Primary Abdominal Pregnancy: A Case Report.

Abstract

Abdominal pregnancy is a potentially life threatening form of ectopic gestation with an incidence of 1% of all the ectopic pregnancies. Rarely, it may reach at advanced gestation and a viable fetal outcome is indeed a rare event. Most of them are terminated earlier due to poor fetal prognosis and higher chances of maternal mortality secondary to haemorrhagic shock following spontanous placental separation. A high index of suspicion is important for making a diagnosis of abdominal pregnancy and its timely management after correct diagnosis. We report a case of primary abdominal pregnancy in a 30-year-old gravida 3, para 2 at 7+2 weeks of gestation. She presented with haemorrhagic shock due to spontanous separation of gestational sac from the site of implantaion. She had persisitent nausea, vomiting, diarrhoea and always had an urge to defecate which never goes off even after she defecates. She underwent termination of pregnancy by dilatation and curattage without having any antenatal ultrasound. After 72 hours of the procedure, her symptoms were aggravated and she went into haemorrhagic shock. During laparotomy haemoperitoneum of 3litres, 1kg of clots were evident and size of the uterus was about 10-12 week, bilateral tubes and ovary were healthy. A ensac fetus of 10+2 weeks along with the separated placenta was lying in the abdominal cavity. Site of implantation was identified over sigmoid colon which was not bleeding. Patient was transfused with blood and blood products. She was discharged satisfactorily on 5th postoperative day. Hence, an Ultrasound should be done to rule out abdominal pregnancy before medical termination of pregnancy, especially in those with persistent Gastrointestinal Tract (GIT) symptoms as clinically uterus may correspond to the period of gestation in abdominal pregnancy.
