Diagnosis and Treatment of Foreign Bodies Outside Pharynx and Esophagus Lumen

Study Overview
=================
Brief Summary
-----------------
Objective: To improve the success rate of the treatment of migrating foreign bodies in the upper aerodigestive tract. Methods: The medical records of inpatients conforming to the diagnosis of migrating foreign bodies between 2020 and 2025 were reviewed. Data regarding age, gender, time from onset to hospitalization, computed tomography (CT) and endoscopic scans, surgical procedures，and follow-up were collected.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Conventional surgery group<br>Conventional surgery with Preoperative foreign body localization | Procedure: exploratory surgery<br>* For foreign bodies in the retropharyngeal space or parapharyngeal space above the esophageal entrance, close to the laryngopharynx cavity with large operating space, suspension laryngoscopy is the first choice according to the principle of proximity. In all cases, a lateral cleft laryngoscope was used to expose the posterior or lateral wall of the laryngopharynx, and 30° endoscope or microscope was used according to the skills of the surgeon. For a foreign body below the esophageal entrance, the lateral cervical incision was the first choice due to the small operating space of oral exposure. The lateral cervical incision and other open surgical methods are used for foreign bodies below the entrance of the esophagus or in the submaxillary space or for the anterior cervical band muscle foreign bodies.<br>* Other names: lateral cervical incision surgery;|
| New surgery group<br>new surgery with Intraoperative localization of foreign body | Procedure: exploratory surgery<br>* For foreign bodies in the retropharyngeal space or parapharyngeal space above the esophageal entrance, close to the laryngopharynx cavity with large operating space, suspension laryngoscopy is the first choice according to the principle of proximity. In all cases, a lateral cleft laryngoscope was used to expose the posterior or lateral wall of the laryngopharynx, and 30° endoscope or microscope was used according to the skills of the surgeon.
