内镜手术干预后确诊的孤立性直肠结核球1例

Isolated rectal tuberculoma diagnosed after endoscopic surgery:a case report

肠结核好发于回盲部、回肠末端等, 极少见于直肠, 单独累及直肠更是罕见。本文介绍1例孤立性直肠结核球患者:女, 44岁, 彝族, 因腹胀、便秘入院, 既往有乙型病毒性肝炎病史, 肠镜提示直肠肿物, 行内镜下切除术。术后病理检查提示直肠结核, 未发现直肠外结核感染证据, 最终诊断为孤立性直肠结核球。对于内镜检查提示直肠肿物, 尤其合并有HIV、糖尿病等免疫功能抑制的疾病时, 需考虑结核球可能。

Intestinal tuberculosis commonly affects the ileocecal area and the terminal ileum,and is extremely rare in the rectum,with isolated rectal involvement being even rarer.This paper described a case of an isolated rectal tuberculoma in a female patient of 44 years old,Yi ethnicity,who was admitted to the hospital with abdominal distension and constipation.She had a history of hepatitis B virus infection.A colonoscopy revealed a rectal mass,and an endoscopic resection was performed.Post-operative pathological examination confirmed rectal tuberculosis,with no evidence of extra-rectal tuberculosis infection found.The final diagnosis was an isolated rectal tuberculoma.In cases where endoscopic examination suggests a rectal tumor,especially in patients with immunosuppressive conditions such as HIV or diabetes,the possibility of tuberculoma should be considered.
