing the foreign body.

RESULTS

Fish bones were confirmed in the upper aero-digestive tract in 270 cases (73.4%), of which 236 (87.4%) involved fish-bone foreign bodies in the mesopharynx. The most frequently involved site was the palatine tonsil (n = 170). Eel was the most frequently observed fish species (n = 39), followed by mackerel (n = 33), salmon (n = 33), horse mackerel (n = 30), and flounder (n = 30). Among the 240 cases in which the bones did not spontaneously dislocate, 109 (45.4%) were treated by endoscopic removal (103 cases) or surgery (6 cases). In pediatric cases (<12 years old), almost all fish bones were found in the mesopharynx (138/139, 99.3%), and 31 cases (22.3%) required endoscopic removal. Flounder fish bones were often lodged in the hypopharynx and esophagus (9/30, 30%), hindering spontaneous dislocation and frequently necessitating endoscopic or surgical removal (19/29, 65.5%).

CONCLUSION

The characteristics of fish-bone foreign bodies differed depending on the fish species. Flounder bones were often stuck in the hypopharynx and esophagus and were likely to require more invasive removal methods. Confirming the species of the fish could facilitate appropriate diagnosis and treatment of fish-bone foreign bodies.

Retrospective Analysis of Esophageal Foreign Body Ingestion: Differences Among Weekday, Weekends, and Holidays

Purpose

Current data on the occurrence of EFBs in relation to different time periods are scant. The purpose of this study was to compare the occurrence, type and location of EFBs in people who presented at our center on weekdays, weekends and holidays.

Patients and Methods

A retrospective analysis of patients (n=1353) received rigid esophagoscopy for foreign body extraction under general anesthesia from January 2018 to 2020 December.

Results

The occurrence of EFB ingestion was significantly higher (p<0.05) on holidays (2.75/day) than on weekdays (0.91/day) and weekends (1.46/day). Patients were much older on holidays, with a mean age of 58.18 ± 17.34 years, than patients on weekdays (54.71 ± 16.71 years) and weekends (55.05 ± 17.36 years).

Conclusion

Our findings demonstrate that EFB ingestion is most likely to occur on weekends and holidays, and elderly patients should be advised to chewing slowly and eating non-nuclear jujube, especially during holidays, to minimize their risk.

Clinical presentation, diagnosis and management of aerodigestive tract foreign bodies in the adult population: Part 1

In the adult population, foreign bodies may be accidentally or intentionally ingested or even inserted into a body cavity. The majority of accidentally ingested foreign bodies pass through the alimentary tract without any complications and rarely require intervention. Accidentally ingested foreign bodies are usually fish bones, bones of other animals, and dentures. Oesophageal food impaction is the commonest cause of oesophageal foreign bodies in the Western hemisphere. Intentionally ingested foreign bodies may be organic or inorganic, and often require intervention; these patients have either underlying psychological or mental disease or are involved in illegal activities such as body packing, which involves trafficking narcotics. Imaging plays a crucial role in not only identifying the type, number and location of the foreign body but also in excluding any complications. In this comprehensive pictorial review, we provide an overview of the spectrum of foreign bodies ingested in adults, emphasising the role of various imaging modalities, their limitations and common foreign body mimickers on imaging.

Migration of ingested sharp foreign body into the bronchus: a case report and review of the literature

Background

Foreign body ingestion is a common emergence in gastroenterology. Foreign bodies are most likely to be embedded in the esophagus. The sharp ones may penetrate the esophageal wall and lead to serious complications.

Case presentation

A 72-year-old Chinese female was admitted to our hospital with a 4-day history of retrosternal pain and a growing cough after eating fish. Chest computed tomography scan indicated that a high-density foreign body (a fish bone) penetrated through the esophageal wall and inserted into the left main bronchus. First, we used a rigid esophagoscope to explore the esophagus under general anesthesia. However, the foreign body was invisible in the side of the esophagus. Then, the fiberoptic bronchoscopy was performed. We divided the fish bone, which traversed the left main bronchus, into two segments under holmium laser and removed the foreign body successfully. The operation time was short and there were no complications. The patient was discharged 1 week postoperatively and was symptom free even under a liquid diet.

Conclusions

There are several challenges in the management of this rare condition. We applied the technique of interventional bronchoscopy to the management of esophageal foreign body flexibly in an emergency. A surgery was avoided, which was more invasive and costly.

The removal of foreign body ingestion in the upper gastrointestinal tract: a retrospective study of 1,182 adult cases

Background

Foreign body (FB) ingestion in the gastrointestinal tract is a common and urgent problem observed in children and adults. However, there may be difficulty locating FBs and complications associated with their removal. This study aimed to identify risk factors and complications correlated to the presence and removal of FBs.

Methods

This 5-year retrospective study enrolled 1,311 patients between June 2014 and April 2019. Demographic and endoscopic data were collected, containing age, gender, types and location of FBs, duration of FB ingestion, accessory devices, endoscopic methods, and complications. Logistic regression analysis was applied to evaluate the predictive risk factors.

Results

Among 1,131 patients, FBs were found in 90.16% of cases. A major predictor for the presence of FB was a presentation of less than 24 hours (h). The types of FBs were jujube pits (36.72%) and fish bones (22.00%), and over 80% of the FBs were discovered in the esophagus. Complications were found in 239 cases (20.22%), of which hemorrhage (162/239, 67.78%) was the most frequent. Age ≥60, duration ≥24 h, and FBs ingested in the esophagus were considered as risk factors for developing complications.

Conclusions

In conclusion, the longer duration, age ≥60, and impaction in the esophagus were risk factors for developing complications following the ingestion of FBs. These factors should be considered when developing assessment and treatment plans in the management of FB ingestion.

Migration of fish bones into abdominal para-aortic tissue from the duodenum after leading to duodenal perforation: a case report

Background

Migration of fish bones into abdominal para-aortic tissue after penetrating the junction of 3rd and 4th part of duodenum is incredibly rare.

Case presentation

A 68-year-old man was admitted to our hospital with persistent colic in the lower abdomen after eating fish two weeks ago. Abdominal computed tomography (CT) scan showed High density streaks along the anterior and lower edges of the 3rd part of duodenum with peripheral exudation and localized peritonitis. Esophagogastroduodenoscopy didn’t find foreign bodies and perforations in the digestive tract. Laparoscopic surgery and intraoperative endoscopy were made to detect foreign bodies and perforation site was found. After transition to open surgery, the fish bone was found in abdominal para-aortic tissue and removed without complications. Postoperative recovery is smooth, and the patient resumed normal diet and was discharged.

Conclusions

It is difficult to choose a treatment plan for foreign bodies at the 3rd part of the duodenum, because it is difficult to judge the damage caused by the foreign body to the intestine and the positional relationship with the surrounding important organs. Conservative treatment or surgical treatment both have huge risks. The handling of this situation will extremely test the psychology, physical strength and professional experience of the surgeon.

Endoscopic management of foreign bodies in the gastrointestinal tract: A retrospective study of 109 cases

BACKGROUND

The ingestion of foreign bodies in the gastrointestinal tract is commonly encountered in clinical practice. Reports on individualized endoscopic removal of gastrointestinal foreign bodies are scarce.

AIM

To explore the method of individualized endoscopic removal of indigested foreign bodies in the gastrointestinal tract to improve the success rate of foreign body endoscopic removal.

METHODS

The clinical data of patients with digestive tract foreign bodies treated at the Third Medical Center of PLA General Hospital (former General Hospital of Armed Police Forces) from July 2014 to April 2019 were retrospectively analyzed.

RESULTS

One hundred and nine patients were included in the study, including 46 men (42.2%) and 63 women (57.8%). Their age ranged from 11 to 88 years, with an average age of 57.3 years; 52 cases (47.7%) were elderly. The most common type of foreign body was jujube kernel (53 cases, 48.6%), followed by fish bone (24 cases, 22%) and food mass (15 cases, 13.8%). The most common location of foreign bodies in the digestive tract was the esophagus (84 cases, 76.9%), followed by the colon (7 cases, 6.4%), anastomosis (6 cases, 5.5%), stomach (5 cases, 4.5%), and duodenum (2 cases, 1.8%). Pharynx foreign bodies can be directly removed with foreign body forceps, with the shortest time taken (average, 2.5 ± 0.7 min). For esophageal foreign bodies, foreign body forceps were used to clamp one end of the foreign bodys, exert to the opposite side, make it leave the mucous membrane and parallel to the lumen, and then remove. The foreign body in the upper part of the esophagus can be added with a casing or transparent cap. The foreign body in the lower esophagus can be pushed into the stomach and then removed under the endoscope. The average time taken for removal of foreign bodies in the upper, middle, and lower esophagus was 7.0 ± 5.3, 8.3 ± 6.3, and 3.3 ± 1.2, respectively. Anastomosis foreign bodies were often removed using a trap, and the average time taken was 6.2 ± 4.1 min. When removing the foreign body in the stomach, appropriate instrument should be selected according to the shape of the foreign body. In order to avoid scratching the mucosa by the tip of the foreign body, a transparent cap or a self-made protective device can be used. The average time used was 8.4 ± 1.7 min. Duodenal foreign body was usually dragged into the stomach tbefore removal, and the average time taken was 9.2 ± 3.1 min. Colonic foreign bodies mainly occurred in the sigmoid colon and were very difficult to remove. A clamp was usually used to clamp one end of the foreign body, exert to the opposite side, cause it to be parallel to the intestinal lumen, and then remove. The longest time was taken for colonic foreign bodies, with an average time of 15.6 ± 8.0 min. The success rate of endoscopic removal of foreign bodies in the digestive tract was 97.2% (106/109).

CONCLUSION

Individualized endoscopic removal of gastrointestinal foreign bodies is a safe and effective method.

Foreign Body and Caustic Substance Ingestion in Childhood

Foreign body and caustic substance ingestion in childhood are common and require accurate and timely diagnosis to provide appropriate management consistent with the ingested substance/foreign body and clinical presentation as well as the associated risk status to prevent significant complications and morbidity. The aim of this paper was to present foreign body and caustic ingestion in childhood in terms of epidemiology, pathophysiology, diagnostic work-up and appropriate management and potential complications in accordance with clinical presentation and the type of ingested substance/foreign body.

Misdiagnosis of peripheral abscess caused by duodenal foreign body: a case report and literature review

Background

The induction of chronic inflammation, perforation, and abscess by foreign bodies (FBs) in adults is uncommon. We present a delayed diagnosis case for a patient who had a fishbone stuck in the duodenal bulb, resulting in chronic abdominal pain for nearly 3 months. We present the diagnosis and treatment procedures for chronic patients, which differ from those for acute and emergency FB ingestion, and also summarize the characteristics of such patients through a systematic literature review.

Case presentation

A 68-year-old woman was brought to our hospital with repeated right upper abdominal pain lasting for 3 months and aggravation for 9 h. Computed tomography (CT) showed a streaky high-density shadow (approximately 3 cm in length) on the posterior wall of the gastric antrum extending outside the wall. Endoscopic ultrasonography showed hyperechoic space with a cross-section of approximately 0.1 × 0.1 cm in the deep submucosal layer of the local stomach, accompanied by an acoustic shadow in the rear. The possibility of a fishbone as well as perforation was considered and the object was removed using FB forceps. Fasting as well as acid inhibition and anti-infection medication were prescribed for the patient. She eventually recovered and was discharged from the hospital.

Conclusion

Endoscopic intervention can be recommended as the first option for patients with gastrointestinal FBs.

Evaluation of the medical economics and safety: two methods for the endoscopic removal of jujube pits

OBJECTIVE

to evaluate the medical economics and safety of two methods for the endoscopic removal of jujube pits, one with a transparent cap combined with a stone basket and the other with a transparent cap combined with foreign body forceps.

METHODS

consecutive patients with a suspected jujube pit ingestion in the esophagus between January 2008 and December 2017 were enrolled into the study. Fifty-three patients who met the criteria were divided into two groups. Group A patients were treated by a transparent cap combined with a stone basket and group B patients were treated by a transparent cap combined with foreign body forceps. The following clinical data were collected: age, sex, location of jujube pits, complications, operation time, extraction success and average hospital costs.

RESULTS

a total of 53 patients who met the criteria were enrolled into the study; 29 cases in group A and 24 cases in group B. Endoscopic removal was successful in 98.1% (52/53) of the patients and the remaining 1.9% (1/53) required surgery. Severe complications were less frequent in group A than in group B (p = 0.017). Surgery time was not significantly different between the two groups (p = 0.647). The extraction success in group A was higher than in group B (p = 0.001). The medical costs including the total cost, inspection, treatment, radiation and drug cost were not significantly different between the two groups (p > 0.05 in all cases).

CONCLUSION

endoscopic baskets are suitable for cases of jujube pit ingestion and have a higher extraction success and a lower proportion of severe complications. Surgery time was not significantly extended and the medical costs did not increase.

Endoscopic removal of foreign bodies: A retrospective study in Japan

BACKGROUND

The ingestion of foreign bodies (FBs) and food bolus impaction (FBI) in the digestive tract are commonly encountered clinical problems. Methods to handle such problems continue to evolve offering advantages, such as the avoidance of surgery, reduced cost, improved visualization, reduced morbidity, and high removal success rate. However, to date, no studies have evaluated the endoscopic management of FBs in Japan.

AIM

To elucidate level of safety and efficacy in the endoscopic management of FBs and FBI.

METHODS

A total of 215 procedures were performed at Keio University Hospital between November 2007 and August 2018. Data were collected from medical charts, and endoscopic details were collected from an endoscopic reporting system. Procedures performed with a flexible gastrointestinal endoscope were only taken into account. Patients who underwent a technique involving FB or FBI from the digestive tract were only included. Data on patient sex, patient age, outpatient, inpatient, FB type, FB location, procedure time, procedure type, removal device type, success, and technical complications were reviewed and analyzed retrospectively.

RESULTS

Among the 215 procedures, 136 (63.3%) were performed in old adults (≥ 60 years), 180 (83.7%) procedures were performed in outpatients. The most common type of FBs were press-through-pack (PTP) medications [72 (33.5%) cases], FBI [47 (21.9%)], Anisakis parasite (AP) [41 (19.1%) cases]. Most FBs were located in the esophagus [130 (60.5%) cases] followed by the stomach [68 (31.6%) cases]. AP was commonly found in the stomach [39 (57.4%) cases], and it was removed using biopsy forceps in 97.5% of the cases. The most common FBs according to anatomical location were PTP medications (40%) and dental prostheses (DP) (40%) in the laryngopharynx, PTP (48.5%) in the esophagus, AP (57.4%) in the stomach, DP (37.5%) in the small intestine and video capsule endoscopy device (75%) in the colon. A transparent cap with grasping forceps was the most commonly used device [82 (38.1%) cases]. The success rate of the procedure was 100%, and complication were observed in only one case (0.5%).

CONCLUSION

Endoscopic management of FBs and FBI in our Hospital is extremely safe and effective.

The role of a transparent cap in the endoscopic removal of foreign bodies in the esophagus: A propensity score-matched analysis

OBJECTIVE

To investigate the effectiveness and safety of transparent cap-assisted endoscopy in removing foreign bodies in the esophagus.

METHODS

Patients with foreign body lodged in the esophagus who received a transparent cap-assisted or conventional endoscopy between October 2004 and July 2018 were retrospectively enrolled. Propensity score matching was performed. The success rate of the endoscopic procedure, procedure time, clearness of endoscopic view and adverse event rate were compared between the two groups.

RESULTS

Of the 838 patients who had a foreign body lodged in the esophagus, 728 (86.9%) underwent endoscopic intervention. After matched by prospensity score, 224 patients each received either transparent cap-assisted endoscopy or conventional endoscopy. No difference was noted between the two groups in terms of the success rate (100% vs 99.1%, P = 0.499). Transparent cap-assisted endoscopy was associated with shorter procedure time for removing jujube pits ([4.24 ± 2.81] min vs [7.62 ± 8.15] min, P = 0.001), fish bones ([2.99 ± 2.15] min vs [6.49 ± 6.54] min, P < 0.001) and other sharp objects ([4.29 ± 3.36] min vs [10.60 ± 19.79 min], P = 0.027) and higher rates of clear endoscopic views in extracting jujube pits, fish bones, poultry bones and other sharp objects (98% vs 43.4%, 97.5% vs 74.1%, 100% vs 81.3% and 100% vs 82.7%; all P < 0.05). No significant differences in the rates of adverse event were observed between the groups (P = 1.000).

CONCLUSION

Transparent cap-assisted endoscopic technique is effective and safe for removing sharp foreign bodies in the esophagus.

Role of endoscopic transparent cap in managing pediatric foreign bodies in the entrance of the esophagus in a waking state

Background

This study aims to investigate the effect and safety of a gastroscope plus transparent cap in treating pediatric foreign bodies in the entrance of the esophagus in a waking state.

Methods

A total of 47 pediatric cases with foreign bodies were randomly divided into two groups: transparent cap group (24 cases), and the control group (23 cases). In the former group, one transparent cap was first installed on top of the gastroscope. Then, the foreign body was extracted using the gastroscope with a transparent cap in a waking state. In the other group, the foreign body was extracted using a gastroscope without a transparent cap in a waking state. Then, the time of extracting the foreign body, the success rate of extracting the foreign body and complication rate were compared between these two groups.

Results

The time of extraction in the transparent cap group was 6.78±1.76 min, which was obviously shorter than that of the control group (11.41±4.12 min, P<0.05). In addition, the success rate of extraction in the former group (23/24, 95.8%) was higher than that of the latter group (17/23, 73.9%) (P<0.05), and local mucosal bleeding correlated with the endoscopic operation in the former group was lower than that of the latter group (P<0.05).

Conclusions

The use of a transparent cap could shorten the time of extraction and improve the success rate of extraction through a gastroscope in treating pediatric foreign bodies in the entrance of the esophagus in a waking state. This is an effective and safe treatment approach for pediatric foreign bodies in the entrance of the esophagus.

Cap-Assisted Technique versus Conventional Methods for Esophageal Food Bolus Extraction: A Comparative Study

BACKGROUND/AIMS

Food bolus impaction is the most common form of esophageal foreign body impaction observed in adults. Clinical guidelines recommend using the push technique or retrieval methods in such cases. The push technique can cause injuries in certain clinical situations. Notably, conventional retrieval methods are time and effort consuming. Cap-assisted endoscopic extraction of an impacted food bolus is an easy and effective technique; however, more data are needed for its validation. This study compared the capassisted extraction technique with conventional methods.

METHODS

This prospective observational multicenter study compared the success and en bloc removal rates, total procedure time, and adverse events in both techniques..

RESULTS

The study included 303 patients who underwent food bolus extraction. The push technique was used in 87 patients (28.7%) and a retrieval procedure in 216 patients (71.3%). Cap-assisted extraction was performed in 106 patients and retrieval using conventional methods in 110 patients. The cap-assisted technique was associated with a higher rate of en bloc removal (80.2% vs. 15%, p<0.01), shorter procedure time (6.9±3.5 min vs. 15.7±4.1 min, p<0.001), and fewer adverse events (0/106 vs. 9/110, p<0.001).

CONCLUSION

Cap-assisted extraction showed no adverse events, higher efficacy, and a shorter procedure time compared with conventional retrieval procedures.

Delayed endoscopic removal of sharp foreign body in the esophagus increased clinical complications: An experience from multiple centers in China

Foreign bodies impaction in the esophagus is a common clinical emergency. The aim of this study was to investigate the clinical features of foreign body ingestion, and to analyze the risk factors of complications during the endoscopic procedure.From 18 general hospitals in Zhejiang Province in China, 595 patients who underwent gastroscopic removal of ingested foreign bodies were prospectively recruited. Patient characteristics, clinical features, foreign body features, clinical outcomes, and complications were documented.The most common types of foreign body in the esophagus were sharp objects (75.9%), including fish bones (34.0%), chicken bones (22.1%), and fruit nuclei (17.1%). The remaining types were non-sharp objects (24.1%), including food bolus (14.6%). Most objects were lodged in the proximal esophagus (75.9%). Foreign body-related complications occurred in 63 patients (10.5%), including hemorrhage (5.0%), perforation and infection (5.5%). The complication rate was increased by 4.04- and 8.48- fold when endoscopic retrieval was performed after impacted for over 24 and 48 hours, respectively, after impaction, as compared with within 12 hours. Logistic regression analysis revealed that the patients with sharp objects developed more complications than those with non-sharp ones (odds ratio, 2.85; 95% confidence interval, 1.08-7.50; P = .034). However, complications were unrelated with the location in the esophagus or length of foreign bodies (P > .05).Sharp objects were the most frequently ingested foreign bodies in the esophagus in China. The prevalence of complications was increased in the patients with long foreign body retention time (>24 hours) and sharp objects. Sharp foreign bodies in the esophagus are recommended to be removed within 24 hours.

Esophageal foreign bodies in adults: systematic review of the literature

OBJECTIVE

Esophageal Foreign Body (FB) impaction represents a major challenge for healthcare providers. Aim of this systematic review was to analyse the current literature evidence on prevalence, presentation, treatment, and outcomes of impacted esophageal FB.

MATERIALS AND METHODS

Literature search was conducted between 2000 and 30th June 2018 according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement.

RESULTS

Sixty-one studies matched the inclusion criteria. The total number of included patients was 13,092. The cervical esophagus was the most frequent impaction site (67%) and sharp-pointed objects were the most common FB (38.1%). Retrosternal pain (78%), dysphagia (48%), and odynophagia (43.4%) were the most common symptoms. A flexible or rigid endoscopic approach was adopted in 65.1% and 16.8% of patients, respectively. Overall, 17.8% of patients had a complication related to the impacted esophageal FB or to the endoscopic manoeuvers. A surgical approach was required in 3.4% of patients. The overall mortality was 0.85%.

CONCLUSIONS

Surgery is the upfront treatment in patients with esophageal perforation or endoscopically irretrievable esophageal FB. A minimally invasive approach can be adopted in selected patients. Effective prevention of FB impaction should focus on accurate diagnostic work-up to search for an underlying motility disorder after a first episode of esophageal impaction, even if transient and self-resolving.

Foreign object ingestion and esophageal food impaction: An update and review on endoscopic management

Foreign body ingestion encompasses both foreign object ingestion (FOI) and esophageal food impaction (EFI) and represents a common and clinically significant scenario among patients of all ages. The immediate risk to the patient ranges from negligible to life-threatening, depending on the ingested substance, its location, patient fitness, and time to appropriate therapy. This article reviews the FOI and EFI literature and highlights important considerations and implications for pediatric and adult patients as well as their providers. Where published literature is insufficient to provide evidence-based guidance, expert opinion is included to supplement the content of this comprehensive review.

Retrospective analysis of endoscopic management of foreign bodies in the upper gastrointestinal tract of adults

BACKGROUND

Foreign body impaction in the upper gastrointestinal (UGI) tract is considered an emergency worldwide. This article reports our experience in the endoscopic management of foreign bodies in the UGI tract of adults.

METHODS

A retrospective chart review was conducted on adult patients (aged >18 years) who received endoscopic management of foreign bodies in the UGI tract at Shuang Ho Hospital between November 2008 and November 2016.

RESULTS

A total of 280 patients (male/female: 107/178; mean age: 56 years) were included. Fish bones were the most common ingested foreign bodies (n = 162; 56.8%), and the esophagus was the most common lodgment site (n = 222; 77.9%). The presence of symptoms indicated that the ingested foreign bodies were lodged in the hypopharynx or esophagus rather than in the stomach or duodenum (p < 0.01). The detection rate of ingested foreign bodies in the UGI tract through plain radiography was 53% (122/230). The average "door-to-scope" was 5.9 hours, and 99.2% of the patients received endoscopic management of the ingested foreign bodies within 24 hours. The complication rate was relatively low (n = 14; 4.9%). No patient received surgical intervention or died of endoscopic management.

CONCLUSION

Endoscopic management is a safe and highly effective procedure for extracting ingested foreign bodies. Rapid endoscopic intervention should be provided to reduce the risk of complications.

Diabetes is an independent risk factor for delayed perforation after foreign bodies impacted in esophagus in adults

Background

Perforation is the most serious complication of esophageal foreign bodies. Studies examining the association between diabetes and esophageal foreign body-induced perforation are largely non-existent.

Objectives

The purpose of this study was to identify the risk factors for esophageal foreign body-induced perforation.

Methods

A retrospective chart review of patients with esophageal foreign bodies between January 2012-January 2017 was performed at the Chinese People's Liberation Army General Hospital. The patients were divided into two groups: those complicated with perforation and those without perforation. Date on patient demographics, symptoms, foreign bodies, and diabetes were collected and analyzed. Study-specific odds ratio and 95% confidence intervals (CI) were estimated using multivariable logistic regression models.

Results

Of 294 patients with esophageal foreign bodies (41.84% male, mean age, 56.73 years), 33 (11.22%) complicated by perforation. Diabetes (odds ratio = 6.00; 95% confidence interval = 1.72-20.23), duration (>24 h) of foreign bodies retention (odds ratio = 4.25; 95% confidence interval = 1.71-10.86), and preoperative fever (odds ratio = 8.19; 95% confidence interval = 3.17-21.74) were strongly associated with an increased risk of perforation, whereas the sensation of a foreign body (odds ratio = 0.32; 95% confidence interval = 0.09-0.92) was a protective factor of perforation. Glucose level was not observed to have an association among patients with or without perforation.

Conclusions

Diabetes and duration of foreign body retention increase risk for esophageal foreign bodies complicated by perforation, and cases with elevated armpit temperature may represented a more likely perforation compared with those without fever.

Effectiveness of a cap-assisted device in the endoscopic removal of food bolus obstruction from the esophagus

BACKGROUND AND AIM

The use of a transparent cap has been found to be effective for retrieval of an esophageal foreign body. However, data on the use of a cap in food bolus obstruction (FBO) are limited. This study aims to assess the effectiveness of a cap-assisted technique compared with conventional techniques in removal of FBO.

METHODS

All patients who underwent an endoscopy for boneless FBO between 2011 and 2016 were prospectively recruited. The measured outcomes were procedure time, success rate of food bolus (FB) extraction, rate of en bloc removal, procedure-related adverse events, and length of hospital stay (LOS) between the 2 groups.

RESULTS

Of the 315 patients who had an endoscopy for FBO, 48 (15.2%) had spontaneous passage of FB and 267 (84.8%) had impacted FB. Sixty-eight (25%) patients had the "push" maneuver, and 199 (75%) patients had the "pull" maneuver to remove FB. Of those who had the "pull" maneuver, a cap was used for 93 and conventional device(s) for 106. The use of a cap was associated with a shorter procedural time (34.3 ± 8.0 minutes versus 43.3 ± 22.6 minutes, P = .003), a higher rate of en bloc removal (87.3% versus 22.8%, P < .001), a lower rate of adverse events (0/93 versus 7/106, P = .01), and a shorter LOS (1.0 ± 0.6 days versus 1.6 ± 1.4 days, P = .0017).

CONCLUSION

The cap-assisted technique has been found to be effective and safe in removal of esophageal FBO. This technique was associated with a shorter procedural time and a reduced LOS compared with conventional techniques. However, these findings require further validation in a randomized control study.

Foreign Body Ingestion in Children

Foreign body (FB) ingestion in children is common and most children are observed to be between 6 months and 3 years of age. Although most FBs in the gastrointestinal tract pass spontaneously without complications, endoscopic or surgical removal may be required in a few children. Thus, FB ingestion presents a significant clinical difficulty in pediatric gastroenterological practice. Parameters that need to be considered regarding the timing of endoscopic removal of ingested FBs in children are the children's age or body weight, the clinical presentation, time lapse since ingestion, time of last meal, type as well as size and shape of the FB, and its current location in the gastrointestinal tract. Esophageal button batteries require emergency removal regardless of the presence of symptoms because they can cause serious complications. Coins, magnets, or sharp FBs in the esophagus should be removed within 2 hours in symptomatic and within 24 hours in asymptomatic children. Among those presenting with a single or multiple magnets and a metallic FB that have advanced beyond the stomach, symptomatic children need a consultation with a pediatric surgeon for surgery, and asymptomatic children may be followed with serial X-rays to assess progression. Sharp or pointed, and long or large and wide FBs located in the esophagus or stomach require endoscopic removal.

Analysis of the management and risk factors for complications of esophageal foreign body impaction of jujube pits in adults

Introduction

Foreign body impaction is a common emergency in the field of otolaryngology. The prevalence of a jujube pit as an esophageal foreign body has increased in the Jiaodong Peninsula. However, reports on this are scarce.

Aim

To investigate the methods for diagnosing and treating esophageal foreign body impaction of a jujube pit and to determine the risk factors for complications.

Material and methods

We conducted a retrospective review of the medical records of patients who were diagnosed with esophageal impaction of a jujube pit. Demographic, clinical, radiological, and endoscopic data were collected and analyzed.

Results

Neither plain radiography nor esophagogram provided enough information on the surrounding issues and complications. The rate of secondary radiological examination was 51.61% for the patients who did not undergo prior computed tomography. The success rate of rigid esophagoscopy was 95.45%; 18 of these patients (27.27%) had previously undergone flexible esophagoscopy without foreign body removal. Logistic regression showed that the time from ingestion to presentation and the jujube pit size were independent risk factors for complications.

Conclusions

Computed tomography without contrast material is the preferred diagnostic method for adults with esophageal jujube pit impaction, and rigid esophagoscopy can be used for therapy even though the first flexible esophagoscopy failed. Large diameter of the jujube pit constituting the esophageal foreign body (≥ 25 mm) and long duration between pit ingestion and presentation (> 12 h) were associated with increased complications in the patients in this study.

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.

Endoscopic management of foreign bodies in the upper gastrointestinal tract: a retrospective study of 1294 cases

OBJECTIVE

To report our endoscopic outcomes and explore the effects of duration of impaction and anesthetic methods on the endoscopic removal of foreign bodies in the upper gastrointestinal tract.

METHODS

All consecutive patients with suspected foreign body (FB) ingestion between January 2013 and June 2016 were enrolled. Demographic, clinical and endoscopic data were collected and analyzed.

RESULTS

A total of 1294 patients aged seven months to 94 years were enrolled. Odynophagia (415 cases, 32.1%), FB sensation (340 cases, 26.3%) and sore throat (267 cases, 20.1%) were the most frequent complaints. The duration of FB impaction ranged from 4 h to over two years. Anatomically, foreign bodies were most commonly located in the esophagus (n = 1025, 86.9%). Bony foreign bodies comprised the majority of identified foreign bodies. The most common underlying pathology was esophageal stricture (38 cases, 53.5%). Nearly half of the patients (49.9%) developed complications. As the duration of impaction increased, the success rate by endoscopy decreased (p < .001), and the complication rate increased (p < .001). Endoscopic management under general anesthesia didn't improve the success rate or lower the complication rate compared with topical pharyngeal anesthesia (p = .793 and p = .085). Age ≥60, duration of impaction longer than one day, impaction in the esophagus, and sharp foreign bodies were identified as risk factors for complications.

CONCLUSIONS

Delayed flexible endoscopy in patients, especially elderly patients, with sharp FB impactions in the esophagus results in worse endoscopic outcomes. Endoscopic management under general anesthesia did not improve the therapeutic results compared with topical pharyngeal anesthesia.
