Cyst torsion refers to a sudden change in the patient’s position when the cyst appears to rotate 180°360° causing severe pain to the patient. It is mostly seen in ovarian cyst torsion. Different treatment methods can be taken according to the severity of torsion: a. For lighter ovarian cysts with mild torsion, the patient will have abdominal pain and abdominal distension, etc. At this time, the patient can lie down and rest, improve gynecological ultrasound examination and observe the torsion of the cyst. If the cyst can be reset by itself and the pain symptoms can be relieved significantly, surgery may not be needed for the time being; if the cyst is repeatedly twisted during the process of close observation, surgery can be considered; secondly, once the cyst is twisted in larger size, it often cannot be reset by itself. If the patient’s abdominal pain is persistently aggravated, surgical exploration can be considered to remove the cyst; if the ovary is accompanied by necrosis, it needs to be removed together and postoperative anti-infection treatment can be strengthened to achieve better treatment results.
