Brief Summary:
The purpose of this study is to evaluate the defecatory function when nerve fibers around the inferior mesenteric artery(IMA) and left colic artery(LCA) are preserved(so called low ligation ) or not(high ligation) in the rectosigmoid and rectal cancer surgery.

Condition or disease Intervention/treatment
Rectal Cancer Procedure: preservation of nerve fibers around IMA Procedure: resection of nerve fibers around IMA

Detailed Description:
Fecal incontinence after anterior resection are often observed. Whether or not postoperative bowel function is influenced by the preservation of nerve fibers around the root of IMA and LCA (low ligation) is still unknown. So in this randomized controlled trial, we evaluate the efficacy of low ligation in terms of the bowel function.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 100 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Comparison of Functional Results of High Ligation and Low Ligation After Anterior Resection for Rectal Cancer - Randomized Controlled Trial-
Study Start Date : January 2008
Primary Completion Date : January 2008
Study Completion Date : December 2011

Arm Intervention/treatment
Experimental: 1
low ligation, which the IMA is ligated below the origin of the left colic artery
Procedure: preservation of nerve fibers around IMA
low ligation
Other Name: low tie
Active Comparator: 2
high ligation, which the IMA is ligated at its origin from the aorta
Procedure: resection of nerve fibers around IMA
high ligation

Primary Outcome Measures :
  1. Assessment of bowel function [ Time Frame: 1 year ]

Secondary Outcome Measures :
  1. comparison of leakage rate [ Time Frame: 2 weeks ]
