Chronic acalculous biliary disease: cholecystokinin cholescintigraphy is useful in formulating treatment strategy and predicting success after cholecystectomy.

Patients with symptoms consistent with biliary colic who do not demonstrate calculi on routine sonography present a diagnostic dilemma for clinicians. For those patients in whom other disease entities have been excluded and in whom the history and physical examination exemplify classic signs and symptoms of biliary disease we show in this study that cholecystokinin cholescintigraphy with calculation of gallbladder ejection fraction is a predictor of pathology as well as subsequent symptom relief after cholecystectomy. The spectrum of pathology that makes up chronic acalculous biliary disease lacks a distinct definition, yet this review shows that cholecystokinin cholescintigraphy offers the surgeon the means to better counsel his or her patient with regard to surgical indications, options, and benefits. We reviewed 26 patients who had no gallstones detectable, had gallbladder ejection fraction <35 per cent, and were status postlaparoscopic cholecystectomy for suspected chronic acalculous biliary disease. Our results show histopathologic evidence of chronic cholecystitis in 100 per cent, and 92 per cent of the patients had improvement of symptoms and satisfaction with the operation to the point that they would undergo the surgery again without reservation.
