目的总结胃粘膜相关淋巴组织淋巴瘤(MALT淋巴瘤)的内镜特征。方法对19例胃MALT淋巴瘤患者的临床资料进行回顾分析。结果胃MALT淋巴瘤的内镜下表现呈多样性改变 ,病变累及胃体最多(78.9 %) ,主要病变形态包括溃疡(63.2 %)、肿块(15.8 %)、浸润病变(15.8 %)及糜烂(5.3 %)。大多数患者 (73.7 % )有较典型的恶性征象 ,但少数可无典型恶性征象 ,甚至仅表现为一般的炎症及糜烂。本组病例内镜活检确诊率高达84.2 % ,内镜下多次多点活检 ,深凿活检及粘膜切除法(EMR)活检可提高本病的早期诊断率。结论内镜为诊断胃MALT淋巴瘤的有效手段
Objective To summarize the endoscopic features of gastric mucosa-associated lymphoid tissue lymphoma (MALT lymphoma). Methods The clinical data of 19 patients with gastric MALT lymphoma were retrospectively analyzed. Results The endoscopic appearance of gastric MALT lymphoma showed a diversity of changes. The lesions involved most of the gastric body (78.9 %). The main lesions included ulcers (63.2 %), tumors (15.8 %), invasive lesions (15.8 %) and erosion ( 5.3%). The majority of patients (73.7%) had more typical malignant signs, but few had no typical signs of malignancy or even showed only general inflammation and erosion. The rate of diagnosis of endoscopic biopsy in this group was as high as 84.2%. Multiple biopsies were performed under endoscopy. Deep-seated biopsy and mucosal resection (EMR) biopsy can improve the early diagnosis rate of this disease. Conclusion Endoscopy is an effective method to diagnose gastric MALT lymphoma
