Laparoscopic surgery with spleen preservation to treat primary splenic pregnancy: Case report and literature review.

Splenic pregnancy is a rare form of ectopic pregnancy, with only 21 cases reported in PubMed since 1970. Here we report the case of a healthy 28-year-old woman with splenic pregnancy who complained of menolipsis lasting 56 days and left upper quadrant pain lasting 30 days. The level of β-human chorionic gonadotropin in serum was 8399 mIU/mL, and transvaginal ultrasonography showed the uterine cavity to be empty without signs of adnexal mass. Subsequent abdominal ultrasonography detected a hyperechoic mass below the spleen containing an anechoic mass measuring 2.6 × 1.2 × 1.6 cm. Laparoscopy detected a gestational mass measuring 6.0 × 4.0 × 3.0 cm on the lower border of the spleen. Pregnancy tissues and a clot were removed under laparoscopic guidance, and the spleen was preserved. Our case suggests that removal of chorionic villi tissue, although not a standard procedure, may be effective for treating splenic pregnancy.
