Abstract:
A 65-year-old man was admitted under emergency to our hospital because of abdominal pain. His current medication history did not include steroids or nonsteroidal antiinflammatory drugs. He had taken an eradication agent for Helicobacter pylori, and his serum was negative for H. pylori IgG antibody. Abdominal computed tomography indicated gastric perforation;therefore, emergency surgery was performed. Two weeks later, esophagogastroduodenoscopy revealed a gastric ulcer on the lesser curvature of the gastric angle and bezoars. The gastric perforation was thought to be caused by the bezoars. The bezoars were successfully treated with endoscopic therapy using Coca-Cola®. The bezoars included over 98% tannin, and the patient had frequently consumed chestnuts. We thus diagnosed a rare case of gastric perforation caused by chestnut bezoars.

Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
