＜正＞ Objective To study the dissection technique of total mesorectal excision （TME）.Method One hundred and twelve cases of rectal cancer underwent TME from January 2000 to August 2008were retrospectively analyzed. Results All the procedures were conducted successfully, average blood losswas （45±32） ml during the dissection of rectal mesentery, the hypogastric nerves were preserved in 96cases, urinary retention occurred in 6 cases and recovered 1 month later. Anastomotic leakage occurred in 1case and healed after transverse colostomy. Wound infection in 6 cases and healed by dress changing. Therewas no ureter injury. There were 14 cases of death, 6 cases of recurrence and 15 cases of distal metastasisaccording to（3.7±1.1） years follow-up in 112 cases. The survival rate of 1,3,5 years was 92.0%（103/112）,84.8%（95/112）,66.1%（74/112） respectively. Conclusion Anatomical dissection adequate exposure and hemostasis are critical factors for TME.
