One of the common causes of miscarriage is when the embryo attaches outside outside the uterus, in the ovary, abdomen or cervix and this is known as an extrauterin or ectopic pregnancy. In 95% of ectopic pregnancies the fertilised egg implants itself in the fallopian tube and begins to develop. A developing egg cannot grow outside the uterus as it needs nourishment and room to grow and this causes a miscarriage.
It can be difficult to diagnose an ectopic pregnancy at first as the hormone Human Chorionic Gonadotropin (HCG), is produced as in a normal uterine pregnancy and the symptoms are the same. However, there can be vaginal bleeding and abdominal cramps indicating something is wrong. If an ectopic or tubal pregnancy is left undiagnosed symptoms can get worse and result in other problems such as heavier bleeding, sharp tummy pains and dizziness.
Surgical treatment may take place by laparascope and a cut in the bikini line. Whether the laparascope viewing operation is possible depends on the severity of complaints and whether there is any bleeding or other abnormalities in the abdomen. During the operation, a tubectomy may be the best course of action. This is usually undertaken if there is bleeding in the fallopian tubes, if the EUP is advanced, or if this is the second time in the same fallopian tube.
