Intraoperative molecular imaging is a promising new technology with numerous applications in lung cancer surgery. Accurate identification of small nodules and assessment of tumor margins are two challenges in pulmonary resections for cancer, particularly with increasing use of video-assisted thoracoscopic surgery (VATS). One potential solution to these problems is intraoperative use of a fluorescent contrast agent to improve detection of cancer cells. This technology requires both a targeted fluorescent dye that will selectively accumulate in cancer cells and a specialized imaging system to detect the cells...

BACKGROUND: Pulmonary segmentectomy with radical lymphadenopathy has been considered effective to manage small primary lung cancers [1, 2]. This procedure provides the advantages of minimal invasive surgery and is reported sufficient for safe margin. However, segmentectomy is more difficult to be performed than lobectomy because intersegmental plane cannot be detected easily. Several methods have been reported for identifying the actual intersegmental plane [3-7], but the sensitivity of these methods is limited to the lung conditions like patients with emphysematous lung and needed skilled surgeon to perform...

The maintenance of a good surgical view is mandatory in video-assisted thoracoscopic surgery (VATS). For routine segmentectomy, it is necessary to re-inflate the lung in order to identify the intersegmental borders. However, such re-inflation can occasionally obstruct the surgical view and can lead to prolongation of operation time, particularly in the context of VATS. Infrared thoracoscopy( IRT) with indocyanine green (ICG) is a new method of evaluating lung perfusion. There are 2 methods in IRT. One is based on ICG absorption, and the other is based on ICG fluorescence...

Surgery is the most effective method to cure patients with solid tumors. New techniques in near-infrared (NIR) cancer imaging are being used to identify surgical margins and residual tumor cells in the wound. Our goal was to determine the optimal time and dose for imaging solid tumors using Indocyanine Green. Syngeneic murine flank tumor models were used to test NIR imaging of ICG at various doses ranging from 0 to 10 mg/kg. Imaging was performed immediately after injection and up to 72 hours later. Biodistribution in the blood and murine organs were quantified by spectroscopy and fluorescence microscopy...

BACKGROUND: The use of near-infrared (NIR) fluorescence imaging with indocyanine green (ICG) for sentinel lymph node (SN) mapping has been investigated in lung cancer; however, this has not been fully adapted for minimally invasive surgery (MIS). The aim of our study was to develop a minimally invasive SN mapping integrating pre-operative electro-magnetic navigational bronchoscopy (ENB)-guided transbronchial ICG injection and intraoperative NIR thoracoscopic imaging. METHODS: A NIR thoracoscope was used to visualize ICG fluorescence...

PURPOSE: In most general thoracic operations performed via standard posterolateral thoracotomy, such as for descending aortic aneurysms and lung cancer, the latissimus dorsi (LD) muscle is divided. However, division of the LD can hamper reconstructive surgery because the initial operation creates unstable blood flow to the divided LD. We conducted this study to assess blood flow in a divided distal LD muscle flap using intraoperative indocyanine green-fluorescence angiography (ICG-FA) with the Hyper Eye Medical System(®) (Mizuho Medical Co...

To achieve precise and sensitive detection of chemotherapy-resistant hepatoblastoma pulmonary metastases, we performed surgery using indocyanine green (ICG) fluorescence imaging navigation. Lung metastasectomies were performed in 10 patients aged from 1 to 11 years. ICG (0.5 mg/kg) was injected intravenously 24 h before the operation. After a thoracotomy had been performed, a 760-nm infrared ray was applied to the lung using a generator and the 830-nm evoked fluorescence was collected and visualized on a real-time display...

Near-infrared dyes can be used as theranostic agents in cancer management, based on their optical imaging and localized hyperthermia capabilities. However, their clinical translatability is limited by issues such as photobleaching, short circulation times, and nonspecific biodistribution. Nanoconjugate formulations of cyanine dyes, such as IR820, may be able to overcome some of these limitations. We covalently conjugated IR820 with 6 kDa polyethylene glycol (PEG)-diamine to create a nanoconjugate (IRPDcov) with potential for in vivo applications...

Infrared thoracoscopy with indocyanine green (ICG) is a new method of evaluating lung perfusion. We succeeded in visualizing lung emphysematous lesions and intersegmental borders using infrared thoracoscopy with ICG in animals, and within clinical investigations. There are 2 methods in infrared thoracoscopy. One is the 2-wavelength method, and the other is the 1-wavelength method. The 2- wavelength method is based on ICG absorption, and the 1-wavelength method is based on ICG fluorescence. The 2-wavelength method is superior for the clarity of images...

BACKGROUND: Over 80,000 people undergo pulmonary resection for a lung nodule in the United States each year. Small nodules are frequently missed or difficult to find despite preoperative imaging. We hypothesized that near-infrared (NIR) imaging technology could be used to identify and locate lung nodules during surgery. METHODS: We enrolled 18 patients who were diagnosed with a pulmonary nodule that required resection. All patients had a fine-cut 1-mm computed tomography scan preoperatively...

INTRODUCTION: Defining tumor from non-tumor tissue is one of the major challenges of cancer surgery. Surgeons depend on visual and tactile clues to select which tissues should be removed from a patient. Recently, we and others have hypothesized near-infrared (NIR) imaging can be used during surgery to differentiate tumors from normal tissue. METHODS: We enrolled 8 canines and 5 humans undergoing cancer surgery for NIR imaging. The patients were injected with indocyanine green (ICG), an FDA approved non-receptor specific NIR dye that accumulates in hyperpermeable tissues, 16-24 hours prior to surgery...

We report the design, characterization, and validation of an optimized simultaneous color and near-infrared (NIR) fluorescence rigid endoscopic imaging system for minimally invasive surgery. This system is optimized for illumination and collection of NIR wavelengths allowing the simultaneous acquisition of both color and NIR fluorescence at frame rates higher than 6.8 fps with high sensitivity. The system employs a custom 10-mm diameter rigid endoscope optimized for NIR transmission. A dual-channel light source compatible with the constraints of an endoscope was built and includes a plasma source for white light illumination and NIR laser diodes for fluorescence excitation...

Fluorescence guided surgery (FGS) is a developing field of surgical and oncologic research. Practically, FGS has shown useful applications in urologic surgery, benign biliary surgery, colorectal cancer liver metastasis resection, and ovarian cancer debulking. Most notably in in cancer surgery, FGS allows for the clear delineation of cancerous tissue from benign tissue. FGS requires the utilization of a fluorescent contrast agent and an intraoperative fluorescence imaging device (IFID). Currently available IFIDs are expensive, unable to work with multiple fluorophores, and can be cumbersome...
