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

Abstract

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. 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. 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. A specialist minimal access team can safely and reliably reproduce this technique for sentinel lymph node excision.
