    Abstract:
    BACKGROUND/AIM: The impact of venous resections and reconstruction techniques on morbidity after surgery for pancreatic cancer (PDAC) remains controversial. PATIENTS AND METHODS: A total of 143 patients receiving pancreatoduodenectomy (PD) for PDAC between 2013 and 2018 were identified from a prospective database. Morbidity and mortality after PD with tangential resection versus end-to-end reconstruction were assessed. RESULTS: Fifty-two of 143 (36.4%) patients underwent PD with portal venous resection (PVR), which was associated with longer operation times [398 (standard error (SE) 12.01) vs. 306 (SE 13.09) min, p<0.001]. PVR was associated with longer intensive-care-unit stay (6.3 vs. 3.8 days, p=0.054); morbidity (Clavien-Dindo classification (CDC) grade IIIa-V 45.8% vs. 35.8%, p=0.279) and 30-day mortality (4.1% vs. 4.2%, p>0.99) were not different. Tangential venous resection was associated with similar CDC grade IIIa-IV (42.9% vs. 50.0%, p=0.781) and 30-day mortality rates (3.5% vs. 4.1%, p=0.538) as segmental resection and end-to-end venous reconstruction. CONCLUSION: Both tangential and segmental PVR appear feasible and can be safely performed to achieve negative resection margins.
