胃恶性淋巴瘤临床特点及内镜下表现

The clinical characteristics and endoscopic shows of gastric malignant lymphoma

目的 :探讨原发性胃恶性淋巴瘤的临床特点及内镜下表现 ,以提高诊断水平。方法 :对2 0例胃原发性恶性淋巴瘤的临床资料及内镜下表现进行回顾分析。结果 :胃恶性淋巴瘤的临床表现多样 ,主要为上腹胀痛、消瘦、纳差、黑便、反酸、呕吐、发热。内镜下表现病变多累积胃体 ,主要形态包括溃疡 ,肿块 ,浸润病变 ,胃体黏膜粗大或结节。本组病理内镜活检确诊率高达 80 %。内镜下多次多点活检 ,深凿活检及黏膜大活检可提高本病的早期诊断率。结论 :内镜为诊断胃恶性淋巴瘤的有效手段。

Objective: To improve the diagnostic levels of primary gastric malignant lymphoma by discussing its clinical characteristics and endoscopic shows.Methods: The data of 20 patients with gastric malignant lymphoma was reviewed. Results: The clinical symptom of gastric malignant lymphoma was multimophic, including stomachache, marasmus, inappetance,black dejecta, vomit and fever. Gastroscopy revealed that in most patients the body of stomach was involved by the primary gastric malignant lymphoma. The major lesion of the stomach body consisted of ulceration, tumour, infiltration, incrassation or node in the mucosa. Positive findings by biopsies attained 80%. The percentage rose up if more biopsies taken from multiple sites, deep bites and mucosal strips. Conclusion: Gastroscopy remains to be a valuable means in the diagnosis of gastric malignant lymphoma.
