About this study
Official title: Randomized Controlled Trial: Clinical Value of Preserving Left Colic Artery in Laparoscopic Radical Rectectomy
Colorectal cancer is one of the most common tumors in Asia. According to the recent research, surgical procedure could provide more treatment benefit in rectal cancer. Therefore, it was consider that important to standardized and improved the surgical procedure for rectal cancer. With the development of anatomical technique, minimally surgery with laparoscopy had become the trend for surgical treatment. There were several studies has been done to evaluate the safety and feasibility of laparoscopic surgery. In order to achieve better surgical outcome and reduce operative complications, the investigators design stratified randomization, double blinded, muti - center clinical trail to investigate the value of left colic artery in laparoscopic radical rectectomy.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
LCA-nPProcedure or surgery
The group underwent lapaoroscopic radical rectectomy without preserving left colic artery.
LCA-PProcedure or surgery
The group underwent lapaoroscopic radical rectectomy with preserving left colic artery.
| Study group | Role | What they receive |
|---|---|---|
| LCA-nP | Experimental | The group underwent laparoscopic radical rectectomy without preserving left colic artery. In IMA group, the dissecting based on TME is performed without preserving left colic artery. Surgeon should dissect the lymph nodes and ligated the vessel in the root of inferior mesenteric artery. Receives: Procedure: LCA-nP |
| LCA-P | Active comparator | The group underwent laparoscopic radical rectectomy with preserving left colic artery. In LCA group, the dissecting based on TME is performed with preserving left colic artery. The relationship of inferior mesenteric artery, inferior mesenteric vein and LCA should be identified and ligated separately without LCA. Receives: Procedure: LCA-P |
What is being measured

Questions about this trial
What is this clinical trial studying?
A study testing LCA-nP and LCA-P in people with Overall Survival and Postoperative Complications, run by Shanghai Minimally Invasive Surgery Center at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 5 Dec 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Minhua Zheng, PhD (+86-13564119545, zmhtiger@yeah.net), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Disease-free survival (time frame: 3 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03349788, which also lists 9 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
