Laparoendoscopic Single-site Surgery for Comprehensive Staging of Early Ovarian Cancer

To demonstrate the procedure and suspension skills of laparoendoscopic single-site (LESS) staging surgery with infrarenal para-aortic lymphadenectomy for early-stage ovarian cancer.

A 45-year-old woman presented with a pelvic mass on gynecologic examination and a serum cancer antigen 125 level of 5910 U/mL (normal = <35 U/mL). A computed tomographic scan revealed a mixture of solid and cystic components (70 × 77 × 71 mm) arising from the right ovary and characterized by the "ovarian vascular pelvic" sign. Clinically early-stage ovarian cancer was suspected. Subsequently, LESS staging surgery was performed by an experienced surgeon in our department.

The surgery lasted 280 minutes, and the volume of blood loss was 50 mL; there were no intra- or postoperative complications. We "hid" the incision perfectly for cosmetic purposes. The histopathologic findings supported high-grade serous ovarian cancer of the right ovary with the left fallopian tube involved as well. In addition, a total of 34 negative pelvic and 18 negative para-aortic lymph nodes were identified, and a stage of IIA was diagnosed as a result.

We performed an LESS staging surgery for early-stage ovarian cancer successfully. Our video shows that the LESS approach provided feasible, cosmetic, and safe access among the selected malignant gynecologic surgery. Therefore, we have experienced that the effective suspension was an auxiliary measure for LESS lymphadenectomy. In addition, compared with multiport laparoscopy, the LESS approach could provide easier access to infrarenal para-aortic regions; furthermore, it was safe and quick to extract an unknown sample.
