Are Metastatic Central Lymph Nodes (D3 volume) in right-sided Colon Cancer a Sign of Systemic Disease? A sub-group Analysis of an Ongoing Multicenter Trial.

Objective: Assess outcomes of patients with right-sided colon cancer with metastases in the D3 volume after personalized surgery.

Background: Patients with central lymph node metastasis (D3-PNG) are considered to have a systemic disease with a poor prognosis. A 3-dimensional definition of the dissection volume allows the removal of all central nodes.

Bowel Motility After Injury to the Superior Mesenteric Plexus During D3 Extended Mesenterectomy.

Background: Improvement of lymphadenectomy in right colectomy requires removal of all tissue surrounding the superior mesenteric vessels beneath the pancreatic notch. Short- and long-term bowel motility disorders after D3 extended mesenterectomy with consecutive superior mesenteric plexus transection are studied.

Methods: Patients without pre-existing motility disorders undergoing D3 extended mesenterectomy were examined 3 times using the wireless motility capsule: before, at 3 wk, and 6 mo after surgery.
