血吸虫的确实诊断主要是靠实验室的检查,即从病人的粪便中找出虫卵或孵化毛蚴,但这种方法在某些情况下,并不完全可靠,特别是晚期患者,其虫卵所在处的肠粘膜已有显著的纤维化病变,虫卵已被包围而无法进入粪便内,所以检查结果往往是阴性,以致延误了早期的治疗。因此各学者都在积极为本病的诊断方法进行着研究与改良。本文介绍的直肠活体组织检查法,即为血吸虫诊断方法之一,据许多文献报告,此法效果很好,阳性检出率很高。兹将此法作一简单介绍如下。
The true diagnosis of schistosomiasis is mainly based on laboratory tests that find eggs or hatching miracidia from the patient’s stool, but this method is not entirely reliable in some cases, especially in advanced patients, where the egg is Department of intestinal mucosa has significant fibrosis, the eggs have been surrounded and can not enter the stool, so the test results are often negative, resulting in the delay of early treatment. Therefore, all scholars are active in the diagnosis of the disease for research and improvement. This article describes the rectal biopsy, which is one of the diagnostic methods for schistosomiasis, according to many reports, this method is very good, the positive detection rate is high. Here is a brief introduction to this method.
