A Multicenter Big⁃Sample Retrospective Study of Pancreaticoduodenectomy

For patients with malignant or benign disease of the pancreatic head and periampullary region, pancreaticoduodenectomy is the only potential approach to radical cure. However, pancreaticoduodenectomy is consider as one of the most complex operations associated with a high rate of postoperative complications such as pancreatic fistula, delayed gastric emptying, hemorrhage, abscess, and sepsis. These complications increase the costs associated with pancreaticoduodenectomy. Numerous interventions and techniques have been introduced to decrease the morbidity. But there is little evidence for the superiority of one anastomotic technique over the others. Therefore, investigators intend to conduct a multicentre, big-sample, retrospective study to analysis the surgery results of pancreaticoduodenectomy and compare the different suture technique.
