Bezoars are relatively uncommon concretions of undigested or partially digested material in the gastrointestinal tract, mostly in the stomach. Their prevalence varies among geographic locations and ethnic groups with different dietary habits. They are classified according to their predominant component. Main predispositional factors to bezoar formation are altered anatomy and disordered motility of the gastrointestinal tract. Patients remain asymptomatic for a long time and symptoms develop as these accumulations adhere to mucosa, causing ulceration and bleeding, or increase in size to the point of obstruction or perforation and peritonitis. Endoscopy and computed tomography play major role in timely diagnosis; otherwise, the diagnosis can be made intraoperatively and it is challenging. The optimal treatment strategy remains under question and differs for each patient, especially for complicated cases. The available treatment options for bezoars include chemical dissolution for elective cases, and removal by endoscopy or surgery for elective or emergent cases. Better understanding of the etiology, epidemiology and clinical manifestation of each type of bezoar will facilitate prompt diagnosis and management, avoiding significant morbidity and mortality. Here, we briefly review relevant basic knowledge and research.
