Dual snare endoscopic extraction of a gastric foreign body using a dual-channel endoscope

Abstract

Foreign body ingestion, though rare, poses significant health risks, with 10%–20% of cases requiring endoscopic intervention. This article presents a novel case of a 16-year-old female who ingested a cigarette lighter, leading to abdominal pain and radiographic confirmation of a gastric foreign body. Initial attempts at retrieval using grasping forceps and snares were unsuccessful due to the object's size and shape, risking potential complications. We employed a dual-channel endoscope utilizing a push-pull technique with two snares, one capturing the blunt end and the other the sharp edge of the lighter. This method facilitated safe extraction through the gastroesophageal junction without causing trauma. This case highlights the efficacy of dual snares in the endoscopic retrieval of challenging foreign bodies and emphasizes the importance of appropriate techniques in preventing complications during such procedures.
