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.
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.

DUODENAL OBSTRUCTION by the superior mesenteric artery (MESENTERIC ARTERY, SUPERIOR) which travels in the root of the MESENTERY and crosses over the DUODENUM. The syndrome is characterized by the dilated proximal duodenum and STOMACH, bloating, ABDOMINAL CRAMPS, and VOMITING. Often it is observed in patient with body casts after spinal surgery.
The artery supplying nearly all the left half of the transverse colon, the whole of the descending colon, the sigmoid colon, and the greater part of the rectum. It is smaller than the superior mesenteric artery (MESENTERIC ARTERY, SUPERIOR) and arises from the aorta above its bifurcation into the common iliac arteries.
Ischemic tissue injury produced by insufficient perfusion of intestinal tissue by the MESENTERIC CIRCULATION (i.e., CELIAC ARTERY; SUPERIOR MESENTERIC ARTERY; INFERERIOR MESENTERIC ARTERY; and MESENTERIC VEINS). It can progress from ISCHEMIA; EDEMA; and GANGRENE of the bowel wall to PERITONITIS and cardiovascular collapse.
