<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">痔疮便血的特点是排便中或便后<span style="color: black;">流血</span>，色鲜红，如下图所示。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">有时大便表面附有少量血液或将手纸染红，有时为滴血，有时可见血液呈喷射状，便后<span style="color: black;">流血</span>多<span style="color: black;">自动</span>停止。若<span style="color: black;">长时间</span>反复<span style="color: black;">流血</span>或多次<span style="color: black;">海量</span><span style="color: black;">流血</span>，还可<span style="color: black;">导致</span>贫血。（<span style="color: black;">照片</span>不宜展示）</span></p><span style="color: black;">直肠癌<span style="color: black;">流血</span></span>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">痔疮除便血外还有以下症状：</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">① 内痔脱出：<span style="color: black;">初期</span>仅有便血，<span style="color: black;">无</span>脱出；二期内痔伴有排便脱出，便后能<span style="color: black;">自动</span>回纳；三期<span style="color: black;">不可</span><span style="color: black;">自动</span>回纳，须用手回纳，<span style="color: black;">乃至</span>在用力或咳嗽时均可脱出。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><img src="https://mmbiz.qpic.cn/mmbiz_jpg/vsVIhIVQ6Mm8GNvjO1uu7pnuo2iawG35xgMQp9Il5PKmY64fOMHVOl6aZMCEwiagseIT1LibpeGNEBLAGIHwkOicAA/640?wx_fmt=jpeg&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;"></span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">① 直肠刺激症状。<span style="color: black;">平常</span>腹泻，里急后重及排便不尽感，有时每日排便数次，但每次量不多。部分<span style="color: black;">病人</span>可表现为腹泻及便秘交替<span style="color: black;">显现</span>。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">② 癌肿破溃感染症状。<span style="color: black;">平常</span>大便带有脓血及黏液，<span style="color: black;">通常</span><span style="color: black;">流血</span>量较少，血呈鲜红色或稍暗，<span style="color: black;">附着</span>大便表面，便血常为间歇性，<span style="color: black;">少许</span>病例可<span style="color: black;">出现</span><span style="color: black;">海量</span><span style="color: black;">流血</span>，<span style="color: black;">病人</span>有肛门下坠不适感。</span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">③ 肠腔狭窄梗阻症状。癌肿浸润肠壁使肠腔狭窄，<span style="color: black;">导致</span>大便变细变形，严重时<span style="color: black;">显现</span>排便困难。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">④ 消耗征象。恶性肿瘤<span style="color: black;">长时间</span>慢性消耗，可<span style="color: black;">显现</span>贫血、消瘦等恶病质征象。</span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">倘若</span>感到肠内有形状不规则、边缘不整齐、表面<span style="color: black;">不但</span>滑的菜花状硬块或边缘隆起中央凹陷的溃疡，并<span style="color: black;">发掘</span>肠腔狭窄得仅能容纳一个手指；<span style="color: black;">检测</span>后，指套上沾有血液、黏液者，则极可能患上了直肠癌。</span></p>
