Morphine-augmented versus cck-augmented cholescintigraphy in diagnosing acute cholecystitis

Cholescintigraphy was performed after pharmacological manipulation in 60 patients with a clinical suspicion of acute cholecystitis and non-visualization of the gallbladder 1 h after⁹⁹Tc^m-DISIDA cholescintigraphy. Thirty patients received an intravenous (i.v.) injection of CCK(groupI)The sensitivity, specificity, positive predictive value were 94, 100, 100 and 93% in group I and 100, 84, 79 and 100% in group II, respectively. There was a significant difference between groups (P<0.05). In conclusion, morphine-augmented cholescintigraphy could supply more reliable diagnostic information and is less time-consuming in patients with a clinical suspicion of acute cholecystitis.
