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.
