The sacrum, also known as the sac of Douglas, is the lowest part of the peritoneal fold between the uterus (anterior) and the rectum (posterior). This is also the lowest area of the entire abdominal peritoneal cavity, and therefore also the first site where free fluid accumulates. So, if the ultrasound detects an abnormality, it will make some people worry whether the sac is along with the douglas and has any effect?
1. What is pocket translation with douglas?
On either side of the uterus are two sacral sacs, which are folds of the peritoneum onto the pelvic organs outside the peritoneal cavity. The anterior sacrum is the depression between the bladder and the uterus, while the posterior sac is located between the uterus and the rectum. The posterior pouch is also known as the Douglas pouch, named after Scottish physician James Douglas.
The position of the sac with douglas is lower than that of the anterior sacrum and is also the lowest position in the body. Therefore, sacral fluid along with douglas is the most common sign of any accumulation of fluid in the peritoneal cavity. All of the above features are anatomical in females. In men, the only sac is between the bladder and the rectum.
2. What is the cause of the same bag of fluid?
Liquids can appear and fill the same pocket for a variety of reasons. In women, gynecological causes are often more worrisome. For example, sacral fluid is sometimes caused by a ruptured ovarian cyst or a leaking cyst.
Here are some possible causes of ectopic pregnancy :
Ectopic pregnancy , where the pregnancy develops in the fallopian tubes instead of the uterus Endometriosis , when the type of tissue that normally lines the uterus develop somewhere else After aspiration, a procedure to remove the sac with too much fluid, Severe ascites, when excessive fluid builds up in the abdomen due to cirrhosis of the liver, kidney failure High doses of estrogen, increase Vascular permeability Ovarian torsion Ovarian torsion Abscess or hematoma in the pelvis, sac containing not only fluid but also pus and blood Pelvic inflammatory disease Retrograde menstruation, when menstruation flows back into the uterus and exits Fallopian tubes Abscesses, sacs filled with pus from the ovaries and fallopian tubes Uterine fibroids Uterine rupture In addition, sacs with fluid are also a common sign of infertility treatment. This could be a symptom of ovarian hyperstimulation syndrome, a condition in which high doses of reproductive hormones cause the ovaries to maximize in size.
3. What is the diagnosis of vesicles with douglas?
Transvaginal ultrasound will show whether there is fluid in the posterior sac of the uterus. This is a simple and easy test in which the doctor inserts a very long probe into the vagina to get more detailed ultrasound images. If fluid is found and the woman is in pain, the condition may require further testing to diagnose and plan treatment.
Another way to check the nature of sacral fluid and douglas is to aspirate the sacrum. To do this, the doctor inserts a needle through the vaginal wall to collect a sample of fluid from the sac while the patient is under anesthesia or sedation to relieve pain.
It is normal to have a small amount of fluid in the sac along with a serum-like nature. However, if the fluid sample shows signs of pus or blood, further drainage and investigation may be required.
If there is blood in the sac, the cause may be a ruptured cyst or a tear in the peritoneum. It could also be a sign of an ectopic pregnancy that has ruptured. If there is pus in the sacrum, this is evidence of an infection. Patients will need to be prescribed antibiotics for local infections, to prevent infection from spreading throughout the abdomen.
In short, the information above helps to explain what pocket and douglas are. Accordingly, fluid accumulation in this pocket if only a little is normal. However, if the sac contains pus or blood, or if it's causing pain, it could be a bigger health problem and needs to be treated before it spreads.
