Abstract

Endoscopic ultrasonography (EUS) was performed in 82 patients with primary gastric lymphoma. EUS correctly diagnosed lymphoma in 76/82 patients, with a sensitivity of 93%. Positive predictability was 91%, specificity 98%, and negative predictability 98%. Diagnostic accuracy was 97%. In the evaluation of lymphoma, depth invasion EUS was correct in 87% of cases. EUS disclosed metastatic perigastric lymph nodes in 15/27 patients, with a sensitivity of 56%. Positive predictability was 100%, specificity 100%, and negative predictability 82%. Diagnostic accuracy was 85%. Differential diagnosis with EUS among lymphoma, linitis plastic and Ménétrier's disease was difficult. Large particle biopsy must be considered when EUS diagnosis of these diseases remains uncertain.

摘要

对82例原发性胃淋巴瘤患者进行了内镜超声检查（EUS）。EUS在82例患者中的76例正确诊断出淋巴瘤，敏感性为93%。阳性预测值为91%，特异性为98%，阴性预测值为98%。诊断准确率为97%。在淋巴瘤评估中，EUS对深度浸润的判断在87%的病例中是正确的。EUS在27例患者中的15例发现胃周转移性淋巴结，敏感性为56%。阳性预测值为100%，特异性为100%，阴性预测值为82%。诊断准确率为85%。EUS对淋巴瘤、皮革胃和门脉性胃病进行鉴别诊断很困难。当EUS对这些疾病的诊断仍不确定时，必须考虑进行大颗粒活检。
