P-P54 Interpreting trends in post-operative drain fluid amylase according to type of anastomosis used to form a pancreaticojejunostomy

a composite outcome to determine the success of the quality of the surgical process, and compare outcomes between institutions and patient groups, described by the Dutch Pancreatic Cancer Audit Group for Pancreatoduodenectomy (PD). They reported national TOs for PD of 58.3%, we compared this to TOs in a UK high volume specialist pancreas-only centre, Royal Stoke. Methods: Patients who underwent PD from January 2017 to December 2020 were identified from our database. TO was defined as absence the following: post-operative pancreatic fistula (POPF) (grade B/C), postpancreatectomy haemorrhage (PPH), bile leak, severe complications (Clavien Dindo grade III or more), 30-day readmission and 30-day mortality. Results: 153 patients underwent PD during the 4-year study period. The median age was 71years (range 37-85 years), and there was a slight male preponderance (54.9%, 84/153). 47% had pancreatic ductal adenocarcinoma (72/153), 17% ampullary carcinoma (26/153), 9% cholangiocarcinoma (14/153), 9% duodenal carcinoma (14/153), and benign pathology included cases with IPMN and duodenal polyps with high grade dysplasia. There was a statistically significant difference in textbook outcome in our cohort compared to the Dutch Study (70.3%, 108/ 153 vs 58.3%, 895/1536; p1⁄40.003086), with components of TO shown in Figure 1.
