血吸虫肠病的临床及内镜特点分析

目的探讨血吸虫肠病的临床及内镜特点。方法回顾性分析61例经病理检查发现肠粘膜血吸虫卵沉积而确诊为肠道血吸虫病患者的病史、内镜表现、病理特点。结果血吸虫肠病患者多以鲜血便和粘液脓血便为主述就诊，大多数既无血吸虫感染史也无明确疫水接触史；肠道最易累及部位为直肠和乙状结肠，以糜烂、溃疡、点片状出血为主要表现，部分合并结肠癌。结论血吸虫肠病是一危害较大的疾病，应提高疫区居民及内镜医师对血吸虫肠病的认识，做到早诊断、早治疗，防止其癌变。

Investigating of the Clinical and Colonoscopic Findings of Intestinal Schistosomiasis

Objective To investigate the clinical features and colonoscopic findings in patients with intestinal schistosomiasis infection. Method Retrospective analysis of 61 patients with schistosomiasis egg deposits in the intestinal mucosa was performed. The patients＇ history, colonoscopy findings, and pathological features were analyzed. Result Most of the patients with intestinal schistosomiasis had definite symptoms, such as stools containing blood or blood with pus. Most of them did not have history of infection or obvious history of contacting with contaminated water. The colon and sigmoid colon were the commonest sites of infection. Erosions, ulcerations, and localized bleeding were the major pathological features. Malignancy of the colon was also found in a few cases. Conclusion Intestinal schistosomiasis is a serious parasitic infection. It is important to educate people living in the endemic areas, and to increase the awareness of endoscopists on schistosomiasis. Early diagnosis and treatment would hopefully prevent the subsequent development of malignancy in colon.
