Accidental or intentional ingestion of a foreign body is one of the most common emergency situations for endoscopists. In most cases, a conservative approach should be taken, since objects will generally pass through the intestinal tract without incident.1 The need for retrieval is mainly determined by the characteristics of the object ingested, such as its size and shape, the presence of sharp-edged or pointed objects, or the time elapsed since ingestion. Other factors to be taken into consideration are the clinical situation of the patient, or the locations of the object within the digestive tract. Certain ingested objects also require special consideration. For example, batteries and magnets nearly always require endoscopic extraction, while drug packets should always be left to transit naturally due to the risk of breakage and poisoning. A common situation is ingestion of metallic and/or sharp objects for the purpose of self-harm, above all in inmates in prison hospitals or psychiatric patients. In the case of large, pointed or sharp objects, retrieval is mandatory. This is usually performed endoscopically, with surgery being the last resort if endoscopy fails due to complications or the size and characteristics of the ingested object.2,3 We present here a rare case of endoscopic extraction of several, large, sharp objects.

A 37-year-old man, a prison inmate, was taken to the emergency room following ingestion of several metallic objects. The patient had a history of endoscopic extraction4 and gastric surgery in similar circumstances. The patient reported no symptoms. Simple abdominal X-ray showed a sharp-edged, 14cm long metallic object and at least 2 other sharp, flat objects measuring at least 20mm in width. Despite its limitations, endoscopy was considered the safest extraction method, with a surgical team on stand-by if the procedure failed.

The patient was taken to the operating room, anaesthetised and intubated. Endoscopy was performed (Fig. 1A) with a standard Olympus GIF-H190® gastroscope, 9.2mm diameter, 2.8mm working channel, and an Olympus GIF-2T160® two channel therapeutic gastroscope, 13.2mm diameter with 2.8 and 3.7mm working channels, a US endoscopy® overtube, 2cm calibre, and a rubber hood attached to the tip to protect objects that exceed the diameter of the overtube.5 Using this equipment, we successfully retrieved several sharp objects (Fig. 1B). We decided to first extract the larger, longer, pointed objects, as this was technically more complex and more likely to cause injury to the gastric wall. Following this, the flat objects were extracted in descending order of size.

The 2 largest objects were retrieved through the overtube, using a polypectomy snare and a conventional endoscope. The third object retrieved, which was one of the sharp, flat objects, was shorter and wider than the previous 2, and during extraction became lodged in the overtube after grasping it with a conventional polypectomy snare and large forceps passed through the two channel gastroscope, thus making it difficult to manoeuvre the object. Unsure whether the lower end of the object protruded from the overtube while still in the gastric cavity, which would have made it highly risky to extract it en bloc, we used a Siemens Arcadis Varic® digital fluoroscopy system to confirm that it was wholly enclosed in the overtube, and were subsequently able to extract it without complications, The smaller objects were retrieved with the help of the rubber hood attached to the tip of the endoscopy, using a snare and forceps.

The decision of whether to use endoscopy or surgery to extract sharp or pointed metallic objects should be based in each case on the likelihood of success, possible complications and the expertise of the endoscopist who will perform the procedure. The airway should be maintained with orotracheal intubation, and a flexible, front-view, single or dual channel endoscope should be used.2,4
