胃恶性淋巴瘤临床特点及内镜下表现

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20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。

The clinical characteristics and endoscopic shows of gastric malignant lymphoma

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.
