SUBTOTAL RESECTION OF THE HEAD OF THE PANCREAS PRESERVING DUODENUM AND VESSELS OF PANCREATIC ARCADE

me reported a procedure of duodenum-preserving subtotal pancreatectomy of the pancreas according to the precise anatomy of the pancreatoduod enal region, especially of the pancreaticoduodenal arteries which. pro vide blood to the duodenum. After a complete Kocher's maneuver is perf ormed, the pancreas is cut-above the portal vein and removed from the third portion of the duodenum, followed by the removal of the posterio r surface of the pancreas head from a connective tissue membrane. The main pancreatic duct is identified at its junction with the terminal p ortion of the bile duct from the posterior-surface of the head of the pancreas and is cut at the junction. The pancreas is cut in the line o f-the ASPD. The reason we leave the part of the pancreas between the d uodenum, ASPD and the common bile duct is that the artery toward the p apilla of Vater runs along the right side of the common bile duct and would be difficult to be preserved with the removal of this part of th e pancreas. The most important techniques of this procedure is to Keep the connective tissue membrane of the posterior surface of the pancre as intact so as to preserve pancreaticoduodenal arteries and veins. Be nign lesions as well as low-grade malignancy of-the head of the pancre as may be possible indications for this procedure.
