Objective:
To investigate clinical outcome of laparoendoscopic single-site compared with traditional three-port in treatment of ovarian cystectomy.
Method:
From February 2012 to June 2013, 54 patients with ovarian cyst were randomized to the single-site group (n = 24) or the three-port group (n = 30) in Peking Union Medical College Hospital. The outcome of laparoscopic single-site and three-port ovarian cystectomy were evaluated. Operation time, blood loss, surgical complications, postoperative pain score, postoperative analgesic requirements, length of hospital stay, cosmetic satisfaction score, postoperative recovery and total cost were compared between both groups.
Results:
No difference was found in blood loss, length of hospital stay, complications and total cost between the two groups (P > 0.05). Operation time was (31 ± 10) minute in three-port group and (40 ± 19) minute in single-site group. Visual analogue pain score was 5.6 ± 1.7 in three-port group and 2.7 ± 1.4 in single-site group, cosmetic satisfaction score was 92.5 ± 2.5 in three-port group and 97.4 ± 1.5 in single-site group. Those clinical parameter reached statistical difference (all P < 0.05).
Conclusion:
Laparoendoscopic single site surgery approach is feasible and safe to treat benign ovarian cyst disease. And it offers decreased pain and offer improved cosmesis.
