Objective To investigate the clinical effect and safety of laparoscopy on ovarian benign tumor. Methods The data of 68 patients, underwent laparoscopic operations on ovarian benign tumor from Jan 2009 to Jan 2010, were analyzed retrospectively. Sixty eight patients underwent laparotomy were randomly enrolled as control. The operative time, the blood loss, the average admission day and the average postoperative exhaust time were compared between two groups. Results We found no significant differences in the comparation of operative time ( [ 63.60 ± 7.71 ] min vs. [ 62. 40 ± 8. 90 ] min, t = 0. 663, P ＞ 0. 05 ), while the blood loss, the average postoperative exhaust time, the average admission day of the treatment group were significantly lower in the objectives than control ( [ 68.00 ± 14. 90 ] ml vs. [ 119.00 ± 19. 60 ] ml, [ 17.30 ±2.40]h vs. [34.60 ±2.80] h, [3.90 ± 1.40] days vs. [7.70 ± 1.50] days,t =2.664, 2. 523,2.724,Ps ＜0. 05). Conclusion Laparoscopy is the first choice of method in treating ovarian benign tumor given its minimal invasion and rapid recovery.
