A swallowed clamshell lodged in the duodenum mimicked a biliary stone. Endoscopic retrieval using a Dormia Basket was successful, allowing for safe patient discharge. This case highlights a rare gastrointestinal foreign body presentation.
Area of Science:
- Gastroenterology
- Endoscopy
- Radiology
Background:
- Ingested foreign bodies typically pass spontaneously but sharp or large objects necessitate removal.
- Complications from retained foreign bodies can be severe.
Observation:
- A 60-year-old man presented after swallowing a clamshell.
- The clamshell traversed the pylorus and became lodged in the duodenum.
- Radiological imaging suggested a biliary stone.
Findings:
- Endoscopic retrograde cholangiopancreatography (ERCP) was considered but not performed.
- A Dormia Basket was used for endoscopic retrieval of the clamshell.
- The clamshell was successfully removed without complications.
Implications:
- This case demonstrates a rare cause of duodenal obstruction.
- Endoscopic retrieval is a safe and effective method for removing large duodenal foreign bodies.
- Accurate radiological interpretation is crucial for diagnosing unusual foreign body presentations.
