Study of Colorectal Anastomosis Failures With First Sigmoid or Left Colonic Artery Preservation With D3 Lymphadenectomy

"This study aims to determine the incidence of anastomosis failure in the group with first SA and LCA preservation in order to identify the feasibility of manipulation.~The study is unique in that there is only one study in the world that evaluates the incidence of anastomosis failure with preservation of the first sigmoid and there is no study comparing the groups described in this study."
