Clinical Value of Left Colic Artery in Laparoscopic Radical Rectectomy

December 2, 2017 updated by: Shanghai Minimally Invasive Surgery Center

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: LCA-nP
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.
The group underwent lapaoroscopic radical rectectomy without preserving left colic artery.
Active Comparator: LCA-P
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.
The group underwent lapaoroscopic radical rectectomy with preserving left colic artery.
