Indocyanine green (ICG) real-time blood perfusion fluorescence angiography in laparoscopic radical resection of rectal cancer has great potential clinical value and can visually judge intestinal tract blood supply to improve the surgery safety, reduce postoperative complications, and ensure the recovery of patients after surgery. Objective: To explore the efficacy of the intraoperative use of indocyanine-green fluorescence angiography in laparoscopic rectal resections in patients with rectal cancer. Methods: In the present study, 109 rectal cancer patients were included and assigned to different surgical groups [ICG and control groups] for analysis. Statistical analysis was carried out for various common postoperative complications in the two groups. Finally, the patients in the ICG fluorescence imaging group had a timely adjustment of the proximal resection of the intestinal tube before the proximal bowel of the lesion was cut off when the intestinal blood supply was insufficiently assessed by fluorescence imaging. Two subgroups, the adjustment and the non-adjustment groups, were analyzed. Results: Compared with the control group, the postoperative anal ventilation time in the ICG group was shorter than that in the control group (P 0.05). In addition, the postoperative complications were lower than those in the control group, and the differences were statistically significant (P 0.05). However, the distance between the tumor from the anal verge in the adjustment group was smaller than that in the non-adjustment group, and the difference was statistically significant (P 0.01). Conclusion: Compared with conventional laparoscopic radical resection of rectal cancer, ICG real-time indocyanine green fluore- scence angiography was safe and feasible. This technique is a promising intraoperative tool for the assessment of bowel perfusion especial展开更多
