Injuries associated with MR imaging: survey of safety records and methods used to screen patients for metallic foreign bodies before imaging.

OBJECTIVE: The purpose of this study was to survey the methods used by academic institutions for identifying patients who might have metallic foreign bodies or other contraindications to MR imaging. We also sought to determine the types of MR-related injuries and any subsequent legal action that might have occurred at these institutions. MATERIALS AND METHODS: A survey on these issues was mailed to 207 academic institutions listed in the American Medical Association's Directory of Graduate Medical Education Programs. Institutions that did not respond by mail were contacted by phone. The survey requested information on the use of questionnaires, plain radiography, CT, and metal detectors for screening potential MR imaging subjects, as well as on any MR-related injuries and subsequent legal action. Responses were entered into a data base and response percentages were calculated for each question. RESULTS: The overall response rate for the survey was 99% (206/207). These 206 institutions have a total of 368 MR imaging units, with a mean number of 1.8 MR units per department (range, none to nine). Data from a total of 205 different sites revealed that all patients are screened before MR imaging with a written questionnaire at 93% of all institutions (190/205). For selected indications, 85% of departments (174/205) screen with plain film radiography of the orbits. For selected indications, 41% of facilities (83/205) screen with CT of the orbits. Patients are sometimes screened with a metal detector or magnetometer in 12% of the departments (24/205). Ten departments reported serious injuries relating to MR imaging. The most serious injury occurred when an oxygen tank near the magnet became a missile and struck a patient's face. Most injuries (nine of 14) were burns. Two institutions also reported adverse reactions to gadopentetate dimeglumine. Injuries prompted legal action against four of the 10 institutions. No injuries were related to intraorbital foreign bodies, vascular clips, or pacemakers in patients. CONCLUSION: These data demonstrate the lack of consensus on screening protocols before MR imaging. Accidents are uncommon, but most accidents that do occur are potentially severe and easily preventable. We recommend that all patients be screened by a written questionnaire followed by oral questioning before imaging to determine those who are at risk. Specific questions should investigate the possibility that patients have ferromagnetic foreign bodies or implants anywhere in the body that are electrically, magnetically, or mechanically activated. All facilities must maintain a high state of vigilance in an effort to prevent iatrogenic burns and injuries from ferromagnetic missiles.

Dairy products containers as a source of unusual esophageal foreign bodies.

Seven patients were treated during a period of three years in the Otolaryngology department of Tel-Aviv Medical Centre, Israel, for the ingestion of a strange, previously unknown foreign body. The objects had been inadvertently swallowed while eating certain dairy products such as yogurt or sour cream. This rigid, sharp pointed plastic object is a waste product which is punched out from the production line of the foods and their containers. The plastic object is radiolucent and, therefore, difficult to identify on standard roentgenograms. Fluoroscopic examination with a contrast medium was needed for its demonstration. Five patients underwent rigid esophagoscopy under general anesthesia for removal of the foreign body. In two other cases the object was extracted from the piriform sinus under topical anesthesia. This unusual foreign body, although uncommon, poses a potential medical hazard. A high index of suspicion is necessary to make the diagnosis when a patient presents with a history of foreign body ingestion while eating dairy products of soft consistency.

[Foreign bodies of the bladder and urethra. Apropos of 2 cases].

The bladder and urethra can be the site of various types of foreign bodies. The authors report two cases of low urinary tract foreign bodies. The first case concerned a young man with psychiatric disorders who introduced a condom into his bladder and the second case was an elderly patient with a history of self-dilation who introduced a safety pin into his urethra. In the light of these two cases, the authors review the diagnostic features and management of bladder and urethral foreign bodies.

[Radiopaque abdominal foreign bodies introduced by the enteral route. 4-year experience].

The aim of this work has been the comparison between the results found in literature and our experience with the introduction of radiopaque foreign bodies by enteral way into the abdomen. The kind of our patients, most of whom were in jail, the sufficient number of cases and the particularity of some of them have convinced us of the soundness of our experience and have persuaded us to briefly report it, with our observations and conclusions. The first thing we want to point out, on the basis of our study, is that the degree of radiopacity of a foreign body is more important than its dimensions as far as its visibility at X-ray examination is concerned. Another conclusive point we want to stress is that surgery is often needed to remove foreign bodies introduced by rectum, while most patients who ingest foreign bodies do not need surgery and expel what they have ingested, without complications, by rectal way.

An unexpected foreign body in the oesophogus: a case report.

An unusual case of foreign body in the oesophagus is reported. A history of dysphagia was absent although oesophageal obstruction was total; the retained foreign body was vegetable matter. An unusual radiological appearance, "the inverted wine-glass sign" is described. Pure water depletion was diagnosed there being dehydration combined with hypernatraemia (Na = 164MEq/L), normokalaemia (K+ = 4.2mEq/L), and acidosis (Serum bicarbonate = 10 mEq/L), as well as uraemia (220 mg%), and haemoconcentration (haemoglobin=18.5g%). Treatment with oesophageal lavage and intravenous fluids was successful.

Management of smooth-blunt gastric foreign bodies in asymptomatic patients.

Guidelines for management in the asymptomatic patient with a smooth-blunt gastric foreign body are not well established in the pediatric literature. Questionnaires were sent to pediatricians, family practitioners, pediatric gastroenterologists and pediatric surgeons with an over-all response rate of 62.2%. There was no agreement in regard to how long one should observe such patients before recommending intervention. There was no correlation of years of clinical experience and length of observation recommended either. Review of the pre-endoscopic literature revealed spontaneous evacuation in 93-99% of all types of foreign bodies in 1477 pediatric patients. An observation period of at least eight weeks should be strongly considered in an asymptomatic patient with a smooth-blunt gastric foreign body. Exceptions would include an anatomic abnormality of the gastric outlet, previous gastric outlet surgery as well as a possibly toxic object.

Colonoscopic extraction of foreign bodies from above the rectum.

There has been a considerable amount of experience with removal of rectal foreign bodies inserted transanally. Until recently removal of objects above the rectosigmoid junction has required laparotomy. A literature review reveals that since 1975 there have been 29 cases of colonoscopic removal of a variety of objects reported in fourteen publications. The authors have had experience with three cases of retained colonic foreign bodies (greater than 7 days) extracted using the colonoscope. All patients received preprocedure antibiotics and bowel preparation from below. All objects were removed using either the Olympus CF LB3R colonoscope or the Fujinon EVC-M videocolonoscope. The authors conclude that colonoscopic retrieval of foreign bodies is technically feasible, safe, less morbid, and less costly than laparotomy. This technique should be considered as the first step in management of these patients by endoscopic surgeons.

Bronchoscopic removal of foreign bodies in children: retrospective analysis of 822 cases.

At the Department of Thoracic and Cardiovascular Surgery of Hacettepe University, a total number of 822 pediatric bronchoscopies were performed from 1984 through 1990 for suspected foreign body aspiration. Of the children 65.3% were boys and 34.7% were girls ranging in age from one month to 14 years. Definitive statement of foreign-body aspiration was obtained from 394 patients. Unilateral hyperaeration, atelectasis, and unilateral parenchymal infiltration were the most common radiological findings. In all endoscopic procedures, a pediatric rigid bronchoscope was used under general anesthesia and controlled ventilation. Foreign bodies were found in 77.7% of the 822 patients. In the rest of the children inflammatory disorders were confirmed. The foreign bodies most commonly found in 639 patients were sun-flower seeds (21.1%), beans (10.4%), water-melon seeds (10%), and hazelnuts (9.8%). In our presented series, the incidence of non-fatal complication was 1.8%, apart from these patients 5 of them (0.6%) died after the bronchoscopic procedures.

[Surgery for intra-bronchial foreign bodies].

OBJECTIVE: The aim of this study was to evaluate the results of surgical treatment of intra-bronchic foreign bodies after unsuccessful endoscopic extraction. MATERIALS AND METHODS: Fifteen patients underwent surgical treatment of intra-bronchic foreign bodies in our department during a period of 10 years. There was 9 males and 6 females, the mean age was 20.27 years (range between 5 and 39 years), there were 8 right localizations and 7 left. The recurrent pulmonary infections were most frequent complaint of patients. RESULTS: Twelve pulmonary resections (including one pneumonectomy) were necessary because of the importance of pulmonary parenchyma destruction. There was one post-operative complication (one empyema) and the peri-operative mortality was nul. CONCLUSION: Surgical treatment of intra-bronchic foreign bodies must be used only after unsuccessful endoscopic extraction. The preventive measures are the best treatment.

Airway foreign bodies: what's new?

Tracheobronchial foreign body (FB) aspiration is a common problem in children and adults. The medical history is the single most predictive factor in the clinical suspicion of FB aspiration. The "penetration syndrome" defined by the sudden onset of choking and coughing with or without vomiting should prompt concerns for FB aspiration. Findings on radiographic imaging include visualization of a radiopaque FB, atelectasis, postobstructive changes, mediastinal shift, and pneumomediastinum. In the presence of a high clinical suspicion even with normal imaging studies, bronchoscopy should be performed for a thorough evaluation of the airways. Bronchoscopic extraction of airway FBs can be safely accomplished with both the rigid as well as the flexible bronchoscope in adults and children. Rigid bronchoscopy allows for control of the airway and provides excellent visualization with a variety of ancillary instruments available. Increasingly, both the adult and pediatric flexible bronchoscopes have been used successfully in the extraction of airway FBs utilizing urologic or bronchoscopic instruments. Airway control can be achieved with an endotracheal tube or a laryngeal mask airway. A delay in diagnosis increases morbidity including cough, wheeze, edema, and granulation tissue formation. Bronchoscopic evaluation and removal should be performed as soon as the diagnosis is suspected.

Foreign-body aspiration in adults.

Although a common problem in children, foreign-body aspiration is unusual in adults and is often overlooked as a cause of airway obstruction. Four cases of aspirated foreign bodies in adults are reported, outlining a range of clinical presentations and emphasizing the need to be aware of this condition in adults, especially in rural areas. Bones of small mammals or birds may be inhaled and patients frequently present after an asymptomatic interval of varying length, leading to delay in diagnosis. Prompt treatment using rigid bronchoscopy leads to rapid clinical and radiologic resolution of the problem.
