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.

Inclusion Criteria: -Consecutive patients who underwent dual-instrument endoscopic retrieval for upper gastrointestinal foreign bodies at our center during the study period. Exclusion Criteria: -Patients with incomplete clinical or procedural records. Patients lost to follow-up immediately after the procedure.
