The average number of No.12a lymph node dissection was (2.4 \u00b1 1.95) and the metastasis rate of No.12a lymph node was 16% (4\/25).

The mean intraoperative blood loss was (134.0 \u00b1 65.7) ml, and postoperative first anal exhaust time was (2.24 \u00b1 0.86) d. The mean time to fluid intake was (4.2 \u00b1 1.7) d, and postoperative hospitalization time was (9.6 \u00b1 5.0) d.
