EOD Mets
Notes
**Note 1:** The lesser sac of the peritoneum, or omental bursa, is the cavity in the abdomen formed by the lesser and greater omentum; the pancreas forms part of the posterior wall of the lesser sac.
**Note 2:** The specific location of the mesenteric nodes determines whether they are regional or distant. If the specific location is not described, code in EOD Regional Nodes.
**Note 3:** Porta hepatic nodes are distant for Body and Tail and should be coded in EOD Mets. If the specific location for hepatic nodes is not described, code in EOD Regional Nodes.
