To describe our experience with extraperitoneal lymph node staging in gynecologic oncology. The extraperitoneal approach was performed to assess the lymph node histology in patients with gynecologic malignancies. The nodes are approached froma lateral approach after dissecting open the extraperitoneal space bluntly and with insufflation. Bilateral aortic nodes are taken from a left- sided or right- sided approach depending on the patient’ s characteristics. Forty- six patients underwent this procedure over a 2.5- year period. Thirty- seven patients had cervical cancer. The median BMI was 27.1 (17.7- 38.1). The median lymph node yield was 14 (0- 60). Two patients had disruption of the peritoneumsuch that the aortic lymphadenectomy had to be completed transperitoneally. No patients required laparotomy. No patients required transfusion. This technique permits histologic evaluation of the retroperitoneal nodes with minimal risk of intraabdominal adhesions. Recovery is rapid and further therapy can be prescribed shortly. The data on the nodes can assist in treatment planning.
