Abstract
The incidence of gastric cancer associated with esophageal cancer is notably high. In recent years, there has been an increase in patients with gastric conduit cancers due to early detection and radical treatment of esophageal cancer, leading to prolonged survival of the patients. Metachronous gastric cancer following esophagectomy sometimes can pose a clinical challenge for surgeons, while gastric tube reconstruction is a well-established procedure accompanying esophagectomy, treating gastric cancer within the gastric tube can be difficult in contrast. Surgical treatment of gastric tube cancers is often complex and life-threatening. Early detection of gastric tube cancer is crucial for improving prognosis as it allows for less invasive surgical interventions. However, no specific guidelines for detecting gastric tube cancer have been established. In this report, we present a case of gastric tube cancer in a patient that had Ivor-Lewis surgery 20 years ago for preinvasive adenocarcinoma of the thoracic esophagus against the background of Barrett's esophagus. Recommendations for earlier and more accurate diagnosis and treatment of this pathology are discussed.
