肺癌肺切除後に発症した急性壊死性食道炎

Acute Necrotizing Esophagitis Occurred after Lung Resection for Lung Cancer

急性壊死性食道炎は，食道粘膜が黒色に色調変化をきたし黒色食道と呼ばれる．肺癌手術後に急性壊死性食道炎を発症した症例を経験したので文献的考察を加えて報告する．

The patient was a 78-year-old man who had undergone left lung segmentectomy （S6） with lymph node dissection for lung adenocarcinoma. One year and 5 months later, lung partial resection was performed for the lung cancer recurrence and the hematemesis was noted on the next day of surgery. Upper gastrointestinal endoscopy revealed extensive black necrosis on the mucosa of the esophagus, which was diagnosed as acute necrotizing esophagitis. To treat the bleeding, the exposed esophageal vessels were clipped via endoscopy several times. The endoscopy on the 64th post-operative day showed the mucosa recovered and he could be discharged on the 85th day. The exact etiology of acute necrotizing esophagitis is unknown in most cases.
