Backgrounds/Aims: Abdominal drains are routinely placed following Frey procedure for chronic pancreatitis (CP) despite the low incidence of pancreatic fistula (PF). The utility of the first postoperative day (POD1) drain fluid amylase (DFA) value in predicting PF in CP patients undergoing Frey procedure has not been previously reported. Methods: A prospective study of patients with CP who underwent Frey procedure between August 2014 and April 2018. A standard technique of head coring with single layer continuous pancreatojejunostomy was done in all the patients. Amylase level of the drain placed close to the pancreatojejunostomy was recorded on POD1 and 3. Postoperative PF was defined and graded as per the updated International Study Group of Pancreatic Fistula (ISGPF) guidelines. Results: Fiftyfive patients with CP who fulfilled the inclusion criteria were included in the study. All had normal preoperative serum amylase level. Three patients developed a biochemical leak and four patients developed postoperative PF (Grade B - 3 and Grade C - 1). Receiver operating characteristics (ROC) curve identified a POD1 DFA cut-off value of 326 U/L that predicted a postoperative PF with sensitivity, specificity and negative predictive value of 100%, 70%, and 100% respectively. Conclusions: The POD1 DFA is a reliable predictor of postoperative PF in CP patients who have undergone Frey procedure. The PF can be confidently excluded in patients who have a POD1 DFA less than 326 U/L.
