Ultrasound-guided endoscopic retrieval of a deeply embedded cervical fish bone after failed open exploration: A minimally invasive salvage technique

Clinical management of cervical fish bone foreign bodies faces difficulties including missed diagnosis, invasive exploration, and high complication risks. Deeply embedded foreign bodies invisible under endoscopy often elude open surgery, leading to persistent symptoms, fistula, and infection, while conventional imaging has limitations in real-time and soft-tissue localization.

Zhangfeng Wang et al reported a case in ENT Discovery describing a minimally invasive salvage technique for refractory cervical fish bones. They used ultrasound-guided endoscopic retrieval after failed open exploration and assessed its safety and efficacy. The 27-mm foreign body was precisely located and successfully removed, with symptom relief and complete fistula healing. This method provides real-time navigation, no radiation, minimal trauma, and higher accuracy.

This study advances otorhinolaryngology by establishing a safe rescue strategy for difficult foreign bodies. It provides a practical reference for treating deeply embedded pharyngeal foreign bodies and supports the development of more minimally invasive and precise clinical protocols. The work entitled “Ultrasound-Guided Endoscopic Retrieval of a Deeply Embedded Cervical Fish Bone After Failed Open Exploration: A Minimally Invasive Salvage Technique” was published on ENT Discovery (published on Apr. 01, 2026). Reference: Hang Li, Lin Chen, Wenbin Lei, Zhangfeng Wang.
