“…Intraureteral ICG was subsequently detected using near-infrared laser fluorescence technology (Firefly®). This preliminary report was followed by similar reports by Ryu et al, Kanabur et al, and Mandovra et al, using the same technique for applying the intraureteral ICG dye with the same promising results [4,7,8] .…”

Aim: To describe the currently available evidence regarding the efficacy and safety of intraureteral indocyanine green (ICG) instillation for ureteral identification in colorectal surgery. Methods: Systematic search of PubMed and Scopus through May 2022 reported according to PRISMA 2020. Studies reporting treatment of patients < 18 years, with unavailable full-text, reviews, editorials, animal studies, and studies including non-colorectal operations were excluded. Results: Seven retrospective studies, published between 2020 and 2022, were identified, in which 142 patients (43% females) were evaluated, of which three were undertaken in the USA, two in Japan, and two in India. The most common indications for surgery were cancer in 58 patients (41%) and diverticular disease in 52 patients (36.6%). Most patients involved underwent robotic surgery (70%), while the remaining patients had laparoscopic surgery. The intraoperative ureteral injury was reported in one patient, while adverse effects (mainly transient hematuria) were reported in 10% of the study population (14 patients). The use of intrauretal ICG prolonged surgery by a median of 12.8 minutes. Conclusion: Intraoperative visualization of ureters using ICG in colorectal surgery is safe and effective, according to the results of this study. However, this technique still bears the potential disadvantages of ureteral catheterization. Research is focusing on future dyes combining the ICG properties with renal excretion to minimize the need for stents. Further comparative studies are needed to reach safe results.

“…The ureters are retroperitoneal structures that can be easily damaged during the dissection of the colon or rectum, especially in complicated surgeries, causing extensive inflammation and the need for re-operations. There are reports in the literature regarding ICG imaging utilization for intraoperative ureteral identification [ 30 , 31 , 32 , 33 , 34 , 35 , 36 ]. This method involves cystoscopic ureteral stenting and the injection of ICG dye through the stent into each ureter.…”

Background: Indocyanine green (ICG) imaging has been increasingly used for intraoperative guidance in colorectal surgery over the past decade. The aim of this study was to review and organize, according to different type of use, all available literature on ICG guided colorectal surgery and highlight areas in need of further research and discuss future perspectives. Methods: PubMed, Scopus, and Google Scholar databases were searched systematically through November 2022 for all available studies on fluorescence-guided surgery in colorectal surgery. Results: Available studies described ICG use in colorectal surgery for perfusion assessment, ureteral and urethral assessment, lymphatic mapping, and hepatic and peritoneal metastases assessment. Although the level of evidence is low, results are promising, especially in the role of ICG in reducing anastomotic leaks. Conclusions: ICG imaging is a safe and relatively cheap imaging modality in colorectal surgery, especially for perfusion assessment. Work is underway regarding its use in lymphatic mapping, ureter identification, and the assessment of intraperitoneal metastatic disease.

“…Using a near-infrared ray fluorescent ureteral catheter (NIRFUC) and indocyanine green, Ryu [33] and Gila-Bohorquez [34]investigated the utility of fluorescence ureter and vessel navigation (ICG). The conclusions of the study was that fluorescence navigation of vessels and the ureter is feasible in laparoscopic LLND and may increase patient safety.…”

This review looks at the use of indocyanine green (ICG) in colorectal surgery, from a quantitative point of view. The main benefits of the ICG technique in colorectal surgery, can be summarized as follows: a)in the realization of the intraoperative fluorescence angiography as an adjuvant in the process of anastomosis, b)in the fluorescence-guided detection of lymph node metastases in colorectal cancer and, also, the sentinel lymph node technique, which was proven better than formal methods in some studies, c) marking with positive fluorescence a liver nodule as small as "just" 200 tumor cells, d) offering assistance in the diagnosis of a fistula, e)in the possibility to be used for tumor tattooing also, f)providing help in maintaining a clean surgical field and preventing wound infection in abdominoperineal resection. Apart from the qualitative intraoperative use of ICG, the method can be employed in association with quantitative methods, such as maximum intensity, relative maximum intensity, and various parameters of the inflow (time-to-peak, slope, and t1/2max), this latter category being more significantly associated with anastomotic leakage.
