“…In the present study, we have shown the advantage of CT in the detection of fish bones in the oesophagus. The results obtained in the present investigation are also supported by previous studies (Gamba et al, 1983;Braverman et al, 1993;Nakabayashi et al, 1996). As mentioned previously by many authors, roentgenographic examination did not show the existence of fine fish bones clearly in many cases.…”

“…Gamba et al (1983) reported a case of an oesophageal foreign body, a piece of rib bone present for about three years, which had escaped prior detection by plain chest radiography, barium swallow, and oesophagoscopy. In this case, the foreign body was finally detected by means of CT. Because of the greater contrast resolution of CT, calcified objects not seen on conventional radiographs can be found on CT scans (Gamba et al, 1983). CT image reconstruction also eliminates the superimposition of overlying structures that may obscure a foreign body.…”

The usefulness of computed tomography (CT) in the diagnosis of fish bone impaction in the oesophagus was evaluated. Thirty-two patients were examined by plain X-ray followed by direct oesophagoscopy for suspected fish bone impaction. Among 25 cases in which fish bones were actually removed, foreign bodies were not clearly demonstrated by plain X-ray in 14 cases (56 per cent). Eleven cases underwent CT prior to the oesophagoscopic examination. Fish bones were clearly demonstrated by CT in all patients. CT also clearly visualized secondarily-induced inflammatory changes in the neighbouring structures. In order to confirm this result, we made a simulation model of oesophageal fish bone impaction, using fish bones of three different species surrounded by a water bag. In comparison with plain X-ray, CT depicted a superior image of fine fish bones and provides extremely useful information for the management of impacted fish bones in the oesophagus.

“…There was a significant false‐positive rate of 19% and, more important, a false‐negative‐rate of 55%. This compares unfavorably with CT in the detection of foreign bodies in particular fish bones 10‐12 . The role of CT for the treatment of the patient with a fish bone impacted in the cervical esophagus has been clearly demonstrated by our study and supported by previous reports 10 .…”

The role of CT for the treatment of the patient with a fish bone impacted in the cervical esophagus has been clearly demonstrated by our study and supported by previous reports 10 . The CT scan provides the dual benefit of not only localizing the object, but also helping to ascertain the presence of any complications that may have arisen as a result of the impaction.…”

“…The percentage of false positive results in this study was 22%. (7,8,9) Studies have found that plain film is false negative in 30 to 55% of cases and false positive in 24% cases. 5(8%) cases showed indirect evidence of foreign bodies in digital X-ray in this study.…”

INTRODUCTION:A foreign body is an endogenous or exogenous substance incongruous with the anatomy of the site where it is found. Foreign body ingestion can affect persons of any age. Despite major advances in diagnostic and therapeutic modalities, foreign body ingestion still causes significant dilemmas in the diagnosis and treatment. Multiple factors play role in the lodgment of these foreign bodies in the food passage. They are diet factor, dental factor, and inebriation and age factors to name a few. Preexisting strictures of esophagus is another local cause of impaction of F.B. The signs and symptoms of foreign body ingestion are quite diverse and often very non-specific. They include complete esophageal obstruction with overflow of secretions and aspiration, to mild odynophagia or dysphagia. Esophageal foreign bodies are most frequently located at the narrowest portion of the esophagus, the level of the crico-Pharynx sphincter. Rarely serious complications of such as mediastinitis, Pneumothorax, plural effusion, lung or mediastinal abscess, or massive hemorrhage due to a vascular fistula may occur before a thorough investigation is launched. Digital X-rays in two dimensions are useful in the diagnosis. CT scanning and MRI are rarely used in the evaluation of foreign bodies in the aero digestive tract, but are indicated in the event that the object is not found during endoscopic examination and migration from the airway or esophagus is suspected. In 1936 Chevalier Jackson described endoscopic techniques for the removal of foreign bodies. Since then this has remained the safest and most trusted method of treatment. Techniques for foreign body removal employing fiber optic endoscopes have been described. The treatment of choice for foreign bodies of the upper aero digestive tract is reasonably prompt endoscopic retrieval in the operating suite under anesthesia. Endoscopy is performed as an emergency in case ingestion of disc batteries with esophageal lodging and signs or symptoms of esophageal perforation to avoid further complications and strictures. AIM: To evaluate the sensitivity and specificity of digital Xray in detecting all foreign bodies impacted in throat and esophagus. To assess the factors leading to false positive findings in Digital X-rays in the study subjects; to evaluate the role of digital X-ray in detecting complications. MATERIALS AND MEHODS: 208 patients attending Government Hospital of Kozhikode with history of foreign body ingestion are included in the study. Thorough history taking, clinical examination followed by radiography with the help of Digital X-rays to locate the foreign body is done. Fish bones being common in this part of Kerala, emphasize is made to find the specificity and sensitivity of using digital X-rays in locating fish bones in food passage. Conservative management in patients showing minimal symptoms is studied. The incidence of Complications among the patients is studied. OBSERVATIONS: The sensitivity of digital X-ray in detecting fish bone foreign bodies i...
