Objective To investigate the effectiveness and surgical techniques of the improved laparoscopic treatment of ovarian dermoid cyst to prevent the occurrence of intraoperative rupture of teratomat, so to preserve the ovarian function at the maximum. Methods The modified laparoscopic extra-cavity and cavity outside the teratoma removed surgical suture treatment from February 2005 to February 2009,39 cases with large dermoid cyst were trea-ted by improved surgery and 45 cases treated by normal removal of laparoscope. The rupture, surgery time, bleeding volume,frequency of use of electrocoagulation and the effect of body temperature on intestinal canal and hospitaliza-tion day after operation as well. Results 39 cases of dermoid cyst were successfully managed by improved laparo-scopie surgery, during which no cyst contents broke into the abdominal cavity, no one was placed on electrocoagula-tion to stop bleeding, bleeding volume was (35.13±5.49) ml, operative time was (36.07±12.53) min, significantly leas than that of normal laparoscopic surgery group [the cyst rupture rate was 46.7% (21/45), the frequency of elec-trocoagulation was (5.0±3.0) times, the duration of electrocoagulatian was (5.5±2.5) s, bleeding loss was (40.73±6.04) ml and the time for operation was (67.47±20.73) min], with significant difference between the two groups (P<0.05 or 0.01);howevere, there was no remarkable difference in the effect of the two types of surgery on postoperative body temperature,anal exhaust time,postoperative hospitalization day. Conclusions In addition to minimally invasive laparoscopic surgery in the treatment of gastro-intestinal effects of small, quick recovery, the im-proved laparoscopic surgery for dermoid cyst shortens the operation time. The improved abdominal cavity and suture outside the strip surgical method can effectively prevent the complication caused by intraoperative tumor capsule rup-ture,reduce electrocoagulation injury,and preserve the ovarian function at the maximum.
