Comparison of CT features between hyperlipidemic acute pancreatitis and acute biliary pancreatitis

Objective To analyze the difference of CT features between hyperlipidemic acute pancreatitis (HLAP) and acute biliary pancreatitis (ABP).

Methods Retrospective analysis was performed on 66 HLAP patients and 96 ABP patients admitted to East Hospital Affiliated to Tongji University from January 2018 to December 2019. The clinical data and CT features of patients between the two groups were compared.

Results There were statistically significant differences in the clinical data and CT grades (A-E) between the HLAP group and the ABP group (P＜0.01). ABP group showed more swelling and effusion in pancreatic body and tail (58.3%), 16.7% of swelling and effusion in whole pancreas, but rare swelling and effusion located in pancreatic head and neck alone (3.1%). The HLAP group showed more swelling and effusion in whole pancreas (48.5%), 39.4% of swelling and effusion in pancreatic head and neck, but rare swelling and effusion located in pancreatic body and tail alone (12.1%).

Conclusions CT features of HLAP are significantly different from the ABP, which may be useful for early precise diagnosis and treatment for HLAP.
