Omentum pregnancy resulting in severe hemoperitoneum: Lessons learned from a review of the literature along with a case report.

Abdominal pregnancies are a rare form of ectopic pregnancy with omentum pregnancies being even rarer. Ectopic pregnancy should be diagnosed and terminated early to prevent the risk of harm to the mother. This case report describes a rare case of omentum pregnancy with severe hemoperitoneum. The patient had not visited a doctor until she failed to menstruate for 3 months, by which point she had developed severe hypogastralgia. The patient was diagnosed with a ruptured ectopic pregnancy after ultrasonography. The omentum pregnancy was complicated by severe hemoperitoneum, which was confirmed by emergency laparotomy. The patient was treated successfully with fetal extraction and partial omentectomy. Ultrasound examination in early pregnancy is essential to detect and treat ectopic pregnancies as early as possible, as surgery is usually required for abdominal pregnancies. Prompt treatment of ectopic pregnancies is critical, as an omentum pregnancy is dangerous and may result in severe intraperitoneal bleeding.
