Post Sterilization Tubal Abortion with Haemoperitoneum and Negative Pregnancy Test - A Rare Case Report and Review of Literature

Introduction: Ectopic pregnancy is commonly seen as a differential diagnosis of first trimester vaginal bleeding. A negative urine pregnancy test traditionally excludes the diagnosis of pregnancy. Case: We report a rare case of ruptured ectopic pregnancy in a sterilized patient with a negative urine pregnancy test and with a serum beta-human chorionic gonadotropin (??-hCG) ofless than2 mIU/mL. The patient developed hemoperitoneum and required laparoscopy. The histopathological examination of the products later showed trophoblastic villi. Conclusion: This case highlights the limitations of the urine pregnancy test in diagnosing early pregnancy, the magnitude of the difficulties involved in the diagnosis of ectopic pregnancy and the importance of combining examination findings with ultrasound and laboratory results. Obstetrician must not exclude this potentially life-threatening condition in the presence of intraabdominal bleed or severe pelvic pain even with a negative urine pregnancy test.
