Mesopancreas in pancreatic cancer: where do we stand - review of literature.
Pancreatic cancer is associated with poor prognosis and surgery remains the main modality of treatment. Negative resection margin is an important prognostic factor for survival. Retropancreatic margin or the medial margin is the most common site of positive resection margin. Mesopancreas was proposed in analogy with mesorectum, which is considered as a fusion fascia formed embryologically during the development of pancreas. This mesopancreas lies posterior to the pancreas and contains pancreaticoduodenal vessels, lymphatics, nerve plexus and loose areolar tissue. Various technical modifications were proposed for better dissection of mesopancreas like posterior approach and artery first approach. There is an increased rate of R0 resection by these technical modifications but whether this will turn to increase in survival rates is yet to be established.
