Two hundred and fifty four consecutive patients with gastric adenocarcinoma who underwent surgery were preoperatively evaluated with endoscopic ultrasonography (EUS). The results were compared with the post-operative histo-pathological staging. EUS was correct in determining the T and N stage in 83% and 66%, respectively. Although EUS was accurate in determining the absence of lymph node metastases (accuracy in stage N0: 93%), it was not reliable in determining stages N1 and N2 (64% and 52%, respectively). Since 88% of all T3 and T4 tumors had lymph node metastases, the concomitant T stage may be an important criterion for assessing the nature of endosonographically visualized lymph nodes. The actual R0-resection rate (78%) was almost identical to the rate predicted preoperatively by EUS (81%). We therefore consider EUS a valuable pretherapeutic procedure in patients with gastric carcinoma.
对254例接受手术治疗的胃腺癌患者术前进行了内镜超声检查（EUS）评估。将结果与术后组织病理学分期进行比较。EUS在确定T分期和N分期方面的正确率分别为83%和66%。尽管EUS在确定无淋巴结转移方面准确（N0期准确率：93%），但在确定N1和N2期时并不可靠（分别为64%和52%）。由于所有T3和T4肿瘤中有88%发生了淋巴结转移，因此伴随的T分期可能是评估内镜超声显示的淋巴结性质的重要标准。实际R0切除率（78%）与EUS术前预测的率（81%）几乎相同。因此，我们认为EUS对胃癌患者是一种有价值的治疗前检查方法。
