Bezoars, foreign material accumulations in the stomach, are increasingly diagnosed due to gastrointestinal surgery. Endoscopy is key for identification and removal, with prevention strategies crucial post-treatment.

Area of Science:

  • Gastroenterology
  • Surgical Pathology

Background:

  • Bezoars are gastric foreign body concretions with a long history in humans and animals.
  • Their incidence in humans has risen, often linked to gastrointestinal surgical interventions.
  • Composed of diverse materials, bezoars can cause significant gastrointestinal pathology.

Purpose of the Study:

  • To review the diagnosis, classification, and management of bezoars.
  • To highlight the role of endoscopy in bezoar identification and treatment.
  • To emphasize the importance of preventing bezoar recurrence.

Main Methods:

  • Literature review on bezoar formation, clinical presentation, and diagnostic modalities.
  • Analysis of radiological and endoscopic findings in bezoar cases.
  • Discussion of therapeutic strategies including endoscopic removal and surgical intervention.

Main Results:

  • Radiology can suggest bezoars, but endoscopy offers definitive identification and classification.
  • Endoscopic removal is feasible for many bezoars, while others necessitate surgery.
  • Recurrence prevention is a critical aspect of patient management post-bezoar removal.

Conclusions:

  • Accurate recognition and classification of bezoars are essential for appropriate therapeutic decisions.
  • Endoscopic techniques are paramount for diagnosing and treating bezoars.
  • Long-term management should focus on preventing bezoar recurrence.
