项目摘要

Abstract The primary liver cancer including intrahepatic bile duct cancer pose significant global burden of illness with increasing incidence and mortality in US and around the world. Surgery remains the most effective form of treatment. However, surgical complication rates for medium to high complexity hepatectomies persist in 30-40% range even in highly skilled hands and at high volume centers. The critical challenges appear to be attributable to navigating liver parenchymal dissection, where size of resection surface, associated with blood loss and missed bile leaks from the liver parenchyma, and prolonged operative time during dissection pose significant obstacle. In this research, we propose to develop an upgraded laparoscopic imager for deeper biliary-specific fluorescent imaging using a short-wave infrared (SWIR) sensor and high-definition RGB color vision, and to test the utility of our multimodal laparoscopic imaging technique in liver surgery throughout preclinical swine studies. The clear anatomic display of intrahepatic critical structures and functional physiology will make the hepatic dissection safer and more efficient for any liver resection. The goal of this 1-year research is to develop and evaluate the novel biliary-specific fluorescence and laparoscopic vision/display through the following specific aims; Aim1: To develop a formfactor SWIR camera system for fluorescence image-guided laparoscopy; Aim 2: To validate the usefulness of the developed new vision platform in preclinical animal studies.

摘要包括肝内胆管癌在内的原发性肝癌给全球带来了巨大的疾病负担。随着美国和世界各地发病率和死亡率的增加。手术仍然是最有效的治疗的形式。然而，中到高复杂性肝切除术的手术并发症发生率坚持30%-40%的范围，即使是在高技能的手和高产量的中心。面临的严峻挑战似乎是由于导航肝实质剥离，其中切除表面的大小，与失血和漏出肝实质胆汁有关，手术时间延长。解剖过程中的时间构成了严重的障碍。在这项研究中，我们建议开发一种升级的腹腔镜成像仪，用于更深层次的胆道特异成像。使用短波红外(SWIR)传感器和高清晰度RGB色觉的荧光成像，并测试我们的多模式腹腔镜成像技术在整个肝脏手术中的实用性临床前猪研究。肝内重要结构和功能的清晰解剖显示生理学将使任何肝脏切除手术更安全、更有效。的目标是这项为期一年的研究是为了开发和评价新型胆道特异性荧光和腹腔镜通过以下具体目标进行视觉/显示；目标1：开发FormFactor SWIR相机用于荧光图像引导的腹腔镜术系统；目标2：验证开发了临床前动物研究的新视觉平台。
