Narrative objectives1
The aim study is to observe the functional lymphovascular network in the anorectal region using intraoperative indocyanine green fluorescence imaging in patients with rectal cancer.
Basic objectives2
Others
Basic objectives -Others
This study aims to provide the anatomical data to discuss the therapeutic strategies for early and advanced rectal cancer. This study does not aim to expand the indication of indocyanine green, and not to expect therapeutic effects of indocyanine green fluorescence imaging.

Assessment
Primary outcomes
The primary outcome of this study is the data collection of lymphovascular network in the anorectal region. The patient was administered general anesthesia, and then indocyanine green is injected into the submucosa at the anal canal. Intraoperatively, the lymph flow around the anal canal was observed using a laparoscopic near-infrared camera. The data will be the qualitatively, and statistic analyses will not be conducted.

Interventions/Control_1
The patient was administered general anesthesia, and then 0.25 mg of the dye solution of indocyanine green is injected into the submucosa of the anal canal at the anterior, posterior and bilateral walls prior to the initiation of the operation. The lymph flow around the rectum and anal canal is observed using a laparoscopic near- infrared camera intraoperatively.
