Enterobiliary fistulae: a potential cause of a false-negative hepatobiliary study in the diagnosis of acute cholecystitis.
Cholescintigraphy has gained widespread acceptance in detection of acute cholecystitis (AC). Gallbladder (GB) visualization within 4 h effectively rules out A.C. with a high degree of specificity. We present a case of A.C. in a patient who had a normal scintigraphic appearance of the G.B. at 30 min with what appeared to be entero-gastric reflux, and which retrospectively proved to be A. C. with a cholecystocolic fistula.
