HPB P25 Incidence of pancreatitis induced vascular complications in a tertiary care hospital

Abstract Background Pancreatitis (AP) is a common cause of hospital admission, which can lead to vascular complications such as splanchnic venous thrombosis (SpVT), pseudoaneurysm and haemorhage. These complications can happen with both acute and chronic pancreatitis and can be associated with high morbidity and mortality. The aim of this study was to assess incidence of vascular complications in acute pancreatitis patients in a tertiary care hospital. Secondary aims included describing patient demographics, length of hospital stay, critical care admission, mortality, and assess the association between SpVT and pancreatic necrosis and mortality. Methods This study was done as part of year five elective project in University of Aberdeen Medical School. A retrospective study of acute pancreatitis patients who stayed in Aberdeen Royal Infirmary (ARI) or Dr. Gray's Hospital for ≥2 weeks and cases of mortality from acute pancreatitis irrespective of hospital stay between January 2018 to December 2019. Cases were identified from Health intelligence central data as per local governance protocol. Hospital electronic system (TrackCare) was used to review the clinical and radiological details and data was entered in SPSS software version 27 for analysis. Frequencies and percentages were shown for the categorical data and chi square test was used to compare the variables. A p value less than 0.05 was taken as statistically significant. Results Total 293 patients were admitted with acute pancreatitis during the study period. 52 patients met the inclusion criteria for our study. Of the 52 patients, 50 patients had a CT scan. There were 12 patients (24%) with evidence of vascular complications. 22% of patients had SVT and pseudoaneurysm was seen in 2% of cases. There was no case of haemorrhage. The overall mortality from AP during the study period was 6.5%. There was no statistically significant association between SVT and pancreatic necrosis or mortality. Conclusions Splanchnic venous thrombosis was a more frequent complication compared to pseudoaneurysm and haemorrhage in AP. There was no association between SVT and necrosis or mortality.
