We evaluated the plain films of the abdomen and chest in 24 patients with documented extraperitoneal gas collections. Compartmental localization of the extraperitoneal ectopic gas in these patients was as follows: the anterior pararenal space in 10 patients, the perirenal space in five and the posterior pararenal space in 15. In six of these 24 patients, the extraperitoneal gas was present in two compartments. The extraperitoneal gas collection resulted from perforation of the retroperitoneally located alimentary tract in 11, necrotizing pancreatitis in five, gas-producing infection in four and from extension of extra-alveolar air in three patients. Air insufflation of the scrotum was the cause of the extraperitoneal gas in another patient.
我们对24例有腹膜外气体积聚记录的患者的腹部和胸部平片进行了评估。这些患者腹膜外异位气体的分区定位如下：10例位于肾前间隙，5例位于肾周间隙，15例位于肾后间隙。在这24例患者中，有6例腹膜外气体存在于两个间隙。腹膜外气体积聚的原因如下：11例是由于腹膜后消化道穿孔，5例是坏死性胰腺炎，4例是产气感染，3例是肺泡外气体扩展。另1例患者腹膜外气体是由阴囊充气引起的。
