The Advantage of Pinpoint Camera System With Indocyanine Green for Sentinel Lymph Node Micrometastasis Detection in Low Risk Endometrial Cancer

Abstract

Background/Aim: This report outlines our experience in the management of 10 cases of low-risk endometrial cancer with Indocyanine Green for sentinel lymph node (SLN) mapping using the Pinpoint 30-degree 4K S1 SPY real-time camera system (Stryker). This system offers simultaneous, real-time, high-definition white light and fluorescence imaging through a single laparoscope, without the need to change camera filters. Patients and Methods: In our retrospective case series we included all endometrioid endometrial cancers of grade G1 and pre-operative radiological staging FIGO 1A reported on magnetic resonance imaging (MRI) that were treated laparoscopically from October 2019 to April 2020. Results: Bilateral sentinel lymph node excision was achieved in 9 out of 10 cases. In one patient, one sentinel lymph node featuring a micrometastasis of <2 mm was identified. Conclusion: A specialist minimal access team can safely and reliably reproduce this technique for sentinel lymph node excision.
