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.

In this study, we retrospectively examined the records of 10 patients who underwent endoscopic foreign body extraction at Zhongshan Hospital, Fudan University between January 2018 and January 2026. All patients initially presented to the emergency department and underwent an initial single-instrument endoscopic retrieval attempt. When single-instrument retrieval was unsuccessful or unstable, a dual-instrument endoscopic retrieval technique was subsequently applied. All procedures were performed by a single experienced therapeutic endoscopist.
