The definitions for R0 and R1 margin status after resection for pancreatic cancer are controversial.Various studies showed the rate of noncurative resections of 15- 35 % but with modified pathological examination (R1/R2) revealed the rate of R1 resection was higher ranging from 76-85 % . Verbeke CS etal. * Whether this discrepancy was caused by incomplete lymphnode dissection, perineural dissection and improper pathological examination was not yet known. * Perineural invasion was detected in 77 % of specimens of resected pancreatic cancers. So the researchers emphasized the need of new surgical classification involving mesopancreas. It can be considered as an anatomical space bounded anteriorly by the the posterior surface of the pancreatic neck, posteriorly by the pancreaticoduodenal coalescence fascia, medially by the mesenteric vessels with -nerves, lymphatics and vessels as its contents.
