A Multicenter Randomized Controlled Study of External Pancreatic Duct Stents in Pancreaticoduodenectomy
The prognostic value of external vs internal pancreatic duct stents after pancreaticoduodenectomy remains controversial. This study aimed to evaluate the benefits of external and internal stents using the Updated Alternative Fistula Risk Score in both high-risk and low-risk patients with regard to the incidence of clinically relevant postoperative pancreatic fistula.
• Pancreatoduodenectomy with pancreaticojejunal mucosa anastomosis was performed;
⁃ The patient has no combined organic diseases in the heart, lungs, or kidneys;
‣ No history of chemotherapy, radiotherapy, upper abdominal surgery, or combined with other tumors; ④ The risk score of the pancreatic fistula of the patient according to the definition of the updated Alternative Fistula Risk Score (ua-FRS). Patients with a ua-FRS score higher than 5% were included in this study.
