Flexible bronchoscopy for foreign body aspiration in children:A single-centre experience

BACKGROUND The technological evolution of bronchoscopy has led to the widespread adoption of flexible techniques and their use for both diagnostic and therapeutic purposes.Currently,there is an active debate regarding the comparative efficacy and safety of rigid vs flexible bronchoscopy in the treatment of foreign body aspiration.AIM To evaluate our experience with tracheobronchial foreign body extraction using flexible bronchoscopy and provide a literature overview.METHODS This was a single-centre retrospective study.Twenty-four patients were enrolled between January 2017 and January 2023.Medical records of patients aged below 18 years who were admitted to authors’affiliated institution with a suspected diagnosis of foreign body aspiration were collected from hospital’s database to Microsoft Excel 2019.Data were analysed using MedCalc Statistical Software.RESULTS Patient ages varied from 9 months to 11 years.The median age was 23.5 months,95%confidence interval(CI)19.49-44.77.We observed age clustering in children with foreign body aspiration at our institution with three age subgroups:(1)0-25 months;(2)40-60 months;and(3)120-140 months.We expectancy of an organic tracheobronchial foreign body was significantly higher in 0-25 months subgroup than that in older ones when subgroups 40-60 and 120-140 months were combined together(odds ratio=10.0,95%CI:1.44-29.26,P=0.0197).Successful foreign body extraction was performed in all cases.Conversion to a rigid bronchoscope was not required in any of the cases.No major complications(massive bleeding,tracheobronchial tree perforation,or asphyxia)were observed.CONCLUSION Flexible bronchoscopy is an effective and safe method for tracheobronchial foreign body extraction in children.

Colonoscopy-assisted removal of an impaction foreign body at the rectosigmoid junction: A case report

BACKGROUND When an anorectal foreign body is found,its composition and shape should be evaluated,and a timely and effective treatment plan should be developed based on the patient's symptoms to avoid serious complications such as intestinal perforation caused by displacement of the foreign body.CASE SUMMARY A 54-year-old male was admitted to our outpatient clinic on June 3,2023,due to a rectal foreign body that had been embedded for more than 24 h.The patient reported using a glass electrode tube to assist in the recovery of prolapsed hemorrhoids,however,the electrode tube was inadvertently inserted into the anus and could not be removed by the patient.During hospitalization,the patient underwent surgery,and the foreign body was dragged into the rectum with the aid of colonoscopy.The anus was dilated with a comb-type pulling hook and an anal fistula pulling hook to widen the anus and remove the foreign body,and the local anal symptoms were then relieved with topical drugs.The patient was allowed to eat and drink,and an entire abdominal Computed tomography(CT)and colonoscopy were reviewed 3 d after surgery.CT revealed no foreign body residue and colonoscopy showed no metal or other residues in the colon and rectum,and no apparent intestinal tract damage.CONCLUSION The timeliness and rationality of the surgical and therapeutic options for this patient were based on a literature review of the clinical signs and conceivable conditions in such cases.The type,material and the potential risks of rectal foreign bodies should be considered.

Combined laparoscopic and endoscopic method for foreign body removal from descending colon: A case report

BACKGROUND The majority of published reports on foreign bodies(FBs)involve the rectum and applied a transanal retrieval.Usually,patients with FB above the rectum are subjected to laparotomy for removal.Here,we illustrate the case of a man with an FB that had migrated into the descending colon,and its successful removal via a laparoscopic approach.CASE SUMMARY A 43-year-old man,who had the habit of FB insertion into his anus to aid defe-cation,presented upon experience of such an FB slipping through and migrating upward to the distal colon.Plain abdominal radiograph revealed a bottle-shaped FB,positioned in the left iliac fossa region.The FB was successfully removed via a laparoscopic-assisted procedure in which we combined diagnostic laparoscopic and endoscopic techniques during surgery.The patient was monitored for 2 d postoperatively and subsequently discharged home.CONCLUSION A minimally invasive approach should be adopted to aid extraction of colorectal FB as it is effective and safe.

Degradation of differently processed Mg-based implants leads to distinct foreign body reactions(FBRs)through dissimilar signaling pathways

Mg alloys have mechanical properties compatible with human bones.However,their rapid degradation and associated foreign body reactions in vivo significantly limit their application for human implants.In this study,three differently processed Mg alloys,pure Mg(PM),cold extruded Mg alloy AZ31(CE AZ31),and fully annealed AZ31 Mg alloy(FA AZ31)were comparatively investigated for their potential as implants using a rat model.All three implanted Mg alloys do not show any impact on hepato-and renal function,nor any signs of observable changes to vital organs.Proteomics analysis of tissues directly contacting the implants 2.5 months post implantation revealed that FA AZ31 activates very few inflammation and immune associated signaling pathways;while the CE AZ31 and PM produce more significant inflammatory responses as confirmed by cytokine array analyses.Further,FA AZ31 activated pathways for cell organization and development that may improve the recovery of injured tissues.Structurally,EBSD analysis reveals that the FA AZ31 alloy has a higher ratio of first-order pyramidal orientated(10–11){10–1–2}grain texture with a value of 0.25,while PM and CE AZ31 alloys have lower ratios of first-order pyramidal orientated texture with the values of 0.16 and 0.17,respectively.This is associated with recovery and recrystallisation during annealing which promotes grain texture which exhibits enhanced degradation behaviours and induces a more limited immune response in vivo.In conclusion,the FA AZ31 demonstrated better biocompatibility and corrosion resistance and is a promising candidate for metal-based degradable implants which warrants further investigation.

Removal of a pulmonary artery foreign body during pulse ablation in a patient with atrial fibrillation:A case report

BACKGROUND Foreign bodies in the pulmonary circulation have been documented in the literature and are typically caused by interventional procedures.However,reports of pulmonary artery foreign bodies during femoral vein puncture are rare,and there is no description of this complication from the guidewire surface flows into the pulmonary artery during a pulse ablation in a patient with atrial fibrillation.CASE SUMMARY We described a case in which a linear foreign body suddenly appeared on fluoroscopy image during pulsed ablation of atrial fibrillation.Multiposition angiography showed that the foreign body was currently lodged in the pulmonary artery but was hemodynamically stable.We then chose to use an interventional approach to remove the foreign body from the pulmonary artery.This foreign body was subsequently confirmed to be from the hydrophilic coating of the guidewire surface.This may be related to the difficulties encountered during the puncture of the femoral vein.This is a rare and serious complication of femoral vein puncture.Therefore,we reported this case in order to avoid a similar situation.CONCLUSION Mismatches between interventional devices from different manufacturers used for femoral venipuncture may result in pulmonary artery foreign bodies.

Fishbone-Type Pharyngeal Foreign Body with Cutaneous Migration in the ENT Department of the Mamou Regional Hospital: A Case Report

We report a case of pharyngeal foreign body with cutaneous migration in the form of a fishbone in a 24-year-old rural resident, presented with odynophagia, dysphagia, pain and left antero-latero-cervical swelling fistulated to the skin following ingestion of a fishbone during a meal that had been evolving for 2 weeks. Vital parameters were normal, with an unremarkable psychological examination. Clinical examination revealed a left antero-latero-cervical swelling that was painful to palpation, fistulous to the skin and draining frank pus, revealing a sharp fishbone. A standard X-ray showed that the foreign body had exited the pharynx and was located in the soft tissues of the lower neck. An exploratory cervicotomy was performed, allowing extraction of a serrated fishbone. The post-operative course was favorable.

A case of tiny foreign body hidden in the neck for 27 years

Neck trauma has the characteristics of diversity,complexity,and danger.Mild injuries generally require debridement and suturing or symptomatic treatment.In severe cases,acute laryngeal obstruction,subcutaneous emphysema,severe deformation and collapse of laryngeal and tracheal cartilage,or damage to adjacent organs may occur.If not diagnosed in a timely manner or mishandled,it can endanger the patient’s life or leave sequelae.If foreign body residue is caused by head and neck trauma,a reasonable judgment should be made based on the patient’s condition and corresponding measures should be taken.Accurate localization of foreign bodies before and during surgery,as well as appropriate surgical methods,are key to ensuring successful treatment.This article reports a case of a small foreign body in the neck admitted to Xianning Central Hospital at the end of January 2023.

Removal of intraocular foreign body in anterior chamber angle with prism contact lens and 23-gauge foreign body forceps

AIM：To introduce a novel approach in removal of anterior chamber angle foreign body（ACFB） using a prism contact lens and 23-gauge foreign body forceps.METHODS：Data of 42 eyes of 42 patients who had undergone removal of ACFB using a prism contact lens and 23-gauge foreign body forceps from January 2008 to October 2013 were collected and analyzed. Twenty eyes in group A received the conventional approach by using toothed forceps through corneal limbus incision, and 22 eyes in group B underwent the novel method through the opposite corneal limbus incision. RESULTS：The success rate of ACFB once removal was 75%（15/20） in group A, and 100%（22/22） in group B. The average operation time of group A was significantly longer compared with group B（34.9±9.88 min vs 22.13±8.85min; P〈0.05）. The average size of corneal limbus incision in group A was significantly larger than that of group B（4.85±1.89 mm vs 3.95±1.17 mm; P〈0.05）. The corneal limbus incision suturing were conducted in all eyes in group A, and only 5 eyes in group B. CONCLUSION：Removal of ACFB using a prism contact lens and 23-gauge foreign body forceps is a safer, more effective, and convenient technique compared with the conventional approach.

Delayed presentation of intracameral graphite foreign body in a child: school trauma

We report a case of large graphite foreign body(FB) in the anterior chamber of eye of a 4-yearold child,incurred during unsupervised play.Despite delayed presentation,the eye had few signs of resolved inflammation which allowed safe extraction of the FB bimanually through limbus.School play,especially in young children,should be under supervision and free of sharp objects.Graphite is inert while inside the eye,and even large pieces can be well tolerated for long time in absence of infection.

Advantage of Computed Tomography (CT) Virtual Bronchoscopy in the Evaluation of Children with Suspected Foreign Body Airway

Background & Objectives: Foreign body aspiration (FBA) into the tracheo bronchial tree is a frequent and serious cause of respiratory distress and visit to the pediatrics emergency, principally in patients under 3 years of age. Most foreign bodies are not radio opaque and approximately one third of the children admitted will show normal chest X-ray. Virtual bronchoscopy is a relatively new and non-invasive procedure that provides a three dimensional view of the internal walls of the tracheobronchial tree through the reconstruction of axial images. The objectives of the study are, 1) to study the diagnostic accuracy and advantage of virtual bronchoscopy over rigid bronchoscopy in the evaluation of children with suspected FBA and to plan for early management as it is a non-invasive technique;2) to study the clinical spectrum of children attending with suspected FBA. Methods: An observational study of 37 patients of age 12 yrs and below who underwent Virtual Bronchoscopy for suspected foreign body aspiration in the department of pediatrics and Otorhinolaryngology at MGM Hospital, Warangal is carried out for a period of 1.5 years during 2012-2013. Results: The common age of presentation was 1 - 3 years with male preponderance. History of foreign body was obtained in 64.86% of cases. Normal X-ray was found in 27.02% of cases. In 75.67% FB detected on rigid bronchoscopy was also revealed on virtual bronchoscopy. False positive percentage was 5.40% and false negative was 2.70%. Sensitivity and specificity was 96.5% and 75% respectively. Ground nuts were the commonest foreign bodies aspirated. Conclusion: Virtual bronchoscopy should be considered in cases with suspected foreign body aspiration, when chest X-ray is normal, to avoid needless rigid bronchoscopy. Virtual bronchoscopy is useful in screening cases of occult foreign body as it has sensitivity, specificity, and validity.

Endoscopic extraction of a submucosal esophageal foreign body piercing into the thoracic aorta:A case report

BACKGROUND Aorto-esophageal injury is a rare but life-threatening complication of esophageal foreign bodies,which typically requires open surgery.The best way to treat patients with this condition remains unclear.To date,few reports have described an aortic wall directly penetrated by a sharp foreign body.Here,we present a rare case of a fishbone completely embedded in the esophageal muscularis propria and directly piercing the aorta,which was successfully treated by endoscopy and thoracic endovascular aortic repair(TEVAR).CASE SUMMARY We report the case of a 71-year-old man with a 1-d history of retrosternal pain after eating fish.No abnormal findings were observed by the emergency esophagoscopy.Computed tomography showed a fishbone that had completely pierced through the esophageal mucosa and into the aorta.The patient refused to undergo surgery for personal reasons and was discharged.Five days after the onset of illness,he was readmitted to our hospital.Endoscopy examination showed a nodule with a smooth surface in the middle of the esophagus.Endoscopic ultrasonography confirmed a fishbone under the nodule.After performing TEVAR,we incised the esophageal mucosa under an endoscope and successfully removed the fishbone.The patient has remained in good condition for 1 year.CONCLUSION Incising the esophageal wall under endoscope and extracting a foreign body after TEVAR may be a feasible option for cases such as ours.

Endotamponades in pars plana vitrectomy for metallic intraocular foreign body associated with endophthalmitis

AIM: To study the criterion-reference of endotamponades in pars plana vitrectomy for metallic intraocular foreign body (MIOFD) associated with endophthalmitis. METHODS:Thirty-six patients of MIOFD with endophthalmitis accorded with Exclusion and inclusion criteria were retrospectively analyzed. A detailed analysis of the patients' natural factors, preoperative examinations, intraoperative endotamponades choice, postoperative complications and therapeutic effects was performed. RESULTS: BSS was used in 4 eyes without obvious retinal damage. There was no postoperative complication and their visual acuity (VA) was improved. Sixteen eyes that had mild retinal damage filled with C3F8 gas. The postoperative VA improved in 10 eyes (62.5%), 4 eyes (25.0%) remained unchanged and 2 eyes (12.5%) decreased. Only 2 cases occurred postoperative retinal detachment in gas group. Another 16 eyes with serious retinal damage were treated with silicone oil. Postoperative VA of 9 eyes (56.3%) improved, 3 eyes (18.8%) remained unchanged and 4 eyes (25.0%) decreased. The silicone oil group had higher incidence of postoperative complications, but the incidence of secondary treatment had no significant different between silicone oil and gas group. CONCLUSION: An appropriate choice of endotamponades in vitrectomy surgery for MIOFB with endophthalmitis is important for prognosis.

Intralenticular metallic foreign body: a case report

A case of retained intralenticular iron piece with signs of mild anterior uveitis at the time of presentation is reported in a 45 year-old man. His vision improved with topical cycloplegics and corticosteroids. After six months, his vision deteriorated grossly due to cataract formation. He regained good vision following removal of foreign body, extracapsular extraction with posterior chamber intraocular lens implantation. This case highlights the conservative management of the condition till the patient develops cataract resulting in visual disability; and good visual recovery following cataract surgery with intraocular lens implantation.

Foreign body granuloma in the tongue differentiated from tongue cancer:A case report

BACKGROUND Embedded foreign bodies in the tongue are rarely seen in clinical settings.An untreated foreign body can cause a granuloma which often presents as an enlarged tongue mass.However,if foreign body ingestion status is unknown,physical examination and magnetic resonance imaging(MRI)tend to lead to suspicion of tongue cancer,especially in older patients.Thus,differential diagnosis of an enlarged tongue mass is important,especially because it is closely related to the choice of treatment method.CASE SUMMARY A 61-year-old woman was admitted to the hospital with pain and noticeable swelling in the tongue that had persisted for over 1 mo.She had no previous medical history.MRI revealed abnormal signal intensities that were indicative of a neoplasm.Thus,the oral surgeon and radiologist arrived at a primary diagnosis of tongue cancer.The patient visited the Ear Nose and Throat Department for further consultation and underwent an ultrasound examination of the tongue.The ultrasonography was consistent with a linear hyperechoic foreign body which was indicative of an embedded foreign body(bone)in the tongue,even though the patient denied any history of foreign body ingestion.Complete surgical enucleation of the lesion was conducted.The mass which included a fish bone was completely removed.The post-operative pathological examination confirmed that the mass was a granuloma containing collagen fibers,macrophages and chronic inflammatory cells.The patient recovered without complications over a 2 mo follow-up period.CONCLUSION We report a rare case of foreign body granuloma in the tongue that was primarily diagnosed as tongue cancer.The MRI and ultrasound examinations revealed a piece of bone in the left lateral aspect of the tongue.The granuloma,which contained a fish bone,was completely removed via surgery and confirmed via biopsy.Differential diagnosis of the enlarged tongue mass was critical to the selection of treatment method.

Nasal septal foreign body as a complication of dental root canal therapy: A case report

BACKGROUND Currently,there have been no reports on foreign bodies found in the nasal septum after dental root canal therapy.Herein,we present an unusual case of a foreign body found in the nasal septum,which occurred after dental root canal therapy and two unsuccessful surgeries.CASE SUMMARY A 55-year-old man was referred to our department due to slight nasal discomfort that persisted for about 1 wk.Before consulting our department,the patient visited three different hospitals/clinics and underwent two surgeries that were not successful in removing a foreign body completely.A computed tomography scan was performed to detect the shift of the foreign body from dental root to the nasal septum,which resulted in the healing of oral inflammation and nasal septum discomfort.An endoscopic foreign body extraction surgery(3rd removal surgery)was then successfully performed,using a needle as the reference.No nasal reconstruction was required after the operation.Postoperative healing was uneventful.CONCLUSION Medical healthcare professionals should consider past medical history when dealing with foreign body cases.During septal foreign body extraction surgery,a needle could be used as a helpful reference.

Hepatic abscess caused by esophageal foreign body misdiagnosed as cystadenocarcinoma by magnetic resonance imaging:A case report

BACKGROUND Foreign bodies stuck in the throat and esophagus can be discharged through the digestive tract.Esophageal-lodged foreign bodies can cause secondary injury or detrimental response,with hepatic abscess being one such,albeit rare,outcome.Review and discussion of the few case reports on such instances will help to improve the overall understanding of such conditions and aid in differential diagnosis to improve patient outcome.CASE SUMMARY A 51-year-old female patient with pre-existing diabetes visited our hospital following a 15-d experience of chills and fever.Both plain and enhanced magnetic resonance imaging and color Doppler ultrasound examination of the liver and gallbladder revealed a space-occupying lesion in the caudate lobe of the liver(7.8 cm×6.0 cm×5.0 cm).Initially,a malignant tumor was suspected,but differential diagnosis was unable to exclude the possibility of hepatic abscess.Conservative anti-infection therapy produced a less than ideal outcome.Additional examination by hepatobiliary imaging with computed tomography suggested a foreign body present in the upper abdomen and hepatic abscess,and subsequent endoscopy revealed a sinus tract in the anterior wall of the duodenal bulb.Therefore,surgery was performed to remove the object(fishbone)and drain the abscess.After a 2-wk uneventful recovery,the patient was discharged.The final diagnosis was foreign body-induced hepatic abscess of the caudate lobe.CONCLUSION Differential diagnosis is important for hepatic masses,and systematic examination and physician awareness can aid in diagnosing and curing such rare conditions.

Unusual cervical foreign body-a neglected thermometer for 5 years:A case report

BACKGROUND Foreign body in the deep neck is mostly associated with accidental ingestion of the animal spiculate bone which penetrates the full-thickness of the aerodigestive tract into the fascial spaces of the neck.In general,perforation of the esophagus often results in periesophagitis and even fatal abscesses.The presence of a giant foreign body in the neck without obvious symptoms or complications for many years is rare.CASE SUMMARY We present the case of a 32-year-old man who intentionally swallowed a thermometer which was unable to be located by endoscopy at his initial visit.He had no remarkable symptoms for 5 years other than paresthesia and limited movement of the left neck until 7 d before this admission.The foreign body was removed successfully by the surgery.CONCLUSION The presence of a giant foreign body in the neck without obvious symptoms or complications for many years is rare.Both endoscopic and radiological examinations are essential for the diagnosis of alimentary foreign bodies.

Glass ampoule in urinary bladder as a foreign body

A wide range of objects have been inserted into the urinary bladder and urethra.Most foreign bodies in the lower genitourinary tract are self-inserted via the urethra as the result of erotic impulses,psychometric problems,sexual curiosity,or sexual practice while intoxicated.Here we report the case of a 32-year-old female with alleged history of insertion of glass ampoule in the urethra by the husband in eroticism which was removed with open surgery.This is the first case of its kind as per the literature available.
