耻骨直肠肌

The mechanisms of feces control is followed:(1)Perception of oncotic pressure by anal activates the kinetic response of defecation control;(2)The tension of the internal sphincter muscle of anus makes it closed inmost of the time.(3)Tension of anal sphincter and puborectalis mantain the angle between rectum and anal canal and make anal canal closed during the relaxation of anal sphincter ;(4)adaptability of rectum makes rectum engorge in the cases of the not too high pressure of rectum .Destruction of any mechanism above will result in fecal incontinence .

正常人的大便节制主要通过下列机制调控：(1)直肠对膨胀压的感知，激发控制排便节制的动力学反应；(2)肛门内括约肌的张力，使肛管在大部分时间处于关闭状态；(3)肛门外括约肌和耻骨直肠肌的张力，使得在肛门内括约肌松弛期间，维持肛管直肠角的存在，并使肛管处于闭锁状态；(4)直肠适应性，使得在直肠内压不致过高情况下，允许直肠充盈，上述机制中一种或几种受到破坏，就可以引起大便失禁。

2The anterior cutereous branches of the obturator artery penetrate deepfascia of thigh and epimysium of the adductor muscles closing against the lower rami of pubisor at its outer margin.Pudendal-thigh skin flap pedicled on it may be elevated to repairrectovaginal fistula or small skin defects of perineum.As its piercing point is much higher andthe location of pedicle is more fixed because of restriction of pubic rami,it is not suited toreconstruct new vagina.Moreover,it is not appropriate naming the obturator aretry(or themedial femoral circumflex artery)the pudendal-thigh artery.

闭孔动脉前皮支紧邻耻骨下支或于其外侧缘，穿大腿深筋膜和内收肌肌膜浅出，以之为蒂可以形成皮下蒂阴股沟岛状皮瓣，用于阴道直肠瘘或会阴部较小皮肤缺损的修复，但由于闭孔动静脉前皮支浅出点位置较高，并且由于耻骨下支的阻挡和限制，致使血管蒂的位置较为固定，以之为蒂形成的阴股沟皮瓣不适宜用于阴道再造；另外，将闭孔动脉命名为阴股沟动脉，也有欠妥帖。

Methods According to mechanics principle of anus and rectum,adopted close neoplasty operation through rectum cope with 23 cases patient of rectocele,and injected the tela submucosa in ahead rectum with 1:1 Xiao Zhi Ling injection(Xiao Zhi Ling: Sterile Water for Injection)and cut a part of puborectalis.

依据排便时肛门、直肠作用力学原理，对23例直肠前突患者采用直肠前突经直肠闭式修补术，1∶1消痔灵直肠前壁黏膜下注射，辅助耻骨直肠肌部分离断术。

Results in 260 case,there are abnomal of 179 cases in barium enema,including 119 cases with sigmoid colon tediously lons,69 cases with transverse colon prolapse,in defecography,there are abnomal of 217 cases including 174 cases with rectocele,73 cases with rectal mucosal prolapse,87 cases with puborectalis syndrome,and 73 cases with spastic pelvic floor syndrome,many cases have two or more abnomal show.

结果 260例便秘患者中，钡剂灌肠有异常179例，其中乙状结肠延长、迂曲119例；横结肠下垂69例。排粪造影有异常217例，其中直肠前突174例；直肠黏膜脱垂73例，耻骨直肠肌综合征87例，盆底肌痉挛综合症73例；较多患者两者检查均有异常。

Methods Twentysix patients with rectocele was treated by mucosal sleeve resection by stapler or rectal mucosal flap longitudinal resection and continuous suture, and XiaoZhiLing injection and posterior pubococcygeal muscle partial section were adopted selectively.

采用经肛门直肠下端黏膜吻合器环切、纵行直肠黏膜瓣切除连续缝合术。并针对直肠前突的不同合并症，选择性地进行消痔灵注射、后位耻骨尾骨肌部分切断综合治疗26例。

Objective: To evaluate the efficacy of modified partial resection of puborectalis muscle in the treatment of puborectalis muscle syndrome.

目的：观察改良松解术式治疗耻骨直肠肌综合征的临床效果。

In order to research on the method of reconstructing anus in situs, we reconstructed artificial anus with remaining nervi haemorrhoidales superiors and musculus puborectalis.

文摘：为研究保留耻骨直肠肌重建原位肛门治疗直肠癌的方法，在手术治疗低位直肠癌且无法保肛术式的基础上，保留痔上神经以及所支配的耻骨直肠肌重建原位肛门20例。

Squeeze pressure, generated by contraction of the external anal sphincter and puborectalis muscle, more than doubles intra–anal canal resting pressure.

挤压力主要由外括约肌及耻骨直肠肌的收缩产生，通常是静息压的2倍。

Methods to improve anorectal function after anterior re section include autonomic nerve preservation, puborectalis muscle preservation and anorectal angle restruction, etc.

针对以上前切除术后的病理生理改变，许多学者提出了一系列方法来改善前切除术后的肛门直肠功能，包括术中保留植物神经、保留耻骨直肠肌及肛门直肠角重建以及增加新建直肠的容量。
