A 76-year-old man underwent esophagogastroduodenoscopy (EGD) in 2017, as surveillance after gastric endoscopic submucosal dissection (ESD). Examination revealed a post-ESD scar and a 4 mm sessile polyp in the gastric fundus, removed through cold forceps biopsy (Fig. 1). Persistent bleeding at the polypectomy site was successfully controlled by the placement of 2 endoclips (Resolution Clip, Boston Scientific Co., Marlborough, Massachusetts, USA) (Fig. 2). Histology study of the resected polyp identified hyperplasia. The following year a gastric metachronous lesion was detected and a second ESD was successfully performed. Endoscopic control in 2019 showed post-ESD scars and the continued presence of the 2 hemostatic endoclips at the polypectomy site (Fig. 3). Another surveillance EGD was recently carried out and revealed one hemostatic endoclip still in place, with no significant alterations of the surrounding mucosa (Fig. 4). Only one previous report has described a 2-year retention of a hemostatic clip in the duodenum, secondary to gastrointestinal bleeding.1 Most authors agree that the type of endoclip used is a determining factor for its prolonged retention at the application site.2,3 The incidental detection of retained endoclips does not modify their original indication.3,4
