64 patients with histologically proven gastric carcinoma were investigated by endosonography (EUS), computed tomography (CT) and conventional transcutaneous sonography (US). In 50 patients a resection of the stomach was performed and the histological findings were compared with the results of preoperative staging. In all cases EUS was successful in demonstrating the tumour. With CT tumour visualisation was possible in 17 (35.4%), with US in 7 (14.6%) cases. The pT-stage was correctly determined preoperatively by EUS in 40 (81.6%) with CT and US in only 12 (25%) and 4 (8.3%) patients, respectively. The staging accuracy of EUS amounted to 80% in T1-, 81% in T2-, 100% in T3-, and 67% in T4-stage. The sensitivity in demonstrating lymph node metastases was 81.3% for EUS, 25.8% for CT and 9.7% for US. The specificity in this regard was 72.2% for EUS, 83.3% for CT and 100% for EUS. The overall accuracy for determination of pN-stage was 78% for EUS, 47.9% for CT and 41.7% for US. EUS is clearly superior to CT and US in the locoregional TN-staging of gastric carcinoma.
对64例经组织学证实的胃癌患者进行了内镜超声检查（EUS）、计算机断层扫描（CT）和传统经皮超声检查（US）。50例患者进行了胃切除术，并将组织学检查结果与术前分期结果进行比较。在所有病例中，EUS均成功显示肿瘤。CT能显示肿瘤的有17例（35.4%），US能显示肿瘤的有7例（14.6%）。EUS术前正确确定pT分期的有40例（81.6%），CT为12例（25%），US仅为4例（8.3%）。EUS在T1期的分期准确率为80%，T2期为81%，T3期为100%，T4期为67%。EUS显示淋巴结转移的敏感性为81.3%，CT为25.8%，US为9.7%。在这方面，EUS的特异性为72.2%，CT为83.3%，US为100%。EUS确定pN分期的总体准确率为78%，CT为47.9%，US为41.7%。在胃癌的局部区域TN分期方面，EUS明显优于CT和US。
