Jumbo biopsy is useful for the diagnosis of colonic prolapsing mucosal polyps with diverticulosis

我们这里在 S 字形的冒号与憩室形成报导多重 prolapsing 粘膜息肉的一个案例。因为流血腹泻，一个 52 岁的人进入我们的医院。结肠镜检查和钡灌肠在 S 字形的冒号在他们的顶上与粘液显示出多重憩室，显著地变厚的粘膜褶层和水虫息似的损害。内视镜的 ultrasonography 出现了粘膜、粘膜下层的层变厚。几个内视镜的活体检视标本从水虫息似的损害被拿。组织学的检查揭示了仅仅长期的煽动性的房间渗入。以便获得明确的诊断，我们在获得知情同意以后为水虫息似的损害执行了内视镜的巨大的活体检视。揭示的组织学的检查在薄板 propria 标记淋巴细胞渗入，含铁血黄素存款和纤维肌性涂去，粘膜 prolapsing 的类似于那些的特征症候群。在 anti-diarrhetic 处理以后，临床的调查结果被改进。因此，巨大的活体检视为 prolapsing 粘膜息肉的诊断和处理是有用的。

We report here a case of multiple prolapsing mucosal polyps with diverticulosis in the sigmoid colon. A 52-year- old man was admitted to our hospital because of bloody diarrhea. Colonoscopy and barium enema showed multiple diverticula, markedly thickened mucosal folds and polypoid lesions with mucus on the top of them in the sigmoid colon. Endoscopic ultrasonography showed thickening of the mucosal and submucosal layers. Several endoscopic biopsy specimens were taken from the polypoid lesions. Histological examination revealed only chronic inflammatory cell infiltration. In order to obtain a definite diagnosis, we performed endoscopic jumbo biopsy for the polypoid lesions after obtaining informed consent. Histological examination revealed marked lymphocyte infiltration, hemosiderin deposits and fibromuscular obliteration in the lamina propria, features similar to those of mucosal prolapsing syndrome. After anti-diarrhetic treatment, clinical findings were improved. Thus, jumbo biopsy is useful for diagnosis and treatment of prolapsing mucosal polyps.
