Supine abdominal radiographs of 59 patients with documented pneumoperitoneum were evaluated for findings of pneumoperitoneum. The commonly described signs were seen in only 17%. Localized intraperitoneal air in the right upper quadrant was the most frequent finding, seen in 49% of patients. Identification of these collections of air is dependent upon knowledge of the anatomy of the perihepatic spaces.
对59例有气腹记录患者的仰卧位腹部X线片进行气腹表现评估。通常描述的征象仅在17%的患者中出现。右上腹局限性腹腔内积气是最常见的表现，见于49%的患者。这些积气的识别取决于对肝周间隙解剖结构的了解。
