节段性结肠结核常可累及升、横结肠或乙状结肠,累及直肠并不常见且缺乏特异性。本研究描述孤立性直肠结核的临床表现、内镜下特征和结果。 方法:1991～1994年发现的8例直肠结核患者(男5例、女3例,平均年龄34.6岁)。孤立性直肠结核的定义为钡剂造影发现病变局限在直肠,而小肠和结肠无病变。患者均作以下检查:血像、结核菌素试验、胸片、小肠和结肠的钡剂造影、结肠镜检查以及直肠活检。每例患者取6～10块组织作组织病理学检查,其中2～4块作抗酸杆菌涂片和培养。对初次活检不能明确诊断者,反复活检至少2次。直肠结核的诊断根据以下2项或2项以上标准:(1)内镜下有结核的特
Segmental tuberculosis often involving l, transverse or sigmoid colon, involving the rectum is not common and the lack of specificity. This study describes the clinical presentation, endoscopic features and outcome of solitary rectal tuberculosis. Methods: Eight patients with rectal tuberculosis (5 males and 3 females with a mean age of 34.6 years) were found from 1991 to 1994. Solitary rectal tuberculosis is defined as a barium contrast lesion confined to the rectum, while the small intestine and colon are non-diseased. All patients underwent the following examinations: blood tests, tuberculin tests, chest radiography, barium enema in the small intestine and colon, colonoscopy, and biopsy. Each patient took 6 to 10 tissue histopathological examination, of which 2 to 4 for acid-fast bacilli smear and culture. On the first biopsy can not be a clear diagnosis, repeated biopsy at least 2 times. The diagnosis of rectal tuberculosis based on the following two or more than two criteria: (1) endoscopic tuberculous
