Abstract: Ovarian cancer is gynecological malignancy with the highest death rate from the disease.Due to the insidious nature of ovarian cancer， the majority of patients at time of diagnosis have progressed to stage Ⅲ or stage Ⅳ disease. Surgery is the main treatment of ovarian cancer， optimal cytoreduction is the independent factors affecting prognosis. Patients with advanced ovarian cancer often have disease invading the upper abdomen， most commonly， the diaphragm，about18%-42%. And the metastasis is also difficult to managed，leads to suboptimal cytoreduction with reducing survival rate。A number of surgical techniques are available to effect cytoreduction of diaphragmatic involvement by ovarian cancer。Diaphragm metastasis is not abstacle of optimal cytoreduction， and diaphragm resection is necessary procedure of cytoreduction. This Article is to describe the application of the technology in ovarian cancer.
