Adhesions typically begin to form within the first few days after surgery, but they may not produce symptoms for months or even years. As scar tissue begins to restrict motion of the small intestines, passing food through the digestive system becomes progressively more difficult. The bowel may become blocked.
At the time of implantation, the placenta starts making the pregnancy hormone hCG, which then enters the blood stream. hCG can be detected in the blood about 3 to 4 days after implantation. Urine hCG can be detected about 2 to 3 days after blood hCG can first be seen. Detection of hCG depends on timing of implantation so hCG can normally be detected in the blood between 9 and 16 days after ovulation (HPT: 12-19 days after ovulation).
Clinical Significance. hCG may reach detectable limits within 7-10 days of conception. hCG is produced by the placenta and reaches a peak between the 7th and 10th week of gestation. hCG is a glycoprotein hormone produced by the syncytiotrophoblast of the placenta and secreted during normal pregnancy and with pathologic conditions such as hydatidiform mole, choriocarcinoma and testicular neoplasm. Order hCG, Total, Qualitative, Urine, if hCG serum result is inconsistent with clinical presentation.
