Survey of Instruments and Techniques for Endoscopic Retrieval of Esophageal and Gastric Foreign Bodies in Cats and Dogs

Abstract

Esophageal and gastric foreign bodies (EFB and GFB) are a common occurrence in cats and dogs. The objective of this study is to evaluate the endoscopic instruments and techniques used for foreign body retrieval by internists or criticalists based on type and location of the foreign body. An online, anonymous survey was created using a commercial software. The survey was distributed to diplomates of the ACVIM (SAIM) and ACVECC through each college's listserv. Data obtained included specialty, years in practice, practice type, available instruments, and preferred instrument for various foreign bodies by location and type. Two hundred sixty-eight surveys were completed with 74% from private referral practice and 21% from academic practice. For EFB, laparoscopic or endoscopic grasping forceps were used most commonly. For GFB, grasping forceps or loop snares were used most commonly. Fifty percent of respondents reported attempting duodenal FB removal. In practices with limited financial resources, endoscopic grasping forceps and loop snares may be prioritized for purchase as these instruments may have the most application for foreign body retrieval from the esophagus and stomach.
