FGS relies on the fluorescence signal emitted by injected substances(fluorophores) after being illuminated by ad hoc laser sources to help guide the surgical procedure and provide the surgeon with real-time visualization of the fluorescent structures of interest that would be otherwise invisible. This review surveys and discusses the most common and emerging clinical applications of indocyanine green(ICG)-based fluorescence in visceral, hepatobiliary and pancreatic surgery. The analysis, findings, and discussion presented here rely on the authors' significant experience with this technique in their medical institutions, an up-to-date review of the most relevant articles published on this topic between 2014 and 2018, and lengthy discussions with key opinion leaders in the field during recent conferences and congresses. For each application, the benefits and limitations of this technique, as well as applicable future directions, are described. The imaging of fluorescence emitted by ICG is a simple, fast,relatively inexpensive, and harmless tool with numerous different applications in surgery for both neoplasms and benign pathologies of the visceral and hepatobiliary systems. The ever-increasing availability of visual systems that can utilize this tool will transform some of these applications into the standard of care in the near future. Further studies are needed to evaluate the strengths and weaknesses of each application of ICG-based fluorescence imaging in abdominal surgery.展开更多

METHODS: This single centre, retrospective observational case series study included data from 121 patients with wAMD (121 eyes) who were diagnosed by indirect ophthalmoscopy, fluorescence fundus angiography (FFA), indocyanine green angiography, and optical coherence tomography. Ranibizumab was injected into the vitreous cavities once per month for 3mo and as needed afterwards. Changes in visual acuity and central foveal thickness (CFT) during the follow-up period were compared, and the mean number of injections over the year was calculated. Patients with one or more adverse events related to the drugs and injections were recorded for further adverse events analysis.RESULTS: The study population included 70 males and 51 females aged between 50 and 87y (mean: 71.32±9.41y). The mean number of injections over the first year was 5±1 (range: 3-9). The mean best-corrected visual acuity by Early Treatment Diabetic Retinopathy Study increased from 43.2±19.3 (95%CI: 39.8-46.7) at baseline to 51.7±20.1 (95%CI: 48.1-55.3), and central foveal thickness (CFT) decreased from 526.5±277.0 μm (95%CI: 476.6-576.4) to 258.2±161.6 μm (95%CI: 229.2-287.3) at 12mo. The differences were statistically significant (P〈0.001). Visual acuity significantly improved in 34.1% of the patients (38 eyes), stabilized in 66.1% of the patients (80 eyes), and significantly decreased in 2.5% of the patients (3 eyes). CFT at baseline was an independent risk factor of decreased CFT and increased visual acuity. None of the patients had severe adverse events during the follow-up period.CONCLUSION: Ranibizumab can effectively control disease progression and improve visual acuity in patients with wAMD. The disease conditions of most patients stabilized 展开更多
