鉴于美兰溶液作为活体染色剂已成功地用于胃镜和支气管镜检查,作者研究了在结肠镜检查时利用美兰溶液诊断某些结肠疾病的可能性,目的在于寻求在结肠内窥镜检查中使用美兰溶液的简易方法和确定其能否检出结肠粘膜病变。起初作者在做纤维结肠镜检查时试图通过聚乙烯导管将0.25％美兰溶液直接注入结肠腔内。由于无法从结肠中清除过多的美兰溶液,不能获得有关结肠粘膜状态的资料而不得不放弃该法。后来用1.5升0.25％的美兰溶液灌肠,取得了预期的效果。临床检查共分为两组,第一组,采用0.25％美兰溶
Since melanin solution has been successfully used for endoscopy and bronchoscopy as a living stain, the authors investigated the possibility of using melanin solution for the diagnosis of certain colon diseases during colonoscopy, with the aim of seeking endoscopic colonoscopy Use a simple method of melanin solution and determine whether it can detect colonic mucosal lesions. Initially, the author attempted to directly inject a 0.25% melanin solution into the colon lumen through a polyethylene catheter while doing a fiberoptic colonoscopy. Due to the inability to remove excessive melanin from the colon and to obtain information on the condition of the colon mucosa, the law had to be abandoned. Later with 1.5 liters of 0.25% Methimazole enema, and achieved the desired results. Clinical examination is divided into two groups, the first group, the use of 0.25% Meilan dissolved
