Fishbone Foreign Body Ingestion With Gastric Impaction and Intestinal Micro-perforation in an Adult Female: A Case Report

Risk factor analysis and model construction for fish bone foreign body in children's pharynx

ObjectivesThis study aimed to assess the risk factors for predicting the presence of fish bone foreign bodies and to develop a risk prediction model. MethodsData of 1405 children who underwent video-guided laryngoscope for suspected fish bone foreign body ingestion were retrospectively analyzed. Multi-factor logistic regression analyses were performed to analyze the risk factors for the presence of fish bone foreign body in patients, and a risk prediction model was established based on the results of the logistic regression analysis. ResultsThe results of the statistical analysis showed the presence of an ulcerated surface increased the risk of having a fishbone foreign body in the pharynx by approximately 55.36-fold (95 % confidence interval (CI): 15.78–194.24), followed by a clear chief complaint site, which increased the risk of having a fishbone foreign body in the pharynx by approximately 7.963-fold (95 % CI: 4.820–13.15), and a tingling sensation, which increased the risk of having a fishbone foreign body by approximately 7-fold (95 % CI: 3.483, 14.233). A clinical prediction model (nomogram) was developed and its validation was performed using receiver operating characteristic (ROC) curve analysis, in which an area under the curve (AUC) value of 0.808 indicated that the model had a great prediction capability. ConclusionThe predictive capability of a logistic regression model for the detection of fish bone foreign bodies following ingestion is significant. Clinicians can concentrate on monitoring these risk factors and implementing appropriate interventions to reduce the risks of patients presenting with fish bone foreign bodies.

Translocation of a fish spike from the pharynx to the thyroid gland: A case report

BACKGROUND A fish spike stuck in the throat is a common ear, nose, and throat (ENT) emergency. However, it is very rare for a fish spike to reach the thyroid tissue through the throat, which is very dangerous and can lead to pharyngeal fistula, cervical abscess, mediastinal abscess, and thyroid abscess. Proper and timely management can help reduce complications, especially in elderly patients. CASE SUMMARY In the case presented here, the causative factor was dentures, but improper management aggravated the condition. In the case presented here, an elderly woman with a history of accidentally swallowing fish bones for 20 d had a sensation of foreign bodies in her throat. Eventually, computed tomography (CT) of the neck showed that the left side of the thyroid gland had a dense shadow in the form of a stripe. CONCLUSION If a fishbone foreign body is not visible during endoscopic examination but the patient has significant symptoms, the surgeon should be aware that the fishbone may be lodged in the thyroid. To avoid a misdiagnosis, ultrasound, CT, and other tests can be used to clarify the diagnosis. T The first step in treating a fish bone in the thyroid gland is to determine the position of the foreign body and the extent of the infection, and to develop a personalized surgical plan for its removal. At the same time, scientific information should be made available to the general public so that people know that if a fish bone is accidentally lodged, they should not force it to be swallowed or be spit out by inducing vomiting, which are incorrect methods and may aggravate the condition or even cause it to migrate outside the cavity, leading to serious complications, as in this reported case.

Automatic Recognition of Concealed Fish Bones under Laryngoscopy: A Practical AI Model Based on YOLO-V5.

Fish bone impaction is one of the most common problems encountered in otolaryngology emergencies. Due to their small and transparent nature, as well as the complexity of pharyngeal anatomy, identifying fish bones efficiently under laryngoscopy requires substantial clinical experience. This study aims to create an AI model to assist clinicians in detecting pharyngeal fish bones more efficiently under laryngoscopy. Totally 3133 laryngoscopic images related to fish bones were collected for model training and validation. The images in the training dataset were trained using the YOLO-V5 algorithm model. After training, the model was validated and its performance was evaluated using a test dataset. The model's predictions were compared to those of human experts. Seven laryngoscopic videos related to fish bone were used to validate real-time target detection by the model. The model trained in YOLO-V5 demonstrated good generalization and performance, with an average precision of 0.857 when the intersection over union (IOU) threshold was set to 0.5. The precision, recall rate, and F1 scores of the model are 0.909, 0.818, and 0.87, respectively. The overall accuracy of the model in the validation set was 0.821, comparable to that of ENT specialists. The model processed each image in 0.012 s, significantly faster than human processing (p < 0.001). Furthermore, the model exhibited outstanding performance in video recognition. Our AI model based on YOLO-V5 effectively identifies and localizes fish bone foreign bodies in static laryngoscopic images and dynamic videos. It shows great potential for clinical application. 3 Laryngoscope, 134:2162-2169, 2024.

Fishbone retention in the hypopharynx with abscess formation in the thyroid gland: A case report and literature review

Introduction: Among foreign bodies ingested by adults across the world, the most common is a fishbone foreign body. It’s most common location of impaction often being within the throat in areas such as the tonsils, tongue base, vallecular area, pyriform fossa, and cricopharyngeal area. Aim: To present the case of the fishbone embedded in the rare location, our clinical management and summarised approach to fishbone that migrates outside of the oesophagus. Case report: 76-year-old female was admitted to the hospital with a fishbone foreign body that was retained in the hypopharynx with abscess formation in the thyroid gland. The patient was treated successfully with direct rigid pharyngolaryngoscopy. Discussion: In most cases fishbone foreign bodies are easy to manage with a direct approach. Impacted fishbones may be more challenging as they can migrate deeply and can cause further complications requiring endoscopic approaches and even open surgery. Conclusions: It is important to examine and diagnose a patient accurately to reduce future complications of embedded foreign bodies. The proposed summary of management can be useful.

Is a fish bone at a parallel angle in the throat more likely to fall out automatically？

To investigate the factors influencing the spontaneous expulsion of fish bone foreign bodies in the throat of children.A retrospective cohort study was conducted between January 2018 and December 2021 of children hospitalized with fishbone foreign bodies in the throat, and subsequent electronic rhinolaryngoscopy to analyze the factors influencing the spontaneous expulsion of these foreign bodies.The effect of foreign body angle on the rate of dislodgement was found to be statistically significant. Parallel angle was more likely to dislodge relative to vertical (RR = 2.495, 95% CI 1.515-4.109, P = 0.000); inclined angle was more likely to dislodge relative to vertical (RR = 2.121, 95% CI 1.284-3.505, P = 0.003). For the three fish bone foreign body angles (vertical, inclined, and parallel), the percentage of dislodgement showed a linear trend (0.278, 0.600, and 0.723), indicating that the percentage of dislodgement appeared to increase with the increase of fish bone foreign body inclination angle (Ptrend = 0.000).There is a high rate of natural expulsion of fish bone foreign body from children's throat, and the rate of expulsion increases with the increase of the foreign body inclination angle.

Diagnostic Performance of Digital Radiograph and Low-Dose Computed Tomography for the Diagnosis of Fishbone Retention in the Oropharynx.

Introduction Fishbone foreign body retention is one of the most common problem with various clinical manifestations from asymptomatic, abscess formation, and perforation to mediastinitis with subsequence morbidity and mortality. Accurately identifying the location of the fishbone leads to precise removal, which, in turn, prevents serious consequences. Digital radiographs have been widely used for diagnosis, but many studies show poor sensitivity. Object The present study was designed to compare the diagnostic performances of digital radiograph and low-dose computed tomography (CT) for fishbone retention and to demonstrate the radiation dose of the two modalities. Methods We collected 2 pieces of fishbone from each of the 15 species commonly eaten in Southeast Asia. We embedded each fishbone in a fresh pig's neck, then subjected the pig's neck to lateral soft tissue neck digital radiograph. The locations to embed included tonsil, base of tongue, and upper esophagus. Then, we subjected the same specimen to a CT scan. Two experienced radiologists interpreted each image. Results Visibility in the digital radiograph group was 13%, and in CT images group, it was 87% regardless of the locations. The average radiation dose from digital radiographs was 0.4 mGy (radiation dose field), while from CT images it was 8.6 mGy (CT dose index). Conclusion Most of the common fishbones in Southeast Asia could not be visualized by digital radiograph when embedded in the neck. Computed tomography scans demonstrated better diagnostic performance of fishbone retention compared to digital radiographs, regardless of the embedded location.

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

BackgroundFish 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 designRetrospective, observational, monocentric study.MethodsFrom 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.ResultsFish 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%).ConclusionThe 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.

Abdominal CT manifestations in fish bone foreign body injuries: What the radiologist needs to know

Fish bone is one of the most common foreign body ingestions encountered in the emergency department. Fish bone perforations occur most commonly in segments with acute angulation like the ileocecal region and rectosigmoid junction and can present acutely with obstruction and free air or with chronic complications like abscess and sepsis. Radiologists should be familiar with the high-risk clinical scenarios, the CT appearance of radiopaque fishbones, and the spectrum of imaging findings related to gastrointestinal (GI) tract so as to direct management and timely referral to GI endoscopists and surgeons.

Laryngeal perforation in a cat due to a fish bone foreign body

AbstractA two‐year‐old domestic shorthair (DSH) cat was presented with a three‐day history of anorexia and cough after having a meal of raw fish. Clinical examination revealed stridorous breathing and excessive salivation. On external examination, the area surround the larynx appeared oedematous, palpation of this area seemed painful and elicited a dry cough. Laryngoscopy examination revealed laryngeal oedema, normal laryngeal function and an intralaryngeal foreign body. The foreign body was protruding from the ventral larynx, and 5 mm was visible. Lateral radiography of the cervical region depicted subcutaneous emphysema and a foreign body, which was bone opacity, in the larynx. Surgical exploration of the ventral larynx revealed perforation of the thyroid cartilage due to a fish bone that was removed, and the laryngeal wound was closed with sutures. After a follow‐up of 1.5 years, the cat was reported to be free of clinical signs.

Investigative strategies for fish bone foreign bodies during the coronavirus disease 2019 pandemic: an analysis of ENT UK guidelines.

By nature of their specialty, otolaryngologists are disproportionately exposed to coronavirus disease 2019 through aerosol-generating procedures and close proximity to the oropharynx during examination. Our single-centre, retrospective study analysed the pertinence of guidelines produced by ENT UK to improve the investigation and management of suspected upper aerodigestive fish bone foreign bodies during the coronavirus disease 2019 pandemic. Our results demonstrated 43.3 per cent (n = 13) low-risk cases and 56.7 per cent (n = 17) moderate-risk cases. Nine fish bones (two low risk, seven moderate risk) were found; none of these were confirmed with X-ray and three (moderate risk) required nasoendoscopy for diagnosis. One patient required rigid pharyngoscopy. This study confirms that soft tissue neck X-ray and flexible nasoendoscopy are unnecessary in low-risk cases; however, early nasoendoscopy in higher suspicion cases is appropriate. Recommendations are made about the long-term sustainability of these guidelines, and additional measures are encouraged that relate to repeat attendances and varying prevalence of coronavirus disease 2019 in the hospital catchment area.

Endoscopic removal of a fish bone foreign body in the hypopharynx with the modified Killian's method

Observing the entire circumference of the hypopharynx is usually difficult because most of the area is anatomically closed in the resting state. The modified Killian's method, consisting of a combination of the modified Killian position, head torsion, and the Valsalva maneuver, is a recently proposed procedure to improve the endoscopic view of the hypopharynx. A fish bone, which was invisible under regular endoscopy but was identified by CT, was successfully observed and removed under the modified Killian's method in a 71-year-old female. This method can be applied to diagnose and treat benign hypopharyngeal disease such as fish bone foreign body in addition to the detection of cancer.

Obstructive Sialadenitis of Submandibular Gland Due to a Nail-like Fish Bone Foreign Body: A Rare Case Report

Introduction: Foreign body-associated sialadenitis of submandibular gland is not often and scarce within the literature. In this study, a report of a piece of Nail-like fish bone foreign body entering the Wharton’s duct causing an acute sialadenitis is presented.&#x0D; Foreign bodies must be explored and all suspected areas must be examined carefully for avoiding secondary problems and surgeries in the future.&#x0D; Foreign bodies in the oral and maxillofacial region are often experienced after trauma and dental treatment.&#x0D; Case Report : We describe a case of obstructive sialadenitis in the submandibular gland caused by penetration of a fish bone in a 68-year-old man. He had swelling and spontaneous pain in the left submandibular region. The radiographic examination didn't show foreign body in the submandibular gland. Initially, we diagnosed obstructive sialadenitis in the left submandibular gland and the study suspect that salivary stone might be the cause of this swelling so compressing and milking of Wharton duct. The foreign body measured 1.3 cm *3 mm*2 mm and was a nail-like object. On pathological examination, the foreign body was found to be a fish bone (cartilage-like organic material).&#x0D; Conclusion: This case demonstrated that precise and proper inspection and examination, milking and then paying attention to the secretion of salivary gland lead to proper diagnosis and after that suitable treatment, so this could reduce costly assessment and treatment, also lessen bewilderment of the patient.
