    Abstract:
    OBJECTIVE: To evaluate the use of ultrasonic advanced energy in reducing the occurrence of symptomatic lymphocele and its related complications in laparoscopic extra-peritoneal para-aortic lymphadenectomy in patients with gynecological cancer. STUDY DESIGN: A retrospective cohort study of consecutive patients in a tertiary referral center identified 2 groups of patients, undergoing laparoscopic extra-peritoneal para-aortic lymphadenectomy with or without the use of ultrasonic advanced energy. Surgery time, hospital stay, number of retrieved nodes and lymphocele requiring treatment were studied. Results were also compared between trained and trainee surgeons. RESULTS: 163 patients were scheduled for laparoscopic extra-peritoneal para-aortic lymphadenectomy: 81 treated using bipolar energy (control group: group 1) between August 1999 and January 2005, and 82 treated using ultrasonic advanced energy (study group: group 2) between July 2010 and March 2014. The main indication (90% in group 1, 61% in group 2) was advanced cervical carcinoma (stage IB2 and above). Ultrasonic advanced energy significantly decreased operative time (p=0.001) and intra-operative bleeding (p=0.01) and increased the number of para-aortic nodes retrieved (p=0.02). There was no significant difference in hospital stay or lymphocele requiring treatment (8.6% in group 1, 8.5% in group 2: p=0.98). For senior than for junior surgeons, surgery time was shorter but not significantly (p=0.80) and postoperative lymphocele rates were identical. CONCLUSION: Ultrasonic advanced energy may provide benefit in laparoscopic para-aortic lymphadenectomy, facilitating surgical ergonomics, but did not decrease post-surgery lymphocele.
