In this retrospective study, the aim was to determine the clinical findings and procedural success factors influencing the outcome of endoscopic removal of foreign bodies from the stomach in 24 cats that were confirmed radiographically that had been ingested penetrating and sharp sewing needles and were presented to the Surgery Department of Dicle University Faculty of Veterinary Medicine between 2020 and 2024. Parameters evaluated included operator experience, presence of gastric content, presence or absence of thread attached to the needle, duration of the endoscopic procedure, and the time interval between ingestion and intervention, in relation to procedural success and complications. Endoscopic retrieval of the needle was successful in 18 out of 24 cases (75%), while the combined success rate of both endoscopic and surgical interventions resulted in 23 out of 24 cats (95.8%) being discharged in good health. The success rate of endoscopic procedures was significantly higher (p<0.05) and the procedure duration was shorter in cases without gastric content. In all unsuccessful cases, gastric content was present, which was observed to obscure the field of vision and complicate the procedure. Minor complications included mild gastric mucosal hyperemia and superficial mucosal bleeding observed during endoscopy in some cases. Needle migration was not detected in any of the cases. Based on these findings, although it is well known that sharp and penetrating foreign bodies such as sewing needles pose a risk of gastrointestinal migration and require emergency intervention, we suggest that performing serial radiographs and monitoring for gastric content evacuation may significantly improve success rates of endoscopic removal. Therefore, we believe that rapid diagnosis, proper patient preparation, and well-timed intervention are crucial in the management of such foreign bodies in cats. Furthermore, clarifying the localization through serial radiography and allowing time for gastric content evacuation may reduce complication risks and make the treatment process safer.
