A good number of people struggle with the growth of ovarian cysts. Some ovarian cysts are physiological and can be absorbed naturally, but some cysts persist and should be treated early if they are larger so that they do not become twisted and cause severe abdominal pain, or if they continue to grow and eventually have to be operated on. Now we recommend a minimally invasive treatment method, which is as minimally invasive as an injection. I. Ultrasound-guided puncture for pelvic cystic lesions Under ultrasound guidance, a fine trocar needle is punctured to the center of the cyst, the cyst fluid is drawn out, and drugs are injected to cure the cyst wall and make it necrotic and absorbable. Fine needle puncture is minimally invasive, with quick recovery, reliable efficacy and low cost, and can be treated on an outpatient basis. Especially for patients after multiple surgical treatments and patients with pelvic and abdominal adhesions, ultrasound-guided puncture therapy has become the most effective and the only feasible treatment method. Our ultrasound-guided puncture therapy has been widely recognized by patients and colleagues. The main indications: 1. Recurrent chocolate cysts Chocolate cysts are cysts formed by endometriosis to the ovaries, which tend to cause pelvic adhesions and most patients are not easily pregnant. The main symptom is dysmenorrhea and recurrence is the main characteristic of the disease. In the past, treatment was based on surgical debridement, but in recent years, with the development of ultrasound-guided interventional techniques, the effect of ultrasound-guided puncture treatment of such benign cysts is comparable to that of traditional open or laparoscopic surgery. In the follow-up after treatment, the overall recurrence rate of ultrasound-guided interventional treatment was not significantly different from that of laparoscopic and open surgery, but the patients were less traumatic, less painful, safe and convenient to treat, and no significant discomfort after treatment. 2. pelvic encapsulated effusion Patients with a history of surgery are prone to the formation of pelvic encapsulated effusion, resulting in symptoms such as lower abdominal distension, discomfort, or lumbosacral discomfort. Ultrasound-guided puncture treatment is more effective, less painful and faster recovery. 3. Fluid or pus accumulation in the fallopian tube For patients without fertility requirements, this method has better treatment effect and quick recovery. 4. Simple cysts and ovarian crown cysts If the diameter of these cysts is less than 5 cm, they can be left untreated and reviewed regularly. If the diameter of the cyst is more than 5 cm, the chance of torsion increases. In case of torsion of ovarian cysts, abdominal pain is severe and emergency surgery is often required. To prevent the occurrence of torsion, puncture treatment is the best option.
