Post-Operative Acute Pancreatitis After Pancreaticoduodenectomy

Surgical resection and reconstruction will be carried out according to the Institutional standards. After the surgical procedure, serum pancreatic amylase and lipase activity will be systematically measured two hours after surgery on postoperative day (POD) 0 and every day at 7 a.m. until POD 5 according to our institutional policy. At our institution, the upper limit of normal for serum pancreatic amylase is 52 U/L and for serum lipase is 60 U/L. Postoperative protocols included the routine measurement of inflammatory markers (white blood cell \[WBC\] count and C-Reactive Protein \[CRP\]). A urine trypsinogen strip test will be done on POD 1. A trypsinogen-2 concentration of more than 50 µg/l is considered a positive test. As routine clinical practice, a post-operative imaging will be scheduled to check for potential surgical morbidity. Abdominal magnetic resonance imaging (MRI) will be assessed on POD 3.
