“…However, quantitative analysis of colonic perfusion is still rare in surgical practice. In recent quantitative studies, F MAX , T 1/2MAX , and fluorescence slope were correlated with bowel viability or anastomotic leakage [ 21 – 23 ]. A delayed T 1/2MAX in graphs of jejunal perfusion reflects insufficient blood flow and may increase the possibility of postoperative ischemia [ 21 ].…”

In study of 112 patients in Japan, F MAX and fluorescence slope were analyzed as predictors of anastomotic leakage, but T 1/2MAX was not a significant factor [ 23 ].…”

“…As the introduction of NIR fluorescence imaging, 11 clinical studies reported the use of ICG as a NIR fluorescent agent in evaluation of the esophagogastric anastomosis . One study compared the anastomotic leakage rate in perfusion detection both with and without the use of ICG fluorescence imaging, which resulted in reducing the rate from 20% to 0% .…”

Near‐infrared (NIR) fluorescence imaging is gaining clinical acceptance over the last years and has been used for detection of lymph nodes, several tumor types, vital structures and tissue perfusion. This review focuses on NIR fluorescence imaging with indocyanine green and methylene blue for different clinical applications in abdominal surgery with an emphasis on oncology, based on a systematic literature search. Furthermore, practical information on doses, injection times, and intraoperative use are provided.

“…We evaluated the flow speed of ICG fluorescence in the gastric conduit wall, in difference to other investigators who have previously assessed the intensity of ICG fluorescence for quantitative analysis. [27,28] When compared with our assessment, their methods may differentiate between inflow impairment and outflow impairment of the gastric conduit wall. In our study, the flow speed of ICG fluorescence in the gastric conduit wall showed no correlation with connection of right and left gastroepiploic arteries and congestion at the tip of the gastric conduit, but had high sensitivity and specificity to predict anastomotic leakage; therefore, our method could evaluate the comprehensive blood flow including the inflow and outflow of the gastric conduit wall.…”

Anastomotic leakage is considered as an independent risk factor for postoperative mortality after esophagectomy, and an insufficient blood flow in the reconstructed conduit may be a risk factor of anastomotic leakage. We investigated the clinical significance of blood flow visualization by indocyanine green (ICG) fluorescence in the gastric conduit as a means of predicting the leakage of esophagogastric anastomosis after esophagectomy.Forty patients who underwent an esophagectomy with gastric conduit reconstruction were prospectively investigated. ICG fluorescence imaging of the gastric conduit was detected by a near-infrared camera system during esophagectomy and correlated with clinical parameters or surgical outcomes.In 25 patients, the flow speed of ICG fluorescence in the gastric conduit wall was simultaneous with that of the greater curvature vessels (simultaneous group), whereas in 15 patients this was slower than that of the greater curvature vessels (delayed group). The reduced speed of ICG fluorescence stream in the gastric conduit wall was associated with intraoperative blood loss (P = 0.008). Although anastomotic leakage was not found in the simultaneous group, it occurred in 7 patients of the delayed group (P < 0.001). A flow speed of ICG fluorescence in the gastric conduit wall of 1.76 cm/s or less was determined by a receiver operating characteristic (ROC) curve, identified as a significant independent predictor of anastomotic leakage after esophagectomy (P = 0.004).This preliminary study demonstrates that intraoperative evaluation of blood flow speed by ICG fluorescence in the gastric conduit wall is a useful means to predict the risk of anastomotic leakage after esophagectomy.
