After the SMV was identified at the inferior border of the pancreas, the gastrocolic trunk was divided, then duodenum and pancreatic head were mobilized, inferior vena cava, left renal vein and SMA were dissected and lymphadenectomy was performed respectively. The proximal jejunum was transected by using a stapler and IPDA was clipped and divided. Afterward, the pancreatic head was isolated from the PV/SMV and the posterior-superior pancreaticoduodenal veins were divided on the right side of the SMA. Additionally, the common hepatic artery originates from superior mesenteric artery was explored. After transected distal stomach by using a stapler, the right gastric artery and the gastric duodenal artery were identified and divided, then the portal vein was exposed. Subsequently, the pancreatic neck was transected, the common bile duct was exposed and taped. After the gallbladder was removed, the bile duct was dissected. After resection, a conventional loop reconstruction was performed including an end-to-side pancreaticojejunostomy with modified duct-to-mucosa technique and single-layer continuous suture with 4-0 Prolene. Subsequently, the end-to-side running suture hepaticojejunostomy with 4-0 Proleneand side-to-side gastrojejunostomy with 3-0 Prolene. Pathology confirmed R0 resection for a moderately differentiated adenocarcinoma graded pT₂N₁M₀.
