Whether surgery is needed for stomach pain caused by right adnexal cyst depends on the specific situation. For acute abdomen caused by rupture or torsion of the cyst, emergency surgery is needed; for stomach pain caused by inflammation of the cyst, medication can be given to fight infection first, and then surgery can be performed if necessary. Ovaries and fallopian tubes are collectively known as adnexa, and adnexal cysts usually refer to the formation of fluid-filled cystic structures in the fallopian tubes and ovaries of women, and most patients do not have any obvious symptoms, but some patients may suffer from rupture, torsion, or infections, which can lead to sudden and severe abdominal pain. When a patient has an acute abdominal condition caused by a large adnexal cyst, rupture of the cyst, or torsion of the cyst, the patient should cooperate with the doctor to perform surgery as soon as possible, and can choose open or laparoscopic surgical treatment to improve the patient’s symptoms. For cyst inflammation and other causes of stomach pain, you can first drug anti-infection treatment, and then surgery if necessary. It is recommended that patients with right adnexal cysts should cooperate with their doctors to carry out standardized examination and treatment without delay.
