ABSTRACT

Objective:

To investigate the effects of different local complications of acute pancreatitis (AP) on the microcirculation of multiple organs in the upper abdomen.

Methods:

A dynamic volume perfusion computed tomography (DVPCT) scan in the upper abdomen was prospectively conducted in 101 patients with AP and 24 patients with neither AP nor other obvious upper abnominal lesions diagnosed in People′s Hospital of Deyang City from April 1 to October 31, 2019, 86 patients with AP (AP group) and 21 controls (control group) were enrolled in the study. AP patients were divided into no local complications group (21 cases), acute peripancreatic fluid collection (APFC) group (19 cases), acute necrotic collection (ANC) group (27 cases), walled-off necrosis (WON) group (11 cases) and walled-off necrosis with infection (WONI) group (8 cases). The blood flow (BF) of pancreas, liver, spleen, two kidneys and adrenal glands was measured by deconvolution. The hepatic arterial perfusion (HAP), hepatic portal perfusion (HPP) and hepatic perfusion index (HPI) of each group were calculated by maximum slope. T test was used for statistical analysis.

Results:

The BF of pancreas, spleen and left adrenal gland of ANC group was (139.89±34.28), (141.42±47.85) and (107.87±26.41) mL·min -1·(100 g) -1, respectively, the BF of pancreas, spleen and left adrenal gland of WON group was (130.00±44.83), (106.12±38.16) and (98.38±41.39) mL·min -1·(100 g) -1 respectively, and the BF of pancreas, spleen and left adrenal gland of WONI group was (127.91±35.86), (102.09±23.73) and (105.66±27.01) mL·min -1·(100 g) -1, respectively, which were all lower than those of control group ((161.22±31.60), (174.00±62.73) and (134.53±36.36) mL·min -1·(100 g) -1), and the differences were statistically significant ( t=2.440, 2.043, 2.943; 2.296, 3.796, 2.548; 2.448, 4.479, 2.154; all P<0.05). The BF of left kidney cortex of WONI group was lower than that of control group ((247.44±39.32) mL·min -1·(100 g) -1 vs. (294.80±39.13) mL·min -1·(100 g) -1), and the difference were statistically significant ( t=2.910, P<0.05). The HAP of ANC group, WON group and WONI group was (18.63±9.54), (19.10±7.47) and (19.51±6.26) mL·min -1·(100 g) -1, respectively, and the HPI was (25.01±15.51)%, (45.98±31.42)% and (35.92±24.95)%, respectively, which were all higher than those of control group ((12.18±5.14) mL·min -1·(100 g) -1 and (13.44±6.49)%), and the differences were statistically significant ( t=2.997, 3.088, 3.235; 3.503, 3.397, 2.517; all P<0.05) . The HPP of ANC group, WON group and WONI group was (72.37±21.76), (48.83±35.10) and (57.55±29.45) mL·min -1·(100 g) -1, respectively, which were all lower than that of control group ((86.43±17.98) mL·min -1·(100 g) -1), and the differences were statistically significant ( t=2.391, 3.331 and 3.226, all P<0.05). The HAP and HPI of APFC group were both higher than those of control group ((18.67±10.24) mL·min -1·(100 g) -1 vs. 12.18±5.14) mL·min -1·(100 g) -1 and (23.75±20.41)% vs. (13.44±6.49)%), and the differences were statistically significant ( t=2.572 and 2.108, both P<0.05) .

Conclusions:

AP complicated with ANC, WON and WONI can reduce the BF of pancreas, spleen and left adrenal gland, and WONI can induce the decrease of BF of left kindney cortex. AP complicated with ANC, WON and WONI can increase HAP and HPI, but decrease HPP. Furthermore, AP complicated with APFC can increase HAP.
