虽然人们认识到口服胆囊造影时有些胆结石漂浮，但其原因尚不清楚。为了确定结石类型和成分与结石浮力的关系，作者分析了国家胆石症合作研究中90例患者的胆石症。17例患者在口服胆囊造影时有漂浮结石，73例有非漂浮放射性结石。结石分析显示，所有17个漂浮结石都是胆固醇结石; 64个非漂浮结石是胆固醇结石，而9个是色素结石。漂浮和非漂浮胆固醇结石的胆固醇含量相似，分别为结石重量的90.4% +/- 1.7和87.0% +/- 1.2。非漂浮性胆固醇结石的钙盐含量为3.2% +/- 0.6，而漂浮性胆固醇结石的钙盐含量仅为1.1% +/- 0.4（P = 0.02）。结果表明，漂浮性胆结石是胆固醇结石，其钙盐含量明显低于非漂浮性胆固醇结石。
Although it is recognized that some gallstones float at oral cholecystography, the reasons for this are not known. To determine how stone type and composition are related to stone buoyancy, the authors analyzed gallstones from 90 patients in the National Cooperative Gallstone Study. Seventeen patients had floating and 73 had nonfloating radiolucent stones at oral cholecystography. Stone analysis showed that all 17 floating stones were cholesterol stones; 64 of the nonfloating stones were cholesterol stones, while nine were pigment stones. The cholesterol contents of floating and nonfloating cholesterol stones were similar, 90.4% +/- 1.7 and 87.0% +/- 1.2 of stone weight, respectively. The calcium salt content of the nonfloating cholesterol stones was 3.2% +/- 0.6, while that of the floating cholesterol stones was only 1.1% +/- 0.4 (P = .02). The results indicate that floating gallstones are cholesterol stones with a significantly lower calcium salt content than that of nonfloating cholesterol stones.
