A 75-year-old man who had undergone partial gastrectomy was referred to our hospital due to worsening leg edema, loose stools and malnutrition. Double balloon enteroscopy followed by insertion of an indwelling ileus tube was performed to investigate the microbial flora and for washing inside the blind loop. Trophozoites of Giardia were detected in the sampled fluid from the blind loop and DNA analysis disclosed an assemblage of genotype A-II of Giardia duodenalis. Treatment with oral metronidazole was effective. This case emphasizes the importance of a correct diagnosis when treating patients with blind loop syndrome in the digestive tract.
一名75岁男性因腿部水肿加重、腹泻和营养不良前来我院就诊，该患者曾接受过部分胃切除术。进行了双气囊小肠镜检查并插入了留置肠梗阻管，以调查微生物菌群并冲洗盲袢内部。在盲袢采集的液体中检测到贾第鞭毛虫滋养体，DNA分析显示为十二指肠贾第鞭毛虫A-II基因型组合。口服甲硝唑治疗有效。该病例强调了在治疗消化道盲袢综合征患者时正确诊断的重要性。
