Patients rarely require drains after adrenal surgery; however, if the surgeon thinks it is necessary, an abdominal drain will be placed. Drains are more often required after open adrenalectomy than after laparoscopic adrenalectomy. Drains are relatively easy to take care of, and the output is recorded on a daily basis. Once the output decreases to a certain level, the drain will be removed. Removal of the drain is not particularly painful. It is more of a strange sensation. In general, the drain will be removed several days after surgery.

Even your propensity to develop certain kinds of diseases and your ability to respond to chronic illness is influenced significantly by the adrenal glands. The more chronic the illness, the more critical the adrenal response becomes. You cannot live without your adrenal hormones and, as you can see from this very brief overview, how well you live depends a great deal on how well your adrenal glands function. For a more detailed explanation of adrenal function, please refer to Dr. Wilson’s book: ”Adrenal Fatigue: the 21st Century Stress Syndrome”, and read Chapter 22: “Anatomy and Physiology of the Adrenal Glands”.

The alphafetoprotein is a glycoprotein synthesized in the yolk sac and in fetal liver in the first three months of pregnancy . Its blood level gradually decrease until it disappears completely at 2-3 weeks after birth.
GnRH is produced by placenta, especially in the first part of pregnancy. Its structure is similar to hypothalamic GnRH.
Identical to pituitary , ACTH is produced by cells of the syncytiotrophoblast and decidua at progressively higher concentrations, up to labor. Its production is modulated by placental CRF. The hormone probably acts in a paracrine way by influencing the placental steroidogenesis and intervening in labor.
IGF -I and IGF -II, insulin like growth factors , are growth factors produced by the trophoblast and later by fetus. They are important in the initial invasion of trophoblast and in the growth of the fetus.
The inhibin and activin modulate the growth and proliferation of various tissues; they are produced by the placenta and fetal membranes, reaching a peak at the end of pregnancy and modulate in different ways the endocrine activity of placenta.
Prolactin is an essential hormone for lactation. It is produced by the maternal hypophysis , the myometrium and endometrio. Prolactin rises between the tenth and the twelfth week, under the stimulus of high levels of estrogen. It then slowly decreases until the end of pregnancy. There is also a prolactin, produced by the decidua, equal to those hypophyseal, whose function is to reduce the permeability of amnios fluids and of electrolytes from fetus to mother.
