The aim of the study was to determine the risk factors for surgery in patients with hemoperitoneum caused by corpus luteum cyst rupture. A retrospective review of medical records of 155 patients diagnosed with hemoperitoneum caused by corpus luteum cyst rupture was conducted between January 2010 and March 2015. The patients were divided into two groups: surgical and conservative management. The differences in characteristics between the two groups were compared. The indicators that determine the need of a surgery at the initial visit were also compared between the two groups. Initial hemoglobin level was lower (11.3 ± 1.4 g/dL vs. 12.2 ± 1.2 g/dL; p = 0.007) in the surgery group. There were significant differences in posterior cul-de-sac (PCDS) fluid collection depth (6.2 ± 2.5 cm vs. 4.5 ± 1.6 cm, p = 0.000), total fluid collection depth (8.4 ± 1.8 cm vs. 6.5 ± 2.1 cm, p = 0.000), single deepest pocket depth (6.7 ± 2.2 cm vs. 5.1 ± 1.5 cm, p = 0.006), liver-dome fluid (78.9% vs. 35.6%; p = 0.002), and estimated intrapelvic bleeding amount (325 ± 250 cc vs. 206 ± 146.5 cc, p = 0.002). The extravasation over grade 2 was more often in surgery group (68.4% vs. 30.1%; p = 0.001). PCDS fluid collection depth, the presence of liver-dome fluid, and the severity of contrast extravasation through ultrasonography and computed tomography are good indicators for determining the management of hemoperitoneum resulting from corpus luteum cyst rupture in healthy women.
