Brief Summary:
The purpose of this study is to determine: (1) whether laparoscopy-assisted nerve-preserved total mesorectal excision (LNTME) is as safe as open TME for rectal cancer, and (2) whether LNTME is more effective for protection of pelvic autonomic nerve function from surgical impairing when comparing to open TME.

Estimated Enrollment : 80 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)

Arm Intervention/treatment
Experimental: LNTME
Laparoscopy-assisted nerve-preserved TME (LNTME) is conducted in rectal cancer patients
Procedure: LNTME
Patients in this group received laparoscopy-assisted nerve-preserved TME for treatment of rectal cancer

Active Comparator: OTME
Open TME (OTME) is conducted in rectal cancer patients
Procedure: OTME
Patients in this group received traditional open TME for treatment of rectal cancer

Primary Outcome Measures :
  1. Postoperative complications including bleeding, anastomotic leakage, postoperative infection, organ dysfunctions. [ Time Frame: postoperative 30 days ]
  2. The postoperative sexual function assessed by IIEF questionnaire [ Time Frame: postoperative one year ]
  3. The postoperative voiding function assessed by IPSS questionnaire. [ Time Frame: postoperative one year ]

Secondary Outcome Measures :
  1. Operative time [ Time Frame: an expected average of 180 minutes ]
  2. Postoperative deaths [ Time Frame: postoperative 30 days ]
  3. The length postoperative hospital stay [ Time Frame: an expected average 8 days ]
  4. C-reactive protein [ Time Frame: postoperative 7 days ]
    serum C-reactive protein level after operation
