| Outline of Final Research Achievements |
Reposition of drains or reoperation after early removal of drains in patients with pancrearic head resection is harmful and stressful for both patients and surgeons. The aim of this study is to clarify objective predictive parameters of clinical relevant postoperative pancreatic fistula (CR-POPF) preoperatively. We investigated high risk factors for CR-POPF in surgical factors, morphologic and imaging factors from CT or MRI and proportion of fibrous tissue and adipose tissue at cut margin of the pancreas. Histological fibrous ratio of pancreas, morphologic ratio of [width of the pancreas] / [diameter of main pancreatic duct] by CT axial imaging and CT value ratio of [pancreatic parenchyma] / [erector spinae muscles] in late phase are statistically significant factors. Latter two factors are preoperative predictive factors. Careful management of drain for high risk group makes early removal of drains safer.
