Cavitron Ultrasonic Surgical Aspirator in Laparoscopic Nerve-Sparing Radical Hysterectomy: A Pilot Study

Int J Gynecol Cancer. 2016 Mar;26(3):594-9. doi: 10.1097/IGC.0000000000000628.

Abstract

Objective: Pelvic autonomic nerve preservation during radical hysterectomy for cervical cancer has become a priority in recent years. This pilot study was undertaken to evaluate laparoscopic nerve-sparing radical hysterectomy (L-NSRH) using the Cavitron Ultrasonic Surgical Aspirator (CUSA) in women with cervical cancer.

Methods: Patients with stage IB1 or IIA1 cervical cancer underwent L-NSRH with pelvic lymphadenectomy. The patients were randomly assigned to receive L-NSRH using a CUSA (CUSA group; n = 24) or using other techniques (non-CUSA group; n = 21). Recovery of bladder function (indwelling catheter time and time to spontaneous voiding) blood loss, duration of hospital stay, lymph node harvesting, and postoperative complications were compared between the 2 groups. Patients were followed for up to 3 years to determine the maintenance of effect.

Results: All patients underwent L-NSRH successfully. Intraoperative blood loss was significantly less in the CUSA than in the non-CUSA group (P = 0.005). Length of hospital stay (P = 0.006) and indwelling catheter time (P = 0.008) were both significantly reduced in the CUSA group compared with that in the non-CUSA group. The spontaneous voiding rate 10 days postoperatively was 95.8% with CUSA and 85.7% with non-CUSA techniques. Two patients developed postoperative complications in the CUSA group as did 3 patients in the non-CUSA group. These were cases of lymphocyst formation or urinary tract infection.

Conclusions: Laparoscopic nerve-sparing radical hysterectomy using CUSA was safe and feasible in patients with cervical cancer. Our results provide initial evidence that L-NSRH using CUSA preserves pelvic autonomic nerve function.
