Abstract

BACKGROUND Pancreatic injuries from blunt abdominal trauma have a high mortality rate, often accompanied by injuries to adjacent organs. This study aims to investigate the relationship between the size of retropancreatic adipose tissue and the severity of pancreatic and adjacent organ injuries in patients with pancreatic trauma. METHODS We retrospectively screened computed tomography (CT) images of 34 patients (25 males, nine females, aged 13-69 years) and 34 controls (28 males, six females, aged 15-66 years) who suffered blunt abdominal trauma. The area of adipose tissue located posterior to the pancreatic body was measured in the axial plane for all subjects. The severity of pancreatic injury was assessed in terms of the injury site, the retropancreatic adipose tissue area, and the degree of other organ injuries. RESULTS Pancreatic injuries were located in the head for 16 patients (23.5%), in the body for four patients (5.9%), and in the tail for 14 patients (20.6%). The retropancreatic fat area was found to be significantly smaller in patients with pancreatic trauma compared to controls (p<0.0001). Furthermore, the ratio of the retropancreatic fat area to the vertebral corpus area differed significantly between patients with and without pancreatic injuries (p=0.014). CONCLUSION Retropancreatic adipose tissue protects the pancreatic body from the impacts of blunt abdominal trauma. An increased amount of retropancreatic adipose tissue is associated with a reduced rate of pancreatic injury.
CT 上钝器伤导致的胰腺损伤:胰腺后脂肪组织能否减轻胰腺损伤的严重程度?
背景腹部钝性创伤造成的胰腺损伤死亡率很高,通常还伴有邻近器官的损伤。本研究旨在探讨胰腺外伤患者胰腺后脂肪组织的大小与胰腺及邻近器官损伤严重程度之间的关系。方法 我们回顾性地筛选了 34 名腹部钝性外伤患者(25 名男性,9 名女性,年龄 13-69 岁)和 34 名对照组患者(28 名男性,6 名女性,年龄 15-66 岁)的计算机断层扫描(CT)图像。在轴向平面上测量了所有受试者位于胰腺体后方的脂肪组织面积。根据损伤部位、胰腺后脂肪组织面积和其他器官损伤程度评估胰腺损伤的严重程度。结果 16 名患者的胰腺损伤位于头部(23.5%),4 名患者的胰腺损伤位于体部(5.9%),14 名患者的胰腺损伤位于尾部(20.6%)。与对照组相比,胰腺外伤患者的胰腺后脂肪面积明显较小(P<0.0001)。此外,胰腺后脂肪面积与椎体面积的比值在有胰腺损伤和无胰腺损伤的患者之间存在显著差异(p=0.014)。胰腺后脂肪组织的增加与胰腺损伤率的降低有关。
