[Clinical analysis of leiomyomatosis peritonealis disseminate after laparoscopic uterine myomectomy in ten cases].

To investigate the clinicopathological features, treatment and prognosis of leiomyomatosis peritonealis disseminata (LPD). A total of 10 patients suffered from LPD after laparoscopic uterine myomectomy were collected in the First Affiliated Hospital of Zhengzhou University from September 2012 to September 2016, and all clinical database were retrospectively analyzed. (1)Clinical features: the age of 10 cases was 25-50 years old, and 8 cases of them were in child-bearing age, while 2 cases were in perimenopausal period.
