Summary
A new U-wire technique safely removes ring-type foreign bodies from the gastrointestinal tract. This endoscopic method offers a straightforward solution for challenging foreign body removal cases.
Area of Science:
- Gastroenterology
- Endoscopic procedures
- Medical device innovation
Background:
- Foreign body ingestion is prevalent in specific populations, including pediatric, edentulous, psychiatric, and incarcerated individuals.
- Approximately 20% of ingested foreign bodies require intervention beyond spontaneous passage.
- Flexible endoscopy is the standard for non-spontaneously passing foreign body removal.
Observation:
- A novel endoscopic technique was developed for removing ring-type or "closed loop" foreign bodies.
- The technique involves a nasogastric tube, guidewire, and grasping forceps to create a "U" shape with the guidewire.
- This maneuver facilitates the safe removal of the foreign body, endoscope, and nasogastric tube.
Findings:
- The described U-wire technique proved effective for endoscopic foreign body removal.
- The procedure was easy to perform and resulted in successful removal without complications.
Implications:
- The U-wire technique provides a safe and readily applicable method for removing ring-type foreign bodies.
- This innovation enhances the endoscopic management of gastrointestinal foreign bodies.
- The technique may reduce procedure time and patient morbidity for specific foreign body types.
