Abstract
To calculate the incidence of acute peripancreatic fluid collection (APFC) in patients with acute pancreatitis. The secondary objective is to determine the underlying etiologies of acute pancreatitis in the Saudi population.
A retrospective cohort study was carried out at King Khalid University Hospital, King Saud University, Riyadh, Saudi Arabia. The study analyzed data from patients who were diagnosed with acute pancreatitis between January 2008 and January 202. A total of 327 were included in the study after applying the inclusion and exclusion criteria. Their medical records were subsequently reviewed for the presence or absence of APFC on follow-up imaging studies, evidence of biliary stones, prior endoscopic retrograde cholangiopancreatography (ERCP), a history of alcohol use, and demographic variables.
Of the 327 patients with acute pancreatitis, 158 (48.3%) developed APFC, while 169 (51.7%) did not. The majority of patients had an idiopathic etiology of acute pancreatitis (n=251; 76.8%); followed by a biliary etiology (n=51; 15.6%); post-ERCP complications (n=14; 4.3%), and other causes (n=11; 3.3%).
The incidence of APFC in patients presenting with acute pancreatitis between January 2008 and January 2021 was 48.3%. The most common etiology of acute pancreatitis in this tertiary care hospital was idiopathic, followed by biliary etiologies and post-ERCP complications. More studies targeting the local complications of pancreatitis are needed to reach more definitive findings.
