Objective To investigate the effect of transumbilical monopole laparoscopy in the treatment of ovarian cyst and its influence on ovarian function and pain degree. Methods? A total of 100 patients with ovarian cysts admitted to Tanzhou Hospital Zhongshan City，Guangdong Province from September 2017 to August 2020 were selected as the research objects and divided into control group and exprimental group according to the random number table method，with 50 patients in each group. The control group was treated by traditional laparoscopic ovarian cyst stripping，while the experimental group was treated by transumbilical monopole laparoscopic ovarian cyst stripping.The two groups of patients were compared with each operation index，the pain degree and ovarian function before and after operation. Results? The operation indexes and pain degree of the experimental group were better than those of the control group.After treatment，the sex hormone levels of the two groups were better than those before treatment（P＜0.05），but there was no significant difference in ovarian function between the two groups（P＞0.05）.Conclusion? Transumbilical monopole laparoscopic treatment of ovarian cyst can not only improve the clinical treatment effect，but also improve the patient's ovarian function and pain degree，worthy of clinical application.
