Safe retrieval of gastrointestinal foreign bodies using the novel endoscopic attachment with a flower-shaped design

Safe retrieval of gastrointestinal foreign bodies using the novel endoscopic attachment with a flower-shaped design When performing the endoscopic retrieval of foreign bodies from the gastrointestinal tract, attaching a hood to the distal tip of the endoscope is necessary to ensure safe removal 123. However, if a foreign body cannot be accommodated within the hood, the risk of gastrointestinal injury exists. Herein, we report a safe retrieval technique using a novel endoscopic distal attachment specifically designed for foreign body retrieval (Endo-Flower; Fujifilm Medical Corporation, Tokyo, Japan). Case 1 (Fig. 1): A 75-year-old woman accidentally ingested a press-through package (PTP) sheet. Case 2 (Fig. 2): A 57-year-old woman accidentally ingested a fish-bone. Case 3 (Fig. 3): A 92-year-old woman had accidentally ingested a denture. In all cases, the foreign body was successfully retrieved using an endoscope equipped with a novel attachment, without causing any gastrointestinal injury (Video 1). The novel attachment is a dedicated foreign-body retrieval device composed of five silicone flaps in a flower-shaped design. This attachment has a total length of 20 mm and consists of five 20 30 mm flaps (Fig. 4). During endoscope insertion, the flaps are folded opposite to the direction of scope advancement to avoid obstructing the visual field. Although esophageal inversion of the flaps is sometimes possible, it was difficult in the present three cases; therefore, they were inverted in the stomach to envelop the foreign body (Fig. 5). This attachment may be a safe and effective option for foreign body retrievals.
