Introduction/Background*The objective of this study is to describe the results of patients with endometrial adenocarcinoma in early stages, which have undergone a selective sentinel lymphatic node biopsy (SLNB).

Methodology Retrospective observational descriptive study of patients with endometrial cancer treated by robotic surgery with Da Vinci Xi who underwent SLNB by Indocyanine green staining with ultrastratification using 5 sections separated by 200 microns. Study conducted from April 2019 to June 2020. We included 24 patients with early stages Endometrial adenocarcinoma. The technique for performing BSGC was by diluting 25 mg oc ICG in 5 ml of physiological serum and then 1 ml of this dilution in another 10 ml of serum. Subsequently we administered 1 ml of this solution in the cervix at 3 and 9 o’clock points by introducing a 21G needle, 1 cm deep into the cervix

Result(s)*The sample had a mean age of 61.3 years and a mean BMI of 28.6. In 2 of the cases (8%) the SN were positive even presenting myometrial infiltration <50% and in three of the cases (12.5%) the SN were not identified. SLNs were located in 98% of cases (n: 23) at the level of the obturator fossa and just in one case (2%) at the level of the external iliac artery and vein.

Conclusion*SLNB is an effective technique to assess lymphatic involvement due to adenocarcinoma of the endometrium in early stages.
