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.

Ivor-Lewis 食管腺癌食管切除术后胃癌：病例报告和文献综述。

与食道癌相关的胃癌发病率特别高。近年来，由于食管癌的早期发现和根治治疗，胃导管癌患者有所增加，从而延长了患者的生存期。食管切除术后的异时性胃癌有时会给外科医生带来临床挑战，而胃管重建是食管切除术的成熟手术，相比之下，治疗胃管内的胃癌可能很困难。胃管癌的手术治疗通常很复杂并且危及生命。胃管癌的早期发现对于改善预后至关重要，因为它可以进行微创手术干预。然而，尚未制定检测胃癌的具体指南。在本报告中，我们介绍了一名胃管癌患者，该患者 20 年前因胸段食管浸润前腺癌接受了 Ivor-Lewis 手术，背景为 Barrett 食管。讨论了对该病理学进行更早、更准确诊断和治疗的建议。
