Ovarian teratoma can be minimally invasive surgery, if the patient’s teratoma is too large, then minimally invasive surgery is not recommended. Ovarian teratoma is the most common tumor derived from primitive germ cells, the etiology of which has not been clearly defined and is mostly related to congenital defects, chromosomal abnormalities and other factors. For the treatment of ovarian teratoma, different treatment modalities need to be selected according to the type of pathology. Ovarian teratoma can be treated by minimally invasive surgery, if the patient’s teratoma is relatively small, this situation can be treated by laparoscopic minimally invasive surgery. If the patient’s ovarian teratoma is too large, there is no way to perform minimally invasive surgery as the oversized teratoma will take up most of the pelvic and abdominal volume. When patients find ovarian teratoma, it is recommended to consult a doctor in time, complete the relevant examination, and choose the appropriate treatment plan according to the patient’s own condition and the size of the teratoma and other comprehensive analysis and judgment by a professional doctor.
