The preoperative use of endoscopic ultrasound was evaluated in 74 patients with confirmed gastric cancer. It was used in diagnosing the depth of invasion in the gastric wall, the infiltration to the adjacent organs, and the involvement of the perigastric lymph nodes. Results were compared with histological findings in resected specimens. Accuracy in staging gastric cancer using the T grade of the 1987 TNM system was 81.1% (60 of 74 patients). Endoscopic ultrasound provided excellent results compared with computed tomography and conventional ultrasound, particularly in evaluating perigastric lymph node metastasis and direct infiltration to the adjacent organs. The success rate in detecting lymph node metastasis was 50% (11 of 22 patients); the accuracy in diagnosing direct infiltration to the adjacent organs was 60% (three of five patients). This technique is useful in diagnosing malignant invasion and lymph node metastasis of gastric carcinomas but requires further refinement for use in diagnosing the disease itself. Its preoperative use is recommended for establishing surgical and other treatment plans, as well as in predicting the prognosis of gastric cancer.
对74例确诊为胃癌的患者进行了术前内镜超声检查的评估。该检查用于诊断胃癌侵犯胃壁的深度、对相邻器官的浸润情况以及胃周淋巴结的受累情况。将结果与切除标本的组织学检查结果进行比较。采用1987年TNM系统的T分级对胃癌进行分期的准确率为81.1%（74例患者中的60例）。与计算机断层扫描和传统超声相比，内镜超声检查取得了优异的结果，尤其是在评估胃周淋巴结转移和对相邻器官的直接浸润方面。检测淋巴结转移的成功率为50%（22例患者中的11例）；诊断对相邻器官直接浸润的准确率为60%（5例患者中的3例）。该技术在诊断胃癌的恶性浸润和淋巴结转移方面很有用，但在诊断疾病本身方面还需要进一步完善。建议在术前使用该技术来制定手术和其他治疗方案，以及预测胃癌的预后。
