十二指肠降部黏膜下层隆起性病变17例临床分析

Clinical feature analysis of submucosal protrude at descending duodenum

目的探讨十二指肠降部黏膜下层隆起性病变的临床、内镜超声及病理特点。方法对17例十二指肠降部黏膜下层隆起性病变采用Olympus GIF H260型胃镜及Olympus UM-25R型及UM-3R型微探头超声胃镜确定病变层次、范围、超声特点后,17例均行内镜下"全瘤"活检术及套扎术加部分活检术。超声频率为:20MHz,高频电发生器为:YH300A。结果十二指肠降部黏膜下层隆起性病变以降部外侧壁及乳头旁多见,组织病理学结果示:脂肪瘤5例,十二指肠腺腺瘤4例,慢性炎性增生3例,神经节细胞性副神经节瘤2例,淋巴管瘤1例,错构瘤1例,囊肿1例。结论十二指肠隆起性病变以脂肪瘤和腺瘤多见,其次为炎性增生等。

[ Objective ] To evaluate the clinical features of endoscopic, uhrasonograph, and pathological features of submucosal protrude at descending duodenum. [Methods] 17 patients with submucosal protrude at descending duodenum all underwent endoscopic ＂all tumor ＂biopsy and ligation plus part of the biopsy after been confirmed the depth, range and ultrasound feature of lesion. The supersonic frequency is 20MHz, and the electrosurgieal generator is YH300A. [ Results ] In endoscope, submueosal protrude at descending duodenum are more common in paries lat- eralis and papilla. Among these 17 cases, 5 were lipoma, 4 were brunner adenoma, 3 were chronic inflammatory proliferation, 2 were ganglion cellularity vice-ganglioma, 1 was lymphangioma, 1 was hamartoma and 1 was cyst. [ Conclusion ] Lipoma and brunner adenoma was the leading cause of submucosal protrude at descending duode- num, which was followed by chronic inflammatory proliferation and so on.
