慢性血吸虫病患者,因结肠纤维性变,虫卵被包围其中,不易排入肠腔,粪便中往往不易发现虫卵。因此,单以粪便检查诊断慢性血吸虫病,检出率远较实际为低。采用乙状结肠镜检可弥补此缺点,但在不少单位开展此项检查尚有困难。应用直肠粘膜压片镜检,操作较为简便,易在广大农村和基层卫生单位采用,检出率并不低于乙状结肠镜检,且比较安全,检查时痛苦少。在血吸虫病流行地区,本方法可作为对粪检阴性的可疑患者常规检查项目。
Chronic schistosomiasis patients, due to changes in colon fibrosis, eggs are surrounded by them, not easily discharged into the intestine, feces are often not easy to find eggs. Therefore, the single diagnosis of chronic schistosomiasis examination, the detection rate far lower than the actual. The use of sigmoidoscopy can make up for this shortcoming, but there are still many difficulties in carrying out this test in many units. The application of rectal mucosal compression microscopy, the operation is relatively simple, easy to use in the vast rural areas and grass-roots health units, the detection rate is not lower than the sigmoidoscopy, and more safe, less painful examination. In areas where schistosomiasis is endemic, this method can be used as a routine test item for suspect patients who are fecal negative.
