目的探究低位直肠癌经肛门直肠外翻拉出保留肛门吻合术的治疗效果。方法 2008年1月至2013年1月,对274例低位直肠癌按行保肛术,坚持将血供良好的肠断端拉下恢复肠道肛管的连续性。结果 204例行双吻合器切除术,70例行Parks术,癌基底距肛缘为5～6cm。Parks术38例为结肠与肛管吻合;改良Bacon术32例为降结肠拉出。结论对肿瘤基底距肛缘5～6cm且肿块位于直肠后壁的直肠癌可采用双吻合器切除术,其中乙状结肠较长可行Parks术,乙状结肠长度不够时可行降结肠改良Bacon术。
Objective To investigate the therapeutic effect of anorectal anastomosis by anorectal rectal pull-out of low rectal cancer. Methods From January 2008 to January 2013, 274 cases of low rectal cancer were treated with anal sphincter preservation. They insisted on pulling down the blood supplying good intestine to restore the continuity of the intestine and anal canal. Results 204 cases of double stapler resection, 70 cases of Parks surgery, cancer base from the anal margin of 5 ~ 6cm. Parks surgery in 38 cases of anastomosis of the colon and anal; Modified Bacon surgery in 32 cases of descending colon pull. Conclusions The double stapler resection can be applied to the tumor whose base is 5 ~ 6cm away from the anal verge and the mass is located in the posterior wall of the rectum. In which, the sigmoid colon is longer and Parks operation is feasible.
