A Case of Eosinophilic Gastroenteritis with Small Bowel Perforation

Abstract

A 37-year-old man was admitted to our hospital due to abdominal pain. Abdominal computed tomography showed thickening of the small intestine and free air, suggesting perforation of the small intestine. Laparoscopic surgery was performed, and perforation of the small intestine was confirmed. However, it was necessary to search the abdominal cavity in detail, and laparotomy was performed. A stenosis of about 30 cm was found in the small intestine, and a perforation about the size of a pin hole was observed in the small intestine about 40 cm on the oral side from the stenosis. The stenosis site and perforation site were resected together, and a small intestine to small intestine anastomosis was performed. The postoperative pathological findings showed a group of eosinophilic gastroenteritis muscular lesions. There was no relapse after surgery with steroid therapy. Severe eosinophilic gastroenteritis that causes perforation of the small intestine is not cured even after excision of the lesion site, and steroid therapy is necessary to prevent relapse after surgery.
