目的 探讨外伤性胰腺炎的CT影 像表现特点。方法 选取我院于2012年2 月-2014年10月收治的81例外伤性胰腺 炎患者为研究对象,将其归入研究组(A 组,n=81)；将同期入院就诊的81例普通 胰腺炎患者纳入对照组(B组,n=81)。两 组患者均接受CT检查，观察其CT图像， 记录其在CT征象、胰腺形态、肾筋膜形 态、胰腺结构、假性囊肿发生情况、积液 情况、腹腔内游离气体情况及周围脂肪 间隙密度变化情况等CT表现上的对比差 异。结果 两组患者在肾周或胸腔积水、 肾筋膜形态改变及假性囊肿发生率等CT 表现对比上均无统计学意义(P>0.05)； A组患者中单个CT征象者56例(69.1%)， 显著高于B组患者的27例(33.3%)，差异 具有统计学意义(P<0.05)；B组患者中小 网膜积液者29例(35.8%)，腹腔积液者25 例(30.9%)，胰腺形态增大且胰腺结构清 晰者33例(40.7%)，周围脂肪间隙密度者 23例(28.4%)，腹腔内游离气体者15例 (18.5%)，均显著高于A组的9例(11.1%)， 7例(8.6%)，7例(8.6%)，7例(8.6%)和5例 (6.2%)，差异具有统计学意义(P<0.05)。 结论 CT影像学检查可作为临床鉴别外伤 性胰腺炎及普通胰腺炎的重要依据，值得 临床推广。

Objective Toexplore the CT imaging features of traumatic pancreatitis. Methods 81 cases of patientswith traumatic pancreatitis admitted intothe hospital from February 2012 to October 2014 wereslected as the research object which was included in the research group (group A, n=81), 81 cases of patients with common pancreatitis over the same period admitted into the hospital were included into the control group (group B, n=81). The two groups of patients all received CT examination. The CT images were observed. The differences in CT signs, pancreatic form, the form of renal fascia, the structure of the pancreas, the occurrence of pseudocyst, conditions of effusion andintraperitoneal free gas and the changes of surrounding fat space density were recorded. Results The differences in perirenal and pleural effusion, morphological changes of renal fascia and the occurrence of pseudocystin the two groups of patients were not statistically significant (P>0.05). There 56 cases (69.1%)of patients with single CT sign in group A which were significantly higher than 27 cases (33.3%)in group B and the difference was statistically significant (P<0.05), in group B, there were 29 cases(35.8%) of omental effusion, 25 cases(30.9%) of peritoneal effusion, 33 cases(40.7%) of enlargement of pancreatic form and distinct structure of the pancreas, 23 cases of (28.4%)surrounding fat space density, 15 cases (18.5%) of intraperitoneal free air, which were significantly higher than 9 cases (11.1%), 7 cases (8.6%), 7 cases (8.6%), 7 cases (8.6%) and 5 cases (6.2%) in group A and the differences were statistically significant (P<0.05). Conclusion CT imageological examination can be used as the important basis for clinical differential diagnosis of traumatic pancreatitis and common pancreatitis, which is worthy of clinical popularization.
