Ingestion of foreign bodies that lodge in the upper gastrointestinal (GI) tract is a common clinical situation. A 34 year-old male who swallowed an unusual huge spring in a bet without any symptoms. There were no available endoscopic overtubes or devices for this kind of huge foreign object to protect the esophageal mucosa from laceration during the retrieval procedure. Fortunately, it was removed by endoscopy without severe complications. We present the case to arouse further concern about such as huge foreign bodies, how to be extracted more safely and less invasive.

Foreign bodies ingestions is a commonly encountered emergency in the endoscopic department. Most objects pass through the upper gastrointestinal (GI) tract spontaneously, but 10%-20% of ingested foreign bodies need endoscopic or surgical removal . Here, we report an unusual large foreign object lodged in the stomach for nearly a week, which was safely removed by endoscopy fortunately.
A 34 year-old single man with a history of drug abuse presented to the endoscopic center accompanied by his mother. He swallowed a huge spring with hooks which made him a winner of a bet with his friends on July 16, 2015. He had no complaints of abdominal pain, nausea, odynophagia, dysphagia, chest pain or reflux. He was at home until the bet was known by his mother five days later. He was taken to the hospital by his mother on July 22, 2015. On initial presentation, the patient talked little and denied any symptoms. Physical examination was normal except mild abdominal tenderness to moderate palpation without rebound tenderness or guarding. Laboratory results were normal except the positive anti-HCV. An electrocardiogram and the Xray of chest showed no abnormal signs. The abdominal plain radiography revealed a large spring with a hook at both ends in the stomach, which measured approximately 18cm X 2cm, and there was no radiographic evidence of perforation (Figure 1). CT scanning confirmed the unusual foreign body and showed no liver cirrhosis and esophageal varices. Considering the potential risks of the upper endoscopic procedure, including the possibility of esophageal and/or gastric perforation, mucosal injury and bleeding, the inability to retrieve the foreign body, the patient and his mother insisted on the decision to attempt the endoscopic removal of the spring and the written consent was signed by both the patient and his mother. The patient underwent a upper endoscopy under conscious sedation using propofol and sufentanil without endotracheal intubation. Cardiopulmonary function was monitored with pulse oximetry throughout the procedure. The foreign body was located in the gastric body with its hooks embedded in chime (Figure 2). After irrigation with the saline, the hook of the proximal end was exposed, which was easy to be grasped by the alligator forceps which was passed through the accessory channel. It was easy to pull the spring into the esophagus without obstruction, but it was difficult to pull out through the pharynx. After multiple attempts, it was finally retrieved with the endoscope and the alligator forceps holding the foreign body together (Figure 3).
On repeat endoscopic examination, minor mucosal injuries were found on the upper esophageal wall and pharynx without active bleeding. The patient refused to stay in the emergency room for further observation and left the hospital.
Foreign objects ingestion occurs more commonly in the pediatric population,, which peaks in children aged six months to six years . The ingestion of foreign bodies is rarely seen in adults, accounting for 20% of these emergencies, which generally accidental and commonly seen in the form of food (meat and bones) ingestion . Patients who purposely swallow a true foreign body (nonfood object) typically are younger and more often male; associated psychiatric illness and/or drug abuse are common  The patient in this case admitted the history of drug abuse and may had a little depression which caused him to draw out the venous indwelling needle and refuse further observation after awake from the general anesthesia. Clinical presentations after foreign bodies’ ingestion depends on types and location of foreign bodies. Yao et al.  revealed that the most frequent symptomatic complaint after foreign bodies’ ingestion was odynophagia (36.5%). Most of the ingested foreign bodies were located in the upper esophagus. Thirty-four patients did not complain of any symptoms after foreign body ingestion and were classified as asymptomatic patients in contrast to symptomatic patients ( = 192). Among them, foreign bodies were most commonly located in the stomach and duodenum when found (17/34; 50%). The foreign body of this patient was very large (18cm X 2cm) with two hooks on the ends, but it was not sharp and located in the stomach,which resulted in none of symptoms for more than six days after ingestion. Although preendoscopic series have shown that 80% or more of the ingested objects are likely to pass spontaneously, in approximately 20% of cases, foreign bodies may require endoscopic or surgical intervention . Judgment of the risks of aspiration, obstruction, or perforation determines the timing of endoscopy. Patients with esophageal obstruction, disk batteries and sharp-pointed objects in the esophagus require emergent endoscopy. Esophageal foreign objects that are not sharppointed or without complete obstruction and sharp-point objects or foreign body more than 6 cm in the stomach or duodenum need urgent endoscopy. In this case, the metal foreign object was too large to pass through the pylorus. There was only a little erosion on the surface of the gastric antrum without any significant ulcers or other complications. Because of the patient’s ignorance, the endoscopic procedure was achieved after nearly a week. There are many retrieval devices available, including rat-tooth and alligator forceps, polypectomy snares, polyp graspers, baskets, retrieval nets, magnetic probes, and friction-fit adaptors or banding caps . An overtube or a retractable latex-rubber condom-type protector hood is recommended to protect the esophageal mucosa from lacerations during retrieval of sharp or pointed objects [8,9]. The diameter of the huge spring was approximately 2 cm, which was more than the diameter of the endoscopic overtube (US endoscopy 16.7mm) . The Roth Net® maxi retriever is about 4 x 8cm, which is not large enough for this spring. Considering the size of the foreign body and risk of the lacerations, the patient was recommended to the surgery at first. But we attempted the endoscopy procedure under the family’s insistence and finally removed the huge spring without severe complications such as the esophagus or gastroesophageal junction injuries fortunately. In conclusion, it was lucky to retrieve this kind of unusual huge foreign object by endoscope. We propose this case to arouse further concern about conditions such as huge foreign bodies, how to be extracted more safely and less invasive.
