Foreign body migration to the genitourinary tract.

Foreign body migration from the gastrointestinal tract to any of several sites within the genitourinary tract has been well documented. We report 3 such cases involving the upper and lower urinary tract to highlight the varied presentations, manifestations and prognosis associated with this entity.

Sonographic detection of ingested foreign bodies in the inferior vena cava.

Ingested foreign bodies usually proceed uneventfully through the intestinal tract; complications rarely occur. The wide variety of clinical presentations they produce often make the diagnosis difficult. We report two cases of sonographic detection of foreign bodies in the inferior vena cava, namely one toothpick and one small (chicken?) bone, which probably caused a duodenocaval fistula. Both patients were initially investigated for recurrent septic episodes, weight loss, and deterioration of general condition.

Novel approach in the treatment of intravitreal foreign body and traumatic cataract: three case reports.

We present a novel surgical technique of simultaneous traumatic cataract extraction, internal magnet removal of the intraocular foreign body, and implantation of a posterior chamber intraocular lens in the eyes of three patients with traumatic cataract and ferrous intraocular foreign body retained in the anterior part of the vitreous body. Primary corneal wound repair, cataract extraction, anterior vitrectomy, removal of the intraocular foreign body through the corneoscleral limbal incision by using intraocular magnet, and intraocular lens implantation were performed. All intraocular foreign bodies and corneal entry sites were not larger than 3 mm. After a median follow-up of 13.6 months (range, 9-21 months), visual acuity ranged from 0.6 to 1.0. There were no early or late postoperative complications. According to our experience, an anterior approach in the surgical technique of simultaneous cataract extraction, intraocular foreign body extraction and implantation of a intraocular lens in the capsular bag is possible in selected patients with intraocular foreign bodies positioned in the anterior vitreous, behind the lens, with no associated retinal pathology.

[Use of Hopkins rod-lens coupled with grasping forceps sheaths for extraction of tracheobronchial foreign bodies].

OBJECTIVE: To study the clinical application of Hopkins rod-lens coupled with gasping forceps sheaths in the extraction of tracheobronchial foreign bodies. METHODS: Sixty-two patients with tracheobronchial foreign bodies were operated on with Hopkins rod-lens coupled with grasping forceps sheaths under direct telescopic view or TV watching. High frequency jet ventilation was used and BPs ECGs SaO2 were monitored in all cases. RESULTS: Sixty-two patients were all successfully operated on. The extraction was primarily successful in 90% of the cases; and secondarily successful in 7% of the cases. No death and serious complication occurred. CONCLUSION: Compared with conventional bronchoscopic foreign body extraction, this new instrument and technique make it possible for the operator to clamp and extract foreign body under direct telescopic view or TV watching. It has increased the accuracy and safety of bronchoscopic extraction of tracheobronchial foreign bodies.

Management of foreign body ingestion in children: experience with 42 cases.

Ingestion of foreign bodies occurs frequently in children, but there are no definite management guidelines. We reviewed 42 pediatric cases of accidental ingestion of foreign bodies with or without symptoms during the past 10 years. In decreasing order of frequency, the foreign bodies included: coins, sharp objects (needle, pin), bones (fish and chicken bone), metal object, food, seeds, plastic material, magnets, jewelry ring, and others. The majority of children were 5 years old or younger. At the time of presentation, the vast majority of objects were located in the esophagus. Sixty percent of the patients had symptoms, such as abdominal pain, vomiting and cough. Management included observation, esophagoscopy, panendoscopy, and laparotomy. Four patients (9.5%) had complications. One patient who ingested a magnet suffered from esophageal perforation with mediastinitis. Two had deep neck abscess due to esophageal penetration by bones. Another patient had hemorrhagic gastritis after swallowing a coin. All patients discharged after treatment, and none died.

Fc-receptor-bearing macrophages isolated from hypersensitivity and foreign-body granulomas. Delineation of macrophage dynamics, fc receptor density/avidity and specificity.

Foreign-body and delayed hypersensitivity granulomas were induced in mice; and the dynamics of macrophages isolated from dispersed, 1--4-week-old lesions was delineated. The size and histologic complexity of the lesions increased as shown: adjuvant greater than schistosome egg greater than methylated bovine serum albumin greater than bead. Esterase staining, spreading on glass, and the percentage of Fc-receptor--bearing macrophages present in the various granulomas reflected the same gradient. The Fc receptors were examined by rosetting with rabbit-antibody--SRBC complex (EA). Whereas more than 90% of the population of macrophages of the dermal adjuvant granuloma contained undiminished numbers of receptor-bearing macrophages throughout the 4 weeks, the percentage of macrophages that displayed receptors in pulmonary foreign-body (40%) and delayed hypersensitivity granulomas (70%) peaked at 1 week and subsequently declined. The EA rosetting of the foreign-body and delayed hypersensitivity granuloma macrophages was strongly inhibited by monomeric IgG2a-specific and weakly by aggregated IgG2b-specific mouse myeloma proteins. Also, macrophages of the delayed hypersensitivity granulomas rosetted in higher percentages with SRBCs coupled with monomeric IgC2a than with those coupled with aggregated IgG2b myeloma proteins. Macrophages of the foreign-body lesion did not react with aggregated IgG2b--SRBC. Rosetting with monomeric IgG2a--SRBC or aggregated IgG2b--SRBC could not be cross-inhibited by the myeloma proteins. Both the monomeric IgG2a--SRBC and aggregated IgG2b--SRBC complexes were readily phagocytized. Trypsin treatment of the macrophages inhibited rosetting with EA or myeloma-protein--coupled SRBCs. The display of Fc receptors on the granuloma macrophages seems to be related to the etiology of the lesion and the intensity and duration of the inflammatory reaction.

Presentation and management of aural foreign bodies in two Australian emergency departments.

OBJECTIVE: To survey and compare the type and management of foreign bodies found in adult and paediatric ears presenting to an Australian otorhinolaryngology and a general ED. METHODS: Retrospective case study with data collated from two centres. Chart reviews of a total of 330 patients presenting with aural foreign bodies to the ED of the Royal Victorian Eye and Ear Hospital and the ED of The Bendigo Hospital, both situated in the state of Victoria, Australia, were surveyed for patient demographics, foreign body description and referral and removal pattern. RESULTS: Two hundred and seventeen adults and 113 children were included in the study. The most common foreign bodies in children were beads, cotton tips, insects and paper, and in adults cotton tips, insects, cotton wool and silicone ear plugs. Flying insects were far more common in the Australian population than cockroaches found in surveys in other countries. Children were significantly more likely to have initially been seen by their Local Medical Officer than adults (P < 0.001) and to require a general anaesthetic for removal of the object(s) (P < 0.001). Adults were more likely to have associated otitis externa at the time of presentation (P < 0.05). CONCLUSIONS: Aural foreign bodies are a frequent presentation to the ED. Recognition of patients requiring early specialist referral is important. Adults present with a different profile of aural foreign objects to children and require different management. The use of cotton tips or cotton wool in the external ear canal and silicone ear plugs should be discouraged.

[Endoscopic removal of foreign bodies and intraoperative endoscopy (author's transl)].

Foreign bodies of the upper GIT are regularly extracted with endoscopes, provided, that they have neither left the pylorus, changed their form, nor perforated the wall. Endoscopic extraction is recommended when safe and spontaneous discharge is uncertain. Impacted rectal foreign bodies usually need proctologic or abdominal surgery. Intraoperative endoscopy should be limited to those organs that are not attainable by preoperative inspection like cholangioscopy and peroral jejunoileoscopy.

Esophageal foreign bodies.

OBJECTIVE: A retrospective review was performed on 180 patients from 1975 to 1997 to evaluate the diagnosis, and management of esophageal foreign bodies. METHODS: All patients except two were symptomatic and 145 of them were younger than 14 years of age. Plain films were performed in every patient with a suspected esophageal foreign body (EFB). In all patients, rigid esophagoscopy was done under general anesthesia once the diagnosis of impacted EFB is made. RESULTS: Fifty-five percent of the foreign bodies were coins. In children, the majority of impacted esophageal foreign bodies were located at the level of the cricopharyngeus muscle while in adults the site of impaction was the lower esophageal sphincter. The most common symptoms were vomiting and or regurgitation. Of the 180 EFBs encountered, 169 were extracted endoscopically, five were pushed into the stomach, five were not found, and one patient needed cervicotomy. There were no deaths in this series. Predisposing factors were found in 15 patients. Fifteen patients (8.3%) had benign strictures. In ten patients (5.5%), minor complications were encountered, none of which were esophagoscopically related. Alternative diagnostic and therapeutic modalities are discussed. CONCLUSIONS: All patients with a history of suspected foreign body ingestion should have direct endoscopic examination. If the EFB is not detected a thorough radiographic examination, including CT scan, should be performed to detect a possible intra- or extraluminal object. Preservation of the airway is regarded to be the most important consideration in esophageal foreign body management.

[Pulmonary reaction to foreign bodies].

The response of the pulmonary tissue in a continuous stay of foreign bodies in the lung is characterized by chronic inflammation of the pulmonary tissue, deformation of the bronchial tree, atrophic, hyperplastic and dystrophic changes in the ciliated epithelium and its metaplastic degeneration into multitratum squamous epithelium. Chronic inflammation of the lung would develop mainly in bronchial injury with a foreign body or in impaired bronchial patency. In localization of metallic foreign bodies extrabronchially their incapsulation usually occurs.

Laparoscopic removal of an intragastric foreign body with endoscopic assistance.

We report the successful laparoscopic removal of an intragastric foreign body. A 57-year-old woman who had accidentally swallowed her own partial denture was referred to our hospital for its removal. Laparoscopic removal of the foreign body was urgently performed with the assistance of oral endoscope, following an earlier failed endoscopic removal associated with subcutaneous and mediastinal emphysema. The foreign body was removed from the stomach through a gastrotomy. There were no perioperative complications. The patient was uneventfully discharged on the ninth postoperative day. Laparoscopic removal of an intragastric foreign body is a feasible and safe treatment, and can be an alternative choice following failed endoscopic removal.

[Clinical use of ultrasonic distance measurements for close-to-wall foreign bodies in the eye (author's transl)].

The X-ray localization of intraocular foreign bodies is based on an average-sized schematic eye. Whether or not a foreign body only reached or penetrated the rear wall of the bulbus often cannot be decided safely - even if X-ray checks included other than straight forward gaze directions. By means of ultrasound it is possible. 1. to measure exactly the real dimensions of the patients eye and to alter the X-ray localization scheme (W. Comberg's scheme) correspondingly. This improves the accuracy of the X-ray localization technique. 2. To localize the foreign body directly and exactly by presentation of its echo. Simultaneous presentation of the bulbus rear wall echo permits determination of the foreign body position. - A case record is given.

Intraocular metallic-appearing foreign bodies after phacoemulsification.

Intraocular metallic-appearing foreign bodies in the anterior segment were seen in six eyes after cataract extraction by two-handed phacoemulsification. These fragments produced no symptoms and had no clinically significant effect on visual function. Similar-appearing foreign bodies were experimentally produced by applying ultrasound power with a phacoemulsification handpiece to the surface of a cyclodialysis spatula in vitro. Microscopic examination of the phaco handpiece tip and cyclodialysis spatulas revealed numerous surface irregularities, suggesting a possible source of these fragments. These results suggest that instrument touch during phacoemulsification may be the cause of the fragments. Long-term follow-up of these patients is required to determine the overall effect of the fragments.

Clinical features and management of intraorbital foreign bodies.

PURPOSE: To review the clinical features and management of patients with intraorbital foreign bodies. DESIGN: Noncomparative interventional case series. PATIENTS AND METHOD: Forty patients seen at two regional orbital surgery departments with intraorbital foreign bodies were reviewed. MAIN OUTCOME MEASURES: Visual acuity, surgical interventions, and complications. RESULTS: Seventy-three percent of patients were younger than 30 years old. There were 22 metallic, inorganic; 5 nonmetallic, inorganic; and 13 organic intraorbital foreign bodies (IOrbFb) in this series. Thirty patients were seen at the time of injury, and 10 patients were seen in a delayed setting with orbital complications. Thirty-four patients had surgical removal of their IOrbFb either because of complications or easy surgical access. Six patients had no surgery because of posteriorly located inorganic foreign bodies. Thirteen patients had resultant blind eyes; 12 of these were blind from the initial trauma. CONCLUSIONS: Loss of vision in conjunction with IOrbFbs is usually a result of the initial trauma. All patients should have antibiotic therapy because of the high incidence of secondary orbital infections. Computed tomography is the best initial mode of imaging. Surgical removal is indicated for all organic IOrbFbs. Inorganic IOrbFbs should be removed if causing complications or if located anteriorly after discussion of potential surgical complications with the patient. Posteriorly located inorganic IOrbFbs should be left alone, unless they are causing significant orbital complications.

Sonographic detection of a foreign body in the urethra and urinary bladder.

Reported herein is a 41-year-old male who presented for ultrasound due to two episodes of lower urinary tract infections within a period of 5 months. The sonographic examination revealed an elongated foreign body in the urethra extending into the urinary bladder. Self-insertion of foreign bodies into the urethra is usually done for erotic stimulation. However, foreign bodies can be inserted by children due to curiosity and by mentally retarded people, patients with psychiatric disorders as well as by intoxicated patients and in confusional states. Due to embarrassment, the patients seek medical help only when they are symptomatic and hence some of the foreign bodies are removed only several months after insertion. Detection might be either by plain abdominal films when the foreign bodies are radiopaque or by the use of contrast media. In the case presented by us, this was done by sonography. Endoscopic removal of these foreign bodies is considered the treatment of choice. Recurrent or chronic unexplained urinary tract infections should raise a high index of suspicion to the possible existence of a foreign body in the urethra and/or urinary bladder.

Choking on pins, needles and a blowdart: aspiration of sharp, metallic foreign bodies secondary to careless behavior in seven adolescents.

OBJECTIVE: To review the demographics, pathophysiology and management of aspiration of sharp, metallic foreign bodies; to review prevention strategies. DESIGN: Case series and review of the related literature (1932-2006). SETTING: Tertiary care pediatric hospital. PATIENTS: All patients presenting to BC Children's Hospital with aspiration of sharp, metallic foreign bodies since 1998. RESULTS: The seven patients ranged in age from 11 to 15 years (mean 13 years). The two boys had been playing with other boys at the time of aspiration. One aspirated a thumbtack and one aspirated a homemade blowdart (which traveled from his carina to his subglottis with coughing). Three of the five girls had been holding thumbtacks or a darting pin between their lips while putting up posters or sewing. The other two girls, who aspirated thumbtacks, refused to provide a history. One was treated successfully 6 days after the aspiration. The other girl withheld the history for over a year, presented with hemoptysis and eventually required thoractomy and right main bronchotomy to remove the tack. All of the other patients were diagnosed and successfully treated by rigid bronchoscopy within 24h. (Two patients initially had a failed attempt at foreign body removal by flexible bronchoscopy at another hospital.) This is the second largest series of aspiration of sharp, metallic foreign bodies since at least 1966. Adolescents are still aspirating sharp, metallic foreign bodies because of the same behaviors described by Jackson and Jackson in 1932. Education about choking hazards is needed for this age group. CONCLUSIONS: Aspiration of a sharp, metallic foreign body is a serious injury which is best treated by rigid bronchoscopy. These injuries potentially could be prevented through education.

Use of a commercially available metal detector for the localization of metallic foreign body ingestion in children.

UNLABELLED: Metallic foreign body (FB) ingestion is a common occurrence in the general paediatric population. We have shown that the use of a commercially available metal detector is sensitive in localizing and confirming metallic FB objects in the digestive tract. METHOD: In a double-blinded randomized control trial, we used a commercially available metal detector to localize metal coins in the digestive tract in an animal model. Localization of the coins was confirmed using fluoroscopy. In 10 consecutive patients with metallic FB ingestion, detection and localization of the FB using the metal detector was compared with standard confirmatory radiographic imaging. RESULTS: Using a commercially available, hand-held metal detector, we were able to localize a metallic FB in the gastrointestinal tract with 100% sensitivity in both the animal model and in 10 paediatric patients.

Experimental study of high-resolution ultrasound imaging of hemorrhage, bone fragments, and foreign bodies in head trauma.

The accuracy of high-resolution ultrasound scans in detecting foreign bodies and hemorrhage within the brain was evaluated by comparison with computerized tomography (CT) scans and gross pathology. The test lesions were blood and foreign bodies consisting of bone, wood, and metal placed in the brain of an experimental animal. High-resolution ultrasound scans (10 MHz) performed in coronal and sagittal planes accurately delineated the position and spatial orientation of these foreign bodies and hemorrhage. Both hemorrhage and foreign bodies were echogenic compared to normal, hypoechoic brain parenchyma. Metal fragments had a highly characteristic echo pattern caused by sound reverberation within the object. Acute intracerebral hemorrhage produced an ultrasound image consisting of sharply circumscribed homogeneous echoes. The sonographic shape of intracerebral hemorrhage correlated closely with the area of increased density seen on the CT scan. High-resolution ultrasonography accurately delineated experimentally produced components of head trauma and may prove useful as an intraoperative imaging technique to facilitate surgery in head-injured patients.
