Summary
Foreign material, such as surgical sutures or cellulose, was found in 11.1% of common bile duct (CBD) stones. This study confirms foreign bodies can cause gallstones, even without prior surgery.
Area of Science:
- Gastroenterology
- Biliary tract disease
- Medical materials science
Background:
- Sporadic reports suggest foreign material can cause choledocholithiasis (gallstones in the bile duct).
- The role of foreign bodies in gallstone formation requires further investigation.
Purpose of the Study:
- To analyze the structure of gallstones and identify any foreign material present.
- To investigate the correlation between foreign material in gallstones and patient clinical data.
Main Methods:
- Gallstones were collected endoscopically from the common bile duct.
- X-ray powder diffraction was used for crystallographic analysis.
- Polarization microscopy was employed for morphological analysis of foreign material.
Main Results:
- Foreign material was detected in 11.1% of common bile duct stones from 54 patients.
- Surgical suturing material was found in 4 patients with prior cholecystectomy.
- Cellulose and an unidentified fiber were found in 2 patients without prior surgery.
Conclusions:
- Foreign material can contribute to the formation of biliary duct stones.
- This study demonstrates that foreign bodies can cause gallstones even in patients without previous pancreatobiliary surgery.
