Article: Preoperative diagnosis of gastric tumors by three-dimensional multidetector row ct and double contrast barium meal study: correlation with surgical and histologic results.[show abstract] [hide abstract]
ABSTRACT: Recent three-dimensional multidetector row computed tomography (3D MDCT) can provide detailed images of a gastric tumor, including its general contour, location and depth. We therefore evaluated the efficacy of MDCT in the differential diagnosis and staging of gastric tumors in patients prepared for surgery. Seventy-nine patients with gastric tumors identified by gastric optical endoscopy were admitted for preoperative evaluation. All patients received double-contrast barium meal (DCBM) study and abdominal MDCT with 3D reconstruction before surgery. We compared the accuracy of MDCT with DCBM study in detecting and differentiating gastric tumors. In addition, the MDCT findings were correlated with surgical and pathologic results in gastric cancers for Borrmann type, T and N stages. Among the 79 patients with gastric tumors, there were 24 cases of early gastric cancer, 40 cases of advanced gastric cancer, 12 cases of gastrointestinal stromal tumor, and three cases of gastric lymphoma. Both MDCT and DCBM were very accurate in picking up the lesions (100%). The diagnostic accuracies of MDCT and DCBM were similar (94% vs. 96%) in differentiating mucosal and submucosal lesions as well as classification of Borrmann type in advanced gastric cancer (70% vs. 63%). In 64 patients with gastric cancers, there was good correlation between MDCT images and pathology in 73% of T staging and 69% of N staging. MDCT has a similar high accuracy in the preoperative diagnosis of different gastric tumors compared with DCBM and provides additional information including tumor depth, lymph node and hepatic metastasis. Therefore, MDCT may be used as a primary tool for preoperative tumor diagnosis and staging.Journal of the Formosan Medical Association 12/2007; 106(11):943-52. · 1.13 Impact Factor

ABSTRACT: We presented the X-ray and CT findings characteristic for gastric cancers of different localizations (localized in different parts of the stomach). Particularly, esophagogastric junction (EGJ) carcinomas and antral carcinomas are singled out, as two localizations of gastric cancer that we usually meet in everyday clinical and radiological practice, and which have completely different radiological presentation. Advanced carcinomas of esophago-gastric junction, whose incidence is on the rise, usually affect the distal segment of the esophagus, cardia, and proximal part of the stomach, in different proportions. Siewert's, and the Japanese classification of these tumors are listed. Due to the involvement of the distal esophagus, scanning region, besides the abdomen, should be expanded to the chest. Advanced cancer of the antral part of the stomach is presented by the X-ray as a fungating, infiltrative, or combined form, often capturing the entire wall circumference. Possible infiltration of the left liver, the body and neck of the pancreas, colon and anterior abdominal wall should be estimated by CT.Acta Chirurgica Iugoslavica. 01/2009;
