Giant gastric bezoar removal from the stomach using combined dual knife–electric snare treatment: a case report

Gastric bezoars are foreign bodies that occur when certain drugs or foods aggregate in the stomach. They cannot be digested and most are unable to pass through the pylorus. Here, we describe a giant hard gastric bezoar that was removed by using combined dual knife–electric snare treatment. This strategy has rarely been reported and can eliminate the need for surgery. The patient exhibited a giant hard gastric bezoar and reported a habit of eating persimmons. A giant persimmon bezoar was treated using a combined dual knife–electric snare approach, without any complications. Follow-up endoscopy revealed that the bezoar had been successfully removed. This report also provides a summary of the diagnostic and therapeutic courses of gastric bezoars.
