Ovarian tumors Although the ovaries are small in size , they are the organs most prone to tumors . The number of tumor types is also the highest among all organs in the body . Ovarian cancer is a common gynecological disease . It can occur at any age , but is more common in women of childbearing age . Because the ovaries are located in the pelvic cavity , they cannot be directly observed , and there are no symptoms in the early stages . There is a lack of good early diagnosis and identification methods . Once a malignant tumor is found , it is often in the late stage . Therefore, to date , the 5- year survival rate of ovarian cancer is still only 25%-30%, making it the most threatening disease among gynecological tumors . Tumor pedicle torsion About 10% of ovarian tumors are torsion . The condition for ovarian tumor pedicle torsion is that the tumor pedicle is long and the tumor is fist-shaped . Ultrasound examination shows that the head is as large as the fetal head , and there is no adhesion to the surrounding tissues . The tumor is easy to move in the abdominal cavity. Cystic teratomas, mucinous and serous cystadenomas are most likely to have pedicle torsion . The pedicles of these tumors are generally longer and the center of gravity is biased to one side . The tumor body is easily affected by intestinal peristalsis or changes in body position and rotates . Many patients complain that they have done activities such as getting up or bending over before the onset of pain, but sometimes the patient wakes up due to the onset of pain ( it may also be caused by turning over in sleep or intestinal peristalsis ). If the patient with ovarian tumor is pregnant , the tumor pedicle torsion often occurs in the first half of pregnancy or after delivery . Because the ovarian tumor rises into the abdominal cavity with the uterus in the second trimester , it has more room for movement than before in the pelvic cavity , resulting in a shrinkage of the uterus and a relaxation of the abdominal wall . The ovarian tumor has more room for movement , so it is also easy to have pedicle torsion . Rupture and puncture The former refers to the cyst rupture or squeeze , and its contents overflow into the abdominal cavity ; the latter refers to the cyst contents eroding the cyst wall and entering the abdominal cavity , such as the papillary protrusions of serous cystadenomas or cancers that penetrate the tumor wall . The rupture rate of ovarian tumors is about 3%, and malignant teratomas are most likely to rupture . Spontaneous rupture is more common . Due to rapid growth , the local blood supply of the cyst wall is insufficient , and the incremental cystic fluid breaks out from the weak part of the cyst wall and overflows into the abdominal cavity . Different tumor contents can cause different consequences in the abdominal cavity , and in the process of forming these conditions, it can cause complex inflammation, intestinal adhesions and even intestinal obstruction .
