Abstract: | To detect early esophageal cancer effectively, it is important to select high-risk groups. Because we often see early esophageal cancer after gastrectomy for gastric cancer, we investigated 11 early esophageal cancers treated endoscopically in 7 patients who had undergone gastrectomy for gastric cancer. Their average age was 70.8 ± 5.2 years. Median interval between previous gastrectomy and the diagnosis of esophageal cancer was 10 years. Endoscopic examination revealed mild bile reflux into the remnant stomach and esophagitis, but there was no case of Barrett's esophagus. Histological types were all squamous cell carcinoma. Although it has been reported that cancer development is most frequent in the lower esophagus after gastrectomy, we noticed that the majority of these were located in the middle thoracic esophagus (6/11, 55%), similar to general esophageal cancer. As all cases were detected by a regular checkup, it is important to follow up patients after gastrectomy for gastric cancer. |
