An ectoptic pregnancy is one where the embryo implants anywhere other than in the uterus. Extrauterine abdominal pregnancy is one variant and is extremely rare and the only one where the fetus can survive to term, but occurs only in 0.9% of cases. Abdominal pregnancies are when implantation occurs within the peritoneal cavity are thought to result from tubal abortion or rupture with subsequent reimplantation of the conceptus onto bowel, omentum or mesentery.It typically develops around the ligaments of the ovary, on the uterus or in the pouch of Douglas, although it can implant anywhere within the abdominal cavity.
