作者报道一例14岁粪检阿米巴原虫阳性的慢性阿米巴痢疾患者,经用吐根素等各种抗阿米巴药物治疗和甲硝哒唑口服治疗后,仅使肠道症状获得暂时缓解,虽经多次新鲜粪检阴性,但7个月后直肠镜取粘液作寄生虫学检查仍发现有溶组织内阿米巴原虫。因此作者改用为期两周的甲硝哒唑混悬液结肠保留灌肠。以后经两次间隔4天直肠镜取粘液检查未再查到阿米巴原虫。作者从该例报告中得出两个结论:(1)寻找阿米巴的最好方法是洗拭直肠后立即取直肠粘液(而不是大便)涂片镜检,在治疗前 The authors report that a 14-year-old patient with chronic amebic diarrhea-positive chronic amoebic dysentery was treated with various anti-amoebicides and other oral metronidazole treatments with ibuprofen for only temporary gut symptoms Although many fresh fecal tests negative, but after 7 months to take mucus for rectal examination for parasites still found within the organization of Entamoeba histolytica.
