Abstract: 【ABSTRACT】Objective: To analyze the clinical effect of laparoscopic and open surgery in the treatment of early ovarian cancer. Methods:78 cases of early ovarian cancer patients were studied,39 cases were treated by laparoscopy,39 cases were treated by open surgery, and the cases were compared with two groups of patients. Results:The patients in the laparoscopic group the operative time and blood loss less than control group, lymph node resection counts more than the control group, intraoperative bleeding volume difference significant (P＜0.05), the operation time and lymph node resection differences not significant. Laparoscopic postoperative anus ventilation and hospitalization time, postoperative fever and complications occurrence rate, postoperative chemotherapy proportion is lower than the open surgery group, postoperative anal exhaust time, hospitalization time, postoperative fever and complications occurrence rate difference was statistically significant (P＜0.05) and postoperative chemotherapy the number difference no statistical significance (P＞0.05). Conclusion:Laparoscopic treatment of early ovarian surgery is better than open surgery, and safe and reliable, can be used as the first choice for the treatment of ovarian cancer.
