Near Infrared Fluorescent Guided Surgery for Brain Tumors with Dr. John Y. K. Lee

Dr. Lee is Associate Professor of Neurosurgery and Otolaryngology at the University of Pennsylvania. He has published extensively on fluorescent molecular imaging, and he specializes in minimally invasive neurosurgery including endoscopy and Gamma Knife radiosurgery.

In this video, Dr. Lee describes his five year experience with high dose, delayed indocyanine green (TumorGlowTM aka Second Window IcG) for brain tumors. The technique works best for contrast-enhancing tumors such as high grade gliomas, all brain metastasis, meningiomas, pituitary adenomas and other histologies. The technique has high sensitivity and high positive predictive value with excellent signal to noise as the brain's intact blood-brain ...

Near Infrared Fluorescence Imaging of Lymphatic Disorders with Dr. Miguel Amore, MD, FACS

Lymphatic disorder is a malfunction of the lymphatic system in which fluid, or lymph, does not pass properly through the lymph nodes and lymphatic vessels. The most common lymphatic disease is lymphedema. The earlier lymphedema is treated, the more that can be done to prevent its progression. Near infrared fluorescence is useful to understand early physiopatgological changes of the lymphatic system after primary or secondary damage and that way an early treatment.

Tumor-Targeted Fluorescent Dyes for FGS Edited with Dr. Philip S. Low, MD

Complete surgical resection of all malignant tissue remains the most reliable cure for cancer. To facilitate quantitative removal of all cancer lesions, we have developed low molecular weight ligand-targeted fluorescent dyes that bind to receptors on cancer cells and thereby illuminate tumor tissue without highlighting normal tissue. With the aid of these dyes surgeons have been able to i) find and resect more malignant lesions, ii) detect and remove positive tumor margins, iii) more accurately stage cancer patients, and iv) locate and resect more malignant lymph nodes than was previously possible using standard surgical methods of palpation and visual inspection. ...

Lymph node mapping in Colorectal Cancer Surgery with Dr. Gabriel Liberale

Nodal staging is a major prognostic factor in colorectal cancer (CRC) and is used to determine which patients should receive adjuvant chemotherapy. Sentinel lymph node (SLN) has been reported as the first lymph node (LN) receiving lymphatic drainage from the tumor as a consequence nodal staging of a patient can be predicted through analysis of this SLN. This concept has been applied in malignant melanoma and breast cancer, using peritumoral blue dye injection, where it has become the standard of care allowing to avoid unnecessary lymphadenectomy in node negative (pN0) patients. However, in colon cancer lymphadenectomy is systematically performed. Therefore, ...

The use of ICG in endocrine surgery with Dr. Michael Bouvet, MD, FACS

Indocyanine Green (ICG) is being utilized to identify both normal parathyroid glands during thyroidectomy and also to identify parathyroid adenomas during parathyroidectomy for primary or secondary hyperparathyroidism. The use of ICG allows for assessment of parathyroid perfusion. By using ICG, surgeons may be able to reduce the incidence of hypoparathyroidism following thyroidectomy and also may find it useful to identify parathyroid adenomas. For adrenal surgery, ICG allows identification of the blood supply and venous drainage of the tumor that at times can be challenging. This lecture will provide you a clear understanding of the use and benefits of the use ...

Interests of intra operative ICG Fluorescence in Liver Transplantation Edited

This webinar will present the interest of intra operative NIR fluorescence of ICG in the field of cadaveric liver transplantation. The interest of ICG fluorescence to assess arterial reconstruction of the graft will be emphasized using clinical cases. Our works about qualitative and quantitative liver parenchymal fluorescence enhancement to predict the risk of graft loss will be presented in this webinar

Fluorescence-Guided Surgery of Head and Neck Cancer

Results will be presented from ongoing clinical trials evaluating the ability of fluorescently labeled antibodies to enhance surgical resection in head and neck patients. Additionally, the inherent benefit of the technology will be examined during various stages of the surgical treatment workflow. Individual cases demonstrating patient benefit will be presented. In order to advance the field of fluorescence-guided surgery for oncologic resection, it is critical to investigate all areas of clinical application to maximize patient benefit.

Preventing Postoperative Hypocalcemia in Thyroid Surgery with Fluorescence Visualization of Parathyroid Glands

Dr Fernando Dip will be showing us the results of a study that was recently published. The effectiveness of using near-infrared light (NIRL) intraoperatively for parathyroid gland identification was demonstrated. He will be showing us how the technology can be used in order to decrease the rate of hypocalcemia after thyroidectomies.
