美国医学家发现了用简便的乙醚注射法代替昂贵的胆囊切除术。他们通过细管在36例胆结石患者的胆囊中注入乙醚溶液。由于80％的胆结石是由胆固醇组成,所以乙醚很容易使之溶解。据有关专家估计目前美国每年200,000例胆结石患者中至少有一半可用乙醚注入法进行治疗。这种方法简便经济,费用仅为胆囊切除术的四分之一,病人仅需休养2 American medical scientists found a simple ether injection instead of expensive cholecystectomy. They injected a small amount of ether into the gallbladder of 36 patients with gallstones through a thin tube. Because 80% of the gallstones are made of cholesterol, it is easy to dissolve with ether. According to some experts, at least half of the 200,000 gallstone patients in the United States are currently treated with ether injection. This method is simple and economical, the cost is only a quarter of cholecystectomy, patients only need to rest 2
