目的探讨中低位直肠癌保肛术的适应证。方法 1996年11月至2010年10月,对101例中低位直肠癌行保肛术,恢复肠道肛管的连续性。结果行双吻合器低位前切除术101例中,90例肿瘤基底距肛缘约6～8 cm,11例5～6 cm。结论对肿瘤基底距肛缘6～8 cm中低位直肠癌可以采用双吻合器低位前切除术;5～6 cm直肠腺癌,肿瘤浸润小于1/2肠周径,且基底未固定,方可采用保肛术。
Objective To investigate the indications of anal sphincter preservation in low and middle rectal cancer. Methods From November 1996 to October 2010, 101 cases of low and middle rectal cancer underwent anal sphincter preservation, to restore the continuity of intestinal anal canal. Results In the double anastomosis device, 101 cases of low anterior resection, 90 cases of tumor base from the anal verge about 6 ~ 8 cm, 11 cases 5 ~ 6 cm. Conclusions The double stapler low anterior resection can be applied to the low and middle rectal cancer of 6-8 cm from the anal verge, while the rectal adenocarcinoma of 5-6 cm in diameter is less than 1/2 of the intestinal peritumoral diameter, and the base is not fixed Using anal protection surgery.
