Objective Retrospective analysis of the cases in ectopic pregnancy, To summarize the incidence of ectopic pregnancy,and ultrasonic performance charancteristics; analysis of ultrasonic imaging charancteristics in ectopic pregnancy of the tubal different segment and the key points of differential diagnosis, so that to better recognize ectopic pregnancy、to improve diagnosis accuracy of ectopic pregnancy. Methods 115 case of ultrasound diagnosis of ectopic pregnancy, to analyze and study of laparosopic surgery. Comprehensively observe the uterus、ovary、fallopian tube、lesion, and observe the relationship with the location of the uterus and the ovary. Focus on scanning the attachment area between ovarian and uterus. Results the incidence of tubal ectopic pregnancy in interstitial tubal was 9.5%(11/115), the incidence of tubal ectopic pregnancy in tubal narrow was 14.7%(17/115), the incidence in tubal ampulla was 71.3%(82/115), the incidence in tubal umbrella department was 4.3%(5/115). The diagnosis accuracy of each section of tubal ectopic pregnancy was different, interstitial tubal:64%、tubal narrow:29%、tubal ampulla:85%、tubal umbrella department:20%.
