Clinical features and outcomes of dogs with attempted medical management for discrete gastrointestinal foreign material: 68 cases (2018-2023)

OBJECTIVE

To retrospectively describe clinical characteristics of canine gastrointestinal foreign bodies (GIFB) that were successfully and unsuccessfully managed conservatively.

ANIMALS

68 client-owned dogs presented to the Texas A&M Small Animal Teaching Hospital between January 1, 2018, and October 1, 2023, for GIFB where medical management was attempted.

CLINICAL PRESENTATION

Medical records were reviewed for signalment, history, physical examination, bloodwork, diagnostic imaging, foreign body type, location, treatments, and outcome. Success was defined as the passage of the foreign body through the colon, while failure was defined as requiring surgery, endoscopy, or euthanasia.

RESULTS

Medical management was successful in 32 cases (47%; 95% CI, 0.32 to 0.66). Gastric dilation resolved in all success cases (n = 5 [100%]; 95% CI, 0.32 to 2.3) but did not resolve in any failure cases (13 [0%]). Small intestinal dilation resolved in all success cases (n = 13 [100%]; 95% CI, 0.53 to 1.7) but progressed in most failure cases (9 [75%]; 95% CI, 0.34 to 1.4). In the success group, 31 GIFB were nonlinear (96.9%; 95% CI, 0.66 to 1.4), while 1 was linear (3.1%; 95% CI, 0.001 to 0.17). In the failure group, 29 GIFB were nonlinear (80.6%; 95% CI, 0.54 to 1.16), while 7 were linear (19.4%; 95% CI, 0.08 to 0.4). Of the cases that elected surgery (n = 29 [42.7%]; 95% CI, 0.29 to 0.61), resection and anastomosis was performed in 3 cases (10.3%; 95% CI, 0.02 to 0.3). All cases that required resection and anastomosis were nonlinear GIFB.

CLINICAL RELEVANCE

Conservative management of GIFB provides a feasible treatment option and may be considered based on presentation, foreign body location, hemodynamic stability of the patient, diagnostic imaging, and type of foreign body.

Evaluation of the Quality and Readability of Web-Based Information Regarding Foreign Bodies of the Ear, Nose, and Throat: Qualitative Content Analysis

BACKGROUND

Foreign body (FB) inhalation, ingestion, and insertion account for 11% of emergency admissions for ear, nose, and throat conditions. Children are disproportionately affected, and urgent intervention may be needed to maintain airway patency and prevent blood vessel occlusion. High-quality, readable online information could help reduce poor outcomes from FBs.

OBJECTIVE

We aim to evaluate the quality and readability of available online health information relating to FBs.

METHODS

In total, 6 search phrases were queried using the Google search engine. For each search term, the first 30 results were captured. Websites in the English language and displaying health information were included. The provider and country of origin were recorded. The modified 36-item Ensuring Quality Information for Patients tool was used to assess information quality. Readability was assessed using a combination of tools: Flesch Reading Ease score, Flesch-Kincaid Grade Level, Gunning-Fog Index, and Simple Measure of Gobbledygook.

RESULTS

After the removal of duplicates, 73 websites were assessed, with the majority originating from the United States (n=46, 63%). Overall, the quality of the content was of moderate quality, with a median Ensuring Quality Information for Patients score of 21 (IQR 18-25, maximum 29) out of a maximum possible score of 36. Precautionary measures were not mentioned on 41% (n=30) of websites and 30% (n=22) did not identify disk batteries as a risky FB. Red flags necessitating urgent care were identified on 95% (n=69) of websites, with 89% (n=65) advising patients to seek medical attention and 38% (n=28) advising on safe FB removal. Readability scores (Flesch Reading Ease score=12.4, Flesch-Kincaid Grade Level=6.2, Gunning-Fog Index=6.5, and Simple Measure of Gobbledygook=5.9 years) showed most websites (56%) were below the recommended sixth-grade level.

CONCLUSIONS

The current quality and readability of information regarding FBs is inadequate. More than half of the websites were above the recommended sixth-grade reading level, and important information regarding high-risk FBs such as disk batteries and magnets was frequently excluded. Strategies should be developed to improve access to high-quality information that informs patients and parents about risks and when to seek medical help. Strategies to promote high-quality websites in search results also have the potential to improve outcomes.

Sharpnel splinter in the common bile duct

Foreign bodies are a rare cause of obstructive jaundice. In this case report, we present the case of a 59-year-old male who presented with abdominal pain and obstructive jaundice, which was later found out to be caused by an impacted shrapnel splinter in the common bile duct 7 years after a combat injury. To our knowledge, this is the first documented case from Syria. This case report is a reminder that impacted foreign bodies should be considered as a potential cause of obstructive jaundice in patients with previous combat injury.

Perforation of Meckel's diverticulum by an unusual foreign body: A case report and a review of literature

Key Clinical Message

Perforation of Meckel's diverticulum (MD) is rare, particularly by foreign body. High index of suspicion and thorough intraoperative assessment is needed in patients undergoing surgery for acute appendicitis, specifically when appendix appears normal.

Abstract

Meckel's diverticulum is the most common congenital anomaly of the gastrointestinal tract. While often asymptomatic, it can present with several complications. Perforation due to foreign body ingestion is rare but can have severe consequences if late diagnosis occurs. A 13-year-old male, initially suspected of acute appendicitis, was eventually diagnosed with perforation of MD by a wood splinter-like foreign body after intraoperative assessment. Histological analysis revealed ectopic colonic tissue within the MD, a finding whose implications are not well understood, in contrast with the well-established complications associated with ectopic gastric and pancreatic tissues. This case highlights the diagnostic challenges of MD, which can mimic acute appendicitis, emphasizing the need for high suspicion when faced with atypical clinical presentation such as foreign body-induced perforation. Although surgical resection of asymptomatic MD remains controversial, we recommend a case-specific approach based on risk factors to guide decision-making on surgical resection for asymptomatic MD.

Bronchoscopic retrieval of an aspirated tooth following high-speed motor vehicle accident

A 28-year-old man aspirated a tooth into his right lower lobe bronchus following a high-speed motor vehicle accident. Initial retrieval attempts failed with a flexible bronchoscope, but a cryoprobe successfully dislodged and retrieved the tooth. Cryoprobe should be considered for bronchoscopic foreign body removal when conventional methods are unsuccessful.

A pea in a peculiar place: Unusual case of left upper lobe bronchial foreign body

Key Clinical Message

Foreign body aspiration is common in old age, sometimes lodged in unusual locations like the left upper lobe bronchus when aspiration happens in a recumbent position. Computed tomography is the preferred diagnostic tool, while flexible bronchoscopy is effective for removing the foreign body.

Abstract

Tracheo-bronchial foreign body aspiration (FBA) is common in children and elderly, but often goes unnoticed due to vague symptoms and atypical imaging findings. We present a case of aspiration of pea in elderly presenting with acute symptoms. Computed tomography (CT) reveled an atypical site of foreign body (FB), that is left upper lobe bronchus and immediate removal of the FB was done using a flexible bronchoscope. The symptoms subsided after removal of the FB. Missed FBs can lead to chronic issues like pneumonia and airway obstruction. Advanced age, psychiatric illness, stroke, seizure disorder, and neuromuscular disease increase the risk of aspiration in older adults. Commonly, FBs get lodged in the right middle and lower lobes after aspiration due to vertical orientation of the airways. CT is a helpful tool for diagnosis of FBA and flexible bronchoscopy is effective in removal of the FB in elderly.

Minimally invasive removal of a foreign body in the pancreas using digital intelligent technology: a case report

Pancreatitis caused by a fish bone penetrating the posterior wall of the stomach and entering the pancreas is rare. We herein report a case involving a woman in her late 30s with an approximately 1-month history of recurrent upper abdominal pain. Initial evaluation at another hospital failed to identify the cause but raised suspicion of pancreatic cancer. Computed tomography, magnetic resonance imaging, and a detailed consultation led us to suspect that the patient's pain had been caused by inadvertent ingestion of a fish bone. We used three-dimensional visualization technology to determine the location of the fish bone and informed the patient of the lesion and surgical plan through a simulated surgical demonstration. During surgery, we applied augmented reality navigation technology to remove the fish bone by a minimally invasive approach. The patient was discharged on postoperative day 3. She was followed up by telephone 24 hours after discharge. Outpatient follow-up was performed 1 week after discharge and on day 30. The patient recovered well and developed no complications. This case shows that digital medical technology can be applied in patients undergoing surgical removal of a pancreatic foreign body. Such technology assists with preoperative evaluation, patient education, and intraoperative trauma reduction.

Water bead injuries by children presenting to emergency departments 2013-2023: An expanding issue

A 2023 product recall has described the risk for morbidity and mortality for children ingesting water beads. We aimed to describe water bead exposure and management trends in the United States. We used the National Electronic Injury Surveillance System (NEISS) to identify water bead injuries from 2013 to 2023. Inclusion criteria were ages 0-17 years, diagnosis of ingested object/foreign body, and the narrative word(s) suggested water bead(s). NEISS supplied weights and variance variables to generate national estimates. There were 226 water bead injuries (66% ingestion). Children under age 2 years comprised 29% of injuries. Multiple water beads were involved in 56% of cases. There was a significant uptrend in water bead injury frequency after 2020. Sixteen (7%) cases required escalation of care. Water bead injuries are rising and appear to affect children of all ages. Children aged less than 5 years appear most vulnerable.

Percutaneous ultrasound-guided anchor wire placement aids in the intraoperative localization of nonpalpable, superficial foreign bodies and abscesses in dogs

OBJECTIVE

To describe and evaluate the use of preoperative percutaneous ultrasound-guided anchor wire placement to aid intraoperative localization of superficial foreign bodies and abscesses in dogs.

ANIMALS

11 dogs.

CLINICAL PRESENTATION

In a retrospective observational study, the medical records of dogs that underwent surgical exploration of superficial abscesses, guided by anchor wire, between 2018 and 2023 were reviewed for clinical and histopathological findings and complications. Owners or veterinarians were contacted to collect long-term follow-up information.

RESULTS

11 dogs were included. Superficial swelling was the most common clinical presentation. Computed tomography and ultrasound revealed an abscess cavity and suspected foreign body in 9 dogs and an abscess cavity without evidence of a foreign body in 2 dogs. Anchor wires were placed in close proximity to the foreign body or inside the abscess. All documented foreign bodies were successfully located and retrieved. Two dogs suffered minor postoperative complications. No major intra- or postoperative complications were documented. One dog displayed recurrence of clinical signs, but no further surgical management was required.

CLINICAL RELEVANCE

Preoperative percutaneous placement of an anchor wire via ultrasound guidance was successful in aiding intraoperative localization of nonpalpable abscesses and retrieval of foreign bodies. This technique may decrease surgical time, minimize the surgical approach required, and increase the likelihood of successful localization.

Tracheal Stent Ingestion: Unveiling Complications and Innovations in Management

Airway stenting has become integral to the therapeutic endoscopic management of benign and malignant obstructive airway diseases. Despite the increased use of stents, the absence of clear guidelines for surveillance and maintenance poses the potential for unique stent-associated complications. Our case reports a rare incident of tracheal stent dislodgement, leading to its ingestion and unexpected discovery within the stomach. This case serves the purpose of shedding light on a rare yet potentially life-threatening complication and discussing types of stent and characteristics to enhance gastroenterologists' understanding of stent-related challenges and equips them to anticipate and strategize the appropriate course of action.

Ionised hypercalcaemia in a cat with extrahepatic biliary tract obstruction secondary to a bile duct vegetal foreign body

Case summary

A 10-year-old neutered female domestic shorthair cat was presented to our hospital with a 2-day history of anorexia, vomiting and lethargy. The biochemistry panel revealed increased hepatic enzyme activity and serum amyloid A concentration. Haematological values were within reference intervals. An abdominal ultrasound identified a hyperechoic spindle-shaped structure within the common bile duct and a suspected secondary subobstruction, associated with signs of intra- and extrahepatic biliary tract inflammation. During hospitalisation, the cat developed severe and sustained ionised hypercalcaemia. Exploratory surgery was elected as a result of the lack of clinical improvement, despite supportive treatment and suspected retrograde migration of the spindle-shaped structure. Two grass awns were extracted at the junction of an extrahepatic duct and the common bile duct via choledochotomy using intraoperative ultrasound guidance. A stent was then placed in the bile duct to prevent subsequent bile leakage. Histopathology of the liver revealed a moderate neutrophilic and lymphoplasmacytic inflammation with rare bacterial colonies. Escherichia coli was cultured from a bile sample. No specific cause of hypercalcaemia was identified. The cat recovered uneventfully from surgery. Hepatic enzyme activities and hypercalcaemia progressively decreased within a few weeks after surgery and remained within the reference intervals without treatment. Therefore, hypercalcaemia was suspected to be secondary to a foreign body-related granulomatous reaction.

Relevance and novel information

To our knowledge, only one other feline case report of biliary tract obstruction secondary to a biliary foreign body has been described in the literature. This is also the first case reporting the use of intraoperative ultrasound to localise a vegetal foreign body within the biliary tract of a cat. This case is also unique because of the onset of hypercalcaemia suspected to be secondary to a foreign body-related granulomatous reaction.

Lost and Found: A Case Report of the Journey of Two Teeth Into the Bronchus After a Road Tragedy

Traumatic foreign body aspiration (FBA) in adults is a rare yet potentially life-threatening event that requires prompt recognition and management to prevent adverse outcomes. While less common in adults compared to paediatric populations, traumatic FBA incidents often occur in occupational settings, post-trauma, or during high-risk activities, presenting with acute respiratory symptoms and varying degrees of airway obstruction. Diagnosis can be challenging due to the lack of classic symptoms and the potential for delayed presentation, necessitating a thorough history, a focused physical examination, and appropriate imaging techniques such as computed tomography (CT) and bronchoscopy. Prompt intervention is crucial to mitigating complications such as airway obstruction, pneumothorax, and respiratory compromise. Here, we describe an interesting case of a patient with a road traffic accident who aspirated two teeth and thought he lost them in this process. Surprisingly, two lost teeth were found after undergoing diagnostic procedures for mild shortness of breath, further causing aspiration pneumonitis.

Foreign body ingestion: A case of wine-cork ingestion due to chronic alcoholism leading to ileus

Ingestion of foreign bodies is a rare clinical problem in healthy adults. Less than 1% of cases need surgery due to perforation or obstruction. Here, we describe an unusual case of a wine-cork ingestion by a 54-year-old woman with a history of chronic alcohol consumption. Computed tomography (CT) of the abdomen and pelvis revealed foreign body (FB) in terminal ileum. The proximal part of the ileum was dilated due to obstruction. Laparotomy was performed, and the FB was removed without complications. Most ingested FBs spontaneously pass through the gastrointestinal tract. However, in rare instances, the FB can cause obstruction. In case of suspicion of serious complications such as obstruction and perforation, abdominopelvic CT should be used. The application of radiographic techniques in the identification of FBs and the assessment of potential complications plays a crucial role in expediting medical interventions for patients.

Meckel's "Wallet": A Unique Case of Intestinal Obstruction

While bowel obstruction is the most common surgical disorder of the small intestine, small bowel obstruction due to Meckel's diverticulum is a relatively rare occurrence. We encountered a compelling case of small bowel obstruction that turned out to be more complex than anticipated, involving a Meckel's diverticulum with some unforeseen findings. We followed standard guidelines for history-taking, examination, investigations, and management of the intestinal obstruction. After exhausting conservative treatment options, we opted for surgical intervention, and the unexpected cause of the obstruction took us by surprise. This case report highlights an exceedingly rare entity: Meckel's diverticulum precipitating uncommon complications.

CT Characteristics and Clinical Findings of Bronchopneumonia Caused by Pepper Aspiration

Purpose

To explore the computed tomography (CT) features of bronchopneumonia caused by pepper aspiration to improve the diagnosis.

Materials and Methods

28 adult patients diagnosed with obstructive pneumonia caused by pepper aspiration from January 2016 to September 2022 were enrolled. The CT characteristics of bronchial changes and pulmonary lesions caused by pepper were analyzed and summarized.

Results

Among 28 patients, the most common symptom was cough (26, 92.9%), followed by expectoration (23, 82.1%). Bronchoscopy revealed that peppers were mainly found in the bronchus of the right lower lobe (n = 18, 64.3%), followed by the bronchus of the left lower lobe (n = 5, 17.9%). In combination with bronchoscopy results, the pepper in the bronchus manifested as circular or V/U-shaped high-density, localized soft tissue, and flocculent opacification in 8 (28.6%), 16 (57.1%), and 3 (10.7%) cases on CT images, respectively. The bronchial wall around the pepper was thickened with localized occlusion (n = 19, 67.9%) and stenosis (n = 9, 32.1%). Regarding adjacent bronchi without peppers, extensive wall thickening with stenosis and/or occlusion was found in 23 (82.1%) cases. Distal pulmonary lesions frequently involved two or three segments (21, 75.0%) and mainly presented as patchy consolidation or atelectasis (24, 85.7%).

Conclusion

In combination to a history of eating peppers and clinical symptoms, bronchopneumonia caused by pepper should be highly suspected if U/V-shaped and annular high-density or localized soft tissue density is detected in the bronchi of the lower lobes, accompanied by extensive bronchial wall thickening, stenosis, or occlusion, and consolidation or atelectasis in multiple distal lung segments.

Perforation of the Terminal Ileum Secondary to Mucosal Damage of Enteroaggregative Escherichia coli and a Toothpick

Enteroaggregative Escherichia coli (EAEC) is a common form of E. coli that causes gastroenteritis and diarrhea worldwide. Biofilm formation on the intestinal mucosa initiates an inflammatory cascade in the gastrointestinal tissue, which has significant destructive effects on the mucosa of the small and large intestines. Small bowel obstruction and perforation due to a foreign body are uncommon, but the risk increases with pre-existing conditions such as the presence of intestinal strictures, inflammation, and mucosal ulceration. We present a unique case of acute enteritis from EAEC with mucosal ulceration and perforation because of co-ingestion of foreign body and impaction with the presence of stricture in the terminal ileum. This was treated with small bowel resection and primary anastomosis. The patient was successfully discharged from the hospital. The clinical features and pathological findings of enteric EAEC infection are described. To our knowledge, intestinal perforation and secondary peritonitis related to EAEC enteric infection, with mucosal ulceration and perforation secondary to co-ingestion of a foreign body with intestinal stricture, have not been documented. In this case, EAEC was associated with terminal ileum mucosal ulceration and complicated by perforation secondary to foreign body impaction along with ileal stricture. These compounding effects likely explain gastrointestinal tract perforation and secondary peritonitis.

A case report of live-stranded rough-toothed dolphin (Steno bredanensis) with plastic debris ingestion on the Pacific coast of Japan

A juvenile rough-toothed dolphin (Steno bredanensis) was live-stranded and rescued in Kanagawa Prefecture, Japan. From the results of diagnostic examinations, blood tests indicated that the dolphin was malnourished, dehydrated, and anemic. The dolphin died on sixth day of rescue despite treatment. At autopsy, 570 g of foreign material, including 34 pieces of cellophanes and plastic debris (PD), were found in the forestomach. Additional gross findings, including some endoparasitism and presence of accessory spleens were also identified. This is the first case in Japan which accidental ingestion of foreign bodies, including PD, was suspected to be the cause of death in a cetacean.

Transorbital penetrating intracranial injury involving bilateral frontal lobes with evisceration of right eye: A case report

Key Clinical Message

Timely diagnosis, multidisciplinary surgical intervention, and appropriate imaging are crucial in managing transorbital-penetrating intracranial injuries (TOPIs), minimizing morbidity, and optimizing patient outcomes.

Abstract

Transorbital-penetrating intracranial injuries (TOPIs) are rare occurrences with potential for severe neurological complications and high mortality rates. Prompt diagnosis and management are essential to mitigate adverse outcomes. Understanding injury patterns and employing appropriate imaging modalities are crucial for effective surgical planning and patient care. We present a case of a 22-year-old male mechanic who sustained a TOPI involving bilateral frontal lobes with evisceration of the right eye following a workplace accident with a metal cutter. Upon arrival at the emergency department, the patient exhibited vision loss in the right eye, proptosis, and a dilated pupil. Imaging studies revealed the trajectory of a metal arrow through the right orbital roof, necessitating surgical intervention. A multidisciplinary team performed bifrontal craniectomy with duroplasty to remove the foreign body and address associated injuries. Postoperatively, the patient received broad-spectrum antibiotics and anticonvulsants, leading to full recovery and discharge on postoperative day 10. TOPIs present unique challenges due to their rarity and potential for devastating consequences. Our case highlights the importance of timely diagnosis, meticulous surgical planning, and multidisciplinary collaboration in achieving favorable outcomes. Radiological imaging plays a crucial role in guiding treatment decisions and optimizing patient care. This report underscores the significance of early surgical intervention, antimicrobial therapy, and prophylactic measures in reducing morbidity and mortality associated with TOPIs.

Intriguing Encounter: Retrieval of a Crescent-Shaped Metallic Foreign Body From the Maxillofacial Region

This case report presents the clinical details and management of a 40-year-old male welder who presented with a foreign body lodged in his left malar region for eight months following a work-related injury. The patient experienced persistent pain, intermittent swelling, and occasional discharge, prompting medical evaluation. Radiographic imaging confirmed the presence of a metallic object, and surgical exploration under local anesthesia led to successful removal. Postoperatively, the patient experienced complete resolution of symptoms, highlighting the importance of prompt intervention in cases of foreign body impaction to prevent complications and improve patient outcomes.

The Endoscopic Removal of a Detached Dental Implant Cap in the Maxillary Sinus During the Waiting Period: A Case Report

Displacement of dental implants into the maxillary sinus is one of the common dental complications. However, it is rare that dental implants cause the displacement of multiple components due to separation. Here, we describe an unusual case of a 43-year-old man who had a missing implant in the maxillary sinus after an implant procedure. There was a two-week waiting period before we performed the removal during which the cap had unexpectedly separated from the body and freely moved into the ostium by sinus activity. The body was independently extracted intraorally. The remaining cap was secondly removed by utilizing nasal endoscopy. There were no complications in the postoperative period and the patient reported no symptoms of sinusitis after two months of follow-up. We experience unexpected events in the course of treating a displaced implant into the maxillary sinus. Our case report may provide several learning points for the removal of a missing implant.

Successful Removal of a Foreign Body Located in the Peripheral Airway Using Flexible Bronchoscopy with Virtual Bronchoscopy Navigation

A case in which a foreign body located in the peripheral airway of the lung was removed by flexible bronchoscopy using a virtual bronchoscopy navigation (VBN) system has been reported. The patient was a 60-year-old man. Chest radiography revealed an incidental foreign body in the left lower lung. Chest computed tomography with 1.0-mm slices was used to create a VBN system and confirm the foreign body in left B9biiαy, which was removed by flexible bronchoscopy. Thus, peripheral foreign bodies can be safely removed using flexible bronchoscopy by creating a VBN system in advance.

A Rare Laryngeal Foreign Body Case: Postcricoid Total Dental Prosthesis

In this case report, 60-year-old patient who aspirated total dental prosthesis into the postcricoid region was presented with patient's history, clinical findings, radiologic examinations and surgical treatment with comparison of literature data. To our literature knowledge, this is the first total dental prosthesis detected in postcricoid region. This was unusual because it did not cause any respiratory disorders such as laryngospasm and asphyxia, although it led to mucosal abrasions in a wide area of esophageus. Laryngoscope, 134:2331-2334, 2024.

Development of non-contact foreign body imaging base on photoacoustic signal intensity measurement

BACKGROUND

It is challenging to visually identify tiny and concealed foreign objects within the body due to their small size and subcutaneous location while they can cause infections.

METHODS

A non-contact photoacoustic system based on Rosencwaig-Gersho photoacoustic theory and dual modulator method is developed for detecting foreign objects in meat.

RESULT

The experiments conducted validate the successful development of this measurement technique with 10 μm spatial resolution and its corresponding mathematical model, demonstrating an 11% Mean Absolute Percentage Error (MAPE) in comparison to the experimental results. Dual modulator successfully regulates laser energy at MPE limit.

CONCLUSION

The utilization of non-contact photoacoustic signal intensity measurements enables the identification of foreign objects within the body. Further, the application of mathematical modelling can validate the measurement outcomes. These findings serve as a foundation for creating an affordable and straightforward foreign body detector.
