Three cases of gastrointestinal perforation diagnosed by ultrasonography (US) are described. In these patients US showed the presence of gas in peritoneum, anteriorly to the liver. Gas is easily identified by US for its unique aspects. More difficult may be the diagnosis of its site, external to the gastrointestinal tract. Differential diagnosis, limits and possible pitfalls are briefly discussed.
本文描述了3例经超声检查诊断为胃肠道穿孔的病例。在这些患者中，超声显示肝脏前方的腹膜内存在气体。气体因其独特的表现很容易被超声识别。而诊断气体在胃肠道外的位置可能更困难。本文简要讨论了鉴别诊断、局限性及可能存在的陷阱。
