Recurrence Tumor Clinical Trial
Official title:
A Prospective Randomized Study of the Usefulness of the Artery First Approach in Pancreatic Cancer With Pancreaticoduodenectomy
This study is aimed to evaluate difference of the 2 year recurrence free survival after pancreaticoduodenectomy for pancreatic cancer between artery-first approach and conventional procedure groups.
The patients will be divided into 2 groups conventional group: The patients who included this group will undergo conventional pancreaticoduodenectomy (PD) or pylorus preserving pancreaticoduodenectomy (PPPD). We will identify and isolate superior mesenteric vein (SMV) before pancreatic resection. The surgeon will dissect tissue around superior mesenteric artery (SMA) and uncinate process of pancreas along the SMA. Experimental group: The patients who included this group will undergo PD or PPPD including total pancreatic mesopancreas excision and superior mesenteric artery approach. Before pancreatic transection, the surgeon will isolate superior mesenteric vein (SMV) and superior mesenteric artery (SMA). And the surgeon will dissect nerve plexus and lymph node around SMA. inferior pancreaticoduodenal artery (IPDA) and first jejunal artery will be identified and the surgeon will ligate according to surgical margin. Anastomosis will be performed as usual manners. Postoperative manage is same in two groups. The investigators will compared 2 years recurrence free survival rate between conventional and experimental groups. ;
