Summary: This systematic review of near-infrared fluorescence imaging parameters for assessing tissue perfusion demonstrates the heterogeneity of these parameters in their correlation to perfusion, with time-related parameters appearing superior in a clinical setting.

Summary: This study aimed to identify objective quantified bowel perfusion patterns in patients undergoing colorectal surgery using a standardized imaging protocol. The study found three different perfusion patterns and highlighted the poor-moderate inter-observer agreement of the subjective interpretation of the fluorescence signal. Objective quantification is needed to assess bowel perfusion.

Summary: This pilot study aimed to evaluate the feasibility and potential of using hyperspectral imaging and fluorescence imaging with indocyanine green to measure gastric conduit perfusion during esophagectomy. The results showed that both imaging techniques were complementary in determining the ideal anastomotic position and may contribute to better surgical outcomes.

Summary: This study aimed to evaluate the usefulness of indocyanine green fluorescence imaging (ICG-FI) in assessing intestinal vascular perfusion in patients undergoing intracorporeal anastomosis (IA) for colon cancer surgery. The results showed that ICG-FI can effectively detect poor anastomotic perfusion and help prevent anastomotic leakage.

Summary: Intraoperative monitoring of tissue perfusion is crucial for optimizing surgery and reducing postoperative complications. Indocyanine green (ICG) fluorescence angiography is commonly used, but imaging photoplethysmography (iPPG) shows potential for contactless assessment. This study compared iPPG and ICG-fluorescence systems in eight gastrointestinal surgeries and found that iPPG provides quantitative assessment of blood perfusion in good agreement with ICG-fluorescence imaging.

Summary: ICG fluorescent imaging can effectively assess the blood supply of transposed jejunum. When T-1/2max value > 5.35 s, the possibility of the incidence rate of anastomotic leakage or transposed jejunum necrosis increases.

Summary: This study aimed to determine the applicability and usefulness of using ICG-FI to evaluate intestinal perfusion in a porcine model of mesenteric ischemia. The results showed that ICG-FI can reliably detect differences in perfusion after different durations of ischemia, making it an encouraging method for assessing intestinal perfusion intraoperatively.

Summary: Anastomotic leakage is a feared complication of colorectal surgery and is strongly associated with tissue perfusion. Indocyanine green fluorescence angiography (ICG-FA) is an innovative technique that allows visualization of anastomotic perfusion. Several clinical trials have shown promising results in reducing the risk of anastomotic leakage with ICG-FA, but further large-scale studies are needed. The current evaluation method of ICG-FA is subjective, and objective evaluation methods using quantitative parameters are being investigated. Standardized and high-quality studies are warranted to validate the utility of ICG-FA in colorectal surgery.

Summary: This study aims to investigate the application of laser speckle contrast imaging (LSCI) in real-time surgical visualization of tissue blood flow. By combining with indocyanine green (ICG) fluorescence, LSCI can improve the accuracy and precision of perfusion detection in tissues compared to using ICG alone.

Summary: This study highlights the challenges in quantifying NIR fluorescence imaging for perfusion analysis through the description of four patients with possible compromised bowel perfusion. Different fluorescence dynamics patterns were observed in affected bowel segments compared to unaffected reference segments, suggesting difficulties in interpreting uncorrected fluorescence signals. Real-time quantification and standardization of NIR fluorescence perfusion imaging could potentially assist surgeons in making informed treatment decisions.

Summary: The assessment of ovarian perfusion in patients with ovarian torsion is crucial for surgical management. Currently, surgical decisions are based on subjective impressions. Intraoperative indocyanine green (ICG) angiography has shown to reflect tissue perfusion and impact surgical procedures. Although there is limited data, the use of ICG in the surgical treatment of ovarian torsion appears feasible and safe. Further evaluation is needed to determine the extent to which it reduces the necessity for oophorectomy.

Summary: The study aims to determine the feasibility of real-time continuous perfusion assessment using ICG. It was found that by using a novel ICG dosing regimen and quantification software, it is possible to monitor organ perfusion in the abdomen. However, there was significant variation in fluorescence intensity between organs and between the same organ in different subjects using a fixed weight-adjusted dosing regimen with the same camera setting and placement.

Summary: Intraoperative Q-ICG shows promise for clinical application, with inflow parameters such as slope and T(1/2)max demonstrating superior performance in clinical settings. However, most studies have focused on post-operative analyses, and future research should emphasize methodological approaches outlined in this review, including the use of inflow parameters, mass-adjusted ICG dosing, and fixed camera positioning.
