The aim of this study was to analyze the first 100 cases of planned laparoscopic pelvic and paraaortic lymph node dissection (LND) done for staging of gynecologic cancers. The goal of the study was to assess prognostic factors for conversion to laparotomy and document complications.


A retrospective review of patients who had planned laparoscopic bilateral pelvic and bilateral paraaortic LND for staging of their gynecologic cancer was performed. Patients were identified by our institutional database and data were collected by review of their medical records. Data were obtained regarding demographics, stage, histology, length of stay, and procedural information including completion rates, operating room time, estimated blood loss, assistant, lymph node count, and complications. Associations between variables were analyzed using Student t tests, analysis of variance, and chi(2) testing (Excel v7.0).


A total of 103 patients were identified from 12/15/95 to 8/28/00. Demographics included mean age of 66.2 (25-92) and mean Quetelet index (QI) of 30.8 (15.9-56.1). A total of 34/103 (33.0%) had > or =1 previous laparotomy. Ninety-five patients had endometrial cancer and 8 had ovarian cancer. Eighty-six of 103 (83.5%) were stage I or II. The length of stay was shorter for those who had laparoscopy than for those who needed conversion to laparotomy (2.8 vs 5.6 days, P < 0.0001). Laparoscopy was completed in 73/103 (70.9%) of the cases. Completion rates were 62/76 (81.6%) with QI < 35 vs 11/27 (40.7%) with QI > or = 35, P < 0.001. Significantly more patients had their laparoscopy completed when an attending gynecologic oncologist was the first assistant compared to a fellow or a community obstetrician/gynecologist (92.9%, 69.0%, 64.5%, P < 0.0001). The top three reasons for conversion to laparotomy were obesity, 12/30 (29.1%), adhesions, 5/30 (16.7%), and intraperitoneal disease, 5/30 (16.7%). Pelvic, common iliac, and paraaortic lymph node counts did not differ when compared to those of patients who had conversion to laparotomy (18.1, 5.1, 6.8 vs 17.3, 5.7, 6.8, P = ns). Complications included 2 urinary tract injuries, 2 pulmonary embolisms, and 6 wound infections (all in the laparotomy group). Two deaths occurred, 1 due to a vascular injury on initial trocar insertion and 1 due to a pulmonary embolism after a laparotomy for bowel herniation through a trocar incision.


Laparoscopic bilateral pelvic and paraaortic LND can be completed successfully in 70.9% of patients. Age, obesity, previous surgery, and the need to perform this procedure in the community were not contraindications. Advantages include a shorter hospital stay, similar nodal counts, and acceptable complications.
