摘要:

［目的］探讨胃黏膜相关淋巴组织（mucosa-associated lymphoid tissue，MALT）淋巴瘤内镜下表现特征，以提高早期诊断水平。［方法］总结40例经内镜及手术病理确诊的胃MALT淋巴瘤患者的内镜下表现资料。［结果］病变多位于胃窦部、胃体部，累及多部位者25例（62.5%），表现为溃疡型、隆起型、浸润型及糜烂型损害，以病变范围较大、病变形态多样、多灶性损害为特征。［结论］胃MALT淋巴瘤内镜下表现多样，内镜下深凿取材，结合超声内镜、免疫组化检查可提高内镜诊断率。

Abstract:

［Objective］To improve the accuracy of early diagnosis, the endoscopic features of gastric mucosa-associated lymphoid tissue (MALT) lymphoma were investigated. ［Methods］The endoscopic features of 40 cases diagnosed by endoscopy and surgical pathology in patients with gastric MALT lymphoma were reviewed and analyzed retrospectively. ［Results］The lesions were mainly localized in the gastric antrum and body. Twenty-five (62.5%) of the patients showed multiple site lesions, which were ulcer type, bulge type, invasive type and erosive, with the characterizations of larger, various shapes and multifocal lesions.［Conclusion］The endoscopic features of gastric MALT lymphoma are not specific. Endoscopic deep biopsy pathology combined with endoscopic ultrasound and immunohistochemistry examination can further improve the accuracy of diagnosis.
