“…For patients in the 'fish bone negative' group, if there was a clear history of recent fish bone ingestion, it was assumed that the ingested fish bone had been swallowed and passed further down the alimentary tract; it has been shown that abrasion from an ingested foreign body produces the same symptoms as the presence of the foreign body itself. (1) When the risk factors between the 'fish bone positive' and 'fish bone negative' groups were compared using Fisher's exact test or chi-square test, the only risk factor that showed a statistically significant difference was the use of dentures. The 'fish bone positive' group had a higher proportion of patients using dentures (25/87 vs. 4/25, p = 0.04).…”

INTRODUCTIONIngestion of fish bones is a common clinical complaint among adult patients. The aim of this study was to evaluate the epidemiological and behavioural risk factors for fish bone ingestion. METHODS RESULTSThe wearing of dentures, the use of utensils to eat fish and the practice of deboning fish in one's mouth were found to be associated with an increased risk of fish bone ingestion.CONCLUSION To prevent the occurrence of fish bone ingestion and its possible complications, at-risk populations should be advised on the precautions to take when eating boned fish.

Fish bone foreign body (FFB) is the most frequent food-associated foreign body (FB) in adults, especially in Asia, versus meat in Western countries. The esophageal sphincter is the most common lodging site. Esophageal FB disease tends to occur more frequently in men than in women. The first diagnostic method is laryngoscopic examination. Because simple radiography of the neck has low sensitivity, if perforation or severe complications requiring surgery are expected, computed tomography should be used. The risk factors associated with poor prognosis are long time lapse after FB involvement, bone type, and longer FB (>3 cm). Bleeding and perforation are more common in FFB disease than in other FB diseases. Esophageal FB disease requires urgent treatment within 24 hours. However, FFB disease needs emergent treatment, preferably within 2 hours, and definitely within 6 hours. Esophageal FFB disease usually occurs at the physiological stricture of the esophagus. The aortic arch eminence is the second physiological stricture. If the FB penetrates the esophageal wall, a life-threatening aortoesophageal fistula can develop. Therefore, it is better to consult a thoracic surgeon prior to endoscopic removal.

“…Some authors report up to 100% sensitivity on retrospective review of their images [ 7 ]. Fishbones appear as high-density linear objects surrounded by inflammatory changes of the adjacent bowel and can be visualized on thin slice images of no more than 2 mm [ 8 , 9 ]. Multiplanar reconstructions can increase sensitivity further [ 8 , 9 ].…”

Intestinal perforation following the ingestion of fishbone is unusual and rarely diagnosed preoperatively, as clinical and radiological findings are non-specific. We report a case of a female patient post Roux-en-Y gastric bypass (RYGBP) for obesity, who presented with severe abdominal pain and guarding in left iliac fossa. Computed tomography (CT) suggested internal herniation with compromised vascular supply to the bowel. Exploratory laparotomy identified a perforation site in the blind loop of the RYGBP due to a protruding fishbone. After extraction, primary suture repair was performed. In retrospect, the fishbone was identified on CT but misinterpreted as suture line at the enteroenterostomy site. This case emphasizes that although rare, the ingestion of fishbone can lead to severe complications and should therefore be included in the differential for an acute abdomen. On CT, it should be noted that fishbone may simulate suture line within the bowel if the patient has history of previous surgery.
