The aim of this study was to compare the high resolution ultrasonographic appearance and measurements of the gastrointestinal wall layers "in vivo" and "ex vivo". Five healthy White New Zealand rabbits were used in this study. All gastrointestinal ultrasonographic examinations were performed by the same sonographer using a real-time ultrasound machine with a high frequency (17-5 MHz) linear array transducer "in vivo" and "ex vivo" respectively. Thickness of the total gastrointestinal wall in its different tracts (stomach, duodenum, jejunum, ileum, sacculus rotundus, caecum, apex ceci, ansa spiralis coli, colon descendens) and, when it was possible, the thickness of each of its layers (mucosa, submucosa, muscularis, serosa) were obtained. Statistical differences between in-vivo and ex-vivo measurements were only found in ileum, caecum and apex ceci. Values provided in this study can be useful as baseline reference when evaluating rabbit GI disorders that can have different degree of gastrointestinal layer involvement.

Abstract
The aim of this study was to compare the high resolution ultrasonographic appearance and measurements of the gastrointestinal wall layers "in vivo" and "ex vivo". Five healthy White New Zealand rabbits were used in this study. All gastrointestinal ultrasonographic examinations were performed by the same sonographer using a real-time ultrasound machine with a high frequency (17-5 MHz) linear array transducer "in vivo" and "ex vivo" respectively. Thickness of the total gastrointestinal wall in its different tracts (stomach, duodenum, jejunum, ileum, sacculus rotundus, caecum, apex ceci, ansa spiralis coli, colon descendens) and, when it was possible, the thickness of each of its layers (mucosa, submucosa, muscularis, serosa) were obtained. Statistical differences between in-vivo and ex-vivo measurements were only found in ileum, caecum and apex ceci. Values provided in this study can be useful as baseline reference when evaluating rabbit GI disorders that can have different degree of gastrointestinal layer involvement.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
