目的探讨经过选择的低位直肠癌患者中双吻合器技术在全系膜切除保肛手术中的价值。方法对距肛缘4～7cm的低位直肠癌患者56例行结直肠吻合保肛手术。结果全组无手术死亡,术后发生吻合口漏1例(1．8％),吻合口狭窄7例(12．5％)。术后局部复发3例,其中2例为吻合口复发,1例为盆腔复发,总局部复发率为5．4％。结论只要合理选择手术适应证,全系膜切除结合双吻合器技术在低位直肠癌保肛手术中是安全可靠的。
Objective To investigate the value of double stapling technique in total mitral sphincter preservation in selected low rectal cancer patients. Methods 56 cases of colorectal anastomosis and anus preservation operation were performed on 56 patients with low rectal cancer located 4 ~ 7cm from the anal verge. Results All the patients died without surgery. Anastomotic leakage occurred in 1 case (1.8%) and anastomotic stenosis in 7 cases (12.5%). Postoperative local recurrence in 3 cases, of which 2 cases of anastomotic recurrence, pelvic recurrence in 1 case, the total local recurrence rate was 5.4%. Conclusion As long as a reasonable choice of surgical indications, total mesotrustomy combined with double stapling technique in the low rectal cancer anus surgery is safe and reliable.
