Tumor Identification

Fluorescent properties of indocyanine green (ICG) for hepatic tumor identification and features have been recently studied. The aim is to review the published data on the use of ICG enhanced fluorescence surgery during liver resection. A systematic search of literature was performed using MEDLINE, EMBASE, Cochrane and Web of Science libraries. For all eligible studies, the following data were extracted: study design, number of cases, management of indocyanine green (dose, time and method of administration), type of surgery, outcome variables, false positive and accuracy value, if reported. For statistical analysis, it was considered significant P<0.05, when published. 19 articles were fully analyzed and data were extracted. A total of 718 cases were globally analyzed as study group. No side effects of ICG were reported in any articles. 12 prospective observational, 1 randomized and 2 case-control studies were found. Three case reports and one experimental on animal model were also included. Detection of superficial lesions, segmental staining, biliary anatomy investigation (biliary leakage detection, biliary tree anatomy) were the main clinical application of fluorescence liver guided surgery. The overall quality of the data currently available is limited but the role of fluorescence guided liver surgery seems promising.

Abstract Background The aim of this systematic review was to identify all methods to quantify intraoperative fluorescence angiography (FA) of the gastrointestinal anastomosis, and to find potential thresholds to predict patient outcomes, including anastomotic leakage and necrosis. Methods This systematic review adhered to the PRISMA guidelines. A PubMed and Embase literature search was performed. Articles were included when FA with indocyanine green was performed to assess gastrointestinal perfusion in human or animals, and the fluorescence signal was analysed using quantitative parameters. A parameter was defined as quantitative when a diagnostic numeral threshold for patient outcomes could potentially be produced. Results Some 1317 articles were identified, of which 23 were included. Fourteen studies were done in patients and nine in animals. Eight studies applied FA during upper and 15 during lower gastrointestinal surgery. The quantitative parameters were divided into four categories: time to fluorescence (20 studies); contrast-to-background ratio (3); pixel intensity (2); and numeric classification score (2). The first category was subdivided into manually assessed time (7 studies) and software-derived fluorescence–time curves (13). Cut-off values were derived for manually assessed time (speed in gastric conduit wall) and derivatives of the fluorescence–time curves (Fmax, T1/2, TR and slope) to predict patient outcomes. Conclusion Time to fluorescence seems the most promising category for quantitation of FA. Future research might focus on fluorescence–time curves, as many different parameters can be derived and the fluorescence intensity can be bypassed. However, consensus on study set-up, calibration of fluorescence imaging systems, and validation of software programs is mandatory to allow future data comparison.
