[Evaluation of laparoscopic surgery in the early stage-malignant tumor of ovary with lower risk].

Abstract

To evaluate the laparoscopic operation for early ovarian malignant tumor with low risk. Ten patients with ovarian malignant tumor who underwent laparoscopic total hysterectomy, pelvic lymph nodes dissection, bilateral adnexectomy, ovarian aortic and vein high ligation, omentectomy, and additional appendectomy. Eleven patients with the same diagnosis who underwent operation by laparotomy were served as control group. The operation time, intraoperative blood loss, number of pelvic lymph nodes excised, and postoperative recovery were analyzed retrospectively. Frozen section method during operation proved the diagnosis of ovarian malignant tumor and cytological examination proved a negative result of the peritoneal irrigation liquid. The operation time was 298 min +/- 60 min for the laparoscopy group and 182 min +/- 43 min for the laparotomy group (P < 0.05). The intraoperative blood loss was 280 ml +/- 156 ml for the laparoscopy group and 346 ml +/- 170 ml for the laparotomy group (P < 0.05). The number of pelvic lymph node resected was 25 +/- 5 and 27 +/- 7 for the laparoscopy group and laparotomy group respectively (P > 0.05). The postoperative illness rate was 20.0% and 72.7% for the laparoscopy group and laparotomy group respectively (P < 0.01). Seven patients and 1 case in the laparoscopy group and laparotomy group left their beds 48 hours after operation (P < 0.05). The right obtuator nerve was injured and was sutured on 1 patient in the laparoscopy group. The whole procedure of total hysterectomy, bilateral adnexectomy, pelvic lymph node dissection, ovarian aortic and vein high ligation, omentectomy, and additional appendectomy may be performed under laparoscope in the treatment of early stage ovarian malignant tumor with lower risk. The laparoscopic operation has the advantage of less intraoperative bleeding, less morbidity and rapid recovery.
