Hysterectomy is one of the most common surgical procedures in gynecology, especially by laparoscopy. Post-operative complications of hysterectomy are numerous and their causes are poorly understood. Indocyanine green is a fluorescent dye that, when exposed to infrared light, makes it possible to visualize the vascularization by fluorescence. The project consists in studying the vascularization of the vaginal cuff after total laparoscopic hysterectomy using the injection of indocyanine green. This is a prospective feasibility study. During the procedure, after performing the hysterectomy, indocyanine green will be injected intravenously into the patient. A fluorescence video of the vaginal cuff will be recorded. The fluorescence of the recorded images will be analyzed by fluorescence analysis software to obtain an objective value of fluorescence. The fluorescence values will be compared to the occurrence or absence of postoperative complications. This is the first study using this imaging technique combined with indocyanine green in this surgery. This study will employ a novel objective sequential fluorescence analysis software that has already proven its effectiveness in digestive surgery. The sequential measurement of the change in fluorescence intensity visualized in the images of laparoscopy will enable the production of vaginal perfusion graphs using a video modeling tool such as the TRACKER software. This software measures the evolution of green levels in a region of interest, from which a time-fluorescence curve can be obtained. The presence of fluorescence will be defined by a fluorescence intensity value of Fmax-Fmin on the graph.
