Core Tip

Core Tip: The overall incidence of perineal endometriosis (PEM) is low, accounting for only 0.31% in women with endometriosis treated by surgery. At present, there are few clinical studies on the incidence and clinical characteristics of PEM. This study summarizes the clinical data of 14 PEM cases who visited The International Peace Maternal and Child Health Hospital Affiliated to Shanghai Jiaotong University during the past 11 years. Furthermore, we analyze the incubation period-related factors and pain-related factors of PEM to provide suggestions for the prevention and treatment of PEM.
