痔疮和直肠癌怎么样鉴别
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">痔疮和直肠癌应该<span style="color: black;">怎样</span>鉴别，这是肛肠病<span style="color: black;">病人</span><span style="color: black;">必定</span>要关注的问题！临床上，<span style="color: black;">虽然说</span>直肠癌<span style="color: black;">显现</span>便血等症状跟痔疮有些<span style="color: black;">类似</span>，但只要<span style="color: black;">重视</span>用心观察，这两种<span style="color: black;">疾患</span>的临床表现还是有很大差别的。两者应该从以下几个方面来鉴别:</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://pic1.zhimg.com/80/v2-639f6c0a9eb9798031858a02e7a27f50_720w.webp" style="width: 50%; margin-bottom: 20px;"></div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1、便血颜色：痔疮便血颜色鲜红，或排便时(便前、便时、便后)滴血、严重时会有喷血;而肠道肿瘤<span style="color: black;">流血</span><span style="color: black;">重点</span>是大便摩擦或是肿瘤组织局部坏死<span style="color: black;">导致</span>，<span style="color: black;">因此</span><span style="color: black;">都数</span>沾在大便表面，或混在大便里，血色暗红，并含有粘液，呈粘液状血便，有时仅为大便表面染有血迹；<span style="color: black;">倘若</span>是肿瘤组织局部坏死<span style="color: black;">导致</span>的<span style="color: black;">流血</span>，还会伴有腹部<span style="color: black;">病痛</span><span style="color: black;">或</span>直肠坠胀感，这是痔疮<span style="color: black;">流血</span>少见的症状。</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://pic2.zhimg.com/80/v2-927bd2b09658b3019e127f756eb06ea5_720w.webp" style="width: 50%; margin-bottom: 20px;"></div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2、大便形状：⑴大<span style="color: black;">便签</span>沟槽的鉴别：痔疮<span style="color: black;">病人</span>尤其是混合痔，其发病位置靠近肛管和肛门口，大便<span style="color: black;">尤其</span>是条形软便经过肛管和肛门口时，大<span style="color: black;">便签</span>即被<span style="color: black;">凸出</span>的痔疮塑形，从而使大<span style="color: black;">便签</span><span style="color: black;">显现</span>凹槽。值得<span style="color: black;">重视</span>的是，这种大<span style="color: black;">便签</span>上<span style="color: black;">显现</span>凹槽的现象，最多见的还是痔疮<span style="color: black;">病人</span>；直肠癌其病变部位多在痔疮以上，直肠癌<span style="color: black;">初期</span>病灶体积小，还不足以<span style="color: black;">导致</span>对大<span style="color: black;">便签</span>的挤压，从而<span style="color: black;">显现</span>大便凹槽。这一鉴别点提示<span style="color: black;">咱们</span>，大便凹槽不是直肠癌的<span style="color: black;">初期</span>症状，<span style="color: black;">仅有</span>癌肿靠近直肠末端<span style="color: black;">或</span>肛管，在病情中晚期，瘤体组织长到体积够大时才会<span style="color: black;">显现</span>;⑵肠癌<span style="color: black;">病人</span>常<span style="color: black;">显现</span>排稀便，这是<span style="color: black;">由于</span>直肠内的瘤体刺激，<span style="color: black;">或</span>是瘤体组织局部<span style="color: black;">显现</span>坏死溃疡，刺激直肠<span style="color: black;">导致</span>的。而痔疮<span style="color: black;">病人</span>除肠道本身的<span style="color: black;">原由</span>以外不会<span style="color: black;">显现</span>排稀便的症状。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">3、排便习惯：痔疮<span style="color: black;">病人</span>排便习惯<span style="color: black;">通常</span>不会<span style="color: black;">出现</span><span style="color: black;">显著</span>的变化;肠癌<span style="color: black;">病人</span>会<span style="color: black;">显现</span>大便规律的改变，大便次数<span style="color: black;">显著</span><span style="color: black;">增加</span>，<span style="color: black;">况且</span>排便时间拉长，这是<span style="color: black;">因为</span>肠道受肿瘤本身刺激<span style="color: black;">或</span>肿瘤局部坏死脱落物的刺激，令<span style="color: black;">病人</span>总有便意感，且觉得大便未排净<span style="color: black;">导致</span>。</p>
