title: Specific but limited role of new imaging techniques in decision-making about intraabdominal abscesses.
abstract: Despite the very high accuracy rate of imaging studies (ultrasound, computed tomography, liver-lung-spleen scans and gallium-67 scans) in detecting intraabdominal abscesses, our experience with 80 recent cases indicate that these techniques have not significantly altered traditional methods of decision-making about when and where to drain such abscesses. In only 12.5 percent of cases were such decisions based on special imaging techniques alone, and most of these cases subphrenic abscesses were diagnosed late after surgery. In the remainder, physical examination and routine radiologic studies sufficed, with special imaging techniques primarily corroborating clinical evidence based on these methods. We conclude that the use of special imaging techniques alone in a search for the cause of fever early after abdominal surgery does not provide evidence upon which clinical decisions can be based unless there are already physical signs of an abscess.
