Abstract: Epithelial ovarian cancer (EOC) is a common gynecologic carcinoma in women. It holds high recurrence rate and mortality due to dormant symptom. The standard treatment of EOC includes primary debulking surgery followed by chemotherapy. EOC have a clear predilection for metastasis to the omentum and hence omentextomy is an important part in EOC surgery. However, the scope of surgery remains disputed. All involved omentum should be removed if there is gross disease in the omentum. To those patients without gross disease in the omentum, the scope of surgery depends on the surgeon. The commonest one is an infracolic omentectomy while expanded resection may bring more benefits and complications to patients. A review of omentectomy in the staging and treatment of EOC was conducted to provide more accurate treatment for different EOC patients.
