Objective To analysis and summary clinical characteristics of 15 patients who were diagnosed with abdominal pregnancy,which supply reference for clinical work. Methods 15 cases who were diagnosed with abdominal pregnancy and admitted to Guangdong Women and Children hospital between January 2002 and June 2018 were identified. Retrospective analysis was used to summarize the clinical characteristics of diagnosis and treatment in 15 patients. Test statistics used Student's t test to find if there was statistical difference between laparoscopic and abdominal surgery patients in perioperative period. Results One case was likely diagnosed with greater omentum pregnancy by type B ultrasound. Another one patient was diagnosed with abdominal pregnancy which has 8+ weeks pregnant single live fetus by type B ultrasound in other hospital prior to hospitalization.The B ultrasound tests of the other 13 patients showed there were no sac in uterus and enclosed mass beside uterus which were diagnosed with ectopic pregnancy, but not positive diagnosis with abdominal pregnancy.Surgery was performed for 14 patients.We found more different sites where gestational sacs plant in abdominal pregnancy patients in operation, 5 cases sacs planted in greater omentum, 9 cases sacs planted in pelvic cavity including 1 case sac planted in pelvic wall bottom-right bladder,1 case sac planted in rectum outside right-hand of Douglas pouch,2 cases sacs planted in right utero-sacral ligament,1 case sac planted in right-side of scar in lower uterus segment,1 case sac planted in adhesive tissue between the lift intestinal canal and uterus,1 case sac planted in right pelvic cavity,1 case sac planted in Douglas pouch,1 case sac planted in initiating terminal of the lift round ligament of uterus. The inteventional puncture with medical treatment was supply for only 1 patient,CT test showed the sac planted in abdominal: ahead of third lumbar vertebra between abdominal aorta and inferior vena cava. Conclusion There are more sites where gestational sacs can plant in abdominal pregnancy patients. Ultrasound is first choice for patient who was considered ectopic pregnancy and better to expansion the inspection range. MRI or CT may find sacs plant site who was considered abdominal pregnancy which may reduce missed diagnosis and misdiagnosis. Surgery is first performed who was diagnosed with abdominal pregnancy. Medical treatment for patients who vital signs are stable.
