Hepatobiliary scanning standards fail to identify symptomatic patients with chronic acalculous cholecystitis

Abstract

Background: Patients with chronic biliary colic-like pain and normal transabdominal ultrasonography (TUS) typically undergo nuclear hepatobiliary imaging (HIDA) with cholecystokinin (CCK) injection and gall bladder ejection fraction (EF) calculation to identify gallbladder dyskinesia. Most literature suggests EF≤35% indicates biliary dyskinesia. We hypothesize that presence of chronic biliary colic-like symptoms predicts favorable outcome after cholecystectomy (CCY) in patients with normal hepatobiliary imaging.
