Usefulness of extraperitoneal laparoscopic paraaortic lymphadenectomy for lymph node recurrence in gynecologic malignancy.

ABSTRACT

OBJECTIVE: The aim of this study was to evaluate the safety and feasibility of extraperitoneal laparoscopic paraaortic lymphadenectomy for suspected lymph node recurrence of gynecological cancers. DESIGN: Descriptive study. SETTING: Unit of Gynecologic Oncology of an acute-care teaching hospital in Barcelona, Spain. POPULATION Between December 2002 and October 2007, eight women underwent extraperitoneal laparoscopic paraaortic lymphadenectomy for suspected lymph node recurrence, detected by magnetic resonance image (MRI), computed tomography (CT) scan or 18F-fluorodeoxyglucose positron emission tomography (PET) scanning. The suspicious nodes were removed through an extraperitoneal laparoscopic approach. RESULTS: The median age of patients was 66.5 years (range 54-74). The median operating time was 157.5 minutes (range 120-240). The median blood loss was 112.5 mL (range 50-150). The mean nodal yield was 9.4+/-4.72 (range 1-16). There were no intraoperative or postoperative complications. The median hospital stay was two days. Histological examination revealed metastasis in seven of eight patients. CONCLUSIONS: The extraperitoneal laparoscopic paraaortic lymphadenectomy for lymph node recurrence of gynecological cancers is a safe and feasible procedure which should be considered where there is isolated involvement of retroperitoneal lymph nodes. This procedure is a minimally invasive technique that allows an excellent approach to the paraaortic lymph nodes.
