Study of the Vascularization of the Vaginal Slice After Total Laparoscopic Hysterectomy, Using Indocyanine Green Injection.

To perform this study, the patient will undergo a preoperative consultation with a senior surgeon and an anesthetist from the department to schedule the surgical procedure and discuss potential inclusion in the protocol. Day before the surgery : The patient will give an informed and written consent and will be enrolled in the study. The day of the intervention : The planned surgical procedure will be performed as initially scheduled by the surgeon (total hysterectomy). The difference from standard care is that during the intraoperative period, at the end of the procedure, the patient will receive a diluted bolus of indocyanine green (25 mg in 10 ml of 5% glucose solution), at a dose of 0.2 mg/kg. Subsequently, the laparoscopic camera system will be switched to an infrared camera system to visualize intra-abdominal fluorescence using the trocars used during the surgery. A video recording sequence of the vaginal cuff, lasting two to five minutes, starting from the moment of the indocyanine green injection will be collected by the investigator. The collected images will be analyzed using the TRACKER software (Douglas Brown, Open Source Physics, Boston MA, USA). Postoperative period : A postoperative consultation will take place between 3 and 8 weeks after the surgery with one of the senior physicians from the department. Postoperative progress and early complications (dehiscence, cuff infection, abscess, or hematoma) will be documented, along with anatomopathological examination data and the final diagnosis. The postoperative follow-up will remain consistent with the usual protocol following this procedure. The protocol does not involve any additional visits, thus no potential extra coast.
