■从胃肠道穿孔异物,比如木串,在小动物文献中报告了在胸部产生炎症/感染性病变,腹部,和肌肉骨骼系统,在某些情况下可能会危及生命。已经使用了几种成像模式,和先进的成像技术在其诊断和手术前计划中显示出巨大的优势。
■这项研究的目的是描述一组七只中大型犬的计算机断层扫描结果,这些犬具有穿孔的木串和从胃肠道迁移的异物。
■在医疗记录数据库中搜索了怀疑诊断为从胃肠道迁移的穿孔木制异物的狗,并进行了计算机断层扫描研究。信号,历史,并检索了临床病理发现(如果有),并对计算机断层扫描研究进行了综述。
■临床体征因穿通途径受累的解剖区域而异。所有异物均被识别,并显示出79HU的中值衰减,最常见的定位是胃,其次是空肠。穿孔部位周围的腹膜脂肪绞合是最常见的计算机断层扫描发现。腹膜游离液和/或气体的存在并不常见。胸腔积液,肺穿孔,大多数情况下存在气胸,异物穿过胸膜腔。当木串的末端在肺实质内时,总是报告肺空洞病变。在所有末端尖端卡在肌肉或皮下组织中的情况下,都可以识别出软组织脓肿。
■研究结果支持这种异物引起的继发性病变的变异性以及计算机断层扫描在识别中的实用性,以及木串的鉴定。
UNASSIGNED: Perforating foreign bodies from the gastrointestinal tract, such as wooden skewers, are reported in the small animal literature producing inflammatory/infectious lesions in the thorax, abdomen, and musculoskeletal system, which can be life-threatening in some instances. Several imaging modalities have been used, and advanced imaging techniques have shown a great advantage in its diagnosis and pre-surgical planning.
UNASSIGNED: The objective of this study is to describe the computed tomographic findings in a group of seven medium to large breed dogs with perforating wooden skewers and foreign bodies migrated from the gastrointestinal tract.
UNASSIGNED: The medical records database was searched for dogs with a suspected diagnosis of a perforating wooden foreign body migrated from the gastrointestinal tract in which a computed tomographic study was performed. Signalment, history, and clinicopathological findings (when available) were retrieved, and the computed tomographic studies were reviewed.
UNASSIGNED: Clinical signs vary depending on the anatomical regions affected through the perforating pathway. All foreign bodies were identified and showed a median attenuation of 79 HU, with the most common localization being the stomach followed by the jejunum. Peritoneal fat stranding surrounding the perforation site was the most frequent computed tomographic finding. The presence of peritoneal free fluid and/or gas was uncommon. Pleural effusion, pulmonary perforation, and pneumothorax were present in most of the cases with the foreign body traversing the pleural space. Pulmonary cavitary lesions were always reported when the ending tip of the wooden skewer was within the pulmonary parenchyma. Soft tissue abscessation was recognized in all cases where the ending tip was lodged in muscular or subcutaneous tissues.
UNASSIGNED: Findings supported the variability of the secondary lesions caused by this type of foreign body and the utility of computed tomography in their recognition, as well as in the identification of the wooden skewer.
