Bowel and mesenteric injuries are common sequelae of blunt abdominal trauma. CT represents a valuable modality in the diagnosis of bowel and mesenteric injuries. While certain findings on CT are highly specific, such as free air and extravasation of oral contrast agent, they are insensitive and seen only in the minority of patients. Therefore, radiologists must focus their attention on the bowel wall and mesentery to improve their diagnostic accuracy in these injuries. Bowel wall thickening and/or abnormal bowel wall enhancement must be noted. Mesenteric abnormalities, which can consist of mesenteric infiltration, interloop fluid, or fluid trapped in the leaves of the small bowel mesentery, may be crucial yet subtle clues. Knowledge of their typical appearance may aid in their diagnosis. This pictorial essay illustrates the range of findings in bowel and mesenteric injuries as well as possible pitfalls to help in their prompt recognition and diagnosis.
肠管和肠系膜损伤是钝性腹部创伤的常见后遗症。CT是诊断肠管和肠系膜损伤的一种有价值的方法。虽然CT上的某些表现具有高度特异性，如游离气体和口服对比剂外渗，但它们不敏感，仅在少数患者中出现。因此，放射科医生必须关注肠壁和肠系膜，以提高对这些损伤的诊断准确性。必须注意肠壁增厚和/或肠壁强化异常。肠系膜异常包括肠系膜浸润、肠袢间积液或小肠肠系膜叶间积液，可能是关键但细微的线索。了解其典型表现可能有助于诊断。这篇图文并茂的文章阐述了肠管和肠系膜损伤的一系列表现以及可能出现的陷阱，以帮助及时识别和诊断。
