目的探讨原发性大肠非霍奇金淋巴瘤(NHL)的内镜表现,以提高对原发性大肠非霍奇金淋巴瘤的诊断率。方法回顾性分析近6年来我院经手术及病理证实的8例原发性大肠NHL临床和内镜资料。结果病变部位位于盲肠者占62.5%。内镜下表现为弥漫型3例,溃疡型4例,息肉型1例。电子结肠镜检查结合病理组织活检诊断阳性率达87.5%。结论本病好发于盲肠,多为单发病灶。本组病例中内镜下病灶形态表现以溃疡型多见。结肠镜检查联合内镜下活检、免疫组织化学检查有助于提高对大肠NHL内镜诊断阳性率。
Objective To explore the endoscopic features of primary colorectal non-Hodgkin’s lymphoma (NHL) in order to improve the diagnostic rate of primary non-Hodgkin’s lymphoma. Methods The clinical and endoscopic data of 8 cases of primary colorectal NHL confirmed by operation and pathology in our hospital during the past 6 years were retrospectively analyzed. Results lesions located in the cecum accounted for 62.5%. Endoscopic showed diffuse in 3 cases, 4 cases of ulceration, polypoid in 1 case. Electronic colonoscopy combined with pathological biopsy diagnosis of positive rate of 87.5%. Conclusion The disease occurs in the cecum, mostly single lesions. Endoscopic lesions in this group of patients with the appearance of ulcers more common. Colonoscopy combined with endoscopic biopsy, immunohistochemical examination can help improve the positive rate of colon NHL endoscopy.
