Abstract
A 80-year-old man visited our hospital complaining of epigastric pain and vomiting lasting for a week. The upper gastrointestinal endoscopy revealed a gold bezoar about 5 cm in diameter at the greater curvature of the upper body of the stomach associated with multiple ulcers (H1 stage) on the lesser curvature of the antrum. We attempted to remove the bezoar endoscopically using a retrieval net (Model 0071182 USE Group, Olympus Ltd. Tokyo) with success. The bezoar was 5×4×3 cm in size and 7.72g in weight. Compornent analysis with infrared absorption spectrum of the sample detected tannic acid, giving a diagnosis of persimmon bezoar.
As gastric bezoar has been reported to be a cause of ulcer due to mechanical stimulation or intestinal obstruction, removal of bezoar should be considered on diagnosis regardless of symptoms. Endoscopic approach using a retrieval net is a safe and effective modality.
