A Case of Esophageal Perforation of Ectopic Gastric Mucosa

Abstract

We present a case of ectopic gastric ulcer perforation of the esophagus. A 52-year-old man receiving medication for a duodenal ulcer experienced sudden epigastralgia and increased pain after serious vomiting. Based on highly suspicious for esophageal perforation, he was admitted. Barium study and computed tomography showed a perforation at the left side of the lower esophageal wall. Under a right thoracoabdominal approach, we conducted esophagectomy and esophagogastrostomy. Postoperatively, sepsis due to serious inflammation in the mediastinum occurred. He gradually recovered without anastomotic leakage or mediastinal abscess. In resected specimens, perforation of the ectopic gastric mucosa in the lower esophagus was found pathologically. No symptoms usually occur in ectopic gastric mucosa of the esophagus, and such lesions are found incidentally by endoscopy. We should thus be mindful of the risk of perforation and explain it to patients with such lesions.
