Objective To investigate the clinical effect of laparoscopic surgery on gynecologic malignancies,providing information for the clinical therapy.Methods 35 patients with gynecologic malignancies treated with laparoscopic surgery were selected as the observation group.While 35 cases of abdominal surgery patients were selected as control group at the same period.The incidence of postoperative complications,survival rate and other conditions of the two groups were observed and compared.Results The operation time of laparoscopic surgery group was longer than open surgery group,no significant difference between the two groups(P ＞ 0.05 ).Blood loss,hospital slay and recovery time of body temperature of the laparoscopic surgery group was significantly lower than open surgery group ( P ＜0,05).2 cases had urinary retention,1 urinary tract infection and 1 deep vein thrombosis occured in observation group; while 3 urinary retention cases,1 intestinal obstruction case,1 deep vein thrombosis case,1 abdominal wound infection case occured in control group,and the difference was significant ( P ＜ 0.05 ).2 patients lost in each group.3-year survival rate of laparoscopic surgery group was similar with open surgery,the difference between the two groups was not statistically significant( P ＜ 0.01 ).Conclusion Excision and pelvic lymph node dissection under laparoscopy is an effective method in treatment of gynecologic cancer,and with less trauma and faster recovery.
