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?p?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.     

Cervical Osteophytes Increase the Risk for Foreign Body Impaction: A 171-Patient Case–Control Study

The aim of this study is to define the relationship between anatomical and pathological cervical structures and the impaction of ingested foreign bodies (FBs). The effects of such structures on deglutition have been previously discussed, however their contribution to FB impaction has not yet been examined. This was a retrospective case–control study of 171 patients who underwent computed tomography (CT) scans over the period 2008–2014: 57 patients with an esophageal or hypopharyngeal FB; the other 114 comprised the control group, selected using the ‘neighbor control’ method. CT scans were reviewed for measurements of cervical structures. The mean age was 63 ± 13 years and 55 ± 17 years in the case and control groups, respectively (p-value = 0.003). Age was the only demographic or clinical characteristic which demonstrated a significant difference. Overall, 24 patients had cervical osteophytes: 28 %(16) with an impacted FB, compared with 7 %(8) from the control group (p-value < 0.001). Of the patients with osteophytes and impacted FBs, 62.5 % had the FB lodged at a vertebral level corresponding to their osteophytes, while another 18.75 % had the FB within three vertebral levels above the osteophytes. Stepwise logistic regression revealed that osteophytes were a significant factor, independent of older age (p-value = 0.004). Adjusted odds ratio for FB impaction in the presence of osteophytes was 4.04. Ventral cervical osteophytes increase the risk for FB impaction in the upper digestive tract. This risk is independent of older age. These findings can be of value in preventive medicine, and emphasize the importance of looking for spinal changes in patients with recurrent FB impaction.     

What predictive parameters best indicate the need for emergent gastrointestinal endoscopy after foreign body ingestion?

Our aim was to determine what parameters may be used to indicate an emergent endoscopy after foreign body (FB) ingestion and to ascertain how often FBs are found endoscopically. Demographic data, gastroesophageal antecedents, clinical and endoscopic data, and complications were obtained. We examined 122 patients endoscopically. The onset of symptoms was immediate after FB ingestion in 93% of patients. Dysphagia was the most frequent symptom (66%), with the pharynx the most frequent location of impaction (71%). Endoscopy confirmed the presence of FBs in 52% of patients. Extraction was performed in 78%. The immediate onset of symptoms, dysphagia, and the absence of pharynx localization of impaction were predictive indicators of a positive FB finding (p < 0.05), with diagnostic sensitivity of 86% and specificity of 63%. Upper endoscopy should be performed in all patients with FB ingestion, even though no FB was found in 48%.     

Risk factors for complications associated with upper gastrointestinal foreign bodies

AIM: To investigate predictive risk factors associated with complications in the endoscopic removal of foreign bodies from the upper gastrointestinal tract.METHODS: We retrospectively reviewed the medical records of 194 patients with a diagnosis of foreign body impaction in the upper gastrointestinal tract,confirmed by endoscopy,at two university hospital in South Korea.Patient demographic data,including age,gender,intention to ingestion,symptoms at admission,and comorbidities,were collected.Clinical features of the foreign bodies,such as type,size,sharpness of edges,number,and location,were analyzed.Endoscopic data those were analyzed included duration of foreign body impaction,duration of endoscopic performance,endoscopic device,days of hospitalization,complication rate,30-d mortality rate,and the number of operationsrelated to foreign body removal.RESULTS: The types of upper gastrointestinal foreign bodies included fish bones,drugs,shells,meat,metal,and animal bones.The locations of impacted foreign bodies were the upper esophagus(57.2%),mid esophagus(28.4%),stomach(10.8%),and lower esophagus(3.6%).The median size of the foreign bodies was 26.2 ± 16.7 mm.Among 194 patients,endoscopic removal was achieved in 189,and complications developed in 51 patients(26.9%).Significant complications associated with foreign body impaction and removal included deep lacerations with minor bleeding(n = 31,16%),ulcer(n = 11,5.7%),perforation(n = 3,1.5%),and abscess(n = 1,0.5%).Four patients underwent operations because of incomplete endoscopic foreign body extraction.In multivariate analyses,risk factors for endoscopic complications and failure were sharpness(HR = 2.48,95%CI: 1.07-5.72; P = 0.034) and a greater than 12-h duration of impaction(HR = 2.42,95%CI: 1.12-5.25,P = 0.025).CONCLUSION: In cases of longer than 12 h since foreign body ingestion or sharp-pointed objects,rapid endoscopic intervention should be provided in patients with ingested foreign bodies.     

Diagnosis and endoscopic management of upper gastrointestinal foreign bodies

IntroductionThe objective is to evaluate the diagnosis of foreign body (FB) ingestion and report on the endoscopic management in Taiwan.MethodsThis retrospective study enrolled 159 adult patients with confirmed diagnosis of upper gastrointestinal FBs who received endoscopic management in the emergency department.ResultsThe patients’ mean age was 57.0 ± 19.2 years, and 66 (37.7%) of the patients were 65 years or older. Majority had a clear history and symptoms of FB ingestion. However, 9 (5.7%) initially ignored the accidental swallowing of FBs and were diagnosed late. The mean time spent for diagnosis was 1.8 days in those with uncertain history. Only 47.1% of those with radiographic studies had positive findings. Fish bones, press-through package and dentures were the most common culprits in this population of Asian elderly. Majority of FBs were located in the esophagus, especially in the upper third. Endoscopic FB extraction was successful in 96.9% of cases, while surgery was required in only 5 patients. The complication rate was 6.9%, including mucosal laceration (n = 10) and suspected perforation (n = 1), all of which were successfully managed conservatively. There was no death due to FB ingestion or endoscopy.ConclusionsIn FB ingestion, history usually points toward the diagnosis. Patients with an uncertain history are usually diagnosed late, and plain radiography cannot reliably predict the presence of FB. Endoscopic management is safe and effective for FBs.

Cervical cellulitis and mediastinitis following esophageal perforation：A case report

Chicken bone is one of the most frequent foreign bodies （FB） associated with upper esophageal perforation. Upper digestive tract penetrating FB may lead to life threatening complications and requires prompt management. We present the case of a 52-year-old man who sustained an upper esophageal perforation associated with cervical cellulitis and mediastinitis. Following CT-scan evidence of FB penetrating the esophagus, the impacted FB was successfully extracted under rigid esophagoscopy. Direct suture was required to close the esophageal perforation. Cervical and mediastinal drainage were made immediately. Nasogastric tube decompression, broad-spectrum intravenous antibiotics, and parenteral hyperalimentation were administered for 10 d postoperatively. An esophagogram at d 10 revealed no leak at the repair site, and oral alimentation was successfully reinstituted. Conclusion： Rigid endoscope management of FB esophageal penetration is a simple, safe and effective procedure. Primary esophageal repair with drainage of all affected compartments are necessary to avoid life-threatening complications.     

Foreign bodies in the tracheobronchial tree

Between 1972 and 1984, we treated 66 patients with foreign bodies (FBs) in the tracheobronhial tree. Twenty-six patients (39.4 percent) were between one and two years old; 52 (78.8 percent) were under age ten. Forty-four FBs (67 percent) were fruit and vegetable seeds and nuts. Soft organic material (meat, cucumber peels) was found in four patients, chicken bones in six, pins and needles in six, other nonorganic materials (toys, stone, broken thermometer) in six. In 55 patients, the FB was removed at bronchoscopy; three patients coughed up the FB shortly after bronchoscopy. Eight patients were operated on because the impacted FB could not be removed at repeat bronchoscopy trials. In this group, the FB was removed through a bronchotomy in two patients, but in six, pulmonary resection was necessary because of severe bronchiectasis (FBs had been impacted from ten months to 12 years). Stiff bronchoscope was used in all patients. In several cases, the flexible bronchoscope was used initially but proved inadequate. There were three complications, two related to hypoxia, but no deaths. Infants and little children should be prevented from reaching peanuts and seeds. When presence of a FB is suspected, and in children with unresolving pneumonic process, early bronchoscopy is mandatory. Expert anesthesia is essential, and hypoxia must be avoided.     

Endoscopic removal of accidental aspirated and ingested dental foreign bodies: A cross-sectional study

The incidence of accidental ingestion and aspiration of foreign body (FB) is likely to occur. Many FBs are discharged spontaneously, but many dental FBs are often sharp and may remain in the pharynx, esophagus, and stomach, causing serious complications such as hemorrhage, asphyxia, perforation of the digestive tract, mediastinal emphysema, peritonitis, and ileus. We aimed to examine which type of dental foreign bodies can be removed by endoscope.In this study, we enrolled 32 patients who were evaluated at the Emergency and Critical Center between January 2014 and December 2019 and who accidentally ingested or aspirated dental FBs. Medical records were reviewed to determine the patients’ sex, age, medical history, time from accidental ingestion of a FB to consultation, cause, location, occurrence status, nature of the FB, location of retained FB, treatment, complications, and outcome.We enrolled 32 patients (14 men, 18 women), with a mean age of 74.5 ± 12.8 years. Accidental ingestion at treatment was common. The most frequent site where the FB was retained was upper gastrointestinal tract (26 cases, 81.3%). In this study, endoscopic removal was indicated for dentures under the size of 43.3 mm, for dental FB (except dentures) more than 13.6 mm. In dentures, between the number of missing teeth, clasp, type, and endoscopic removal was not statistically significant.Dentures under the size of 43.3 mm was likely to be removed by endoscope. Dental FB (except dentures) more than the size of 13.6 mm was likely to be removed by endoscope. There were no indications for endoscopic removal except for size.     

Management of esophageal foreign bodies: experience of 90 cases

Background

In Japan, there have been few recent reports of large-scale studies on the characteristics and optimal treatment of esophageal foreign bodies.

Methods

We analyzed data on 90 patients diagnosed as having esophageal foreign bodies treated between April 2002 and August 2007.

Results

In children younger than 15 years (n = 13), the types of foreign bodies included coins (n = 9), food (n = 1), and other objects (n = 3), 12 of which were successfully removed without endoscopic procedures; in the remaining 1 case, the object advanced to the lower digestive tract spontaneously. In adults aged 15 years or older (n = 77), the types of foreign bodies included food-bolus impaction (n = 26), press-through packages (n = 18), fish bones (n = 14), dental prostheses (n = 13), and other objects (n = 6). The foreign bodies had advanced to the lower digestive tract in 4 patients at the time of flexible endoscopy performed under topical pharyngeal anesthesia. In 6 of the remaining 73 patients, the first endoscopic extraction was unsuccessful, and 5 of these cases involved dental prostheses. The mean maximal size of the dental prosthesis was significantly greater in patients in whom removal was unsuccessful than in those in which it was successful (5.8 versus 1.6 cm, respectively; P < 0.05). The procedures employed following unsuccessful endoscopy included thoracotomy (n = 1), laparotomy (n = 1), removal by forceps under direct vision (n = 1), and rigid (n = 1), and flexible endoscopy (n = 2) under general anesthesia.

Conclusions

The majority of esophageal foreign bodies were successfully removed nonendoscopically in pediatric patients and endoscopically in adult patients. Endoscopic removal under topical pharyngeal anesthesia may not be indicated for patients who have swallowed large dental prostheses.     

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.

A sewing needle in the liver in children: A case report and literature review

Rationale:In clinical practice, foreign bodies (FBs) in the digestive tract are more common in children, but intrahepatic FBs are rare, especially those that can cause infection, bleeding, bile leakage, and other complications. However, there is no consensus on its diagnosis and treatment due to the lack of large-scale cohort studies.Patient concerns:Case 1 is a 4-years 8-months-old girl, who at the age of 10 months, showed an X-ray finding of a striped FB in her liver, with no symptoms. However, the patient’s parents refused surgery. After nearly 4 years of active surveillance, the patient visited our hospital for surgery. Case 2, a 2-year-old male, reported a sewing needle that completely pierced into the right upper abdomen due to an accidental fall that took place half-a-day before admission. He only had right upper abdominal pain. CT showed a striped FB in the liver.Diagnosis:FB in the liver (sewing needle).Interventions:Both the patients were injected with human tetanus immunoglobulin and underwent surgical removal.Outcomes:Both patients recovered smoothly and had no complications during follow-up.Lessons:Active surveillance might be considered for cases with no symptoms or complications and no displacement of the FB, but surgery should be the first choice. If the patient’s condition is complicated, it is recommended to use ultrasound or X-ray to help decision-making during the operation. Additionally, tetanus, child safety, and family education are important supportive measures.     

Management of ingested foreign bodies in upper gastrointestinal tract: report on 170 patients.

BACKGROUND: Ingestion of foreign bodies (FB) is commonly encountered in gastrointestinal practice. METHODS: Retrospective analysis of data on endoscopic removal of FB in 170 patients (124 children) who were managed at a tertiary referral center over a six-year period. OUTCOME: Coins were the most common FB removed (n=134). Dentures (12), food boluses (19), sharp objects such as needles and pins (7), and certain unusual FB (12) made up the remainder. Esophagus was the most common site of FB lodgement (56%). Most patients with esophageal FB complained of FB sensation, dysphagia, odynophagia or chest pain. Gastric and duodenal FB produced no symptoms. FB could be successfully removed endoscopically in 166 patients (97.6%) without morbidity or mortality. Four patients required surgical removal of FB. Certain Innovative methods like loop basket, electrocautery and suction retrieval were used to remove some FB. CONCLUSION: Endoscopic removal of FB in the esophagus and stomach is safe but often requires the use of innovative techniques and accessories.     

Endoscopic management of suspected esophageal foreign body in adults

Foreign bodies should not be allowed to remain in the esophagus beyond 24 hours after presentation. However, some patients with esophageal foreign body ingestion do not come to the hospital immediately and may delay medical intervention from the time of ingestion. The aim of this study was to investigate the outcomes of adults with suspected esophageal foreign body ingestion according to the time of ingestion and types of foreign bodies. A total of 326 adult patients (151 men and 175 women) were analyzed, and divided into two groups according to the time period: within or beyond 24 hours from ingestion to endoscopic intervention. A total of 172 patients (52.7%) were found to have ingested foreign bodies; 73.5% were removed smoothly, 10.3% were treated by push technique and 16.0% with failed retrieval received alternative treatments. A higher proportion of patients in the beyond‐24 hours group suffered from odynophagia (25.9 vs. 12.9%, P < 0.05). Negative identification of esophageal foreign bodies was more frequent in the beyond‐24 hours group (67 vs. 40.2%, P < 0.05), but these patients showed higher proportions of esophageal ulcers (21.1 vs. 7.2%, P < 0.05). The beyond‐24 hours group also showed a significantly higher rate of foreign bodies in the lower esophagus (40.0 vs. 15.3%, P < 0.05). Patients with esophageal food bolus impaction had significant delayed endoscopic intervention, longer therapeutic endoscopic time, higher proportions of esophageal cancer, stricture and fewer complications. Endoscopic intervention within 24 hours from the time of ingestion should be considered early in adults, because delaying intervention may produce more symptomatic esophageal ulcerations with odynophagia.     

Airway foreign bodies: what's new?

Tracheobronchial foreign body (FB) aspiration is a common problem in children and adults. The medical history is the single most predictive factor in the clinical suspicion of FB aspiration. The "penetration syndrome" defined by the sudden onset of choking and coughing with or without vomiting should prompt concerns for FB aspiration. Findings on radiographic imaging include visualization of a radiopaque FB, atelectasis, postobstructive changes, mediastinal shift, and pneumomediastinum. In the presence of a high clinical suspicion even with normal imaging studies, bronchoscopy should be performed for a thorough evaluation of the airways. Bronchoscopic extraction of airway FBs can be safely accomplished with both the rigid as well as the flexible bronchoscope in adults and children. Rigid bronchoscopy allows for control of the airway and provides excellent visualization with a variety of ancillary instruments available. Increasingly, both the adult and pediatric flexible bronchoscopes have been used successfully in the extraction of airway FBs utilizing urologic or bronchoscopic instruments. Airway control can be achieved with an endotracheal tube or a laryngeal mask airway. A delay in diagnosis increases morbidity including cough, wheeze, edema, and granulation tissue formation. Bronchoscopic evaluation and removal should be performed as soon as the diagnosis is suspected.     

Foreign bodies in the esophagus. A study of causative factors

Two hundred and twenty-nine patients were studied in an attempt to determine the main causative factors behind their having a residual foreign body in the esophagus. Strictures were present in 13%. Fifty-two percent of the patients with stricture had been hospitalized more than once for treatment of foreign body impaction; this was the case in only 8.5% of the rest of the patients (p<0.001). More than half of the patients aged 15 years or younger had a foreign body in the hypopharynx. This location was extremely uncommon in adults (p<0.001). The hypothesis of spasm distal to an esophageal foreign body as the cause for obstruction in patients without esophageal stricture was supported by the following findings: spontaneous disimpaction occurred in more than one-third of the patients and became more frequent as time progressed; 63% of 16 patients given spasmolytic drugs experienced spontaneous disimpaction of the foreign body; half of the patients had the foreign body in the proximal esophagus distal to the narrower passage of the upper esophageal sphincter; foreign body impaction in the esophagus turned out to be a once-only event in 86% of the patients; and 21% of the patients had a disorder of the central nervous system and had been hospitalized significantly more often because of food impaction than the other patients. The findings indicate that adults with a history of impaction of foodstuff lacking sharp bones and who do not have stricture suffer food impaction because of spasm of the esophageal smooth muscle, and can be treated accordingly.     

Extraction des corps étrangers du tractus digestif haut par voie endoscopique : expérience d’un service de gastro-entérologie. À propos de 92 cas

Background

Foreign body ingestion is frequent in children and in specific high risk groups of adults such as those with underlying esophageal disease, prisoners, the mentally retarded and those with psychiatric illness.

Aims

To report the management and outcomes of patients with suspected ingestion of foreign bodies treated by endoscopic extraction.

Methods

Between 1985 and 2007 a total of 72 patients with 102 suspected foreign bodies underwent endoscopic procedures.

Results

A total of 92 foreign bodies were found in 62 patients. In the pediatric population, coins were the most frequent foreign body ingested (57 %) and in prisoners, metal objects were the most frequent (82 %). Bolus food impaction was located in the esophagus, coins and metallic foreign bodies in the stomach. Endoscopic extraction was possible in 92 % of cases without any complications.

Conclusion

Endoscopic removal of foreign bodies located in the upper gastro-intestinal tract is safe and successful.     

Lateral spine dual-energy X-ray absorptiometry bone mineral measurement with fan-beam design: effect of osteophytic calcifications on lateral and anteroposterior spine BMD

Recently, fan beam (FB) designs have been made available by several manufacturers (Aloka, Hologic Lunar and Sophar) to measure lumbar spine bone mineral area density (BMD) in both an anteroposterior (AP) and a lateral projection. The present study was performed to evaluate some characteristics of a new dual energy X-ray absorptiometry (DXA) system for supine lateral scans in normals and to study possible advantages for patients with ostcophytic calcifications (OC). The precision errors of in vitro and in vivo measurements were estimated by an anthropomorphic phantom and in healthy volunteers. To study the effect of osteoarthritic changes on AP and lateral DXA measurements, BMC (bone mineral content) and BMD were measured in age-matched women (n=150) with and without OC. Precision errors for lateral BMD in vitro over 1 and 6 months were 0.58/0.67% (slow/fast scan modes) and 0.67/0.77% (slow/fast scan modes), respectively. The short- and mid-term reproducibility of BMD values were 2% and 3.5%, respectively, using the compare function (3.5% and 7.5%, respectively, without the compare facility). The analysis of women with and without OC (n=150) demonstrated higher mean values for AP BMD (0.892±0.145 g/cm²) in patients with OC (n=75) than in normals (0.836±0.135 g/cm², n=75, difference 6.3%). For lateral scans, BMD differed to a minor degree (3.1%) in patients with OC (0,629±0.133 g/cm²) compared with normals (0.610±0.117 g/cm²). Corresponding results were obtained in fast FB mode. Furthermore, we found significant (P<0.0001) correlations between BMD in lateral and AP scans in patients without OC (r=0.63) and in patients with OC (r=0.75). Although the FB design facilitated fast AP and lateral scans, the higher precision errors of lateral scans could limit its application in longitudinal studies. The use of compare function should be recommended. However, BMD of lateral scans was less influenced by OC.     

Factores predictores de esofagitis eosinofílica en impactación esofágica por bolo alimenticio

BackgroundFood 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.AimTo detect eosinophilic esophagitis predictive factors in patients with esophageal impaction due to food bolus.MethodsPatients 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.ResultsOf 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).ConclusionsAge and a history of impaction predict the presence of eosinophilic esophagitis in patients with food bolus impaction.
