直肠癌前切除超低位吻合术后肛门功能改变及其机制探讨

Ultralow Anterior Resection for Rectal Anal Anastomosis Function Change & its mechanism

我国低位直肠癌较为多见,过去Mile's术是治疗低位直肠癌的"黄金标准",现在保肛术已占直肠癌外科治疗的70%。但是术后患者的肛门功能并太令人满意,许多学者从肛肠动力学方面探讨了前切除综合征的发生机制,认为主要与肛门内外括约肌损伤、新建直肠的顺应性改变、内括约肌反射通路神经损伤及排便感觉变化等有关。

Low rectal cancer is common in China, Mile’s treatment of rectal cancer surgery in the past is the ＂gold standard＂ rectal surgery which now accounts for 70% of surgical treatment of rectal cancer. However, postoperative anal function is far beyond satisfaction. Many scholars from the respect of anorectal dynamics discuss the mechanism of anterior resection syndrome, and meanwhile point out that the low retacl cancer is closely related to major internal and external anal sphincter injury, the new changes in rectal compliance, sphincter reflex sensory nerve injury and changes in the bowel.
