An observational study in Foreign Body Ingestion, sponsored by Shanghai Zhongshan Hospital. Active, not recruiting at 1 site in China. Per ClinicalTrials.gov, last updated 2026-08-05.
Sponsored by Shanghai Zhongshan Hospital · Observational
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.
29 studies on the registry are indexed under Foreign Bodies; 8 are open to participants now.
This study's enrollment of 10 is below the median of 100 across 19 observational studies indexed under Foreign Bodies.

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.

-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.
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.
Time frame: 1 day
Procedure-Related Adverse Event Rate
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.
Time frame: 1 week
Plan to share: No
