Summary

This study tests a new endoscopic method that uses two instruments at once to remove foreign bodies (like swallowed objects) stuck in the upper digestive tract. The technique is for cases where a single tool fails or the object is lodged in a narrow area. Researchers reviewed records of 10 patients who had this procedure to see how often it successfully removes the object without needing surgery.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
endoscopic dual-instrument retrieval technique
What this could lead to
If successful, this technique could offer a less invasive way to remove stuck swallowed objects, potentially reducing the need for surgery.
What could go wrong
This is a very small study (10 people) looking back at past cases, so results may not apply to everyone. Risks include injury, bleeding, or infection from the procedure.

Who is studied

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.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)
