The cost of chocolate cyst puncture is about 3000-4000 RMB, which may vary from hospital to hospital and from region to region. In general, some tests are routinely performed before chocolate cyst surgery, including ultrasound examination to understand the size and location of the cyst, white belt examination to understand whether there is inflammation of the vagina, routine blood tests, infectious disease tests, electrocardiogram tests and four coagulation tests. If there is no abnormality in the examination, cyst puncture surgery is performed under ultrasound monitoring, and the puncture route is designed in advance to avoid the large blood vessels and intestinal canal in the abdominal cavity. Normally the chocolate cyst sac is filled with blood and the stagnant blood extraction tends to cause stickiness, so repeated flushing and aspiration is required, and anhydrous alcohol is injected to harden the cyst after it is aspirated. Whether it is laparoscopic cyst debridement surgery or open cyst debridement surgery, there is a chance of recurrence, so it is possible to perform a chocolate cyst puncture surgery, which is more minimally invasive. After the operation, we should pay attention to rest for one month, avoid heavy physical labor, pay attention to hygiene, strengthen nutrition, and go to the hospital for ultrasound examination after one month.
