Summary
This study introduces the bezotome and bezotriptor, novel endoscopic tools for fragmenting large, hard bezoars. These devices effectively treat gastric and esophageal bezoars, offering a new solution for difficult cases.
Area of Science:
- Gastroenterology
- Endoscopic Surgery
Background:
- Bezoars, particularly large and solid ones, pose challenges for endoscopic removal.
- Previous endoscopic methods like water jet, forceps, snare, and basket have limitations for huge bezoars.
Purpose of the Study:
- To evaluate the efficacy of a modified needle-knife (bezotome) and a modified mechanical lithotriptor (bezotriptor) for fragmenting huge, solid gastric and esophageal bezoars.
Main Methods:
- The study included 15 patients with 18 bezoars treated endoscopically over 14 months.
- A modified needle-knife (bezotome) was used for trichobezoars, and a modified mechanical lithotriptor (bezotriptor) for diospyrobezoars.
Main Results:
- All 18 bezoars, ranging from 4x3x3 cm to 10x8x8 cm, were successfully fragmented.
- Complete clearance of the upper digestive tract was achieved within three days post-treatment.
- No complications were reported during the procedures.
Conclusions:
- The bezotome and bezotriptor are effective endoscopic instruments for disintegrating large, hard bezoars.
- These devices facilitate complete clearance of the upper digestive tract, offering a safe and efficient treatment option.
