title: Modification in the technique of pancreaticoduodenectomy: supracolic division of jejunum to facilitate uncinate process dissection.
abstract: Pancreaticoduodenectomy remains the recommended procedure for periampullary and pancreatic head tumors. The dissection of the uncinate process from the superior mesenteric vessels is a key step in this surgery. We describe a modification in the existing practice of infracolic division of the jejunum in order to facilitate this step. In this modification, the duodenojejunal (DJ) flexure and the proximal jejunum are delivered into the supracolic compartment and then the jejunum is divided. This exposes the uncinate process completely and facilitates the separation from the Superior Mesenteric Artery (SMA) and the Superior Mesenteric Vein (SMV). We have successfully employed this modified technique for 33 resections since February 2004. This modification of dividing the jejunum in the supracolic compartment is based on sound anatomic and embryologic grounds. It helps in aligning the uncinate process with the jejunal mesentery thereby making the dissection of uncinate process from the superior mesenteric vessels safe and complete.
