The case of endoscopic extraction of a foreign body of the gastric antral wall using full-thickness resection

Abstract

Most of the swallowed foreign bodies pass through the gastrointenstinal tract (GIT) and only 1% of them are required surgery. Many authors have reported different cases of a foreign body migration deep into the layer of the gastrointestinal tract and their successful subsequent surgical treatment. However, there are some limited reports about the extraction of the embedded foreign bodies, when endoscopic techniques, such as endoscopic submucosal dissection, are used. We present the case of a 70-years old patient who was performed full-thickness resection of a duodenal neuroendocrine tumor. According to upper endoscopy, the submucosal gastric antral tumor was suspected. During the preoperative examination, esophagogastroduodenoscopy, endosonography and computed tomography were performed, but the nature of the formation was not determined. During the full-thickness resection, the embedded foreign body (a fish-bone) with the fistula around it was revealed and successfully extracted. This case demonstrates a rare pathological situation – the foreign body of the gastric wall, as well as the efficiency of flexible intraluminal endoscopy to extract it.
