This is an abnormal pregnancy in which the pregnant egg lays outside the uterine cavity and develops. It is also called “ectopic pregnancy”. Tubal pregnancy is the most common. The cause is often due to inflammation in or around the tubal lumen, causing poor patency of the lumen and preventing the normal operation of the pregnant egg, causing it to stay, settle and develop in the fallopian tube, resulting in miscarriage or rupture of the tubal pregnancy. There are often no obvious symptoms before miscarriage or rupture, but menopause, abdominal pain, and a small amount of vaginal bleeding may also occur. After rupture, the symptoms are acute severe abdominal pain, recurrent episodes, vaginal bleeding, and even shock. Examination often shows signs of intra-abdominal bleeding and a parametrial mass, and ultrasonography can help to diagnose. Treatment is mainly surgical, with open abdominal exploration and removal of the diseased fallopian tube while correcting shock. In order to preserve the reproductive function, the fallopian tube can also be incised to remove the pregnant egg. Early symptoms of ectopic pregnancy 1. vaginal bleeding, often a small amount. 2. Lower abdominal pain, cramping in the lower abdomen, a feeling of defecation, sometimes severe pain, accompanied by cold sweat. 3. Cessation of menstruation, with periods ranging from a few days to tens of days, often onset without detection. 4. Gynecological examination, positive pregnancy test, ultrasound scan or laparoscopy may assist in the diagnosis. 5.Other related symptoms, there can be nausea, vomiting, frequent urination.
