Acute acalculous cholecystitis. Ultrasonic diagnosis.
Ultrasonography is an effective and accurate diagnostic test for acalculous cholecystitis. Until recently, however, little attention was focused on the gallbladder wall as an indicator of disease. By accurately visualizing and measuring the gallbladder wall, ultrasonography can be used to screen patients in whom acute acalculous cholecystitis is suspected. If the gallbladder wall measures 3.5 mm or greater, in the absence of ascites, a diagnosis of acalculous cholecystitis can be made safely with a specificity greater than 98 percent. Four of our five patients with acute acalculous cholecystitis had ultrasonically measured gallbladder walls 3.5 mm or greater in width. We have found ultrasonography useful in any clinical situation, even in the face of ileus, jaundice or pancreatitis. In addition, with the use of the portable real-time ultrasound machine, postoperative, traumatized and other critically ill patients can be examined at the bedside.
