A Study Assessing Perfusion Outcomes With Near Infrared-Indocyanine Green Imaging System in Laparoscopic Total Mesorectal Excision for Mid- or Low-rectal CanceR
It is a multicenter, prospective, and randomized controlled clinical study of patients with mid- or low- rectal cancer who received laparoscopic TME surgery aims to explore whether the application of near infrared-indocyanine green imaging system can evaluate the anastomotic blood perfusion accurately, and optimize the surgical procedures, or even reduce the incidence rates of postoperative anastomotic leakage in mid- or low- rectal cancer patients.
• The age was over 18 years at the time of diagnosis;
• Diagnosis of rectal carcinoma and was confirmed by preoperative pathology;
• MRI was performed before operation, and the distance between the lower margin of tumor and the anal margin was no more than 10cm;
• The colon-rectum or colon-anus anastomosis was performed by laparoscopic TME operation
• The spleen area was not free during the operation
• Baseline clinical tumor stage TNM Ⅰ-Ⅲ phase: cT1-4N0-2M0 （AJCC-8 version）;
