Preliminary study of a new pathological evolution-based clinical hepatolithiasis classification

Figure 1 Primary type of pathological evolution-based classification for hepatolithiasis. A: Computed tomography showed that calculi were located within the right posterior lobe of the liver and dilation of the biliary tract within the liver; B: Magnetic resonance cholangiopancreatography showed dilation of the biliary tract and a negative calculi signal within the dilated tract; C: Operative imaging showed that a large amount of hepatolithiasis was removed surgically; D: Postoperative imaging showed calculi (in kidney basin) and specimens including gallbladder and posterior hepatic lobe, which were removed surgically.
