Computed tomography, ultrasonography and plain radiography in the detection of foreign bodies in pork muscle tissue.

To evaluate the possibility to detect foreign bodies in superficial soft tissue a comparative study, including computed tomography, ultrasonography and plain radiography, is presented. Nine different materials, ranging in size from 2 x 3 to 3 x 10 mm, were inserted into pork muscle. All foreign bodies were detected and exact location was achieved using computed tomography and ultrasonography. In plain radiography wood was not visualised and exact location of all foreign bodies was not obtained. According to our results computed tomography and ultrasonography is useful in detecting foreign bodies in superficial soft tissue.

[Identification and removal of orbital foreign bodies using the CAS (Computer-Assisted-Surgery) system].

Identification and extraction of orbital foreign bodies can cause problems in special cases. Small, retroocular localized fragments can be hard to detect, severe bleeding and traumatically damaged anatomy can render orientation difficult. At the Department of Otolaryngology, Plastic Head and Neck Surgery of Aachen University Hospital we used the investigational new CAS (Computer-Assisted-Surgery) device in several such cases with good success. CAS is a new localizing technique designed to assist the head and neck surgeon during surgery providing real-time position information. The method is based upon a three dimensional volume model of the patient's skull generated by preceding computed tomography imaging procedures such as CT or MRI scan. Intraoperative correlation of 3D-model and the patient's skull allows for real-time position display of a surgical instrument on the monitor screen. Accuracy of the method has been experimentally determined to be within 1 mm. Thereby the surgeon is able to localize even small foreign bodies without extensive exploration. In the case of multiple foreign bodies the surgeon gets a simple documentation facility, which of the visible fragments have already been extracted. Medially placed foreign bodies could be removed via an endonasal approach. Encouraged by these results we recommend CAS for the extraction of orbital foreign bodies.

[The reason for the removal of springing foreign bodies in the esophagus].

The author described a group of 28 prisoners with the springing foreign bodies. In this group were follow foreign bodies diagnosed: so called anchors, crabs and crossbreeds. Three prisoners no consent to esophagoscopy and two, with symptoms of thoracic esophageal perforation, were treated in Thorax Surgery Department. 21 foreign bodies were removal esophagoscopical and 2 remaining were extracted by the lateral pharyngotomy. Own observations have confirmed the effectiveness of esophagoscopy in removal of the springing foreign bodies in the esophagus.

Self-extrusion of a foreign body from the upper digestive tract to the skin.

Migrated ingested foreign bodies from the upper digestive tract have the potential to cause life-threatening complications. Cases of spontaneous expulsion to the skin of the neck are very rare. We present an unusual case of an ingested foreign body that migrated out of the upper digestive tract and self-extruded via the skin of the neck. An approach to the safe management of such seemingly innocuous foreign bodies is discussed. This report highlights the message that non-found ingested foreign bodies should be treated seriously due to the possibility of migration and resulting complications.

[Posterior segment intraocular foreign bodies. Clinical and epidemiological features].

OBJECTIVES: To evaluate the epidemiologic factors, associated ocular involvement and visual results in patients with intraocular foreign bodies lodged in the posterior segment. METHODS: In this retrospective study, the clinical records of 21 patients admitted to the hospital with intraocular foreign bodies between August 1994 and March 1998 were reviewed and evaluated in regards to age, gender, type of injury, foreign body nature, need for surgical intervention, complications and final visual acuity. RESULTS: All the patients were males, with a mean age of 38.7 years and an average follow-up period of 15.04 months. The foreign bodies were caused by work accidents in 2/3 of the cases and 71.4% involved ferromagnet metal. Sixteen patients underwent vitrectomy to remove the intraocular foreign body. Final visual acuity was equal to or greater than 0.4 in 57.9% of the patients and there was no light perception in 15.7%. The principal late complications were retinal detachment (19.04%), pthisis bulbi (14.2%) and cataracts (9.5%). CONCLUSIONS: Most of the intraocular foreign bodies are found in young males as a consequence of work accidents. Most patients require vitrectomy to remove the foreign body and even though good visual results are obtained in many cases, other cases suffer severe visual loss.

Foreign bodies in the chest: how come they are seen in adults?

The radiologic and clinical findings of foreign bodies in the chest of children are well recognized. Foreign bodies in adults are infrequent, however, and the radiologic findings of these unusual circumstances have rarely been described. We classified various thoracic foreign bodies into three types according to their cause: Type I, Aspiration, Type II, Trauma or Accident; Type III, Iatrogenic. This pictorial essay will illustrate the radiologic findings and consequences of thoracic foreign bodies in adults, which have rarely been described in the radiologic literature. The clinical significance of thoracic foreign bodies will be also be discussed.

Selective upper endoscopy for foreign body ingestion in children: an evaluation of management protocol after 282 cases.

PURPOSE: Foreign body ingestion is a common problem in both children and adults. This study aims to evaluate a management protocol where endoscopic examination was only selectively used after routine direct laryngoscopy to minimize patient discomfort and the need for general anesthesia in children. METHOD: A management protocol for foreign body ingestion based on symptoms was introduced in 1998 and records of children admitted to a university-affiliated hospital between January 1999 and October 2005 with suspected foreign body ingestion were evaluated. Symptoms, radiologic and endoscopic findings, and outcome were reviewed. RESULTS: A total of 282 patients were admitted. The mean age of patients was 5.75 years (range, 9 months to 17 years). There were 167 boys and 115 girls. Based on our protocol, 84 (29.8%) patients required an upper endoscopy. Fish bones were most commonly involved (68.8%). Foreign bodies, which were either removed or dislodged, were found during upper endoscopy in only 25 (8.8%) patients overall. All patients had an uneventful outcome. No complications or mortalities were encountered. There were no readmissions for those who did not undergo endoscopic examination. CONCLUSION: It is safe to selectively perform upper endoscopy depending on symptoms when managing children with foreign body ingestion.

Migrated foreign body granulomas on mammography after injection in the cervicofacial area.

AIM: The purpose of this study was to describe the mammographic findings of localized foreign body granulomas in women who were injected with a foreign body in the cervicofacial area to flatten wrinkles. MATERIALS AND METHODS: The teaching files of our institutions were searched, and nine mammograms of migrated foreign body granulomas located. The mammograms were analysed, including the location, shape, size, distribution and depth of the high-density nodules. All these cases had undergone sonography. RESULTS: The migrated foreign body granulomas appeared bilateral (n = 6) or unilateral (n = 3), as oval or round high-density nodules, in the upper inner and/or upper central locations. The average size of the lesions was less than 5 mm in all cases. All nine sonograms showed multiple, round cystic nodules, less than 5 mm in size, with strong posterior shadowing from far upper central to the upper inner breast. Sonography of the lower neck revealed the anatomy could not be visualized due to the strong posterior shadowing in the skin and subcutaneous fat layer. CONCLUSION: Migrated foreign body granulomas appeared on mammograms as localized, multiple oval or round high-density nodules, less than 0.5 cm in size, in the upper inner and/or upper central breast. Breast sonography, including the sonography of the suspected cervicofacial area, is helpful in verifying migrated foreign body granulomas.

Removal of corneal foreign bodies following laser in situ keratomileusis.

PURPOSE: To report the outcome of uncomplicated removal of corneal foreign bodies in patients who previously underwent laser in situ keratomileusis (LASIK). METHODS: Nine eyes of eight patients presented with corneal foreign bodies after LASIK. RESULTS: In three patients, diagnosis of corneal foreign bodies was delayed due to reduced pain and symptoms. Removal of foreign bodies was performed with no flap-related complications. Corneal wound healing was normal. Final visual acuity was not decreased. CONCLUSION: Corneal foreign bodies can be removed safely and effectively from corneas after LASIK.

An unusual foreign body ingestion in a schizophrenic patient: case report.

The topic of foreign body ingestion has received extensive coverage in the areas of surgery, emergency medicine, and pediatrics. A subset of this topic, the intentional ingestion of foreign bodies, however, is much less common, and requires special evaluation and management. Here, we report a case of ingestion of a rolled, metal tuna can lid in a male prison inmate previously diagnosed with depression and paranoid schizophrenia. Following evaluation by the surgical team, the foreign body was removed by laparotomy and the patient was discharged back to the prison without complication. In many cases, ingestions of this type involve a command hallucination ordering the patient to swallow the foreign body. Interestingly, the patient in the present case reported auditory hallucinations commanding him not to swallow the can lid. On further investigation, we found that patient had a proclivity toward this swallowing behavior even prior to his incarceration. Early identification of inmates with this proclivity has important implications for treatment and prevention.

[Foreign bodies in the lower respiratory tract: experience based on materials gathered in the ENT department of the Poznań Higher School of Medical Sciences between 1945 and 1997].

258 foreign bodies were removed from the lower respiratory tract in ENT Department of Poznań High School of Medical Sciences between 1945 and 1997. The age ranged from 0 to 85 years, but the most numerous group (68%) was found between 0 and 10 years. 86.5% patients were admitted to hospital during first three days after inserting the foreign body. The longest time of foreign body existence inside the bronchus was a period of 18 years. The most often met foreign bodies were: bones, bean seeds, fruit stones, pieces of food, iron nails. Spontaneous evacuation of the foreign body took place in 4% of cases. 98% of foreign bodies were removed by means of rigid bronchoscopy. Bronchofiberoscopy was performed for diagnostic purposes or for taking out foreign bodies located in the peripheral parts of the bronchial tree. 3% of patients were referred to the further toracosurgery treatment.

Esophagoscopy for removal of foreign bodies in the pediatric population.

A retrospective chart review of children who had rigid esophagoscopy for potential foreign body ingestion from 1998 to 2001 was conducted at Children's Hospital of Michigan Detroit. All pediatric patients less than 11 years of age who presented with suspected foreign body ingestion in a hospital setting over a 4-year period were retrospectively studied. Patient characteristics noted included age, sex and clinical presentation. Pre-operative radiographic findings, esophagoscopy findings, clinical presentations and types of foreign bodies were recorded. A history compatible with foreign body ingestion dictates diagnostic endoscopy with or without radiographic confirmation, and an acceptable rate of performing esophagoscopy without finding a foreign body was found to be 6.2%.

Nonoperative treatment of retained radiolucent foreign bodies in lower limbs.

The management of radiolucent retained foreign bodies in feet is discussed. Two patients are presented in whom, despite negative initial exploration, cast treatment allowed the foreign bodies to extrude. Six further cases were discovered in a poll of other pediatric orthopedists. Cast treatment is an alternative to further surgery on the foot in search of the foreign body.

Laryngeal foreign body: an unusual complication of percutaneous tracheostomy.

Impaction of a foreign body in the larynx is a serious event. While inhaled foreign bodies may occasionally impact in the larynx especially in children, a laryngeal foreign body as a complication of percutaneous tracheostomy has not been reported in the literature. We describe the case of a fragment of a Seldinger wire retained in the larynx for two years following a percutaneous tracheostomy and review the literature on the complications of this procedure.

[Spiral CT and conventional CT in the preoperative imaging of intraocular metal foreign bodies].

PURPOSE: To compare the effectiveness of spiral CT versus conventional CT in the preoperative assessment of metallic intraocular foreign bodies. METHODS: Eighteen patients with penetrating eye injuries and suspected metallic intraocular foreign bodies were assigned to undergo either spiral CT or conventional CT in the axial plane. The spiral and the conventional CT data were transferred to a workstation, and reconstructions in the coronal and sagittal planes were performed. Additional direct coronal scanning was performed only when necessary for preoperative assessment. The quality of the axial as well as the reconstructed coronal and sagittal images was assessed for each imaging modality. The size of the foreign bodies was measured and compared to the actual diameter. Total examination time and radiation dose delivered to the lens were measured for each imaging modality. RESULTS: All foreign bodies were detected by each scanning modality on the axial and on the reconstructed planes. The quality of the axial images was similar for spiral and conventional CT. The spiral technique provided high-quality reconstructed images which allowed accurate localization of the foreign bodies in all cases. Reconstructions by conventional technique were inadequate for preoperative assessment. The examination time for the total orbital volume was 18 s for spiral CT and 52 s for conventional CT. Radiation dose delivered to the lens was 35 mGy for spiral CT and 56 mGy for conventional CT axial scanning. CONCLUSION: Spiral CT multiplanar imaging offers several significant advantages for the preoperative assessment of metallic intraocular foreign bodies compared to the conventional CT technique in clinical practice, including short examination time, minimized motion artifacts, reduced radiation exposure, and accurate localization.

[Unusual case of the long term presence of esophageal foreign body (non-radiopaque coin) in children].

The authors report an unusual case of a foreign body in the esophagus of a child present for longer than 2 years. As an infant this child had repair of esophageal atresia. She was examined and assessed 2 years ago for suspected foreign body swallowing. Chest and abdominal xrays did not show the presence of any foreign body. Now this child was re-admitted with a foreign body in the esophagus, a piece of meat. X rays showed narrowing at previous anastomosis site and dilatation proximally. At esophagoscopy after removal of the piece of meat, a coin was removed as well (50 Hungarian fills). This coin has low radiopacity so did not contrast well in soft tissue. It is worth pointing out that despite having a foreign body this child did not have any difficulty with swallowing and development was normal.

Foreign bodies in the airway. Five-year retrospective study with special reference to management.

The charts of 143 patients with foreign bodies in the larynx and tracheobronchial tree who were admitted to the Chidrens Hospital of Los Angeles during the period 1973 to 1978 were reviewed. Of these children 84 were male and 59 were female. One hundred were private patients and forty-three were clinic patients. Of these foreign bodies 60 were nut meat which is by far the most common foreign body of the tracheobronchial tree. All foreign bodies were successfully removed. One hundred twenty-six were discharged within the first 24 hours after admission and treatment. Fifty-one or 36% of these patients were discharged on the same day after the foreign body was removed. Sixty-two of the foreign bodies were in the left bronchial tree, while 55 were in the right bronchial tree. One hundred thirty-eight were endoscoped under general anesthesia using the apneic technique and five patients were treated with oxygen standby only because of severe respiratory obstruction. A detailed description of the use of apneic technique with profound muscle relaxation, the avoidance of preoperative medication and the team approach to ventilating the patients are all described. The advantage of general anesthesia, and the potential intraoperative and postoperative problems are reviewed. Of the total number of cases 13% were between 4 and 11 months of age, 44% were between 12 and 23 months of age and 57% were over 23 months of age.
