随着CT和内镜等先进技术的应用,使许多消化道肿瘤得到早期诊断,从而提高了该类疾病的存活率。大便潜血试验(FOBT)作为一种检查肠道隐性出血的简易方法也由以往普通化学法发展为多种免疫化学法。尽管人们对该法的重视较少,但并不意味着它失去了对消化道肿瘤的早期诊断价值,尤其对结直肠和小肠肿瘤的筛检和早期发现仍有肯定的意义。本文结合国内外资料和本人经验归纳介绍该试验的方法及其在消化道肿瘤中的诊断价值,以引起外科同仁对该项检查的重视。
With the application of advanced techniques such as CT and endoscopy, many gastrointestinal cancers have been diagnosed early, thereby increasing the survival rate of such diseases. The fecal occult blood test (FOBT) as a simple method for the examination of intestinal occult hemorrhage has also evolved from the previous general chemical method to a variety of immunochemical methods. Although people pay less attention to this method, it does not mean that it has lost its early diagnostic value for digestive tract tumors, especially for the screening and early detection of colorectal and small intestine tumors. This article summarizes the method of the trial and its diagnostic value in digestive tract tumors in combination with domestic and foreign data and my own experience, so as to cause surgical staff to attach importance to this examination.
