两种直肠癌根治术应用于全直肠系膜切除术后局部复发率的比较

目的：比较保肛与非保肛两种直肠癌根治术应用全直肠系膜切除（total mesorectal excision,TME）后的局部复发率的（local recurrence rate,LRR）差异。方法：173例直肠癌患者分2组（Dixon组123例,Miles组50例）,按Heald法行TME。结果：Dixon组与Miles组的总LRR分别为4．8％（6／123）与18．0％（9／50）,P＜0．05;1997年以前Miles组的LRR为36．8％（7／19）,显著高于1997年以后Miles组的6．5％（2／31）,P＜0．05;前者与Dixon组的LRR4．8％相比差异有非常显著性意义,后者与Dixon组相比差异无显著性差义,P＞0．05。结论：TME是降低2种直肠癌根治术后LRR的重要因素。

Comparison of local recurrence of rectal cancer after two radical operations using total mesorectal excision

Objective To compare the difference in local recurrence Dixon and Miles groups after total mesorectal excision. Methods One hundred and seventy three patients with rectal cancer were divided into two groups (Dixon group, 123 patients; Miles group 50 patients). Total mesorectal excision was made according to Heald's method. Results The local recurrence in the Dixon and Miles groups was 4.8% (6/123) and 18 0% (9/50) respectively ( P < 0 05), and in the Miles group before and after 1997 was 36 8% (7/19) and 6 5% (2/31) respectively ( P < 0 05), 4 8% in LRR ( P < 0 01). No significant difference was observed in the local recurrence between the two groups ( P > 0 05). Conclusion Total mesorectal excision is an important factor reducing local recurrence after radical operation for rectal cancer.
