A Novel Strategy for Endoscopic Dual-instrument Retrieval of Upper GI Foreign Body

We describe a single-center, retrospective case series (n = 10) for the utilization of dual instruments to extract foreign body at physiological narrowing. Foreign bodies that failed to remove with a single instrument or located in physiological narrowing into the duodenal bulb or descending duodenum were considered appropriate for this technique. Informed consent was obtained from all patients before the procedure.

Treatment and study plan

Primary outcomes

  1. Successful Endoscopic Foreign Body Removal Rate

    Time frame: 1 day

    Percentage of patients in whom the foreign body is completely removed using the dual-instrument endoscopic retrieval technique without the need for surgical intervention. Success will be assessed by direct endoscopic visualization and procedural records.

Secondary outcomes

  1. Procedure-Related Adverse Event Rate

    Time frame: 1 week

    Percentage of patients experiencing procedure-related adverse events, including mucosal injury, bleeding, perforation, aspiration, or infection. Adverse events will be assessed based on endoscopic findings, clinical evaluation, and post-procedural medical records.
