| Summary: | [Objectives] To analyze the application effect of indocyanine green fluorescence imaging (ICG-FI) technology in laparoscopic radical resection of colorectal cancer. [Methods] The clinical data of 44 patients who underwent laparoscopic radical resection of colorectal cancer with ICG-FI technology to assist in assessing the blood supply at the anastomosis site from August 2020 to October 2023 were retrospectively analyzed. The intraoperative ICG-FI, surgical indicators (operation time, intraoperative blood loss, number of intraoperative lymph node yield), and postoperative complications [anastomotic leakage (AL), ileus, anastomotic bleeding, abdominal infection, urinary tract infection, pneumonia] were recorded and analyzed. The patients were divided into an AL group and a non-AL (NAL) group based on whether AL occurred postoperatively. The relevant indicators of ICG-FI at the anastomosis site in these two groups were analyzed, including fluorescence difference between maximum and baseline (FMAX), time from first fluorescence increase to maximum (TMAX), time from first fluorescence increase to half of maximum(T1/2MAX), and the slope of the ascending curve of fluorescence intensity over time (“curve slope”). [Results] Thirty-four (77.3%) patients had intraoperative good ICG-FI, whereas 10 (22.7%) patients with intraoperative poor or inadequate ICG-FI. Among the 44 patients, the mean operation time was (220.5±44.4) minutes; the median intraoperative blood loss was 20 (20, 45) mL; and the median number of intraoperative lymph node yield was 13.5 (12.0, 18.0). Postoperative complications included AL in 5 patients, with 3 patients having intraoperative good ICG-FI and 2 patients having intraoperative poor ICG-FI; ileus occurred in 1 patient; and anastomotic bleeding occurred in 1 patient. No other complications occurred. There was no significant difference in FMAX, TMAX, and T1/2MAX between the two groups (P>0.05); the curve slope of the NAL group was greater than that of the AL group, and the difference was statistically significant (P<0.05). [Conclusion] ICG-FI technology has a certain application value in laparoscopic radical resection of colorectal cancer and overall surgical safety is good. |
