Removing in situ and metastasis lesions completely during gynecological surgery is central to reduce the recurrence and death, and the identification of lesions in traditional gynecological surgery often depends on the experience of surgeons. The identification of nerves is often needed in gynecological surgery, such as the obturator nerves in pelvic lymphadenectomy, and the pelvic autonomic nerves in nerve-sparing radical hysterectomy for cervical cancer. Nerve identification also relies heavily on the experience of surgeons. This project aims to realize the identification of lesions and nerves under the navigation of indocyanine green fluorescent imaging, and evaluate the accuracy of fluorescent imaging of lesions and the effectiveness of nerves identification by near-infrared imaging. This project may reduce the recurrence or death caused by residual lesions and postoperative dysfunction caused by nerves injury, thus, improve the survival rate and quality of life for patients with gynecological diseases.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Indocyanine Green Fluorescent Imaging | Experimental | Patients will be intravenously injected ICG (Yichuang Pharmaceutical Limited Liability Company, Dandong, China) at a dose of 2-5 mg per kg of body weight before surgery or 0.25-0.5 mg per kg of body weight during surgery. Then, a NIR imaging systems included the NIR (800-900 nm) and white-light (400-650nm) dual-channel will be used to detect In situ lesions, metastatic lesions, lymph nodes, obturator nerve, pelvic autonomic nerve, etc during surgery according to disease and clinical needs. |

| Intravenous ICG and Real-Time Near-infrared Imaging | Other | Patients will be intravenously injected ICG (Yichuang Pharmaceutical Limited Liability Company, Dandong, China) at a dose of 2-5 mg per kg of body weight before surgery or 0.25-0.5 mg per kg of body weight during surgery. Then real-time near-infrared imaging will be conducted during surgery. |
| Measure | Description | Time Frame |
|---|---|---|
| The value and feasibility of real-time near-infrared imaging in the identification of lesions | Evaluation of the effectiveness of real-time near-infrared imaging in detecting the margin of in situ lesions, whether there is metastasis lesions and whether the metastasis lesions has been completely removed , lymph node metastasis or not during gynecological surgery. The criteria of evaluation is postoperative pathological results and fluorescence intensity of specimen sections measured by laser scanning confocal microscope. | 4 years |
| The value and feasibility of real-time near-infrared imaging in the identification of nerves | Evaluation of the effectiveness of real-time near-infrared imaging in detecting nerves associated with gynecological surgery, including the pelvic autonomic nerves composed of the abdominal aortic plexus, the superior hypogastric plexus, the hypogastric nerves, the pelvic splanchnic nerves, the inferior hypogastric plexus and its branches, obturator nerves, genitofemoral nerve, etc. | 4 years |
