title: Single-port (OctoPort) assisted extracorporeal ovarian cystectomy for the treatment of large ovarian cysts: compare to conventional laparoscopy and laparotomy.
abstract: OBJECTIVE
  To evaluate single-port assisted extracorporeal cystectomy for treatment of large ovarian cysts and to compare its surgical outcomes, complications, and cystic content spillage rates with those of conventional laparoscopy and laparotomy.
  
  
  METHODS
  Retrospective study (Canadian Task Force classification II-2).
  
  
  METHODS
  University teaching hospital.
  
  
  METHODS
  Twenty-five patients who underwent single-port assisted extracorporeal cystectomy (group 1), 33 patients who underwent conventional laparoscopy (group 2), and 25 patients who underwent laparotomy (group 3).
  
  
  METHODS
  Surgical outcomes, complications, and spillage rates in group 1 were compared with those in groups 2 and 3.
  
  
  RESULTS
  Patients characteristics and tumor histologic findings were similar in the 3 groups. The mean (SD) largest diameter of ovarian cysts was 11.4 (4.2) cm in group 1, 9.7 (2.3) cm in group 2, and 12.0 (3.4) cm in group 3. Operative time in groups 1 and 2 was similar at 69.3 (26.3) minutes vs 73.1 (36.3) minutes (p = .66); however, operative time in group 1 was shorter than in group 3, at 69.3 (26.3) minutes vs 87.5 (26.6) minutes (p =.02). Blood loss in group 1 was significantly lower than in groups 2 and 3, at 16.0 (19.4) mL vs 36.1 (20.7) mL (p < .001) and 16.0 (19.4) mL vs 42.2 (39.7) mL (p = .005). The spillage rate in group 1 was profoundly lower than in group 2, at 8.0% vs 69.7% (p < .001).
  
  
  CONCLUSIONS
  Single-port assisted extracorporeal cystectomy offers an alternative to conventional laparoscopy and laparotomy for management of large ovarian cysts, with comparable surgical outcomes. Furthermore, cyst content spillage rate in single-port assisted extracorporeal cystectomy was remarkably lower than that in conventional laparoscopy.
