Omentum a much neglected structure. It is often removed in the context of gynecologic oncology procedure.
Grossing
- There is no widely accepted evidence-based standard; thus, the protocol differs from centre to centre.
- In the context of a gynecologic malignancy/suspected gynecologic malignancy:
- One centre I worked at puts through six (standard) blocks if there is no gross evidence of disease.
- One study suggests 3-5 blocks is enough if there is no macroscopic disease, and one block enough if there is macroscopic disease.[1]
- In the context of a gynecologic malignancy/suspected gynecologic malignancy:
