Endoscopic Removal of Large Sharp-edged Foreign Bodies in the Gastrointestinal Tract Using an Innovative Modification of the Overtube.

ABSTRACT

Foreign body ingestion is commonly encountered in clinical practice. According to standard guidelines, urgent therapeutic endoscopy should be performed in cases involving sharp objects to prevent complications. Although several extraction methods are available, few cases may still pose a therapeutic challenge. This report describes a novel endoscopic technique utilizing modification of the standard overtube to facilitate the removal of a large razor blade. This technique offers a minimally invasive approach for rapid retrieval of large sharp-edged foreign bodies, obviating the need for a surgical exploration. Additionally, this article compares various imaging modalities for prompt detection of gastrointestinal foreign bodies to avoid unnecessary delays in endoscopic intervention.
