UNASSIGNED: An asymptomatic 71-year-old man visited our hospital for a colonoscopy after a positive fecal occult blood test.
UNASSIGNED: Colonoscopy revealed diffuse edematous and erosive mucosa in the terminal ileum. Mycobacterium tuberculosis was detected by polymerase chain reaction and culture of biopsy specimens from the erosions, leading to the diagnosis of intestinal tuberculosis. The patient was treated with antitubercular agents for 6 months, and a follow-up colonoscopy revealed healing of the lesions.
UNASSIGNED: Asymptomatic intestinal tuberculosis may occasionally be detected on colonoscopy following a positive fecal occult blood test and is sometimes confined to the terminal ileum. Therefore, clinicians should consider intestinal tuberculosis in the differential diagnosis of the causes of positive fecal occult blood test results and perform colonoscopies, including observation of the terminal ileum.
■一名无症状的71岁男子在粪便隐血试验阳性后到我院进行结肠镜检查。
■结肠镜检查显示回肠末端弥漫性水肿和糜烂粘膜。通过聚合酶链反应和来自糜烂的活检标本的培养来检测结核分枝杆菌,导致肠结核的诊断。患者接受抗结核药物治疗6个月,随访结肠镜检查显示病变愈合。
■在粪便潜血试验阳性后,结肠镜检查偶尔会发现无症状肠结核,有时仅限于回肠末端。因此,临床医师在鉴别诊断粪便隐血检测结果阳性的原因时应考虑肠结核,包括观察末端回肠。
