Abstract

Abstract:

Objective To explore the clinical value of retroperitoneal space (RPS) inflammatory infiltration, pleural effusion and peripancreatic effusion in evaluating the severity of acute pancreatitis (AP). Methods A retrospective analysis was conducted on 108 patients with AP, and their CT severity index (CTSI) grading and RPS inflammatory infiltration grading were performed to clarify the correlation between RPS inflammatory infiltration, pleural effusion, peripancreatic effusion and clinical severity of AP. Results According to the CTSI grading, 53 AP patients with grade Ⅰ AP were diagnosed, and the degree of RPS inflammation infiltration was mainly grade A. The detection rate of pleural effusion in the early stage (within 48 hours after the onset) was 11.32%, the incidence of peripancreatic effusion was 54.72%, and the number of peripancreatic effusion was mainly 1. Of the 31 AP patients with grade Ⅱ, the degree of RPS inflammatory infiltration was mainly grade C. The detection rate of early pleural effusion was 38.71%, the incidence of peripancreatic effusion was 80.65%, and the number of peripancreatic effusion was mainly 1 or 2. There were 24 AP patients with grade Ⅲ and the degree of RPS inflammatory infiltration was mainly grade D. The detection rate of early pleural effusion was 70.83%, the incidence of peripancreatic effusion was 95.83%, and the number of peripancreatic effusion was 3 or more. The degree of RPS inflammatory infiltration and the detection rate of early pleural effusion in AP patients were positively correlated with the CTSI grade (r_s=0.818, P<0.05; r_s=0.990, P<0.05). The number of peripancreatic effusion in AP patients increased with the increase of CTSI grade. Conclusion The degree of RPS inflammatory infiltration, pleural effusion and peripancreatic effusion are closely related to the clinical severity of acute pancreatitis, and should be given sufficient attention in clinical practice.
