M. D. Anderson criteria for defining resectability status of pancreatic cancer [3, 4].

Resectable
(i) No distant metastases
(ii) No extension to the SMA; normal fat plant between the tumour and SMA
(iii) No extension to the coeliac axis or HA
(iv) Patent SMV/PV
Borderline resectable
(i) Tumour abutment ≤180° (≤50%) of the circumference of the SMA
(ii) Short-segment encasement/abutment of the CHA (typically at the GDA origin)
(iii) Short-segment occlusion of the SMV/PV with suitable vessel above and below
Unresectable
(i) Encased SMA (>180°)
(ii) Encased HA with no technical option for reconstruction
(iii) Occluded SMV/PV wih no technical option for reconstruction

CHA = common hepatic artery

GDA = Gastroduodenal artery

HA = Hepatic artery

PV = Portal vein

SMV = Superior mesenteric vein

SMA = Superior mesenteric artery.
