从临床表现无法鉴别胃癌和淋巴瘤,临床、放射学、内镜和活检检查有时难以在术前作出胃淋巴瘤的正确诊断。内镜检查仅能观察胃腔表面,而内镜腔内超声扫描(EUS)则可显示肿瘤的深度、局部浸润、肿瘤与邻近器官的关系以及淋巴结转移,这些资料皆有助于胃癌和淋巴瘤的诊断和分期。作者对86例内镜检查疑有胃恶性病变者作前瞻性研究。在内镜检查时均作活检,随后再作EUS检查。全部病例进行剖腹探查,作出最后的诊断、分期和治疗,将EUS结果与活检和切除标本的组织学发现进行对比。
Since clinical manifestations cannot distinguish between gastric cancer and lymphoma, clinical, radiological, endoscopic, and biopsy examinations sometimes make it difficult to correctly diagnose gastric lymphoma before surgery. Endoscopy can only observe the surface of the gastric cavity, and endoscopic ultrasound scanning (EUS) can show the depth of the tumor, local infiltration, the relationship between the tumor and adjacent organs, and lymph node metastasis. These data are helpful for gastric cancer and lymphoma. The diagnosis and staging. The authors conducted a prospective study of 86 patients with suspected malignant gastric lesions. Biopsy was performed during endoscopy, followed by EUS. All cases were examined by laparotomy, and the final diagnosis, staging, and treatment were performed. The EUS results were compared with the histological findings of biopsy and resected specimens.
