Purpose The aim was to assess and compare perioperative parameters in two groups of patients treated by different laparoscopic techniques of lymph node dissection (LND) for gynecologic cancer. Patients and methods Between October 2015 and October 2017, 59 consecutive women with microinvasive cervical cancer (N=5) or clinical stage I endometrial cancer (N=54) underwent laparoscopic LND during a primary staging procedure using an electrosurgery (ELC) or ultrasonic (US) operative technique. The two groups were compared for perioperative outcomes. Differences between the two groups were determined by the Wilcoxon’s rank-sum test. Results Laparoscopic LND and other staging procedures were completed successfully in 58 (98.3%) women. There were no statistically significant differences between the groups regarding preoperative outcomes (operation time, time for LND, blood loss, hospital stay, and complications), but there was a significant difference (P=0.0008) in the number of lymph nodes harvested: a mean of 13.7 in the ELC group and 17.5 in the US group. The pathologists found that the reading of histology slides was easier after US dissections because of the greater depth of thermal injury in the lymphatic tissue in ELC group. Conclusion The US operative technique ensures efficient coagulation, cutting, dissection, and grasping for laparoscopic LND in patients with cervical and endometrial cancer.
