Prospective registry study of endoscopic submucosal injection of indocyanine green before laparoscopic radical resection for colorectal cancer
To observe the imaging result of endoscopic submucosal injection of indocyanine green before laparoscopic radical resection for colorectal cancer, and analyze the relevant factors, so as to guide the submucosal injection of preoperative indocyanine green better.
This study is prospective and observational. In order to analyze the related factors that affect the imaging effect, we enrolled patients who were to undergo indocyanine green fluorescence imaging for laparoscopic radical resection for colorectal cancer.

Patients who were to undergo indocyanine green fluorescence imaging for laparoscopicradical operation of colorectal cancer.
Exclusion Criteria:
have simultaneously other cancer
Procedure: endoscopic submucosal injection of indocyanine green before laparoscopic radical operation of colorectal cancer
Indocyanine green was injected under endoscope within 24 hours before operation. Four points were evenlyinjected in four quadrants at the edge of the tumor. The patients with obstruction were injected at two points on the anal side of the tumor. The diluted concentration of indocyanine green was 0.625mg/ml or 1.25mg/ml. The injection method was direct submucosal injection and sandwich method. According to the imaging effect, it can be divided into local imaging and lymphatic drainage imaging. Tumor body: 0, no imaging; 1, full imaging; 2, diffuse imaging, overflow, interference with other areas of observation. Lymph drainage area imaging 0, no imaging; 1, full imaging; 2, diffuse imaging, overflow, interference with other areas of observation.
The imaging effect of indocyanine green
The imaging effect was evaluated by indocyanine green fluorescence imaging system during the operation. According to the imaging effect, it can be divided into local imaging and lymphatic drainage imaging. Tumor body: 0, no imaging; 1, full imaging; 2, diffuse imaging, overflow, interference with other areas of observation. Lymph drainage area imaging 0, no imaging; 1, full imaging; 2, diffuse imaging, overflow, interference with other areas of observation.
Time frame: During the operation
