目的评价高龄低位直肠癌不同吻合平面保肛手术后肛门控便功能。方法对2000～2003年39例采用保肛手术治疗的低位直肠癌病人分别按吻合口位置分组,对术后控便情况进行研究。结果病人排便次数达到正常的时间为术后(9.8±2.86)个月,术后36.1%病人出现I度失禁的表现。低位吻合组与超低位吻合组比较术后控便情况差异无统计学意义,贮袋组与直肠吻合组比较术后控便情况差异有统计学意义。结论高龄低位直肠癌低位吻合与超低位吻合术后对控便机能影响差异不明显,采用结肠贮袋直肠肛管吻合术能够明显改善高龄病人近期的控便功能。
Objective To evaluate the anal control and defecation function of different anastomosis flat anal sphincter preservation in elderly lower rectal cancer. Methods Thirty-nine cases of low rectal cancer treated with anal sphincter preservation in 2000 ~ 2003 were grouped according to the anastomotic sites, and the postoperative control was studied. Results The frequency of defecation was normal (9.8 ± 2.86) months after operation, and 36.1% of patients showed I incontinence after operation. There was no significant difference in postoperative control between the low anastomosis group and the ultra-low anastomosis group, and there was significant difference between the control group and the storage group when compared with the rectal anastomosis group. Conclusion There is no obvious difference in the control of defecation function between the lower anastomosis and the ultra-low anastomosis in the elderly patients with lower rectal cancer. The colorectal anal canal anastomosis can significantly improve the recent control of stool function in elderly patients.
