AbstractAcute hemoperitoneum (AHP) in early gestation is commonly treated via laparotomy. A ruptured corpus luteum (CL) cyst is a rare cause of AHP in pregnancy. This case report describes a 33-year-old, hemodynamically stable G2/P1 who presented at 5+5 gestational weeks with an acute abdomen due to ruptured CL cyst (7 cm). Emergent laparoscopy was performed. After evacuation of 1 L of hemoperitoneum, an atraumatic hemostasis was obtained without diathermy by use of hemostatic matrix (Floseal®). The ovary was reformed with an absorbable suture under preservation of CL. The postoperative recovery was uncomplicated. The hemoglobin drop was 2.8 g/dl. Further pregnancy course was uneventful. A healthy baby (2860 g) was delivered vaginally at 38+3 weeks of gestation. Conclusion Laparoscopic approach to AHP in early pregnancy is suitable. CL preservation is feasible by use of atraumatic hemostatics.
