Surgical SPCI was better evaluated than standard surgical PCI for surgeons in an easy and simple way.Conclusion Surgical SPCI is highly applicable for surgical staging in advanced ovarian cancer .CT SPCI correlates well with surgical SPCI which is an easier way than complicated standard PCI in advanced ovarian cancer.Disclosure Nothing to disclose.
