Novel Exoscope System for 5-ALA Fluorescence-Guided Surgery for Gliomas

2019-08-18 20:09:36 | BioPortfolio


5-ALA and the Orbeye surgical microscope are U.S. Food and Drug Administration (FDA) approved products. For this study, the Orbeye microscope imaging system is being used with special filters to visualize 5-ALA fluorescence. The FDA currently permits the use of these filters. The purpose of this study is to collect medical information before, during, and after standard treatment in order to better understand how to make this type of procedure accessible to patients.

This study is also being conducted to determine if use of the Orbeye equipped with these special filters improves the ability of the surgeon to remove brain tumors.

Medical and Biotech [MESH] Definitions

The local implantation of tumor cells by contamination of instruments and surgical equipment during and after surgical resection, resulting in local growth of the cells and tumor formation.

A compound produced from succinyl-CoA and GLYCINE as an intermediate in heme synthesis. It is used as a PHOTOCHEMOTHERAPY for actinic KERATOSIS.

An enzyme that catalyzes the formation of porphobilinogen from two molecules of 5-aminolevulinic acid. EC

The edges of tissue removed in a surgery for assessment of the effectiveness of a surgical procedure in achieving the local control of a neoplasm and the adequacy of tumor removal. When the margin is negative or not involved by tumor (e.g., CANCER) it suggests all of the tumor has been removed by the surgery.
