For the purpose of the present study to diagnose gall-bladder cancers, which cannot be detected or are only partly visible by conventional ultrasonography (US), we attempted differential diagnoses of 69 patients with gall-bladder diseases (12 with gall-bladder cancer, five with acute cholecystitis, 11 with chronic cholecystitis, 27 with cholesterol polyp and 14 with adenomyomatosis) using the evaluation of gall-bladder wall blood flow (GWBF). GWBF was evaluated by colour Doppler-guided spectral analysis (CDSA). Thirty-three healthy volunteers were selected as controls at random. Two parameters of GWBF, namely flow velocity and resistive index (RI), were compared between patients with gall-bladder diseases and healthy volunteers. GWBF could be ultrasonically evaluated in 92 (90%) of 102 subjects. All 12 patients with gall-bladder cancer had a significantly rapid blood flow value compared with other patients and healthy volunteers. There was no significant difference in RI among patients and healthy volunteers. When cut-off level of the flow velocity was set at 30cm/s, gall-bladder cancer could be diagnosed by flow velocity with 100% sensitivity (12/12) and 96% specificity (50/52). Using the same cut-off level of the flow velocity, 17 patients were analysed prospectively. In four asymptomatic gall-bladder cancers and two acute cholecystitis cases with some symptoms, the flow velocity was over 30cm/s. In two of four patients with gall-bladder cancer, only a part of the tumour was visualized on conventional abdominal US. In conclusion, CDSA was more useful for diagnosing gall-bladder lesions than the conventional abdominal US due to estimation of arterial flow velocity in the gall-bladder wall.
