Abstract: | This work attempts to assess the diagnostic accuracy of ultrasound for acute cholecystitis in 98 clinically suspected patients from the emergency unit in whom at least 3 of 6 relevant criteria are present. Gallbladder distention to 5 cm or more transversely or in the anterior-posterior axis (criterion 1) was present in 64 patients; thickening of the gallbladder wall of at least 5 mm (criterion 2) in 95; cholelithiasis (criterion 3) in 86; sonolucent halo in the gallbladder wall (criterion 4) in 40; sonolucent fluid band surrounding the gallbladder (criterion 5) in 27; and intraluminal echogenic mass with no posterior acoustic shadow (criterion 6) in 35. A diagnostic accuracy index, corrected for chance, was statistically and clinically more relevant with 3 as the minimum number of criteria for the ultrasonic diagnosis of acute cholecystitis. |
