Gallbladder contractile function was observed by B-mode ultrasonography on patients with radical gastrectomy for gastric carcinoma (20 cases), with subtotal gastrectomy for peptic ulcer (36 cases), and with highly selective vagotomy (7 cases). Thirty-one preoperative patients with peptic ulcer were used as control. It was found that within one month after radical or subtotal gastrectomy the average area and the volume of the gallbladder became much larger than that found in control group. The empty rate of the gallbladder was found decreased and the remainder bile increased. Early stage gallstones were found in two cases 11 and 13 months after gastrectomy. The inner diameter of the common bile duct was increased after radical gastrectomy. No definite relationship was found between gallbladder contractile disfunction and the mode of gastroenterostomy. It was also found that highly selective vagotomy had only slight influence on the biliary tract. These results suggest that gastrectomy has significant influence on the function of biliary tract and plays an important role in the formation of gallstones.
采用B型超声对20例胃癌根治术患者、36例消化性溃疡胃大部切除术患者及7例高选择性迷走神经切断术患者的胆囊收缩功能进行了观察。31例术前消化性溃疡患者作为对照。结果发现，根治性或胃大部切除术后1个月内，胆囊的平均面积和体积比对照组明显增大。胆囊排空率降低，残余胆汁增多。胃切除术后11个月和13个月分别有2例发现早期胆结石。胃癌根治术后胆总管内径增宽。未发现胆囊收缩功能障碍与胃肠吻合方式之间存在明确关系。还发现高选择性迷走神经切断术对胆道仅有轻微影响。这些结果提示，胃切除术对胆道功能有显著影响，在胆结石形成中起重要作用。
