The DISSECT Study: Effect of Peri-aDventItial SMA diSsECtion on Margin sTatus During Pancreaticoduodenectomy for Resectable Pancreatic Cancer

lymphoneural tissue around SMA left intact

"For the patients randomised for peri-adventitial dissection the right side of the SMA should be completely clear from lymphoneural tissue for at least 180 degrees on right side and from angle of the artery to the level of inferior border of the uncinate process. In the presence of an accessory or replaced right hepatic artery the peri-adventitial dissection should also be carried out around this vessel as well."
