Abstract:
Objectives To study ho to make an accurate diagnosis of ectopic pregnancy in the early stage through different ultrasonic checking ways, so as to decrease the misdiagnosis and missed diagnosis rates. Methods 195 cases of ectopic pregnancy patients, which were diagnosed by abdominal ultra-sound (TAS) or by vagina ultra-sound (TVS), were collected, then compared with the operational pathological results and anzlyzed the reasons of the misdiagnosis and missed diagnosis, so as to find out the best ultrasonic way. Results 195 cases of ectopic pregnancy patients were diagnosed by ultrasound, the positive coincidence rate was 95.4% (186/195), misdiagnosis rate was 4.1% (8/195) and missed diagnosis rate was 0.5% (only 1 case). Among 186 cases of ectopic pregnancy, which totally conformed to the operational pathological results, 82 cases were pelvic adhesion, 51 cases (62.2%) were diagnosed ectopic pregnancy by TAS. 104 cases were not pelvic adhesion, in which 48(46.2%) cases were diagnosed ectopic pregnancy by TAS, then the significant differences were being shown. Conclusions When in pelvic adhesion, the ultrasonic checking way is mutually related to the positions of the oviduct and ovary in the pelvic cavity. When the oviduct and ovary are pressed close to the anterior abdominal wall, TAS is the best way while they are pressed close to posterior pelvic wall, TVS is the best way. The ultrasonic checking way for ectopic pregnancy is varied upon different patients.It is the main reason of misdiagnosis and missed diagnosis, that the clinical material and dynamic observation were not taken into consideration
