style=\"font-family:宋体\">　　肛管血管垫是位于肛管和直肠的一种组织垫，简称</span>“肛垫”，系出生后就存在的解剖现象。当肛垫松弛、肥大、出血或脱垂时，即产生痔的症状。肛垫由3部分组成：①静脉，或称静脉窦;②结缔组织;③Treitz肌，该肌是指介于肛门衬垫和肛管内括约肌之间的平滑肌，它具有固定肛垫的作用，当Treitz肌肥厚或断裂时，肛垫则脱垂。Goligher认为，若在痔切除时保留Treitz肌，则可防止损伤括约肌，减少手术创面，有利伤口愈合。他报告100例，80%创口一期愈合，术后疼痛轻，多数人排便无痛苦。正常情况下，肛垫疏松地附着在肌肉壁上，排便后借其自身的纤维收缩作用，缩回肛管。当肛垫充血或肥大时，即易受伤而出血，并可脱出于肛管外;肛垫充血的程度除受肛管压力影响外，如便秘、妊娠等，还与激素、生化因素及情绪有关。</span></p><p

style=\"margin-right:0;margin-left:0;text-indent:0;text-autospace:ideograph-numeric;text-align:justify;text-justify:inter-ideograph;line-height:200%\"><span style=\";font-family:宋体;line-height:200%;font-size:16px\">　　一、解剖学原因：人在站立或坐位时，肛门直肠位于下部，由于重力和脏器的压迫，静脉向上回流颇受障碍。直肠静脉及其分枝缺乏静脉瓣，血液不易回流，容易瘀积。其血管排列特殊，在不同高度穿过肌层，容易受粪块压迫，影响血液回流。静脉又经过粘膜下层的疏松组织，周围缺乏支架固定，容易扩张屈曲。</span></p><p style=\"margin-right:0;margin-left:0;text-indent:0;text-autospace:ideograph-numeric;text-align:justify;text-justify:inter-ideograph;line-height:200%\"><span

style=\";font-family:宋体;line-height:200%;font-size:16px\">　　二、遗传关系：静脉壁先天性薄弱，抗力减低，不能耐受血管内压力，因而逐渐扩张。</span></p><p style=\"margin-right:0;margin-left:0;text-indent:0;text-autospace:ideograph-numeric;text-align:justify;text-justify:inter-ideograph;line-height:200%\"><span style=\";font-family:宋体;line-height:200%;font-size:16px\">&nbsp;</span></p><p style=\"margin-right:0;margin-left:0;text-indent:0;text-autospace:ideograph-numeric;text-align:justify;text-justify:inter-ideograph;line-height:200%\"><span style=\";font-family:宋体;line-height:200%;font-size:16px\">　　三、职业关系：人久站或久坐，长期负重远行，影响静脉回流，使盆腔内血流缓慢和腹内脏器充血，引起痔静脉过度充盈，静脉壁张力下降，血管容易瘀血扩张。又因运动不足，肠蠕动减少，粪便下行迟缓，或习惯性便秘，可以压迫和刺激静脉，使局部充血和血液回流障碍，引起痔静脉内压力升高，静脉壁抵抗力降低。</span></p><p style=\"margin-right:0;margin-left:0;text-indent:0;text-autospace:ideograph-numeric;text-align:justify;text-justify:inter-ideograph;line-height:200%\"><span

style=\";font-family:宋体;line-height:200%;font-size:16px\">　　四、局部刺激和饮食不节：肛门部受冷、受热、便秘、腹泻、过量饮酒和多吃辛辣食物，都可刺激肛门和直肠，使痔静脉丛充血，影响静脉血液回流，以致静脉壁抵抗力下降。</span></p><p style=\"margin-right:0;margin-left:0;text-indent:0;text-autospace:ideograph-numeric;text-align:justify;text-justify:inter-ideograph;line-height:200%\"><span style=\";font-family:宋体;line-height:200%;font-size:16px\">&nbsp;</span></p><p style=\"margin-right:0;margin-left:0;text-indent:0;text-autospace:ideograph-numeric;text-align:justify;text-justify:inter-ideograph;line-height:200%\"><span style=\";font-family:宋体;line-height:200%;font-size:16px\">　　五、肛门静脉压力增高：因肝硬变，肝充血和心脏功能代偿不全等，均可使肛门静脉充血，压力增高，影响直肠静脉血液回流。</span></p><p style=\"margin-right:0;margin-left:0;text-indent:0;text-autospace:ideograph-numeric;text-align:justify;text-justify:inter-ideograph;line-height:200%\"><span

style=\";font-family:宋体;line-height:200%;font-size:16px\">　　六、腹内压力增加：因腹内肿瘤、子宫肿瘤、卵巢肿瘤、前列腺肥大、妊娠、饮食过饱或蹲厕过久等，都可使腹内压增加，妨碍静脉的血液回流。</span></p><p style=\"margin-right:0;margin-left:0;text-indent:0;text-autospace:ideograph-numeric;text-align:justify;text-justify:inter-ideograph;line-height:200%\"><span

style=\"margin-right:0;margin-left:0;text-indent:0;text-autospace:ideograph-numeric;text-align:justify;text-justify:inter-ideograph;line-height:200%\"><span style=\";font-family:宋体;line-height:200%;font-size:16px\">　　七、肛门部感染：痔静脉丛先因急慢性感染发炎，静脉壁弹性组织逐渐纤维化而变弱，抵抗力不足，而致扩大曲张，加上其它原因，使静脉曲张逐渐加重，生成痔块。</span></p><p style=\"margin-right:0;margin-left:0;text-indent:0;text-autospace:ideograph-numeric;text-align:justify;text-justify:inter-ideograph;line-height:200%\"><span

style=\";font-family:宋体;line-height:200%;font-size:16px\"><span style=\"font-family:宋体\">　　痔块主要由扩张静脉、海绵状组织和结缔组织间质构成。静脉扩张弯曲，其壁变薄，外膜和中层萎缩，壁内弹力纤维组织变成纤维组织</span>[ 也有的静脉无改变 ]。静脉内可有血栓形成，静脉外有血块。常有急慢性炎症，可见因细胞浸润，有时形成小脓肿。海绵状组织，叫直肠海绵体，由很多血管小球组成，球内有短小并能弯曲的小动脉。有时有动静脉瘘，在痔块内可摸到动脉搏动。内痔表面是柱状上皮，外痔表面是鳞状上皮。</span></p><p
