Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study was designed to clinically evaluate the functionality of an prototype of our near-infrared fluorescence device named Easy Light. In brief, this device is an open-field handheld wireless fluorecence imaging system that allows real-time visualization of fluorescent dyes such as indocyanine green (ICG) using smartphones and tablets. The handheld is a rechargeable device responsible for excitation of the operative field with infra-red lighting and for capturing the fluorescence emitted by de fluorescent dye to be visualized via wi-fi in the smartphones and tablets using a pre-installed application software. Following the standards of near-infrared fluorescence for detection of sentinel lymph nodes in gynecological malignancies, the hypothesis was the identification of sentinel lymph nodes after lymphatic mapping by interstitial indocyanine green injection in the cervix was feasible with the use of our device named Easy Light.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Sentinel Lymph Node Biopsy

Sentinel lymph node biopsy by indocyanine green (ICG) fluorescent dye technique, using a prototype of the Easy Light device. Lymph node dissection in each hemipelvis should be performed as standard if no sentinel lymph node is detected. Decision of proceeding with complementary lymph node dissection after sentinel lymph node detection is a surgeon decision, according to his/her usual practice.
