Single-incision and single-port laparoscopic surgery versus conventional multi-port laparoscopic surgery for treatment of benign ovarian tumor

Objective To study the feasibility of transumbilical single-incision laparoscopic surgery(SILS)and single-port laparoscopic surgery(SPLS)for the treatment of benign ovarian tumors.Methods Eighty patients with benign ovarian tumors who underwent laparoscopic surgery at Peking University First Hospital between September 2013 and June 2014 recruited in this study,among them 25 were transumbilical single-incision laparoscopic surgeries(SILS),25 were single-port laparoscopic surgeries(SPLS)and 30 with conventional multi-port laparoscopic surgeries(MPLS).Data of these patients were analyzed retrospectively.Results In the three groups,all procedures were performed successfully.There were no differences between SILS,SPLS and MPLS groups in the median operation time(51min,56 min and 45 min,P0.05),the median blood loss(10ml,10 ml and 15 ml,P0.05),and the absolute decrease of hemoglobin from preoperative to postoperative day 3measurements(7g/L,8g/L and 6g/L,P0.05).Conclusion SILS and SPLS are feasible and safe approach for the treatment of benign ovarian tumors.
