The diagnosis of giardiasis is frequently difficult to make. The routine procedure of multiple stool examinations fails to detect Giardia lamblia trophozoites or cysts in 30-50% of cases. Small bowel biopsy and aspirate are believed to be the best way to make the diagnosis of giardiasis if the organism is not found in the stool and the diagnosis is still suspected. We describe two patients whose diagnosis of giardiasis was established by endoscopic brush cytology of the duodenal mucosa. The first patient had negative stool examinations, duodenal biopsy, and duodenal aspirate.
贾第虫病的诊断常常很难做出。多次粪便检查的常规程序在30%-50%的病例中未能检测到蓝氏贾第鞭毛虫滋养体或包囊。如果在粪便中未发现病原体而仍怀疑患有贾第虫病，小肠活检和抽吸被认为是诊断该病的最佳方法。我们描述了两名通过十二指肠黏膜内镜刷检细胞学确诊为贾第虫病的患者。首例患者的粪便检查、十二指肠活检和十二指肠抽吸均为阴性。
