Abstract

Objective: Multiple reports suggest that laparoendoscopic single-site surgery is technically feasible, safe, and effective in treating a variety of gynecological disease processes. The study purpose was to assess the feasibility and safety of a novel robotic single-site platform (R-LESS) for the surgical treatment of benign and malignant gynecological conditions.

Study design: A single-institution, prospective analysis of 40 women treated with R-LESS on the gynecology and gynecological oncology services from June 2013 through March 2014. Women undergoing hysterectomy or adnexal surgery for either a benign or malignant gynecological condition were offered robotic single-site surgery during the study period of June 1, 2013, through April 1, 2014. Patients underwent surgery through a single 2.5-3.0 cm umbilical incision with a multichannel port and utilizing the da Vinci robotic single-site platform. Two surgeons with extensive laparoendoscopic single-site experience participated.

Results: Forty patients had R-LESS performed. Procedures included total laparoscopic hysterectomy, laparoscopic supracervical hysterectomy, salpingo-oophorectomy, ovarian cystectomy, excision of endometriosis, and a combined case of total laparoscopic hysterectomy and cholecystectomy. Median age and body mass index were 42 years and 28.2 kg/m(2), respectively. Median operating time, defined as the interval between incision start to closure, was 134 minutes (range, 84-311 minutes). Median vaginal cuff closure was 21 minutes (range, 9-77 minutes). Overall, there appeared to be a linear relationship between vaginal cuff closure time, console time, and operating time with number of cases performed. Procedures were successfully performed via R-LESS in 92.5% of cases; 2 cases required 1 additional port and there was 1 conversion to traditional multiport robotic surgery. There was 1 major postoperative complication (2.5%) and 1 readmission (2.5%). After a median follow-up period of 230 days (range, 61-256), there have been no postoperative hernias diagnosed.

Conclusion: We present one of the first series of robotic laparoendoscopic single-site surgery for the treatment of various gynecological conditions. When performed by experienced minimally invasive surgeons, R-LESS is feasible and safe in select patients. Further studies are needed to better define the ideal gynecological procedures to perform using robotic single-site surgery and to assess the benefits and costs of R-LESS compared with multiport robotic and conventional laparoscopic approaches.
