Radical omentectomy including the vascular perigastric arcade in stage FIGO III C serous ovarian tumors

Objective: The aim of this study was to document the presence of severe gastroplegia after radical omentectomy including the perigastric area and lesser omentum in patients with FIGO stage III C serous epithelial ovarian tumors (EOT). Methods: Patients undergoing radical omentectomy in the setting of surgery for FIGO stage IIIC EOT between Jannuary 2014 and Jannuary 2017 were included. Patients with macroscopic involvement of the perigastric area were excluded. The perigastric area was evaluated by an expert pathologist. Nasogastric tube was held for 48 hours. After that it was observed the recovery of gastric function. Results: Fifteen patients were included. All the patients underwent primary debulking surgery. Microscopic involvement of the perigastric omentum area was found in 37% of the cases. Five patients needed to put back the nasogastric tube for severe gastric sintoms. Summary: In this study, evidence is given that radical omentectomy including the perigastric area and lesser omentum is a necessary component of complete cytoreductive surgery in FIGO stage IIIC EOT, whatever great number of severe gastroplegia is reported.
