| pubmed-article:2676968 | pubmed:abstractText | Computed tomography (CT) of the esophagus, the stomach and the duodenum allows characterization of some lesions: lipomas, cysts and duplications, recent haematomas, vascular anomalies. CT is particularly used for the extramural staging of neoplasms: despite important limitations, CT may be useful as staging test to identify a subgroup of patients with definitive metastases or local invasion who therefore have unresectable tumors. CT is helpful for the staging of lymphomas. The importance of this staging classification is reflected in differences in treatment and prognosis. CT is also useful for the follow-up after treatment, the diagnosis of recurrence and postoperative complications. | lld:pubmed |
