Case report: We report a case involving primary uterine serosal pregnancy treated via laparoscopic surgery. A 35-year-old woman with suspected ectopic pregnancy was referred to our hospital. We were unable to detect a gestational sac in the uterus or implantation site by imaging. Her urine human chorionic gonadotropin (hCG) level was 18,835 mIU/mL. Exploratory laparoscopy was performed to examine her abdominal cavity. Both of her fallopian tubes were normal. We found a gestational sac on the uterine serosal surface. Vasopressin was injected into the myometrium to reduce bleeding, and the part was dissected with minimal bleeding using monopolar and bipolar forceps. A pathological examination revealed the presence of chorionic villi and trophoblastic cells. Her postoperative course was good, and the patient was discharged on the fourth postoperative day. Overall, laparoscopic surgery was useful for the early diagnosis and treatment of peritoneal pregnancy.
