Diseases of the gastrointestinal tract may result in radiographic changes in the thorax. An abnormal chest radiographic finding is often the initial clue to the diagnosis of gastrointestinal disease. This article presents the commonly recognized and some unusual thoracic manifestations of significant primary esophageal diseases including achalasia, diverticula, carcinoma, duplication cysts, varices, esophageal perforation, and postoperative changes. Intraabdominal gastrointestinal processes such as pancreatitis or pseudocysts, gastric and colonic abnormalities, pneumoperitoneum, liver abnormalities, intraabdominal abscesses, and diaphragmatic hernias, which are frequently associated with intrathoracic abnormalities, are also reviewed. Awareness of changes on the chest radiograph produced by gastrointestinal disease allows prompt diagnosis and facilitates the appropriate confirmatory diagnostic study, such as esophagography or computed tomography.
胃肠道疾病可能导致胸部的影像学改变。胸部X线检查异常往往是胃肠道疾病诊断的最初线索。本文介绍了重要原发性食管疾病（包括贲门失弛缓症、憩室、癌、重复囊肿、静脉曲张、食管穿孔及术后改变）常见的以及一些不常见的胸部表现。还对常与胸内异常相关的腹内胃肠道病变（如胰腺炎或假性囊肿、胃和结肠异常、气腹、肝脏异常、腹内脓肿及膈疝）进行了综述。了解胃肠道疾病引起的胸部X线改变有助于及时诊断，并有利于进行适当的确诊性诊断检查，如食管造影或计算机断层扫描。
