Comparison of Low and High Ligation in the Rectal Cancer

This study has been completed.

Hiroki Yamaue, Wakayama Medical University Identifier:
First received: June 17, 2008

Last verified: December 2013
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 Intervention
Rectal Cancer
Procedure: preservation of nerve fibers around IMA
Procedure: resection of nerve fibers around IMA

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (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-

Further study details as provided by Wakayama Medical University:

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

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

Enrollment: 100
Study Start Date: January 2008
Study Completion Date: December 2011
Primary Completion Date: January 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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
Other Name: high tie

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.

Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • On the basis of whether anterior resection was anticipated at WMUH for rectosigmoid and rectal cancer, and appropriate informed consent was obtained.

Exclusion Criteria:

  • Patients who could not respond to medical interview for own bowel function
  • Patients without an informed consent
