| Popis: | Our purposes were to determine whether sonography can distinguish between obstructed and nonobstructed rats and to compare the diagnostic accuracy of sonography and radiography in the diagnosis of small bowel obstruction. Nonstrangulating small bowel obstruction was created in 19 rats; sham laparotomies were performed in 18 controls. Serial radiographs and sonograms, including duplex Doppler sonography, were obtained. Bowel diameter and bowel wall thickness were evaluated retrospectively. Bowel diameter, bowel wall thickness, and resistive indices increased in the animals with obstruction; controls remained unchanged (P = 0.002). Sonography demonstrated a significantly higher diagnostic accuracy than radiography at 24 hours and beyond (P = 0.023). Ultrasonography is sensitive and more accurate than radiography in diagnosing small bowel obstruction using objective criteria in the animal model. |
