4. Conclusion
 Bezoar formation: in normal and abnormal gastrointestinal
anatomy and physiology.
 Gastrectomy, diabetes mellitus and high intake of fibre: the
important risk factors
 PBZ: different locations, colors, sizes. Assocation with ulcer.
 Treatment with endoscopic “modified snares”: low cost,
safe and effective.
