Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

• Successful Endoscopic Foreign Body Removal Rate

  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.

  1 day

Secondary Outcomes (1)

• Procedure-Related Adverse Event Rate

  1 week

Study Arms (1)

dual-instrument

Eligibility Criteria

• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

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.

You may qualify if:

• Consecutive patients who underwent dual-instrument endoscopic retrieval for upper gastrointestinal foreign bodies at our center during the study period.

You may not qualify if:

• Patients with incomplete clinical or procedural records. Patients lost to follow-up immediately after the procedure.
