Abstract］ objective to investigate anus sphincter preserved surgical method and indication for low rectal cancer.methods 15 cases with low rectal cancer were operated with eversion and pull-through anus preserved colorectal anastomosis through anus.results no patients died of operation,no patients was with fistula and stricture of anastomosis,no defecation incontinence happened after postoperative 20 weeks,only one patient was with local recurrence.following up for 8 months to 5 years,5 cases were with distant metastasis,4 of these died,one of these had lived with liver metastasis for 3 years.conclusion the indication of anus preserved operation should be chosen according to clinical stage and biological characteristic of rectal malignancy; eversion and pull-through anus preserved colorectal anastomosis through anus is a better anus preserved operation for low rectal cancer.

目的 探讨低位直肠癌保留肛门括约肌功能的手术方法和手术适应证。方法对低位直肠癌经腹经肛门直结肠外翻拉出保留肛门吻合术15例。结果全组无手术死亡，未发生吻合口漏和吻合口狭窄，局部复发1例，20周左右恢复正常排便排气功能，无大便失禁病例。随访8个月～5年，5例为远处转移，死亡4例，其中1例肝转移3年仍生存。结论根据直肠癌的临床分期和肿瘤的生物学特性选择保肛手术适应证，经腹、肛门齿线上直肠癌根治性切除，行肛门直结肠外翻拉出吻合是低位直肠癌较好的保肛术式。

Quantitatively, the optical density of NADPH-d positive neurons in all of the related nuclei was significantly increased in the BDL animals compared with controls. Since NO is thought to be able to increase the motilities of the gallbladder and the sphincter of Oddi in anesthelized rabbits, the elevation of NADPH-d and NOS reactivities is likely to magnify the excitatory effect on the extrahepatic biliary system for the purpose of depletion of the loitered bile juice from the jaundiced liver. These data may also have important implications for the altered state of circulatory, metabolic or regenerative responsiveness under pathological condition.

此现象一来可推测，肝脏在遭受胆管阻塞性黄胆的伤害后，其代谢、血液动态与温度调节作用势必改变、紊乱、甚至失功能，而感觉神经也势必会接受到大量的机械性、化学性、渗透性等感知讯息，所以感觉神经元将一氧化氮制造量提升，有助於感觉讯息的快速传报，以发挥回馈调控的效果；二来可表示，自主神经系统不论是交感或副交感神经，为了因应胆管阻塞所造成肝脏的病变，以增加一氧化氮的制造，意欲刺激肝外胆道系统，排空滞留在肝脏内或胆囊内的胆汁，而达到恢复肝脏内代谢、血液循环、胆汁流动等功能控制的恒定状态。
