ABSTRACT
Objective To study the correlation between the manifestations of the left subphrenic fat infiltration (LSFI) and the severity of acute pancreatitis (AP) Methods One hundred and forty four cases and 188 cases of AP scored by Ranson′s scoring system and graded by Balthazar′s staging system were retrospectively studied respectively The thickness of the LSFI in each case was respectively and individually observed and measured, and the thickness under 3 mm was graded as 0 of which the sign of LSFI was considered as negative Rank correlation analysis of the thickness of LSFI with Ranson′s scoring and Balthazar′s staging was used respectively Results The incidence of LSFI in Ranson′s rank 1-3 was 30 86%, 54 90%, and 75 00%, respectively, and rank correlation coefficient of LSFI and Ranson′s score was 0 417 9( P
