title: [Ultrasonic diagnosis of gastrointestinal perforation].
abstract: 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.
