急性胰腺炎腹膜后隙的CT炎性浸润程度与临床严重程度的相关性分析

Correlation analysis of acute pancreatitis retroperitoneal clearance CT inflammatory infiltration degree and clinical severity

目的分析急性胰腺炎（AP）临床严重程度与腹膜后隙的CT炎性浸润程度的相关性。方法选择2010年6月~2012年6月间接受诊治的急性胰腺炎患者236例,对其进行CT检查,通过CT检查结果对比分析腹膜后隙的炎性浸润程度与急性胰腺炎临床严重程度。结果 236例患者中,程度不等的累及腹膜后隙196例,其中88例为轻症急性AP,累及以肾旁前间隙为主,66例为重1型急性胰腺炎,累及肾周间隙与肾旁前间隙,82例为重2型AP累及肾周间隙、肾旁前间隙、肾旁后间隙。炎性浸润与临床严重程度呈正相关（r=0.7797,P=0.001）。结论腹膜后隙的CT炎性浸润程度,特别是肾旁后间隙的受累情况,一般均会表现出急性胰腺炎的临床严重程度。

Objective To study the correlation of patients with acute pancreatitis gap retroperitoneal inflammatory in- filtration CT and clinical severity. Methods 236 cases of acute pancreatitis from June 2010 to June 2012 were collected for treatment, comparatively analyzed and compared clinical severity of inflammatory infiltration of acute pancreatitis and retroperitoneal gap though CT examination. Results A total of 236 cases of patients were selected and 196 cases of patients with varying degrees of post-gap involving the peritoneum, 88 cases of mild acute pancreatitis, mainly involv- ing the next pre-renal clearance, 66 cases of severe acute pancreatitis type 1, while involving the perirenal space next stage renal clearance in front to the main level II infiltration, 82 cases of severe acute type 2 pancreatitis, involved the perirenal space, before clearance and clearance, renal infiltration beside kidney. CT inflammatory infiltration and retroperitoneal gap clinical severity was positively correlated （r=0.7797, P=0.001）. Conclusion CT retroperitoneal in- flammatory infiltration gap, especially next to the renal clearance of involvement often reflect the clinical severity of acute pancreatitis.
